jQuery load php file as text? - php

Is it possible to load a php file as text with jquery?
$('#loader').load('somefile.php', function(e){
console.log(e);
});
This always interprets/execute the php file but I'm looking for a way to only load it as text, without to resort to renaming my php file as .txt
Is it possible?
Cheers

It is not possible without making any server side modification. The web server will always interpret the php file and return the output. However does not matter what solution you find it'll be very dangereous since you'll be dumping content of your php file to public.
Possible solutions with server side modifications:
Create a PHP file that dumps the content of a file, which name is specified by a url argument
Rename the file (I know the op does not want this, just included since it's an option)
As #nicholas-young suggested, get rid of the PHP tags.
I'm not sure why you need this type of need but I want to emphasize that this might not be a good idea in most of the cases since you'll be make a working PHP file available to public. If you can explain more why you need this we might offer better solutions.
Update:
Create a dumper.php that requires authorization and call this file from the javascript side with passing the filename that you want to be dumped as a parameter (dumper.php?file=index.php)
echo file_get_contents($_GET['file']);

It is of course not possibile.
.load will make an HTTP request to yourwebsite.com/somefile.php hence you will obtain the result of your script not the PHP code inside it.
If you really need the raw code inside your javascript as a string you should output it from the php itself:
<script>
var yourCode = <?=json_encode(file_get_contents('somefile.php')) ?>;
</script>

NO! Would be a major security problem if possible. The header will not matter. If making request towards php file, it will execute prior to delivery.
Use some parameter to print out contents from file instead. But do it in the file itself.

Using PHP to create AS2 functions

Is it possible to use PHP to create AS2 functions? Like load the php file from the swf file and have it [the php file] send a string like
function test(){
trace("test");
}
and somehow get AS2 to read it as a function. The reason I want to do this is because I don't want anyone seeing 2 of my good functions in my flash file. I know about SWF Encrypters and things, but none of then can truly keep one out. Thanks.
Sorry for bad grammar or anything wrong with this post - it's 4 am here.
I don't think it's possible. I mean you could make calls in POST from flash and get php to send you back some code. But it would return as String so you'd have to code a sort of parser to transform that string in to real code in AS2, and that could be pretty complicated.
Not sure but you could make the server handle external .as files with PHP. Thus, your .as fiel would run as regular PHP and as far as there is no problem with the Action Script code in it it should be handled by Flash as a regular .as with external code... You can do this in the .htaccess file for example, with a statement similar to this, that adds the .as extension to the PHP5 handler:
AddHandler x-httpd-php5 .as

How to write response to file using php

I wish to write the response of hitting a given url into the href attribute of an anchor tag using PHP. How can I do this?
Here's an example of what I excpect to happen
mylink.com/getdoc?name=documentA
returns a string as a response:
mylink.com/document2012-03-15.pdf
I need to write this response (using PHP into the href attribute as shown below:
Open Document A
(so the above will be the final source of my page.
I think there are a few ways to do what you want. Not all of them will work exactly as you ask for, but the end result should be the same.
Solution one
My first possible solution was already posted by #shanethehat. You could use file_get_contents to call your PHP script via HTTP and get the response.
Solution two
Another possible solution was suggested in the comments of the post by #YourCommonSense. You could simply include the getdoc script in the PHP script that is generating your HTML file, like this:
$_GET["name"] = "documentA";
echo " Open Document A ";
Solution three
Or you could change the way the getdoc script works. You could use a script more like this:
header("Content-type:application/pdf");
header("Content-Disposition:attachment; filename=\"{$_GET["name"]}\"");
readfile($_GET["name"]);
And you keep your link like this: Open Document A . When getdoc.php is called, it will get the specified file and start a file download.
NOTE: you should probably do some input sanitization with this method (removing slashes, making sure the file ends in .pdf, etc) to make sure someone doesn't try to get a file they're not allowed to get.
That's all I'm coming up with at the moment. There might be a more clever way to do it, but hopefully one of these solutions will do it for you. I would try solution 2 or 3 first, and if they don't work out for you, then go with solution 1.
<?php
//get output from URL
$myfile = file_get_contents('http://mylink.com/getdoc?name=documentA');
?>
Open Document A
How to write response to file using php
Noway.
PHP do not process HTTP requests.
You have to set up your web server to do the rewrite.
There are 100500 questions under mod_rewrite tag, you will find the solution easily.
Note that you may wish to rewrite your url to /getdoc.php?name=document2012-03-15.pdf, not one you mentioned in your question

Why is javascript not able to use a javascript variable I declared in a php file?

Hey everybody, this issue has had me stumped for the last week or so, here's the situation:
I've got a site hosted using GoDaddy hosting. The three files used in this issue are index.html , milktruck.js , and xml_http_request.php all hosted in the same directory.
The index.html file makes reference to the milktruck.js file with the following code:
<script type="text/javascript" src="milktruck.js"></script>
The milktruck.js file automatically fires when the site is opened. The xml_http_request.php has not fired at this point.
On line 79 out of 2000 I'm passing the variable "simple" to a function within the milktruck.js file with:
placem('p2','pp2', simple, window['lla0_2'],window['lla1_2'],window['lla2_2']);
"simple" was never initialized within the milktruck.js file. Instead I've included the following line of code in the xml_http_request.php file:
echo "<script> var simple = 'string o text'; </script>";
At this point I have not made any reference whatsoever to the xml_http_request.php file within the milktruck.js file. I don't reference that file until line 661 of the milktruck.js file with the following line of code:
xmlhttp.open('GET',"xml_http_request.php?pid="+pid+"&unLoader=true", false);
Everything compiles (I'm assuming because my game runs) , however the placem function doesn't run properly because the string 'string o text' never shows up.
If I was to comment out the line of code within the php file initializing "simple" and include the following line of code just before I call the function placem, everything works fine and the text shows up:
var simple = 'string o text';
Where do you think the problem is here? Do I need to call the php file before I try using the "simple" variable in the javascript file? How would I do that? Or is there something wrong with my code?
So, we meet again!
Buried in the question comments is the link to the actual Javascript file. It's 2,200 lines, 73kb, and poorly formatted. It's also derived from a demo for the Google Earth API.
As noted in both the comments here and in previous questions, you may be suffering from a fundamental misunderstanding about how PHP works, and how PHP interacts with Javascript.
Let's take a look at lines 62-67 of milktruck.js:
//experiment with php and javascript interaction
//'<?php $simpleString = "i hope this works"; ?>'
//var simple = "<?php echo $simpleString; ?>";
The reason this never worked is because files with the .js extension are not processed by PHP without doing some bizarre configuration changes on your server. Being on shared hosting, you won't be able to do that. Instead, you can rename the file with the .php extension. This will allow PHP to process the file, and allow the commands you entered to actually work.
You will need to make one more change to the file. At the very top, the very very top, before anything else, you will need the following line:
<?php header('Content-Type: text/javascript'); ?>
This command will tell the browser that the file being returned is Javascript. This is needed because PHP normally outputs HTML, not Javascript. Some browsers will not recognize the script if it isn't identified as Javascript.
Now that we've got that out of the way...
Instead I've included the following line of code in the xml_http_request.php file: <a script tag>
This is very unlikely to work. If it does work, it's probably by accident. We're not dealing with a normal ajax library here. We're dealing with some wacky thing created by the Google Earth folks a very, very long time ago.
Except for one or two in that entire monolithic chunk of code, there are no ajax requests that actually process the result. This means that it's unlikely that the script tag could be processed. Further, the one or two that do process the result actually treat it as XML and return a document. It's very unlikely that the script tag is processed there either.
This is going to explain why the variable never shows up reliably in Javascript.
If you need to return executable code from your ajax calls, and do so reliably, you'll want to adopt a mature, well-tested Javascript library like jQuery. Don't worry, you can mix and match the existing code and jQuery if you really wanted to. There's an API call just to load additional scripts. If you just wanted to return data, that's what JSON is for. You can have PHP code emit JSON and have jQuery fetch it. That's a heck of a lot faster, easier, and more convenient than your current unfortunate mess.
Oh, and get Firebug or use Chrome / Safari's dev tools, they will save you a great deal of Javascript pain.
However...
I'm going to be very frank here. This is bad code. This is horrible code. It's poorly formatted, the commenting is a joke, and there are roughly one point seven billion global variables. The code scares me. It scares me deeply. I would be hesitant to touch it with a ten foot pole.
I would not wish maintenance of this code on my worst enemy, and here you are, trying to do something odd with it.
I heartily encourage you to hone your skills on a codebase that is less archaic and obtuse than this one before returning to this project. Save your sanity, get out while you still can!
perhaps init your values like this:
window.simple = 'blah blah blah'
then pass window.simple
You could try the debugger to see what is going on, eg. FireBug

Problem with AJAX and PHP

I have a small problem, I want to load data from a PHP file and put them on a DIV.
Here's the Jquery code
// Store the username in a variable
var jq_username = $("#txt_checkuser").val();
// Prepare the link variable
var link = 'user.php?action=check&username=' + jq_username;
$('div #checkuser_hint').load(link);
So it works! but instead of loading the result (compiled PHP) it loads the PHP code.
If I write the long URL "http://localhost/project..." it doesn't load anything!
Any idea how to do that?
I think you might be accessing your javascript file as a file on your local filesystem, a request to the same directory would go through the filesystem and not through your webserver, processing the PHP into the desired output. This also explains why http://localhost/project for the AJAX call doesn't work: Javascript might be enforcing the same-origin policy on you.
Verify that you're actually accessing this javascript file through http://localhost/ (as opposed to something like file://C:/My PHP Files/ ).
Does the page return anything when you use your browser?
Are you sure it should not be 'div#checkuser_hint' instead of 'div #checkuser_hint' ?
And this looks like the correct way according to the documentation.
var link = 'user.php';
$('div#checkuser_hint').load(link, {'action':'check', 'username':jq_username});
Are you able to access the script manually on your own? (try accessing it via your browser: htp://localhost/...) It may be the case that you're missing your opening <?php and/or closing ?> in the script-file itself.

PHP : Passing a file to a USer defined function

I have a PHP page(registration.php) from where i would submit a file to another form(preocess.php) .So that in the next page that page will send that file as an attachment to an email id. Can i Call a function in another file and pass this file to that function ?
It is some think like passing a stream to a function. (I am not sure .) Can anyone guide me on this ?
Absolutely, just include the file that originally calls the function.
<?php include ('file_with_function.php'); ?>
Should not pass a file around, better to handle it in the background.
store the file
put some id (in worst case the path) into session
forward the user to the next step (process.php)
Better yet to review and refactor the code if necessary to make the processing in one step.
This way you can avoid half-processed things, entry to the processing pipeline in the middle and similar common multi-page form handling problems.
If you're trying to email the file to someone, PHPMailer (http://phpmailer.codeworxtech.com/index.php?pg=methods) has a function addAttachment that works really well.
If you're just trying to process the file in some way, file_get_contents will get the content of the file as a string, which can be useful if it's text. You do, however, need to be careful that it's a small file, otherwise you'll run out of memory pretty quickly.
