foreach重复上一次迭代

标签： php foreach

我很抱歉重复我关于我的另一篇文章的问题，但它没有解决，因此我在开发过程中完全被阻止了。我是体育俱乐部的志愿者，允许会员租用滑雪设备。我有3个文件：成员做出选择的第一个“choice.php”，第二个“summary.php”，它允许他添加材料或确认他的选择，第三个“confirm.php”，他添加个人数据和我通过电子邮件确认订单的地方。我的问题是，当所有选择都已完成并且用户想要确认时，最后一行加倍。我试着把

UNSET();

指示循环内外的不同位置，但没有任何改变。怎么避免这个？这是我的文件（请注意这些是干净的文件，我删除了所有控件，以尽可能缩短文件）。非常感谢您的帮助。 第一个文件“choice.php”：

}
$_SESSION['ctform']['success'] = false;

这是我的第二个文件“summary.php”的代码：

<?php session_start(); ?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

    display: block;
    font-family: "Courier New", monospace;
    font-stretch: normal;
    font-size: 12px;
    white-space: pre;
} 
</style>
</head>
<body>     
<?php
$select = array();
$select['type'] = $_SESSION['ct_ski'];
$select['length'] = $_SESSION['ct_length'];
$select['boots'] = $_SESSION['ct_boots'];
$select['size'] = $_SESSION['ct_size'];
if(!isset($_SESSION['panier']))
{
$_SESSION['panier'] = array();
$_SESSION['panier']['type'] = array();
$_SESSION['panier']['length'] = array();
$_SESSION['panier']['boots'] = array();
$_SESSION['panier']['size'] = array();
}   
array_push($_SESSION['panier']['type'],$select['type']);
array_push($_SESSION['panier']['length'],$select['length']);
array_push($_SESSION['panier']['boots'],$select['boots']);
array_push($_SESSION['panier']['size'],$select['size']);
$type = $_SESSION['panier']['type'];
$length = $_SESSION['panier']['length'];
$boots = $_SESSION['panier']['boots'];
$size = $_SESSION['panier']['size'];     
  echo "Your summary :<br><br>
  <pre>
  Type                 | Length              | Boots                  |       Size</pre>";        
  foreach ($type as $key => $value) {
   unset($value);
   $type[$key] = str_pad($type[$key], 20);
   $length[$key] = str_pad($length[$key], 19);
   $boots[$key] = str_pad($boots[$key], 22);
   $size[$key] = str_pad($size[$key], 15);   
   echo "<pre>  " .$type[$key] . " | " . $length[$key] . " | " .     $boots[$key] . " | " . $size[$key] .  "</pre>";    
  }   
   /* $_SESSION['type'] = $type[$key];

          <hr>
          <a href="delete.php">Clic here to delete all</a>
</body>
</html>

以下是我的最终文件“confirm.php”的代码，其中您看到最后一个选项的错误加倍：

<?php session_start(); ?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>Confirmation</title>
<style>

    display: block;
    font-family: "Courier New", monospace;
    font-stretch: normal;
    font-size: 12px;
    white-space: pre;
} 
</style>
</head>
<body>     
<?php       
$select = array();
$select['type'] = $_SESSION['ct_ski'];
$select['length'] = $_SESSION['ct_length'];
$select['boots'] = $_SESSION['ct_boots'];
$select['size'] = $_SESSION['ct_size'];

if(!isset($_SESSION['panier']))
{
    $_SESSION['panier'] = array();
    $_SESSION['panier']['type'] = array();
    $_SESSION['panier']['length'] = array();
    $_SESSION['panier']['boots'] = array();
    $_SESSION['panier']['size'] = array();
}   
array_push($_SESSION['panier']['type'],$select['type']);
array_push($_SESSION['panier']['length'],$select['length']);
array_push($_SESSION['panier']['boots'],$select['boots']);
array_push($_SESSION['panier']['size'],$select['size']); 
$type = $_SESSION['panier']['type'];
$length = $_SESSION['panier']['length'];
$boots = $_SESSION['panier']['boots'];
$size = $_SESSION['panier']['size'];     
  echo "Your summary :<br><br>
  <pre>
  Type                 | Length              | Boots                  | Size</pre>";          
  foreach ($type as $key => $value) {
   unset($value);
   $type[$key] = str_pad($type[$key], 20);
   $length[$key] = str_pad($length[$key], 19);
   $boots[$key] = str_pad($boots[$key], 22);
   $size[$key] = str_pad($size[$key], 15);  
   echo "<pre>  " .$type[$key] . " | " . $length[$key] . " | " . $boots[$key] . " | " . $size[$key] .  "</pre>";    
  }          
?>
          <hr>
          <a href="delete.php">Clic here to delete all</a>
          <hr><br>Personal information here... (Name, Firstname, email, etc.) 
</body>
</html>

最后是一个简短的文件，只需点击一下即可轻松删除所有选项

<?php session_start();
$vide = false;
    if(!isset($_SESSION['panier']['verrouille']) || $_SESSION['panier']['verrouille'] == false)
    {
        if(isset($_SESSION['panier']))
        {
            unset($_SESSION['panier']);
            if(!isset($_SESSION['panier']))
            {
                $vide = true;
            }
        }
        else
        {
             $vide = "inexistant";
        }
    } 
?>
<html>
<head>
<script type="text/javascript">
     window.location.replace("choice.php");
</script>
</head>
</html>
