插入多个值不起作用

-5

我正在尝试为多个插入值编写代码，但无法正常工作。错误是这个警告：为foreach（）提供的无效参数。任何帮助将升值。插入多个值不起作用

if (isset($_POST['mul_pr'])) { 
$counter = $mysqli->real_escape_string($_POST["counter"]); 
$pr = $mysqli->real_escape_string($_POST["pr"]); 
$pr_qty = $mysqli->real_escape_string($_POST["pr_qty"]); 
$unit = $mysqli->real_escape_string($_POST["unit"]); 
$pr_date = $mysqli->real_escape_string($_POST["pr_date"]); 
$gss_date = $mysqli->real_escape_string($_POST["gss_date"]); 
$request = $mysqli->real_escape_string($_POST["requested"]); 
$approve = $mysqli->real_escape_string($_POST["approved"]); 
$desig_r = $mysqli->real_escape_string($_POST["designation_r"]); 
$desig_a = $mysqli->real_escape_string($_POST["designation_a"]); 
$year = $mysqli->real_escape_string($_POST["year"]); 
$pr_id = $mysqli->real_escape_string($_POST["pr_id"]); 

    if (count($counter > 0)) 
    { 
     $new = array(); 
     foreach ($counter as $key => $value) 
     { 
      $new[] = "('" . $counter . "', '" . $pr . "', '" . $pr_qty . "', '" . $unit . "','" . $pr_date . "', '" . $gss_date . "', '" . $request . "', '" . $approve . "' 
      , '" . $desig_r . "', '" . $desig_a . "', '" . $year . "', '" . $pr_id . "')"; 
     } 
     if (count($new) > 0) 
     { 
      $result = $mysqli->query("INSERT INTO purchase_request (counter, pr, total_quantity, unit, pr_date, gss_date, requested, designation_r, approved, designation_a,year,pr_id) 
      VALUES " . implode(', ', $new)); 
     } 
    } 
}

你有没有问过这个了吗？ http://stackoverflow.com/questions/24421680/insert-multiple-values-in-php-mysql –

阅读此：http://www.php.net/manual/en/control-structures.foreach.php – Locke

首先错误是在这里：

if (count($counter > 0))

应该

if (count($counter) > 0)

，你可能会得到警告，因为count($counter)可能是0，由于伪造的，如果条件下，它可能在非数组或空数组上执行for循环，因此出错

1。是你的情况“$计数器”不是一个数组或对象来遍历...

我只是建议，因为你已经有一半的硬编码SQL语句

$结果= $ （'$ counter'，'$ pr'，'$'，'$''，''）查询（“INSERT INTO purchase_request（counter，pr，total_quantity，unit，pr_date，gss_date，requested，designation_r，approved，designation_a，year，pr_id）

VALUES ''）;

2。另外，如果你想“自动化”你的名字值对进入SQL，你就必须准备一个更完整的“$ =新阵列（）” ...这样的事情

$new["counter"] = $mysqli->real_escape_string($_POST["counter"]); 
$new["pr"] = $mysqli->real_escape_string($_POST["pr"]); 
//and so on...

然后你就不会需要一个for循环任何更多与 “array_keys（$新）”

$result = $mysqli->query("INSERT INTO purchase_request (".implode(",", array_keys).") 
     VALUES ('" . implode("','" , array_values($new))) . "');";

Use this , it work for u 

if (isset($_POST['mul_pr'])) { 
$counter = $mysqli->real_escape_string($_POST["counter"]); 
$pr = $mysqli->real_escape_string($_POST["pr"]); 
$pr_qty = $mysqli->real_escape_string($_POST["pr_qty"]); 
$unit = $mysqli->real_escape_string($_POST["unit"]); 
$pr_date = $mysqli->real_escape_string($_POST["pr_date"]); 
$gss_date = $mysqli->real_escape_string($_POST["gss_date"]); 
$request = $mysqli->real_escape_string($_POST["requested"]); 
$approve = $mysqli->real_escape_string($_POST["approved"]); 
$desig_r = $mysqli->real_escape_string($_POST["designation_r"]); 
$desig_a = $mysqli->real_escape_string($_POST["designation_a"]); 
$year = $mysqli->real_escape_string($_POST["year"]); 
$pr_id = $mysqli->real_escape_string($_POST["pr_id"]); 

    if (count($counter) > 0)) 
    { 
     $new = array(); 
     for($i=0;$i<count($counter);$i++) 
     { 
      $new[] = "('" . $counter . "', '" . $pr . "', '" . $pr_qty . "', '" . $unit . "','" . $pr_date . "', '" . $gss_date . "', '" . $request . "', '" . $approve . "' 
      , '" . $desig_r . "', '" . $desig_a . "', '" . $year . "', '" . $pr_id . "')"; 

      if (count($new) > 0) 
      { 
      $result = $mysqli->query("INSERT INTO purchase_request (counter, pr, total_quantity, unit, pr_date, gss_date, requested, designation_r, approved, designation_a,year,pr_id) 
      VALUES " . implode(', ', $new)); 
      $new=""; 
      } 
     } 




    } 
}
