I took a look at GF and found this filter somewhat useful: gform_field_choices_# (where # is the form ID).</p> <p>This is the sample code I came up with for him (without the specifics for my form):<br /> <pre><code>function testing_gform_field_choices( $choices, $field ) { if ( 1 == $field[&#39;id&#39;] ) { // 1 = the Field ID of the field you&#39;re wanting to modify. unset( $field[&#39;choices&#39;] ); $field[&#39;choices&#39;][] = array( &#39;text&#39; =&gt; &#39;Testing 1&#39;, &#39;value&#39; =&gt; &#39;Testing 1&#39;, &#39;isSelected&#39; =&gt; false, &#39;price&#39; =&gt; false ); $field[&#39;choices&#39;][] = array( &#39;text&#39; =&gt; &#39;Testing 2&#39;, &#39;value&#39; =&gt; &#39;Testing 2&#39;, &#39;isSelected&#39; =&gt; false, &#39;price&#39; =&gt; false ); $field[&#39;formId&#39;] = &#39;DO_NOT_RUN&#39;; // We don&#39;t want to get into an endless add_filter loop, so change the ID to someting useless. $choices = GFCommon::get_radio_choices( $field, &#39;&#39;, &#39;&#39; ); // Rerun the GF script to make it look pretty again } return $choices; } add_filter( &#39;gform_field_choices_1&#39;, &#39;testing_gform_field_choices&#39;, 10, 2 ); // _1 = the FORM ID of the form you want to modify</code></pre> <p>So, I unset choices, add my "dynamic" choices, change the 'formID' to some junk value (so the filter doesn't run in an endless loop), get my new $choices variable and return it.</p> <p>It would be great if there was a "pre_gfrom_field_choices" filter at the head of the get_radio_choices and get_checkbox_choices functions. One that simply let us modify the $field['choices'] array. Doing it this way doubles the work... not a huge deal, but would be a good addition tot he code.</p> <p>Anyway, if that doesn't come to fruition, I hope the above code helps someone who wants to do something similar.</p> <p>Lew Ayotte </p>
