Ok I found a way out !
In fact my code:
<li><a href="content1.php?my_param=my_value">My Tab N</a></li>
is ok... and I get my get variable "my_param" back into content1.php.
Problem was in my drop function, I had to change it:
Before:
- var $list = $( $item.find( "a" ).attr( "href" ) )
.find( ".connectedSortable" );
After:
- var $list = $( $item.find( "a" ).attr( "newAttribute" ) )
.find( ".connectedSortable" );
with newAttribute being of course reported in my code:
- <li><a href="content1.php?my_param=my_value" newAttribute="value">My Tab N</a></li>
Absolutely no idea if this problem comes from my personal code or because of some migration reason (1.8.23 > 1.9.1)
Hope this will help.
