Question

I am new to php. I have searched for a solution to this problem for over 1 hour but could not find an answer.

Example situation: Check uploaded file extension & size and echo out errors for each failure (if any)(stopping at first failure).

Code so far:

$allowedfiletypes = array("image/jpg","image/jpeg","image/png");
if((!in_array($filetype, $allowedfiletypes))) {
    echo "Error, disallowed file type.";
} elseif($filesize > 1048576) {
    echo 'Filesize too large';
} else {
    move_uploaded_file($filetmpname, $uploaddir."/".$filename);
    echo 'The file has the following properties:'." ".$filename.", ".$filesize."kb, ".$filetype.".".'<br><br>';
    echo ' The file is stored in'.$uploaddir.$filename;
}

But this does not work if the file size is over the specified limit.

How can i do if() {echo 'error1';} || if {echo 'error2'.} else {}?

Answer 1

Why not use flags?

$error1 = 1;
$error2 = 1;

if($error1 && $error2) { ... }

Or use an error counter and die if it reaches a particular count.
