Using $_GET with dots in the URL

[mlk]

Hello there, I've got a little problem (i'm sure the answer is easy, but google didn't help)

Using the following URL: http://127.0.0.1/test.php?image.x=23&image.y=12, how can I possibly get the x and y values of 'image' ?

I've tried $_GET['image'], $_GET['image.x'], $_GET['image']['x']... But can't seem to find the answer, it mostly answers

Notice: Undefined index: t in...

thanks for your help !

why don't you just change the names of your variables?

it's not the name of the variable ... its an image button, it returns w/ x-y coordinates of the click. I had this problem too a while back, can't think of what i did. Let me try to find my stuff and i'll get back to ya.

[edit]

what you do is use _x ...


$_GET['image_x'];

Since (.) periods are illegal in varialbe names in php, it converts 'em to (_) underscores

wow thanks !

If we could give out points to useful people, I'd give you a lot of them ! (and then you could hopefully exchange them to buy some cool geek gear on ebay or such)

too bad i'm not a geek ...

And Also a quick note on the subject:
If you pass a variable with a space in the name ... it also gets converted into an underscore.

cool, I knew about the space conversion but not the period. Useful info antisip:P
