custom page url slug needs illegal ?id=1 for javascript

Question

I have created portfolio page which contains a image-slid-menu for navigation. For an menu item to appear as open, javascript gets instruction like ?id=0 appended to the url. for instance portfolio/art.php?id=0. However wordpress does not allow url slug containing ? or = for pages. What should I do now? I already setup the slider with these pages working: www.gransar.net/portfolio/ www.gransar.net/portfolio/design

did I complete screw up thinking this could be easily implemented? I'm using the following: http://www.ajaxblender.com/demos/menu/imagemenu/

Answer 1

Here's a potential solution using the page_link filter and testing for the presence of a meta key to add a query arg:

function wpa84303_page_query_arg( $permalink, $page, $sample ) {
    if( $query_arg = get_post_meta( $page, 'query_arg', true ) )
        $permalink = add_query_arg( 'id', '0', $permalink );
    return $permalink;
}
add_filter( 'page_link', 'wpa84303_page_query_arg', 10, 3 );

Add a custom field to the page with the key query_arg and give it any value, if the key exists then ?id=0 will be appended via the add_query_arg function.

Ok... so I read the documentation for the slider and there is a function called Open that I added

<script type="text/javascript"> 
window.addEvent('domready', function(){
var myMenu = new ImageMenu($$('#imageMenu a'),{
openWidth:310, open:1, border:2, onOpen:function(e,i){window.location=(e);}
});

and everything is fine now. thanks everyone.
