Very Simple Add, Edit, Delete, View (CRUD) in PHP & MySQL [Beginner Tutorial]
In this article, I will be presenting simple PHP & MySQL code to add, edit, delete and view data. This kind of system is also referred to CRUD (Create, Read, Update, Delete).
Here is a step-by-step guide on creating a CRUD system using PHP & MySQL:
First of all, we will create a new MySQL database. Let us name the database as ‘test‘.
Then, we will create a new table in database ‘test’. Let us name the table as ‘users‘.
Now, we will create a config.php file which contains database connection code. This code connects to the MySQL database. This file is included in all PHP pages where database connection is necessary.
dbConnection.php
In below code, the database host name is localhost where username=root and password=root . The database test has been selected.
To add data to the database, we need an html form.
Add Data
Home
Form action on add.php is addAction.php . It means that the submitted form data will go to addAction.php .
In addAction.php , we do a simple validation of checking if the entered name, email & age are empty or not. If they are all filled then the data will be inserted into database table.
addAction.php
Name field is empty.
"; > if (empty($age)) < echo "Age field is empty.
"; > if (empty($email)) < echo "Email field is empty.
"; > // Show link to the previous page echo "
Go Back"; > else < // If all the fields are filled (not empty) // Insert data into database $result = mysqli_query($mysqli, "INSERT INTO users (`name`, `age`, `email`) VALUES ('$name', '$age', '$email')"); // Display success message echo "Data added successfully!
"; echo "View Result"; > > ?>
