How do you store information from a PHP webform into a MYSQL database? It’s rather simple but, if you’ve never created one before, it can be daunting. I’ve encountered a lot of poorly produced videos, whether video quality or voice, and overly complicated tutorials. The hope for this post is to help those who’ve encountered similar issues and hopefully make learning about PHP and MySQL easier.
I’ll be using a local server environment called MAMP—it works for MAC and Windows. Because I’m developing locally, and needing PHP, Apache, and a database, MAMP encompasses everything I need. It’s free and easy to use. First open MAMP or whatever LAMP software you choose. If your web host offers MySQL, it probably offers phpMyAdmin, which is a web interface to manage your database. If you have cPanel, phpMyAdmin is probably located there. Navigate to phpMyAdmin within “Tools”. You’ll need to create a new database called “tutorial”, since this is a tutorial. This will be a simple form to gather users’ name and email, so the table name will be called “person”. Remember, keep naming conventions consistent. You’ll find people creating uppercase or camel case, but traditionally most stick to lowercase. Once your table is setup, you’ll need to create four columns, as follows:
id INT(11) AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(60) NOT NULL,
email VARCHAR(60) NOT NULL,
Everything should be straightforward, except for “id”. It needs to be auto incremented so you know who submitted chronologically. Meaning, if John was the very first submission and David was the second, you would see John as number 1 and David as number 2. Also, don’t allow white spaces. You’ll want to use underscore for things like full_name. Set the length/value for “name” and “email” to 60. We’ll also have a timestamp, so you can see when a user submitted. I would highly advise adding this field no matter what because if you add it later, after there’s been submissions in the database, those submissions will automatically have the date when you added the new field.
The second and third portions, HTML and PHP, are rather self-explanatory. If not, I’ve added inline documentation to better explain. If you’re using MAMP, your files will need to be placed within MAMP’s htdocs folder.
