Hi everyone,
I currently have an assignment which I am almost done with but am having problems trying to figure out how to integrate a string function search. I have a text box called $targetstring. My program allows users to input items such as groceries into one text box (item_value) and add an amount to the groceries purchased (amount_value).
The program will add the amounts and give a total and will validate the amount_value box for inputs that are not numerical and give an error count if anything other than a number is entered.
I have also added to radio buttons that let you sort the array of values into ascending or descending order.
Everything works fine but I am trying to add one other feature. A text input box called $targetstring that will allow a user to input any text, be it a phrase, letters or single letter and then the program will search all the values input into the item_value text boxes and will highlight them yellow if they match any of the variables entered into the $targetstring input box.
I have included my code. This last part of the assignment is driving me crazy so any help would be greatly appreciated.
Thanks,
Mike
