PHP file upload script

Firstly, to let visitors upload a file, you must create a form so enable users to choose a file:
In your html page, copy this:

<form enctype="multipart/form-data" action="uploader.php" method="POST">
Choose a file to upload: <input name="uploadedfile" type="file" />
<input type="submit" value="Upload File" />
</form>

This will enable the user to choose what file to upload and click "Upload File" button.

Choose a file to upload:

If you want to add a file size limit, add this line:

<form enctype="multipart/form-data" action="uploader.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile" type="file" />
<input type="submit" value="Upload File" />
</form>

Now create a file "upload.php" and a directory "uploads/"

In upload.php copy this php code:

$target_path = "uploads/" ;
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

This code will put all uploaded files to uploads/ directory.
$_FILES['uploadedfile']['name'] will get the file name, and add it to the string $target_path.
For example if someone upload a file: myfile.zip , it will save it to: uploads/myfile.zip .

To check if the file was uploaded successfully, add this script:

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {

echo "The file ". basename( $_FILES['uploadedfile']['name']).

" has been uploaded";

} else{

echo "There was an error uploading the file, please try again!";
}
