Deleting Data from the Database Using GET Requests

Let's now delete records from the database by passing the id for deletion via GET parameters.

Suppose we have a GET parameter named del. Let's get the id for deletion into a variable:

<?php
	$del = $_GET['del'];
?>

Let's form a deletion query:

<?php
	$query = "DELETE FROM users WHERE id=$del";
?>

Delete the record from the database:

<?php
	mysqli_query($link, $query) or die(mysqli_error($link));
?>

Make it so that in the address bar it is possible to send a GET request with the user's id and this user gets deleted from the database.

Modify the previous task so that the page has links to delete each user:

<a href="?del=1">user1</a>
<a href="?del=2">user2</a>
<a href="?del=3">user3</a>

The links, of course, should be generated in a loop from the data received from the database.

Modify the previous task so that you have the following HTML code:

<ul>
	<li>user1 <a href="?del=1">delete</a></li>
	<li>user2 <a href="?del=2">delete</a></li>
	<li>user3 <a href="?del=3">delete</a></li>
</ul>

Modify the previous task so that you have the following HTML code:

<table>
	<tr>
		<th>id</th>
		<th>name</th>
		<th>age</th>
		<th>salary</th>
		<th>delete</th>
	</tr>
	<tr>
		<td>1</td>
		<td>user1</td>
		<td>23</td>
		<td>400</td>
		<td><a href="?del=1">delete</a></td>
	</tr>
	<tr>
		<td>2</td>
		<td>user2</td>
		<td>25</td>
		<td>500</td>
		<td><a href="?del=2">delete</a></td>
	</tr>
	<tr>
		<td>3</td>
		<td>user3</td>
		<td>23</td>
		<td>500</td>
		<td><a href="?del=3">delete</a></td>
	</tr>
</table>
