[PHP] Nummers aan gallery toevoegen - Softwareontwikkeling

Hallo,

Ik heb hier dus een gallery script die bestanden uit je dir haalt. Nu wil ik bij elk plaatje dat je hebt aangeklikt een vast nummer onder komt te staan. Dus stel je klikt de eerste thumbnail aan, dan komt er in het originele plaatje het nummer 1 te staan en bij de volgende nummer 2.

Ik heb al op PHP.net gezocht naar array en count, maar daar wordt ik niet veel wijzer uit.

Dit is een al reeds bestaand script dat ik wil modificeren:
PHP:
<?php @error_reporting (E_ALL ^ E_NOTICE);
/* --------------------------------------------------------------- *
 * USER SETTINGS
 * --------------------------------------------------------------- */

    /* 
    ** PAGE TITLE (text string)
    **
    ** will appear at the top of the page
    **
    **/
    $page_title    = "Babes";
    
    
    /*
    ** LEFT CONTENT (text string)
    **
    ** Link, description, graphic, etc - will appear in upper left
    **
    **/
    $left_content  = "<a href=\"http://www.logoringtones.net\">Home</a>";
    
    
    /*
    ** RIGHT CONTENT (text string)
    **
    ** Link, description, graphic, etc - will appear in upper right
    **
    **/
    $right_content = "";
    
        
    /*
    ** IMAGE SOURCE (text string)
    **
    ** VIRTUAL PATH to the photo gallery images - NO trailing slash
    ** Images in this directory must be GIF and JPG files with lowercase '.gif' or '.jpg' extensions
    **
    */
    $image_dir     = "babes";
    
    
    /*
    ** NEXT PHOTO (text string)
    **
    ** Defines what will be used as the "Next Photo". Can be image or text
    ** $next_photo = "Next"; will suffice, or get fancy with a custom graphic (and img tag)
    **
    */
    $next_photo    = "Volgende";
    
    
    /* USE_GIFS (bool)
    **
    ** If 'use_gifs' is set to 'TRUE', thumnail images will be displayed
    ** below the large JPEG image
    **
    ** NOTE: Except for their extension, gif files must be named IDENTICAL to JPGs.
    */
    $use_gifs      = true;
    
    
    /*
    ** COLUMNS (integer)
    **
    ** below the large photo, is a grid of all other images in the photo
    ** gallery - $columns defines how many columns this grid will have
    **
    */
    $columns       = 5;
    
    
    /* 
    ** IMAGES (array)   [OPTIONAL]
    **
    ** Array of all image names in the photo gallery. For each
    ** item in this array, there should be a jpg and - if $use_gifs is true
    ** above - a gif.
    ** 
    ** There are a couple ways to do this...
    ** 
    ** [1] Manually create an array (without extensions)
    **     This is the least amount of work for PHP, and a little more work for you:
    **          $image = array( "image_1", "image_2", "image_3");
    **
    ** [2] Manually create an array by copying contents of the directory
    **     A little more work for PHP, easier for you:
    **          $image = array( "image_1.gif", "image_1.jpg", 
    **                          "image_2.gif", "image_2.jpg", 
    **                          "image_3.gif", "image_3.jpg");
    **
    ** [3] Automatically read your image directory
    **     Most work for PHP - easiest for you:
    **          LEAVE $image undefined (comment it out or delete it)
    **
    ** Gif and jpg files must be named with ".gif" and ".jpg" extenstion (with lower case extenstion names)
    **
    **/
    
    //$image = array( "image_1", "image_2", "image_3");

Dan zal je met gdlib daar een cijfertje bij moeten zetten, gewoon in je loopje iedere keer de huidige var daar neer zetten.

En ik zie niet in wat er zo relevant is aan die lap code die je hier neerpoot?

het is hier niet de bedoeling dat je scripts van anderen door je mede PW-ers laat aanpassen. Lees desnoods ook ff de faq door.
