Sorting by dateformat

Hi,

thanks for your question.

That date format is unfortunately not built-in into the DataTables JavaScript library (from https://www.datatables.net), that TablePress uses for the sorting.

It could in theory be added by custom coding, but unfortunately I don’t really know how that would have to look like ?? Sorry.

Can you maybe switch to another date format like

dd.mm.yyyy

or

dd/mm/yyyy

?

Regards,
Tobias

Hi

Unfortunately I can’t (or I just can’t figure it out) switch the format because the date are all scraped from WP blogs “lastbuilddate”

I’ll sleep on it..again

Thx for the fast response

Hi,

ah, ok. I see…
You might try to contact the developer of the DataTables library at https://www.datatables.net. Maybe he can give you the necessary JavaScript code, or at least offer to create it on a professional basis.

Best wishes,
Tobias

Hi Tobis

I’ve managed to change the format: dd/mmm/yyyy (stil not sortable)

I’ve look around datatables.net and found some code:

// Override default implementation for date sorting
jQuery.extend( jQuery.fn.dataTableExt.oSort, {
    "date-uk-pre": function ( a ) {
        var ukDatea = jQuery(a).text().split('-');
        if(ukDatea.length==2){
            var month = ukDatea[0];
        }else{
            month = ukDatea[1];
        }
        if(month=="jan" || month=="Jan"){month=01;}
        else if(month=="feb" || month=="Feb"){month=02;}
        else if(month=="mar" || month=="Mar"){month=03;}
        else if(month=="apr" || month=="Apr"){month=04;}
        else if(month=="may" || month=="May"){month=05;}
        else if(month=="jun" || month=="Jun"){month=06;}
        else if(month=="jul" || month=="Jul"){month=07;}
        else if(month=="aug" || month=="Aug"){month=08;}
        else if(month=="sep" || month=="Sep"){month=09;}
        else if(month=="oct" || month=="Oct"){month=10;}
        else if(month=="nov" || month=="Nov"){month=11;}
        else{month=12;}
        if(ukDatea.length==2){
            return (ukDatea[1] + month) * 1;
        }else{
            return (ukDatea[2] + month + ukDatea[0]) * 1;
        }
    },

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

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

Is it possible to implement the code in the jQuery of the Tablepress sorting extention?!?

/Gunde

Hi,

ah, very cool. Nice find!

To use that in TablePress, I suggest to simply append that code to the files jquery.datatables.sorting-plugins.js and jquery.datatables.sorting-plugins.min.js
After that, the sorting algorithms will be loaded. You will then just have to apply them to the desired column, by adding the following to the “Custom Commands” textfield in the “Features of the DataTables JavaScript library” section on the “Edit” screen of the table:

"aoColumnDefs": [ { "sType": "html", "aTargets": [ "column-4" ] } ]

Change the “column-4” to the correct column number, i.e. change the 4 to the number of the column that contains the dates in the new format.

Hi

Well it works like a charm, sorting dd/mm/yy , dd/mmm/yyyy and dd/mm/yyyy.

But turns out the WP scraper that I use creates blank spaces before and after the output, sow I can’t sort my list. I found another scraper that nearly does the job. (It don’t allow regex before output)
Is it possible to run regex inside the table?

/Gunde

Hi,

so, you mean that your dates turn up like

" 02 Jan 2103 "

instead of

"02 Jan 2103"

(without the quotation marks “, but with the spaces as in the first case?
And due to that, the sorting with the code you found is not working?
Well, you could simply remove the spaces in the sorting algorithm, so that the sorting works. Just replace the line

var ukDatea = jQuery(a).text().split('-');

with

var ukDatea = jQuery(a).text();
ukDatea = jQuery.trim( ukDatea );
ukDatea = ukDatea.split('-');

Hi

In the soucecode it’s like this:
" 02 Jan 2103 "

On the page it’s like this:
"02 Jan 2103"

Really weird.

The scraper plug-in seems not to be updated any more so I’ll try the other one I found that’s up-to-date (but with out any functions).

The .trim didn’t work, but thanks anyway.

Hi,

ah, that’s too bad. Sorry about that ??
I hope that you can find a solution to your problem…

Best wishes,
