How to Add an Onclick Attribute to Your WPForms Submit Button
As a WordPress website owner, you're likely familiar with the powerful form-building plugin, WPForms. With its intuitive drag-and-drop interface and robust feature set, WPForms has become a go-to choice for creating custom forms on your site. However, sometimes you may need to go beyond the plugin's out-of-the-box functionality to achieve specific customizations, such as adding an Onclick attribute to your form's submit button.
In this article, we'll explore a step-by-step guide on how to add an Onclick attribute to your WPForms submit button, without having to modify the plugin's core files. By the end of this post, you'll be able to track conversions, implement custom JavaScript functionality, and enhance the overall user experience of your website's forms.
Understanding the Challenge
The WPForms plugin is designed to be user-friendly and easy to use, which is one of the reasons it has become so popular among WordPress users. However, this simplicity can sometimes limit the ability to make more advanced customizations to the form's behavior and appearance.
One common request from WPForms users is the ability to add an Onclick attribute to the form's submit button. This attribute is often used to trigger custom JavaScript functions, such as conversion tracking or additional form validation. Unfortunately, the WPForms documentation doesn't explicitly mention a way to add this attribute through their provided hook filters.
The Solution: Using jQuery and Hook Filters
While the WPForms documentation may not explicitly mention a way to add an Onclick attribute to the submit button, there are a few workarounds that you can use to achieve this functionality. In this article, we'll focus on two methods: using jQuery and utilizing WPForms' hook filters.
Method 1: Using jQuery
One of the easiest ways to add an Onclick attribute to your WPForms submit button is by using jQuery. jQuery is a popular JavaScript library that simplifies many common JavaScript tasks, including DOM manipulation and event handling.
Here's an example of how you can use jQuery to add an Onclick attribute to your WPForms submit button:
jQuery('#wpforms-submit-2113').click(function(){
gtag_report_conversion('http://example.com/your-link');
});
In this code snippet, we're selecting the submit button with the ID wpforms-submit-2113
and attaching a click event handler to it. Inside the event handler, we're calling the gtag_report_conversion()
function, which is a custom function that might be used for conversion tracking (e.g., Google Analytics or Google Tag Manager).
If you want to apply this to all WPForms submit buttons on your site, you can use the more general selector .wpforms-submit
:
jQuery('.wpforms-submit').click(function(){
gtag_report_conversion('http://example.com/your-link');
});
This will attach the click event handler to all WPForms submit buttons on your site, regardless of their individual IDs.
To use this method, you'll need to include the jQuery library on your WordPress site and then place the JavaScript code in a custom plugin or in the functions.php
file of your WordPress theme.
Method 2: Utilizing WPForms' Hook Filters
Another approach to adding an Onclick attribute to your WPForms submit button is by using the plugin's hook filters. WPForms provides a set of filters that allow you to modify the output of various form elements, including the submit button.
Here's an example of how you can use the wpforms_html_field_button
filter to add an Onclick attribute to the submit button:
add_filter('wpforms_html_field_button', 'add_onclick_to_submit_button', 10, 2);
function add_onclick_to_submit_button($button, $field) {
if ($field['type'] === 'submit') {
$button = str_replace('<button', '<button onclick="gtag_report_conversion(\'http://example.com/your-link\')"', $button);
}
return $button;
}
In this code, we're using the wpforms_html_field_button
filter to modify the HTML output of the submit button. We first check if the field type is submit
, and if so, we replace the <button>
tag with a modified version that includes the Onclick attribute.
Similar to the jQuery method, the Onclick attribute in this example calls the gtag_report_conversion()
function, which could be used for conversion tracking.
To use this method, you'll need to place the code in a custom plugin or in the functions.php
file of your WordPress theme.
Comparing the Two Methods
Both the jQuery and hook filter methods can be effective in adding an Onclick attribute to your WPForms submit button. However, there are some key differences between the two approaches:
-
Flexibility: The jQuery method is more flexible, as it allows you to add any custom JavaScript functionality to the submit button's click event. The hook filter method is more limited to modifying the HTML output of the button.
-
Scope: The jQuery method can be applied to specific form IDs or all WPForms submit buttons on your site. The hook filter method applies the Onclick attribute to all WPForms submit buttons.
-
Dependency: The jQuery method requires the inclusion of the jQuery library on your site, while the hook filter method doesn't have any external dependencies.
-
Maintainability: The hook filter method is more maintainable, as it doesn't require you to manage any JavaScript code in your theme or plugin. The jQuery method may require more attention if you need to update or modify the custom JavaScript functionality.
Ultimately, the choice between the two methods will depend on your specific requirements and preferences. If you need more flexibility and control over the submit button's behavior, the jQuery method might be the better choice. If you prefer a more straightforward and maintainable solution, the hook filter method could be a better fit.
