Update Select via Query String was created by igcorreia

Hello,
I have this link, this is a REGULAR form submission in FC Front end:

Code:

/index.php?option=com_flexicontent&view=items&layout=form&typeid=1&Itemid=1?carselected=toyota

I have created a SELECT FC FIELD that list a few cars, this list is present in FC Front End Submission View:

Code:

<select id="cars" class=" required" name="cars">
<option selected="selected" value="">Please Select</option>
<option value="1">Toyota</option>
<option value="2">Mercedes</option>
<option value="3">Bmw</option>
</select>

I want to _GET the value from the query string:

Code:

carselected=toyota

And set the option Toyota as default:

Code:

<select id="cars" class=" required" name="cars">
<option value="" >Please Select</option>
<option  selected="selected" value="1">Toyota</option>
<option value="2">Mercedes</option>
<option value="3">Bmw</option>
</select>

Can anyone help? This is awesome but I don't know where to start.

It could be in the FC SELECT PLUGIN or in the form view ether way I don't know more than this.

You could put some PHP code in any PHP file e.g. your joomla template, that adds some js JQuery code to use URL variable to set the required field:

But you must pass the id of the car instead of the name:

/index.php?option=com_flexicontent&view=items&layout=form&typeid=1&Itemid=1?carselected=4

(NOTE: you convert toyota to 4, but you would need a db query)

Code:

<?php
$document = & JFactory::getDocument();

$option = JRequest::getVar('option');
$view = JRequest::getVar('option');
$layout = JRequest::getVar('layout');

$carselected = JRequest::getVar('carselected');

if ($option=='com_flexicontent' && $view='items' && $layout=='form' && $carselected) {
	$js = "
		window.addEvent('domready', function() {
  		$('cars').val('".$carselected."');
		}
	";
	$document->addScriptDeclaration($js);
}
?>
