PDO在foreach循環中更新行值

Question

我在foreach循環內創建了一個表，在表中顯示了所有記錄。然後我包含一個SQL更新與選擇和更新一個數組值。當我選擇不同的值時，循環會更新表中的所有記錄，而不是隻有一個被更新。我整天都在苦苦掙扎，請幫助我。

如果foreach是錯誤的方式，我將非常感謝您對如何顯示可顯示記錄並允許更新每個陣列的表的建議。

<?php 
      foreach ($stmt as $key => $row) 
      { 

       $newcustomerid = htmlentities($row['customer_id']); 

       echo '<tr><td>' . htmlentities($row['customer_company']) . '</td>'; 
       echo '<td> id:' . $newcustomerid . 'key: ' . $key .'</td>'; 
       echo '<td>' . htmlentities($row['customer_email']) . '</td>'; 
       echo '<td>' . htmlentities($row['customer_phone']) . '</td>'; 
       echo '<td>' . htmlentities($row['customer_country']) . '</td>'; 
       echo '<td>' . htmlentities($row['customer_city']) . '</td>'; 
       echo '<td>' . htmlentities($row['customer_segment']) . '</td>'; 
       echo '<td>' . htmlentities($row['customer_updated']) . '</td>'; 
       $customer_status = htmlentities($row['customer_status']); 

       if(isset($_POST['Submitbb'])){ //check if form was submitted 
       $input = $_POST['Submitbb']; //get input text 

        $stmtUpdateStatus = $conn->prepare("UPDATE user_customers SET `customer_status` = :customer_status WHERE `customer_id` = :customer_id"); 
        $stmtUpdateStatus->execute(array(':customer_status' => $input, ':customer_id' => $row['customer_id'])); 
       } 

       echo '<td> 
        <form action="" method="post"> 
         <select name="Submitbb" onchange="this.form.submit();"> 
          <option> - ' . $customer_status . ' - </option> 
          <option>Susisiekti</option> 
          <option>Priminimas 1</option> 
          <option>Priminimas 2</option> 
          <option>Paskambinti</option> 
          <option>Netinkamas klientas</option> 
          </select> 
        </form> 
       </td>'; 


       echo '<td>' . 'Išsaugoti' . '</td></tr>'; 

      } 



     ?> 

謝謝。

你可以使用一個隱藏的輸入捕捉行中的數據庫要更新

echo '<td> 
       <form action="" method="post"> 
        <input name="customer_id" type="hidden" value="'.$newcustomerid.'"/> <!-- hidden --> 
        <select name="Submitbb" onchange="this.form.submit();"> 
         <option> - ' . $customer_status . ' - </option> 
         <option>Susisiekti</option> 
         <option>Priminimas 1</option> 
         <option>Priminimas 2</option> 
         <option>Paskambinti</option> 
         <option>Netinkamas klientas</option> 
         </select> 
       </form> 
      </td>'; 

然後進行比較時的形式張貼

  if(isset($_POST['Submitbb'])){ //check if form was submitted 
      $input = $_POST['Submitbb']; //get input text 
      $customer_id = $_POST['customer_id']; // get the posted customer ID 
      if($row['customer_id'] == $customer_id){ 

        $stmtUpdateStatus = $conn->prepare("UPDATE user_customers SET `customer_status` = :customer_status WHERE `customer_id` = :customer_id"); 
        $stmtUpdateStatus->execute(array(':customer_status' => $input, ':customer_id' => $customer_id)); 
       } 
      }
