It's a similar logic for OpenCart 4:
Code: Select all
// event handler for admin/view/catalog/product_form/before
public function eventViewCatalogProductFormBefore( string &$route, array &$data, string &$template_code ): void {
// ....
$code = $this->getTemplateCode($route,$code);
// .... modify $code
$template_code = $code;
}
protected function getTemplateCode( $route, &$code ) {
if (!empty($code)) {
return $code;
}
$file = DIR_TEMPLATE . $route . '.twig';
if (is_file($file)) {
$code = file_get_contents( $file );
} else {
trigger_error("Cannot find template file for route '$route'");
exit;
}
return $code;
}
Thank you for your reply,
I have tested the code but I got error:
Code: Select all
Notice: Cannot find template file for route 'extension/opencart/dashboard/recent_info'
Note I want to edit the this file:
Code: Select all
admin/view/extension/opencart/dashboard/recent_info.twig
Any help!

So does the file 'C:/wamp64/www/oc4024e/admin21/view/template/extension/opencart/dashboard/recent_info.twig' exist?
Perhaps the code should be:
Code: Select all
protected function getTemplateCode( $route, &$code ) {
if (!empty($code)) {
return $code;
}
$file = DIR_EXTENSION.'opencart/admin/view/template/dashboard/recent_info.twig';
if (is_file($file)) {
$code = file_get_contents( $file );
} else {
trigger_error("Cannot find template file for route '$route'");
exit;
}
return $code;
}
Your $route looks strange.

It's working now, thank you so much for your help.
But why it didn't working when use your code and working without your code ??

It's all about the way how the $route is translated into the correct path of the corresponding twig file. OpenCart has a weird way of dealing with extensions

I've updated the above slightly for 4.1.x, though I have yet to get to the correct path for a theme folder as it seems the theme folder name can be different from the config name for themes, where modules can't.
Code: Select all
protected function getTemplateCode($route, &$code) {
if (!empty($code)) {
return $code;
}
$template_file = DIR_TEMPLATE . $route . '.twig';
if (str_contains($template_file, 'extension/ocmod')) {
$route = str_replace('extension/ocmod/', '', $route);
if (defined('DIR_CATALOG')) {
$template_file = DIR_EXTENSION . 'ocmod/admin/view/template/' . $route . '.twig';
} else {
$template_file = DIR_EXTENSION . 'ocmod/catalog/view/template/' . $route . '.twig';
}
}
if (file_exists($template_file) && is_file($template_file)) {
return file_get_contents($template_file);
} else {
trigger_error("Cannot find template file for route '$route'");
exit;
}
}
