[英]Send $_POST array using ajax with PHP?
I have multiple input fields with the name Change[xxx]
. 我有多个输入字段,名称为
Change[xxx]
。 The original way is when an update button is clicked, it normally sends the data and updates the database. 原始方式是单击更新按钮时,通常会发送数据并更新数据库。 But how do I pass this
Change[xxx]
data if I use Ajax? 但是,如果我使用Ajax,如何传递
Change[xxx]
数据? I want to do this without jQuery. 我想在没有 jQuery的情况下执行此操作。
The HTML: HTML:
<input type='text' name='Change[name]' value='Bob' onblur='updateField($id)'></input>
Retrieving the info in PHP: 检索PHP中的信息:
foreach($_POST['Change'] as $field => $value) {
if($field == 'name') {
// update database
}
}
The JavaScript: JavaScript:
Using request.send(...)
, this is where I'm not sure how to send the data. 使用
request.send(...)
,这是我不确定如何发送数据的地方。
function updateField(id) {
…
var url = 'orders.php?id='+ id;
request.open('POST', url, true);
request.setRequestHeader("Content-type","application/x-www-form-urlencoded");
var val = document.getElementsByName("Change[name]")[0].value;
request.send("id=" + id + "&Change[" + val + "]");
…
}
Exactly the same as you usually would: 与通常的情况完全相同:
request.send("id=" + id + "&Change[name]=" + encodeURIComponent(val));
The brackets aren't special to HTTP, only to PHP. 括号不是HTTP专用的,只是PHP专用的。
