Basic HTML rollover with PHP variables for imgs

Hitoshi

Can someone tell me how to do this?
I want to use preset (in php) values for pictures, and then have them used in a HTML onMouseover type script. so basically i end up with being able to put the mouse over an image and it swaps for another one. but the images url is taken from the php code.

Any ideas?

Hi,
you can made an "image loader", a php script that put the requested image on stdout (with right header...)

You can use it in this way:
<img src="getimg.php?id=10" onmouseover="this.src='getimg.php?id=11'">

The getimg.php load any image for given $id number and after header() command echo it on stdout...

see you

JAVASCRIPT is your answer here - php is server side and rollover are all done client side

you can use php to assign image urls to javascritp variables though

I tryed using javascript, but what I want ultimatly is, the image(when mouse over) to be different for each user that uses it. does that make sense?

mystrymaster

yeah you could use php to get the url's for the images and then get them on a per user basis to communicate those url's to javascript

Hitoshi

could u please show me the PHP code to do this? I've been lookin all through my book and i just cant figure it out. there's like... nothing about images in it :S

mystrymaster

where are the images stored?

how do you know what images you want to serve the user?

how do you know who the user is?

Ok, I think it uses sessions but im not sure. What i do know is my login script does this : URL/index.php?user=*&pass=**
is that sessions or cookies? i think its sessions but im not certain. this would be a start.. can u tell me how I do something like this in php? :
.:Your Stats:. 
Officer Name : < CHECK THE PHP> 
HP : <CHECK THE PHP> 
XP : <CHECK THE PHP> 
LV : <CHECK THE PHP> 
RK : <CHECK THE PHP> 
DF : <CHECK THE PHP> 
AT : <CHECK THE PHP> 
LK : <CHECK THE PHP> 
Gold : <CHECK THE PHP> 
Inventory : <CHECK THE PHP>

So, if a user is logged in as Hitoshi and my password is bob, the address will look like this :
URL/index.php?user=Hitoshi&pass=bob

now I want the HTML stats to display whatever the LOGGED IN USERs stats are. how do I do this? and make page content user specific? If I can understand this, it is better because then I can learn the basics before I dive in and learn the images and stuff. I need the variable that determines the user (of which stats its displaying) to be determined by the session..

I hope u can understand this..
