只卸載特定類型的數據庫

Question

的出現導致啓動文件的循環：

<?php 

$result_for_base_a = $this->db->query("SELECT * FROM oc_order_option WHERE order_id = '$id'"); 
for($j = 0; $j<count($result_for_base_a->rows); $j++) { 
    $product_option_value_id = $result_for_base_a->rows[$j]['product_option_value_id']; 
    $product_option_id = $result_for_base_a->rows[$j]['product_option_id']; 

    $result_for_base_c = $this->db->query("SELECT * FROM oc_product_option WHERE product_option_id = '$product_option_id'"); 
    $product_id = $result_for_base_c->row['product_id']; 
    $result_for_base_b = $this->db->query("SELECT * FROM oc_product_option_value WHERE product_option_value_id = '$product_option_value_id' AND product_id='$product_id'"); 
    $points = $result_for_base_b->row['points']; 

    $price = $result_for_base_b->row['price']; 
    $counts = $result_for_base_a->rows[$j]['quantity']; 
} 

我需要補充，會爲只有那些選擇選項，創建可啓動數據的規則。

表有「型」，還有一個選擇，多選，電臺，圖像等，但我需要循環忽略所有類型，除了選擇。

你只需要添加條件type = 'select'到你的選擇。試試這樣的：

<?php 

$result_for_base_a = $this->db->query("SELECT * FROM oc_order_option 
    WHERE order_id = '$id' AND `type` = 'select'"); 

for($j = 0; $j<count($result_for_base_a->rows); $j++) { 
    $product_option_value_id = $result_for_base_a->rows[$j]['product_option_value_id']; 
    $product_option_id = $result_for_base_a->rows[$j]['product_option_id']; 

    $result_for_base_c = $this->db->query("SELECT * FROM oc_product_option WHERE product_option_id = '$product_option_id'"); 
    $product_id = $result_for_base_c->row['product_id']; 
    $result_for_base_b = $this->db->query("SELECT * FROM oc_product_option_value WHERE product_option_value_id = '$product_option_value_id' AND product_id='$product_id'"); 
    $points = $result_for_base_b->row['points']; 

    $price = $result_for_base_b->row['price']; 
    $counts = $result_for_base_a->rows[$j]['quantity']; 
}
