Trying to generate error messages from array items, maybe I'm on the wrong track

Beginners - Learning PHP
#1

I need to generate an error message when an invalid date is chosen from select lists. I have set up arrays for the $days,$years,$months but I can’t get my head wrapped around how to set up the error message. For example, a leap year could not be 2/30/2012. This is in 4 files. I am only including the file for the form and the validation. I have commented out one thing I tried, and deleted the code to access the other two files. I feel like I should combine $days,$years,$months into one multidimensional array and I’ve tried but my lack of knowledge keeps me from pulling it all together with the error codes either way. Any help is much appreciated.

This is so very close, but I can tell that it is still scrolling through the indexes because, for example. if I select February 31 2012 it returns this: You entered the following date = 30 1 58. I think maybe I need to switch the two error codes around as well, but I didn’t until I fix the other problem. what do you think I am still missing?
Thanks for putting me back on the right direction.

Hello Odemar, i think there is need to refine both files again with proper logic and syntax. i found that there is many syntax error. please post latest code so i can suggest you much better. ~~SR~~ :) :)
#5

Sorry I took so long to get back, I took a few unexpected days off.
I took your advice and went back through my code. Syntax is not a strong suit with me. Maybe if it was I wouldn’t be here. I did clean it up some though and that got me to understand something about how I was calling from the array and it now holds the dates entered and not the positions in the arrays.

The problem seems to be centered around the loop where I am trying to generate error messages, and or the way in which I have populated the $invalidDate array. As I have it now I don’t get parsing errors when I run it so I think my syntax is pretty good. I have tried several array functions and different loops though and nothing seems to work. l am sorry, but I’m at a loss. Here is what I have now. After this I will be adding functionality to display the zodiac sign images. I have them commented out for now.
