Hello everyone.
I am clueless when it comes to php. I am using the script below to call my images.
my image links look like chimage.php?southington=imagename.gif
what i am trying to do is modify this script to allow me to use multiple directories. As the code sits right now, i can only direct the script to one directory. ($imagedir)
is there a way to make it so i can use multiple directories?
and call my images like so.
chimage.php?southingon=imagename.gif
chimage.php?bristol=imagename.gif
chimage.php?waterbury=imagename.gif
and
?southingon= will point to the directory images/southington
?bristol= will point to the directory images/bristol
?waterbury= will point to the directory images/waterbury
etc. . .
do you get what i am trying to say? im sure its very simple, but like i said, when it comes to php i wouldnt even be considered a newb. I come before that. :p
Thanks for your help!
