    Review And Pursue

    in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)

    Posted

    Oops. I should have put in some /n to make the source code readable. Thought of it just after I posted. Apologies.

     

    Thanks for the comments and for taking the time to reply.

    The double quotes was just silly of me.

    I wish I had thought of using the number _format that way. Just good style from a pro.

    I shall take on board the variable names comments.

    I have now got some more. The code for the ch 2 review and pursue is getting kind of big for posting here but I shall await your feedback on this. I suppose if it is just copied and pasted into and IDE it will be more readable.

    I hope this may be of some use to someone.

    I await your feedback with trepidation.

     

     

    PHP version?

    Hello I'm new around here and i was having trouble with the review and pursue chapter 2. I tried your code Graham and i was getting these errors when executing" Notice: Undefined variable: greeting_error in /var/www/html/php_sandbox/RnP_Chap2.php on line 194

     

    Notice: Undefined variable: age_error in /var/www/html/php_sandbox/RnP_Chap2.php on line 194

     

    Notice: Undefined variable: work_error in /var/www/html/php_sandbox/RnP_Chap2.php on line 194". I am seeing for my self that the variables are defined but i don't understand why it's giving me these errors. Please i will need some guidance.
