Problem extracting variables passed through a url

Hi I'm trying to pass two variables via a url which I can acheive, but I'm having trouble extracting the information when page refreshes.
This is the code I've used to pass the variables:_
<?php while ($row = mysql_fetch_assoc($result1)) { ?>
<a href="<?php echo $_SERVER['PHP_SELF'];?>?gallery_id=<?php echo $row['gallery_id']; ?>&year_id=<?php echo $row['year_id'];?>"><?php echo $row['name']; ?></a>
<?php } ?>
I'm able to acheive the my objective when on variable is passed using the following code:-
if (array_key_exists('gallery_id', $_GET)) {
$gallery_id = $_GET['gallery_id'];
My question is, how do I do this with two (or more) variables? I need to extract $year_id as well.
Thanks.

Thanks for the reply.
I get the following notice.
Notice: Unidentified index: gallery_id in ......
I'm trying to create a photo gallery that displays years at the top, the gallery names for the relevant year in the left hand pane and the relevant photos for a particular gallery in the right hand pane. I have nearly acheived the aim in that everything will initially display ok and when a different year is selected and the page reloads, it will list the galleries for that year and display the photos for the first gallery in the list.
The problem is that when a new gallery is selected I am able to pass the new gallery_id and the year_id when the page reloads, but I can't extract both results using If(array_key_exists and since the script needs both to function I'm a bit stuck.
What i really want to do is something like If(array_key_exists('year_id', 'gallery_id', $_GET)) {
but this won't work! Is it possible to do it this way or am I barking up the wrong tree?
Thanks.

Commas not correctly processed when values are passed through the URL!!!!!!

I think this is a bug. Any information about this will be greatly appreciated. Here's the scenario:
There's a single page with 2 regions. The first region contains a simple SQL report. The second region is and HTML region that contains text and date form elements. The SQL report has a column link "Edit" that when pressed it populates form elements in the HTML region. The population of the form elements is done by passing the column values of the select row as variables along the URL. The problem is that commas within column value text are processed as delimiters in the URL. From my understanding and documentation, variables and their values are supposed to look like this:
f?p=6000:6004:&APP_SESSION.::NO:6003:MY_ITEM1,MY_ITEM2,MY_ITEM3:1234,,5678
where MY_ITEM1 will be set to 1234, MY_ITEM2 will be set to null and MY_ITEM3 will be set to 5678 (The URL was copied directly from the Apex 3.0 documentation without modification).
However if the first value is text (lets say "some,thing") that contains a comma, then MY_ITEM1 will be set to the text preceding the comma in the first value (some), the MY_ITEM2 will be set to the text that comes after the comma in the first value (thing) NOT null and MY_ITEM3 will be set to null NOT 5678. Clearly, one would think that the comma in the first value should be escaped given that commas are used as delimiters of values in this URL scheme.
The URL looks like this:
f?p=6000:6004:&APP_SESSION.::NO:6003:MY_ITEM1,MY_ITEM2,MY_ITEM3:some%2Cthing%2C%2C5678
However the URL should look like this:
f?p=6000:6004:&APP_SESSION.::NO:6003:MY_ITEM1,MY_ITEM2,MY_ITEM3:some%2Cthing,,5678
where MY_ITEM1 is set to "some,thing", MY_ITEM2 is null and MY_ITEM3 is set to 5678
What does all this mean? This means that the escaped commas (%2C) are used as delimiters for the values. Additionally, any information that is passed that contains a comma will have it's comma escaped as well AND still considered as delimiters for values in the URL. Not to mention it's inconsistent with the official documentation.

Never mind... problem solved.
In the Apex docs says that you can embed commas if used within backslashes like: \123,45\.
So in order to pass text that has a comma through the URL, one must force Apex to code the URL like this (assuming that the text is coming from a report):
f?p=6000:6004:&APP_SESSION.::NO:6003:MY_ITEM1,MY_ITEM2,MY_ITEM3:\#A_COLUMN#\,,5678
Sorry... no bug. :)

One screen presentation problem on calls pass through cube

hello all,
may I have your advices about following problem;
this is flow diagram: cts codec (site A) -- >> cube -->> cts codec (site B)
if the codec in the site B is one screen as cts 1100 the presentation cant be shared bidirectional.
however if it is 3 screen as cts 3010 the presentation works fine.

hi
you have any string as
voice class sip-profiles 1
request INVITE peer-header sip Contact copy "(;video;audio;x-cisco-tip;x-cisco-multiple-screen=3)" u01
request INVITE sip-header Contact modify "$" "\u01"
change it with
request INVITE peer-header sip Contact copy "(;video;audio;x-cisco-tip;x-cisco-multiple-screen=*)" u03
request INVITE peer-header sip Contact copy "(;video;audio;x-cisco-tip;x-cisco-multiple-screen=(.*))" u03
request INVITE sip-header Contact modify "$" "\u03"
it will work.

Problem in sql pass through query

i am using the following query:

i am creating sqlPassthroughQuery but i am getting : Missing right parenthesis /Query not terminated properly exception
but the query is working without where clause and it is working also if i am not using query without parameters i.e.

Any pointers will be useful

Hi,
i used the query like this:
String query="Select * from table_name where col1 IN(?,?,?) and col2 = ?";
Object params[] = new Object[4];
params[0] = "val1";
params[1] = "val2";
params[2] = "val3";
params[3] = "val4";
Builder builder = (Builder)view.getQueryBuilder();
Query sqlQuery = builder.createSqlPassThroughQuery(query,params);
RepositoryItem[] items = view.executeQuery(sqlQuery);
This is just a basic example.You can get more info @ATG Repository Guide.

Pass through Url

I have a form where the user has an option of clicking submit
which submits the entire form or select a some abcdefg... which
submits the selected alpha and passes through a URL. The problem
now is that I want the user to select a radio button which tells me
the DB they want to search.
How wiould I pass the value of the radion button through url
to know the users seacr option?
I Need to put the value from the javascript in the URL and pass
the Value to the next form
<a href="/admin/Leadsresult.cfm?search=a" onclick="return
checkradio();">A</a>
This my script which I want to submit the value when user
clicks the above
function checkradio()
var check =document.b.criteria.value;
if (check ==1)
document.b.checkoption.value ='Cp';
else
document.b.checkoption.value ='Cb';
document.form.action="sult.cfm";
document.form.submit();*/
}

Oh, I missed that part. I'm not sure, but I don't think you
can use js to change variables in an anchor tag after the page has
been loaded. Have you considered using two links instead of one?

Passing Parameters through a URL to a Report..

I have noticed a lot of message about similar situations where people have had problems sending certain parameters through a URL.. so this is maybe something that's not possible.. but you if you dont ask then you dont know.
so..
We have a form that has search options in it
(its a customized form that replaces the customization bit that you get with a report -> .show_parms - just so we could do different things with it)
and one of the fields is a combobox populated by an LOV
- it has usernames in it
so when you search using a value in the combobox it will show all the records that that person has entered into the table..
however we are currently getting an error
Error: An unexpected error occurred: ORA-06502: PL/SQL: numeric or value error (WWV-16016)
this is the URL with the parameters
http://portal.somewhere.com/pls/portal30/foldername.RPT_Edit_Request_Old.show?p_arg_names=Request.RID&p_arg_values='||nRID||'&p_arg_names=Request.CID&p_arg_values='||nCID||'&p_arg_names=Request.ATID&p_arg_values='||nATID||'&p_arg_names=Request.REQUEST_NAME&p_arg_values='||nREQNM||'%&p_arg_names=_request_rid_cond&p_arg_values=%3D&p_arg_names=_request_cid_cond&p_arg_values=%3D&p_arg_names=_request_atid_cond&p_arg_values=%3D&p_arg_names=_request_request_name_cond&p_arg_values=LIKE';
when you remove the condition at the end
the report is displayed (but not customized obviously)
however you can see the value has been picked up from the combobox as it's in the URL in the address bar..
so that bit works fine
any thoughts/ideas/or even solutions! :) would be much appreciated
thanks
Richard

actually
nevermind
i got it to work without even knowing :)
the condition was causing the error
and adding a % after the value makes it work

Problem in passing Modified date through Go url

Hi All
I am trying to pass parameters through url to report.
Its working fine and passing row id of the record but when i try to pass modified date also, it takes me to no result view where i can see that value has been passed to report but the results are not filtered, instead no result view.
While passing date in url as parameter do we have extra consideration?
Anybody has faced smilar kind of scenario.

I am getting the following error when trying to pass modified date for oppty.

Passing variables through the URL String

I have a template and outside the basic html - all the content is grabbed from a db. I want to use 1 template to generate all of the other pages for the site. So basically, the only way to identify the page would be through the URL string.
So, something like -
www.mysite.com/template.jsp?page_section=aboutus&pageID=1
That string would query the database and output the content for page 1 of the about section.
Does this make sense and where would I start to learn how this is done?.
Again, I appreciate your help.
Mark

since database connections are costly affair i better use
jsp include tag ratter then getting dadta from database
assumming that u can devide your comman pages in 4 parts
just assume
top - logo
bottom - common links
center - data
left - menu
my jsp page would look like this (aboutus.jsp)
<%@ include file="top.html" %>
<%@ include file="left.html" %>
<%@ include file="aboustus.html" %>
<%@ include file="bottom.html" %>
2) disclaimer.jsp
<%@ include file="top.html" %>
<%@ include file="left.html" %>
<%@ include file="disclaimer.html" %>
<%@ include file="bottom.html" %>
this would reduce ur maintainnce as if u want to change top logo only top.html needs to be changed and it would affect in all pages

Passing 2 varibles through a URL

I don't know how to pass 2 variables through a URL. I am

It looks like you've got an extra set of quotes:
Take out the double quotes around #FORM.email#
I think that will solve the problem you are having with them
not showing up in the hidden form fields as well.

Passing prompt filters through an URL

My report has very long results table.
The user ask to have, instead of the table view (which sometimes crashes the browser), a way to execute the report and download it to xls.
I want to add section in the page, below the prompts, which will display the user a URL link to this report.
I've read that I can add in the end of the URL the xls format: https://myip/analytics/saw.dll?Go&Path=mypath&format=XLS
The issue is how to pass the presentation variables, which the report require.
For example, the report has filter:
day>@{p_day}
The p_day is populated by the prompt in the upper side of the page, when the URL link should appear.
I read the http://gerardnico.com/wiki/dat/obiee/url_filter, where he mentioned the case of 'Data Quality Metrics is prompt', but he didn't show the solution.
How can I pass the presentaiton variable value in the URL link?

Nir,
You should really search through the forums before posting your questions as this/similar question has been answers a few times.
But I'll take the points that you are going to award me though for providing you with the information and answer to your question. : )
Towards the bottom of this blog post you will find the answer you seek on how to pas the presentation variables in the URL,
http://www.iwarelogic.com/blog/integrating-oracle-obiee-content-using-go-url-850
Other Forum Threads:
Filter a dashboard prompt using GO URL
Code snippet from iwarelogic's blog post:
You can also pass Presentation variable in form @{variable_name} as a filter using GOURL.
And static variable in form VALUEOF(static_var_name)
Ex :
'<a href=http:// '||VALUEOF(domain_name)|| ' :9704/analytics/saw.dll?GO&path=/shared/Operational%20Reports/Scorecard&Options=d&Action=Navigate&P0=3&P1=eq&P2=%22Reporting%20Line%22.%22Reporting%20Line%20Domain%22&P3='||REPLACE("Reporting Line"."Reporting Line Domain",' ','%20')|| '&P4=eq&P5=Geography.Dominion&P6='||REPLACE('@{DominionPromptVar',' ','%20') ||'&P7=eq&P8=Geography.%22Country%20Name%22 &P9='||REPLACE('@{CountryNamePromptVar}',' ','%20') ||'>' || Link || ''
Note : Passing Parameters to the Report using GO URL is optional argument

Environment variables not passed through to player in flexunit 4.1.0-beta3

fyi, to get flexunit-4.1.0-beta3 FlexUnit4AntTasks invocation of flashplayer to not be rejected by the vncserver, i needed to modify the FlexUnitLauncher to pass through the environment variables to the command environment.
the reason this is required, i think, is the use of Runtime.exec() directly in CustomPlayerCommand -- in flexunit-4.0.0, the same function was accomplished using the ant executor, which does passthrough by default.
anyway, curious if anyone else has seen this issue, or if i'm doing something dumb.

ok. i went looking for a JIRA link somewhere around here and couldn't find it. do you have a URL handy?
there are a couple of other things too:
you probably want trustDirectory.mkdirs() rather than mkdir() in TrustFile.java
you probably want CustomPlayerCommand.setLocalTrusted() -- my player command isn't in the machine's path, but i still want to be able to touch the trust file. So I copied the trustFile.add() stuff from FlashPlayerCommand.launch() into CustomPlayerCommand.launch(). probably a better solution would be refactoring CustomPlayerCommand to be more like FlashPlayerCommand.
anyway, if you want patches, tell me where to put them and i'll post some.

Problem with "Pass Through Chapters" Theme

I was searching old post to get some help and this one help a little but there was still one problem unanswered. I have highlighted in red;
Nov 14, 2008 3:41 PM Re: Pass Through Theme problem
Re: Pass Through Theme problemin response to Glo H
My smaller text which appears in white says Scenes 1-6. The pass through text which is larger and has a different image in it says "Pass Through Chapters" and it rolls by while the smaller text stays put. I notice the image that shows through the pass through text is the same image I set on the main DVD screen. On that one my name of my disc roll past in giant see through letters. I like that but I just don't want that same effect on my chapters screens.
Can the image behind the rolling text be changed to the current window and not the main menu image?

Thanks for the tip and figured out to delete my "Scenes 1-6" that was automatically created when, in iMovie, I shared the movie to iDVD with chapters. The menu title text block doesn't like cut/paste and I had to retype the "Scenes 1-6" text for the motion/peek-through scrolling text to refresh.
Hmmm, but how tricky is that and where is it mentioned in the help/faq files etc?
cheers
