PHP pages don't respect my script..

[manuelgk]

Hello everybody, yesterday I had a problem with a script that I developed about 2 months ago.

The goal of this script is to detect the click events in the links contained in Web pages and, when this happens, the script should modify the URL of the links putting a string of our choice after the original URL.

The code of the script is shown next:

window.onload=function() {
         if(window.frames.length>0){ 
           for(x=0;x<window.frames.length;x++){
   els=window.frames[x].document.body.getElementsByTagName('*');
             for(c=0;c<els.length;c++){
               els[c].onclick=function(){
                 getOnclicks(this);
               }
             }
           }
         }
         else{
           els=document.body.getElementsByTagName('*');
             for(c=0;c<els.length;c++){
               els[c].onclick=function(){
                 getOnclicks(this);
               }
             }
           }
         }
 
function getOnclicks(el) {
         cadena=new String("?COLAB_CLICK=YES");
         var ta=String(el.getAttribute('target'));
         var url=String(el.getAttribute('href'));
         if (el.tagName=="A"){
             alert(el.href=el.href + cadena+ "\nDestino: " + ta);
         }
 }

The problem is that when I try the script in Web pages save locally in my computer it works well (both HTML and PHP pages). But when I try it on pages that are transmitted (and modified on the fly, adding the call to my script), it does not work anymore, what's wrong? should I forget to combine PHP with JS? do I have something wrong in my code? why does my script work in HTML pages and not in PHP ones?

Kind regards

Is it any different in PHP? How do you add it in the PHP page?

[manuelgk]

Well, I'm not exactly modify the PHP, I just put the script calling in the HTML page. So I think my script does not work because the page I have locally is the result of what PHP show us in Web: a HTML page, as you know PHP code is executed in the server side so is not possible to download the code of PHP pages. Thus if I'm right, the script never going to work because the main execution of the Web page is in the server and it shows us the page like a HTML, so if I modify this HTML with any JS, the script call is not going to take any effect in the page, right?
So what can I do? I hope you can give some advices I really appreciate it.
Kind regards

You were right up to this point. The script, if included correctly, can have an effect on the page. Post the code or a link to a test page.

Well, another thing I forgot to tell you, maybe it could be possible the reson I write before about why my script does not work, but I think I can because the navigator show me the HTML and not the PHP. I read something about JS and PHP, and I found PHP can not be combine with JS, is that true?
the call script is like this:

<language script="text/javascript src=".../route"></script>

As I said, I put this in the HTML locally and it works, but in the Web it does not appear.
Thanks

I read something about JS and PHP, and I found PHP can not be combine with JS, is that true?

no.
absolutely not.

php prepares a url for delivery to a browser.
php outputs html, css, and javascript as well.

it is all text to php, and no javascript is executed on a php server.

the browser can;t see the php and the php can't run the js.

As I said, I put this in the HTML locally and it works, but in the Web it does not appear.

Try the HTML file on the web server. Does that work?

[manuelgk]

Before I start I'm really sorry if I answer today.
When I run the HTML in a server the js works but as you told me, PHP doesn't execut a js, now the question is, is there any way to detect the events in a php page (it doesn't matter if it isn't in JS)?
Kind regards

[acoder]

now the question is, is there any way to detect the events in a php page (it doesn't matter if it isn't in JS)?

No, PHP is server-side while JavaScript is client-side. You need a client-side language to detect events.

Can you run any PHP script? Have you got a test link?

[manuelgk]

Well, I'm a little confuse about the PHP script, I think it is something similar to a js but in some pages I read they are PHP pages.
In the other hand, if my idea about PHP scripts is correct, what is the difference beteween make a JS and make a PHP script? does the PHP script is execute in the client side to?
Another think I read in your reply, something about "a client-side language", it means HTML for example, right?
About the links you ask me, the situation is the same, if I have it locally it works but in the internet not, I get the www.laas.fr, the PHP official site and my school page (www.itsx.edu.mx) and nothing happened.
Thanks for everything, please if you don't understad something about I write, please let me know it.
Kind regards
