php in html table?

Anon

first I am very new to php so speak slowly and use little words 🙂

I have a basic text box redirect.
the user enters their domain and and they are taken to a specified page in that domain.

this one works fine:
<pre><?
function myform() {
global $PHP_SELF;
?>

<form action='<? echo $PHP_SELF; ?>' method='post'>
<input type='text' name='myurl'>
<input type='submit' value='submit' name='submit'>
<input type='hidden' value='go' name='action'>
</form>

<?
}

if (! $action) { myform(); }
else if ($action == "go") { header("Location: http://$myurl/users/webmail/cgi-bin/WebMail/index.cgi"); }
?>
</pre>

ok when I try to put it in a html table it tells me: header already sent.....

this one does not work:

<pre>

<form action='<? echo $PHP_SELF; ?>' method='post'>
<input type='text' name='myurl'>
<input type='submit' value='submit' name='submit'>
<input type='hidden' value='go' name='action'>
</form>

<?
}

if (! $action) { myform(); }
else if ($action == "go") { header("Location: http://$myurl/users/webmail/cgi-bin/WebMail/index.cgi"); }
?></td>
</tr>
</table>
</pre>

can anyone tell me why it does not work in a table?

thanks!

the header() function must be called before any html is sent.

move the else if ($action == "go") control statement to the top of the page as a if statement.

You coule also enable output buffering. No output will be sent to the browser until the script is finished. Obviously, the new header will be sent before this happens.

If your version of PHP (4.? -- check the manual) supports this feature, just call 'ob_start()' at the beginning of the script.

thank you both for your help!

moving the ($action == "go") did the trick.

I'll have to do some reading on the 'ob_start()' function.

thanks.
