我通过AJAX将表单数据作为JSON传递给PHP文件，然后将JSON保存在服务器上的文本文件中。FILE_APPEND与file_put_contents无法正常工作
问题是，当我使用FILE_APPEND时，数据不会写入文件中，当JSON数据已经存在于文本文件中时。
我的HTML代码：
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="eloqua.css">
<script src="http://code.jquery.com/jquery-1.9.0.js"></script>
<script type="text/javascript">
$(document).ready(function(){
localStorage.clear();
$("form").on("submit", function() {
if(window.localStorage!==undefined) {
var fields = $(this).serialize();
localStorage.setItem("eloqua-fields", JSON.stringify(fields));
alert("Stored Succesfully");
$(this).find("input[type=text]").val("");
alert("Now Passing stored data to Server through AJAX jQuery");
$.ajax({
type: "POST",
url: "backend.php",
data: fields
});
} else {
alert("Storage Failed. Try refreshing");
}
});
});
</script>
<script type="text/javascript">
function validateForm()
{
var a=document.forms["EloquaForm"]["C_FirstName"].value;
if (a==null || a=="")
{
alert("First name must be filled out");
return false;
}
var b=document.forms["EloquaForm"]["C_LastName"].value;
if (b==null || b=="")
{
alert("Last name must be filled out");
return false;
}
var y=document.forms["EloquaForm"]["C_EmailAddress"].value;
var atpos=y.indexOf("@");
var dotpos=y.lastIndexOf(".");
if (atpos<1 || dotpos<atpos+2 || dotpos+2>=y.length)
{
alert("Not a valid e-mail address");
return false;
}
}
</script>

和我的PHP代码：
<?php
date_default_timezone_set('America/Chicago'); // CDT
echo '<h2>Server Timezone : ' . date_default_timezone_get() . '</h2>';
$current_date = date('d/m/Y == H:i:s ');
print "<h2>Server Time : " . $current_date . "</h2>";
$dataObject = $_POST; //Fetching all posts
echo "<pre>"; //making the dump look nice in html.
var_dump($dataObject);
echo "</pre>";
//Writes it as json to the file, you can transform it any way you want
$json = json_encode($dataObject);
file_put_contents('your_data.txt', $json . PHP_EOL, FILE_APPEND);
?>
这没有任何意义，'file_put_contents（）'不会对您的文件进行重复扫描。函数返回什么？ – jeroen
你做过任何调试，比如检查f_g_c（）的返回值吗？完成'is_writable（'your_data.txt'）'测试？另外，除非你想通过换行符分割文件，并且希望编码数据中没有换行符，否则不能合并单个json编码的字符串。 –
@MarcB - 该文件是可写的，因为我可以在这里看到一些数据：http://hackingarticles.com/marketer/your_data.txt另外，我希望在每次提交后都有换行符。任何关于代码更改的建议？ –
