简单的验证码会话问题
我在验证码图像和会话变量方面遇到了一个非常荒谬的问题。
http://paholo.com/npdev/tests/contact_us2 .php?add=1&confirm=new#contact
我已经多次使用过同样的“联系我们”脚本，但显然现在有些问题了。当我在脚本内运行 make_captcha.php 时，它只是不会存储 $_session['captchacode']。
但是当我在脚本之外运行它时，它工作正常。
我在 make_captcha.php 和 contact_us2.php 脚本上都有 session_start() 。
我知道这里有一个简单的答案，但我就是看不到。
<?php session_start(); ?>

I've got a quite ridiculous problem with a captcha image and session variable.
http://paholo.com/npdev/tests/contact_us2.php?add=1&confirm=new#contact
I've used this same "Contact us" script numerous other times but clearly something is now off with it. It just won't store the $_session['captchacode'] when I run the make_captcha.php inside the script.
But when I run it outside the script it works fine.
I have session_start() on both themake_captcha.php and the contact_us2.php script.
I know there is a simple answer here but I just can't see it.
<?php session_start(); ?>
