YouTube Videos display for Zen Cart [Support Thread]

[richard7315]

Hi,
I have just submitted a new module to allow YouTube video display on products. It is now available on Github.

## Overview

This module adds YouTube video functionality to Zen Cart product pages. Store owners can easily add a YouTube video ID to any product in the admin panel, and the video will be displayed on the product's detail page in the storefront.

## Features

- **Easy Admin Interface**: Add YouTube video IDs directly in the product edit form
- **Responsive Video Display**: Videos are displayed in a responsive iframe that adapts to different screen sizes
- **Privacy-Focused**: Uses `youtube-nocookie.com` domain to minimize tracking

## Requirements

- Zen Cart v2.0.0 or higher (tested with v2.1.0)
- PHP 7.4 or higher

Moderators – please use the second version I submitted (v1.0.1) with the updated readme file.

Zen Cart Iframes In Product Descriptions

The reason I developed this module was due to the limitations with CKEditor 5 – any existing iframes are removed when saving product descriptions. Essentially, iframes are no longer supported in Zen Cart 2.1.0 product descriptions.

This module allows YouTube video iframes to be embedded on product pages – hopefully this will be helpful to some users.

Following some very helpful feedback on GitHub I have updated the module to version 1.0.3. The following changes have been made:

1) Module has been refactored to eliminate the need for a modified main_template_vars.php
2) The module now only requires one modified core file (tpl_product_info_display.php for the HTML) instead of two, significantly reducing upgrade conflicts and maintenance burden.
3) Removed the need for the admin auto-loading config file

Nice one!

May I just suggest one tiny improvement? Don't force admins to "extract" the video ID - it's a waste of time and leaves room for error (by accidentally deleting a character). Allowing a copy/paste from the address bar or using the Share button on YT makes it easier and much faster for the admin... Here's a function I use on multiple sites (tested):

function extractYouTubeID($url) {
    // If it's already an ID (no "http" in it), return as is
    if (preg_match('/^[a-zA-Z0-9_-]{11}$/', $url)) {
        return $url;
    }

    // Parse the URL
    $parsedUrl = parse_url($url);

    // Check for short YouTube URL
    if (isset($parsedUrl['host']) && $parsedUrl['host'] === 'youtu.be' && isset($parsedUrl['path'])) {
        return ltrim($parsedUrl['path'], '/');
    }

    if (!isset($parsedUrl['query'])) {
        return false; // Invalid format
    }

    // Parse query parameters
    parse_str($parsedUrl['query'], $queryParams);

    // Return the video ID if it exists
    return $queryParams['v'] ?? false;
}

You can place it in your observer file and simply call it instead of

$youtube_video_id = preg_replace('/[^a-zA-Z0-9_-]/', '', $youtube_video_id);

Many thanks for your suggestion. Your right, that would be much easier for end users.

I've updated the module to v1.0.4 incorporating your extractYouTubeID() function - users can now simply paste full YouTube URLs, short URLs or just the video ID, and the system automatically handles the extraction.

I have sent v1.0.4 to Zen Cart for review. Your feedback is much appreciated.

could this plugin be used to add videos to banners?
