I am on a class assignment that is past due, I've been at this problem for several days straight and can't figure it out.
Here is the webpage for my assignment I created, play with it and you'll know what I mean:
http://alvinsanchez.com/Assignment4.php
Here is my orders.txt file exactly as it is in the text file (the file that has my menu elements delimited by tabs):
1Nachos Grande8.99
2Meano Burrito7.99
3El Nino's Pasta8.49
4Horchata Tea1.99
5Le Creme Pie3.49
6Champ's Meal9.99
7Veggie's Stew4.99
Assignment: Have the script read the menu from your data file. Ready the file into an array, then use the array to generate the menu on the HTML form. (I've got this part done).
below is my script and in ALL CAPS, BOLD AND RED are my comments in problem places:
