插入多個值不起作用

-5

我正在嘗試爲多個插入值編寫代碼，但無法正常工作。錯誤是這個警告：爲foreach（）提供的無效參數。任何幫助將升值。插入多個值不起作用

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)); 
     } 
    } 
}

你有沒有問過這個了嗎？ http://stackoverflow.com/questions/24421680/insert-multiple-values-in-php-mysql –

閱讀此：http://www.php.net/manual/en/control-structures.foreach.php – Locke

首先錯誤是在這裏：

if (count($counter > 0))

應該

if (count($counter) > 0)

，你可能會得到警告，因爲count($counter)可能是0，由於僞造的，如果條件下，它可能在非數組或空數組上執行for循環，因此出錯

1。是你的情況「$計數器」不是一個數組或對象來遍歷...

我只是建議，因爲你已經有一半的硬編碼SQL語句

$結果= $ （'$ counter'，'$ pr'，'$'，'$''，''）查詢（「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「自動化」你的名字值對進入SQL，你就必須準備一個更完整的「$ =新陣列（）」 ...這樣的事情

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

然後你就不會需要一個for循環任何更多與「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=""; 
      } 
     } 




    } 
}
