PHP: URL variable that is unnamed

Suppose I have
<a href="foo.php/?foo"
How would I get at that URL variable?
If I print_r($_GET), I just get an array....

PHP URL Variable from Insert Record Issue

I have a very simplistic forum style website I have put together. Everything is functionally properly except for one aspect. The basic structure is a page that lists the existing threads (ie: ThreadA, ThreadB, and ThreadC). I have the name of these threads stored in a MySQL database table that is used to generate a repeating dynamic table to grow as the number of threads increases. If the user clicks on one of these links they are taken to a page that displays all of the comments pertaining to that thread. All of the comments are stored in another MySQL database table. I perform a query on this comments page to filter the information in the comments database by the thread name which is passed over from the first page via a URL variable. The link attached to the name of the thread in the repeating table that generates the URL variable is "comments.php?thread=<?php echo $row_threads['threadName']; ?>" This works perfectly, If the user clicks on ThreadB they are taken to the comments page where only the comments pertaining to ThreadB have been filtered and displayed. After the user inserts a comment form ThreadB the comments page reloads displaying the newly created comment.
Also, on the first page, the user has the option to create a new thread; call it ThreadD. The name of this new thread has to be inserted into two tables; one in the master threads table and one in the comments page any time someone adds a comment. (I'm sure there is a better way to structure this, but this was all I could figure out and for my purposes at hand it is sufficient). When the user is taken to this new comment page I have a query set up to pull the last entry in the threads table from the logged in user, ie the newly created thread topic. I have dragged this query to the page to make sure it is pulling the correct thread heading, and it works just fine. What I'm wanting to have happen is after the user enters the first comment I'm wanting them to be redirected to the main comments page with their new comment listed; giving the illusion that the new comment and existing comments page are the same. I'm trying to pass the newly created thread name, ThreadD, in the URL to the main comments page just like I do if they select it from the existing threads page. Under the insert record wizard I click the 'browse' button to select the comments.php page. I then select 'parameters' to add the thread name query as the URL parameter. The generated code is "comments.php?thread=" . $row_threadName['threadName'] . "". The user does go to the main comments page but the URL variable is not coming with it. What I'm left with in the address bar is ..."/comments.php?thread=&" , but it should be ..."comments.php?thread=ThreadD". I tried copying and pasting the URL link from the existing threads page since that works perfectly, and when I do that the main comments page shows up blank after being redirected from the new comments page. If I hard code this, for testing purposes, into the redirect after insertion section (ie: "comments.php?thread=ThreadD") everything works perfectly and the URL in the address bar of the main comments page is "...comments.php?thread=ThreadD&" I noticed the extra "&", but didn't give it much thought since the site is giving me the behavior I'm looking for. My question is, how do I get this new comment page to pass the variable of the newly created thread name to the main comments page to behave like it does when the thread is selected from the list of existing threads? I know it has to do with how the URL variable is either being generated or built from my query, or how I have it listed in the redirect section of the insert wizard, but I can't figure out where I am going wrong. Please let me know if there are any questions or if I need to clarify any aspect. Any and all help is always appreciated. Thank you.

Ok, so just to summarize so I am understanding this correctly. You have an ordering page for tires/wheels. A customer places an order for tires/wheels and the data is submitted successfully and this includes a symbol for measurement (in.). But on another summary page the symbol is returning a blank value.
If this is correct we need to see:
- First, the code that is inserting the symbol to the database table in question
- Second, the query and code where you are printing the data to the screen.

Display all database results with URL variable?

Hi,
I am using PHP MySQL
I have a database that is Alphabetically ordered. I am trying to create a dynamic page that will only show A, B, C, ... and so on. I do this by Creating links named after the letters in the Alphabet. I have a recordset that filters the table using a URL variable that uses Type. Unfortunately when I click on the link it only displays the first record that contains an A. Not all the records that contain A.
For example:
I have a link that is just "A". Its link is ?Type=A. In the database table their are 3 records that contain A under Type, but when I click on it only one record containing A is displayed. I hope you are following this.
If you want a direct reference to what I am doing go to:
http://cwhazzoo.com/gamelinktesting.php
This is how my database is designed:
ID (primary key)
Name
Letter
0001
Example A
A
I want to be able to show only the selected letter of records using only one page. Thanks!

>Should I use the repeat region?
Yep. That's what it's for.

Can you pass an array URL variable

Hi,
Doing a form which I want to validate, then re-display with
error messages and the keyed data still in place should there be
errors, or go onto a second form if all ok.
I have tried to use <form
action="<?=$_SERVER['PHP_SELF']?>" but as the various
outcomes result in different screens I can't see how to do it
without having reams of duplicate code - I couldn't make it work
satisfactorily anyway.
So I decided to do it in two stages - form (user screen) + a
separate validation routine which passes validation results back if
there are errors by calling the first screen but with URL variables
to trigger process variations or go onto screen 2 if all ok.
But I'm struggling with this .. two questions:
i) Ideally I would like to use a session variable to pass
actual error messages back to screen one in the event of errors but
if I undertand things correctly (which is by no means certain)
$S_Session is already an associatve array so it wouldn't be so easy
to just add a variable number of messages to it and then know what
you are unpacking elsewhere ... do you know what I mean?
Perhaps if I give you my second question it may help
illustrate what I'm going on about in part 1
ii) The way I have tried to do it is to set it up as an array
($ERRORS) in the validation module and then added a text string
each time I hit a specific error. The hope was that I could then
send this back via the URL for further process but I'm getting
syntax problem so maybe this is not possible .... a brief example
Input Form php:
$ERRORS = array();
$ERRORS = $_GET['errors']
if (sizeof($ERRORS) > 0) {
echo "<p class=\"val_err_hdr\"> *** Validation
error(s) - please correct the entries and try again ***
</p>";
blah blah
Validation php:
$ERRORS=array();
if(!$loginFoundUser) {
$ERRORS[] = "This e-mail address entered has already been
registered on our database - if you have already registered you
can"; }
header("Location: input.form.php?errors=$ERRORS");
When I run this I get a syntax error 'unexpected T_IF' on the
'sizeof'' function condition.
Any help much appreciated.

OK, quite common.
> I have tried to use <form

Avoid short open tags, they are unreliable. Use "<?php
print " instead
of just "<?=" to be safe and independent from the server
configuration.
>but as the

What's a "screen" in this case? Just another part of the form
or a
completely different page?

Don't use URL parameters in such a form processing scenario.
Use a
session instead, that's what they are for. The length of URLs
is limited
and there are things you simply don't want to pass between
pages, but
keep on the server instead.

The $_SESSION array itself is strictly associative, the used
indexes
must be strings or the serialization of the session data will
fail.
But if course you can always do things like this:
$_SESSION['errors'] = array();
$_SESSION['errors'][] = 'something went wrong';

As said above - use the session instead.
> Input Form php:

There's a ';' missing at the EOL (this causes the error you
mentioned
below).
Just a naming hint: Variables should not be named all
uppercase (except
for the predefined superglobal arrays). Such names should be
reserved
for constants. The most common style looks like this:
myNiceFunction()
$myNiceVariable
MY_NICE_CONSTANT
> if (sizeof($ERRORS) > 0) {
if (!empty($_SESSION['errors'])) {
> header("Location: input.form.php?errors=$ERRORS");
The Location URI must be absolute including scheme and
hostname. This is
required by the HTTP spec:
header("Location:
http://$_SERVER[HTTP_HOST
But I'm still not sure why you would need this redirect. The
entire
handling of a form (validation, processing) can be done on a
single
page. Only if the processing succeeds, you might want to
redirect to
some result page.

Url variable doesn't work in IE

Hey guys, my page, www.powerhouse.com/Products/Inventory.php I have a bunch of links that reload the page with a url variable. If FF 3, this works fine, yet in IE 8 the page does not load. My error log has the following error:
script '/var/www/powerhouse/public_html/Products/inventory.php' not found or unable to stat
what stupid IE Hack do I need to get this to work?

You don't need any IE hack. I have just tested the page in both FF and IE8. It works just fine in both.
However, it's very noticeable from your error log that it refers to inventory.php (all lowercase), whereas the actual page is Inventory.php (initial cap). The other thing that's noticeable is the path, which indicates your server is running on Linux, which is case-sensitive.
From this, I conclude that you originally coded the page using inventory.php, and later updated it. This suggests that IE8 is probably still using a cached version. Clear your cache, and the problem will probably go away.

Dynamic list to generate url variable

Hello, I am using a dynamic list to pull product codes from a
database. I then want to pass the code into a url variable when it
goes to the results page. This is so customers can chose which code
they want to go to a detail page about. I already have the dynamic
list working, I just can not figure out how to embed the selected
code into a url variable. For example I want it to do the
following:
sitename.com/search.php <--- here is where you start and
make the selection then it brings you to:
sitename.com/details.php?code=202 <---- code202 was
selected on previous page in dynamic list.
I know how to do it by pulling results from a database and
generating links for each one, but I need to do it from a dynamic
drop down list.
Here is the coding that I was trying to use:
Thank you for your assistance.

Sorry, dumb error on my part. Used method=post rather then
get.

How to use url variables?

for example: www.blah.com/blah.php?id=1
in this case, the url variable passed is id with a default value 1.
what I am trying to do is to make the webpage display different things depend on the id value.
so, a basic syntax problem... is this the correct way to do this?
<body>
     switch (id)
          case 1: echo("something");
          case 2: echo("something else");
etc
(or am I missing some dollar sign or something?)
also, how do i declare a variable in the body?
just...
int someVar;
like in java? or?

Just so you'll know, such questions are more suited for the AppDev forum -
http://forums.adobe.com/community/dreamweaver/dreamweaver_development
I'll answer here, but in the future, new threads should be begun over there.
Assuming PHP, in the head of the page you would have -
<?php
$id = isset($_GET['id'])?$_GET['id']:FALSE; // This loads the variable $id with the value of the URL variable
?>
Then you could have -
<body>
<?php
switch ($id) {
          case '1':
               echo("something");
               break;
          case '2':
               echo("something else");
               break;
?>
(I forget whether that value is passed as a string or a number, so you may have to adjust the case statements.)

Passing URL variable on login redirect

I first want to say thank you for all the great help I have received on these forums over the past couple months - it has been very helpful and saved me countless days.
Saying that, I do have another problem. I would like to pass a URL variable to the success redirect page when users login. I want to have a recordset on the login page that retrieves an issueid for the most current article and then passes it on the URL to the page that is loaded when a user successfully logins. I have tried adding the recordset to the login page and then changing the URL for the successful redirect on the tNG_config.inc.php file to:
$tNG_login_config_redirect_success["5"] = 'dashboard_issue.php?issueid=' . $currentIssueId . '';
but it isn't working. I have a tried as many variations of that syntax as I could think of or find searching online but still no luck. There might be a much easier way to do this but the way the dashboard_issue page is set up is that it is looking for the issueid in the url. The benefit being that the same page can be used for any issue that the user wants to change to once he is logged in.
I hope this is making some sense. If not please let me know.
Thanks!
-Dan

The most current issue is actually just the one that is closest to today's date in the future. Users are free to add as many issues as they want in the past and future so I really can't go by issueid to sort since it might come in any order. Right now I have the most current issue found with this query:
SELECT issueid, DATE_FORMAT(date, '%W, %M %d, %Y') 'date' FROM issues WHERE date >= CURDATE() LIMIT 0,1
I will try to explain the problem a little more. This works great for what I need to do for this page as soon as they log in since it doesn't even look at the URL at all. If a user wants to go to a different issue I display a different page (which is this page just renamed) where the recordset looks at the URL issueid variable instead of the most recent issue recordset. The problem with this setup is that it is hard to maintain 2 pages all the time and would be great if I can just have one page to handle everything.
Is it possible to do something like this?:
IF issueid url variable EXISTS THEN use recordset1
IF issueid url variable DOES NOT EXISTS use recordset2
with recordset1 being the one that grabs the most current issue and recordset2 being the one that pulls the issue information based on the url issueid.

Passing URL Variables, Can "Or" statement applies?

in my php data, i have 2 catagorical data
cat1
cat2
most of the time, since most items have single catagory, i
can just pass 1 url variables, for ex: ?cat1=5
but on rare occasions, some of my items will have 2
attributes, making it necessary to filter not only cat1=5, but
maybe cat2=5 as well.
the way you do "and" statement is just with ampersand sign
&, but how would you do "or" statement?
(or am i totally misinterpretting the way that URL variables
work? i also thought that the filtering process might occur at the
webpage, and the & statement merely passes 2 or more variables,
while the webpage decide what to do with them. am i correct in this
statement instead?)
thanks again!
p.s. do you get anything when i declare you the official
answer? like, is there a forum level up thingy which you become
like master guru of dreamweaver helper or something...? sort of
like how they do it in yahoo answers

You can't do an "or" statement in URL variables. The query
string (after
the question mark) is a series of name/value pairs separated
by ampersands.

It's the script inside the web page that decides what to do
with the
variables.

Active Content Extension w/ URL Variables

Hi,
I am using the Flash Active Content extension and I need my
.swf to get a variable dynamically from my URL - how do I do
this?

I am using the Flash Active Content extension - for more
info:
http://www.adobe.com/go/7c29e252
This extension is a workaround so the user does not have to
click in the flash area to activate it for use, due to the IE
Active Content Update. It uses an external .js file to embed the
.swf file.
What I am asking is if my URL variable changes from
"www.website.com/index.php?myURL=red" to
"www.website.com/index.php?myURL=blue", how do I get the PHP to get
that information?

Defining a spry data set from a url variable

I am developing a family web site that, among other things, uses a single 'recipe' page to display recipes from different xml files as called by a url variable (e.g. ?xmlFile="{url}"&recipeName="{name}") from a summary page. I can get the recipe name to reproduce using a $_GET php function, but I cannot establish the data set that way. How can I define the data set from the incoming URL variable? The necessary files are:
The starting point from which I send the selected URL variable (use the scampi recipe) http://ebogott.com/recipeBox.php.
The file that is generated is http://ebogott.com/recipe.php?XMLfile=GrilledScampiOnAngelHair.xml&recipeName=Grilled%20Sh rimp%20Scampi%20on%20Angel%20Hair%20Pasta
This methodology will allow me a number of cascading selections. I know this is not unique. I just haven't figured it out.

Unable to get URL Variable

I've seen many posts about URL Variables, and I've tried implementing the solutions, but nothing seems to be working, so I'm hoping that someone out there might be able to help me with my situation.
I have built a JSP page in JDeveloper. The page must identify the visitor using an id (passed as a url variable) as well as an account_id entered by the user on the page. I've created a procedure in my ModuleImpl.java file that receives both the url variable and account_id and then calls a pl/sql transaction I've created in the database.
Thing is, if I take the procedure, which I've allowed to be shared to the Client interface, and plop it on my JSP Page, I get two inputs, one for the account_id and one for the url variable, meaning the user has to enter the url variable in the field for the procedure to work.
I've tried modifying the value of the field and setting it equal to #{param.id}, but when I run the page, the input becomes a display field and is not sent to my java procedure. I've also tried the FacesContext way of getting a url parameter, but I can't get that to work in my java file.
What I would like to have (or at least what my intensions were when I started this project) is to have the url variable field be hidden and automatically populated with the url variable so that when the customer enters their account_id and clicks submit, both the account_id and url variable are passed.
Any idea on how to implement something like this?

You can try setting the value of the parameter in the
pagedef.xml file for your page directly using
expression language.Thanks for your reply! I did that, or at least I think I did. Here is the NameData tag in my pagedef.xml file:
<NamedData NDName="web_hash" NDType="java.lang.String"
NDValue="${bindings.save_new_password_web_hash}"/>
what I've tried doing, is changing the NDValue to the three values below, all of which didn't work (returned null):
NDValue ="${param.id}"
NDValue ="#{param.id}"
NDValue ="${facesContext.externalContext.requestParameterMap['id']}"
is there a different expression I should be using?
Also, I will take a look at the solution you likend to.

Any way to add a URL variable to EVERY SINGLE url in the site, all at once?

Hi,
I'm managing a web application, and we're looking at changing from using cookies, to passing session variables in every HTTP request to maintain session information.
So basically, I have a variable that needs to be appended to every single URL in the entire site - not just in links, but in cflocation tags etc.
Is there any way to just ADD information to the end of every URL, without otherwise CHANGING anything in that URL?
This site is hand-coded, but I have access to Dreamweaver CS3, so I thought I'd ask if it was possible - it'd save me a bunch of time!
Thanks,
Joe

Hi, thanks for the reply.
I am familiar with DW's basic find/replace functions, but I don't think it'll work in this case.
See, the URL's are almost ALL unique. Many of them already include other URL variables... This is a pretty server-intensive web application, with a lot of data manipulation and database reads/writes.
So I was hoping for a function that could find all URL's (it could just look for a string containing .cfm), and append the code to include one more variable to the URL.
I see there's a way to use a regex in the find/replace tool, but it'd probably take me as long to write and debug the regex as it'd take to manually mod the URLs lol.
Thanks for any ideas!

Using URL variable to set initialy selected ds row

Hello everyone,
Could anybody suggest a solution or point me to a working
demo of a script that processes a URL variable and set the current
row accordingly. I am trying to pass a @id of a particlar row in a
URL variable to identify a particluar row, I want to be selected
initially.
Thanks,
Nick

Hy guys,
Just figured it out myself. Here is the script:
<script type="text/javascript">
// define your datasource. I have called it dsGallery. This
name is used later in the script a few times
var dsGallery = new Spry.Data.XMLDataSet("gallery.xml",
"/gallery/photos/photo");
dsGallery.addObserver({ onPostLoad: function(ds, type) {
var strReturn = "";
var strHref = window.location.href;
if ( strHref.indexOf("?") > -1 ){
var strQueryString =
strHref.substr(strHref.indexOf("?")).toLowerCase();
var aQueryString = strQueryString.split("&");
for ( var iParam = 0; iParam < aQueryString.length;
iParam++ ){
if (
aQueryString[iParam].indexOf('id' + "=") > -1 ){
var aParam = aQueryString[iParam].split("=");
strReturn = aParam[1];
// look if a row with a matching @id is present in the
datasource
var row = dsGallery.findRowsWithColumnValues({"@id":
strReturn}, true);
// If we have a matching row, make it the current row for the
data set.
if (row) dsGallery.setCurrentRow(row.ds_RowID);
break;
</script>
Thanks to the folks whose scrips were really helfull in
building this one.
