Both PHP and MySQL are open-source relational database management systems. PHP is a server-side scripting computer language, and MySQL is an open-source relational database management system. When used in conjunction with one another, these two frameworks are possible to produce extremely original solutions, such as the generation of a login form.
This guide will walk you through the process of creating a straightforward login system using PHP and MySQL.
Let’s have a look at the requirements that need to be met in order to develop a login form before we get started with the PHP-related components of the language.
A working familiarity with HTML, CSS, PHP, and MySQL
Visual Studio, developed by Microsoft (For writing the code)
Step 1- We need to create a HTML PHP Login Form
Follow the procedures that are outlined below in order to construct a login form:
Launch the Microsoft Visual Studio on your computer -> Make a new file and save it under the name of an SL file.
Now, on a new page, write the code that is described in the upcoming example.
The HTML software will produce a webpage form that, when filled out, will enable users to log in to their accounts on their own.
The code is made up of different HTML elements.
These are the fundamental components:
The header of the document is shown by the element in question. The label can only be in text format, and the text will be displayed in the tab of the browser if it is used.
It creates a link between the document currently being worked on and an external resource.
This element defines the user input that is included into the production of an HTML document.
It presents the user with a single-line input area.
It defines a label for multiple form elements. It mostly highlights the radio button or checkbox.
Step 2: Draft a CSS Code for Website Design
The CSS sheet is the following element. The current task is to create a cascading style sheet, often known as a CSS file, with the intention of improving the appearance of the website.
The following code should be inserted into the.css file:
Save the file name as “Style.css” in Microsoft Visual Studio.
After the user has entered the input values, they will be compared to the credentials that have been stored in the database. When the user reaches this point, they will be redirected to the following screen to confirm their username and password. Your login attempt will be denied if you do not comply with these instructions.
Now, the credentials must be added to the database in order to log in.
Step 3: Using MySQL, create a table for the database.
When you create a database, you are essentially assembling a structure that resembles the following:
Now, start your SQL Xampp server and select the administrator option. This link will take you to the phpMyAdmin website. Here, let us enter your username and password to log in.
Now, create a new database on MyPHPAdmin by clicking “New” on the left side of the page..
Next, give the database a name where it says “Create database.”
Then, you will be brought to the page where a new table will be created. Now, input the table’s desired name.
After that, you will be able to choose the desired type number for the ‘Fields’ text box.
Note that the fields match to the columns; for instance, the login, password, and address are included in some of the fields. Enter the number “4” into the available text box. If necessary, you can also increase the quantity in accordance with the demand.
In the text area, choose these options.
Select an option from the drop-down menu to generate a primary key for the ID field, then click the save button.
Note: If you are using a later version of phpMyAdmin and you receive error number #1067, change the TimeStamp option in the Default drop-down list to None.
After saving, you will be directed to a screen displaying the structure.
Step 4: this involves establishing a connection to a MySQL database.
Following the establishment of a database with PHPMyAdmin, the next step is to create code with Visual Studio.
To create a new file, use Microsoft Visual Code and save it with the name “DB connection.”
When you examine the code below, you will notice that there is a mysqli connect function ( ). Obviously, it serves the same purpose, given its name. It creates a link between the newly created form and the database.
This sample utilizes an if statement to determine whether or not the code is operating properly. Whether or not the database was located, the relevant message is generated.
Execute the following SQL query within your MySQL database to create the user table.
Step 5 – Create a Logout Session
This section will enable you to create a “logout.php” file. When the user selects the logout option, the snippet of the code mentioned below will redirect the user back to the login page automatically.
Step 6 – Create a Code for the Home Page
Next, the code for the home page is given below:
The PHP Login Form lesson has reached its conclusion. You learnt how to develop a PHP Login form, a CSS sheet for the website, a database, and Visual Studio code for the Database connection.
