number of times requested

[The Little Guy]

I have a PHP file that is being called from other peoples web sites, is it possible for the file to only be accessed one time per page request?

[DjMikeS]

I take it you don't have access to those other sites so you could do something with cookies ? Or perhaps a $_SESSION variable?

[The Little Guy]

You are correct, no access at all.

 

Im not sure how I would do cookies, or sessions with this, any idea?

[DarkWater]

I'm going to have to say that it's not possible.

[The Little Guy]

They call the PHP file from a javascript file that I have, I could put some javascript in that couldn't I?

 

Some thing like when the JS is called set a var to one, and if the var is already set to one don't let the php be included again.

 

Also could I do a require_once, or include_once in the PHP file?

[DarkWater]

1)  They can change Javascript...

 

2)  Not really.

[The Little Guy]

not everyone knows how to change JS, so it would give some protection.

[The Little Guy]

The JS way does work, now is there any way for if someone knows how to edit JS?

No, and it doesn't take a very smart person in order to edit plain text (which is what Javascript is).  =/

[The Little Guy]

Not sure if it matters, but the javascript is in a file on my server not theirs.

[DarkWater]

Ah.  Can I see the contents of it so I know what it's doing?

[The Little Guy]

I give them this code (past onto their server):

 

<script type="text/javascript">
var idNum = '1';
var projectID = '6';
var projectCode = 'eb7sv7vnwc'
</script><script type="text/javascript" src="http://superstats.phpsnips.com/javascripts/stats.js"></script>

 

If they edit it if they they want, but then then they wont be able to see their website's stats.

 

The code that it access looks like this (on my server):

// JavaScript Document
var width=screen.width;
var height=screen.height;
var ref=document.referrer;
var loca=document.location;


var to_str = 'location='+loca+'&width='+width+'&height='+height+'&ref='+ref+'&owner_id='+idNum+'&project_id='+projectID+'&projectCode='+projectCode;
if(!called){
document.writeln('<script language="JavaScript" src="http://superstats.phpsnips.com/javascripts/jsProcess.php?'+to_str+'"></script>');
}
var called = true;

[DarkWater]

Why does it matter how many times they call it?

[The Little Guy]

cause if they place it on their site 50 times, and can modify my JS on the server, then for every person that loads the page, it will add 50 of the exact same thing to the database, it will also give inaccurate stats.

[The Little Guy]

I just set it up to run the JavaScript file through a PHP file, and now that works...

 

Wondering, if I can use PHP to check and see if the Javascript file was requested via URL or by another script, such as the other users Web site....

[kratsg]

The best thing I thought you could do is automatically run AJAX to post parameters to a PHP page about the details of the referrer, etc.. and update the database that way.

 

Since they use javascript to access YOUR javascript, anything you want to do must be written up in your javascript.

 

Hence, by using AJAX, you can:

 

1) update their information on how they've accessed your site

2) check to see if they've accessed too many times, etc...

[The Little Guy]

I was actually able to write a .htaccess file, that take the request and runs it though a PHP file, that way I can check things using PHP....

 

Here is what I have so far...

 

header("Content-type: application/x-javascript");
if(basename(__FILE__) == basename($_SERVER['PHP_SELF'])){
//if($_SERVER['HTTP_REFERER'] == 'http://superstats.phpsnips.com/javascripts/stats.js'){
echo 'No Access!';
}else{
readfile('stats.js');
}

//print_r($_SERVER);
