Description

Create an array of the allowed values for this field.

Used by number and text fields, expects to find either PHP code that will return the correct value, or a string with keys and labels separated with '|' and with each new value on its own line.

Code

<?php
function content_allowed_values($field) {
  static $allowed_values;

  if (isset($allowed_values[$field['field_name']])) {
    return $allowed_values[$field['field_name']];
  }

  $allowed_values[$field['field_name']] = array();

  if (isset($field['allowed_values_php'])) {
    ob_start();
    $result = eval($field['allowed_values_php']);
    if (is_array($result)) {
      $allowed_values[$field['field_name']] = $result;
    }
    ob_end_clean();
  }

  if (empty($allowed_values[$field['field_name']]) && isset($field['allowed_values'])) {
    $list = explode("\n", $field['allowed_values']);
    $list = array_map('trim', $list);
    $list = array_filter($list, 'strlen');
    foreach ($list as $opt) {
      // Sanitize the user input with a permissive filter.
      $opt = content_filter_xss($opt);
      if (strpos($opt, '|') !== FALSE) {
        list($key, $value) = explode('|', $opt);
        $allowed_values[$field['field_name']][$key] = (isset($value) && $value !=='') ? $value : $key;
      }
      else {
        $allowed_values[$field['field_name']][$opt] = $opt;
      }
    }
  }
  return $allowed_values[$field['field_name']];
}
