What and Why?

This is an extension to add additional fields for Tickets and RSVPs. Event Tickets and Event Tickets Plus are required.

How?

You can add the following code to another plugin or in your theme functions.php file:

<?php

add_filter( 'tribe_ext_tickets_additional_fields', 'custom_tickets_additional_fields' );

function custom_tickets_additional_fields( $ticket_fields ) {

		$ticket_fields['teacher_name'] = [
			'type'        => 'text',
			'label'       => esc_html__( 'Teacher name' ),
			'description' => esc_html__( 'Insert the name of the teacher or person hosting.' ),
		];

		$ticket_fields['teacher_email'] = [
			'type'        => 'email',
			'label'       => esc_html__( 'Teacher email' ),
			'description' => esc_html__( 'Insert the email of the teacher or person hosting.' ),
		];
		
		$ticket_fields['teacher_id'] = [
			'type'        => 'number',
			'label'       => esc_html__( 'Teacher ID' ),
			'description' => esc_html__( 'Insert the Teacher ID number.' ),
		];

		$ticket_fields['is_mandatory'] = [
			'type'        => 'checkbox',
			'label'       => esc_html__( 'Is mandatory' ),
			'description' => esc_html__( 'Check box if attendance is mandatory' ),
		];

		$ticket_fields['zoom_link'] = [
			'type'        => 'url',
			'label'       => esc_html__( 'Zoom link' ),
			'description' => esc_html__( 'Insert the zoom link to share a link of the meeting.' ),
		];

		$ticket_fields['youtube_embed'] = [
			'type'        => 'textarea',
			'label'       => esc_html__( 'Youtube Embed' ),
			'description' => esc_html__( 'Insert the youtube embed of the video they have access to when they purchase the ticket.' ),
		];

		return $ticket_fields;
}

This way the additional fields will be added on the ticket box or the RSVP box under the "Additional Fields" section.

On a code basis, there's a template tag called tribe_ext_tickets_additional_fields_get_meta() that will allow you to get the value wherever you need it, like this:

// Replace `123` with your ticket ID.
tribe_ext_tickets_additional_fields_get_meta( 123, 'zoom_link' );

Printing the fields

You can either use a template tag, or you can also use the the [tribe_tickets_additional_field] shortcode if you also have the Event Tickets Shortcodes Extension.

Using the template tag

You can use the function tribe_ext_tickets_additional_fields_get_meta() in your code, like this:

// Replace `123` with your ticket ID.
tribe_ext_tickets_additional_fields_get_meta( 123, 'zoom_link' );

Using the Shortcode

As mentioned above. For this to work you'll need Event Tickets Plus installed and active on your site.

The shortcode has two required parameters, the ticket_id and the field. The ticket_id parameter is the ID of the ticket (post or page. The field parameter is the ID you use when defining the field. In the previous example: zoom_link, teacher_name, teacher_email and youtube_embed.

Example usage:

[tribe_tickets_additional_field ticket_id="123" field="zoom_link"]

Where 123 is the ID of the ticket

Finally, if by any chance you want to modify the output of the shortcode you can hook into the tribe_tickets_additional_field_shortcode_html filter, which parameters are the $html, $ticket_id and $field.

add_filter( 'tribe_tickets_additional_field_shortcode_html', 'my_custom_additional_field_shortcode_printing', 10, 3 );

function my_custom_additional_field_shortcode_printing( $html, $ticket_id, $field ) {

	if ( 'zoom_link' === $field ) {
		$html = 'I do not want to print any zoom link!';
	}

	if ( 123 === $ticket_id ) {
		$html = 'I do not want to print any field for the ticket 123';
	}

	return $html;
}
