我正在为宠物创建一个网站。我希望创建一个页面，宠物主人可以在其中注册和添加他的宠物。我制作了一个表单并放置了 javascript 来添加更多宠物，当点击“添加更多宠物”链接时，它会创建新字段。但我无法将这些信息收集到 php 变量中。链接在这里：http ://animalswecare.in/mypet.php

我有 php 和 mysqli 的工作知识。

我的 php 代码 if ( isset( $_POST['mypet'] ) ) {

   $name         = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['name'] ) )  );
  $email     = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['email'] ) )  );
  $password    = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['password'] ) )  );
   $gender       = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['sex'] ) )  );
     $contact     = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['contact'] ) )  );
   $country     = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['country'] ) )  );
    $state       = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['state'] ) )  );
  $city        = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['city'] ) )  );
   //$photo       = mysqli_real_escape_string ( $dbc, strip_tags ( trim ( $_POST['picture'] ) )  );

 $fname = mysqli_real_escape_string ( $dbc, $_FILES['picture']['name'] );
            $ext=$_FILES['picture']['name'];
            $targetpath = "images/user/big/";

            if($ext !="")
            {
        $ext = explode(".",$ext);
        if($ext[1]=="jpg" || $ext[1]=="gif" || $ext[1]=="jpeg" || $ext[1]=="png" || $ext[1]=="bmp" || $ext[1]=="wbmp" || $ext[1]=="JPEG" || $ext[1]=="JPG" || $ext[1]=="GIF" || $ext[1]=="PNG" || $ext[1]=="BMP")

您的 petname 字段 HTML 设置了重复条目 ( name="petname[]") 的正确属性，但您的类型、性别和品种输入需要[]在其名称属性的末尾具有: <input type="text" name="type[]">。

在 PHP 方面，您应该在POST（或者GET如果您的表单方法是GET）数组中看到类似这样的内容：$_POST["petname"][0]和$_POST["petname"][1]. 所以我会做这样的事情：

foreach ($_POST["petname"] as $name)
{
    // store $name in the database
}


foreach ($_POST["type"] as $type)
{
    // store $type in the database
}

etc...

由于您使用多个字段，您可能希望像这样构造它们：

<input type="text" name="pet[name][]">
<input type="text" name="pet[type][]">

然后您可以执行以下操作：

foreach ($_POST["pet"] as $pet)
{
    // store $pet["name"] in the database
    // store $pet["type"] in the database
    // etc.
}

查看$_POST数据的最佳方式如下：

print_r($_POST);

然后您将能够找出是否有任何错误，但没有任何 PHP 代码，我们无法准确告诉您问题所在。

$_POST将包含从表单接收到的数据：

$_POST['name'], $_POST['email'], 等等。

$petname = $_POST['form controls name']

$_POST 包含表单在方法发布时接收到的数据，默认为 $_GET[' ']。
