情况:
对于每位客户,进行购买,从卖家中减去库存,向卖家帐户添加资金。
// for each customer
for ($c = 1; $c <= $maxCustomers; $c++) {
// decide what to buy
$willBuy = rand('1','7');
// buy indica
if ($willBuy == '1') {
// how many eights are they going to buy..
$willSpend = rand('1', '4');
if ($indicaPrice < $averageIndicaPrice) {
if ($indicaAvailable > $willSpend) {
// update products
$newIndica = $indicaAvailable - $willSpend;
update_user_meta($sellerID, 'Indica', $newIndica);
// pay for purchase
$newCash = $cash + $indicaPrice;
update_user_meta($sellerID, 'cashOnHand', $newCash);
echo "<tr>";
echo "<td>#".$c."</td>";
if ($willSpend > "1") { echo "<td>".$willSpend." 8th's of Indica Flowers</td>"; }
else { echo "<td>".$willSpend." 8th of Indica Flowers</td>"; }
echo "<td>$".$indicaPrice * $willSpend."</td>";
echo "</tr>";
}
else {
echo "<tr>";
echo "<td>#".$c."</td>";
echo "<td>Could not find anything they liked. No sale.</td>";
echo "<td>$0</td>";
echo "</tr>";
}
}
}
}
问题#1:在“更新产品”部分,它仅更新1个循环结果。如果有多个客户购买'indica',它只更新1个结果的indica meta值,而不是每个结果更新(即,如果2个人每个购买3个标记,则只减去3个标记而不是6个)。
问题#2:同样的事情发生在“购买付款”部分。它只更新一次购买的现金,而不是每次购买。
答案 0 :(得分:0)
你永远不会改变$indicaAvailable
你呢?你不应该根据售出的东西更新吗?
