I want to create a configurable select list in forms.To achieve this what I did is I have created a text area, in that I will enter values like:


So, in form select options I have to use these values in a dropdown list. How can I achieve that. I am getting this text area data in form like below.Here I am getting data, but not displaying in the options.

$entityoptions = variable_get('entitydropdown'); 

I am getting the values as it is, but am not getting how can I assign these values to #options. I did like below but its not displaying the values.

'#options' => $entityoptions,

Please help me to identify, where I am doing wrong. Thanks in advance.

  • You can already make select lists with Drupal, out of the box. May we ask why you're trying to make something Drupal already does?

  • But I need conifgurable values. So only I am saving values in one admin panel text area, SO that whenever I want I can change values, and dynamicaly those values should display in form select options.

  • Can you help me that, how can I retrieve data from text area in an array. I used explode('|', $entityoptions ); It works but,its failing to identify end of the line and next line.

As requested in the comments, in answer format:

  1. Use the explode() function on your string
  2. Loop through the results and split each entry
  3. Add the result to the options array you feed to the select box


$options = array();
$lines = explode(PHP_EOL, $entityoptions);
foreach($lines as $line) {
  $line = explode('|', $line);
  $options[$line[0]] = $line[1];
