Membuat File create.php

<?php
// Include config file
require_once "config.php";

// Define variables and initialize with empty values
$name = $address = $salary = "";
$name_err = $address_err = $salary_err = "";

// Processing form data when form is submitted
if($_SERVER["REQUEST_METHOD"] == "POST"){
 // Validate name
 $input_name = trim($_POST["name"]);
 if(empty($input_name)){
  $name_err = "Please enter a name.";
 } elseif(!filter_var($input_name, FILTER_VALIDATE_REGEXP, array("options"=>array("regexp"=>"/^[a-zA-Z\s]+$/")))){
  $name_err = "Please enter a valid name.";
 } else{
  $name = $input_name;
 }

 // Validate address
 $input_address = trim($_POST["address"]);
 if(empty($input_address)){
  $address_err = "Please enter an address.";
 } else{
  $address = $input_address;
 }

 // Validate salary
 $input_salary = trim($_POST["salary"]);
 if(empty($input_salary)){
  $salary_err = "Please enter the salary amount.";
 } elseif(!ctype_digit($input_salary)){
  $salary_err = "Please enter a positive integer value.";
 } else{
  $salary = $input_salary;
 }

 // Check input errors before inserting in database
 if(empty($name_err) && empty($address_err) && empty($salary_err)){
  // Prepare an insert statement
  $sql = "INSERT INTO employees (name, address, salary) VALUES (?, ?, ?)";

  if($stmt = mysqli_prepare($link, $sql)){
   // Bind variables to the prepared statement as parameters
   mysqli_stmt_bind_param($stmt, "sss", $param_name, $param_address, $param_salary);

   // Set parameters
   $param_name = $name;
   $param_address = $address;
   $param_salary = $salary;

   // Attempt to execute the prepared statement
   if(mysqli_stmt_execute($stmt)){
    // Records created successfully. Redirect to landing page
    header("location: index.php");
    exit();
   } else{
    echo "Something went wrong. Please try again later.";
   }
  }

  // Close statement
  mysqli_stmt_close($stmt);
 }

 // Close connection
 mysqli_close($link);
}
?>
