我将表单数据作为JSON通过AJAX传递给PHP文件，然后将JSON保存在服务器上的文本文件中。
问题在于，当我使用FILE_APPEND时，当文本文件中已存在JSON数据时，数据不会写入文件。
我的HTML代码是：
<!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>
</head>

我的PHP代码是：
<?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);
?>
答案 0 :(得分：1)
如果我理解（在看到hackingarticles.com/marketer/your_data.txt之后）。你的代码看起来很有效。尝试更改为：
$file_content = array();
if ( file_exists('your_data.txt')){
$file_content = (array)json_decode(file_get_contents('your_data.txt'));
unlink('your_data.txt');
}
$file_content['users'][] = array('user'=>$_POST);
file_put_contents('your_data.txt',json_encode($file_content));
