Server request uri page and related pages

Question

I'm nearly done with finding a way to show a .html file on certain pages only.

In this case i want test.html to be shown on http://www.example.com/categories/AnyPageThatExcistsInCategories

I figured out the following code works on /categories. <?php if ($_SERVER['REQUEST_URI'] == '/categories/') { include 'test.html';} ?>

I only need the golden tip on how to get it also working on pages like /categories/ThisCanBeAnything and categories/ThisCanBeAnything/AndThisAlso etc etc server config is nginx.

thank you

I'm not sure of your server environment, but if you are using Apache and enable the rewrite module, you could do it that way. — Progrock, Sep 13 '16 at 22:16
Sorry forgot to mention it. Its running on nginx. The code i provided does work perfectly but only on /categories and not /categories/AnythingElse. — razz, Sep 13 '16 at 22:18
You can use rewrite rules under nginx: https://www.nginx.com/blog/creating-nginx-rewrite-rules/ — Progrock, Sep 13 '16 at 22:28
You could use a regex or partial string comparison. See https://stackoverflow.com/questions/4366730/how-to-check-if-a-string-contains-a-specific-word-in-php — Robert, Sep 13 '16 at 22:44
Note: `'\categories'` is a different string to `'\categories\'`. — Progrock, Sep 14 '16 at 09:44

You could see if the request uri begins with the string '/categories/':

<?php

$request_uri = '/categories/foo';

if (strpos($request_uri, '/categories/') === 0 )
{
    include 'your.html';
}

Substitute the value of $request_uri above with $_SERVER['request_uri']. Under the assumption that you have this logic in a front controller.

Further:

<?php

$request_uris = [
    '/categories/foo',
    '/categories/',
    '/categories',
    '/bar'
];

function is_category_path($request_uri) {
    $match = false;
    if (strpos($request_uri, '/categories/') === 0 )
    {
        $match =  true;
    }

    return $match;
}

foreach ($request_uris as $request_uri) {
    printf(
        "%s does%s match a category path.\n",
        $request_uri,
        is_category_path($request_uri) ? '' : ' not'
    );
}

Output:

/categories/foo does match a category path.
/categories/ does match a category path.
/categories does not match a category path.
/bar does not match a category path.

In use:

if(is_category_path($_SERVER['REQUEST_URI'])) {
    include 'your.html';
    exit;
}

You may want to not match the exact string '/categories/', if so you could adjust the conditional:

if(
    strpos($request_uri, '/categories/') === 0
    &&                      $request_uri !== '/categories/'
) {}

For some reason this shows the html on all pages all across the website. ps. "foo" in here `$request_uri = '/categories/foo';` could be anything which i don't know, a digit, a letter, maybe combined. — razz, Sep 13 '16 at 23:06
One assumes you have `$request_uri = $_SERVER['REQUEST_URI']`, instead of the fixed value given above. You'll also want to exit after the include. — Progrock, Sep 14 '16 at 09:18

Progrock's example will work just fine, but here is another example using a regex match instead of strpos, in case you're curious!

<?php
if (preg_match("/\/categories\/.*/", $_SERVER['REQUEST_URI'])) {
    include 'test.html';
}
?>

But in my case, your answer is the only one that works. Thanks everyone for the help. – razz Sep 14 '16 at 09:07
You might want to anchor that regex pattern to the beginning of the string: `"/^\/categories\/.*/"` – Progrock Sep 14 '16 at 09:40
