I`m very new in PHP and am trying to make a photo gallery.
I found a tutorial that helped me come this far, but gives me blank page.
This is my code:
<?php
// Open the actual directory
if ($handle = opendir(".")) {
// Read all file from the actual directory
while ($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 displayPhotos(){
global $columns;
generateThumbnails();
$act = 0;
// Open the actual directory
if ($handle = opendir(".")) {
// 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>';
}
}
}
}
}
}
?>

<body>
<table align="center"><tr>
<?php displayPhotos(); ?>
</table>
</body>
</html>
My photos are in the same folder as this file.
Did some research online and got told that is_file need the path to the file, if this is so how must i change the code.
Help is appriciated!
