php_beginner_83 Posted April 29, 2009 Share Posted April 29, 2009 Hi All Can anyone help me with this..please. I'm still pretty new to PHP and am slowly figuring it out. I have a photo gallery, that you can navigate through the pics to view each one using 'Next' and 'Previous' links. I want to include this in a website I'm creating. On the website's main page I have a menu. On the menu is the option to select 'Photos'. When you select this, the file that creates the photo gallery is included. However, when I click the 'Next' link to move through the photos, it disappears. Can anyone explain to me why this happens and how I can fix it. Thanks much. My website code is.... <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="text/javascript" src="sclMenu.js"></script> <style type="text/css"> // css styles here </style> </head> <body bgcolor="#000000"> <div id="header"> <img src="Banner_USA.jpg" alt="header image"> </div> <div id="menuNav" > <ul id="dd"> <li><a href="#" class="menu" id="mmenu1" onmouseover="mopen(1);" onmouseout="mclosetime();">Home</a> <div class="submenu" id="menu1" onmouseover="mcancelclosetime()" onmouseout="mclosetime();"> <a href="menu_2.php?page=main">Sights</a> <a href="menu_2.php?page=photo">Photos</a> <a href="#">Test 3</a> <a href="#">Test 4</a> </div> </li> <li><a href="#" class="menu" id="mmenu2" onmouseover="mopen(2);" onmouseout="mclosetime();">New York</a> <div class="submenu" id="menu2" onmouseover="mcancelclosetime()" onmouseout="mclosetime();"> </div> </li> <li><a href="#" class="menu">Memphis</a></li> <li><a href="#" class="menu">Nashville</a></li> <li><a href="#" class="menu" id="mmenu3" onmouseover="mopen(3);" onmouseout="mclosetime();">San Francisco</a> <div class="submenu" id="menu3" onmouseover="mcancelclosetime()" onmouseout="mclosetime();"> <a href="#">Office</a> <a href="#">Sales</a> <a href="#">Customer Service</a> <a href="#">Shipping</a> </div> </li> </ul> </div> <div id="content"> <?php // you build an array for the pages you have. $index = array( "main" => "Sights_text.php" , "photo" => "My_Try_At_Album.php" ); if ( !empty( $_GET["page"] ) ) { $page = $_GET["page"]; if ( array_key_exists( $page , $index ) ) include( $index[$page] ); } ?> </div> </body> </html> And the code for my photo gallery is... <?php // directory where photos are kept $directory = 'images/thumbnails/'; $photos = array(); if($handle = opendir($directory)) { while(false !== ($file = readdir($handle))) { if ($file != "." && $file != ".." ) { $photos[] = $file; } } closedir($handle); } $imgIndex = $_GET['img']; if(!isset($photos[$imgIndex])) { $imgIndex = 0; } $currentImage = $photos[$imgIndex]; if ($imgIndex<=0) { $prev = "Previous"; } else { $prev = "<a href=\"".$_SERVER[php_SELF]."?img=".($imgIndex-1)."\">Previous</a>"; } if ($imgIndex>=(count($photos)-1)) { $next = "Next"; } else { $next = "<a href=\"".$_SERVER[php_SELF]."?img=".($imgIndex+1)."\">Next</a>"; } ?> <html> <body> <?php echo "$prev $next<br>"; echo "<img src=\"{$directory}/{$currentImage}\">"; ?> </body> </html> Quote Link to comment Share on other sites More sharing options...
ignace Posted April 29, 2009 Share Posted April 29, 2009 Read this tutorial: http://www.phpfreaks.com/tutorial/basic-pagination It tells you how you can properly add pagination. This also works for galleries. Quote Link to comment Share on other sites More sharing options...
php_beginner_83 Posted April 29, 2009 Author Share Posted April 29, 2009 I read that tutorial and it doesn't really help me. It gives an example and talks through it but that's it and I seem to be doing something pretty similar. I need help with my code. Can you see anything that's wrong with it. I appreciate the help.
