photo gallery

[wds]

i am very new to php, and i have only a basic knowledge/understanding. i am trying to start a photography business, and what i want to accomplish is to be able to dynamically create a gallery. the script will simply look in the folder i specify, display 20 photos per page, and allow the user to click each photo to enlarge it.

 

what i want to know is what function is necessary in order to create the array of images?

 

any other information/snippets which pertain to my goal would be appreciated. i've been searching the forum but have yet to find a similar post in relation to what i am trying to obtain.

 

thanks,

glob()

<?php
$i = 1;
foreach(glob('/my/image/dir/*.jpg') as $imageName){
     if($i<20){
          echo '<img src="'.$imageName.'">';
     }else{
          break;
     }
     $i++;
}
?>

how can i go about logging what page in the gallery i am in to determine which images to display?

 

for instance lets say i have 100 images, when you first open the gallery, it display images 1-20, then when i click "next" it creates another page displaying images 21-40. i'm trying to figure this out using a form with the "get" method but as i said before, i am not well versed.

 

ideas?

 

furthermore, how can i increment/decrement a variable when the button is pushed?
