具有相同名称的多个隐藏输入，始终检索最后一个输入 [英] Multiple hidden input with same name, always retrieve the last input

问题描述

   foreach ($graphEdge as $graphNode) {
    echo
      "<div class='form-check mb-3'>" .
        "<input type='radio' name='fb_profile' class='form-check-input' value='".$graphNode['name']."'>" .
        "<img class='mr-2' src='" . $graphNode['picture']['url'] . "'>" . 
        "<label class='form-check-label' for='fb_profile'>" . 
        $graphNode['name'] . '</label>' . 
      "</div>";

    echo "<input type='hidden' name='fb_access_token' value='" . $graphNode['access_token'] . "'>";
    echo "<input type='hidden' name='fb_id' value='" . $graphNode['id'] . "'>";
    }

正如标题所示，我有3个名为"fb_id"的隐藏输入，当我在表单中进行POST时将始终检索最后的隐藏输入，而fb_access_token将始终正确进行POST.

As the title suggests, I have 3 hidden inputs named 'fb_id' that when I POST in a form will always retrieve the last hidden input yet fb_access_token will always POST correctly.

好.从对话中可以看到，您想获取值，该值取决于radio. 您可以这样操作:

Ok. As I see from conversation, you want to get values, which depends on radio. You can do it this way:

foreach ($graphEdge as $graphNode) {
    echo
        "<div class='form-check mb-3'>" .
            "<input type='radio' name='fb_profile' class='form-check-input' value='".$graphNode['name']."'>" .
            "<img class='mr-2' src='" . $graphNode['picture']['url'] . "'>" . 
            "<label class='form-check-label' for='fb_profile'>" . 
    $graphNode['name'] . '</label>' . 
        "</div>";

   echo "<input type='hidden' name='fb_access_token[".$graphNode['name']."]' value='" . $graphNode['access_token'] . "'>";
   echo "<input type='hidden' name='fb_id[".$graphNode['name']."]' value='" . $graphNode['id'] . "'>";
}

然后您可以通过radio值来获取选定的值，如下所示(假设您的表单发送POST请求):

And then you can get selected values by radio value like this (let's suppose your form sends POST request):

$profile = $_POST['fb_profile'];
$accessToken = $_POST['fb_access_token'][$profile];
$id = $_POST['fb_id'][$profile];
