I wrote out this code, but have noticed if I try to print orders that
are plus 1000~ I get a large hang in the program, can someone offer
some help in optimizing it?
[code=php]
case “Ordination Credentials”:
$q = “SELECT o.date_purchased, fd.template_fn, o.customers_name, op.orders_id, opa.orders_products_id, products_name, op.products_quantity, field_name, products_options_values
FROM orders_products AS op
join orders as o on o.orders_id = op.orders_id
JOIN fulfillment_doc_products AS fdp ON fdp.product_id = op.products_id
JOIN fulfillment_docs AS fd ON fd.doc_id = fdp.doc_id
JOIN orders_products_attributes AS opa ON opa.orders_products_id = op.orders_products_id
right JOIN fulfillment_doc_fields AS fdf ON fdf.products_options_name = opa.products_options
AND fdf.doc_products_id = fdp.doc_products_id
WHERE op.orders_id
BETWEEN $in
AND $out
AND fd.doc_id = $doc_id
ORDER BY o.orders_id, products_name, opa.orders_products_id, field_name, products_options_values”;
$r = mysql_query($q) or die(mysql_error());
while($row = mysql_fetch_array($r)) {
//Template Filename is managed on admin front end
$template_fn = getcwd().’/templates/’ . $row[‘template_fn’];
//Standard db output filtering and processing into multi-dimensional array as seen above
$datas[$row[‘orders_products_id’]][$row[‘field_name’]] = sanitize_db_output($row[‘products_options_values’]);
$datas[$row[‘orders_products_id’]][‘order_number’] = $row[‘orders_id’];
$datas[$row[‘orders_products_id’]][‘products_quantity’] = $row[‘products_quantity’];
}
