When you try to run this code, what are you getting back? Error messages? Specifically -- what is working and what isn't?

Well for lab6part2menu.php, when I use Google Chrome it doesn't show any error. Just plain white page. But when I use Mozilla Firefox, it shows me the following. The only thing that it displays is a "Content of your reminders" and a blank table.

 

 

 

Fatal error: Class 'ModFile' not found in /home/student/2009/cst09020/public_html/comp170/Lab6/lab6part2menu.php on line 9

 

 

 

 

For lab6part2decision.php, i see "No selection made. Go back". Go back goes back to lab6part2menu.php

 

For classes.php, it doesn't show any error. Just plain white page.

 

 

Thank you!

lab6part2menu.php:

You initialize your object like this: "$orgFile = new ModFile;" but it looks like your class is called "ModifyFile". Those names have to match up.

 

lab6part2decision.php:

This file only works if you have accessed the lab6part2menu.php file and submitted the form. Otherwise, it will generate the "No selection made" text. Fix the issue above with lab6part2menu.php and then try this again.

 

classes.php:

This file includes the code for your ModifyFile class. It won't show anything in the browser when you view it, so a plain white page is normal.

That kind of helped. It displayed the text below the table like this:

 

Select your option:

Radio button: Add

Radio button: Modify

Radio button: Delete

 

 

Line No. to Delete/Modify = dropdown (doesnt have any values to it... I am assuming it's because the content within the table isn't shown which is indicated by line number 1 to 10 or something.. BUT it has this mean thing:

 

 

 

Notice: Undefined variable: arrayContent in

/home/..../..../..../public_html/..../Lab6/classes.php on line 89
)

 

 

Content to Add/Modify = Hrs [Dropdown from 1:00-24:00]

Mins[Dropdown from 1:00-59:00]

Day [Dropdown from 1-31]

Month[Dropdown from 1-12]

 

Year [Whatever year user wants to input]

E-mail[Whatever email user wants to input]

Message[Whatever message user wants to input]

 

SUBMIT RESET

 

 

 

 

Thanks!
