从 wordpress 中的另一个文件获取变量

Question

I'm kind of new to wordpress coding and I've been trying to get a variable from another file.

I have this variable $final_cat_url in /custom/last-category.php that I want to reuse in customtemplate.php.

I've read lots of explanations and the codex, but it's still not working.

I've tried to use the following code in customtemplate.php

get_template_part( 'custom/last-category', null, array('my_final_cat_url'=> $final_cat_url));  
echo $args['my_final_cat_url'];

Can you help me with that? Thanks a lot.

Add this function to your functions.php file:

function includeWithVariables($filePath, $variables = array(), $print = true){
    $output = NULL;
    if(file_exists($filePath)){
        // Extract the variables to a local namespace
        extract($variables);

        // Start output buffering
        ob_start();

        // Include the template file
        include $filePath;

        // End buffering and return its contents
        $output = ob_get_clean();
    }
    if ($print) {
        print $output;
    }
    return $output;
}

Instead of using get_template_part(), use this:

<?php includeWithVariables('file_to_include.php', array('final_cat_url' => $final_cat_url)); ?>

In the file you included:

<?php echo $final_cat_url; ?>
