 if（$ _SESSION ['security_code'] == $ _POST ['security_code']&&！empty （$ _SESSION ['security_code']））{
 //在此输入您处理表单的代码，例如通过电子邮件发送提交，将其输入数据库。 
 // echo'谢谢。你的消息说''。$ _ POST ['message']。'''; 
 echo<   script  >  alert（' 谢谢。你的消息说.....'）< /   script  > ; 
 echo<   script    类型  ='  text / javascript' >  
 alert（' 。json_encode （$ _SESSION [' security_code ' ]）。'）; 
 <   /   script  > ; 
 unset（$ _ SESSION ['security_code']）; 
} else {
 //在此处插入您的代码以显示错误消息
 echo'抱歉，您提供了无效的安全代码'; 
 echo<   script  >  alert（' 抱歉，您提供了无效的安全码'）< /   script  > ; 
} 
}其他{

 <   tr  >

i想在我的java脚本代码中使用此会话值

  function  form_validation（）
 {
 hh = 文档 .WebToLeadForm; 
  if （！hh.security_code.value ==  ）{
  var  a =<？php echo $ _SESSION ['   security_code']; ??> 
 alert（ 请等待检查匹配）; 
  return   false ; 
} 

i使用代码但无法正常工作可以弄清楚如何使用..

Hi,
Friends i have a code

<?php <br mode="hold" /?>session_start();

if( isset($_POST['Submit'])) {
   if( $_SESSION['security_code'] == $_POST['security_code'] && !empty($_SESSION['security_code'] ) ) {
		// Insert you code for processing the form here, e.g emailing the submission, entering it into a database. 
		//echo 'Thank you. Your message said "'.$_POST['message'].'"';
		echo "<script>alert('Thank you. Your message said.....')</script>";
		echo "<script type='text/javascript'>
    alert('".json_encode($_SESSION['security_code'])."');
</script>";
		unset($_SESSION['security_code']);
   } else {
		// Insert your code for showing an error message here
		echo 'Sorry, you have provided an invalid security code';
		echo "<script>alert('Sorry, you have provided an invalid security code')</script>";
   }
} else {
?>
<tr>
                        <td height="50" valign="top"> </td>
                        <td valign="top"><img src="CaptchaSecurityImages.php?width=100&height=40&characters=5" /></td>
                      </tr>
<tr>
                        <td height="30" valign="top">Security Code:<span class="required" style="color:#93B928;">*</span></td>
                        <td valign="top"><input id="security_code" name="security_code" type="text" style="width:100px;"/></td>
                      </tr>
                       <tr>
