Why are My $_POST Values Missing from My PHP Script?

Missing PHP $_POST Values from php://input

Despite receiving form data through a POST request, certain values fail to appear in the PHP $_POST array. Debugging reveals the presence of these values in the raw request string retrieved via php://input.

Cause:

PHP alters field names containing specific characters (spaces, dots, open square brackets, etc.) to comply with the deprecated register_globals.

Solution:

• Disable register_globals: Since this setting is deprecated, disable it in the php.ini configuration file.
• Use a workaround function: Utilize a function that parses the raw request string, extracting and decoding the values to construct a new $vars array containing the missing values. Here's an example:

<code class="php">function getRealPOST() {
    $pairs = explode("&amp;", file_get_contents("php://input"));
    $vars = array();
    foreach ($pairs as $pair) {
        $nv = explode("=", $pair);
        $name = urldecode($nv[0]);
        $value = urldecode($nv[1]);
        $vars[$name] = $value;
    }
    return $vars;
}</code>
