он выводит поле авторизации если я не
авторизована, хотя если оставить поле
пустым то всё равно все нормально дальше
проходит. Можно сделать как нибудь чтобы
это поле не выводилось а сразу результат, без авторизации? Или чтобы автоматически
авторизовывал, там эта переменная nickname
или name?
вот код
<?php
session_start();
function createForm(){
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<table align="center">
<tr><td colspan="2">Please eneter a nickname to login!</td></tr>
<tr><td>Your name: </td>
<td><input class="text" type="text" name="name" /></td></tr>
<tr><td colspan="2" align="center">
<input class="text" type="submit" name="submitBtn" value="Login" />
</td></tr>
</table>
</form>
<?php
}
if (isset($_GET['u'])){
unset($_SESSION['nickname']);
}
// Process login info
if (isset($_POST['submitBtn'])){
$name = isset($_POST['name']) ? $_POST['name'] : "Unnamed";
$_SESSION['nickname'] = $name;
}
$nickname = isset($_SESSION['nickname']) ? $_SESSION['nickname'] : "Hidden";
?>
