我有一个AJAX调用,让我的JSON在我的JSON文件中看起来:
{
"main_object": {
"id": "new",
"formData": "language=nl_NL&getExerciseTitle=test&question_takeAudio_exerciseWord%5B0%5D=test&Syllablescounter%5B0%5D=test&Syllablescounter%5B1%5D=test"
}
}
但是我想这样(这是在我改变我的AJAX调用之前:id: getUrlParameter('id')
:
{
"main_object": {
"language": "nl_NL",
"getExerciseTitle": "asd",
"question_takeAudio_exerciseWord": ["asd"],
"Syllablescounter": ["ASDasd", ""]
}
}
我要添加的唯一内容是"id": "new"
,但是当我这样做时(使用id: getUrlParameter('id')
它会获取ID,但它会弄乱我的代码。
这是我的AJAX调用(当我使用它时,我的JSON开始看起来像第一段代码)
function saveExerciseAjaxCall() {
$("#my_form").on("submit", function(event) {
event.preventDefault();
$.ajax({
url: 'saveJson.php',
type: 'POST',
data: {
id: getUrlParameter('id'),
formData: $('#my_form').serialize()
},
dataType: 'json',
}).done(function(response) {
});
});
}
如何实现这一目标?我知道这不是我saveJson.php
的问题。我知道这是我的AJAX调用,因为它在我添加id: getUrlParameter('id')
时开始显示为第一段JSON代码。
编辑:因为有人说它可能是我的PHP代码..这是我的PHP代码:
<?php
include_once('database_json.php');
$data = $_POST;
//Setup an empty array.
$errors = array();
if (isset($data)) {
$newExerciseData['main_object'] = $data;
$exerciseArray = $data['main_object'];
$databaseFile = 'json_files/database.json';
$textContent = file_get_contents($databaseFile);
$database = json_decode($textContent, true);
if ($data['id'] === 'new') {
if (count($database['data']) == 0) {
$ID = 0;
} // ending database['data'] count 0.
else {
$maxID = max($database['data']);
$ID = ++$maxID["id"];
} // ending the max ID else statement.
$newJsonFile = 'jsonData_' . $ID . '.json';
$newJsonFilePath = 'json_files/' . $newJsonFile;
//Create new database exercise_txt
$newArrayData = array(
'id' => $ID,
'exercisetitle' => $data['formData']['getExerciseTitle'],
'language' => $data['formData']['language'],
'file' => $newJsonFile
);
$database['data'][] = $newArrayData;
file_put_contents($databaseFile, json_encode($database, JSON_UNESCAPED_UNICODE, JSON_PRETTY_PRINT));
file_put_contents($newJsonFilePath, json_encode($newExerciseData, JSON_UNESCAPED_UNICODE, JSON_PRETTY_PRINT));
} // } op regel 34 lijkt verdwaald...?
else {
$index = array_search((int) $_POST['id'], array_column($database['data'], 'id'));
$correctJsonFile = 'json_files/jsonData_' . $_POST['id'] . '.json';
$newJsonFile = 'jsonData_' . $_POST['id'] . '.json';
$newJsonFilePath = 'json_files/' . $newJsonFile;
//Create new database exercise_txt
$newArrayData2 = array(
'id' => (int) $data['id'],
'exercisetitle' => $data['formData']['getExerciseTitle'],
'language' => $data['formData']['language'],
'file' => $newJsonFile
);
$database['data'][$index] = $newArrayData2;
file_put_contents($databaseFile, json_encode($database, JSON_UNESCAPED_UNICODE));
file_put_contents($newJsonFilePath, json_encode($newExerciseData, JSON_UNESCAPED_UNICODE));
} // closing off the else statement
echo json_encode($newExerciseData, JSON_UNESCAPED_UNICODE);
} //closing off the if isset.
?>

您可以使用parse_str($str, $output);
它可以帮助您实现所需。
请注意,parse_str接受两个参数,第一个是字符串(get Parameters),第二个是返回结果的数组。你可以使用以下代码
parse_str($str, $output);
echo json_encode($output);

问题是如何处理formData参数。 serialize()
正在构建url编码的字符串,但是您需要键值对。试试这个:
$("#my_form").on("submit", function(event) {
event.preventDefault();
var myData = {id: getUrlParameter('id')};
for (var pair of formData.entries()) {
myData[pair[0]] = pair[1];
}
$.ajax({
url: 'saveJson.php',
type: 'POST',
data: myData,
dataType: 'json',
}).done(function(response) {
window.location = 'index.php';
});
});
}
