现在我有这个表单:
<form name='steampaypalinfo' action='profile.php' method='post'>
PayPal Email: <br><input type='email' name='paypal'><br>
Steam Trade URL: <br><input type='text' name='tradeurl'><br><br>
<input type='submit' value='Update' name='submit'>
</form>
我在PHP中像这样检索数据:
if (isset($_POST['submit'])) {
if (empty($_POST['paypal'])) {
$paypalerror = "PayPal email is required!";
} else {
$paypalemail = $_POST['paypal'];
}
if (empty($_POST['tradeurl'])) {
$tradeurlerror = "Steam Trade URL is required!";
} else {
$tradeurl = $_POST['tradeurl'];
}
如您所见,我将表单数据(电子邮件和链接)存储到两个变量paypalemail和tradeurl中。
现在我想将这些数据添加到我已经制作的JSON文件中。JSON文件现在看起来是这样的:
{
"response": {
"players": [
{
"steamid": "76561198064105349",
"communityvisibilitystate": 3,
"profilestate": 1,

"timecreated": 1337817157,
"personastateflags": 0,

"locstatecode": "NY"
}
]
}
}
我想要的数据paypalemail和tradeurl数据进入球员数组。我读过关于使用file_put_contents或fwrite,但这些似乎都不起作用。
问题:如何将PayPal和Steam URL数据添加到已经制作的JSON文件中?我如何将该数据添加到JSON文件中已经制作的数据并正确格式化它?
谢谢你,任何帮助将是伟大的!
编辑我试过了:
$file = file_get_contents("cache/players/{$steam64}.json");
$json = json_decode($file, true);
$player_array['paypalemail'] = $paypalemail;
$json = json_encode($player_array);
$file = fopen("cache/players/{$steam64}.json", 'w');
fwrite($file, $json);
fclose($file);
它工作,但它覆盖JSON文件中的数据。我如何添加它而不覆盖它?
应该像这样:
$file = file_get_contents('players.json');
$json = json_decode($file, true); //second parameter, return as associative array
$player_array = &$json['response']['players'][0];
//lets setup new keys
$player_array['paypalemail'] = "johanroure@cool.com";
//whatever you want to add
$new_json = json_encode($json,JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES); //pretty and without slashes
$file = fopen('players.json', 'w'); //w set pointer to beginning and truncate to 0 :D
fwrite($file, $new_json);
fclose($file);
