Best way to validate a name field... (PHP)

Hi,
I'm trying to improve my contact form and as it is now I do
the
following with the first last name input field....
I limit the input (40 characters)
I only allow one space between first and lastname
I strip and add slashes
I'm not sure the "one space" thing is good. What are your
opinions on
this? How do you do it?
Is this the best way to do it or is there something very
clever I missed?

Validate, but don't over-validate. There are some things you
can fix
silently, for example multiple spaces - just replace them
with a single
one and move on. Length limit is OK if you want to insert the
data into
a database.
Slashes - you should remove them if magic quotes are enabled
(check with
get_magic_quotes_gpc()) and then use an appropriate escaping
function if
necessary, for example mysql_real_escape_string(),
htmlspecialchars() or
whatever. It just depends on what you want to do with the
data.

What is the best way to clone a form field in BC

Hi,
What is the best way to clone a form field in BC. I tried using jquery .clone. It works fine on other forms for me but not on the BC forms, why? is it just me? Any help would be great. Thanks

I mean, duplicate a field with the click of a button.
I think this should work, but it's not and I am linked to the jquery library in the head of my page.

Any way to validate the Mandatory field in the XML file

Hi,
Is there any way to validate the Mandatory field in the XML file. I created an xml type table xml_validate based on the schema and insert the XML files with statement.
INSERT INTO xml_validate(warehouse_id,xml_file_name,warehouse_spec)
Values (agreementid,p_filename,XMLTYPE.createXML(l_clob));
It is validating the data types, extra tags etc but not validating the missing of the manadatory tag/value.
Thanks in advance
Rizly

Hi Ants,
Yes, I was not doing the strict validation, after searching the forum i understood that was the reason. So i did this way,
begin
for x in (select myColumn from myTable where WAREHOUSE_ID=41) loop
x.myColumn .schemaValidate();
end loop;
end;
The out put is:
ORA-31154: invalid XML document
ORA-19202: Error occurred in XML processing
LSX-00011: internal error: LsxvPushCandidate array overflow
ORA-06512: at "SYS.XMLTYPE", line 345
ORA-06512: at line 3
My i know more information about this error, especially
LSX-00011: internal error: LsxvPushCandidate array overflow
Thanks in advance

Best way to validate and xml file against a schema?

As the subject states, I want to validate my xml file against a given schema....
Currently my code looks like this:
InputSource ipSource = new InputSource(new ByteArrayInputStream(bytesData)); // my xml file
DOMParser parser = new DOMParser();
parser.parse(ipSource);
Document doc = parser.getDocument();
I see that there is a setFeature method on DomParser.... but from what I read that doesnt support
xml schema's, just DTD's. So what is the best way to validate with schema's?
Any help would be appreciated

This is the other way I tried doing it.... the problem with this way is I am building my xml file through DOM
operations... and I haven't figured out how to add the schema line to the xml file through DOM manipulations.
Has anyone done this bofore?
try
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
     factory.setNamespaceAware(false);
     factory.setValidating(true);
     InputSource ipSource = new InputSource(new ByteArrayInputStream(bytesData));
     DocumentBuilder builder = factory.newDocumentBuilder();
     doc      = builder.parse(ipSource);
     return doc;
catch(Throwable t)
     System.out.println("parse error: " +t);
return doc;

What is the best way to validate?

This image is a template Im using to create an expense form.
http://img160.imageshack.us/img160/963/form25vp.jpg
I have a specials item section which is just totaled from all the Special Items fields.
Was able to create a totals script to but could not get it to leave the field blank. Thanks to Justin Klei using this script it totals without a problem.
This has been placed it the Calculate section of the Total field.
var totalval = form1.costs.spei1.rawValue + form1.costs.spei2.rawValue;
if (totalval == 0 || totalval == null || totalval == "")
this.rawValue = "";
else
this.rawValue = totalval;
If the user types $12.00 into the Special Items 1 field they then are able to transfer this to the main table by clicking on any of the Special column fields. In each field Ive got the following script that will allow the user to click on any of the Special column fields and only apply the total once. If the user clicks on the Tuesday field and then decides to move the total to Sunday all they have to do is click on the Sunday field.
This have been placed in the mouse down event (will create a transparent button later).
if (this.rawValue)
sunspe.rawValue = ""
} else {
sunspe.rawValue = spetot.rawValue
monspe.rawValue = ""
tuespe.rawValue = ""
wedspe.rawValue = ""
thuspe.rawValue = ""
frispe.rawValue = ""
satspe.rawValue = ""
Ive just reused the script for each field and moved the spetot.rawValue to the appropriate day.
Here is my question.
If the user types a figure in Special Items 1 and then applies that figure to the Special column and then decides to add another figure to Special Items 2, what is the best what to validate the Special column?
Would having a message pop up be the best?
This has been placed in the Validate section of the Total field.
if (spetot.rawValue != sunc1.rawValue)
app.alert("There has been a change to the Special Item Total \n Please update the Special column.");
Is it possible for the form to automatically update the figure if it has been applied to the Special column?
The problem I have with the message currently is obviously it pops up every time you add a figure into the Special Items. Is there a way to compare only if there is a figure in the field?
Any suggestions would be appricated.

Hi,
it was the same i built my small proj with the user authentication with SQL server and JSP.
u should first create a table with 2 fields "user" and "pass"
in ur jsp the name of the textboxes for the user and pass should b the same .

u need 2 write some connections say "
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("user", "Pass");
i'll post u the entire code soon.

Best way to validate multiple entity objects with each other

I have the following scenario.
There is one entity object with the following fields.
Name
Start Date
End Date
My requirement is to validate the dates in the entity do not overlap.
What is the best way to achieve the same.
This validation should be fired when we commit, since the user should be allowed to change the dates freely between entities.(Validation should not kick off when the current row changes)
Thanks

For this to achieve there is a concept called Effective Dated Entity Objects in Oracle ADF.
Official ADF Documentation: http://docs.oracle.com/cd/E37975_01/web.111240/e16182/bcentities.htm#ADFFD20110

WAD - Best way to layout master data fields for a single record

I am creating an employee profile which will be fed from various InfoProviders in BI. I am going to lay it out so that there is a master data section at the top and then below there will be various histories (salary, job, etc) and everything will be populated by the value of a single variable.
The question I have is what is the best way to lay out about 20 master data fields in the top section and have it look nice? My guess (and I am not fond of the tedium) is to create a bound text for each of them and bind it to the appropriate characteristic. Then just have the variable setting affect all of them.
Anyone have any other ideas?

Hello,
you can use the interface command:
storm-control unicast level 10.00
or
storm-control unicast bps 10000000
The first command will limit bandwidth to 10% of what is available, the second will limit bandwidth to 10Mbps, effectively achieving the same thing.
Check this link to the relevant configuration reference:

What is the best way to pass a var from php to a swf to swf

Hi,
Whats the best most correct or professional (less chances of error or most efficient) way of sending a var from php to a swf container and then to a swf that is loaded with the loader class from the container???
Thanks

Hi Kglad thanks for the answer,
Yes using AS3, I think I didnt give u enough info though.
The thing is the php file is actually the index file which has the first swf lets call it conatiner.swf embeded and conatiner.swf then calls the other swf lets call it main.swf by using URLloader. So I dont think I can user URLloader on the index.php file, and I cant put the code in another .php file and call it because I need data from the index.php file specifically.
Any ideas?
I know I can use flash vars for the first step of the index.php to container.swf but im trying to avoid it cause im not so familiar with it or embedding and theres two diferent embedding methods im using depending on the site and im probably going to have to change them again later on cause im still having an issue.
Thanks

Best way to map CLOB database fields?

I ran into a problem mapping CLOB fields a couple of months ago and couldn't find an easy answer to the problem. I got sidetracked and now find myself back at the same point...
What is the best practice for mapping CLOB database fields in the mapping workbench? Do you map them as serialized (as a note I've got here) or can someone point me in the proper direction please? I've got everything else functioning properly, but I left my CLOB fields out of my mapping because they were giving me such trouble. Now, I need to get back to that specific area.
~ Tiffani

Hi Tiffani,
SerializedObjectMapping is generally used to map a multimedia object (for example image)to a BLOB field. For CLOB, I use simple direct-to-field mapping, and TopLink conversion manager will handle the read/write from the object String/Char[] to CLOB.

Best way to validate currency field based on two picklists

Hi,
Im having a great deal of trouble creating validation for the following statement:
If (Task type =”Call” or “Callback”) and (‘Outcome Category’ is “In Progress” or “Tried and Failed to Save” or “Saved”) then (‘Total Value of Policy’ must be > 0)
Both task type and outcome category are picklist items.
What is the easiest way for me to do this? Ive created something horribly complex which only works when I first create the record (possibly because of the use of FieldValue rather than stored values). Ive seen people use the NOT function before to do this - could this be an option?! Ive had no luck with anything Ive tried so far.
My current expression is as follows:
(FieldValue('<cTotal_Value_of_Policy_ITAG>') > 0
AND FieldValue('<Type>') <> LookupValue("TODO_TYPE", "Investigation") - - Because call or callback are the only other options in the list.
AND (FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "In progress")
OR FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Tried & failed to save")
OR FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Saved")))
OR FieldValue('<Type>') = LookupValue("TODO_TYPE", "Investigation")
OR (FieldValue('<Type>') = LookupValue("TODO_TYPE", "Call")
AND (FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "In progress")
AND FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Tried & failed to save")
AND FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Saved")))
Sorry for including this confusing chunk of code, but I think it explains how more complex i have made this than i probably need to!!
Any help would be greatly appreciated as this is quite an urgent issue..
Many Thanks
AJ

Anon,
In your edit form, create two hidden items p10_ha, p10_hb (for e.g.) Make the default values for these items as values of p10_item_a and p10_item_b respectively. So when you are processing the update, you have old values in hidden items and new values in p10_item_a and b.
Now create 'after submit' pl/sql computation and put similar code
if p10_ha !=1 and p10_hb !=1 then
    if p10_item_a = 1 and p10_item_b = 1 then
    -- your business logic here
   :p_date_item := sysdate;
   end if;
end if;Hope it helps
Cheers

Best way to retrieve/store date Flex PHP MySQL?

Hi All,
I have a question about storing/retrieving a date-field from the MySQL database, using Flash Builder 2 & Zend AMF.
This is as much as I know:
MySQL Database stores date in this format: yyyy-mm-dd hh:mm:ss
And Flex will not recognise that as a "date", instead it will suggest this value is an "object".
With "Configure return type", I can manually set this field to "date", but it will not work retrieving of updating the date as MySQL will not understand the standard date-format it'll receive,
I guess, the best solution would be if I could tell the MySQL Server how the standard date-format should be, but I have not found this option. Can anyone confirm this?
The remaining options are:
Format the date in the SQL-query
Format the date in the PHP-function sending/retrieving
Format the date in Flex, befor assigning it to a date-field...
Can someone tell me the BEST practice to handle date-objects? I guess it's the date_format function in MySQL....
I'm trying to build an app with over 3200 fields, shared over 60 tables, of which many are date-fields.
Would be awesome if I could just use SELECT * FROM myTable, and all would be fine with date-fields and all...
Any tips?

I'm confused. This is what I have:
On my MySQL database, I've created a VIEW with the query that I need. I thought it'd generally be efficient to create views for every 'Form' that I need.
This is my VIEW v_person
SELECT p.`person_id`, p.`name`, p.`lastname`, DATE_FORMAT(p.`birthdate`,'%d/%m/%Y %r') as birthdate
FROM person p
Now I have a simple table v_person returning
person_id
name
lastname
birthdate
0
John
Doe
null
1

"Great! Now I can set up my query once, returning the date in whatever format Flex likes."
Not.
This is the standard generated PHP function to get information by ID. This works fine.
     public function getV_personByID($itemID) {
          $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename where person_id=?");
          $this->throwExceptionOnError();
          mysqli_bind_param($stmt, 'i', $itemID);
          $this->throwExceptionOnError();
          mysqli_stmt_execute($stmt);
          $this->throwExceptionOnError();
          mysqli_stmt_bind_result($stmt, $row->person_id, $row->name, $row->lastname, $row->birthdate);
          if(mysqli_stmt_fetch($stmt)) {
               return $row;
          } else {
               return null;
This is the standard generated Form in Flex:
One note to make when using RETURN TYPE,
is that in when I use person_id=0 , I can change "birthdate type" from OBJECT to DATE, because date is null.
When I use person_id=1 , I CAN'T change "birthdate type" as it defaults to "STRING".
Since I want to use a dateField in my Form, I changed birthdate type to "DATE". (Even though I now understand that return type IS in fact a string)

TypeError: Error #1034: Type Coercion failed: cannot convert "10/21/1984 12:00:00 AM" to Date.

Somehow SOMETHING wants to convert "10/21/1984 12:00:00 AM" to Date.
Where does it fail? I feel like I'm SO close, but making a faceplant right before the finish.
ok.
I'm by no means an expert, so let me know if I'm doing something wrong, but this is how I'd expect it to work.
Can someone tell me how I should use a dateField instead? Where should I make the stringToDate and dateToString conversion?

Best Way to Validate a Path

I am writing a cross platform app that contains file path references. I would like to validate these, but since they may not exist, I can't just use a File object.
Has anyone had experience with this problem? I wanted to see if there is a better way than coming up with a regex for each platform, although, if someone has done this using regex, I would love to see them[the regexs];)

I want to check for a valid path (ie no characters such as ^&*(), etc) whether or not it exists. For example, if I do a File.exists() on the following path: c:\window$%\stuf# - I will get back false. If I do the same thing on c:\windows\whatever, I still get back false, but it is a valid output path for my tool.

Best way to proceed with adding fields to SAP Customer Master

I want to add 4 new fields to tcodes VD01/VD02/VD03(Customer Master create/change/display).
These fields will be stored in a separate Z table (not in KNA1).
I see what I think is a possible answer in SPRO -> Logistics -> Business Partner -> Customers -> Control -> Develop Enhancements for Customer Master Data
would this be the most appropriate solution? Or would a BADI work? If so which one?
any other ideas?
thanks,
rp.

ok, i think i'm on the right track..
through spro, i've created a screen group (ZC) and assigned it Tab Page Label information such as screen number, Function code, and Description.
next, under BADI subscreens, i've created in implementation of CUSTOMER_ADD_DATA_CS called ZCUSTOMER_MASTER with screen Group ZC.
under interface, I dbl click GET_TAXI_SCREEN and enter the following code:
IF i_taxi_fcode = 'ZC'.
    e_screen = '1050'.
    e_program = 'SAPMZCRED_ALLOC'.
    e_headerscreen_layout = ' '.
ENDIF.
I then created screen 1050 in program SAPMZCRED_ALLOC with just 1 field as a test.
But, after everyting is activated, I don't see my new tab.
However, if I change the screen group to O0 (Additional Data, IS-OIL General) and my i_taxi_fcode check to O0, then run VD02, I do see my screen when I click the Additional Data, IS OIL General button in VD02.
So, it looks like I need to assign my screen group ZC to the tab strip in VD02.. can you tell where to do that?
