Q & A

What is the purpose of this tutorial?

The tutorial aims to teach how to upload files or images to a web interface and store them in a database, covering both the backend and frontend processes.

What needs to be added to the database to accommodate file uploads?

A new column named 'foto' (for photos) is added to the database table to store the file names of the uploaded images or documents.

What function is used for uploading files in the backend?

The function 'multipart/form-data' is used to handle file uploads, allowing both images and documents to be uploaded correctly.

How are uploaded files stored temporarily before being saved in the database?

Uploaded files are initially stored in a temporary location using the 'tmp_name' variable before being moved to a designated folder.

What is the purpose of the 'move_uploaded_file' function?

The 'move_uploaded_file' function is used to transfer the uploaded file from its temporary location to a permanent folder on the server, typically within a 'gambar' (image) folder.

What happens if a user does not upload a file?

If no file is uploaded, the script performs a validation check and shows an error message, ensuring that data is not saved in the database without a file.

How is the image displayed on the web page after uploading?

After the file is uploaded and stored, the image is displayed on the webpage by referencing its path in the 'gambar' folder and using the 'img' HTML tag to show it.

How does the system handle missing images in the database?

If no image is available for a record in the database, a default image (e.g., 'image.png') is displayed instead.

What is the significance of the 'multipart/form-data' enctype in the form?

The 'multipart/form-data' enctype is essential for handling file uploads in HTML forms, ensuring that files can be transmitted correctly alongside other form data.

What steps are taken to ensure a smooth user experience during the file upload process?

The tutorial ensures a smooth user experience by validating the uploaded file, providing feedback if the file is missing, and displaying the uploaded image in a consistent format.
