More Random image talk but as a group

ScotC

I'm trying to create a random image script for a header in a CPG-Nuke based website. I've read through the numerous threads regarding pulling random images but they don't quite seem to fit the bill.

The situation I have is I have headers that contain 9 jpgs. Lets just say img1.jpg-img9.jpg

With 3 different headers I have directories

theme\images\headers\1\
theme\images\headers\2\
theme\images\headers\3\

What I'd like to do is generate a random number then inject that random number into all the image references of the header table. This way the randon number references the directory and all the images contained in there will match up.

My theory is this

Pick random number between 1 and 3 (number of directories)
random number chosen is X

Another part that I believe that I must clarify is that with the random number, once established needs to be the same to point to multiple image references. Therefore I'm guessing that the random number will be generated and then assigned to a variable instead of calling for a random number each time I refernce a number. Then that assigned variable can be injected into the img tag reference multiple times. This will all images from the header being pulled from the same directory.

you seem to have the concept down perfectly


$x = rand(1, 3);


echo '<img src="theme/images/headers/'.$x.'/image.gif">';

if possible though, i would try and use background images and style them with css. then all you need to do is change a single stylesheet instead of inserting tedious php code throughout your html 🙂

My only question for clarification would be that of the way the function works.

$x = rand(1, 3); <----- this line establishes the random number. Does this only happen once or any time the .$x. shows up in the code

I'm afraid that if I have
echo '<img src="theme/images/headers/'.$x.'/image1.gif">';
echo '<img src="theme/images/headers/'.$x.'/image2.gif">';
I could end up with a different number pulled. Hence the need for the second step variable. If it is a "compute random # once" then this should work nicely. Thanks for the tip on the background images. Doesn't mean much to me but I will mention it to some of the folks that are more familiar with the package.

why not try it and see for yourself?
part of learning is experimenting.
