I am making a edit blog option for a website. I am done with the code. Whenever i click the edit button it redirects to the form action file and shows a blank page. Here are my codes.

edit-blog.php

<?php
include_once('header.php');
include_once('sidebar.php');
include_once('controller/BlogController.php');

$_SESSION['ap-old']['title'] = $_POST['title'];
$_SESSION['ap-old']['short_description'] = $_POST['short_description'];
$_SESSION['ap-old']['description'] = $_POST['description'];

$title = (!empty($_SESSION['ap-old']['title'])) ? $_SESSION['ap-old']['title'] : '';
$short_description = (!empty($_SESSION['ap-old']['short_description'])) ? $_SESSION['ap-old']['short_description'] : '';
$description = (!empty($_SESSION['ap-old']['description'])) ? $_SESSION['ap-old']['description'] : '';

?>

        color : #6a994e;
    }

I’m on my phone about to head to bed so I can’t really look into this too deeply tonight, but I would begin by echo’ing debug statements throughout requestHandler.php to see where the failure is happening.

Also instead of:

$post_query = "SELECT * FROM blogs WHERE id = '$post_id' LIMIT 1";
$post_query_res = mysqli_query($con ,$post_query);

do:

$post_query = "SELECT * FROM blogs WHERE `id`=?";
$post_stmt = $con->stmt_init();
$post_stmt->prepare($post_query);
$post_stmt->bind_param("i", $post_id);
$post_stmt->execute();
$post_query_res = $post_stmt->get_result();
$post_results = $post_query_res->fetch_assoc();
$numRows = $post_query_res->num_rows;

to avoid any dirty extra hands on your database :D
