Question

我正在尝试通过AJAX POST将大量数据集传递给PHP。我的数据被截断了，但我看不出原因。

var greeting     = tinyMCE.get("greeting").getContent();
...
var content = "subject="          +subject+
              "&greeting="        +greeting+
              "&results="         +results+
              "&upcoming="        +upcoming+
              "&thisweek="        +thisweek+
              "&signoff="         +signoff;

console.log(content);   //<--see below for this output
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", "scripts/send_email.php", true);
xmlhttp.setRequestHeader("content-type", "application/x-www-form-urlencoded");
xmlhttp.send(content);

send_email.php

$greeting       = $_POST['greeting'];
echo $greeting;
die();

这是我的内容变量的控制台输出（请注意，在您看到格式的地方，控制台会输出HTML标记，但我不知道如何在此处显示标记。）

> subject=test&greeting=<p class="p1"><strong>Hello all,</strong></p> <p
> class="p2">&nbsp;</p> <p class="p1">&nbsp;</p> <p class="p3">This is a

> /></p>&thisweek=<p><strong><span style="text-decoration:
> underline;">THIS WEEK</span></strong><br /><br /><br
> /></p>&signoff=<p>See you out there.</p>"

但是，我的php echo语句仅输出：

Hello all,

这显然会截断我试图传递的其余数据。为什么？我究竟做错了什么？谢谢！

Answer 1

您需要对数据进行编码，并将其放入参数

var content = "subject=" + encodeURIComponent(subject) +

等

Answer 2

您发送的内容类型为“... url-encoded”，同时发送的数据不是网址编码的。您需要在发送数据之前正确编码数据（encodeURIComponent等）

Answer 3

你只是回应你的问候。

试试这个：

echo  implode($_POST);
