Question

我需要将数据编辑为db并使其成为即时视图并使用angular xeditables，但我无法将数据传递给process.php（更新数据库并检索数据）

如何使用$ http.post

传递数据

我不知道这对你或其他人是否有用。 Afaik，你不能使用带有角度的http.post来更新数据库（至少在我的情况下，使用php和mysql）。你需要使用$ http（），如下所示：

var request = $http({
        method: "post",
        url: "include/process.php",
        data: {
            name: $scope.name,
            status: $scope.status,
            group: $scope.group
        },
        headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
    });

然后，在PHP中，检索它：

<?php
    $postdata = file_get_contents("php://input");
    $request = json_decode($postdata);
    @$name = $request->name;
    @$status = $request->status;
    @$group = $request->group;
    ...
?>

使用$ name，$ status和$ group的值，您将能够更新数据库。

更新：您的process.php未被调用，因为您有＆＃34;返回$ http.post（＆＃39; / saveUser＆＃39;，$ scope.user）＆＃34; $ scope.saveUser = function（）中的第一行，它立即结束saveUser函数的执行。见return statement in Javascript：

在函数中调用return语句时，将停止执行此函数。如果指定，则将给定值返回给函数调用者。如果省略表达式，则返回undefined。
