Hook: on_template_footer_js
The on_template_footer_js hook allows developers to inject JavaScript into the footer of the template.
This is useful for adding custom scripts, analytics, or plugin-related JavaScript dynamically.
Usage
$footerJS = DynamicHooks::executeHook('on_template_footer_js', true);
if (!empty($footerJS)) {
echo implode("\n", $footerJS);
}
This hook aggregates all registered JavaScript callbacks and outputs them at the end of the template.
Example Implementation
DynamicHooks::addHook('on_template_footer_js', function () {
return ['your_javascript_file'];
}, 'custom_plugin');
Best Practices
- Ensure scripts added through this hook are essential and lightweight to prevent performance issues.
- Use unique namespaces for plugins to avoid conflicts.
Troubleshooting
- Check if the script is being added by verifying the namespace and hook registration.
- Ensure the script URL is accessible to avoid 404 errors.
