#13905 — html php form second drop down select dependant list to keep selected value

Hi,

Is there a way to have the second drop down select list to keep the selected value after user hits submit?

<select class="select_Y" name="FLexA" id="LexikA">
	<option value="0" >Please choose a context...</option>
	<option value="1" <?php if (@$_POST['FLexA']==1) {echo "selected='selected'"; } ?> >Human nature , Health, Ethic, Religion...</option>
</select>

<select class="select_Y" name="FLexB" id="LexikB" jqsd:depends_on="LexikA" jqsd:hide_mode="disable">
	<option value="0" rel="0" >Please choose...</option>
	<option value="2" rel="1" <?php if (@$_POST['FLexB']==2) {echo "selected='selected'"; } ?> >Business, Law, Financezzz...</option>	
	<option value="3" rel="1" <?php if (@$_POST['FLexB']==3) {echo "selected='selected'"; } ?> >Sport, competition...</option>
</select>

Thansk,
Pascal

The best way to save values across pages is in the $_SESSION superglobal.

I was just looking at this... using session_start and $_SESSION array...

Would it goes as:
document.getElementById("MyDropDown").value = '<?php echo $_SESSION['MyStoredValue']; ?>'

or

jQuery('#MyDropDown').val('<?php echo $_SESSION['MyStoredValue']; ?>');

thanks,
Pascal

Pascal,

Pretty much.  Just a couple of things to remember:

session_start() must be called before ANY output to the client.  This
includes <!DOCTYPE...>, <HEAD...> and even blank space.

This must be done on EVERY page which uses $_SESSION values.

And, of course, you must store the value in the $_SESSION, also.

And you should check to see if the value is set before using it (i.e.
the first time through it may not be set); if not,  you should supply a
default value.

As for whether your jQuery code will work or not - try a javascript
newsgroup.  But the PHP code looks OK.
