I am usuing your snippet fot search from an url parameter to have immediately a result when using a parameter from url.

If I pass filename.php?list1_colfieldname=searchedterm-
I get everything fine if the column to search is there.

But I get an error, when the column is not there. Sinde I use $_SERVER['QUERY_STRING'] in the urlall parameters are always transfered. I do not like to change this. So is there a possiblity not to use this skript, if the urlparameter is not there:

The snipped I got from you (which works if columnt is there) is:

<!– http://www.domain.com/filename.php?list1_colfieldname=searchedterm–&gt;
<script>
// bind custom reload handler, required for url based filters
$(window).load( function () {
$('#refresh_list1').unbind( "click" );
$('#refresh_list1').click( function (event) {
reloadGrid();
});
});

// new handler for reload button – with postData
function reloadGrid()
{
var grid = $("#list1");

// reset default values of filters
var filters = grid[0].p.postData.filters;
for(var i in filters.rules)
{
var f = filters.rules[i].field;
var d = filters.rules[i].data;
$('input[id="gs_'+f+'"]').val(d);
}

grid.trigger("reloadGrid",[{page:1}]);
}
</script>
<!– snippet for url filter end–>

Could you tell how to stop the script working if column is NOT there?
