[Resolved] Pages disappear when function is added

Mophilly

I am attempting to modify an existing php project. The main file, index.php, contains a long swith/case statement.

Another file, functions.php, contains a variety of code blocks, aka functions, that perform the real work.

I have added two functions and updated the file index.php.

When I add the second case statement, no html pages will load at all. If I take it out, it returns to proper behavior.

What should I look for, read or grovel for to resolve this.

When you say "no pages will load at all", do you mean that it crashes the server, or times out the server, or simply that nothing appears in the browser window?

It's very elementary, but does "View Source" in your browser show anything at all?

Mophilly

No, there is no source returned to the browser. The browser window display is blank except for controls and such.

The server does not crash.

Removing the functions I have added restores the original behavior.

try posting the functions you are adding and how you are calling them...

OK. I am beginning to see the light. The problems I am having are due to my errors with HTML embedded with the PHP script.

I believe there were two issues:

I must ensure that the html is returned is completed and well formed. So I am now writing all of that first, placing it in the functions and testing the function call.
I was trying to switch in and out of PHP mode to issue snippets of HTML. The PHP script control structures, such as IF and While, are easier to write when "echo" is used rather than attempting to switch modes.

Thanks for replying. Hopefully, my questions will become more suscint as I learn PHP.

ya see, troubleshooting sometimes helps, huh

seriously, troubleshooting/debugging your own code is the best thing you can learn how to do when learning a language, they syntax is just syntax and you can look that up, but when controlling the language to do something, you need to be able to acquire those troubleshooting skills to better hone your overall skills
