I'm trying to use htmlspecialchars() to escape apostrophe foreach(htmlspecialchars($_POST) as $key=>$val) { but it's not escaping / working. Am I placing it in the wrong place?

 

thanks in advance

if(isset($_POST['save_your_application']) || isset($_POST['save_progress'])) {

	$errors = 0;
	$detailsArray = array();
	$insertArray = array();

	foreach($_POST as $key=>$val) {
		$stringDivide = explode("_", $key); // Break up key name
		$type = end($stringDivide); // Get the TYPE of field
		$fullKey = $key;
		//$key = substr($key, 0, -4); // Get the field name (deleting the TYPE from the end)

		// IF FIELD IS A NUMBER
		if(strcmp($type, "num") == 0) {
			$array = array();
			$array['key'] = $key;
			$array['value'] = (int)$val;
			if($val == "")
				$array['value'] = NULL;
			$array['type'] = $type;
			$insertArray[] = $array;
		}

		// IF FIELD IS TEXT
		elseif(strcmp($type, "txt") == 0) {
			$array = array();
			$array['key'] = $key;
			$array['value'] = $val;
			$array['type'] = $type;
			$insertArray[] = $array;
		}

		$detailsArray[$fullKey] = $val;

	}
	if(isset($_POST['save_progress']) && $_POST['save_progress'] == 1) { $status = 3; } else { $status = 2; }


	if(isset($_POST['other_user'])) { $userID = $_POST['other_user']; }
	elseif(isset($_GET['other_user'])) { $userID = $_GET['us']; }
	else { $userID = $_SESSION['ID']; }


	// THIS IS WHERE WE SEND STUFF TO DB
	applicationSubmit($userID,$insertArray,$status);
	if($userID == $_SESSION['ID'] && $status == 2) {
		send_email($_SESSION['ID'],"has completed their application.");
	}
	if(isset($_POST['save_your_application']))
		$sent = 2;
	else
		$sent = 1;

} else {
	if(isset($_GET['other_user'])) { $userID = $_GET['other_user']; } else { $userID = $_SESSION['ID']; }
	$application = getUserApplication($userID);
	$detailsArray = array();

	if(is_array($application)) {
		foreach($application as $key=>$val) {
			if(is_numeric($key)) {}
			else {
				if(strcmp($key, "id") == 0 || strcmp($key, "fk_userid") == 0 || strcmp($key, "status") == 0 || strcmp($key, "submit_date") == 0 ) {
					$detailsArray[$key] = $val;
				} else {
					$detailsArray[$key] = decrypt_app($val,$GLOBALS['SITE_CONFIGURATION']['KEY_APP']);
				}
			}
		}
	}

	//$detailsArray['status'] = getApplicationStatus($_SESSION['ID']);

	//print_r($detailsArray);
}

Passing $_POST to htmlspecialchars will never work. That is because htmlspecialchars is expecting a string value, not an array - $_POST is a superglobal array containing the values submitted by your form.

 

If you want to apply htmlspecialchars to all the values in $_POST then use array_map. Alternatively apply htmlspecialchars to $val inside the foreach loop.

depending on how your $_POST is organized - assuming its two dimensional and not a multi-dimensional array of array, you could use the following to process your input.

$postArray = array();
foreach ($_POST as $key=>$value) {
  $postArray{$key} = filter_var($_POST[$key],FILTER_SANITIZE_FULL_SPECIAL_CHARS); //same as calling htmlspecialchars
}

This will create a array with sanitized values.  Prototype would be something like

 

Array ( [save_progress]=>value, [other_user]=>value, [save_application]=>value...)
