編輯：形式將觸發PHP代碼，並導致其空數據寫信給我的JSON文件。我怎樣才能讓我的角度形式發送正確的數據到我的PHP代碼？Angular.js，PHP，JSON形式不工作
我是angular.js的新手，我一直沒有在php工作過一段時間，但我正在嘗試構建一個非常簡單的角度表單，並將數據發送到一個php文件，然後寫入信息到JSON文件。角度表單位於不同於php和JSON文件的服務器上。下面是我到目前爲止有：

<h2>AngularJs form</h2>
<p>This is an AngularJs based form. It uses a controller to handle form validation and submission.</p>

角代碼：
/**
* AngularJS module to process a form.
*/
angular.module('myApp', ['ajoslin.promise-tracker'])
.controller('help', function ($scope, $http, $log, promiseTracker, $timeout) {
$scope.subjectListOptions = {
'bug': 'Report a Bug',
'account': 'Account Problems',
'mobile': 'Mobile',
'user': 'Report a Malicious User',
'other': 'Other'
};
// Inititate the promise tracker to track form submissions.
$scope.progress = promiseTracker();
// Form submit handler.
$scope.submit = function(form) {
// Trigger validation flag.
$scope.submitted = true;
// If form is invalid, return and let AngularJS show validation errors.
if (form.$invalid) {
return;
}
// Default values for the request.
var config = {
params : {
'callback' : 'JSON_CALLBACK',
'name' : $scope.name,
'comments' : $scope.comments
},
};
// Perform JSONP request.
var $promise = $http.jsonp('process.php', config)
.success(function(data, status, headers, config) {
if (data.status == 'OK') {
$scope.name = null;
$scope.comments = null;
$scope.messages = 'Your form has been sent!';
$scope.submitted = false;
} else {
$scope.messages = 'Oops, we received your request, but there was an error processing it.';
$log.error(data);
console.log($scope.name);
}
})
.error(function(data, status, headers, config) {
$scope.progress = data;
$scope.messages = 'There was a network error. Try again later.';
$log.error(data);
console.log('name:', $scope.name);
})
.finally(function() {
// Hide status messages after three seconds.
$timeout(function() {
$scope.messages = null;
}, 3000);
});
// Track the request and show its progress to the user.
$scope.progress.addPromise($promise);
};
});
PHP代碼：
<?php
$myFile = "data.json";
$arr_data = array(); // create empty array
try
{
//Get form data
$formdata = array(
'name'=> $_POST['name'],
'comments'=> $_POST['comments'],
);
//Get data from existing json file
$jsondata = file_get_contents($myFile);
// converts json data into array
$arr_data = json_decode($jsondata, true);
// Push user data to array
array_push($arr_data,$formdata);
//Convert updated array to JSON
$jsondata = json_encode($arr_data, JSON_PRETTY_PRINT);
//write json data into data.json file
if(file_put_contents($myFile, $jsondata)) {
//echo 'Data successfully saved';
}
else
echo "error";
}
catch (Exception $e) {
echo 'Caught exception: ', $e->getMessage(), "\n";
}
?>
歡迎來到Stack Overflow！你的問題是什麼？你已經發布了一堆代碼，但沒有說明你面臨的問題，如果你沒有說出什麼問題，我們根本無法提供幫助。考慮[參考]並檢查[幫助]以獲取更多信息，尤其是[問]頁面以及如何編寫[mcve]。如果可以，我期待着提供幫助，但這裏沒有任何事情可以採取行動。 – Delioth
對不起。我想我真的不知道如何詞組這個問題，但我的角形式觸發我的PHP代碼運行，但PHP代碼不寫相應的數據TOT他JSON文件，角碼返回錯誤。我想知道如何解決這個問題？ – kyofanatic1
你的頭銜應該是什麼意思？ Angularjs比php更好，php比json更好？還是你給他們數值？是某種有條件的嗎？或者它只是無稽之談。 –
