Unable to pass a variable value fr one php file to another php file

[ladygandhi]

I'm trying to simulate an online bookstore.

1)The user enters the search details
2)based on the search details the matched books' details (title, author and price) are displayed in a new page.
3)Then, the user clicks a particular book title link, and more info abt the book is displayed in a new page.

The program works fine for step 1 and 2. The problem is in step 3.

search_eg_vs2.php

......
......
while ($row=mysql_fetch_array($result))
{
echo '<tr><td><a href="book_det.php?title='.$row['title'].'">'.$row['title'].'</a></td>
            <td>'.$row['price'].'</td>
            <td>'.$row['author'].'</td></tr>';
}
......
......

code snippet in book_det.php

$_SESSION['title'] = $_POST['title'];

 echo "Sessions: <pre>"; 
 print_r($_SESSION); 
 echo "</pre>";

$sql = "Select * from books where title= '".$_SESSION['title']."'";

    echo "$sql";

$result = mysql_query($sql)or die(mysql_error());

    $row = mysql_fetch_row($result);

    echo "<br>";
    echo "ISBN" . $row[0] . "<br>";
    echo "Book Title".$row[1]."<br>";
    echo "Price" . $row[2] . "<br>";
    echo "Author" . $row[3] . "<br>";
    echo "Publisher" . $row[4] . "<br>";

This is the output when I click on one of the book titles on the table.

Sessions:
Array
(
[title] =>
)

Select * from books where title= ''
ISBN
Book Title
Price
Author
Publisher

The problem is the title is not being passed to book_det.php. How do I solve this?

Thank you.

Can you see the title being passed through the URL? If so, then it's being passed fine. I'm thinking you're just using the wrong superglobal.
$POST['title'] should actually be $GET['title'] if it's coming through the URL

As LordShryku says use:

$_GET["title"] and it will work just fine!

I use that too one my homepage!
