Hi all,
I have the following gallery code example found at
http://www.sitepoint.com/article/php-gallery-system-minutes
oblem with an image gallery code
<?php
include("config.inc.php");
// initialization
$result_final = "";
$counter = 0;
$images_dir = "photos";
// List of our known photo types
$known_photo_types = array(
'image/pjpeg' => 'jpg',
'image/jpeg' => 'jpg',
'image/gif' => 'gif',
'image/bmp' => 'bmp',
'image/x-png' => 'png'
);
// GD Function List
$gd_function_suffix = array(
'image/pjpeg' => 'JPEG',
'image/jpeg' => 'JPEG',
'image/gif' => 'GIF',
'image/bmp' => 'WBMP',
'image/x-png' => 'PNG'
);
// Fetch the photo array sent by preupload.php
$photos_uploaded = $_FILES['photo_filename'];
// Fetch the photo caption array
$photo_caption = $_POST['photo_caption'];
while( $counter <= count($photos_uploaded) )
{
if($photos_uploaded['size'][$counter] > 0)
{
if(!array_key_exists($photos_uploaded['type'][$counter], $known_photo_types))
{
$result_final .= "File ".($counter+1)." is not a photo<br />";
}
else
{
mysql_query( "INSERT INTO gallery_photos(`photo_filename`, `photo_caption`, `photo_category`) VALUES('0', '".addslashes($photo_caption[$counter])."', '".addslashes($_POST['category'])."')" );
$new_id = mysql_insert_id();
echo "New id=".$new_id;
echo "<br>";
$filetype = $photos_uploaded['type'][$counter];
$extention = $known_photo_types[$filetype];
$filename = $new_id.".".$extention;
mysql_query( "UPDATE gallery_photos SET photo_filename='".addslashes($filename)."' WHERE photo_id='".addslashes($new_id)."'" );
// Store the orignal file
copy($photos_uploaded['tmp_name'][$counter], $images_dir."/".$filename);
// Let's get the Thumbnail size
$size = GetImageSize( $images_dir."/".$filename );
echo "Width=".$size[0];
echo "<br>";
echo "Length=".$size[1];
echo "<br>";
if($size[0] > $size[1])
{
$thumbnail_width = 100;
$thumbnail_height = (int)(100 * $size[1] / $size[0]);
}
else
{
$thumbnail_width = (int)(100 * $size[0] / $size[1]);
$thumbnail_height = 100;
}
echo "destination dir=".$images_dir."/".$filename ;
echo "<br>";
// Build Thumbnail with GD 1.x.x, you can use the other described methods too
$function_suffix = $gd_function_suffix[$filetype];
$function_to_read = "ImageCreateFrom".$function_suffix;
$function_to_write = "Image".$function_suffix;
// Read the source file
//$source_handle = $function_to_read ( $images_dir."/".$filename );
$source_handle = $function_to_read ( "photos/".$filename );
echo "Function To read =".$source_handle;
echo "<br>";
if($source_handle)
{
echo "Insdide Source Handle=";
echo "<br>";
// Let's create an blank image for the thumbnail
$destination_handle = ImageCreate ( $thumbnail_width, $thumbnail_height );
// Now we resize it
ImageCopyResized( $destination_handle, $source_handle, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $size[0], $size[1] );
}
// Let's save the thumbnail
$res = $function_to_write( $destination_handle, $images_dir."/tb_".$filename );
echo "Function To_write Handle=".$res;
echo "<br>";
ImageDestroy($destination_handle );
//
$result_final .= "<img src=".$images_dir. "/tb_".$filename." /> File ".($counter+1)." Added<br />";
}
}
$counter++;
}
// Print Result
echo <<<__HTML_END
<html>
<head>
<title>Photos uploaded</title>
</head>
<body>
$result_final
</body>
</html>
__HTML_END;
?>
Everything works fine if I run the code locally but when I run the code on a remote server, no image is displayed in the browser.
I can see that files are loaded into "photos" directory on the server side but no image in the browser.
What is going wrong.
any suggestions.
thanks
regards
