通过jQuery的Ajax通过PHP数组 [英] Pass PHP Array via jQuery Ajax

问题描述

我有一个PHP数组：

$toField = explode(",", $ids);  //Which looks something like '24,25,26,29'

我想通过通过jQuery AJAX这个数组，这一点：

I want to pass this array via jQuery AJAX, with this:

<form id="myForm">
  <input type="hidden"  value="'.$toField.'">
  <input type="submit" id="sendMessage" class="faceboxSubmit" name="ok" value="Send Reply"/>
</form>

这是我的jQuery的：

And here's my jQuery:

$("#sendMessage").click(function(event){
	event.preventDefault();
	var senderID = <?php echo $usrID; ?>;
	var receiverID = $("#toField").val();
	$.ajax( 
{ 
    type: "POST", 
    url: "replyMessage.php", 
    data: "senderID=" + senderID + "&subject=" + subject + "&message=" + message + "&receiverID=" + receiverID + "&threadID=" + thread_id,
	beforeSend: function() {
		$("#sendingMessage").show();
		},
            success: function() {
		alert("Success");
		}

         });    
	});

我

如何传递数组，使之与replyMessage.php页面中，我可以把每个ID从阵列，做这样的事情：

How can I pass the array, so that with the "replyMessage.php" page, I could take each ID from the Array, to do something like this:

    <?php 

    foreach ($_POST['receiverID'] as $receiverID) 
   { 
     mysql_query //etc...
   }

任何帮助是极大AP preciated！

Any help is greatly appreciated!

推荐答案

首先，你可能想使用 爆 ，而不是爆炸，来构建你的 $ toField 变量; - ）

First, you probably want to use implode, and not explode, to construct your $toField variable ;-)

$ids = array(24, 25, 26, 29);
$toField = implode(',', $ids);
var_dump($toField);

这将使你

string '24,25,26,29' (length=11)

您在随后的形式注入这一点;这样的事情可能会做：

You then inject this in the form ; something like this would probably do :

<input type="hidden"  value="<?php echo $toField; ?>">

的（再检查一下你的表单的HTML源代码，以确保;-)）的

结果
然后，当它被提交从表单接收数据的PHP脚本，你会使用 爆炸 来提取数据作为一个数组，从字符串：

Then, on the PHP script that receives the data from the form when it's been submitted, you'd use explode to extract the data as an array, from the string :

foreach (explode(',', $_POST['receiverID']) as $receiverID) {
    var_dump($receiverID);
}

这将让你：

string '24' (length=2)
string '25' (length=2)
string '26' (length=2)
string '29' (length=2)

和，现在，你可以使用IDS放入系统...

And, now, you can use thoses ids...
