If you mean access each checkbox choice inside a field, you don't need to do it. Just return the choice text as one of the items in the comma separated list and that specific checkbox will be checked. If you are asking how to access each checkbox field, you do that by the parameter name. When you turn on the option in the form settings to "Allow field to be populated dynamically", you give it a parameter name. That name is used in the hook. <pre><code>add_filter("gform_field_value_$parameter_name", "populate_checkbox");</code></pre> In your example above, the parameter name was "checkbox", so we used "gform_field_value_checkbox" for the filter name: <pre><code>add_filter("gform_field_value_checkbox", "populate_checkbox");</code></pre> adomedia on "checking or unchecking checkbox on form render" https://legacy.forums.gravityhelp.com/topic/checking-or-unchecking-checkbox-on-form-render#post-29739 Mon, 11 Jul 2011 18:24:45 +0000 adomedia 29739@https://legacy.forums.gravityhelp.com/ Ok, that's makes sense. How do I reference each of the checkboxes? By id? Or by the order in which they are generated?

If you want a choice to remain unchecked, simply don't include it in the list. In my example below, the items "First" and "Second" will be checked, while all other choices I have in that field will remain unchecked. <pre><code>function populate_checkbox(){ return "First,Second"; } add_filter("gform_field_value_checkbox", "populate_checkbox");</code></pre> adomedia on "checking or unchecking checkbox on form render" https://legacy.forums.gravityhelp.com/topic/checking-or-unchecking-checkbox-on-form-render#post-29632 Mon, 11 Jul 2011 12:26:56 +0000 adomedia 29632@https://legacy.forums.gravityhelp.com/ ??? any ideas ??? adomedia on "checking or unchecking checkbox on form render" https://legacy.forums.gravityhelp.com/topic/checking-or-unchecking-checkbox-on-form-render#post-29601 Mon, 11 Jul 2011 08:47:11 +0000 adomedia 29601@https://legacy.forums.gravityhelp.com/ Ho would I pre populate a checkbox with "checked" or "unchecked" depending on a variable I pass to the function? so far I have: <pre><code>function populate_checkbox() { if(meets criteria) { check the box (what goes here???) } else { don't check the box } add_filter("gform_field_value_checkbox", "populate_checkbox");</code></pre>
