PHP: Upload File
Simple example that shows how to upload a file using PHP.
Both the form and the data processer are on the same page. Configure the upload path and the max file size as per your requirements.
code snippet:
<?php
// basic php file upload example
// http://php.snippetdb.com
if ($_POST['upload']){ //process uploaded file
$uploadDir = '/path/to/upload/directory/'; //file upload path
$uploadFile = $uploadDir . $_FILES['uploadfile']['name'];
echo "<pre>";
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $uploadFile) )
{
echo "File is valid, and was successfully uploaded. ";
echo "Here's some more debugging info:\n";
}
else
{
echo "ERROR! Here's some debugging info:\n";
echo "remember to check valid path, max filesize\n";
}
var_dump($_FILES);
echo "</pre>";
} else { //display upload form
?>
<form enctype="multipart/form-data" action="<?php echo $_SERVER['SCRIPT_NAME']?>" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1024000">
<br>
<input name="uploadfile" type="file">
<br>
<input name= "upload" type="submit" value="Upload File">
</form>
<?php
}
?>
notes:
PHP stores all the uploaded file information in the $_FILES autoglobal array.
$_FILES['userfile']['name']
The original name of the file on the client machine.
$_FILES['userfile']['type']
The mime type of the file, if the browser provided this information. An example would be "image/gif".
$_FILES['userfile']['size']
The size, in bytes, of the uploaded file.
$_FILES['userfile']['tmp_name']
The temporary filename of the file in which the uploaded file was stored on the server.
$_FILES['userfile']['error']
The error code associated with this file upload. ['error'] was added in PHP 4.2.0.
Files will by default be stored in the server's default temporary directory, unless another location has been given with the upload_tmp_dir directive in php.ini. Use move_uploaded_file() to store an uploaded file somewhere permanently.
