Hello

I have seen the documentation you provide
http://www.gravityhelp.com/documentation/page/Dynamically_Populating_Drop_Down_Fields
and also
http://www.gravityhelp.com/documentation/page/Gform_pre_render

but when implementing in my site I get a blank page when I try the view the resulting form. Also when implementing the code of the second link above and try to update the post I also get a blank one with this url http://mysite.com/wp-admin/post.php

Before going deeper, are your samples still valide? just in case they are not anymore with las wp versions.

Thanks

If you get a blank page, it is likely you are experiencing a 500 Internal Server error. Please check your server's PHP or Apache error logs to see what the error is.

If you're using PHP 5.3, it's possible this notation will not work for you, and will throw an error:
```
[php]
// this code can throw an error
foreach($form["fields"] as &$field) {

// you might need to change it to this
// drop the ampersand
foreach($form["fields"] as $field) {
```

Ok, with that now the page is displayed but the dropdown is not populated.
I just copied this code
http://www.gravityhelp.com/documentation/page/Dynamically_Populating_Drop_Down_Fields

and checked this advanced option:
Allow field to be populated dynamically(?)

Should I do something special with "choices" in the form? Do I leave the default First, second and third choice?

I correctly write the css class to be checked.

Thanks

You have not given us enough information to help you yet.

What are you trying to populate the dropdown with? What code are you using exactly to populate the dropdown? Please post the code at pastebin.com or pastie.org.

Please share a URL to the page on your site where the form is embedded if it will help us.

Thank you.

Hello

here you have my code
http://pastebin.com/5ugJcxFT

I am testing it locally so there is no page to check it. If with taht code is not enough to figure out a solution I will try to do it live.

Thanks

On line 12 of your paste, can you place a debug statement to dump the $posts array (use var_dump or print_r). We need to see what $posts contains at that point before trying to populate your drop down.
