This article mainly introduces how to solve the phpcms background login verification code can not show the problem, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

During the phpcms v9 move, we made a background login in the new space, but found that the background CAPTCHA was not displayed. We used the win host. We know that CAPTCHA generates pictures directly, while in PHP, we must open the gd library to use the picture CAPTCHA. After checking the win host, we really didn't open the gd library and found it under php.ini. Search for extension=php_gd2.dll and remove the previous comment semicolon.

Check that the profile site path is correct

Sometimes during the move, we move the entire site to the blog file in the root directory of the website. At this time, we need to change the directory path of the website, otherwise the verification code will not be displayed. Open the configuration file cache/configs/system.php and look for the following code:

/ / website path 'web_path' = >' / the path where the website is located /'

This is the path to the site installation, which usually defaults to 'web_path' = >' /', but if we change the site directory, such as moving under blog/, we need to set it to 'web_path' = >' / blog/', to be correct.

Check the encoding format of the configuration file

For the coding format problem is actually after our secondary development caused by the verification code does not show the problem, this kind of problem is very rare, mainly check the cache/configs/system.php and api/checkcode.php file encoding is consistent, such as the version of the program for utf-8 version, in our secondary development when saved into the gb2312 version, this time there will be verification code does not show the problem.
