<form method="post" action="reg.php" enctype="multipart/form-data">
    <table width="100%" class="table4" cellpadding="0" cellspacing="0">

In reg.php

Please help!

My file is a 20kb png file and from phpinfo():

file_uploads    On  On

max_file_uploads    20  20

post_max_size   10M 10M

upload_max_filesize 10M 10M

Answer 1

The only case that I could think of where the keys are not being found are:

• You are unsetting the key for some odd reason.
• file_uploads is disabled.

Most probably the uploaded images exceed the maximum size defined in the server’s configuration. You can invoke phpinfo() to check your current limits.

If you want to change them, just modify the following properties on php.ini as needed:

; Maximum file size of post data that PHP will accept.
post_max_size = 20M

; Maximum allowed file size for uploaded files.
upload_max_filesize = 20M

Or use php_value within .htaccess:

php_value upload_max_filesize 100M
php_value post_max_size 100M
