How to Handle the Contact Form 7 Call Submit Event in jQuery: Preventing Empty Submissions
As a WordPress developer, you may often find yourself working with the popular Contact Form 7 plugin to create and manage forms on your website. One common challenge you might encounter is handling the form submission process, particularly when it comes to ensuring that required fields are filled out before the form is submitted.
In this article, we'll explore a solution using jQuery to handle the Contact Form 7 call submit event, focusing on preventing the form from being submitted if certain fields are left empty. We'll also discuss how to handle form submissions made by pressing the Enter key.
Understanding the Contact Form 7 Call Submit Event
The Contact Form 7 plugin provides a set of events that you can use to interact with the form submission process. One of these events is the wpcf7submit
event, which is triggered when a form is submitted.
You can use jQuery to listen for this event and perform additional actions, such as validating the form fields before allowing the submission to proceed.
Here's an example of how you can set up an event listener for the wpcf7submit
event:
$('.wpcf7-submit').on('click', function(e) {
var testInput = $('input[name="test"]').val();
if (testInput === '') {
e.preventDefault();
}
});
In this example, we're listening for the click
event on the .wpcf7-submit
element, which is the submit button for the Contact Form 7 form. Inside the event handler, we're checking the value of the test
input field. If the field is empty, we're calling the preventDefault()
method to stop the form from being submitted.
Handling Form Submissions with the Enter Key
While the above approach works for form submissions made by clicking the submit button, it doesn't address a common scenario: users submitting the form by pressing the Enter key.
To handle this case, we need to listen for the submit
event on the form itself, rather than the click
event on the submit button. This ensures that all form submission methods are covered, including pressing the Enter key.
Here's an updated version of the code that handles both click and Enter key submissions:
$('#myForm').on('submit', function(e) {
var testInput = $('input[name="test"]').val();
if (testInput === '') {
e.preventDefault();
}
});
In this example, we're using the #myForm
selector to target the form itself, and we're listening for the submit
event. The rest of the logic remains the same: we're checking the value of the test
input field and, if it's empty, we're calling preventDefault()
to stop the form from being submitted.
Providing Feedback to Users
While preventing empty form submissions is an important step, it's also important to provide feedback to the user about why the form wasn't submitted. This helps improve the user experience and ensures that the user knows what they need to do to successfully submit the form.
One way to provide feedback is to display a custom error message or validation message near the input field that was left empty. You can use jQuery to target the specific input field and add the error message.
Here's an example of how you can do this:
$('#myForm').on('submit', function(e) {
var testInput = $('input[name="test"]').val();
if (testInput === '') {
e.preventDefault();
$('input[name="test"]').after('<div class="error-message">Please fill out this field.</div>');
}
});
In this example, we're adding a <div>
element with the class error-message
right after the test
input field. You can style this error message using CSS to make it visually appealing and clear to the user.
Handling Multiple Required Fields
In a real-world scenario, you're likely to have multiple required fields in your Contact Form 7 form. To handle this, you can expand the code to check each required field and add an error message for each one that is left empty.
Here's an example:
$('#myForm').on('submit', function(e) {
var nameInput = $('input[name="name"]').val();
var emailInput = $('input[name="email"]').val();
var messageInput = $('textarea[name="message"]').val();
var hasEmptyFields = false;
if (nameInput === '') {
$('input[name="name"]').after('<div class="error-message">Please enter your name.</div>');
hasEmptyFields = true;
}
if (emailInput === '') {
$('input[name="email"]').after('<div class="error-message">Please enter your email address.</div>');
hasEmptyFields = true;
}
if (messageInput === '') {
$('textarea[name="message"]').after('<div class="error-message">Please enter your message.</div>');
hasEmptyFields = true;
}
if (hasEmptyFields) {
e.preventDefault();
}
});
In this example, we're checking the values of the name
, email
, and message
fields. If any of them are empty, we're adding an error message next to the corresponding input field and setting a flag hasEmptyFields
to true
. Finally, if hasEmptyFields
is true
, we're calling preventDefault()
to stop the form from being submitted.
