passing variables from HTML to PHP

yager

When i use variables from a HTML form on PHP the values come ou as blank.
Even when i put everything in the same file like following code
<html>
<body>
<form>
<input type=text name="name" value="yager">
<?php
echo ("Hello" $name".");
?>
</form>
</body>
</html>

Output: Hellow .

Can someone give a light on this?

thanks in advance,
yager

I think your problem is probably your register_globals settings. If it's set to ON, what you're trying to do should work. If it's OFF (default), then it wont. You should be doing something like this:

if(!empty($_POST)) {

echo $_POST['text'];
} else {

echo "<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">";
echo "<input type=\"text\" name=\"text\">";
echo "<input type=\"submit\" name=\"submit\" value=\"Go\">";
echo "</form>";
}

Yes your code works fine and the global variables were off. I've switched them on but the problem remains.

It is best to have the varibles coming from HTML because the web designers can do all the code for the form and leav only the scripts for the programmers

Any other possibilities or opinions?

I don't think you need to echo everything. You could just put <form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post">

I've noticed a lot of scripts echo everything, and unless the line itself is put into a variable I can't see why that would be helpful (I hope someone can shed some light, because I know there must be a reason why).

Also, if you don't want the html programmer to be bother with massive chunks of php code you could attach a file that has the coding using require() or include(). (http://us3.php.net/manual/en/function.require.php)

That would only be useful for large amount of coding though.
