html - Adding a delete button in PHP on each row of a MySQL table -


i trying add delete button on each row can delete record when button pressed. new php , mysql , stack overflow.

below table extract information mysql database , works.

       <table class="table" >        <tr>        <th> staff id </th>        <th> staff name </th>        <th> class </th>        <th> action </th>         </tr>            <?php         while($book = mysqli_fetch_assoc($records)){         echo "<tr>";        echo "<td>".$book['staff_id']."</td>";        echo "<td>".$book['staff_name']."</td>";        echo "<td>".$book['class']."</td>";        echo "</tr>";        }// end while loop

simply using php follows (you can use js)

while($book = mysqli_fetch_assoc($records)){  echo "<tr>"; echo "<td>".$book['staff_id']."</td>"; echo "<td>".$book['staff_name']."</td>"; echo "<td>".$book['class']."</td>"; echo "<td><a href='delete.php?id=".$book['staff_id']."'></a></td>"; //if want delete based on staff_id echo "</tr>"; }// end while loop

in delete.php file,

$id = $_get['id']; //connect db //create query based on id passed table //query : delete staff_id = $id // on success delete : redirect page original page using header() method $dbname = "your_dbname"; $conn = mysqli_connect("localhost", "usernname", "password", $dbname); // check connection if (!$conn) {     die("connection failed: " . mysqli_connect_error()); }  // sql delete record $sql = "delete bookings staff_id = $id";   if (mysqli_query($conn, $sql)) {     mysqli_close($conn);     header('location: book.php'); //if book.php main page list records     exit; } else {     echo "error deleting record"; }
