如何通过短代码包含php时发送变量?

I am including a PHP file on a WordPress page like this: [include filepath='/my_file.php'] The part of the functions.php that I changed to make it possible looks like this:

function include_file($atts) {
    extract(shortcode_atts(array('filepath' => NULL), $atts));
    if ($filepath!='NULL' && file_exists( trailingslashit( get_stylesheet_directory() ) . $filepath)){
    ob_start();
    include(get_stylesheet_directory() . '/' . $filepath);
    $content = ob_get_clean();
    return $content;
    }
}

However, I want to be able to send a variable with the include. It is not possible like this: [include filepath='/my_file.php?var=1'], but maybe you get the idea.

Right now, I created a lot of different .php files which have the variables in them and included them like this: [include filepath='/my_file1.php'][include filepath='/my_file2.php'] This is really annoying to deal with and if I change something in the original php, every other one has to be changed. Is there a better way? :)

    You can define a variable before an include statement and that will be visible to the file you are including.

    Simple example (I want to pass $foo into my file):

    inc.php:

    echo "inside inc.php '" . $foo . "' << ...
    ";
    

    test.php:

    function hello()
    {
        $foo = 9999;
        include('inc.php');
    }
    
    hello();
    

    which will output:

    # php test.php
    inside inc.php '9999' << ...
    

    hope that helps.
