Error Messages Explained

Since PHP 4.2.0, PHP returns an appropriate error code along with the file array. The error code can be found in the error segment of the file array that is created during the file upload by PHP. In other words, the error might be found in $_FILES['userfile']['error'].

UPLOAD_ERR_OK: Value: 0; There is no error, the file uploaded with success.
UPLOAD_ERR_INI_SIZE: Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.
UPLOAD_ERR_FORM_SIZE: Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.
UPLOAD_ERR_PARTIAL: Value: 3; The uploaded file was only partially uploaded.
UPLOAD_ERR_NO_FILE: Value: 4; No file was uploaded.
UPLOAD_ERR_NO_TMP_DIR: Value: 6; Missing a temporary folder. Introduced in PHP 4.3.10 and PHP 5.0.3.

Note: These became PHP constants in PHP 4.3.0.

I noticed that on PHP-4.3.2 that $_FILES can also not be set if the file uploaded exceeds the limits set by upload-max-filesize in the php.ini, rather than setting error $_FILES["file"]["error"]

When $_FILES etc is empty like Dub spencer says in the note at the top and the error is not set, that might be because the form enctype isnt sat correctly. then nothing more than maybe a http server error happens.



enctype="multipart/form-data" works fine

Upload doesnt work, and no error?



actually, both $_FILES and $_REQUEST in the posted to script are empty?



just see, if  "post_max_size" is lower than the data you want to load.



in the apache error log, there will be an entry like "Invalid method in request". and in the access log, there will be two requests: one for the POST, and another that starts with all "----" and produces a 501.

In regards to the dud filename being sent, a very simple way to check for this is to check the file size as well as the file name.  For example, to check the file size simple use the size attribute in your file info array:



if($_FILES["file_id"]["size"]  == 0)

{

         ...PROCESS ERROR

}
