Declaring variables

[Anon]

Hi!

I'm doing this Add User page where I'd like everything to be handled by one page.

I use "if ($Submit) {..." to see wether the button has been pressed or not.

The problem is if it hasn't, then I get a "Warning: Undefined variable: Submit in ...."

The script works fine except for that annoying warning.

Any suggestions?

Regards

Does putting an else statement help? That's how I usually write my programs and I don't get that warning message, but then again, maybe you have a newer version of PHP installed.

thanks for replying, but no luck. I still get the warning plus whatever I type in the Else field.

Regs.

I'm pretty sure this has to do with how PHP was compiled.

I get this error on my home installation of PHP but not on any of the websites that I upload my code to.

on the html form clause, you probably write the code :

<input type=submit value="add">

so when the form is submit ,No $submit is declared.

you must write the code such as :

<input type=submit value="add" name="Submit">

so the variabe $Submit has already declared.

It is because you are referencing the variable $Submit when it doesn't exist. Change your if to if (isset($Submit)) { ...

That should work.

you can get rid of notices like this:

error_reporting (E_ALL ^ E_NOTICE);

Disable all errors:

error_reporting (0);

Change error reporting in your php.ini file to change these system-wide.

thank you all for the good comments. yes it was the isset function I had to use. I tried using it for cookies to but strangely no luck there. So I guess the "Disable all errors" comes in handy. =)

And thanks again, ppl!
Much appreciated!
