将数组从Javascript发布到PHP

Question

I have an array in Javascript that i am trying to pass to php. my array looks like this.

 Array[0]
   "empNo" : "1347"
   "empName" : "John Doe"  

I am building this array from this javascript:

$('input[type=text]').each(function()
{
             if ($(this).attr("value").length>0)
             {
                  param[$(this).attr("id")]=$(this).attr("value");
             }            
});

Then I pass the array to php using

$.post("example.php",param)

Then in php when I try to interact with the post like this:

$emp=$_POST['empNo'];
$name=$_POST['empName'];
echo ($_GET[0]);//this is for testing 

It throws an error saying that The Indexes of empNo and empName are not Defined.

It also says that 0 is an undefined offset.
Thanks for the help

Instead of looping through and manually building your data to pass just do this for the whole form.

var data = $('form').serialize();

$.post("example.php", data);

Then you should have access as you expect in your php script.

BUT make sure you're using the <input name="exampleName" /> attribute and then try to access them like this...

$value = $_POST['exampleName'];

while right now, it looks like you're trying to use the id instead of name
