i am new to a php site, only familiar with .net web forms sites.
i can't figure out how routing is working on this php site.
www.oursite.com/suggestions.php is to suggestions.php
www.oursite.com/suggestions also loads the php fine
www.oursite.com/suggestions/ loads the php, but no css is applied
www.oursite.com/suggestions/anything - anything that comes after the '/' is ignored and suggestions is loaded without css. so oursite.com/suggestions////// works, as does oursite.com/suggestions/2/2/2/2/whatever
i have searched but not found any good explanation on how this is working. can someone explain or provide a good resource?
thank you.
This is most certainly done using Mod_Rewrite, an Apache extension. You'll probably find a file called .htaccess in the public root, in which these rewriting rules are defined.
DouweM has the right answer as far as the friendly urls are concerned.
As for the CSS, it is probably because you are using relative URLs in your link tags:
<link rel="stylesheet" href="site.css"/>
Change those to absolute URLs and it should solve that problem:
<link rel="stylesheet" href="/site.css"/>
The reason for this is that the browser makes the request for the CSS based on the directory it thinks it is in, even though your URL rewriting is changing that. So, if the url is http://mysite.com/suggestions/ and you are using relative urls, the browser will request the css as http://mysite.com/suggestions/site.css which of course doesn't exist.
www.oursite.com/suggestions.php is to suggestions.php
www.oursite.com/suggestions also loads the php fine
You probably have a .htaccess file that first checks whether or not a file of that name exists, and if it does serves it, then, if it doesn't, tries to route it to a php script.
www.oursite.com/suggestions/ loads the php, but no css is applied
The / means your browser considers '/suggestions/' a directory. If suggestions.php outputs HTML that contains a relative <link> to a stylesheet, e.g. <link href="style.css">, your browser will request www.oursite.com/suggestions/style.css, rather than www.oursite.com/style.css as in the previous two cases.
www.oursite.com/suggestions/anything
Same as the previous case, your browser will request the wrong css file, since it considers '/suggestions/' a directory. (For a potential fix, take a look at Eric Petroelje's answer.)
As DouweM said, though, your best bet is to look directly at your .htaccess file and figure out what it does.

I'm aware that doing so in HTML is as simple as this:
<link rel="icon" href="/favicon.ico" />
However, I have a PHP site, in which:
DirectoryIndex index.php
to direct the user directly to the main page.
I can't seem to find a way to get a browser tab icon.
What have I tried?
I tried to echo HTML inside index.php with the code, which didn't work. I also tried placing the line of code in some other working header HTML from within index.php. Google has nothing... literally.
The image is a .ico, called 'favicon.ico', is in root, and is recognized as a valid ico file.
Any help?
By default, you actually don't need anything in your HTML for a favicon. Simply having a valid favicon.ico in your root should be enough.
Sometimes, when changing favicon you need to clear your browser cache for that site. Also, try accessing the favicon.ico directly: http://example.com/favicon.ico and make sure you can load it.
Here's a good resource about favicons: HTML 5 Favicon - Support?
I wanted to pass the parameters to my PHP page in a friendly fashion, so here's what I wrote in .htaccess file
RewriteRule ^confirm\/(([a-z0-9]).+)\/(([a-z0-9]).+)$ www.example.com/confirm.php?email=$1&order=$2
its working well, and I can get the parameters in PHP using
explode('/', $_SERVER['REQUEST_URI'])
I have 2 problems though,
1- when I submit this page, I need it to go directly to confirmation.php, instead it submits to www.example.com/confirm/example#mail.com/12-HDYF/confirmaction.php !!! how can this be changed.
2- the page was originally working perfectly, but when I type the friendly URL all jquery files give me the below error, which really seems unrelated.
That is because the client (the browser) sees the page it is browsing as www.example.com/confirm/example#mail.com/12-HDYF/ and when it analyzes it and parses the html, it sees it something like:
<script src="jquery.js"></script>
<form action="confirmation.php"... >
So the browser sees relative urls to the page he is at the moment. So if you tell him to search the jquery.js file in the same folder as the one he currently is, he is going to try to download from www.example.com/confirm/example#mail.com/12-HDYF/jquery.js, and the same thing happens when you submit the form.
To avoid this, use absolute URLs (note the leading slash):
<script src="/jquery.js"></script>
<form action="/confirmation.php"... >
If you have your files in a subfolder of the DocumentRoot, put that subfolder at the beginning of the URL.
Change your url structure to avoid ^confirm for both raw and friendly URL, that should make things easier to debug (and avoid loops). This is a guess since you haven't posted your input that fails.
RewriteRule ^orderconf\/(([a-z0-9]).+)\/(([a-z0-9]).+)$ www.example.com/confirm.php?email=$1&order=$2
I have a php file that loads an article from a db based on the given variables. There is also an .htacces file in the root of the site. I used this in the htaccess to redirect
RewriteRule
^articles/([a-zA-Z0-9-_\s]+).html$
template/index.php?action=viewarticle&alias=$1
after redirecting, the page shows fine but the html in the page goes wrong, for example:
media/2011/02/21/logos.jpg turns in to articles/media/2011/02/21/logos.jpg
This happens because the htacces is redirecting. Is there anyway to do this redirect while keeping the root dir unchanged?
This happens coz the htacces is redirecting.
No, this happens because the browser thinks that
example.com/articles/my_article.html
is a resource in the /articles sub-directory, and treats all relative URLs as relative to /articles.
There is no way to change that behaviour.
You will need to start using absolute image references, or relative image references that consider the additional directory:
<img src="/media/2011/02/21/logos.jpg"> <------ recommended
<img src="../media/2011/02/21/logos.jpg">
you could also use <base> as suggested by #Boris but absolute paths (or full URLs) are a vastly cleaner solution to the problem in my opinion.
First, what do you mean by "html in the pages goes wrong":
Is it the link showed in the status bar?
Is it the actual href? If it is, you probably use some view helper which construct your "base url"
Maybe you "link" your resource without specifing an absolute path (using /), then your resource are "relatively" linked to current page (/articles/)
.htaccess don't change anything in your code.
There is an html element which allow you to define base url used everywhere in your page.
<base href="/root" />
if you have for example Article 12 then when clicking on the link, you will redirect to /root/articles/12
Also, mixing Pekka's answer with Boris', you should define somewhere in your application which is the root path of your application and output all paths as absolute, prepending the base dir you defined earlier.
for example: in config.inc.php
define("ROOT_URI", "http://myserver.com/myapp");
everywhere:
<img src="<?php echo ROOT_URI;?>/media/2011/02/21/logos.jpg
This is like using the base element as Boris suggested, without using it (I also dislike base), and makes your application able to work in whatever folder under the webserver it is stored.
I haven't found a clear answer to this question (but have determined the HTML tag is more trouble than it's worth.)
When you're working with multiple directories on a website, how do you make sure relative links to the rest of your site work as you change your current directory? I don't want my link to "/index.php" to actually link to "/support/index.php" when I go to the support directory.
We're using PHP, so I could use output buffering to change links, but I want to see if others have any good ideas. Could also implement it through Smarty in one way or another. I haven't built a website from scratch that has used multiple directories simply because I don't know of an easy way to deal with this, but the problem shouldn't be too difficult.
(Running on IIS, but obviously it would be better to let it work on any server.)
you could declare a base_url variable, or declare a constant containing your base url
e.g.
DEFINE('BASE_URL', 'http://example.com/');
when using links
e.g.
Home
You already have everything you need
how do you make sure relative links to the rest of your site work as you change your current directory?
we're using absolute links for that
I don't want my link to "/index.php" to actually link to "/support/index.php" when I go to the support directory.
Lucky you, it will never happen
/index.php is absolute path and will never point anywhere beside /index.php.
/ is not just for decoration. It the meaning of slash at the beginning of the path is "root directory". So, /index.php means index.php placed in the root directory.
/support/index.php means index.php placed in the support directory which is placed in the root
easy-peasy. just always use absolute path (not URL which is senseless)
I store a “base” URI in two locations: (i) on the PHP/Zend Framework server, my configuration.xml file holds conventional values such as URIs; (ii) on the client side a more shallow, hidden <form/> holds other (less security compromising) values such as a base URI.
The form, by the way, looks something like this:
<form id="AppSettings" action="#">
<input type="hidden" id="MyBaseUri" value="http://superuser.com"/>
</form>
Add <base href="http://www.domain.com/"> to your <head> tag. This will make all relative links start from the directory given as href. Then use relative links like support/index.php not beginning with/ (i.e. not /support/index.php)
Note: Make the <base> tag the first tag in your <head> section, as all links after that will be interpreted from that base dir. (e.g. <link href="relative/path"> will already use the base dir if it is defined above.
Advantage: you can move your whole page to a subdirectory like http://www.domain.com/page and only have to change the <base> tag. If you use links like /support/index.php they will always start from the root directory (i.e. http://www.domain.com/)
Dynamic base dir for url rewrites:
<?php
if (preg_match("/https/i",$_SERVER["SERVER_PROTOCOL"]))
$protocol = "https";
else
$protocol = "http";
echo '<base href="'.$protocol.'://'.$_SERVER["HTTP_HOST"].dirname($_SERVER["SCRIPT_NAME"]).'/">';
?>
I'm developing a PHP website that uses url routing. I'd like the site to be directory independent, so that it could be moved from http://site.example.com/ to http://example.com/site/ without having to change every path in the HTML. The problem comes up when I'm linking to files which are not subject to routing, like css files, images and so on.
For example, let's assume that the view for the action index of the controller welcome contains the image img/banner.jpg. If the page is requested with the url http://site.example.com/welcome, the browser will request the image as http://site.example.com/img/banner.jpg, which is perfectly fine. But if the page is requested with the url http://site.example.com/welcome/index, the browser will think that welcome is a directory and will try to fetch the image as http://site.example.com/welcome/img/banner.jpg, which is obviously wrong.
I've already considered some options, but they all seem imperfect to me:
Use url rewriting to redirect requests from (*.css|*.js|...) or (css/*|js/*|...) to the right path.
Problems: Every extension would have to be named in the rewrite rules. If someone would add a new filetype (e.g. an mp3 file), it wouldn't be rewritten.
Prepend the base path to each relative path with a php function. For example:
<img src="<?php echo url::base(); ?>img/banner.jpg" />
Problems: Looks messy; css- and js-files containing paths would have to be processed by PHP.
So, how do you keep a website directory independent? Is there a better/cleaner way than the ones I came up with?
You could put in the head
<base href="<?php echo url::base(); ?>" />
This will mean the browser will request any non-absolute URLs relative to that path. However I am not sure how this would affect URLs embedded in CSS files etc. This does not affect paths defined in CSS files. (thanks mooware)
The <base> thing will work but you need to remember it's going to affect your <a> tags too. Consider this example.:
<!-- this page is http://oursite.com/index.html -->
<html>
<head>
<base href="http://static.oursite.com/" />
</head>
<body>
<img src="logo.gif" alt="this is http://static.oursite.com/logo.gif" />
this links to http://static.oursite.com/login which is not what we wanted. we wanted http://oursite.com/login
</body>
</html>
If you use a PHP function call for creating your links, that won't be a problem as you can just make sure it spits out absolute URL. But if you (or your designers) hand-code the <a> tags then you're stuck with the same problem again, just now with <a> instead of <img>.
EDIT: I should add the above paragraph is assuming you serve images from a different host name like we do. If you don't then obviously that won't be a problem.
tomhaigh has a good point, and would be worthwhile to investigate it further.
According to MSDN, the base tag works for all external sources, including style sheets, images, etc.
Perhaps I'm missing something, but can't you just do what I (and I thought everybody else) do/es? Namely put all your images, css, javascripts, etc in a common directory i.e.:
/inc/images/
/inc/css/
/inc/javascript/
etc
And then reference them with base-relative URLs, i.e.:
<img src="/inc/images/foo.jpg" />
etc
?
