不能插入數組表MySQL的PHP​​

Question

嗨，我想插入2個陣列在數據庫表中，並得到以下：

Warning: Invalid argument supplied for foreach() in 
C:\xampp\htdocs\sport\admin\model\competition\newsletter.php on line 9 

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\sport\admin\model\competition\newsletter.php on line 12 

Notice: Array to string conversion in C:\xampp\htdocs\sport\admin\model\competition\newsletter.php on line 18 

Notice: Array to string conversion in C:\xampp\htdocs\sport\admin\model\competition\newsletter.php on line 18Notice: Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''customer_transaction'(customer_id,amount) VALUES'Array,Array'' at line 1 

Error No: 1064 
INSERT INTO 'customer_transaction'(customer_id,amount) VALUES'Array,Array' in C:\xampp\htdocs\sport\system\database\mysql.php on line 49 

如何解決這一切。下面是代碼： 這是Opencart的模塊文件

$sql = "SELECT DISTINCT competition_rate, customer_id FROM " . DB_PREFIX . "customer WHERE competition_rate NOT LIKE 0"; 
    $query = $this->db->query($sql); 
$rates = array(); 
$customer_ids = array(); 
foreach($query->row['competition_rate'] as $result){ 
    $rates[] = $result * $data['name']; 
} 
foreach($query->row['customer_id'] as $result2){ 
    $customer_ids[] = $result2; 
} 

$sums = $rates; 
$ids = $customer_ids; 
$this->db->query("INSERT INTO 'customer_transaction'(customer_id,amount) VALUES'".$ids.",".$sums."'"); 
    } 

Answer 1

我構建查詢而獲取的結果，那麼concatinate件，以形成最終的INSERT查詢：

$arr = array(); 
foreach($query->rows as $result){ 
    $arr []= '('. implode(', ', array($result['customer_id'], $result['competition_rate'] * $data['name'])) . ')'; 
} 
$this->db->query("INSERT INTO 'customer_transaction'(customer_id,amount) VALUES " . implode(', ', $arr)); 

Answer 2

你不能用數組串聯字符串。 $ids和$sums必須是一個字符串。

Answer 3

我寧願環在$row，然後作出一個INSERT查詢在任何迭代

$query = $this->db->query($sql); 

foreach($query->row as $result){ 
    $rates = $result['competition_rate'] * $data['name']; 
    $ids = $result['customer_id']; 

    $this->db->query("INSERT INTO customer_transaction (customer_id,amount) VALUES ('".$ids.",".$rates."')"); 
} 

請注意，您引號括起來的表名，但實際上你不應該，如果你願意，你可以使用反引號（ `）

Answer 4

試試這個，你的表名無需被包裹在'和values()()括號內。

$this->db->query("INSERT INTO `customer_transaction` (customer_id,amount)        
    VALUES ('$ids','$sums') "); 
     ..^     ^... 

代替

$this->db->query("INSERT INTO 'customer_transaction'(customer_id,amount) VALUES'".$ids.",".$sums."'");
