I am using htmlspecialchars($_POST[''])
to keep the data submitted with errors on my registration form,
<form method="post" action="<?php echo htmlspecialchars( $_SERVER['PHP_SELF']) ;?> ">
<div>Company</div>
<input type="text" name="user_account" size="20"
value="<?php echo htmlspecialchars($_POST['user_account']); ?>"
placeholder="Company Name">
<input type="submit" name="submit" value="submit">
</form>
but before the page is submitted, I am getting unknown data where I am using the value="<?php echo htmlspecialchars($_POST['user_account'])
.
How can I solve this problem?
