Using Gravity Forms ‘gform_column_input_content’ PHP filter

The gform_column_input_content Gravity Forms PHP filter can be used to modify the HTML content of the list field column input tag.


add_filter('gform_column_input_content', 'your_function_name', 10, 6);

You can also target a specific column by adding the form id, field id, and column number after the hook name (format: gform_column_input_content_FORMID_FIELDID_COLUMN).

// This filter declaration targets the third column of the field whose id is 9 in the form whose id is 21
add_filter('gform_column_input_content_21_9_3', 'your_function_name', 10, 6);


  • $input (string): The current HTML content of the List field column.
  • $input_info (array): The input info array to be filtered, in the following format:
    'type' => 'select',
    'choices' => 'First Choice,Second Choice'

// OR, if values need to be specified for each choice, the following format can also be used:
    'type' => 'select',
    'choices' => array(
        array('text' => 'First Choice', 'value' => 'First'),
        array('text' => 'Second Choice', 'value' => 'Second')
  • $field (Field Object): Current field.
  • $text (string): Current column name.
  • $value (string): Currently entered/selected value for the column’s input.
  • $form_id (integer): ID of the current form.

Change the third column to a textarea

This example changes the third column of the list field to a textarea. To display the value on the entry in the admin, make sure you include using $value in the appropriate location for your tag creation.

add_filter('gform_column_input_content_21_9_3', 'change_column3_content', 10, 6);

function change_column3_content($input, $input_info, $field, $text, $value, $form_id) {
    // build field name, must match List field syntax to be processed correctly
    $input_field_name = 'input_' . $field->id . '[]';
    $new_input = '<textarea name="' . $input_field_name . '" class="textarea medium" cols="50" rows="10">' . $value . '</textarea>';
    return $new_input;


This code can be placed in the functions.php file of the active theme, a custom functions plugin, or a custom add-on.
