[英]Ajax post to PHP not working
Hi i got a problem im doing a ajax post to a php file but in the php file its empty 嗨,我在将ajax发布到php文件时遇到了问题,但是在php文件中它为空
JS
google.maps.event.addListener(marker, 'click', function(marker, i) {
return function() {
var rid = locations[i][4]; //get id to varible
console.log(rid);
$.ajax({
url: uri+'/helper.php',
type: 'post',
data: {'referens': rid},
success: function(data){
console.log(rid);
window.location = uri+'/helper.php';
},error: function(data){
alert('error');
}
});
}
}(marker, i));
and my helper.php 和我的helper.php
<?php
$referens = $_POST['referens'];
echo $referens;
echo 1;
?>
the output in helper.php is only 1 and not my referens post helper.php中的输出仅为1,而不是我的referens post
what if i want to use it like this in same file with location.reload(); 如果我想在具有location.reload()的同一文件中使用这种方式怎么办?
success: function(data){
console.log(data);
location.reload();
},error: function(data){
alert('error');
}
});
}
}(marker, i));
</script>
<?php include_once('helper.php');
var_dump($referens); ?>
and helper.php 和helper.php
<?php
$referens = $_REQUEST['referens'];
echo $referens;
echo 1;
?>
Your code looks fine. 您的代码看起来不错。
You are printing the wrong variable. 您正在打印错误的变量。
Change 更改
success: function(data){
console.log(rid);
window.location = uri+'/helper.php';
}
To 至
success: function(data){
console.log(data); // Here you are getting return in data not as rid
window.location = uri+'/helper.php?rid='+rid; // See, pass rid here.
}
in helper.php 在helper.php中
<?php
$referens = $_REQUEST['referens'];
echo $referens;
echo 1;
?>
As per your comments on other answers and on your post, I would like to mention this: 根据您对其他答案和您的帖子的评论,我想提一下:
console.log(rid);
window.location = uri+'/helper.php';
In your success callback rid
is 91
as it should be as per your comments and that is absolutely correct because at the php
file you are trying to access a POST
var. 在您的成功回调中
rid
是91
因为它应该按照您的注释,这是绝对正确的,因为在php
文件中,您尝试访问POST
变量。
But when this line executes window.location = uri+'/helper.php';
但是当这一行执行
window.location = uri+'/helper.php';
then location changes and it makes a GET
request, so it fails. 然后位置发生变化并发出
GET
请求,因此失败。
To get this var at PHP
end you should try with $_REQUEST('referens')
and you have to send it with url like this: 要在
PHP
端获取此var,应尝试使用$_REQUEST('referens')
并且必须使用以下网址发送它:
window.location = uri+'/helper.php?referens=' + rid;
and at your php end: 并在您的PHP端:
<?php
$referens = $_REQUEST['referens']; // <---change here.
echo $referens;
echo 1;
?>
From the docs [ $_REQUEST()
]: 从文档[
$_REQUEST()
]:
An associative array that by default contains the contents of $_GET, $_POST
and $_COOKIE
. 关联数组,默认情况下包含
$_GET, $_POST
和$_COOKIE
。
