您好我试图仅从一个按钮提交多个表单值我有10个记录和一个记录有一个提交按钮和10个记录有10个按钮提交我想要的应该只有一个提交按钮我可以从一个按钮提交他整整10条记录：

 echo "<table class='table table-hover table-responsive table-bordered'>";

// our table heading
echo "<tr>";
echo "<th class='textAlignLeft'>Product Name</th>";
echo "<th>Price</th>";
echo "<th style='width:5em;'>Quantity</th>";
echo "<th>Image</th>";
echo "<th>Action</th>";


echo "</tr>";

while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
    extract($row);


    //creating new table row per record
    echo "<tr>";
    echo "<td>";
    echo "<div class='product-id' style='display:none;'>{$id}</div>";
    echo "<div class='product-name'>{$name}</div>";
    echo "</td>";
    echo "<td>&#36;" . number_format($price, 2, '.' , ',') . "</td>";
    if(isset($quantity)){
        echo "<td>";
        echo "<input type='text' name='quantity' value='{$quantity}' disabled class='form-control' />";
        echo "</td>";

        echo "<td>";

        echo "</button>";
        echo "</td>";
        echo "</td>";
    }else{
        echo "<td>";
        echo "<input type='number' name='quantity[]' value='1' class='form-control'/>";
        echo "</td>";
        echo "<td><img src='product-images/{$image}' width='60' height='60'</td>";
        echo "<td>";
        echo "<button class='btn btn-primary add-to-cart'>";
        echo "<span></span>Submit to cart";
        echo "</button>";
        echo "</td>";
    }

    echo "</tr>";
}

echo "</table>";

}    我想要的只有一个按钮我可以提交我所有的价值观：任何帮助都会受到高度赞赏：

     $action = isset($_GET['action']) ? $_GET['action'] : "";
     $product_id = isset($_GET['product_id']) ? $_GET['product_id'] : "1";
     $name = isset($_GET['name']) ? $_GET['name'] : "";
      $quantity = isset($_GET['quantity']) ? $_GET['quantity'] : "1";
     $image = isset($_GET['image']) ? $_GET['image'] : "1";


      if($action=='added'){
          echo "<div class='alert alert-info'>";
         echo "<strong>{$name}</strong> added to your cart!";
          echo "</div>";
        }

       else if($action=='failed'){
          echo "<div class='alert alert-info'>";
           echo "<strong>{$name}</strong> failed to add to your cart!";
          echo "</div>";
            }

             // left join to select products
              $query = "SELECT p.id, p.name, p.price, p.image, ci.quantity 
            FROM products p 
             LEFT JOIN cart_items ci
            ON p.id = ci.product_id 
         ORDER BY p.name";

         $stmt = $con->prepare( $query );
        $stmt->execute();

       // count number of products returned
         $num = $stmt->rowCount();

使用名称数量[]而不是数量。通过这种方式，您可以将数据作为数组接收。循环后只使用一个提交按钮。

echo "<input type='number' name='quantity[]' value='1' class='form-control'/>";

然后使用foreach

接收它 
foreach($_POST['quantity'] as $qty)
{
   echo $qty;
   //Here you will receive all the quantities one by one.
}

形成代码

<?php

 echo "<table class='table table-hover table-responsive table-bordered'>";

// our table heading
echo "<tr>";
echo "<th class='textAlignLeft'>Product Name</th>";
echo "<th>Price</th>";
echo "<th style='width:5em;'>Quantity</th>";
echo "<th>Image</th>";


echo "</tr>";

while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
    extract($row);


    //creating new table row per record
    echo "<tr>";
    echo "<td>";
    echo "<div class='product-id' style='display:none;'>{$id}</div>";
    echo "<div class='product-name'>{$name}</div>";
    echo "</td>";
    echo "<td>&#36;" . number_format($price, 2, '.' , ',') . "</td>";
    if(isset($quantity)){
        echo "<td>";
        echo "<input type='text' name='quantity[]' value='{$quantity}' disabled class='form-control' />";
        echo "</td>";

        echo "<td>";
        echo "</td>";
        echo "<td>";
        echo "</td>";
    }else{
        echo "<td>";
        echo "<input type='number' name='quantity[]' value='1' class='form-control'/>";
        echo "</td>";
        echo "<td><img src='product-images/{$image}' width='60' height='60'</td>";
        echo "<td>";
        echo "</td>";
    }

    echo "</tr>";
}
    echo "<tr><td colspan='4'>";
        echo "<button class='btn btn-primary add-to-cart' type='submit'>";
        echo "<span></span>Submit to cart";
        echo "</button>";
    echo "</td></tr>";

echo "</table>";
