HTML PHP Contact Form - Submit and Message Issues.

Quick Start

PHP Contact Form With Captcha. Preview the form Download. This is a contact form with the essential fields like name, email and a message field. The form is built on top of bootstrap framework. Bootstrap makes the styling easy and quick. The sections below explain the code of this form The HTML Code.

After you've signed up for your API keys, below are basic instructions for installing reCAPTCHA on your site. A fullreference guide to the PHP plugin can be found below.

Client Side (How to make the CAPTCHA image show up)

If you want to use the PHP library to display the reCAPTCHA widget, you'll need to insertthis snippet of code inside the <form> element where the reCAPTCHA widget will beplaced:

With the code, your form might look something like this:

Don't forget to set $publickey by replacing your_public_key withyour API public key.

Note that the value of the 'action' attribute is 'verify.php'. Now, verify.php is thedestination file in which the values of this form are submitted to. So you will need a fileverify.php in the same location as the client html.

The require_once function in the example above expects recaptchalib.php to be in the samedirectory as your form file. If it is in another directory, you must link it appropriately.For example if your recaptchalib.php is in the directory called 'captcha' that is on the samelevel as your form file, the function will look like this:require_once('captcha/recaptchalib.php').

Server Side (How to test if the user entered the right answer)

The following code should be placed at the top of the verify.php file:

In the code above:

  • recaptcha_check_answer returns an object that represents whether the usersuccessfully completed the challenge.
  • If $resp->is_valid is true then the captcha challenge was correctly completed and you should continue with form processing.
  • If $resp->is_valid is false then the user failed to provide the correct captchatext and you should redisplay the form to allow them another attempt. In this case$resp->error will be an error code that can be provided to recaptcha_get_html.Passing the error code makes the reCAPTCHA control display a message explaining that the userentered the text incorrectly and should try again.
    • Form

    Notice that this code is asking for the private key, which should not be confusedwith the public key. You get that from the same page as the public key.

    Also make sure your form is set to get the form variables using $_POST, instead of$_REQUEST, and that the form itself is using the POST method.

    That's it! reCAPTCHA should now be working on your site.

    I am looking for a simple HTML for a contact form that has ReCaptcha or some type of anti-spam features. I tried multiple tutorials but they are all complicated and I can't get any to work. All I need is an Name, Email, and Message field (and also the ReCaptcha and submit button). Does anyone know where I can find a simple contact form HTML?
