仅卸载特定类型的数据库

Question

有一个循环可以创建一个启动文件：

<?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'];
}

我需要添加一条规则，该规则将仅为那些选择的选项创建可引导数据。

表中有一个＆＃39;类型＆＃39;，有一个选择，复选框，广播，图像等。但是我需要循环忽略除select之外的所有类型。

您只需在条目中添加条件type = 'select'即可。尝试这样的事情：

<?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'];
}
