Question

朋友们，我已经创建了一个表单，并尝试为每个字段设置cookie，我成功为输入文本框设置了cookie，但我没有对textarea字段和下拉列表执行相同的操作。以及复选框。表格如下......

<input name="date" type="text" size="10" value="<?php if(isset($_COOKIE["date"])) echo $_COOKIE["date"];?>" onblur="setCookie(this.name,this.value,60*60*2)" /></td>
          Order Number:
          <input name="order_num" type="text" size="10" value="<?php if(isset($_COOKIE["order_num"])) echo $_COOKIE["order_num"];?>" onblur="setCookie(this.name,this.value,60*60*2)" />
         First Name:
          <td><input name="fname" type="text" value="<?php if(isset($_COOKIE["fname"])) echo $_COOKIE["fname"];?>" onblur="setCookie(this.name,this.value,60*60*2)"/></td>
          Last Name:
          <td><input name="lname" type="text" value="<?php if(isset($_COOKIE["lname"])) echo $_COOKIE["lname"];?>" onblur="setCookie(this.name,this.value,60*60*2)"/>

          Image Submitted:
          <input name="image" type="text" value="<?php if(isset($_COOKIE["image"])) echo $_COOKIE["image"];?>" onblur="setCookie(this.name,this.value,60*60*2)"/>
          General Comments:
         <textarea name="gen_comments" cols="50" rows="6"  onblur="setCookie(this.name,text,60*60*2)" ><?php if(isset($_COOKIE["gen_comments"])) { echo $_COOKIE["gen_comments"];}?></textarea>

          Internal Comments:
          <textarea name="int_comments" cols="50" rows="6" onblur="setCookie(this.name,text,60*60*2)"><?php if(isset($_COOKIE["int_comments"])) { echo $_COOKIE["int_comments"];}?></textarea>

关于如何使用PHP设置/读取/删除cookie的简单示例：

<?php

// set a cookie
setcookie("cookiename", "cookievalue", time()+3600);

// read a cookie
if (isset($_COOKIE["cookiename"])) {
  $mycookievalue = $_COOKIE["cookiename"];
}

// delete a cookie
setcookie("cookiename", "", time()-3600);

?>

根据您的实际情况，只需重复您需要存储的每个字段。

<强>如，

<?php
foreach($_POST as $key =>$value) {
  setcookie($key, $value, time()+3600);
}
?>

要回答您的问题，尽管有更好的方法可以做到这一点：

必须在发送标题之前设置PHP Cookie（在给出任何输出之前，因此您无法按照自己的意愿设置它们）

您可以选择以下选项：

 -set the cookies using javascript
 -Create a file which acts as the forms action, and in that file pull all the $_POST values and set them there.

但我再说一遍，有更好的方法可以做到这一点。

存储cookie并使用php以html格式值检索它们
