upload + resize

[Baly23]

ho guardato anche la pillola al riguardo, ma con le classi e le funzioni, nn c'ho capito proprio niente :master:

cmq avevo intenzione di realizzare appunto uno script che mi uppi le immagini, me li resizza a 800x600 e mi crea le miniature...

questo è il form:

<?
echo '
<form action="./gallery.php?action=upload" method="post" enctype="multipart/form-data">

File:

<input name="file" type="file">

<input name="invio" type="submit" value="Invia">

</form>
';

?>

questo è lo script:

<?
$DB = mysql_query("SELECT * FROM g_vtuning ORDER BY id DESC");
$row = mysql_fetch_assoc($DB);
$lastid1 = ($row['id'] + 1);
$upload_dir = "./images/gallery/";

if(isset($_POST['invio'])){
           $photo = $_FILES['file'];
       $photo_name = $lastid1.'.jpg';
       $th_name = $lastid1.'.th.jpg';
           $photo_tmp = $new_file['tmp_name'];
           $photo_size = $new_file['size'];
           
list($width, $height) = getimagesize($photo);
if($width>$height){
$photo_width = 800;
$photo_height = 600;
$thumbnails_width = 100;
$thumbnails_height = 75;
}
if($width<$height){
$photo_width = 600;
$photo_height = 800;
$thumbnails_width = 75;
$thumbnails_height = 100;
}

$new_photo = imagecreatetruecolor($newwidth, $newheight);
$new_th = imagecreatetruecolor($thumbnails_width, $thumbnails_height);
$source = imagecreatefromjpeg($photo);

$def_photo = imagecopyresized($new_photo, $source, 0, 0, 0, 0, $photo_width, $photo_height, $width, $height);
$def_th = imagecopyresized($new_th, $source, 0, 0, 0, 0, $thumbnails_width, $thumbnails_height, $width, $height);

imagejpeg($def_photo);
imagejpeg($def_th);

    move_uploaded_file($def_photo,$upload_dir.$photo_name);
    move_uploaded_file($def_th,$upload_dir.$th_name);
    }
?>

da premettere che nn da parse error...

$fullsize=imagecreatefromjpeg("images/gallery/$uploadedfile_name");
$fullsize_height=imagesy($fullsize);
$fullsize_width=imagesx($fullsize);

if($fullsize_width>$fullsize_height){
$thumb_width=120;
$thumb_height=90;
if($fullsize_width>799){
$photo_width=800;
$photo_height=600;
}
if($fullsize_width<799){
$photo_width=640;
$photo_height=480;
}
}

else if($fullsize_width<$fullsize_height){
$thumb_width=90;
$thumb_height=120;
if($fullsize_width>599){
$photo_width=600;
$photo_height=800;
}
if($fullsize_width<599){
$photo_width=480;
$photo_height=640;
}
}

$thumb=imagecreatetruecolor($thumb_width,$thumb_height);
$photo=imagecreatetruecolor($photo_width,$photo_height);
imagecopyresampled($thumb,$fullsize,0,0,0,0,$thumb_width,$thumb_height,$fullsize_width,$fullsize_height);
imagecopyresampled($photo,$fullsize,0,0,0,0,$photo_width,$photo_height,$fullsize_width,$fullsize_height);
 
imagejpeg($thumb,"images/gallery/$lastid1.th.jpg");
imagejpeg($photo,"images/gallery/$lastid1.jpg");
imagedestroy($fullsize);
imagedestroy($thumb);
imagedestroy($photo);
imagedestroy($uploadedfile);
imagedestroy($uploadedfile_name);
