hitman6003 Posted March 20, 2006 Share Posted March 20, 2006 What your asking doesn't make any sense for the code that you've supplied.Please either explain better, provide more code, or both.

graves_it Posted March 20, 2006 Author Share Posted March 20, 2006 Here is all the code. This is a photo gallery that uses the date to order the pictures. Let say there are 3 picture. When you are on 3 and use $lastpage it goes to ?pg=4 instead of the begeinning ?pg=1.[code]<?$Files = array(); $Files[] = ""; $dirfiles = opendir($dir); $imgcount = 1;$cdate = date("Ymd"); $pg = $_GET['pg'];if (! $dirfiles)die('Can Not Find Any Images' . $dir);while ($Filename = readdir($dirfiles)){ if($datedriven == true) {$fulldate = substr($Filename, 0, 8); }else{$fulldate = 0;} $fulldate = substr($Filename, 0, 8); if ($Filename == '.' || $Filename == '..' || $fulldate > $cdate) continue; $imgcount++; $Files[] = $Filename;}sort($Files);$imgcount = $imgcount-1;if($pg == "" or $pg > $imgcount or $pg < 1){ $pg = $imgcount; }$imagesource = $dir . $Files[$pg];$imageinfo = getimagesize($imagesource);$imageheight = $imageinfo[1];$imagewidth = $imageinfo[0];if($datedriven == true){ $month = substr($Files[$pg], 4, 2); $day = substr($Files[$pg], 6, 2); $year = substr($Files[$pg], 0, 4); $imagecolor = "#" . substr($Files[$pg], 12,6);}else{ $month = ""; $day = ""; $year = ""; $imagecolor = $defaultbackcolor;}$lastpage = $pg +1;if($lastpage < 1){ $lastpage = $imgcount; }$nextpage = $pg -1;if($nextpage < 1){ $nextpage = $imgcount; }?>[/code] Quote Link to comment https://forums.phpfreaks.com/topic/5317-if-statements/#findComment-18926 Share on other sites More sharing options...
