刷新页面后如何记住表格中的输入数据? [英] how to remember input data in the forms even after refresh page?

问题描述

为了使表单即使在刷新页面后仍能记住用户的先前输入或当前输入，该怎么做?

what to do in order to make the form remember the previous input or the current input of the user even after he/she refreshed the page ?

我应该这样做，

            <div class="row">
             <label>Contact Messenger </label>
             <input type="text" name="messenger" id="messenger" size="50" maxlength="50" value="<?php echo $_SESSION['messenger']; ?>"/>
            </div>

或

            <div class="row">
             <label>Contact Messenger </label>
             <input type="text" name="messenger" id="messenger" size="50" maxlength="50" value="<?php echo $_POST['messenger']; ?>"/>
            </div>

或

有一个窍门吗?..如何?

there's a trick to do it ?..how ?

推荐答案

在您提交表单的页面上执行类似的操作

on the page where your form is submitting do something like this

    session_start();
    $_SESSION['data'] = $_POST['data'];
    $_SESSION['data_another'] = $_POST['data_another'];

然后您可以在任何这样的位置访问这些会话变量

and than you can access those session variables any where like this

    session_start(); // this should be at the top of the page before any html load
    <input type="text" name="name" value="<?php echo $_SESSION['data'];?>"/>

在成功调用后刷新您的页面

refresh your page on success call like this

     $.ajax({
           type: "POST",
           url: "yourfile.php",
           data: 'data='+ data,
           success: function(){
               location.reload();
           }
       });
