$data;
$res;
if (empty($ret)) {
$res = 0;
$data = 0; // Partner server slow.
curl_close($ch);
} else {

if (empty($info['http_code'])) {
$res = 01;
$data = 01; // Got empty date from partner server
} else {
if ($this->errorType($info['http_code']) == TRUE) { // errors type

}
This is a function to check to know what type of server errors respond Purpose I want to checking when my partner server errors and I will send this kind of errors to my website for make sure what kind of errors.
private function errorType($haystack) {
$errors = array(404, 200, 201, 204, 500, 501, 502, 503, 504, 505, 100, 203);
if (in_array($haystack, $errors)) {
return $haystack;
} else {
return FALSE;
}
}
Here is Jquery Ajax to fetch data from my own server
$.ajax({
method: "GET",
url: "<?PHP echo base_url('getcurrentday'); ?>",
dataType: "JSON",
beforeSend: function (xhr) {
},
success: function (data, textStatus, jqXHR) {
$(".loading").html("");
if (data.res !== 200) {
$("<p>Errors type:"+data.res+"</p>").appendTo(".errors");
} else {
if (data.data == false) {
getdata();// I want to reload Ajax if I got respond false and my data = '';
}
$.each(eval(ldata), function (i, val) {
$(val.anydata").appendTo(".result");
})
}
}
});
Please help.

It seems that your ajax call gets a timeout and therefor it is not always working. You can increase the timeout setting of ajax.
Furthermore you can add an error function to see when errors like timeouts occur.
$.ajax({
//your ajax code here...
error: function(jqXHR, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
},
timeout: 10000 // sets timeout to 10 seconds
});
The reason you still see the response in firebug is that the browser will anyways receive the server response, even on timeout, but it will not reach your jquery code.
