[Resolved] Undefined Variable error when updated from 4.0.0 to 4.3.7 - WHY?

[sherry]

Hello.

I just updated PHP from 4.0.0 to 4.3.7 via Apache 1.3.12. The variables that worked fine in 4.0.0 are now undefined. I am only using simplistic statements in a form such as,

$first_name = "xxx";

<input type="text" size=35 Maxlength=35 name="required_first_name" value = "<?php print $first_name; ?>">

What changed?

Thank you.

All variables are giving that error? I'm not really sure what might be doing that, but if it's just variables you got from a form, register_globals changed from being on to off. Now you'll have to use $_POST['first_name'] instead of $first_name.

Thank you for your reply.

The 'undefined variable' error is caused when form is 'submitted'.

This error showed up for each variable assigned in the form with 'value = "<? php $var_name ?>">'... where the $var_name was predefined in this format, as an example:

<? php
$var_name = "var_value";
?>

Thanks.

Mordecai's got the right idea. For more detail, have a look at the FAQ in the Newbies' forum. Question One.

Thank you for your reply.

I looked at phpinfo() and register_globals is 'off.' I then put the form vars in $POST[' '] but now I get an error message, "Undefined Index" for each of the vars inside of $POST[' '].

What's going on, now?

Thank you.

I believe I know how this works now - how to prevent from generating the 'Undefined Variable' and 'Undefined Index' error messages. I explained it in the post on 7/2/04,
