If you are using Advanced Custom Fields (ACF) plugin in WordPress and facing issues with your frontend form not submitting, there are a few possible reasons for this. One common reason is that the form is missing the necessary attributes and action URL to submit the data.
To resolve this issue, you can use the following code snippet as an example to create a frontend form using ACF and ensure it submits successfully:
<?php
// Create a function to handle form submission
function wpsnippets_handle_form_submission() {
// Check if the form is submitted
if (isset($_POST['submit'])) {
// Retrieve the form data
$field_value = $_POST['field_name'];
// Perform any necessary validation or processing here
// Save the form data to the database using ACF's update_field() function
update_field('field_name', $field_value, 'option');
}
}
add_action('init', 'wpsnippets_handle_form_submission');
?>
<!-- Create the frontend form -->
<form method="post" action="">
<!-- Add your ACF fields here -->
<input type="text" name="field_name" value="" />
<!-- Add a submit button -->
<input type="submit" name="submit" value="Submit" />
</form>
In this code snippet, we first define a function wpsnippets_handle_form_submission() that handles the form submission. Inside this function, we check if the form is submitted using the isset() function. If the form is submitted, we retrieve the value of the form field using $_POST['field_name']. You can replace 'field_name' with the actual name of your ACF field.
After retrieving the form data, you can perform any necessary validation or processing. Then, we use ACF’s update_field() function to save the form data to the database. In this example, we are saving the data to the options table by passing 'option' as the third parameter.
Next, we use the add_action() function to hook our form submission function to the 'init' action. This ensures that the function is executed when WordPress initializes.
Finally, we create the frontend form using HTML <form> element. Inside the form, you can add your ACF fields as needed. Make sure to set the name attribute of each field to match the field name you used in the PHP code.
Remember to replace 'field_name' with the actual name of your ACF field in both the PHP code and the HTML form.
By using this code snippet, you should be able to create a frontend form with ACF fields that submits successfully.
