Send an array and a single string to a PHP script using an Ajax request

I am attempting to incorporate the code snippet below:

 var flag = new Array();
 var name = $("#myselectedset").val();      
$.ajax({
    type:         'post',
    cache:         false,
    url:          'moveto.php',
    data:     {'myselectset' : name,
              'my_flag' : flag
              },
    success: function(msg){
                     $("#statusafter").ajaxComplete(function(){$(this).fadeIn("slow").html(msg)});
                      }     
          });

As you can see, "name" is a single string and "flag" is an array. I'm unsure if I am using the correct format for passing them through the ajax call. Any assistance would be greatly appreciated. Thank you.

Answer №1

When sending a POST request, arrays cannot be directly passed. Only strings are accepted.

To work around this limitation, you have two options: either stringify your array before sending the request, or send the data as JSON instead.

If you want to easily replace the "data" property, try this simple solution:

data : JSON.stringify( { myselectset : name, my_flag : flag } )

This code will convert the data into a JSON string for easy manipulation in PHP on the receiving end by using json_decode($_POST["my_flag"]);

It is crucial to note:

In order for JSON.stringify to function properly, there should not be any functions within the array - not even object methods that are functions.

Furthermore, since this is just a brief example, remember to handle cases of null data and adhere to other best practices during testing.
