You need to declare that your global variable is available inside the hooked function, like so: <pre><code>[php] add_filter('gform_field_value_image_filename', 'get_filename'); function get_filename($value){ global $image; ...</code></pre> Now it will be available in the function per your second two examples. ironsoup on "Using gform_field_value with a global array?" https://legacy.forums.gravityhelp.com/topic/using-gform_field_value-with-a-global-array#post-48854 Thu, 09 Feb 2012 14:43:32 +0000 ironsoup 48854@https://legacy.forums.gravityhelp.com/ I'm having similar frustrations...hope someone can shed some light on this topic! tdiaz1 on "Using gform_field_value with a global array?" https://legacy.forums.gravityhelp.com/topic/using-gform_field_value-with-a-global-array#post-48274 Fri, 03 Feb 2012 12:39:54 +0000 tdiaz1 48274@https://legacy.forums.gravityhelp.com/ I posted a similar thread, but I'll take a different approach: I've got various arrays available within my template, and want to put some of that data into the form being integrated into that same page: Viewing raw <?php echo $image->filename ?> <?php echo $iptc['location'] ?> So this works: <pre><code><?php add_filter('gform_field_value_image_filename', 'get_filename'); function get_filename($value){$variable = "FileName" ;return (string) $variable; } ?> <?php echo $image->filename ?> <?php gravity_form(1, false, false, false, '', false); ?></code></pre> This however, will not: (I get nothing) <pre><code><?php add_filter('gform_field_value_image_filename', 'get_filename'); function get_filename($value){$variable = $image->filename ;return (string) $variable; } ?> <?php echo $image->filename ?> <?php gravity_form(1, false, false, false, '', false); ?></code></pre> Or simply this doesn't work. (I get nothing) <pre><code><?php add_filter('gform_field_value_image_filename', 'get_filename'); function get_filename($value) ; return $image->filename; ?> <?php echo $image->filename ?> <?php gravity_form(1, false, false, false, '', false); ?></code></pre> The instances of the plain echo work just fine. So it's available "right there". How do I get that information *into* the "get_filename" loop? It's obviously global. Otherwise, I have no clue what the purpose of this routine to pre-load data via the function is for- if all it works is with a hard coded "return "this data" because you can do that directly in Gravity Forms.
