How to use wordpress shortcodes in custom php file?

问题

I want to display wpdatatables(plugin) in my custom PHP file so I wanted to use "do_shortcode()" function but nothing works it just shows white screen.

my php file code:

<?php
    $path = $_SERVER['DOCUMENT_ROOT'];
    include_once $path . '/wp-config.php';
    include_once $path . '/wp-load.php';
    include_once $path . '/wp-includes/wp-db.php';
    include_once $path . '/wp-includes/pluggable.php';
    define('WP_USE_THEMES', false);
    echo do_shortcode("[wpdatatable id=1]");
 ?>

回答1:

I think somehow you are not hitting correct page. Can you try to just echo something in that code? Even if shortcode isn't working you should get echo of [wpdatatable id=1] on screen.

If echo works, that probably means your shortcode isn't returning anything, so check that part also. E.g. create a new page from admin panel and try the shortcode.

Turn on the debug mode, you will get a reason for the white screen. For example, put this code in your wp-config.php and reload the page.

define('WP_DEBUG', true);

Try

echo apply_filters( "the_content","[wpdatatable id=1]");

instead of do_shortcode() and see if that produces the output
