Notice: Undefined Index on remote server but not in local testing.

Notice: Undefined index: send in D:\Domains\work ingdata.co.uk\w wwroot\contact_ text.php on line 7

Hi,

I've started getting this error in the contact page form of my website. The web hosting company did an upgrade and it seems to coincide with that.

The Notice is at the top of the page, but the rest of the page displays normally and form still works. I don't get the Notice when I test the page on the local Apache server in the XAMPP installation.

I've checked that the variable is spelled the same throughout the code. I tried using 'submit' as the variable in the IF statement instead of 'send' and got the same Notice.

I'm still new to PHP. I don't understand which element of the code is causing the error, so I'm afraid I've pasted the lot in. It's an IF statement which asks if the send variable is there or not. If it is there, then the form's already been filled in and it displays a "thanks for your question" message, otherwise, if it's not there, it displays the form.

Thanks,

Franc.

Welcome to TSDN. May i suggest changing your line

[PHP]if(!$_POST['send'])[/PHP]

to

[PHP]if(empty($_POST['send']))[/PHP]

The empty command is a more effective command that determines if a string is missing or does not exist.
