I’m having a problem with the following piece of code. My desire is to have the heading Search results appear when the form is submitted using the ‘Search’ button, and I’m trying to implement this using the hidden input called searching. The idea is that when the form is submitted, this value is set to ‘yes’, and that will reveal the heading, but that is not what is happening here. Can anyone please tell me where I’ve gone wrong?

<html>
    <head>
        <title>Search</title>
    </head>

    <body>
        <h1>Search</h1>

        <form name = "search" action = "<?=$PHP_SELF?>" method = "get">
            Search for <input type = "text" name = "find" />
            <input type = "hidden" name = "searching" value = "yes" />
            <input type = "submit" name = "search" value = "Search" />
        </form>

        <?php
            if ($searching == "yes")
            {
                echo "<h2>Search results</h2>";
            }
        ?>
    </body>
</html>

    @chris, you dont have to use a hidden field. you just can check if the form was submitted like this:

    if(isset($_GET['search'])) echo 'foo';

    @Boris, why should it be more secure to store the global into another var? I would agree if you check the global against a regex or whatever before.
