If you’re developing a nice website like Facebook or Youtube where subscribers share images and videos, or you’re selling premium content like e-books online, you have to provide a way for users to upload content. In this tutorial, I will show you how to add file uploading capability to your web page like a pro.The W3C HTML Standard defines each designed to handle a specific type of data. For file uploading purposes, the HTML input element, aptly a tag named, has been provided. How does it work? Let’s dive straight into the tutorial to find out.The HTML5 File Input ElementThe file element is created using the input type=file as shown below. The first example creates a single file upload box whereas the second example creates a multi-file upload field. This web page completes our work on the client side.
Let’s now develop the server-side code. Handling File Uploads On The Server SideWhen the user clicks the “Upload Now” button, the browser will post the form data along with the file contents to the script mentioned in the action attribute ( uploadfiles.php) The script then collects the file and saves on the server. Create a folder named “uploads” on your web server at the same path level as the uploadfiles.php file. This is where we will save the uploaded files.
Now we have to add the following PHP code to handle the upload.First, we check if the form is posted and then check if the file is uploaded successfully. If you upload this php script to your website, you will be able to upload files through the form. Notes on setting up the web server for successful file uploadsThere are several configuration parameters that can affect the file upload. These configuration parameters have to be setup right for the file uploads to work fine.
The folder in which the files are saved should be writable by the script.This is obvious but might be overlooked. The folder must be writable by the script means the web server user (usually www-data ) should have write access to the folder. So setup the folder permissions right.
If you have shell access, the folder permissions can be updated using the ‘chmod’ command easily. If you don’t have shell access, or if you have a shared hosting account, updating the folder permissions can be a little tricky.See if your hosting control panel has this feature. The websever configurationThe web server would have a configuration setting that (1) allows/disallows file uploads (2) sets a limit on the size of the file upload.Here are the typical settings you have to check (for PHP). memorylimit.
