推荐答案

在下面显示的示例代码中，我们首先检查表单ID，以确保其与目标表单匹配.然后，我们要检查特定字段(通过字段ID)以查看其是否为空.

In the example code you’ll see below, we’re first checking the form ID to make sure it matches the form that’s being targeted. Then we’re checking a specific field (by the field ID) to see if it’s empty.

只需记住将表单ID从5更改为与您的表单ID相匹配，并更改为"4"以与您的字段ID相匹配.

Just remember to change the form ID from 5 to match your form ID and change the '4' to match your field ID.

function wpf_dev_process( $fields, $entry, $form_data ) {

    // Optional, you can limit to specific forms. Below, we restrict output to
    // form #5.
    if ( absint( $form_data['id'] ) !== 5 ) {
        return $fields;
    }

    // check the field ID 4 to see if it's empty and if it is, run the error    
    if(empty($fields[4]['value'])) 
        {
            // Add to global errors. This will stop form entry from being saved to the database.
            // Uncomment the line below if you need to display the error above the form.
            // wpforms()->process->errors[ $form_data['id'] ]['header'] = esc_html__( 'Some error occurred.', 'plugin-domain' );    

            // Check the field ID 4 and show error message at the top of form and under the specific field
               wpforms()->process->errors[ $form_data['id'] ] [ '4' ] = esc_html__( 'Some error occurred.', 'plugin-domain' );

            // Add additional logic (what to do if error is not displayed)
        }
    }
add_action( 'wpforms_process', 'wpf_dev_process', 10, 3 );
