I have in form multiselect options list. The Form handles itself. I need, after then I press submit, the multiselect list is been already had with the selected options.
Chunk form:

<form method="post" action="[[~[[+id]]]]" >
	Product types:

	<select size="7" multiple="multiple" name="prod_type[]">
	    <option value="1" [[+prod_type:eq=`1`:then=`selected="selected"`:else=``]]>First</option>
	    <option value="2" [[+prod_type:eq=`2`:then=`selected="selected"`:else=``]]>Second</option>
	    <option value="3" [[+prod_type:eq=`3`:then=`selected="selected"`:else=``]]>Third</option>
	    <option value="4" [[+prod_type:eq=`4`:then=`selected="selected"`:else=``]]>Fourth</option>
	    <option value="5" [[+prod_type:eq=`5`:then=`selected="selected"`:else=``]]>Fifth</option>
	    <option value="6" [[+prod_type:eq=`6`:then=`selected="selected"`:else=``]]>Sixth</option>
	    <option value="7" [[+prod_type:eq=`7`:then=`selected="selected"`:else=``]]>Seventh</option>
	</select>
<input type=submit value=submit />
</form>

On snippet I tried to return selected options

$FormOutput = $modx->getChunk($formTpl, array(
'prod_type' => $_REQUEST['prod_type']
));

In a result I have array. But nothing is selected.

var_dump("$prod_type")
---
array(3) {
[0] => int(1)
[1] => int(2)
[2] => int(3) }

If I remove "[ ]" (name="prod_type") then i get ONE selected(last selected on form).

How I can return all selected options? [ed. note: alex_dutch last edited this post 12 years ago.]

hello
did you try using $_POST instead of $_REQUEST ?

var_dump("$prod_type")
--------------
array(3) {
[0] => int(1)
[1] => int(2)
[2] => int(3) }

You see, $_REQUEST works fine.

try to change your snippet like that:

$FormOutput = $modx->getChunk($formTpl, array(
'prod_type' => implode(',',$_REQUEST['prod_type'])
));

and the formitIsSelected-output-filter, which is included in the formit-package

-------------------------------

you can buy me a beer, if you like MIGX

Did you mean

/**
 * Custom output filter that returns checked="checked" if the value is set
 *
 * @var string $input
 * @var string $options
 * @package formit
 */
$output = ' ';
if ($input == $options) {
    $output = ' selected="selected"';
}
if (strpos($input,',') !== false) {
    $input = explode(',',$input);
    if (in_array($options,$input)) {
        $output = ' selected="selected"';
    }
}
return $output;

with output chunk

<option value="[[+value]]" [[+selected]]>[[+text]]</option>
