TEMA:

Hello,

Could someone please help me out with a problem I am having trouble solving?

I am passing a variable through my URL to my forms page, such as:

mywebsite.com/form?var=Option1

And what I would like to do is set my select list field to be pre-set at 'Option1'. I have read through the forums and knowledge base and know that I have to put the following code into Form Manager > go to your form > properties > more options > form pieces > before form > custom:

$this->execPieceByName('ff_InitLib');
//fetch the url code
$mycode= JRequest::getVar('var');

//assign it to the form element
ff_setValue('dropdownlist' , $mycode );

The problem is it does not set the 'Option1' value to 'selected' and show it as the selected option in the dropdown box. It does work when I try to set a text field to the value passed but not a select list. Does anyone know how I can do this?

Thanks in advanced!

Nancy

Hello aictcnm,

this is a little bit more complicated with select-lists.

Please have a look at this small sampleform. Possible Parameter values:
&var=1
&var=2
&var=3

You can find the code in the Before Form Piece and in the Init script of the textfield.

You can change the textfield to a hidden Input element of course.

7 years later I am at the same point:
I need to set a dynamic default/selected on a select list (not dynamic) depending on a variable ($_SERVER[ 'HTTP_REFERER' ]) - but I can't import the example provided by @crisal in my BF-Installation (1.9.1 Stable (941)).

Does anybody has an installable export of such an example?

Read and adapt JS-/PHP-Code is not that problem, if the example does not perfect matching the needs

Kind regards
Roger

Hi,

here is this example:


Please download->unzip->and install it (BF->Configuration->Package Installer->select this xml file->Install Package).

After that you will find form in Manage forms inside Package QuickModeForms
