Hi,
I need to connect a select field to another field in order to fetch data. I have already written the codes but which of the .php files would I edit and what part of the file will I insert the codes?

Regards,
Sanya

Here is the code:

if ($row->id == 15) {
$query = "SELECT element_value FROM " . $wpdb->prefix . "formmaker_submits WHERE form_id=13 AND element_label=1";
$category_names = $wpdb->get_col($query);
$category_options = '';
foreach ($category_names as $key => $category_name) {
if ($category_name != '') {
$category_options .= '<option onselect="set_select(\'1_option0' . ($key + 1) . '\')" value="' . $category_name . '" id="1_option0' . ($key + 1) . '">' . $category_name . '</option>';
}
}
// var_dump(esc_html($row->form_front));
// $row->form_front = preg_replace('/<select id="1_element15"(.*?)<\/select>/', 'b<select id="1_element15" name="1_element15" style="width: 200px;" onchange="set_select(this)"><option id="1_option0" value="" onselect="set_select(\'1_option0\')" selected="selected">Select value</option>' . $category_options . '</select>', $row->form_front);
$row->form_front = str_replace('<select onchange="set_select(this)" style="width: 200px;" name="1_elementform_id_temp" id="1_elementform_id_temp">', '<select onchange="set_select(this)" style="width: 200px;" name="1_elementform_id_temp" id="1_elementform_id_temp">' . $category_options, $row->form_front);
}
