你的测试:

if (isset($_POST['submit'])){

从未验证,因为提交按钮没有名称属性

将其更改为:

<input type="submit" value="Send information" id="submit"/>

<input type="submit" name="submit" value="Send information" id="submit"/>

你打开一个括号

case 'insertion':
            $pattern="/^([A-Za-z]*$/";
            break;

但是你在哪里关闭它?如果您将其更改为,错误可能会消失

case 'insertion':
                $pattern="/^([A-Za-z])*$/";
                break;
