我如何保持php表单过程脚本不被单独处理，而不从其html页面调用？

Question

I've been ask to troubleshoot a problem on a very, very old html website which I did not build. There are two html forms which each call their own php scripts to process them. They have been getting empty form submissions. I put code in place to make three of the fields mandatory as well as added a captcha form. When you go through the normal process, these measures work to stop empty form submissions. However, they are still getting empty form submissions. I discovered that if you enter the script url directly in a browser, for example form-process.php, it does submit the empty form without the mandatory fields nor the captcha.

Any suggestions on keeping this script from running on it's own?

Thank you in advance. PS, I am a php novice, so the php for dummies version would be appreciated.

Answer 1

You can do two things (either or and)

1. Use htaccess to stop users from running it
2. If the mandatory fields are not there, then don't save the form. Just check and stop execution on the first line.
