[SOLVED] retaining <select> form value after refresh

[unsider]

I've alowed my users to "preview" the article their creating, check that the WYM editor is functioning properly, but in order to place the article into a category I'm using a <select> form, and the page is refreshed upon previewing the creation, and the select form value is reset.

 

So I'm curious, is it possible to store the selected option in a session value, or would this involve using JS client side to hold the value. Maybe a mixture of both?

 

Thanks.

Let's say you're using POST to send the select data to the verification page.

 

What I do is (this is if the 'values' in your <options> are integers, but you could work around that if you're doing something else):

 

$selected = array();
for ($i = 0; $i < $numberofvaluesinselect; $i++) {
if ($i == $_POST['selectname'])
	$selected[$i] = ' selected';
else
	$selected[$i] = '';
}

// Stuff happens, we close PHP with ?> and we're printing the form again:

<select name="bla">
<option value="0" <?php echo $selected[0]; ?>>Option 0</option>
<option value="1" <?php echo $selected[1]; ?>>Option 1</option>
<option value="2" <?php echo $selected[2]; ?>>Option 2</option>
<!-- etc -->
</select>

 

So, if the value was selected from last time, the <option> of that value says 'selected', otherwise nothing.
