Answer 1

the variable $site_key is not defined, and you are attempting to test if it returns a true value in your If statement ( which it doesen't, since it is not even defined )

To check wether or not a variabel is defined, use the isset function call, then you can check if it's value is true.

if( isset( $site_key )  and $site_key )
{
  line                 
                      <div class="form-group">
                          <div class="col-sm-offset-2 col-sm-10">
                              <div class="g-recaptcha" data-sitekey="<?php echo $site_key; ?>"></div>
                              <?php if ($error_captcha) { ?>
                              <div class="text-danger"><?php echo $error_captcha; ?></div>
                              <?php } ?>
                          </div>
                      </div>
}
