title: php+jquery+captcha, is this is the correct way?
body: <p>I am using combination of php+jQuery for captcha validation and later sending mails and do other stuff. The pseudo code is something like this:</p>
  
  <pre><code>captcha_code = jQuery.post(.....execute captcha script and get status)
  if(captcha_code == "correct"){
      send_mail_using_php_script;
  }
  </code></pre>
  
  <p>Now I have no idea whether spammers can directly execute the "send_mail_using_php_script". Do they? If yes, then shall I move captcha validation in send_mail_using_php_script to make it more safer? Is there any other safer method?</p>
