You would dynamically populate a list field using the gform_field_value_$parameter_name filter which is documented here:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Gform_field_value_$parameter_name" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_value_$parameter_name</a></p> <p>You would first need to set the field so that it can be populated dynamically and give it a parameter name. You do this by editing the form and then editing your list field. The dynamic population option is under the Advanced tab.</p> <p>The following is a sample snippet that will help you with the data format. This example assumes you used "list" as the parameter name for that field and that it is a multi-column list field. You can customize it to suit your needs (single column, more columns, less columns, etc.).</p> <pre><code>add_filter(&quot;gform_field_value_list&quot;, &quot;populate_list&quot;); function populate_list($value){ return array(&quot;row 1 - col1&quot;,&quot;row 1 - col2&quot;, &quot;row 1 - col3&quot;, &quot;row 2 - col1&quot;, &quot;row 2 - col2&quot;, &quot;row 2 - col3&quot;, &quot;row 3 - col1&quot;, &quot;row 3 - col2&quot;, &quot;row 3 - col3&quot;); }</code></pre> <p>There is also a How To page on how to dynamically populate fields using the same filter, although it doesn't use a List Field as an example. You can find that How To here:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Using_Dynamic_Population" rel="nofollow">http://www.gravityhelp.com/documentation/page/Using_Dynamic_Population</a> </p> https://legacy.forums.gravityhelp.com/topic/dynamically-populate-list-field-example-needed#post-49303 Mon, 13 Feb 2012 16:52:14 +0000 carcinomad 49303@https://legacy.forums.gravityhelp.com/ <p>I just need a simple example how to dynamically populate the list field during a pre_render. </p>
