TechAirlines: Technology Tips

WordPress has many contact form plugins. The one I use here at Tech Airlines is called Contact Form 7. It’s extremely flexible and easy to use. However, the one thing that has always bugged me was that its 3 scripts (Ajax and 2 jQuery scripts) load on every single page regardless of whether or not its required and only 3 of the pages on this site require it.

This can significantly slow down the loading time of a website. So today, I finally decided to go ahead and try to fix it.

Step 1: Open up your theme’s functions.php (Theme Functions) file.

Step 2: Insert the following code right before the closing “?>” tag.

// Add the Contact Form 7 scripts on selected pages

function add_wpcf7_scripts() {
if ( is_page(array(10,170)) )
wpcf7_enqueue_scripts();
}

// Remove Contact Form 7 scripts elsewhere

if ( ! is_admin() && WPCF7_LOAD_JS )
remove_action( 'wp_print_scripts', 'wpcf7_enqueue_scripts' );
add_action( 'wp', 'add_wpcf7_scripts' );

Step 3: Change the numbers within the array on the highlighted line above (Line 4) to the ID numbers of the pages you want the script to be activated, which would be the pages that contain a contact form. To find out the ID numbers of pages, check the end of the URL when editing the page.

The page ID for the Tech Airlines's Terms of Use page is 187.

Step 4: Save the file and you’re done.

Removing these 3 scripts may slightly improve the loading speed of your WordPress powered site, especially for those with slow network connections.
