  1. hi, i try your script n i get error "Failed to write file to disk. Introduced in PHP 5.1.0."

    what should i do to fix that..??
    my folder cmod already set to 7777...

    thx,

    opick

  2. make sure error reporting is on which may provide further detail:
    error_reporting(E_ALL | E_STRICT);
    ini_set('display_errors', 1);

    also, check out
    http://us.php.net/manual/en/features.file-upload.common-pitfalls.php
    http://us.php.net/manual/en/features.file-upload.errors.php
    http://us.php.net/manual/en/features.file-upload.post-method.php

  3. UPLOAD_ERR_CANT_WRITE sometimes means ran out of disk space on the temporary upload location.

    check the available diskspace on /tmp

  4. If security is an issue, you must never reply on $_FILES['myfile']['type'] as this can be modified by a naughty person. Instead, use exif_imagetype($_FILES["myfile"]["tmp_name"]).
