Hi there!
i’m writing extender for ditto, to get options from treasure chest. the part of setting custom ditto placeholders is a bit confusing and i don’t get it at all.
if (!function_exists("tcPriceGetter")) {
function tcPriceGetter($resource) {
global $modx;
$productID = $resource["tcProductID"];
$table = $modx->getFullTableName('treasure_chest');
$query = "SELECT amount FROM $table WHERE id='$productID'";
$result = $modx->db->query($query);
$tcPrice = $modx->db->getValue($result);
$modx->setPlaceholder('tcquery', $query);
return ($tcPrice < 1) ? 'No price found' : $tcPrice;
}
}
if (!function_exists("tcOptGetter")) {
function tcOptGetter($resource) {
global $modx;
$productID = $resource["tcProductID"];
$table = $modx->getFullTableName('treasure_chest');
/* my own additions */
$options = "SELECT * FROM $table WHERE id='$productID'";
$options_query = $modx->db->query($options);
$product = $modx->db->getRow($options_query);
foreach ($product as $key => $value)
{
if ($value == null)
{
// Get rid of any NULL Values
unset($product[$key]);
}
}
return $product;
}
}
$placeholders['tcPrice'] = array(array("tcProductID","*"),"tcPriceGetter");
tcPriceGetter is function i took somewhere on these forums and it sets price in [+tcPrice+] right
what i need to do is to set several custom placeholders based on $product[$key]
but i don’t know how to set it right, all my experiments failed.
what’s is an asterisk in array(array("tcProductID","*"),"tcPriceGetter")?
tcProductIdD is a TV for every product document.
help please!
