WordPress shortcode to export a site, useful if your site is super locked down.

function export_all_posts() {
    // Ensure the export function is available
    if (!function_exists('export_wp')) {
        require_once ABSPATH . 'wp-admin/includes/export.php';
    }

    // Start output buffering
    ob_start();

    // Call the export function
    export_wp();

    // Get the output
    $output = ob_get_clean();

    $filename = "export_" . sanitize_title( get_bloginfo('name') ) . "_" . time() . ".xml";
    
    // Save the output to a file
    file_put_contents(ABSPATH . "wp-content/uploads/$filename", $output);
}
add_shortcode('export_all_posts', 'export_all_posts');
