Hi, I'm having problems with my photo gallery code. My php script is in :
C:\wamp\www\
and the images are stored in:
C:\wamp\www\Pictures\DelMarVaFlood
My problem is that the pics don't get displayed and no error message is generated either. However, the code works very well if all images were stored in same directory as the script. Here's my code:
<?php
$columns = 5;
$thmb_width = 120;
$thmb_height = 80;
function resizeImage($originalImage,$toWidth,$toHeight){
// Get the original geometry and calculate scales
list($width, $height) = getimagesize($originalImage);
$xscale=$width/$toWidth;
$yscale=$height/$toHeight;
// Recalculate new size with default ratio
if ($yscale>$xscale){
$new_width = round($width * (1/$yscale));
$new_height = round($height * (1/$yscale));
}
else {
$new_width = round($width * (1/$xscale));
$new_height = round($height * (1/$xscale));
}
// Resize the original image
$imageResized = imagecreatetruecolor($new_width, $new_height);
$imageTmp = imagecreatefromjpeg ($originalImage);
imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0,
$new_width, $new_height, $width, $height);
return $imageResized;
}
function generateThumbnails(){
global $thmb_width,$thmb_height;
// Open the actual directory
if ($handle = opendir("Pictures/DelMarVaFlood")) {
// Read all file from the actual directory
while ($file = readdir($handle)) {
// Check whether tha actual item is a valid file
if (is_file($file)){
// Check whether the actual image is a thumbnail
if (strpos($file,'_th.jpg')){
$isThumb = true;
} else {
$isThumb = false;
}
if (!$isThumb) {
// Process the file string
$dirName = substr($file,0,strpos($file,basename($file)));
if (strlen($dirName) < 1) $dirName = '.';
$fileName = basename($file);
$fileMain = substr($fileName,0,strrpos($fileName,'.'));
$extName = substr($fileName,strrpos($fileName,'.'),
strlen($fileName)-strrpos($fileName,'.'));
// Check if the actual file is a jpeg image
if (($extName == '.jpg') || ($extName == '.jpeg')){
$thmbFile = $dirName.'/'.$fileMain.'_th.jpg';
// If a thumbnail dosn't exists tahn create a new one
if (!file_exists($thmbFile)){
imagejpeg(resizeImage($file,$thmb_width,$thmb_height)
,$thmbFile,80);
}
}
}
}
}
}
}
function getNormalImage($file){
$base = substr($file,0,strrpos($file,'_th.jpg'));
if (file_exists($base.'.jpg')) return $base.'.jpg';
elseif (file_exists($base.'.jpeg')) return $base.'.jpeg';
else return "";
}
function displayPhotos(){
global $columns;
generateThumbnails();
$act = 0;
// Open the actual directory
if ($handle = opendir("Pictures/DelMarVaFlood")) {
// Read all file from the actual directory
while ($file = readdir($handle)) {
// Check whether tha actual item is a valid file
if (is_file($file)){
// Check whether the actual image is a thumbnail
if (strpos($file,'_th.jpg')){
++$act;
if ($act > $columns) {
echo '</tr><tr>
<td class="photo"><a href="'.getNormalImage($file).'">
<img src="'.$file.'" alt="'.$file.'"/></a></td>';
$act = 1;
} else {
echo '<td class="photo"><a href="'.getNormalImage($file).'">
<img src="'.$file.'" alt="'.$file.'"/></a></td>';
}
}
}
}
}
}
?>
