当我提交以下表单，并在单独的页面上打印POST数据的数组时，我得到一个空数组。我的数据在哪里，为什么不发布到flupdate.php？我测试了PHP及其声音。怎么了？
<form action="inc/flupdate.php" method="POST" name="form-wizard">

答案 0 :(得分：0)
您可以使用html属性 readonly 而不是disabled。无法修改只读输入字段（但是，用户可以对其进行制表，突出显示，并从中复制文本）。
例如：
<input type="text" name="firstname" placeholder="<?php if(!empty($_SESSION["user_first"])){ echo $_SESSION["user_first"];}else { echo 'First';} ?>" class="form-control" data-parsley-group="wizard-step-1" readonly />
