Save the values of checkboxes from a Formidable Form

formidable-forms-checkbox-values.php

//You can use this to load the values from checkboxes in a Formidable form.
//In Formidable Forms for WordPress, when you want to retrieve the values of checkboxes using the frm_after_create_entry hook, 
//you need to access the form entry data that's passed to your hook function. 
//This hook is triggered after an entry is created, and it provides you with all the submitted data.
add_action('frm_after_create_entry', 'get_checkbox_values', 30, 2);
function get_checkbox_values($entry_id, $form_id){
    // Check if it's the specific form you want (replace 123 with your form ID)
    if ($form_id == 123) {
        // Get the entry object
        $entry = FrmEntry::getOne($entry_id, true);

        // Replace 'your_field_key' with the key of your checkbox field
        $checkbox_values = $entry->metas['your_field_key'];

        // Do something with the checkbox values
        // $checkbox_values is an array if multiple boxes can be checked
        foreach ($checkbox_values as $value) {
            // Handle each value
        }
    }
}

//You can populate the values from an array
//To pre-populate checkboxes in Formidable Forms using the frm_get_default_value hook, 
//this assumes an array of values that you want to set as the default for the checkbox field. 
//This hook allows you to set a default value for a field when the form is first loaded which can also be used to load
//values from a database or other source.

        // Define the default values as an array
        // These should match the values assigned to the checkboxes
        $default_values = array('Value1', 'Value3');

        // Set the default values for the checkboxes
