It is discussed int he documentation area for the function call here:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Embedding_A_Form" rel="nofollow">http://www.gravityhelp.com/documentation/page/Embedding_A_Form</a> </p> https://legacy.forums.gravityhelp.com/topic/populate-hidden-field-with-php-multiple-times#post-23859 Thu, 21 Apr 2011 11:44:15 +0000 Bryan K 23859@https://legacy.forums.gravityhelp.com/ <p>Oh dear. Yup, that's all it took. Thanks! I really should have tried that. :)</p> <p>One other question as long as I'm asking: Is there a way to enable AJAX on the gravity_form(2, true, true); thing? I've tried looking around and haven't been able to find that either. </p> https://legacy.forums.gravityhelp.com/topic/populate-hidden-field-with-php-multiple-times#post-23846 Thu, 21 Apr 2011 11:08:43 +0000 Carl Hancock 23846@https://legacy.forums.gravityhelp.com/ <p>Try putting that filter in your themes functions.php file and not in your loop. </p> https://legacy.forums.gravityhelp.com/topic/populate-hidden-field-with-php-multiple-times#post-23817 Thu, 21 Apr 2011 01:37:29 +0000 Bryan K 23817@https://legacy.forums.gravityhelp.com/ <p>Hello,</p> <p>I have a form inside of the loop in a template so it shows up multiple times on a page, so I need to somehow distinguish which form was submitted in the entry information. After poking around on the forum I've come up with this. Sorry it's probably terrible – I'm not super great at PHP:</p> <pre><code>&lt;?php add_filter(&quot;gform_field_value_book&quot;, &quot;populate_book&quot;); function populate_book($value){ return get_the_title(); } gravity_form(2, true, true); ?&gt;</code></pre> <p>Which prepopulates a hidden field called book with the title of the post the form is part of. It works like a charm until the second post on the page, where there's a fatal PHP error that the populate_book function has already been defined.</p> <p>There must be a way to do this, right? Am I going at it the wrong way?</p> <p>Thanks so much for any help. </p>
