Testimonials - Submissions

Front end posting of 'Testimonials by WooThemes' plugin. Form and processing via CMB2 (CMB2 is built in to this plugin). This plugin doesn't load stylesheet for your form. It's purposely lightweight. Add your own styles inside your theme or a custom plugin. Some basic CSS examples are below.

I'm still a bit new to GitHub, but pull requests are welcomed if you'd like to contribute code.

TODO: Add support for 'testimonial-category' custom taxonomy

This is a 3rd party plugin, no affiliation with WooThemes.

Shortcode

[tbws_form]

[tbws_form post_status="%your status here%"]

Use shortcode [tbws_form] to insert the submission form on any WP post/page. Submissions default to a post status of draft so they can be manually approved. If you want your submissions to be published immediately you can use the post_status attribute in the shortcode. Example [tbws_form post_status="publish"].

Hooks & Filters

There are a number of hooks and filters included in the plugin for quickly customizing the form

* Form output

tbws_submission_form

This filter runs at prior to outputting the form via the shortcode. You can use it to display content, or restrict access to the form for various conditions.

Example usage:

// Restric access to testimonial submission for if not logged in
add_filter( 'tbws_submission_form', 'prefix_form_require_logged_in_user' );
function prefix_form_require_logged_in_user( $output ) {
    // Show a login form if not logged in
    if ( ! is_user_logged_in() ) {
        $output = '<p>' . __( 'You must be a logged in to submit a testimonial.', 'text-domain' ) . '</p>';
        $output .= wp_login_form( array( 'echo' => false ) );
        return $output;
    }
    // Otherwise, show the default output
    return $output;
}

* Form fields

These hook allows you to add more fields to the form. Accepts anything CMB2 allows, including any custom field types you create

tbws_form_before

tbws_form_content_field_before

tbws_form_after

Example usage:

// Add a new text field after the form
// This field can be added to post_meta via tbws_submitted_post_meta filter
add_action( 'tbws_form_after', 'prefix_my_new_form_field' );
function prefix_my_new_form_field( $cmb ) {
    $cmb->add_field( array(
        'name'    => __( 'New Field Title', 'tbws' ),
        'desc'    => __( 'New field description (optional)', 'tbws' ),
        'id'      => 'submitted_post_before', // ID can be whatever you want, use this for processing later
        'type'    => 'text_url',
    ) );
}

* Form data processing

These filters allow you to process the data submitted by the form, including any custom form fields you may have added

tbws_submitted_post_data - Filter the post data prior to wp_insert_post

tbws_submitted_post_meta - Filter the post meta prior to update_post_meta

tbws_content_kses - Change wp_kses arguments See https://codex.wordpress.org/Function_Reference/wp_kses

Example usage:

// Process our new form field data to a custom field key
add_filter( 'tbws_submitted_post_meta', 'prefix_process_my_field_data' );
function prefix_process_my_field_data( $post_meta ) {
    if ( ! empty( $_POST['submitted_post_before'] ) ) {
        $post_meta['my_custom_meta_key'] = $sanitized_values['submitted_post_before'];
    }
    return $post_meta;
}

* Form redirect

Filter the redirect url

tbws_success_redirect

* Form success message

Filter the success message HTML

tbws_success_message
