Create array in php and use Jquery get - php

Question

I'm trying to make a call to the database and recieve a "toplist" that is limited to 10 in PHP. Here I need to make an array and give it back to the Jquery with $.get().
But it's failing in recieving all the data with this code, How can I make this to be recieved and then do a "for each" in the Jquery for all the data that is being sent back from the PHP?
Jquery:
$.get("core.inc.php?get_toplist=1",
function(data) {
var json = JSON.parse(data);
alert(json['name']);
});
PHP:
if ($_GET['get_toplist']) {
$get_top_list = mysql_query("
SELECT * FROM ".$DBprefix."Submissions
WHERE status='1'
ORDER BY points DESC LIMIT 10");
$i = 0;
$arr = array();
while ($top_list = mysql_fetch_array($get_top_list)) {
$arr[] = array(
'position' => $i++,
'name' => $top_list['name'],
'points' => $top_list['points']
);
}
echo json_encode($arr);
}

Answer 1

You're returning an array, but your Javascript code is treating it as a single element. Try:
alert(json[0].name);
If you want a foreach, you can do:
$.each(json, function(i, el) {
console.log(el.name + " score is " + el.points);
});

Answer 2

Friend your json will be like .
[{"position":1,"name":"name1","points":"points"},{"position":2,"name":"name2","points":"points"}, {"position":3,"name":"name3","points":"points"},....]
so you can not directly access it like ur way.
make a loop then access it.
$.each(data,function(i,val){
alert(val.name);
});
this will work.

your php code is not proper
if ($_GET['get_toplist']) {
$get_top_list = mysql_query("
SELECT * FROM ".$DBprefix."Submissions
WHERE status='1'
ORDER BY points DESC LIMIT 10");
$i = 0;
$arr = array();
while ($top_list = mysql_fetch_array($get_top_list)) {
$arr[] = array(
'position' => $i++,
'name' => $top_list['name'],
'points' => $top_list['points']
);
}
}
echo json_encode($arr);
}
just add '}' before echo json_encode($arr);
also you are getting an array change in alert(json[0]['name']);
