Sorry if I misunderstand the problem, but could you not use drupal_map_assoc right before you return your array?<br><br>$arr = explode("\n", $node->body);<br>return drupal_map_assoc($arr);<br><br><div class="gmail_quote">

<br><b>Problem:</b> What gets stored in the database is the integer key from the indexed array created by explode(). The data integrity is thus completely dependent upon the order of the items listed. I don't want that. I want people entering the data to be able to change the order. <i>I want an associative array in which the keys and labels are the same.</i><br>
<br>Note that if, via the field configuration UI, I simply list the values in the allowed values box... Drupal turns that list into an associative array in which the keys and values are the same. Exactly what I want! But I don't know how to create that for the custom PHP value set. I'm putting the code here from CCK where this happens. I don't quite get it.<br>
<br>Any hints would be most appreciated,<br><br>Shai<br><br><font face="'courier new', monospace">/**<br> * Create an array of the allowed values for this field.<br> *<br> * Used by number and text fields, expects to find either<br>
