Hi,

One more question, about the required field, would I just add the same code again for another field, but change the name to the new one

Or would I just add the code

You would have to add entirely different IF statements... OR

Is the header("location: {xxx}"); command the only command that enables you to navigate between different html pages? The reason I ask is that I've had trouble using it because it will fail if I try to have any output (eg echo) prior to going to another page. I'd like to be able to display a message, but it messes up the subsequent header command.

The point of header is it changes the browser's header information BEFORE the page loads (so it's not simply loading a page and reloading, it just makes the browser go to entirely different page).

If you use a HTML or Javascript method of redirection, it will break the history process. If they hit the back button, it will send them straight back to the page they are currently on. Not a good thing for usability.

If you want, you can configure PHP to not output anything on the page until after the page has been processed, that way if there is anything to redirect to, it will do it before sending information regardless of where that information is...

To do this, at the top of your page put

Do the ob_start(); and ob_end_flush(); go into my html form or the php code? What I'm trying to do is to display an error message to the user if I detect a problem with an empty field.

Incidentally in grappling with php, I find it difficult selecting suitable functions for whatever task I'm trying to perform. Looking through http://php.net/,

it just lists all the functions in alphabetical order. So you seem to have to laboriously sequentially read what each one does until you (may) find one that performs the required task. There doesn't appear to be any search by keywords to narrow this task down.

The function itself is often a keyword, but if you're looking for something like that you might do better doing a Google search for it.

the ob_start(); and ob_end_flush(); are PHP functions, and so go in PHP tags, before and after the HTML.

OK, I've now got an html page containing my form and a sendmail.php program. In the php code I have defined a function
function checkData()
It validates the form fields and if they pass it allows sending of the mail. If they do not pass, I build up an error message variable $message. If the check fails I want to display the variable $message on the html form page and invite the user to retry.

I can't see how to do this because if I
echo $message
it appears on a page by itself rather than on the form page. Also I get that problem with the header command not working after echo.

A further minor problem is that when I build up my string $message, I want to have a newline after each item. However the command:
$message = $message . "text \n"
seems to ignore my newline \n. What's going wrong here?

The newline '\n' will generate a new line, but for there to actually be a line break you need to 'echo' the HTML <br /> tag.

i.e.
