Question

I’m trying to work around some logic with an issue I have regarding pagination.

I need to build pagination elements based on a SQL query JSON array, which isn’t a big deal, except the way I’ve worked the pagination is that only the “show per page” elements set by a LIMIT argument are being returned.

To try and clear that up, here’s a glimpse at my code.

<form id="hidden">
<input type="hidden" name="limit" value="5" id="hshowpp" />
</form>
<form id="userform">
    <select id="ushowpp">
        <option value=5>5</option>
        <option value=10>10</option>
        <option value=15>15</option>
        <option value=20>20</option>
    </select>
 </form>

Which, when changed, sets off a jQuery

$('#show').change(function() {
    var ushow = $('#ushowpp').val();
    $('#hshowpp').val(ushow);
}

And then the AJAX

var results = $('#hidden').serialize();
var url = '<php? echo JURI::base(); ?>index.php?option=com_mls&task=ListData&format=raw&' + results;
$.ajax({
    url: url,
    dataType: 'json'
});

So the AJAX returns a query of index.php?.....limit=5 or whatever the user has chosen.

Now, that’s the backbone of how it all works. My logic issue is how to get around a pagination issue. The URL that gets sent to the AJAX includes a LIMIT argurment, where when it hits mySQL comes out like SELECT * FROM my_table WHERE 1=1 AND ...... LIMIT 0,5, where the args for LIMIT are the “current page” and “show per page” values. The issue pertains specifically to the where I need to show a total number of pages from the result that does not include the “show per page” limit argument.

If ANY of this makes sense…thoughts?

My solution was to break up the limit parameters into a separate hidden form so and .serlaize() each form either in tandem or on their own depending on what I needed to do. Here’s a fiddle to illustrate my method.
