Datatable date sorting dd/mm/yyyy issue

Update 2020: HTML Solution

Since HTML 5 is so much developed and almost all major browser supporting it. So now a much cleaner approach is to use HTML5 data attributes (maxx777 provided a PHP solution I am using the simple HTML). For non-numeric data as in our scenario, we can use data-sort or data-order attribute and assign a sortable value to it.

HTML

<td data-sort='YYYYMMDD'>DD/MM/YYYY</td>

Here is working HTML solution

jQuery Solution

Here is working jQuery solution.

jQuery.extend( jQuery.fn.dataTableExt.oSort, {
"date-uk-pre": function ( a ) {
    var ukDatea = a.split('/');
    return (ukDatea[2] + ukDatea[1] + ukDatea[0]) * 1;
},

"date-uk-asc": function ( a, b ) {
    return ((a < b) ? -1 : ((a > b) ? 1 : 0));
},

"date-uk-desc": function ( a, b ) {
    return ((a < b) ? 1 : ((a > b) ? -1 : 0));
}
} );
 

Add the above code to script and set the specific column with Date values with { "sType": "date-uk" } and others as null, see below:

$(document).ready(function() {
    $('#example').dataTable( {
        "aoColumns": [
            null,
            null,
            null,
            null,
            { "sType": "date-uk" },
            null
        ]
    });
    });

I know this is an old question and answers are old too. Recently I came across a simple and clean way of sorting dates. It can be done by HTML5 data-order attribute to <td> element.

Here's what I have done in my PHP:

<?php
$newdate = date('d M Y', $myDateTime); // Format in which I want to display
$dateOrder = date('Y-m-d', $myDateTime); // Sort Order
?>

<td data-order="<?php echo $dateOrder; ?>" >
<?php echo $newdate; ?>
</td>

Date Sort - with a hidden element

Convert the date to the format YYYYMMDD and prepend to the actual value (DD/MM/YYYY) in the <td>, wrap it in an element, set style display:none; to the elements. Now the date sort will work as a normal sort. The same can be applied to date-time sort.

HTML

<table id="data-table">
   <tr>
     <td><span>YYYYMMDD</span>DD/MM/YYYY</td>
   </tr>
</table>

CSS

#data-table span {
    display:none; 
}
