为数据库查询添加值

Question

我想向INSERT语句添加另一个值，但无论我做什么，它都会导致各种错误。有人能告诉我正确的方式来编码吗？

我原来的工作代码是这样的：

$sql = "INSERT INTO `act` (`department`) VALUES ('". implode("'),('", $dept) . "')"; 

我曾尝试在其他之中：

$sql = "INSERT INTO `act` (`department`,`item`) VALUES ('". implode("'),('", $dept) . "','". implode("'),('", $box) . "')";

也许我应该张贴我的代码生成结果：

$dept = array(); 
$box = array(); 

while ($row = mysql_fetch_array($result)) { 
      $dept[] = $row['department']; 
      $box[] = $row['custref']; 
} 

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); 
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . "GMT"); 
header("Cache-Control: no-cache, must-revalidate"); 
header("Pragma: no-cache"); 
header("Content-type: application/json"); 
$json = ""; 
$json .= "{\n"; 
$json .= "dept: [\"". implode('","', $dept). "\"],\n"; 
$json .= "box: [\"". implode('","', $box) ."\"]\n"; 
$json .= "}\n"; 
echo $json; 

$sql = "INSERT INTO `act` (`department`) VALUES ('". implode("'),('", $dept) . "')"; 
$result = runSQL($sql); 

Answer 1

多插入应该是我n中的格式：

INSERT INTO `act` (`department`, `item`) VALUES ('dept1', 'item1'), ('dept2', 'item2'), ('dept1', 'item1'), ('dept3', 'item3');, 

$insert = array(); 
for ($i=0; $i<sizeof($dept); $i++) { 
    $insert[] = '(\'' . $dept[$i] . '\',\'' . $box[$i] . '\')'; 
} 

$sql = "INSERT INTO `act` (`department`,`item`) VALUES " . implode(',', $insert); 

Answer 2

你可以尝试这样的事情

$sql="INSERT INTO `act` 
     (`department`,`box`) 
     VALUES 
    "; 

foreach($dept as $index => $value) 
{ 
    $sql.=" 
     (
      '".mysql_real_escape_string($value)."', 
      '".mysql_real_escape_string($box[$index])."' 
     ),"; 
} 

$sql=rtrim($sql,',') ; 
$result = runSQL($sql);
