Javascript messing with PHP

[Boltrig]

Is it common that javascript messes with PHP?

Ive been trying to put bidvertiser ads onto my site, but whenever I do it moves my PHP shoutbox to wherever the javascript is, and puts the ads onto the PHP script location!

Any ideas on how to resolve this?

Thanks in advance guys

If you post what it looks like before, after and the code, then someone can probably help you out, other than that it's difficult to give you an answer.

Umm, it seems to have straigtened itself out.

Not sure what caused it. But still, just as a theoretical - does javascript tend to bugger up other scripting languages?

JavaScript can never touch actual PHP.

The only thing JavaScript can do is output stuff that can change the position of things on the page, or change HTML

Are you for serious? Or just don't know much javascript?

DFox is right.

Javascript is client side, PHP is server side, they never directly interact with each other.

Although the text PHP produces could certainly interact with the javascript

Huh?

I hope you don't actually think JavaScript can modify PHP... JavaScript is a client side language. PHP is server side. Unless you've invented a new kind of JavaScript that runs server side then there's no way...

Xactly.

But at that point it's not PHP, it's HTML :)

Javascript can interact with the server, it's all these fancy new AJAX tricks... I don't know much about it, but it is possible. Google Chat uses JS for such a thing.

Erm, unless your div or whatever has the same class/id as the ads you were inserting, JS couldn't have done anything to it. No, not even with AJAX.

True. But I was talking about javascript having some server side operations, not that JS could manipulate PHP. JS can manipulate the output of PHP though.

[elbekko]

Yes, but not the output of the page you're on (unless you want some fancy infinity looping ;)).

JavaScript can't interact with the server. With AJAX, JavaScript CALLS a PHP or server-side script just like the browser would...

So the AJAX calls the PHP script which simply outputs text that is interpreted by the client side browser. They never physicaly interact. It's input from browser -> POST or GET to server side script -> output from PHP script as HTML or text.

Correct. I think most people fail to understand that Javascript is a part of your browser. It's good to think of it that way because then it's easy to see what Javascrpt can and cannot do. Thinking of it like this can answer a lot of questions plain and simple, with no fuzzy areas.

For instance, Javascript never interacts with PHP, period. Javascript sends a call to the browser to read a URL, that's all. All of the XMLHTTP stuff is just to create a variable and store it's value.

Think of it like this:

Your browser is the parent and Javascript is the child who has to ask the parent (browser) to do everything. Javascript is a pussy.
