PHP upload obrazec včasih dela, včasih ne?

Zdravo

Spisat skušam obrazec za nalaganje datotek, ki včasih dela, včasih pa ne. Kako je to sploh možno?

Lahko nekdo prosim pregleda kodo in prosim pove, kaj delam narobe? Delam pa to kr preko Wampa na svojem računalniku.

<?php

if(isset($_POST["upload"])) {

	// VARIABLES
	// default values
	$error_msg = "";
	$error 	   = false;

	// SUPPORTED FILE EXTENSIONS
	// users can upload only MP3 files 
	$allowed_ext = array("audio/mp3");

	if(in_array($_FILES["song"]["type"], $allowed_ext)) {
		$error = false;
	}
	else {
		$error = true;
		$error_msg .= "<p style='color: red'>You can upload only files with .mp3 extension!</p>";
	}
	
	// SUPPORTED FILE SIZE
	// max file upload size is 12 MB
	if($_FILES["song"]["size"] <= 12582912) {
		$error = false;
	}
	else {
		$error = true;
		$error_msg .= "<p style='color: red'>Maximum upload file size is 12 MB!</p>";
	}
	
	if($error) echo $error_msg;

}

?>

V apache error logu so naslednje napake:

Ta pogojni stavek sem zamenjal, tnx

Ne razumem, zakaj skripta spusti skozi druge datoteke in jih vseeno naloži, če sem pa omejil samo na MP3 datoteke?

TRENUTNA KODA

<?php

if(isset($_POST["upload"])) {

	// VARIABLES
	// default values
	$upload_dir = "upload/";
	$error_msg  = "";
	$error 	    = false;

	// SUPPORTED FILE EXTENSIONS
	// users can upload only MP3 and AAC (m4a) files 
	$allowed_ext = array("audio/mp3");

	if(!in_array($_FILES["song"]["type"], $allowed_ext)) {
		$error = true;
		$error_msg .= "<p style='color: red'>You can upload only files with .mp3 and .m4a extensions!</p>";
	}
	
	// SUPPORTED FILE SIZE
	// max file upload size is 12 MB
	if($_FILES["song"]["size"] > 12582912) {
		$error = true;
		$error_msg .= "<p style='color: red'>Maximum upload file size is 12 MB!</p>";
	}
	
	// FILE ALREADY EXIST
	if(file_exists($upload_dir.$_FILES["song"]["name"])) {
		$error = true;
		$error_msg .= "<p style='color: red'>File already exist!</p>";
	}
	
	// UPLOAD FILES
	// if there aren't any errors, user can upload a file
	if($error) echo $error_msg;
	else {
	
		move_uploaded_file($_FILES["song"]["tmp_name"], $upload_dir.$_FILES["song"]["name"]);
		echo "SUCCESS!";
	
	}

}

?>

V php.ini mam pa nastavljen "post_max_size" in "upload_max_filesize" na 30M, medtem ko v sami skripti dovoljujem samo upload datotek z maximalno velikostjo 12M.

Še vedno mi ni jasno, kaj delam narobe. Please help me

Hvala in lp,
Housy

Če naložim npr. Word datoteko z .docx končnico in izvedem funkcijo var_dump, dobim ven naslednje podatke:

array (size=1)
'song' =>
array (size=5)
'name' => string 'BLABLA.docx' (length=11)
'type' => string 'application/vnd.openxmlformats-officedocument.wordprocessingml.document' (length=71)
'tmp_name' => string 'C:\wamp\tmp\phpA9DE.tmp' (length=23)
'error' => int 0
'size' => int 13947

Kar se pa tiče arraya[0], pa ne pride v poštev, saj imam input značko takole naštimano:

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

Drugač pa mi je zdaj spet skripta normalno delovala, vsi pogojni stavki so bili upoštevani oz. so se izvedli ustrezno. Nimam pojma, kaj se to dogaja.

Je mogoče WAMP kaj kriv?

usoban je 27. jul 2013 ob 19:49 izjavil:

[Sat Jul 27 12:52:05.137446 2013] [:error] [pid 2796:tid 1544] [client 127.0.0.1:51024] PHP Notice: Array to string conversion in C:\\wamp\\www\\sound\\index.php on line 15, referer: http://localhost/sound/index.php

Zdaj v 15. vrstici (in_array) so argumenti pravilno podani, tako da zna preveri z

var_dump($_FILES)

da nimas slucajno arraya, ker potlej moras do informacij o datoteki dostopat se z indeksom

$_FILES['song']['type'][0]
