I've been fighting this one for seven hours straight, and have read every bit of documentation I can find. I *know* I'm overlooking something really simple. Please help! Here's what I need to do in the edit handling of a custom node: 1. On initial entry to node/#/edit, I need to load values from the database using hook_load() and stuff them into the $node object. This is working perfectly, and the value from the databse loads into the visible form and displays correctly. 2. When a preview is submitted, I need to take the value that comes from $_POST and edit it before the form is generated. This is where things are breaking down. I can "validate" the value, issuing errors if I don't like it, but I can't seem to *change* it under programmatic control. I have tried changing $node->(my custom field) in nodeapi:validate, and in nodeapi:prepare, and even in hook_form. The thing is, I'm putting the modified value into the '#default_value' element of the appropriate part of $form, but somehow it's getting set back to the original $_POST contents from that field, between when I build the $form array and when that array is turned into HTML. I've been all over the code, but I can't seem to find where that's happening. Can someone help? Thanks!
