Use variables within shortcode

    Hi, I’d like to make the cart buttons more easily updated by assigning variables to the price and title and inserting those into the shortcode. So instead of [wp_cart_button name="Test Product" price="29.95"] I would have something like (this is using the ACF plugin but you could just use custom fields):

    <?php $title = the_field('product_title');
	$price = the_field('product_price');
echo do_shortcode('[wp_cart_button name="'.$title.'" price="'.$price.'"]'); ?>

    This doesn’t work — neither title nor price are registering in the button — is this possible? This way I could call the same product into the Shop page and into sidebars without having to change the shortcode in several places every time there is a product or price change. Thank you!

    Before you enter the variable in the shortcode, make sure it actually has value in it. So echo the following variable content and make sure it actually has some value before you use it in the shortcode:

    $title = the_field(‘product_title’);
    $price = the_field(‘product_price’);

    Hi mra13, thanks for your reply. Yes, I checked that first — the variables do have a value. So I think I have done something wrong inserting them into the shortcode, but haven’t been able to figure out what. Thanks again!

    Ack — my apologies, mra13! You were totally right. the_field was echoing out the field contents, I had to switch to get_field to register the variable. Now all is right as rain. Thank you so much — the site will only be selling two products, via PayPal, so your lightweight simple plugin seems ideal. Thank you!
