PHP inside Onclick

realtek

Hello,

Is it possible to place a session_register() inside an HTML Onclick tag.

I would assume it would be something like

Onlick=\"javascript:location.href='blah.php'".(session_register("myvar"))."\"

can anyone advise me of how to make this actually work?

Thanks All!

have a re-read of some of the php beginners stuff.

php is serverside scripting which sends plain text to the browser. As programmers we make sure that text is something the browser understands - HTML, XML etc. When the browser reads the HTML (mostly) it decides what client-side actions to take.

An onclick event is therefore client-side as it happens on the browser and is nothing to do with php. If you want php to do something you will need to submit a form, call a page etc and refresh the content of the screen.

Seing as you have read all of the beginner 'stuff' I can assure you that it is possible, I have created a couple of IF statements and it is fully working now.

If you get stuck on anything let me know and i'll be happy to help.

Thanks anyway

Hi, I agree with sarahk in his idea.
onClick, onMouseOver, etc all this stuff is eventhandlers, it's used only with clientside technologies(things which be processed and manipulated inside the visitor or user machine) such as JavaScript and VB Script. Here PHP is ServerSide Script (things which be processed and manipulated inside the web server machine which you visit) this means any php results the user obtain it, it has already processed and ther's no more to do with it. However, you can make this in the resultant php page to resubmit this data again to the web server again to process it again in another php file on the server(or even the same) and it will send the modified data again to the client browser.
I hope this help you.
