AJAX请求在PHP中给出了“未定义的索引”错误

Question

I'm getting undefined index(return data) from this AJAX call. What am I doing wrong here? Please correct me.

$(document).ready(function() {
    $('#something').click(function() {
        edit(1, 'abc', 'xyz');
    });

    function edit(id, column, text) {
        $.ajax({  
            url: "edit.php",  
            method: "POST",  
            data: {
                id: id, 
                text: text, 
                column: column
            },  
            dataType: "text",  
            success: function(data) {  
                 console.log(data);  
            }  
        });      
    }
});

edit.php

echo $_POST["id"];

I'm getting this in the console:

Notice: Undefined index: id in C:\xampp\htdocs\datatable\edit.php on line 2

I think the problem is because of the way you wrote the json array keys.

Try to use double quotes for the keys from data json, like this:

data:{"id":id, "text":text, "column":column}

or use different names for variables and keys.
