Where to put the code
Any time you add a custom PHP function to your site, insert it in the WPCode plugin for code snippets (recommended), a child theme's functions.php, or your custom plugin.
If you insert PHP code using the WPCode plugin, ensure that the PHP Snippet is selected as the code type.
If you're unfamiliar with using WordPress filters, you can find more details in the WordPress docs.
Duplicating a function
If you are attempting to use the same function or hook multiple times, you can't just duplicate the code and change field ids. Using the same function name twice will result in fatal errors on your site. To avoid this issue, you must change the function name any time you use the same code more than once on your site.
The function name is typically in two places within the code and needs to be changed in both places it occurs. In this example, the function name "check_entry_count" would need to be changed to something unique like "check_entry_count2" or "check_formb_entry_count". As long as the function names are unique, you can use the same custom code multiple times.
add_action('frm_display_form_action', 'check_entry_count', 8, 3);
function check_entry_count($params, $fields, $form){
global $user_ID;
remove_filter('frm_continue_to_new', '__return_false', 50);
if($form->id == 11 and !is_admin()){ //replace 5 with the ID of your form
$count = FrmEntry::getRecordCount("form_id=". $form->id ." AND user_id=".$user_ID);
if($count >= 1){ //change 2 to your entry limit
echo 'This form is closed';
add_filter('frm_continue_to_new', '__return_false', 50);
}
}
}

frm_jquery_ui_base_url: Some jQuery scripts and styles are loaded from the external Google API (ajax.googleapis.com/ajax/libs/jqueryui/####). This hook allows this URL to be changed. Files loaded from this URL includes:

- When unfiltered HTML is disallowed, it means that we will run kses on it. Script tags will not work, as well as other unexpected HTML that could be possibly unsafe but plenty of HTML will continue to work even when HTML is being filtered.

You would need to run add_action( 'plugins_loaded', 'FrmAppHelper::save_combined_js' ); once to regenerate the JS (but you do not want to run that on every page load, just the first filter).
frm_include_maskedinput_in_minified_js: Use this filter to exclude jQuery Masked Input from frm.min.js.
