使用AJAX将数组和字符串从Javascript传递到PHP

Question

I have the following ajax call.

My addList variable holds a string: list=Sports&list=Cars&list=Outdoor&new_list=123123

I want to grab the addList in my PHP file as

$_POST['list'] is an array with values Sports, Cars, Outdoor
$_POST['new_list'] is a string 123123

But I couldnt convert the POST string into right forms.

I can create arrays/loops in both sides but it didnt feel right.

Whats the convenient way of doing it?

jQuery.ajax({  
                    type: "post",  
                    url: ajax_var.url,  
                    data: "action=post-list&nonce="+ajax_var.nonce+"&post_list=&post_id="+post_id+"&" + addList,  
                    success: function(count){  
                        alert("done"); 
                    }  
                }); 

Any help will be appreciated. thanks!

Answer 1

try using followig code.

you just neeed to locate your form if and url to pass values to :

var form = new FormData($('#form_id')[0]);
form.append('view_type','addtemplate');
$.ajax({
type: "POST",
url: "savedata.php",
data: form,
cache: false,
contentType: false,
processData: false,
success:  function(data){
//alert("---"+data);
alert("Settings has been updated successfully.");
window.location.reload(true);
}
});

this will pass all form element automatically.

Working and tested code.

When you pass variable with the ajax method from jQuery, you can pass array like this :

jQuery

    var myArray = newArray();
    myArray.push("data1");
    myString = "data2";


    jQuery.ajax({  
         type: "post",  
         url: ajax_var.url,  
         data: {array:myArray, param2:myString},
                  ^name     ^value
         success: function(count){  
             alert("done"); 
         }  
    }); 

PHP

echo $_POST['array'][0]; // data1
echo $_POST['param2']; // data2

Change your addList variable to this:

list[]=Sports&list[]=Cars&list[]=Outdoor&new_list=123123

PHP will parse the items named list[] into an array, and you'll find the values as $_POST['list'][0] , $_POST['list'][1] , $_POST['list'][2]
