Question

当我点击保留时，$ page =保留。但当我点击另一个表格如GO时，$ page值将返回Schedule。

如果单击“保留”并且单击“GO $”页面仍然等于“保留”，我想保留$ page的值。

<?php 

if(isset($_POST['page'])){
    $page = $_POST['page']; 
}
else $page = 'Schedule';

echo $page;
?>

<form action="<?php $_SERVER['PHP_SELF'] ?>" method="post">
    <input type="submit" name="page" value="Schedule" />
    <input type="submit" name="page" value="Resereved" />
</form>
<br /><br />
<form action="<?php $_SERVER['PHP_SELF'] ?>" method="post">
    <input type="text" value="" />
    <input type="submit" name="submission" value="GO" />
</form>

请帮助我坚持这一天..
