使用jQuery AJAX将JSON对象传递到PHP文件 [英] Using jQuery AJAX to pass JSON Object to PHP file

问题描述

我有一个像这样的JSON对象(分配给 var card; ):

I have a JSON object like this (assigned to var card;):

{
    card_no: "1", 
    card_name: "wwwgdefonru",  
    img_id: 1, 
    img_thumb: "albums/070915_E239/thumbs/001_wwwgdefonru.jpg", 
    img_hires: "albums/070915_E239/thumbs_hires/001_wwwgdefonru.jpg"
}

我想使用AJAX将其传递给php支持文件.

I want to pass this using AJAX to a php support file.

这是我的AJAX电话:

Here's my AJAX call:

jQuery.ajax({
    method: 'POST',
    url: ajax_file,
    type: 'JSON',
    data:  card,
    dataType: 'html',
    cache: false,
    success: function(html){
        console.log('SUCCESSO');
        jQuery('#debug').html(html);    
    },
    complete:function(){
        console.log('COMPLETE');
    }
});

在我的PHP文件中(仅出于调试目的)，我输出传递的数据，如下所示:

In my PHP file (just for debugging purposes) I output the passed data like so:

echo '<pre>';
    print_r($_POST);
echo '</pre>';

AJAX调用成功完成.但是输出为空:

The AJAX call completes successfully. But the output is blank:

Array
(
)

我在哪里错了?

解决方案

我正在使用旧版本的jQuery进行项目(不要问...).通过查看文档( http://api.jquery.com/jquery.ajax/)我可以看到使用方法:'POST'设置方法无效，因为我所使用的JQ版本不支持该方法.将其切换为 type:'POST'并摆脱 type:'JSON'对其进行了修复.

I am working on a project with an old version of jQuery (don't ask...). From looking at the docs (http://api.jquery.com/jquery.ajax/) I could see that setting the method using method: 'POST' wasn't working because it isn't supported by the version of JQ I am using. Switching it to type: 'POST' and getting rid of type: 'JSON' fixed it.

即使我将其定义为 POST ，如果我没有查看网络"标签并看到请求方法为 GET ，我也不会发现这一点.

I wouldn't have spotted this had I not looked at the network tab and seen the request Method was GET even though I have defined it as POST.

推荐答案

编写发布这样的方法对您来说是如此简单

The method of writing post method is in this way is so easy for you

$.post("your_php_file_url.php",
    {
        card_no: "1", 
        card_name: "wwwgdefonru",  
        img_id: 1, 
        img_thumb: "albums/070915_E239/thumbs/001_wwwgdefonru.jpg", 
        img_hires: "albums/070915_E239/thumbs_hires/001_wwwgdefonru.jpg"
    },
    function(data, status){
        alert("Response Message" + data + "\nResponse Status: " + status);
    });

在您的PHP站点中，您使用读取值

In your PHP site you read the values using

<?php
     echo $_POST['card_no'];
?>

像这样，您可以获取其他值并完成工作！

like this you could get other values and do your works!
