Processing data from an AJAX request
- by Josh K
I have a PHP API I'm working with that outputs everything as JSON.
I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter).
When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request.
Simplified code:
$.ajax
({
type: "POST",
url: "http://mydomain.com/api/get/userlist/"+mid,
dataType: "json",
dataFilter: function(data, type)
{
/* Here we assume and pray */
users = eval(data);
alert(users[1].id);
},
success: function(data, textStatus, XMLHttpRequest)
{
alert(data.length); // Should be an array, yet is undefined.
},
error: function(XMLHttpRequest, textStatus, errorThrown)
{
alert(textStatus);
alert(errorThrown);
},
complete: function(XMLHttpRequest, textStatus)
{
alert("Done");
}
});
If I leave off the eval(data) then everything works fine. Well, except for data still being undefined in success. Note that I'm taking an array of objects in PHP and then passing them out through json_encode. Would that make any difference?
There has been no progress made on this. I'm willing to throw more code up if someone believes they can help.
Here is the PHP side of things
private function _get_user_colors($id)
{
$u = new User();
$u->get_where(array('id' => $id));
$bar = array();
$bar['user'] = $u->stored;
foreach($user->colors as $color)
{
$bar['colors'][] = $color;
}
echo(json_encode($bar));
}
I have had zero issues using this with other PHP based scripts. I don't know why Javascript would take issue with it.
