Illustration I


Sneakers (heading)

1. Nike (subheadings)
2. Addias
3. Fila

Boots
DressShoes


The illustration above is and accordion menu, which a users click in a heading and it display its subheadings. The equivalent of that illustration in code is below.

$sql = 'SELECT id,Subject FROM menusubjects;'; 
$result = mysql_query($sql); 

if($result && mysql_num_rows($result)!=0) { 
     
    echo '<ul id="nav-categories">'; 
     
    while($row = mysql_fetch_assoc($result)) { 
         
        $uri = 'example1.php?subject='.urlencode($row['id']); 
        $class = !is_null($cat) && $cat==$row['id']?' class="selected"':''; 
         
        echo "\t",'<li',$class,'><a href="',$uri,'">',$row['Subject'].'</a>'; 
             
        if($submenu==false && !is_null($cat) && $cat == $row['id']) { // line 58 
                 
            $sql2 = 'SELECT id,shoename FROM regularmenu WHERE menusubject_id = '.mysql_real_escape_string($cat).';'; 
            $result2 = mysql_query($sql2); 
                 
            if($result2 && mysql_num_rows($result2)!=0) { 
                     
                echo "\n\t\t",'<ul class="submenu">',"\n";     
                 
                while($row2 = mysql_fetch_assoc($result2)) { 
                     
                    $uri2 = $uri.'&menu='.urlencode($row2['id']); 
                    $class2 = !is_null($prod) && $prod==$row2['id']?' class="selected"':''; 
                     
                    echo "\t\t\t",'<li',$class,'><a href="',$uri2,'">',$row2['shoename'],'</a></li>',"\n";                  
                } 
                 
                echo "\t\t",'</ul> <!-- end of ul.submenu -->',"\n";                         
            }                 
            $submenu = true;             
        }              
        echo '</li>',"\n";       
    }      
    echo '</ul> <!-- end of ul#nav-categories -->',"\n 

The code above shows two queries one for the headings and another for the subheadings and both use a while loop etc.

My question is where the pointer is when a user click on the headings Sneakers causing to open it's three subheadings NIke, Adidas and Fila.

Where is the pointer at the beginning of the code or somewhere in the middle or at the end?

What do you mean by pointer? The applications state is being passed between requests through the $_GET vars. Pointer???

ok It is by request ok, I thought there was a pointer that were going through the applications and it was performing it by order. I was mistaken.

Oddz you can visit this post

there I explain more clear what I was trying to achieve with this poing.

Now I know it is by request. I have a question those the request are made by the order of the application or by position in the page?
