Using the Hook #

Developers can modify form fields using this hook by adding their custom function through add_filter. Below are common use cases:

1. Adding a New Field #

To add a new field, such as a date of birth field:

add_filter( 'formychat_form_fields', function( $fields ) {
    $fields[] = [
        'name' => 'dob',
        'type' => 'date',
        'default' => '',
        'help_text' => 'Enter your Date of Birth',
        'attributes' => [
            'placeholder' => __( 'Select your Date of Birth', 'social-contact-form' ),
            'required' => false,
],
    ];
    return $fields;
} );

2. Removing an Existing Field #

If a field like phone is unnecessary, it can be removed:

add_filter( 'formychat_form_fields', function( $fields ) {

    return array_filter( $fields, function( $field ) {

        return $field['name'] !== 'phone';

    } );

} );

3. Modifying an Existing Field #

To make the email field optional instead of required:

add_filter( 'formychat_form_fields', function( $fields ) {

    foreach ( $fields as &$field ) {

        if ( $field['name'] === 'email' ) {

            $field['attributes']['required'] = false;

        }

    }

    return $fields;

} );

Best Practices #

• Always validate user input when adding new fields to ensure data security.
• Use meaningful placeholders and help texts to improve user experience.
• Set appropriate attributes (e.g., required, maxlength) to enforce data integrity.
• Test modifications thoroughly to prevent errors or unexpected behaviors in the form.

Conclusion #

The formychat_form_fields hook is a powerful tool for customizing form fields dynamically in FormyChat. By leveraging this hook, developers can enhance user interactions, collect relevant information, and optimize form usability.
