Search both the post content and title – possible solution
-
Hi,
I wanted to be able to search the post_content as well as the post_title so I have edited the plugin (needs testing fully), but seems to work so far.
Because it searches through the content, the title may no longer contain the highlighted search terms. Also in the widget there is an new checkbox option for Search Type: Title or Title and Content.
I have marked all the new lines of code with // NEW: START and // NEW: END.
NOTE: This is just a guess but I am not sure about the number 2 in the following might relate to the widget number so may not work for everyone. So there maybe a better option. Even limiting the widget to being used once if that’s possible?
