I'll start by saying that I've seen several similar questions asked but I've yet to find a solution to my problem.

I have the following on a page called test.php.

<!DOCTYPE html>
<html>
    <head>
        <title>Test</title>
        <meta charset="UTF-8">
    </head>
    <body>
        <p><?php print_r($_POST); ?></p>
        <hr />
        <p><?php echo empty($_POST) ? 'Empty' : 'Not empty'; ?></p>
        <hr />
        <form action="test.php" method="post">
            <input id="example" type="text" />
            <input id="submit" type="submit" value="Send" />
        </form>
    </body>
</html>

After submitting the form with text in the input, the $_POST array is always empty. Since several answers I've seen have mentioned PHP settings, I've copied my php.ini file below.

register_globals = off
allow_url_fopen = off

expose_php = Off
max_input_time = 60
variables_order = "EGPCS"
extension_dir = ./
upload_tmp_dir = /tmp
precision = 12
SMTP = relay-hosting.secureserver.net
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

If it matters, I'm using GoDaddy hosting and haven't modified the default settings in any significant way. Any help would be appreciated.

You need to be using the name attribute, not the ID attribute. If no elements have a name attribute, no data will show up in the array.

    <form action="test.php" method="post">
        <input name="example" type="text" />
        <input name="submit" type="submit" value="Send" />
    </form>

OMG. I thought I was going nuts. Its amazing the small details we can forget about simple HTML. Thanks. –  zkent Oct 18 '13 at 6:04

Use the name attribute instead of or as well as id

<input name="example" id="example" type="text" />

The name attribute is used when sending data in a form submission. So you must have to specify the name attribute.

<input id="example" name="example" type="text" />
<input id="submit" type="submit" value="Send" />
