PHP和简码中的Wordpress PHP

Question

I am building a wordpress ecommerce template with Cart66 plugin. Using a Cart66 shortcode inside a php template page, I would like to generate the Post ID inside the shortcode. Can someone please help and tell me if this is possible. Here is the code that I am using.

<?php echo do_shortcode("[add_to_cart item=\\". the_ID() .\\" quantity=\\"user:1\\"]"); ?>

This code will lay inside loop-single.php and above

Thank you!

Answer 1

@silent几乎拥有它，但是应该是get_the_ID()而不是the_ID()因为后面的一个会回显它，因此请尝试：

<?php echo do_shortcode("[add_to_cart item=\"". get_the_ID() ."\" quantity=\"user:1\"]"); ?>

Answer 2

正确的行应该是：

<?php echo do_shortcode("[add_to_cart item=\"". the_ID() ."\" quantity=\"user:1\"]"); ?>

Answer 3

更简单的正确答案：

<?php echo do_shortcode('[add_to_cart item="'. get_the_ID() .'" quantity="user:1"]');?>
