DataTables FixedHeader, DataTables Sorting plugins, search option are no long

Hi,

thanks for your post, and sorry for the trouble.

Could you please post a link to the page with the table that’s not working, so that I can have a direct look? Thanks!

Hi,

thanks for the link! I think that this is related to the script minification in W3 Total Cache. Can you please try again after turning that off. It looks like the jQuery JS library gets garbled by that…

Also, there’s PHP code visible in the page

<?php
wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js');
wp_enqueue_script('jquery');
?> <?php
wp_deregister_script('swfobject');
wp_register_script('swfobject', 'http://ajax.googleapis.com/ajax/libs/swfobject/2/swfobject.js');
wp_enqueue_script('swfobject');
?>

that should not be there. Please check if you see that in your theme’s “header.php” and delete it.

Hi,

ok, thanks for deleting that, and for turning off the minification for now.

Indeed, it looks like this is not the reason for this. Instead, the problem seems to be that the Shortcode is evaluated twice on the page. For the small table, that does not matter, as that’s not using the FixedHeader Extension. The bigger table however does use the FixedHeader Extension, and that doesn’t like being evaluated twice.

You should therefore try to find out why the Shortcodes on the page are evaluated twice. My assumption is that this is done by your theme, so please start by switching to the WordPress default theme TwentyFourteen temporarily.

Hi,

thanks for checking this! That then means that another plugin is causing the double-evaluation of the Shortcode.
If you check near the bottom of the HTML source of the page (“View source” in the browser), you will see this:

$('#tablepress-11').dataTable({"aaSorting":[],"bSortClasses":false,"asStripeClasses":['even','odd'],"bPaginate":false,"bInfo":false});
$('#tablepress-11-no-2').dataTable({"aaSorting":[],"bSortClasses":false,"asStripeClasses":['even','odd'],"bPaginate":false,"bInfo":false});

and that’s too much.

The problem is not directly in the FixedHeader Extension, that’s just affected by this, as the first evaluation of the Shortcode is “thrown away”.

So, if this is not caused by the theme, it’s another plugin. Please try disabling all other plugins except TablePress one by one, until there’s only

$('#tablepress-11').dataTable({"aaSorting":[],"bSortClasses":false,"asStripeClasses":['even','odd'],"bPaginate":false,"bInfo":false});

in the HTML source of the page.

Hi,

great find! 🙂
That’s what’s causing the problem then!

Yes, please contact Joost about this then. I know of many plugins that do the same as TablePress (namely print JavaScript code to the page when the Shortcode is evaluated), so that this likely affects a lot of sites.
I’ll also dive into the WordPress SEO code to see if I can find the exact cause and maybe a workaround.
