The frontend is handled by the HTML form that uses the form input type file. On the backend, the file upload library processes the submitted input from the form and writes it to the upload directory. Let's begin with the input form. If the result is true then the error returned by the upload library is displayed to the user.

This is important for security reasons. The allowed types ensures that only images are uploaded and other file types such as php cant be uploaded because they have the potential to compromise the server. In our example, the maximum file that can be uploaded is 2,kb close to 2MB. If the user tries to upload a file larger than 2,kb, then the image will fail to upload and the library will return an error message.
That is it for the controller. Let's now create the directory where our images will be uploaded to. Create a new directory "images" in the root directory of your application Finally, we will ad two routes to our routes. Click on an upload image button You will get the following results assuming everything goes well Click on View My Image! Link You should be able to see the image that you uploaded. The results will be similar to the following Notice uploaded image name is displayed in the URL.
