In one of the applications that I am working on for my company, I came across a weird behaviour or maybe it's just my misunderstanding and I hope I can get some clarification.
The application is served by Apache and the root is : /company/client. For every page that I visit, for example https://11.11.11.11/index.phtml, it will actually point to the file in the server /company/client/index.phtml and so on. In one of the modules of the application, it contains a move_uploaded_file php function, and the target directory is /images/example/, when the page is run, the app is trying to go to the absolute server root /images/example/ instead of /company/client/images/example/.
Also the a new windowed opened up by window.open has an img tag having src='/images/exmaple/', this points to the server root instead of /company/client/images/example/, is this expected?
Am I missing anything, or is it something to do with Apache configuration?
Additional info:
The application is served as a virtual host in conf file, with DocumentRoot "/company/client/".
The page that is executing window.open and php function is used as an Iframe inside /company/client/index.phtml
sorry for my mistake.
Thanks for the help from the everyone especially Chris G, the problem was that the code is using a GET variable incorrectly, as a result the image name isn't passed. And I got confused because someone made a mistake in the code by moving image relative to the root folder which is incorrect. That made me think that PHP is also treating path like the client side which is a mistake. I'm guessing I can conclude that the web server document root only applies to everything client side, like the url, JS, HTML?

I am going to deploy this page on an FTP
And I need to find out how I can detect the html file currently being viewed using JavaScript.
If I open the html file, it works just fine with this:
var fileName = location.href.substring(location.href.lastIndexOf("/") +1);
But, if I open it via my localhost adress, it has a null value. So I'm guessing I have to use some other method to extract the current html file name. Or is there a better approach to this?
Note: I am not going to use JQuery or anything like that.
EDIT:
I can get the filename if it isn't my index file.. If it's the index file I get nothing using the above code. Most likely since all I have in my adress bar is the localhost adress of the live-server?
The web deals in URLs, not file names.
Sometimes a URL will include something that looks like a file name, and sometimes that even maps on to a real file name on the server's hard disk.
When you type http://example.com/ then it might map that onto a file called index.html. Or maybe on to index.php. Or maybe it won't touch any file but will just use logic built into the web server application to determine what to respond with.
There's no way to know in the general case.
If your specific case, you know that the path / maps onto index.html, so you can write an explicit mapping in your JavaScript code.
When working on a handlebars demo, I am noticing that the stylesheet does not show up when viewing the page. I have provided links to the code and the live page below. Does anyone know why the stylesheet isn't working?
The code is here:
https://github.com/sutri001/DA670/tree/master/week7_handlebars
The live page is here:
http://67.205.184.187:1000
Your rendered page does have the link tag that references the stylesheet you're looking for. What's happening is your server is throwing a 404 when a request is made for the stylesheet.
Looking at the code for your express server, I see you're telling express to serve files staticly from the public directory (good)... but you don't have a public directory, and even more your css directory is located outside of such a place.
My advice is to move your css directory into a new public directory (so you'll have public/css/style.css). That should resolve your issue.
Also, remember that it's the browser that's handling your link tags, not the server! That means browsers are currently trying to go to http://yoursite/../../css/style.css. Thankfully your browser understands how to handle this, but this is definitely not what you want.
Your link tag's href attribute should be set to /css/style.css because, from the browser's perspective, that's where the stylesheet is located.
Versions of this question have been posted numerous times, but none of the solutions I've found on this site have worked so far. I'm trying to redirect away from files, not web pages. I actually need to know if this is even possible, since I learned that PHP is incapable of doing this. Here's an answer from a previous question I asked:
The web server will first check if it exists and if it does, it will serve the file immediately. It does not go through any PHP code. Therefore you cannot write any PHP code that will intercept this request and block it.
We have a folder on our site with a path of /downloads/, containing files we don't want just anyone to download.
I want to put a script in our main JavaScript file that says:
If file is is /downloads/
If user comes from referrer allowed_domain.com, allow access to files in /downloads/
Else redirect to homepage or 404
My attempt (didn't work)
if (top.location.pathname === '/downloads/private.zip') {
if (document.referrer !== "http://www.allowed_domain.com") {
document.location.path = "/downloads/private.zip";
}
else {
document.location.path = "/404";
}
}
Constraints
I cannot use .htaccess. Our hosting provider is running Nginx, not Apache. I've tried using Nginx config code, but I have to send it to them to implement, and it didn't work and they won't help me.
And yes, I know that this is a super, super insecure solution for restricting access. My company is working on a more formal solution, but until then, I need to implement something temporary to deter users who lack the computer knowledge or motivation to get around the redirect, and this is pretty much my last option.
This problem is not solvable in JavaScript, even in the very limited and insecure way that you are proposing. The problem is that a request to /downloads/private.zip directly returns the contents of that file - it doesn't load any HTML page, so the browser will never see or execute that JavaScript code.
A way to solve this would be to have a PHP file that handles any request to that directory, checks whether the user has permission to see those files, and then returns the requested file or a 404. But for that you need some form of configuration, and you've already told us you can't do that either.
A third solution, one that is very silly but would work (for unsavvy users) in this very constrained situation would be to replace all links to the forbidden resources with a snippet of JavaScript that directs the user either to the file or a 404 page. However, from your question it seems very likely that you're trying to prevent access from users coming from sites outside of your control, in which case this won't work either.
Bottom line: This is not a solvable problem if you don't have the ability to configure your web server.
I have following url to be build,
http://localhost/myweb/cart/index.php
I want to get the http://localhost/myweb/ bit build dynamically.
To do that on my live web site which is http://www.myweb.com/cart/index.php I can use the following JavaScript code,
var http = location.protocol;
var slashes = http.concat("//");
var host = slashes.concat(window.location.hostname);
But how do I get my development environment to work since it has http://localhost/myweb/? If I run the above code it will give me http://localhost/ only.
Any suggestions?
window.location.pathname is the thing you search for.
I would suggest you to read the MDN description of window.location. Like everything else in MDN, this is also really straightforward and informative.
If you know that the URL has an unnecessary index.html part at the end you can:
var path = window.location.pathname.split('/');
path.pop();
path.join('/');
or you can slice it (since it is generally faster):
path.slice(0,path.lastIndexOf('/')+1)
EDIT:
Seeing your new question I can say that what you want can't be done consistently and safely by only the current URL.
You need the http://localhost/myweb/ part, which is the URL root of your application. In javascript you are able to get the protocol and domain of the url. On your live site these 2 match, but if your application resides in a subfolder (like the myweb folder at your localhost), this will fail.
What you need is to somehow identify the application URL (the URL root of your application).
The problem is that by only examining the URL, javascript cannot tell where your application resides.
Let's say you deploy your site to: http://localhost/myweb/site1/
You will have the following URL: http://localhost/myweb/site1/cart/index.php
Javascript can split your URL by the slashes (/) but it has no way of nowing how many subfolders it should select. For example from the URL above your application root can be any of the following: http://localhost/, http://localhost/myweb/, http://localhost/myweb/site1/, http://localhost/myweb/site1/cart/.
By an other approach (which I suggested first) you can drop the end of the URL (in your case the cart/index.php part). This will only work if your URL structure IS very rigid, so all the pages this script is executed on reside in one subfolder.
So it will break on the following URL: http://localhost/myweb/site1/gallery/old/index.php or similar.
Your best bet would be to make this a "config variable" in a separate file which you edit on every location it is deployed to.
Either as a PHP variable ($appRoot = "http://localhost/myweb/") which you generate the javascript with.
Or more simply a javascript variable (var appRoot = 'http://localhost/myweb/'). Make a separate js file, call it something like config.js, add the above line to it and reference it before your other javascripts.
I am trying to use jquery's ajax $.get(...) function to send a request to my server and have it return some data. I am using the following code:
$.get("php/getRocks.php", { name: "John", time: "2pm" },
function(data){
alert("Data Loaded: " + data);
});
Instead of getting the the data back, it just returns the entire php file as a string. Am I doing something wrong? Thanks for the help.
Is PHP installed on your server? This is a server issue. For some reason your .php file isn't being handled properly and it is returning the PHP code in plain text.

Thanks to everyone for the help!
When working locally (and it always is a good idea to do so before uploading to a live environment) you need to setup PHP on your computer so that it can run the pages you require. A browser will not do it for you as it is a server side technology. You can download a package like Uniform Server, that will give you a full server environment for you to work with.
I have the same problem (using MAMP on mac), and while I haven't solved it, I am a step closer.
Basically, it would appear to have something to do with subdirectories/document root. If I set my url as getRocks.php (and move my script there), it works (I get content back), but if I get it as php/getRocks.php, it does not work (I get the php code back).
Perhaps MAMP is doing something add with response types within subdirectories? Am going to take a further look, but hopefully this helps lead you in the right direction.

1st. make sure you have php installed
If you are using linux / apache2 and php 5
u need to compile/install apache and load php via dso
eg:
LoadModule php5_module modules/libphp5.so
In my humble opinion it has got nothing todo with your jQuery but your web server installation/config:
If it is apache make sure you add this line in your conf file:
AddType application/x-httpd-php .php
More reading about php and apache if you are using php anad apache in linux/nix eg: http://dan.drydog.com/apache2php.html
