I purchased a theme and I have been making the changes I want to it. By default, there is a “read “more” link on the post page of the blog for each post. The text showing for the post might be the full post or it might be an excerpt. <\/p>\n

I only want to show the “read more” if there is more to the actual post.<\/p>\n

I found where to make the change in the code (functions.php) but I am very weak in PHP syntax. if I code “echo the_permalink();”, in the conditional code section I get the link to the full post which is what I need. Now I need to concatenate that into an href string but I do not know how.<\/p>\n

<a href="[permalink]">read more<\/a><\/code><\/p>\n

Can someone help me out with this?<\/p>\n

Thanks in advance<\/p>\n","protected":false},"template":"","class_list":["post-2285842","topic","type-topic","status-closed","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/2285842","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/2285842\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=2285842"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
