Question

我正在使用SQLite作为本地数据库在AngularJS中构建应用程序。连接由PHP完成。我可以读取数据，我可以添加数据但是当我想删除数据时，我收到500内部错误。以下代码是我在项目中使用的代码。

app.js

$scope.remove = function() {
        var removeIds = helperFactory.filterFiledArrayByDone($scope.items, 'id', 1);

        if (removeIds.length > 0) {
            $http({

                method : 'POST',
                url : urlRemove,
                data : "ids=" + removeIds.join('|'),
                headers : {'Content-Type' : 'application/x-www-form-urlencoded'}

            })
                .success(function(data){
                    if (_recordRemovedSuccessfully(data)){
                        $scope.items = $scope.items.filter(function(item) {
                            return item.done == 0;
                        });
                    }
                })
                .error(function(data, status, headers, config){
                    throw new Error('Something went wrong with removing')
                });
        }
    };

remove.php

<?php

try {

    if (empty($_POST['ids'])) {
        throw new PDOException("Invalid Request";
    }

    $ids = $_POST['ids'];
    $idsArray = explode('|', $ids);
    $placeholders = implode(', ', array_fill(0, count($idsArray), '?'));

    $objDb = new PDO('sqlite:../database/database');
    $objDb->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "DELETE FROM 'items'
            WHERE 'id' IN ({$placeholders})";

    $statement = $objDb->prepare($sql);

    if (!$statement->execute($idsArray)) {
        throw new PDOException("The execute method failed");
    }

    echo json_encode(array(
        'error' => false

        ), JSON_HEX_TAG| JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP);

} catch(PDOException $e){
    echo json_encode(array(
        'error' => true,
        'message' => $e->getMessage()
        ), JSON_HEX_TAG| JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP);
}

的index.html

<div class="columns">
                    <div class="flr">
                        <button type="button" class="small button primary" ng-click="remove()"><i class="fa"></i>Remove</button>    
                    </div>
                </div>

有谁知道如何解决这个问题？

也许我错了，这不是问题，但你错过了一个＆＃39;）＆＃39;在这里：

if (empty($_POST['ids'])) {
    throw new PDOException("Invalid Request";
}

SQLite DB上的AngularJS POST，PHP内部错误500
