Php 将文件保存到服务器

我正在使用

AngularJs

和

PHP

来尝试实现这一点，但它似乎不起作用

我用

WAMP

创建了一个虚拟主机，在我接收所有内容的文件夹中，我创建了一个

uploads

文件夹，我想将通过不同表单上传的文件存储到该文件夹中。问题是每当我执行

PHP

时，文件夹仍然是空的。以下是我使用的代码：

AngularJs

myApp.controller('AdminPromotionsDetailsController', function($scope, $http) {
    $scope.msg = '';
    $scope.msg_type = 'error';

    $scope.savePromotion = function(promotion) {
        $scope.promotion.PromotionPhoto = promotion.PromotionPhoto.name;

        $http.post('save.php', promotion)
        .success(function(data, status, headers, config) {
            if (data == 'success') {
                $scope.msg = 'Success message';
                $scope.msg_type = 'success';
            } else {
                $scope.msg = 'Error message';
                $scope.msg_type = 'error';
            }

        }).error(function(data, status) {
            $scope.msg = 'Error message';
            $scope.msg_type = 'error';
        });
    }
});

PHP

<?php 
    $con = mysqli_connect('ecommerce', 'root', '', 'my_db');
    // Check connection

    if (!$con) {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }

    mysqli_set_charset($con,"utf8");

    $data = json_decode(file_get_contents("php://input"));

    $id = '';

    if(!empty($data->PromotionId)) {
        $id = mysqli_real_escape_string($con, $data->PromotionId);
    }

    $name = mysqli_real_escape_string($con, $data->PromotionName);
    $link = mysqli_real_escape_string($con, $data->PromotionLink);
    $cover = mysqli_real_escape_string($con, $data->PromotionPhoto);
    $date_start = mysqli_real_escape_string($con, $data->PromotionDateStart);
    $date_end = mysqli_real_escape_string($con, $data->PromotionDateEnd);

    $folder = 'http://ecommerce/uploads/';

    move_uploaded_file($cover, "$folder".$cover);

    if(!empty($data->PromotionContent)) {
        $content = mysqli_real_escape_string($con, $data->PromotionContent);
    } else {
        $content = '';
    }

    if ($id != '') {
        $sql = "UPDATE `promotions` SET PromotionName='$name', PromotionLink='$link', PromotionPhoto='$cover', PromotionDateStart='$date_start', PromotionDateEnd='$date_end', PromotionContent='$content' WHERE `PromotionId`='$id'";
        $sql_res = mysqli_query($con, $sql) or die(mysqli_error($con));

        if ($sql_res) {
            print 'success';
        } else {
            print 'error';
        }
    } else {
        $sql = "INSERT INTO promotions (PromotionName, PromotionLink, PromotionPhoto, PromotionDateStart, PromotionDateEnd, PromotionContent) VALUES ('$name', '$link', '$cover', '$date_start', '$date_end', '$content')";
        $sql_res = mysqli_query($con, $sql) or die(mysqli_error($con));

        if ($sql_res) {
            print 'success';
        } else {
            print 'error';
        }
    }
?>

您不能在JSON中发布文件。当您使用
ng file upload
时，您可以使用服务
upload
进行上传。它负责标题，并使您能够跟踪进度。检查我找到了答案，我必须将
$文件夹设置为
$服务器['DOCUMENT\u ROOT']./uploads/'
尝试限制问题。进行调试，您将更快地得到答案。不可能有人会在自己的机器上尝试所有的代码。不，我不希望人们在他们的机器上尝试这些代码，更像是告诉我是否遗漏了导致我的问题的重要内容。因为我对所有这些都是新手，所以我想说的是，人们不能告诉你可能错过了什么，因为它有太多的代码，98%的人会直接点击，因为你根本没有调试，也没有将问题限制在任何方面。检查$data，它是空的吗？@Shank它不是。它包含了我在表单中传递的所有信息。是的，似乎你无法将
http
传递给特定的函数
