Question
题
I am trying to create a form that will allow my users to add entries to the site. Entries are stored in a JSON file. I have created a form that submits to the JSON form and is formatted like this:
我正在尝试创建一个表单，允许我的用户向站点添加条目。条目存储在 JSON 文件中。我创建了一个提交到 JSON 表单的表单，其格式如下：
{"startDate":"example",
"headline":"example",
"text":"example",
"media":"example",
"caption":"example"}
Media and caption relate to an image, video or other multimedia, i need them to be stored as a separate object like the example below.
媒体和标题与图像、视频或其他多媒体有关，我需要将它们存储为单独的对象，如下例所示。
{"startDate":"example",
"headline":"example",
"text":"example",
"asset" :{"media":"example",
"caption":"example"}
}

<?php
// check if a form was submitted
if( !empty( $_POST ) ){
// convert form data to json format
$postArray = array(
"startDate" => $_POST['startDate'],
"headline" => $_POST['headline'],
"text" => $_POST['text'],
"asset" => array(
"media" => $_POST["media"],
"caption" => $_POST['caption']
)
); //you might need to process any other post fields you have..
$json = json_encode( $postArray );
// make sure there were no problems
//if( json_last_error() != JSON_ERROR_NONE ){
//exit; // do your error handling here instead of exiting
// }
$file = 'entries.json';
// write to file
// note: _server_ path, NOT "web address (url)"!
file_put_contents( $file, $json, FILE_APPEND);
}

You know json_encode? Simply pass an assisiative array to this function with the given structure
你知道json_encode吗？只需将具有给定结构的辅助数组传递给此函数
Create an new array i.e and pass it to json_encode
创建一个新数组 ie 并将其传递给 json_encode
$array = array(
"startDate" => $_POST['startDate'],
//..
"assets" => array(
"media" => $_POST["media"]
//..
)
);
$json = json_encode($array);
