Parameter setting of function get_term_link in WordPress

Recently, to help a friend write an enterprise theme, I need to set a special post type called product for the product. In order to manage the convenience, I set up a special classification type and label type for product, which is product_cat (the classification type of WordPress itself is category).

Why use get_term_link?:?

The new type of classification cannot link the address with the output classification, you need to use the get_term_link () function, which is used as follows:

Refer to WordPress Codex: http://codex.wordpress.org/Function_Reference/get_term_link for more information

Question:

For example:

-the variable of the custom classification ID is $term,$term, which is changed according to the background setting. For convenience, the background parameter is assumed to be $custom_term = 8.

It seems to be true, but here comes the problem, which returns an error:

Here's how it works:

(Bolo sitting on the sofa Note: intval ($term, 10) will be better, otherwise there will be a binary conversion problem when the $term value is too large, or use (int) $term)

Therefore, in the future, when you encounter a function like this, you have to consider whether it is a variable data type problem.

Play around (end).
