我似乎无法访问此功能
当我从index.php调用下面的两行时，应该将模型的当前ID设置为999。当我检查数据库时，它为0。
无论我如何从Model类源代码中更改变量的值，该变量的值都会显示在数据库中。
如果包括两个文件中的所有源代码。如果您能找到我不能使用模型类的setCurrentUserId函数的原因，我将不胜感激。
$model = Model::getInstance();
$model->setCurrentUserId(999);
public function setCurrentUserId($user_id) {
$this->currentuserid = $user_id;
}

1 个答案:
答案 0 :(得分：0)
我在index.php的开头尝试了以下内容：
include_once("Globals.php");
include_once("Model.php");
$m = Model::getInstance();
echo $m->setCurrentUserId(1);
echo $m->getCurrentUserId(1);
它回显“ php -S localhost”中的预期“ 1”：
这似乎很明显，但是，在检查值时是否使用了Post请求？另外，它是否具有登录参数？用户名？密码？，我宁愿检查那些条件是否正常，因为在代码开始时可以成功调用de function。
