Hallo 我想上传一个文件。脚本应该拍摄图像，调整大小并上传。 但似乎有任何未知的我上传错误。文件无故上传丢失
下面的代码
define ("MAX_SIZE","2000"); // maximum size for uploaded images
define ("WIDTH","107"); // width of thumbnail
define ("HEIGHT","107"); // alternative height of thumbnail (portrait 107x80)
define ("WIDTH2","600"); // width of (compressed) photo
define ("HEIGHT2","600"); // alternative height of (compressed) photo (portrait 600x450)
if (isset($_POST['Submit'])) {
// iterate thorugh all upload fields
foreach ($_FILES as $key => $value) {
//read name of user-file
$image = $_FILES[$key]['name'];
// if it is not empty
if ($image) {
$filename = stripslashes($_FILES[$key]['name']); // get original name of file from clients machine
$extension = getExtension($filename); // get extension of file in lower case format
$extension = strtolower($extension);
// if extension not known, output error
// otherwise continue
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) {
echo '<div class="failure">Fehler bei Datei '. $_FILES[$key]['name'] .': Unbekannter Dateityp: Es können nur Dateien vom Typ .gif, .jpg oder .png hochgeladen werden.</div>';
} else {
// get size of image in bytes
// $_FILES[\'image\'][\'tmp_name\'] >> temporary filename of file in which the uploaded file was stored on server
$size = getimagesize($_FILES[$key]['tmp_name']);
$sizekb = filesize($_FILES[$key]['tmp_name']);
// if image size exceeds defined maximum size, output error
// otherwise continue
if ($sizekb > MAX_SIZE*1024) {
echo '<div class="failure">Fehler bei Datei '. $_FILES[$key]['name'] .': Die Datei konnte nicht hochgeladen werden: die Dateigröße überschreitet das Limit von 2MB.</div>';
} else {
$rand = md5(rand() * time()); // create random file name
$image_name = $rand.'.'.$extension; // unique name (random number)
// new name contains full path of storage location (images folder)
$consname = "photos/".$image_name; // path to big image
$consname2 = "photos/thumbs/".$image_name; // path to thumbnail
$copied = copy($_FILES[$key]['tmp_name'], $consname);
$copied = copy($_FILES[$key]['tmp_name'], $consname2);
$sql="INSERT INTO photos (galery_id, photo, thumb) VALUES (". $id .", '$consname', '$consname2')" or die(mysql_error());
$query = mysql_query($sql) or die(mysql_error());
// if image hasnt been uploaded successfully, output error
// otherwise continue
if (!$copied) {
echo '<div class="failure">Fehler bei Datei '. $_FILES[$key]['name'] .': Die Datei konnte nicht hochgeladen werden.</div>';
} else {
$thumb_name = $consname2; // path for thumbnail for creation & storage
// call to function: create thumbnail
// parameters: image name, thumbnail name, specified width and height
$thumb = make_thumb($consname,$thumb_name,WIDTH,HEIGHT);
$thumb = make_thumb($consname,$consname,WIDTH2,HEIGHT2);
}
}
}
}
}
// current image could be uploaded successfully
echo '<div class="success">'. $success .' Foto(s) erfolgreich hochgeladen!</div>';
showForm(); // call to function: create upload form
}
