Assigning PHP variable to PHP array
Question
I want to assign some php to a javascript variable like:
var goldPrice = <?php echo ResourceArray::$goldLevel[$user->getResource($data->id, "goldLevel")]?>;
but ends up with: 1 (instead of 2000).
Here's my troubleshooting:
I have an array in a php class:
<?php
class ResourceArray {
public static $goldLevel = array(
0, 2000, 10000
),
I've tried to assign through a couple of variables to find the problem with no luck:
var goldLevel = <?php $user->getResource($data -> id, "goldLevel") ?>;
var goldPrice = <?php echo ResourceArray::$goldLevel[$user->getResource($data->id, "goldLevel")]?>;
var goldPrice1 = <?php echo ResourceArray::$goldLevel[1]?>;
This writes:
var goldLevel = 1;
var goldPrice = 1;
var goldPrice1 = 2000;
Finally I tried to assign a php variable to put in:
PHP: $goldLevel1 = $user->getResource($data->id, "goldLevel");
$goldLevel2 = 1;
js: var goldPrice2 = <?php echo ResourceArray::$goldLevel[$goldLevel1]?>;
var goldPrice3 = <?php echo ResourceArray::$goldLevel[$goldLevel2]?>;
This ends up like:
var goldPrice2 = ;
var goldPrice3 = 2000;
When I echo $goldLevel1 and $goldLevel2, it shows 1 and 1.

Trying this works fine with me:
<html><body>
<?php
class ResourceArray {
public static $goldLevel = array(
0, 2000, 10000
);
}
// set gold price to second entry of goldLevel array
$goldPrice = ResourceArray::$goldLevel[1];
// check to make sure we have a valid number
if (!is_numeric($goldPrice) || $goldPrice < 1)
$goldPrice = 0;
// this outputs 2000
echo $goldPrice;
?>
<script>
var goldPrice = <?php echo $goldPrice; ?>;
alert(goldPrice);
</script>
</body></html>

Try using json_encode()
Use it like this
var goldPrice = <?php echo json_encode(array(0, 2000, 10000))?>;
Just replace the array for the dynamically created one.

First of all create a variable of json
var jsonO = <?php echo json_encode(array(0, 2000, 10000))?>;
this will be a json string, convert it to javascript array
var goldPrice = $.map(jsonO, function(el) { return el; })
then use goldPrice array.
