Getting information from a field

How do i get information from a field and then add it to an if statement?

I have:

PHP Code:

  <?

????: NamePros.com http://www.namepros.com/programming/213141-getting-information-from-a-field.html
if($check==yes){

echo'OK';

}

else {

echo'NO';

}

?>

 
<form name="searchform" method="post" action="check.php">

<input type="text" name="check" id="check" value="<? $check ?>" size="25">

<input type="hidden" name="action" value="check">

<input type="submit" name"submit" value="Check">

</form>

Im going to end up searching a database and if the information thats entered is found, they it will say its found, if not it would say its not found.

Nvm, i got it.

You need to get the variable first via $_POST['name'] access semantics. Nobody in their right mind leaves register_globals on anymore.

For example, to check for a flag called "foo", my php would do this:

Code:

$flag = $_POST['foo'];
if( isset($flag) ) {
  echo "way to go smartguy, you typed \"$flag\".";
}

and my html for bit would look like:
????: NamePros.com http://www.namepros.com/showthread.php?t=213141

Code:

<input type="text" name="flag" />

Now, if someone were to set the flag by typing something in there, it would execute, otherwise not.
