[英]Unable to send data to php from jquery ajax?
I am trying to send data to PHP using JQuery ajax. 我正在尝试使用JQuery ajax将数据发送到PHP。 However, I am only able to the send the first key=value
to PHP, the second key=value
echo as blank. 但是,我只能将第一个key=value
发送到PHP,第二个key=value
echo为空白。
For example: 例如:
functionName="+env works but not username="+username;
How can I pass multiple key value pair to PHP from JQuery AJAX? 如何从JQuery AJAX将多个键值对传递给PHP?
Jquery AJAX jQuery AJAX
var envdata="functionName="+env+",username="+username;
alert(envdata);
if(action == 'R'){
$.ajax({
type: "GET",
url: 'getdata.php',
data: envdata,
success: function(response) {
$("#textarea_message").val(response);
}
getdata.php 访问getdata.php
$env = filter_input(INPUT_GET, 'functionName');
echo $env
$username = filter_input(INPUT_GET, 'username');
echo $username;
You're building your data
wrong. 您建立的data
错误。 it's basically equivalent to a URL query string, which means you need to use &
as the separator, not a ,
: 它基本上等效于URL查询字符串,这意味着您需要使用&
作为分隔符,而不是,
:
var envdata="functionName="+env+"&username="+username;
^---note the &
commas mean nothing to PHP as far as url query arguments go, so your ,username=foo
would become part of the functionname
value. 就URL查询参数而言,逗号对PHP毫无意义,因此,您的,username=foo
将成为functionname
值的一部分。
A simple var_dump($_GET)
would show you exactly what PHP is seeing come in. Doing that should've been your first stop when you didn't get your expected data in the script. 一个简单的var_dump($_GET)
可以准确地告诉您PHP所见的内容。当您没有在脚本中获得期望的数据时,这样做应该是您的第一站。

$(document).ready(function() {
$('#some_button').on('click', function() {
var checks = new Array();
$("input[name='ls_id']:checked").each(function() {checks.push($(this).val());});
$.ajax({
type: 'POST',
url: "some url",
dataType: 'json',
cache: false,
data: {checks: checks, func: 9},
success: function(data) {
}
});
});
}); });
getdata: 的GetData:
$json = json_decode($_POST['checks'], true);
print_r ($json);
