I have the following files. The objective of this is to redirect to the correct news. For example: localhost/tostadotv/esto-es-una-noticia-28.html
If I intentionally modify the url, for example: localhost/tostadotv/esto-es-una-noticia-modificada-incorrecta-28.html
I should redirect myself to the correct news: localhost/tostadotv/esto-es-una-noticia-28.html
Where this error? Could you please help me thanks. Excuse my english I'm from Argentina I do not speak English

else
$url = SITE_DOMAIN.'/tostadotv/'.strtolower($clean_product_name).'-'.$product_id.'.html';
return $url;
}
As said in the comments, the final solution for the asker was to add http://
to the defined SITE_DOMAIN
constant.
Before
define('SITE_DOMAIN', 'localhost');
After
define('SITE_DOMAIN', 'http://localhost');
But there's more to it than just that. Let's focus on the following two functions:
function fix_category_product_url(){
$proper_url = get_proper_category_product_url(1);
if(SITE_DOMAIN.$_SERVER['REQUEST_URI'] != $proper_url){
header('HTTP/1.1 301 Moved Permanently');
header('Location: '.$proper_url);
exit();
}
}
function make_category_product_url($product_name, $product_id, $ido) {
$clean_product_name = _prepare_url_text($product_name);
if($ido == 0)
$url = strtolower($clean_product_name).'-'.$product_id.'.html';
else
$url = SITE_DOMAIN.'/tostadotv/'.strtolower($clean_product_name).'-'.$product_id.'.html';
return $url;
}
The idea here is that $proper_url
actually ends up getting a value from make_category_product_url()
because its result is returned by get_proper_category_product_url()
. It makes sense because make_category_product_url()
has more parameters and uses the other to get their values.
What's funny about this is that the else
block of the second function doesn't always return a path, but rather a URL. The problem here is that such URL is given without a defined protocol, but starts with the domain name instead. This value is therefore mistaken as a path.
Now take a look at the first function: it ultimately redirects the user using header('Location: '.$proper_url);
. As we discussed earlier, $proper_url
is not always a path , so the protocol should be added somewhere in the code whenever a URL takes place instead of a path. That's where the actual solution comes in: adding http://
where SITE_DOMAIN
is defined is one way to do this, because this constant is only used when a URL takes place. There are many other ways to do this , but this one is completely valid.
