I did the watermark images tutorial and it is working good. I implement the watermark function in an upload image tutorial, chanced a little bit, checked if it is still working and no, it isn't working any more and I can't get it let working again.
Can anybody tell me why it is not working?
This is the upload image page;
<?php
include 'init.php';
if (!logged_in()) {
header('Location: administratie.php');
exit();
}
include 'template/header.php';
?>
<h3>Upload foto</h3>
<?php
if (isset($_FILES['image'], $_POST['album_id'])) {
$image_name = $_FILES['image'] ['name'];
$image_size = $_FILES['image'] ['size'];
$image_temp = $_FILES['image'] ['tmp_name'];
$allowed_ext = array('jpg', 'jpeg', 'png', 'gif');
$image_ext = strtolower(end(explode('.',$image_name)));
$album_id = $_POST['album_id'];
$errors = array();
if (empty($image_name) || empty($album_id)) {
$errors[] = 'Niet alles is ingevuld';
} else {
if (in_array($image_ext, $allowed_ext) === false) {
$errors[] = 'Bestandsnaam is niet toegestaan.';
}
if ($image_size > 2097152) {
$errors[] = 'Je kan maximaal 2mb uploaden.';
}
if (album_check($album_id) === false) {
$errors[] = 'Er kan niet naar dit album worden geupload.';
}
}
if (!empty($errors)) {
foreach ($errors as $error) {
echo $error, '<br />';
}
} else {
upload_image($image_temp, $image_ext, $album_id);
header('Location: view_album.php?album_id='.$album_id);
exit();
}
//This is the watermark_image part
$image_output = 'uploads/' . md5(microtime(true)).'.png';
watermark_image($image_temp, $image_output);
}
$albums = get_albums();
if (empty($albums)) {
echo '<p>Je hebt nog geen albums. <a href="create_album.php">Maak een album.</a></p>';
} else {
?>
<form action="" method="post" enctype="multipart/form-data">
<p>Kies een foto:<br /><input type="file" name="image" /></p>
<p>
Kies een album:<br />
<select name="album_id">
<?php
foreach ($albums as $album) {
echo '<option value="', $album['id'], '">', $album['name'], '</option>';
}
?>
</select>
</p>
<p><input type="submit" value="Upload" /></p>
</form>
<?php
}
include 'template/footer.php';
?>
The function is;
<?php
function upload_image($image_temp, $image_ext, $album_id) {
$album_id = (int)$album_id;
mysql_query("INSERT INTO `images` VALUES ('', '".$_SESSION['user_id']."', '$album_id', UNIX_TIMESTAMP(), '$image_ext')");
$image_id = mysql_insert_id();
$image_file = $image_id.'.'.$image_ext;
move_uploaded_file($image_temp, 'uploads/'.$album_id.'/'.$image_file);
create_thumb('uploads/'.$album_id.'/', $image_file, 'uploads/thumbs/'.$album_id.'/');
}
function get_images($album_id) {
$album_id = (int)$album_id;
$images = array();
$image_query = mysql_query("SELECT `image_id`, `album_id`, `timestamp`, `ext` FROM `images` WHERE `album_id`=$album_id AND `user_id`=".$_SESSION['user_id']);
while ($images_row = mysql_fetch_assoc($image_query)) {
$images[] = array(
'id' => $images_row['image_id'],
'album' => $images_row['album_id'],
'timestamp' => $images_row['timestamp'],
'ext' => $images_row['ext']
);
}
return $images;
}
function image_check($image_id) {
$image_id = (int)$image_id;
$query = mysql_query("SELECT COUNT(`image_id`) FROM `images` WHERE `image_id`=$image_id AND `user_id`=".$_SESSION['user_id']);
return (mysql_result($query, 0) == 0) ? false : true;
}
//The watermark_image part
function watermark_image($image, $output) {
$info = getimagesize($image);
switch ($info['mime']){
case 'image/jpeg';
$main = imagecreatefromjpeg($image);
break;
case 'image/png';
$main = imagecreatefrompng($image);
break;
case 'image/gif';
$main = imagecreatefromgif($image);
break;
default:
return false;
}
imagealphablending($main, true);
$overlay = imagecreatefrompng('watermark.png');
imagecopy($main, $overlay, 5, 5, 0, 0, imagesx($overlay), imagesy($overlay));
imagepng($main, $output);
}
function delete_image($image_id) {
$image_id = (int)$image_id;
$image_query = mysql_query("SELECT `album_id`, `ext` FROM `images` WHERE `image_id`=$image_id AND `user_id`=".$_SESSION['user_id']);
$image_result = mysql_fetch_assoc($image_query);
$album_id = $image_result['album_id'];
$image_ext = $image_result['ext'];
unlink('uploads/'.$album_id.'/'.$image_id.'.'.$image_ext);
unlink('uploads/thumbs/'.$album_id.'/'.$image_id.'.'.$image_ext);
mysql_query("DELETE FROM `images` WHERE `image_id`=$image_id AND `user_id`=".$_SESSION['user_id']);
}
?>
Thanks in advance.
