JQuery autocomplete with remote JSON datasource not working - php

Question

I'm using this jquery plugin : JQuery Autocomplete. Problem I'm getting json data but it's not appearing on the autocomplete list.
The JQuery code:
$( "#student-id" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "ajax/ajax_admin.php?auto_student=" + $( "#student-id" ).val(),
dataType:"json",
data: {
featureClass: "P",
style: "full",
maxRows: 12,
name_startsWith: request.term
},
success: function( data ) {
response( $.map( data.students, function( item ) {
return {
label: item.id +" , "+ item.name,
value: item.id
}
}));
}
});
},
minLength: 2,
open: function() {
$( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
},
close: function() {
$( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
}
});
The PHP Script is :
public function load_ajax_student_list($val)
{
$val = "%".$val."%";
$stmt = $this->conn->prepare("select * from student where studentAiubId like :value limit 0,5");
$stmt->bindValue(':value', $val);
$stmt->execute();
if($stmt->rowCount() < 1)
echo "";
else
{
$result = $stmt->fetchAll();
$output = array();
foreach($result as $row)
{
if($row['mname']=="")
$name = $row['fname']." ".$row['lname'];
else
$name = $row['fname']." ".$row['mname']." ".$row['lname'];
$data["name"] = $name;
$data["id"] = $row['studentAiubId'];
$output["students"][] = $data;
}
echo json_encode($output);
}
}
If the call goes like this: ajax/ajax_admin.php?auto_student=10
The produced data from PHP script is :
{
"students": [
{"name":"Moh Mamun Sardar","id":"10-15987-1"},
{"name":"Rehan Ahmed","id":"10-12451-2"},
{"name":"Abid Hassan","id":"10-15412-1"},
{"name":"Abir Islam","id":"10-11245-1"}
]
}
But Nothing showing on autocomplete. What I'm doing wrong?

Answer 1

try something like this
$.map( data.students, function(item ) {
return {
label: item.name,
value: item.id
});
it is minlength not minLength see casing

Answer 2

You have forgotten the "appendTo" property. In this propery you have to specify the selector of the element you wish the information to be appended to like this
appendTo: '.class' or appendTo: '#id'
You have to add this property to the initialization of the autocomplete as a sibling of source and etc ...
