PHP $_FILES multiple file uploading problem

Question

I have a little problem with uploading multiple files in PHP ,

i have this html form:

<form method="post" action="upload.php" enctype="multipart/form-data">
    <input type="file" name="myfile[]"  />
    <input type="submit" />
</form>

and this is the upload.php :

<?php print_r( $_FILES ); ?> 

when i'm sending a file it show me this:

 Array
(
[myfile] => Array
    (
        [name] => Array
            (
                [0] => Krw_Qe4QKmI.mp3
            )

        [type] => Array
            (
                [0] => 
            )

        [tmp_name] => Array
            (
                [0] => 
            )

        [error] => Array
            (
                [0] => 1
            )

        [size] => Array
            (
                [0] => 0
            )

    )

 )

so far so good.

the problem starts when i upgrade my form to this one :

<form method="post" action="upload.php" enctype="multipart/form-data">
    <input type="file" name="myfile[]"  />
    <input type="file" name="myfile[]"  />
    <input type="submit" />
</form>

now , when i send 2 files , it show me this :

Array
(
)

so , what's the problem here? thank you , Mor.

Solution 1

A lot of suggestions here. I'll give it a go. This is based on @Pekka 's comment.

I see you're testing with mp3s, which probably exceed PHP upload limit. This is because in your first example, you actually have an upload error code 1: The uploaded file exceeds the upload_max_filesize directive in php.ini.. So even your fist upload didn't work. A successful upload always has 0 as the error code.

Modify you php.ini with upload_max_filesize = 10M (or 20M, or 300M; careful about that M - which means megabytes - as omitted, brings alot of headache.

I suggest testing with smaller files, as I see you have a limit of 2M for uploading.

Solution 2

I would bet that you exceeded post_max_size and PHP just ignored the uploaded files.

It's 8MB by default. If you try to upload one 5MB file everything will work. If you try to upload 2 5MB files, it exceeeds 8MB and PHP ignores posted data.

Try increasing the value of post_max_size in your php.ini.

Solution 3

Check your max_file_uploads setting -- is it more than 1?

echo ini_get('max_file_uploads');

i did run this command but nothing came up , i also checked in the ini file it self it does not have such a thing

[Arnaud Le Blanc]

enable log_errors and look at your server's error_log

im checking now , so far i can see if i upload 2 small files it works but with bigger files it wont

[homerun]

i dont have the max_file_uploads part on my ini file , can you tell me which system you work with and download link to you're ini file?

[Pekka]

@Mor you need to modify your own php.ini, it's no good downloading somebody else's

[tttony]

that's weird, you can copy & paste the code in you php.ini file and this is the content of the php.ini recommend I have php 5.2.17

i run my code on WAMP 2 32 bit , this is what's on my ini ;;;;;;;;;;;;;;;; ; File Uploads ; ;;;;;;;;;;;;;;;; ; Whether to allow HTTP file uploads. ; php.net/file-uploads file_uploads = On ; Temporary directory for HTTP uploaded files (will use system default if not ; specified). ; php.net/upload-tmp-dir upload_tmp_dir = "c:/wamp/tmp" ; Maximum allowed size for uploaded files. ; php.net/upload-max-filesize upload_max_filesize = 2M

Actually, you can upload multiple files having the same input name, just like OP used: name[].
