Trouble deleting a record using PHP. Code included

I Have simple PHP functions that produce html links which should delete a record, however the delete link only manages to refresh the page.

I know the solution is simple but I am new to PHP so could somebody please be kind enough to point me in the right direction? thank you. help greatly appreciated.

fuctions.php

<?php
     include('includes/connect.php'); 
  function getPosts() {
        $query = mysql_query("SELECT * FROM posts") or die(mysql_error());
        while($post = mysql_fetch_assoc($quer开发者_JAVA技巧y)) {
            echo "<tr><td>" . $post['Title'] . "</td><td>" . $post['Author'] . "</td><td><a href=\"delete.php?id=" . $post['ID'] . "\">Delete</a><br /><a href=\"edit.php>?id=" . $post['ID'] . "\">Edit</a></td></tr>";
        }
    }
    function deletePost($id) {
        $id = (int) $id;
        mysql_query("DELETE FROM posts WHERE ID = '$id'") or die(mysql_error());
        header("Location: posts.php");
  }
?>

delete.php

<?php
   include('includes/functions.php');
   deletePost($_GET['ID']);
?>

In your delete.php file, you call:

deletePost($_GET['ID']);

However, in your link you use:

delete.php?id=

It is a case issue, make them both be upper case ID or lower case id.

Check your casing.

You are setting the GET paramets name to id while checking for ID

Print your sql delete command before executing and it I suppose will answer your question.
