Hi there,

My question is based on this example:
http://www.opencrypt.com/blog.php?a=23

I need to make the static tree menu dynamic with my MySQL database:

ere is my database table structure:
Table name: pages
fields:
id - int 255 auto-increment;
parent_id - int 255;
linklabel - varchar 255;

Please help!

Thanks,

Thanks for the quick reply Zado!

That is only half a solution really, the bits in bold in the code are the bits I need help with too!

Okay, so I threw together an example for you to dynamically create this tree with values from your database via php and mysql. You need to add the source files into your directory and then you can see the syntax from the following code of how to connect to your database to create this menu.

 
<?php
mysql_connect("dbHost", "dbUserName", "dbPassword") OR DIE('Unable to connect to database! Please try again later.');
mysql_select_db('dbName');
$sql = 'SELECT parent_id, linklabel FROM pages';
$result = mysql_query($sql);
$counter = 0;
$label_array = array();
if ($result):
    while ($row = mysql_fetch_array($result)):
        $label_array[$counter] = array("parent" => $row['parent_id'], "linklabel" => $row['linklabel']);
        $counter += 1;
    endwhile;
endif;

function getParent($id) {
mysql_connect("dbHost", "dbUserName", "dbPassword") OR DIE('Unable to connect to database! Please try again later.');
mysql_select_db('dbName');
    $sql = "SELECT linklabel FROM pages WHERE id = '" . $id . "'";
    $result = mysql_query($sql);
    if ($result):
        while ($row = mysql_fetch_array($result)):
            return $row['linklabel'];
        endwhile;
    endif;
}
?>
