[英]AJAX call success but throws Undefined index error
I have an ajax call that passes data to another php file, createTest2.php, as below. 我有一个ajax调用,它将数据传递到另一个PHP文件createTest2.php,如下所示。
But the createTest2.php file throws error 但是createTest2.php文件抛出错误
"Notice: Undefined index: aaa in C:\\xampp\\htdocs\\TestProj\\Test\\createTest2.php on line 2 “注意:未定义的索引:第2行的C:\\ xampp \\ htdocs \\ TestProj \\ Test \\ createTest2.php中的aaa
caller.php caller.php
$(document).ready(function(){
$("#button_submit").click(function()
{
$.ajax({
type:"POST",
url:"createTest2.php",
data:{aaa : "UNIT_TEST"},
success:function()
{
alert("success");
}
});
});
});
createTest2.php createTest2.php
$test_name = $_POST['aaa'];
there is nothing wrong on your code/script. 您的代码/脚本没有错。 i tried it on my localhost and it works.
我在我的本地主机上尝试过,它可以工作。
make sure that the error reporting is configured correctly because it is printing a notice that will also be passed to your ajax result. 确保错误报告配置正确,因为它正在打印一条通知,该通知也将传递给您的ajax结果。
to remove it use these on top of php code of your createTest2.php
: (before you call anything, just after the first php opening tag) 要删除它,请在
createTest2.php
的php代码之上使用这些代码(在调用任何内容之前,在第一个php开头标记之后)
<?php
ini_set("DISPLAY_ERRORS",0);
error_reporting(0);
take note that it is only a NOTICE
and not an ERROR
as indicated on your question. 请注意,它只是一个
NOTICE
而不是您的问题所指示的ERROR
。 hope that helps. 希望能有所帮助。 ;)

** UPDATE: some people say it is recommended to fix the notices instead of just hiding them, just so you know.. **更新:有人说,建议您修正通知,而不是仅仅隐藏它们,这就是您所知道的。
Give data attribute in quotes, 给数据属性加引号,
Change 更改
data:{aaa : "UNIT_TEST"},
To 至
data:{"aaa" : "UNIT_TEST"},
try to send is as an data query ( using param to convert object to an data query) 尝试以数据查询的形式发送(使用param将对象转换为数据查询)
$(document).ready(function(){
$("#button_submit").click(function()
{
var params = $.param({aaa : "UNIT_TEST"});
$.ajax({
type:"POST",
url:"createTest2.php",
data: params,
success:function()
{
alert("success");
}
});
});
});
