Hi there,
Got a little question for all the modx'ers out there.
I want to achieve the following and I'm not sure which way to go, all in Revo 2.X
In backoffice I want a Template var with checkbox inputs, so the admin of the site can select colors, no problem there, just choose the input controller to be a checkbox and the options in this format, option1==green||option2==red,...
So far so good. In the template that builds the page I want to display the selected colors in a drop down menu. As part of a form.
Something like this:
<select name="select" id="select">
<option value="green">green</option>
<option value="red">red</option>
</select>
So when admin selects more or less colors, the dropbox has to choose the right colors.
How to I manage this? Probably writing a snippet of my own, but I'm kinda lost there

try:
[[!prepareSelect? &values=`[[*colorsTV]]` &name=`color`]]
with a snippet like that:
<?php
$values = str_replace(',','||',$values);//in case the values are commaseparated, convert the delimiters to doublepipes
$values = explode('||', $values);
$output = '';
if (count($values) > 0) {
$output = '<select name="'.$name.'" id="'.$name.'">';
foreach ($values as $value) {
$selected = $_REQUEST[$name] == $value ? 'selected="selected"' : '';
$output .= '<option ' . $selected . ' value="' . $value . '">' . $value . '</option>';
}
$output .= '</select>';
}
return $output;
