Make sure the field has a check in allow to populate dynamically. And look at the documentation for pre_rendering a form as an example of the function you will want to create using the post_paging hook. <a href="http://www.gravityhelp.com/documentation/page/Gform_pre_render" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_pre_render</a> Ketiga on "Dynamic population - parameter outputs outside the form, but not in form fields" https://legacy.forums.gravityhelp.com/topic/dynamic-population-parameter-outputs-outside-the-form-but-not-in-form-fields#post-64747 Wed, 04 Jul 2012 11:31:09 +0000 Ketiga 64747@https://legacy.forums.gravityhelp.com/ Thank you for the explanation. What I don't understand is that simple html input fields show the result just fine. Isn't there a different gravity forms type of field or function that can be used for this? Also, the second field is on page two of my form so I expected it to load select_stuff again and then use the value of input_13 that was typed in. But I understand this is not the way it works either then?

So that the database can run its query and return a result from what a user typed in. Or you need some JavaScript (not my specialty) to do this using JQuery or something..

So what is currently happening is that it is checking input_13 on load of select_stuff and that is before a user has a chance to put anything in. If input_13 had a default value of "Start" then select_stuff should have a value of Start. But when a user changes the text, it won't update what is in the select_stuff field because there is no JavaScript making this happen live.

The value entered in that field is used to compare with database values. There is a result when there's a match and this result should be returned in a separate field. The code works used as regular php. But in gravity forms "No Match" is what always shows in the result field, because somehow it looks like it loses the variable entered in 'input_13' David Peralty on "Dynamic population - parameter outputs outside the form, but not in form fields" https://legacy.forums.gravityhelp.com/topic/dynamic-population-parameter-outputs-outside-the-form-but-not-in-form-fields#post-64739 Wed, 04 Jul 2012 10:55:35 +0000 David Peralty 64739@https://legacy.forums.gravityhelp.com/ Your function should be: <pre><code>function select_stuff($value){</code></pre> Also, where are you getting input_13? A previous form?

In: <code>WHERE wp_usermeta.meta_key='$my_value'</code> $my_value what's entered in a gravity forms field value so I guess it could be this as well: <code>WHERE wp_usermeta.meta_key=$_POST["input_13"]</code> I then use the parameter name 'select_stuff' to try and dynamically populate my form field with the result of the function. But in Gravity Forms it won't output the result in a field. When I execute the function anywhere else in the page (outside gravity forms) or use a custom html form input field, it does show the result just fine. I just tested again with this simple code in my functions.php file. <pre><code>add_filter('gform_field_value_select_stuff', 'select_stuff'); function select_stuff(){ return $_POST["input_13"]; }</code></pre> Works anywhere on my page except when I use parameter name 'select_stuff' in a Gravity forms field. The result of this part "No Match": <pre><code>if(mysql_num_rows($result)==0){ return "No Match"; }</code></pre> DOES show in my gravity form field with the parameter set, even though the previous condition is met... Hope it's somewhat clear..:)
