In Javascript, get value of multidimensional array WordPress

John Buchmann comments:

That works in your specific example. That's progress! :) But my PHP array is more specifically built like this:


<begin loop>

$array_mapinfo = array($counter=>array(0 =>'United States', 1=>'700 Trapp Hill Rd', 2=>'Stowe, Vermont', 3=>'http://www.sample.com/image.png', 4=>'350,000', 5=>'http://www.sample.com'));

$counter=$counter + 1;

<end loop>



If I hard code $counter to be a number, then it works, but I need it to be a variable that increments in a loop. When I do this it doesn't work.

Maor Barazany comments:

What is the value of your array after the loop?
Paste here please var_dump($array_mapinfo) after the loop.
Paste the loop also.
It might be that you are overriding the array in each iteration.
Try
$array_mapinfo[] =
to add to the array and not overriding it.

Try this loop for example:


for ($i=0;$i<4;$i++) {
$array_mapinfo[$i] =
array(
0 =>$i.'-United States',
1=>$i.'-700 Trapp Hill Rd',
2=>$i.'-Stowe, Vermont',
3=>$i.'-http://www.sample.com/image.png',
4=>$i.'-350,000',
5=>$i.'-http://www.sample.com'
)
;
}

?>
<script type="text/javascript">

var jsArray = <?php echo json_encode($array_mapinfo); ?>;
alert(jsArray[2][2]);
</script>

Of course, the $i that appears inside the inner array was just for the test of the alert to see it's alerting the right value, you don't really need it in there...
Here's the code without it..


for ($i=0;$i<4;$i++) {
$array_mapinfo[$i] =
array(
0 =>'United States',
1=>'700 Trapp Hill Rd',
2=>'Stowe, Vermont',
3=>'http://www.sample.com/image.png',
4=>'350,000',
5=>'http://www.sample.com'
);
}

That was it, thanks! I needed to put the $counter part on the main array variable, like this:



$array_mapinfo[$counter] =

array(

0 =>'United States',

1=>'700 Trapp Hill Rd',

2=>'Stowe, Vermont',

3=>'http://www.sample.com/image.png',

4=>'350,000',

5=>'http://www.sample.com'

);



So my PHP array was having the wrong syntax. Thanks so much! :)
