在复选框中存储多个值以检查php

StanGaming 666

我有这个学校的任务，在mc和bk之间进行比较。

现在我有这个：

<html>
<head>

<link rel="stylesheet" type="text/css" href="style1.css" />

     </head>
     <?php

     if(isset($_POST['formSubmit'])) 
         {
             $breakfastMC = $_POST['BreakfastMC'];
             $breakfastBK = $_POST['BreakfastBK'];
             $sumMC = 0;
             $sumBK = 0;
             if(empty($breakfastMC)) 
                 {
                     echo("<p>You didn't select any food in MC.</p>\n");
                 } 
             else 
                 {
                     $MC = count($breakfastMC);

                     echo("<p>You selected for MC = $MC:<br/>");
                     for($i=0; $i < $MC; $i++)
                         {   
                             echo( "Price = " . $breakfastMC[$i] . "<br/>");
                             $sumMC += floatval( $breakfastMC[$i] );
                         }
                     echo "Total MC = " . $sumMC . "<br/>";
                 }
             if(empty($breakfastBK))

                             $sumBK += floatval( $breakfastBK[$i] );

                 echo 'equal';
             else if ( $sumBK > $sumMC )
                 echo 'BK more expensive than MC';
             else echo 'MC more expensive than BK';

此代码比较MC和BK中的值，但仅比较价格。是否可以通过某种方式在卡路里的复选框中添加诸如value2的值，因此也可以对它们进行比较？

像这样的东西：

<input type="checkbox" name="BreakfastMC[]" value1="10" value2="20"/>

还是其他方式？

不要在价格中输入价格，只需在其中输入产品的标识符即可，例如

 <div class="squaredOne"><input type="checkbox" name="BreakfastMC[]" id="squaredOne1"   value="croissant"/>
 <label for="squaredOne1"></label>
 <div class="McText">Croissant jam en boter Prijs = 2       Cal = 100</div>
 </div>
 <div class="squaredOne"><input type="checkbox" name="BreakfastMC[]"  id="squaredOne2"   value="pancakes"/>
 <label for="squaredOne2"></label>
 <div class="McText">Pancakes met stroop <br /></div>
 </div>
 <div class="squaredOne"><input type="checkbox" name="BreakfastMC[]"  id="squaredOne3"   value="mcmuffinbacon"/>
 <label for="squaredOne3"></label>
 <div class="McText">McMuffin met Bacon en Ei <br /></div>
 </div>
 <div class="squaredOne"><input type="checkbox" name="BreakfastMC[]"  id="squaredOne4"   value="mcmuffinkaas"/>
 <label for="squaredOne4"></label>
 <div class="McText">McMuffin met Kaas <br /></div>
 </div>

使用数组将产品ID映射到价格和卡路里：

$MCmenu = array('croissant' => array('price' => 2, 'calories' => 100),
                'pancakes' => array('price' => 3, 'calories' => 200),
                'mcmuffinbacon' => array('price' => 3, 'calories' => 450),
                'mcmuffinkaas' => array('price' => 4, 'calories' => 350),
                ...);
$BKmenu = array('pancakes' => array('price' => 1.5, 'calories' => 364),
                'toastie' => array('price' => 1.5, 'calories' => 359),
                'breakfastburger' => array('price' => 3, 'calories' => 825),
                ...);

然后，在计算价格时，您可以执行以下操作：

 foreach($breakfastMC AS $bk)
     {
         echo( "Price = " . $MCmenu[$bk]['price'] . "<br/>");
         echo( "Calories = " . $MCmenu[$bk]['calories'] . "<br/>");
         $sumMC += $MCmenu[$bk]['price'];
         $caloriesMC += $MCmenu[$bk]['calories'];

     }

为了进一步改善这一点，您可以将描述放入菜单数组中

$MCmenu = array('croissant' => array('price' => 2, 'calories' => 100, 'desc' => 'Croissant jam en boter Prijs'),
                'pancakes' => array('price' => 3, 'calories' => 200, desc => 'Pancakes met stroop'),
                'mcmuffinbacon' => array('price' => 3, 'calories' => 450, 'desc' => 'McMuffin met Bacon en Ei')
                ...);

然后，您可以从中生成HTML：

foreach ($MCmenu as $id => $item) {
    $price = $item['price'];
    $cal = $item['calories'];
    $desc = $item['desc'];
    ?>
 <div class="squaredOne"><input type="checkbox" name="BreakfastMC[]" id="BreakfastMC<?php echo $id ?>"   value="<?php echo $id ?>"/>
 <label for="BreakfastMC<?php echo $id ?>"></label>
 <div class="McText"><?php echo $desc ?> = <?php echo $price ?>       Cal = <?php echo $cal ?></div>
 </div>
<?php }
