Why does this not work? I want to be redirected to id?1 and remove.php removes it from table. How is this done?
// Get all the data from the "example" table
$result = mysql_query("SELECT * FROM pages")
or die(mysql_error());
echo "<table border='1'>";
while ($row = mysql_fetch_array($result)) {
echo "<li class='list-group-item'>";
echo $row['header'];
echo "<br/>";
echo $row['description'];
echo "<br/>";
echo "<button type='button' class='btn btn-default btn-xs' style='margin-top:8px;margin-bottom:0px;'>Ändra innehåll</button>";
echo " ";
echo "<form method='POST'><a href='delete.php?". $row['page_id']."' name='action' class='btn btn-danger btn-xs' style='margin-top:8px;margin-bottom:0px;'>Ta bort sida</a></form>";
echo "<td><a href='obrisi.php?id=$id'>Delete</a></td>";
echo "</li>";
}
echo "</table>";
?>
delete.php
<?php
if (isset($_POST['1']))
{
foreach ($_POST['id'] as $page_id)
{
if (!mysql_query("DELETE FROM pages WHERE id = '$page_id'"))
{
echo mysql_error();
}
}
}
?>
Please help me. Thanks in advance.

You can not get the id in POST becuase you are using it as a Query String. You can get it as:
$page_id = intval( $_GET['id'] );
Now you can check it as:
if( $page_id > 0 ){
// your stuff.. use this id in your query
}
What I have changed:
Use $_GET (SUPER GLOBAL) instead of $_POST becuase of query string.
Side Note:
There is no need to use foreach loop becuase it's not an array.
I suggest you to use mysqli_* or PDO instead of mysql_* becuase its deprecated and not available in PHP 7.
