php - Delete not deleting the selected post but its deleting the recently(newels) added post -

-

my update.php file:

<?php ob_start();  session_start();   //declare basic variables $servername = "localhost"; $username = "bilal"; $password = "super"; $dbname = "coursework";   //create connection  $link =  mysqli_connect($servername, $username, $password, $dbname);   //check connection if($link->connect_error){ die ("connection failed: " . $link->connect_error); }  //security purpose, handiling escape string   // $crested_by = $_post ['created_by'];   $title = $_post['title'];   $catagory = $_post['catagory'];   $contact = $_post['contact'];   $comment = $_post ['description'];    $ses = $_session['email'];   $date = date('y-m-d');   $availability = $_post ['availability'];   $price = $_post ['price'];   $id = $_post['wow'];  // $created_by_id = $_session['created_by_id'];   // $username = $_session['firstname'];  if (isset($_post['del'])){   $deletequery=mysqli_query($link,"delete new_post id='$id'");   header ("location: added_posts.php");    }      else if(isset($_post['update'])){     $sql = "update new_post set title='$title', contact='$contact',        availability='$availability', price='$price', comment='$comment'  id='$id'";  if (mysqli_query($link, $sql)){  echo "awesoke";   header("location:added_posts.php");   }else{    echo "error: sign unsuccessfull"; }   }  $link->close();  ?>

this update.php file showing id inside textbox , doing id = text field value. deleting added item deletes if have 3 posts id ( 4, 5, 6) id delete 6 first 5 4. displaying data in bootstrap cards. every delete button under post delete recent 1 added.

so you're trying delete recent record in database?

your problem sql statement you have

"delete new_post id='$id'"

this deleting record in new_post id equal id posted form.

you must consider latest entry in table have largest id.

so use this: 

delete new_post order id desc limit 1

attempt 2:

you want delete specific row based on id?

i suggest use prepared statements security

firstly try this:

$stmt = $link->prepare("delete new_post id= ?"); $stmt->bind_param('i', $_post['wow']); // can use $id  $stmt->execute();  $stmt->close();
