delete from database entry PHP script deletes all entries - php

Question

I'm trying to add a delete function for my blog where the logged in user can click on the delete link, but it just does not work.
this is the form for display:
<div id= "blogtitle"><?php echo $title; ?></div><div id= "date"><?php echo $date; ?></div>
<div id="contant"> <?php echo $contant; ?> </div> <p>Delete</p>
this is the deleteblog.php:
delete('blog', $_GET['id']);
header('Location: index.php');
die();
and this is the function:
function delete($blog, $id){
$blog = mysql_real_escape_string($blog);
$id = (int)$id;
mysql_query("DELETE FROM '{$blog}' WHERE 'id' = {$id}");
}
It just does not delete it, I've made it to work before where it did delete all the entries but it still wasn't what I intended it to do.

Answer 1

you have pass the id in delete link
<div id="contant"> <?php echo $contant; ?> </div> <p>Delete</p>

Answer 2

Arun answer is correct. As a plus stop using mysql old functions and use mysqli functions instead. Or even better use PDO.

Answer 3

Try like this
function delete($blog, $id){
$blog = mysql_real_escape_string($blog);
$id = (int)$id;
mysql_query("DELETE FROM $blog WHERE id = $id");
}
And you should pass id in your anchor tag

Answer 4

i have changed that line to what you have given me and i have also changed the delete function to:
'function delete($blog, $id){
$blog = mysql_real_escape_string($blog);
$id = (int)$id;
mysql_query("DELETE FROM $blog WHERE id = $id");
}
and now it comes up saying that the id varieble is unidentify in my anchor tags... :<
