Разъяснение сообщений об ошибках

Начиная с PHP 4.2.0, PHP возвращает код ошибки наряду с другими атрибутами принятого файла. Он расположен в массиве, создаваемом PHP при загрузке файла, и может быть получен при обращении по ключу ['error']. Говоря другими словами, код ошибки можно найти в переменной $_FILES['userfile']['error'].

UPLOAD_ERR_OK: Значение: 0; Ошибок не возникало, файл был успешно загружен на сервер.
UPLOAD_ERR_INI_SIZE: Значение: 1; Размер принятого файла превысил максимально допустимый размер, который задан директивой upload_max_filesize конфигурационного файла php.ini.
UPLOAD_ERR_FORM_SIZE: Значение: 2; Размер загружаемого файла превысил значение MAX_FILE_SIZE, указанное в HTML-форме.
UPLOAD_ERR_PARTIAL: Значение: 3; Загружаемый файл был получен только частично.
UPLOAD_ERR_NO_FILE: Значение: 4; Файл не был загружен.

Замечание: Константы были добавлены в PHP 4.3.0.

In response to Hans:  The problem with your switch statement is that it never allows for no errors, i.e. the UPLOAD_ERR_OK val.  So to still allow room for further errors, yet notice a no-error case, this needs to be addressed:



<?php

switch ($filearray["error"]) {

   case UPLOAD_ERR_OK:

       break;

   case UPLOAD_ERR_INI_SIZE:

       throw new Exception("The uploaded file exceeds the upload_max_filesize directive (".ini_get("upload_max_filesize").") in php.ini.");

       break;

   case UPLOAD_ERR_FORM_SIZE:

       throw new Exception("The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.");

       break;

   case UPLOAD_ERR_PARTIAL:

       throw new Exception("The uploaded file was only partially uploaded.");

       break;

   case UPLOAD_ERR_NO_FILE:

       throw new Exception("No file was uploaded.");

       break;

   case UPLOAD_ERR_NO_TMP_DIR:

       throw new Exception("Missing a temporary folder.");

       break;

   case UPLOAD_ERR_CANT_WRITE:

       throw new Exception("Failed to write file to disk");

       break;

   default:

       throw new Exception("Unknown File Error");

}

?>

Thank you stephen, that was very helpful ;-)



So, to repeat it for all, check your php.ini, 



post_max_size 



should be bigger than 



upload_max_filesize



, otherwise you will not be able to report the correct error in case of a too big upload ! Also check the max-execution-time (upload-time could be added to execution-time).

if post is greater thanpost_max_size set in php.ini



$_FILES and $_POST will return empty

or perhaps this:

<?php

switch ($filearray["error"]) {

    case UPLOAD_ERR_INI_SIZE:

        throw new Exception("The uploaded file exceeds the upload_max_filesize directive (".ini_get("upload_max_filesize").") in php.ini.");

    break;

    case UPLOAD_ERR_FORM_SIZE:

        throw new Exception("The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.");

    break;

    case UPLOAD_ERR_PARTIAL:

        throw new Exception("The uploaded file was only partially uploaded.");

    break;

    case UPLOAD_ERR_NO_FILE:

        throw new Exception("No file was uploaded.");

    break;

    case UPLOAD_ERR_NO_TMP_DIR:

        throw new Exception("Missing a temporary folder.");

    default:

        throw new Exception("An unknown file upload error occured");

}

?>

This is probably useful to someone.

<?

array(

        0=>"There is no error, the file uploaded with success", 

        1=>"The uploaded file exceeds the upload_max_filesize directive in php.ini", 

        2=>"The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form"

        3=>"The uploaded file was only partially uploaded",

        4=>"No file was uploaded",

        6=>"Missing a temporary folder" 

);

?>

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

}
