Create Function to Insert Post using core PHP


Hello there, In this tutorial we will learn how to create function to insert post to database using php. here's an example function to insert a post using PHP's core SQL functions:


function insertPost($title, $content, $author) {
  // Connect to the database
  $conn = mysqli_connect("localhost", "username", "password", "database_name");

  // Check if the connection was successful
  if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());

  // Escape the input data to prevent SQL injection attacks
  $title = mysqli_real_escape_string($conn, $title);
  $content = mysqli_real_escape_string($conn, $content);
  $author = mysqli_real_escape_string($conn, $author);

  // Construct the SQL query
  $sql = "INSERT INTO posts (title, content, author) VALUES ('$title', '$content', '$author')";

  // Execute the SQL query
  if (mysqli_query($conn, $sql)) {
    echo "Post inserted successfully!";
  } else {
    echo "Error inserting post: " . mysqli_error($conn);

  // Close the database connection

You can then call this function with the appropriate values for the title, content, and author of the post you want to insert, like this:

insertPost("My first post", "This is the content of my first post.", "John Doe");

Note that this is just a simple example and you should always validate and sanitize user input to prevent security issues.
