Somewhat confused about URL Helper - joho - 04-06-2023
I've only been playing with CI for a few days, so forgive me if this turns out to be a case of ignorance or misreading something.
Regarding the URL Helper functions, why is the "CI master-file" (index.php) often included in the output? Wouldn't it be far more useful if I was actually getting URLs back that matched what the browser things/uses? I mean, URL functions are most often used to create an application that is self-contained, to allow for a dynamic configuration scenario (as opposed to hard coding value), no?
My playground environment is https://mydomain.com/ltest
The current section I'm playing with is https://mydomain.com/ltest/subsection
The current route I'm playing with is https://mydomain.com/ltest/subsection/edit
So...
site_url() returns "https://mydomain.com/ltest/index.php"
base_url() returns "https://mydomain.com/ltest"
index_page returns "index.php"
url_to('subsection::edit') returns "https://mydomain.com/ltest/index.php/subsection/edit"
If I were to use any of these returned URLs in, for example, a form, I would still have to manually override things, or force things, which I don't want to. I want the application to be able to figure out what a correct and absolute URL is.
I realize I can do manual replacing, remove "index.php" from the returned data, and so on. But I'm curious as to the reasoning behind the logic that is in place now.
I guess I was thinking more along the lines of these:
$_SERVER['REQUEST_URI'] = "/ltest/subsection/edit"
$_SERVER['HTTP_HOST'] and $_SERVER['SERVER_NAME'] = "mydomain.com"
To have something I could put in a <form method="post" action="..."> to get an absolute (and correct) URL.
I do realize that most "apps" don't live in a sub-directory or "subsection", and that it may be an edge case, but I'd still like to make the app dynamically adjust for this possibility.
Maybe I configured something wrong.
(This is using PHP 8.1.2 with Nginx)
I did find that by exposing 'request_uri' as a parameter from the controller to the view, .e.g.
Code:
$data['request_uri'] => $this->request->getUri()I can do this in the view, so I guess that works better for my purposes.
Code:
<form method="post" action="<?= $request_uri ?>">
..
</form>That gives me the URL I want for the form action, which is https://mydomain.com/ltest/subsection/edit

I'm guessing I'll soon be told to read this: https://codeigniter.com/user_guide/general/urls.html#urls-url-structure
Which would be a fair point. So it probably comes down to me not having wrapped my head around all that yet.

This following code is probably wrong, even if it works in your local PC.
PHP Code:
url_to('subsection::edit')
Because the controller name should be "Subsection", and the file be "Subsection.php".
On case sensitive filesystems, the code would not work.

Probably you already know, but the answer is:
by default, CI outputs index.php in the URLs, because it works without mod_rewrite or rewriting the URL.
But in most cases, we do not use such URLs, and we use rewriting and set Config\App::$indexPage to empty string.

In CodeIgniter url's are always Controller / Method
url_to is used for named routes.
PHP Code:
<?php
// The route is defined as:
$routes->get('users/(:num)/gallery/(:num)', 'Galleries::showUserGallery/$1/$2', ['as' => 'user_gallery']); // the as => is the named route
?>
<!-- Generate the URI to link to user ID 15, gallery 12: -->
<a href="<?= url_to('user_gallery', 15, 12) ?>">View Gallery</a> <!-- user_gallery is the named route. -->
<!-- Result: 'http://example.com//users/15/gallery/12' -->

I think you mean url_to CAN be used for named routes. It can also be used without naming the route. So, in the example you provided
Code:
url_to("Galleries::showUserGallery", 15, 12)Code:
http://example.com/users/15/gallery/12https://codeigniter.com/user_guide/helpers/url_helper.html#url_to
RE: Somewhat confused about URL Helper - InsiteFX - 04-07-2023
In the pass I found that sometimes it helps to use the base_url() method with route_to().
