Hello,
I have been having problems with some code I am writing and have not been able to figure out what I am doing wrong, even after some debugging.
I have a textbox that users can input any letters into, that should should search the item field boxes and highlight any matching strings. If a matching search is made, then the item box should remain yellow, and the other item boxes should be white.
It does not have to be a perfect match. Any letter that matches, such as the letter '"j" in the word "juice" should be enough to make the item field box, highlight yellow.
I am including my code but have not been able to figure out how to use this code:
str_ireplace($targetstring, '<span style="background-color:#ff0000;">' . $targetstring . '</span>', $item_value);
(I must be doing something wrong) Any help with this would be greatly appreciated.
Thanks.
