Javascript 如何移动上一页并在字段中显示值？

我制作了两个网页，我想从第二页的第一页获取数据，如果用户单击编辑消息，然后移动第一页并显示用户输入的数据，以下是我的代码：

first.php

    <h1>Compose Message</h1>
    <script type="text/javascript" src="<?=MURL?>/js/ckeditor/ckeditor.js"></script>

    </tr>
    <tr>

        <td>
            <select name="events[]" multiple size="10" >
            <?
            $select = sprintf ("SELECT event_id,event_name
                            FROM `events`
                            WHERE (`user_id` = '%s') order by event_name",
                            $GLOBALS ['mysqli']->real_escape_string ($_SESSION['user_id']));

            $res = $GLOBALS ['mysqli']->query ($select) or die ($GLOBALS ['mysqli']->error . __LINE__);
            if ($res->num_rows > 0)
            {

                while($row = $res->fetch_assoc ())
                {

            ?>
              <option value="<?=$row['event_id']?>"><?=$row['event_name']?></option>

Compose消息
使用javascript转到上一页

window.history.go(-1)

由于您希望将表单发送到两个不同的脚本，我建议您使用两个表单：

<form action="formfilling.php">
  <?php
    //prepare the recived POST to send back:
    foreach( $_POST as $key => $value ){
      if( is_array($_POST[$key]) ){  //if post is array e.g. your events[]
        foreach( $_POST[$key] as $subvalue ){
          echo '<input type="hidden"'
              .' name="'.htmlspecialchars($key).'[]"'
              .' value="'.htmlspecialchars($subvalue).'">'."\n";
        }      
      } else{
        echo '<input type="hidden"'
            .' name="'.htmlspecialchars($key).'"'
            .' value="'.htmlspecialchars($value).'">'."\n";
      }
    }
  ?>
  <input type="submit" class="button edit" name="submit_skip" value="Edit Message" />
</form>

<form action="submitemail.php">
  <?php //possibly show message? ?>
  <input type="submit" class="button email" name="submit_email" value="Send Message" />
</form>

对于数组，类似于

if( !empty($_POST['inputName']) ){
   foreach( $_POST['inputName'] as $val ){
      //Test if the current option has the value of $val if so:
      echo /*OPTION with SELECTED*/;
   }
}

打印/回显$\u POST/$\u GET时始终使用HTML转义

=>不要信任用户！

=>在PHP中有一个
htmlspecialchars（）
函数
我是否正确理解您的问题是您有一个表单，其中有两个按钮1）“提交消息”2“返回”？你想得到2“返回”开始工作吗？是的，我想在单击“返回”时返回表单字段中显示的上一次发布的数据，但如何将$\u POST附加到this@Arif我的回答是：）
if( !empty($_POST['inputName']) ) echo htmlspecialchars($_POST['inputName']);

if( !empty($_POST['inputName']) ){
   foreach( $_POST['inputName'] as $val ){
      //Test if the current option has the value of $val if so:
      echo /*OPTION with SELECTED*/;
   }
}
