adding a delete button in php

I have created a table of items that are in my DB, it comes out perfectly however I would now like to add a delete button in another column of the data I am outputting.

However I am just not sure how to do it, I do have a uniqueid for each of the tables so could I use that as the id or what ever you would call it of the button?

<?php

//Start session
    //... all the connection stuff here


$result = mysql_query("SELECT * FROM feathermattresstoppers");

echo "<table border='1'>
<tr>
<th>name</th>
<th>old price</th>
<th>price</th>
<th>delete</th>
</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td>" . $row['name'] . "</td>";
  echo "<td>" . $row['old_price'] . "</td>";
  echo "<td>" . $row['price'] . "</td>";
echo "<td>"<!-- how could I add a button here? -->"</td>";
  echo "</tr>";
  }
echo "</table>";

?>

any help would be appreciated.

Answer

Before your table:

<form action="" method="post">

and close the form tag after your table.

Place this code as your delete button:

echo '<td><button type="submit" name="deleteItem" value="'.$row['id'].'" />Delete</button></td>"';

In PHP you should do the following

<?php

if(isset($_POST['deleteItem']) and is_numeric($_POST['deleteItem']))
{
  // here comes your delete query: use $_POST['deleteItem'] as your id
  // $delete = $_POST['deleteItem']
  // $sql = "DELETE FROM `tablename` where `id` = '$delete'"; 
}
?>
