PHP Reading Request Data Handling file upload errors
Example
The $_FILES["FILE_NAME"]['error'] (where "FILE_NAME" is the value of the name attribute of the file input, present in your form) might contain one of the following values:
UPLOAD_ERR_OK- There is no error, the file uploaded with success.UPLOAD_ERR_INI_SIZE- The uploaded file exceeds the upload_max_filesize directive inphp.ini.UPLOAD_ERR_PARTIAL- The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.UPLOAD_ERR_NO_FILE- No file was uploaded.UPLOAD_ERR_NO_TMP_DIR- Missing a temporary folder. (From PHP 5.0.3).UPLOAD_ERR_CANT_WRITE- Failed to write file to disk. (From PHP 5.1.0).UPLOAD_ERR_EXTENSION- A PHP extension stopped the file upload. (From PHP 5.2.0).
An basic way to check for the errors, is as follows:
<?php
$fileError = $_FILES["FILE_NAME"]["error"]; // where FILE_NAME is the name attribute of the file input in your form
switch($fileError) {
case UPLOAD_ERR_INI_SIZE:
// Exceeds max size in php.ini
break;
case UPLOAD_ERR_PARTIAL:
// Exceeds max size in html form
break;
case UPLOAD_ERR_NO_FILE:
// No file was uploaded
break;
case UPLOAD_ERR_NO_TMP_DIR:
// No /tmp dir to write to
break;
case UPLOAD_ERR_CANT_WRITE:
// Error writing to disk
break;
default:
// No error was faced! Phew!
break;
}
