In this article, we will see how can we post form data to MYSQL in PHP using OOPS concept. We will write a separate function for form submission and then will include that in index.php
In the example below, we will take input from the user in a form and then we will submit that in the MYSQL database.
Index.php
<?php
include_once("function.php");
$insertdata=new DB_connection();
if(isset($_POST['submit']))
{
$name=$_POST['name'];
$email=$_POST['email'];
$contact=$_POST['contact'];
$gender=$_POST['gender'];
$education=$_POST['education'];
$sql=$insertdata->insertdData($name,$email,$contact,$gender,$education);
if($sql)
{
echo "<script>alert('Data inserted');</script>";
}
else
{
echo "<script>alert('Data not inserted');</script>";
}
}
?>
<!DOCTYPE html>

<body>
<h3>Insert Data In Databse</h3>
<form action="" method="post">
<table width="100%" border="0">
<tr>
<th width="26%" height="60" scope="row">Name :</th>
<td width="74%"><input type="text" name="name" value="" required /></td>

<th height="60" scope="row">Email :</th>

<th height="60" scope="row">Contact no. :</th>
<td><input type="text" name="contact" required /></td>
</tr>
<tr>
<th height="60" scope="row">Gender :</th>
<td><input type="radio" name="gender" value="Male" required /> Male
<input type="radio" name="gender" value="Female" required /> Female</td>
</tr>
<tr>
<th height="60" scope="row">Education :</th>
<td><select name="education" >
<option value="">Select</option>
<option value="Primary">Primary</option>
<option value="secondary">secondary</option>
<option value="Graduate">Graduate</option>
<option value="Post Graduate">Post Graduate</option>
</select> </td>
</tr>
<tr>
<th height="60" scope="row"> </th>
<td><input type="submit" value="Submit" name="submit" /></td>
</tr>
</table>
</form>
</body>
</html>
function.php: In this file, we have details of database connection and we will fire a query to submit data to MySQL Database. Please replace the details of the database with your MYSQL server details.
<?php
session_start();
define('DB_SERVER','localhost');
define('DB_USER','root');
define('DB_PASS' ,'');
define('DB_NAME', 'myproject');
class DB_connection
{
function __construct()
{
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME);
$this->database=$connection;
}
public function insertdData($fname,$email,$contact,$gender,$education)
{
$result=mysqli_query($this->database,"insert into student(name,email,phone,gender,education) values('$fname','$email','$contact','$gender','$education')");
return $result;
}
}
?>
Now create the Database with name myproject and just copy and paste the code in MySQL Database. You can change the database name as the requirement. The code below will generate the required tables and insert some dummy records. Feel free to change the table name and remove demo records.
