WooCommerce 产品简码在函数中不起作用。php

Question

I am working on wordpress shortcode. In the functions.php, I have added following code

add_shortcode('post-footer-note', 'getPostFooterNote');
function getPostFooterNote() {
    return "<div>Hope you find this tutorial useful! <a href='#'>Share this link</a> on Social Media.</div>";
}

and in the post page, I added [post-footer-note] The code works fine. Instead of "Hope you find this tutorial useful" text I want to display WooCommerce products. To show the products on the page, I made few changes in the code

add_shortcode('post-footer-note', 'getPostFooterNote');
function getPostFooterNote() {
    return "<div>[products limit="8" columns="4" category="hoodies, tshirts" cat_operator="NOT IN"]</div>";
}

After making changes, following error is showing.

Your PHP code changes were rolled back due to an error on line 461 of file C:\xampp\htdocs\wordpress\wp-content\themes\twentynineteen\functions.php. Please fix and try saving again.

syntax error, unexpected integer "8", expecting ";"

Answer 1

You have a syntax error in:

function getPostFooterNote() {
    return "<div>[products limit="8" columns="4" category="hoodies, tshirts" 
cat_operator="NOT IN"]</div>";
}

You need to use different quotations like this:

function getPostFooterNote() {
    return do_shortcode("<div>[products limit='8' columns='4' category='hoodies,  tshirts' cat_operator='NOT IN']</div>");
}

You could also flip the quotes (it doesn't matter which is the outer quotation marks (double or single).

As per the error, the second double quote is just before the 8 , and therefore the return is concluded, and a semicolon is expected. Instead 8 is next, and the compiler doesn't know how to parse your code.
