دوستان من یه فرم آپلود فایل دارم می خوام براش محدودیت زارم مثل اینکه اگه حجمش از 3MB بیشتر بود پیغام بده و فقط فرمت هایی که من می گم آپلود بشه در غیر این صورت پیغام خطا بده.
حجم فایل = 3MB در غیر این صورت پیغام خطا و آپلود نشود.
نوع فایل مشخص = zip - rar - pdf - jpg - bmp - gif - doc در غیر این صورت خطا و فایل آپلود نشود.
با سلام

با سلام، این کد رو تست کنید. امیدوارم به درد بخوره:
if(isset($_FILES['photo'])) {
$photo = &$_FILES['photo'];
$ext = substr($photo['name'], -3);
$exts = array('doc', 'gif', 'bmp', 'jpg', 'pdf', 'rar', 'zip');
if($photo['size'] > 3145728) {
echo 'Size error (must be < 3MB)<br/>'."\n";
}
elseif(in_array($ext, $exts)) {
move_uploaded_file($photo['tmp_name'], 'images/'.$photo['name']);
}
else {
echo 'Invalid file (only ';
foreach($exts as $ext) {
echo '".'.$ext.'" ';
}
echo 'extensions are allowed<br/>'."\n";
}
}
