PHP image upload using POST

I am trying to make a simple image loader. I have searched for hours and I made sure to set the enctype and I also changed my php.ini to match what I want to do. The file and folder permissions are also correct. I tried the same code on another webserver and it works. I am running apache2 with php5 on raspberry pi .

HTML code

<form method="post" enctype="multipart/form-data" action="upload.php">
    <table>
        <tr><td><input type="file" name="uimage"></td></tr>
        <tr><td><input name="Submit" type="submit" value="Upload image"></td></tr>
    </table>    
</form>

PHP Code

var_dump($_FILES);

PHP code returns an empty array. var_dump($_POST);

works fine. On the other server both are running and the image upload is successful. I am assuming it is related to my server. I checked the php.ini and 000-default file in the allowed sites, but really can't figure out what is causing the problem.

This is what the error.log from apache2 says:

PHP note: Undefined index: uimage in /var/www/dmz/dotpic/upload.php on line 48, referent: http: //localhost/upload.php

Edit:

By "POST" in the title of the question, I mean the form method I am using. I am not trying to access the image using an array $_POST

. Sorry for this.

use $_FILES['uimage']

to access your file, $ _POST doesn't work for files. more details about this link: http://www.w3schools.com/php/php_file_upload.asp

You shouldn't use $_POST

to get the files, you must use $_FILES['uimage']

to get the downloaded file.



$_FILES['uimage']

is an array with some information about the size, the temporary name of the uploaded file, the results of the upload, and the file type of the uploaded file.

As mentioned above. You must use $ _FILES ['uimage'] and not $ _POST ['uimage']. Good luck. :)
