I am creating a Blog system in PHP with an MYSQL database. I have used a tutorial "Create a blog using PHP and MYSQL database". I am getting an error "Fatal error: Call to a member function execute() on boolean in C:\xampp\htdocs\newssite\amp\article.php on line 6" . I have tried many solutions. I am tired of how to fix this "Fatal error: Call to a member function execute() on boolean" error in PHP. 

I am attaching my PHP source code -

<?php include 'header.php' ?>

<div class="content-div">


                        include "config.php";

                 $sql = $connect->prepare('SELECT id, content, title, title_slug, image_url, created_at FROM posts WHERE title_slug = :title_slug');

                 $sql->execute(array(':title_slug' => $_GET['id']));

                        $result = mysqli_query($connect, $sql) or die("Query Failed.");

                        if(mysqli_num_rows($result) > 0){

                          ($row = mysqli_fetch_assoc($result))


                        <h2><?php echo $row['title']; ?></h2>

                        <amp-img src="<?php echo $row['image_url']; ?>" alt="Welcome"  height="200" width="330"></amp-img>

                         <p><?php echo $row['content']; ?></p>




                          echo "<h2>No Record Found.</h2>";




Kindly fix this issue.

The main possibility of your issue is the connection file. I think there is an issue with your connection (config code ). Where is your config file code? 

Check your connection parameters and make sure to correct them. If you will get this "

Fatal error: Call to a member function execute() on boolean "  error again then, edit your question description. Add your connection file code also.

The errors help to improve coding skills. You are getting a fatal error: Call to a member function.  I tried your code and reviewed Create a blog using PHP and MYSQL database the article link. I think you are getting an issue with your connection file. 





$db = new PDO("mysql:host=".DBHOST.";dbname=".DBNAME, DBUSER, DBPASS);


 $user = new User($db); 

//set timezone- Asia Kolkata 


$user = new User($db); 


You should check your connection details. If you have any other issues, comment here.
