Get Category name from Post ID

To get the category name from a post ID in PHP, you can follow these steps:

  1. Connect to your database using PHP. You can use the mysqli or PDO extension to connect to your database.

  2. Write a SQL query to select the category name from the categories table, using the id field to match the post ID. For example:

SELECT name FROM categories WHERE id = $post_id

  1. Execute the SQL query using the mysqli_query or PDO::query function, depending on which database extension you are using.

  2. Fetch the result from the query and store it in a variable.

  3. Extract the category name from the result using the appropriate function or method, such as mysqli_fetch_assoc or PDO::fetch

  4. You can then use the category name as needed in your PHP code.

Here's an example of how you might put this all together in a PHP function:

<?php

function getCategoryName($post_id, $conn)
{
  $sql = "SELECT name FROM categories WHERE id = $post_id";
  $result = mysqli_query($conn, $sql);
  $category = mysqli_fetch_assoc($result);
  return $category['name'];
}

This function takes a post ID and a database connection as arguments and returns the name of the category associated with the post.
