Hi,

I can't figure out, how to display all input values for specific TV (type single listbox).

My TV input is:

a||b||c||d||e

Now I need to display all the values (not the selected / assigned to template) as a dropdown menu (which isn't the problem yet).

☆ A M B ☆

The modTemplateVar object has a getInputOptions method that you should be able to use in a snippet. Use the $modx->getObject('modTemplateVar',$criteria) function to get the particular TV object you're interested in. Perhaps something like this would give you an array of options to work with:

$myTV = $modx->getObject('modTemplateVar', $tvID);
$options = $myTV->getInputOptions();

Thank you

I wasn't aware of the modTemplateVar object.

Finally i made the script as following:

$tvname = $scriptProperties['tvname'];
$output = "";

$tv = $modx->getObject('modTemplateVar',array('name'=>$tvname));
 
$elements = $tv->get('elements');
$items = explode('||', $elements);

foreach ($items as $item) {
  $output .= "<option>$item</option>";
}

return $output;

Unfortunately, this

$options = $myTV->getInputOptions();

gave me an error but after more searching I found the correct way

The

elements

is the actual column name in

modx_site_tmplvars

, holding all values of specified TV.
