Submitted messages are sent to a specified email address using SMTP with support for SSL or TLS transport. 15 | 16 | **A Note On Security:** [PHPMailer](https://github.com/PHPMailer/PHPMailer), which this contact form is dependent on, had a major security vulnerability fixed in 5.2.20. **It is recommended to update to 1.4.** 17 | 18 | ## Version History 19 | 20 | | Versions | Major Enhancement | 21 | | -------- | ----------------- | 22 | | 1.4.1 | Bumped [PHPMailer](https://github.com/PHPMailer/PHPMailer) version to 5.2.21. | 23 | | 1.4 | Add support for [cURL](http://php.net/manual/en/book.curl.php) when POSTing to verify reCAPTCHA. | 24 | | 1.3 | Add support for [Bootstrap Validator](https://github.com/1000hz/bootstrap-validator). If provided, will use it to validate contact form. | 25 | | 1.2 | Replaced PHP SecureImage Captcha with Google's reCAPTCHA. | 26 | | 1.1 | Used PHPMailer. Support for SSL/TLS transport. Extracted configuration values to environment variables. | 27 | | 1.0 | First Version - Used PHP SecureImage and PHP mail function | 28 | 29 | ## Dependencies 30 | 31 | ### PHP 32 | * version > 5.2.0 33 | * [PHPMailer](https://github.com/PHPMailer/PHPMailer) (included in [library/vender/php_mailer/**](https://github.com/jonmbake/bootstrap3-contact-form/tree/master/library/vender/php_mailer)) 34 | 35 | ### HTML/JS 36 | * [Bootstrap 3](https://github.com/twbs/bootstrap) version >3.1 37 | * jQuery 38 | * **Optional** [International Telephone Input](https://github.com/Bluefieldscom/intl-tel-input) (included in [assets/vender/intl-tel-input/**](https://github.com/jonmbake/bootstrap3-contact-form/tree/master/assets/vender/intl-tel-input))- This is used to validate and format the phone input field. Only need this if the phone field is present. 39 | 40 | ## Setting up reCAPTCHA 41 | 42 | You must obtain a [Site Key and Secret Key from Google](http://www.google.com/recaptcha/admin). The *Site Key* must be entered into the [Contact Form HTML](https://github.com/jonmbake/bootstrap3-contact-form/blob/master/index.html) in the place of the text *your_site_key*. The *Secret Key* should be entered as a configuration value (see next section). 43 | 44 | **Note:** Many web servers now force `allow_url_fopen=0` and `allow_url_include=0` due to security concerns (see: [Issue 26](https://github.com/jonmbake/bootstrap3-contact-form/issues/26)). reCAPTCHA verifying will use [cURL](http://php.net/manual/en/book.curl.php) is if it is installed. If you are having issues verifying reCAPTCHA, most likely you need to install [cURL](http://php.net/manual/en/book.curl.php). 45 | 46 | ## Configuration 47 | 48 | Configuration values to the contact form are passed in via *Environment Variables*. The following variables need to be defined: 49 | 50 | | Name | Description | 51 | |-------------------- | -------------------------------------------------------------------- | 52 | | FEEDBACK_HOSTNAME | Host name for SMTP server | 53 | | FEEDBACK_EMAIL | Email address to authenticate to SMTP server with | 54 | | FEEDBACK_PASSWORD | Password to authenticate to SMTP server with | 55 | | FEEDBACK_ENCRYPTION | If specified will use encryption. Valid values: TLS or SSL | 56 | | RECAPTCHA_SECRET_KEY | reCAPTCHA secret key. | 57 | | FEEDBACK_SKIP_AUTH | **Optional** If specified, will not authenticate with email/password | 58 | 59 | Environment variables can be specified in a variety of ways. For example, if using *Apache* (and *mod_env* is enabled), they can be specified in *.htaccess*: 60 | 61 | ``` 62 | SetEnv FEEDBACK_HOSTNAME smtp.gmail.com 63 | SetEnv FEEDBACK_EMAIL me@gmail.com 64 | SetEnv FEEDBACK_PASSWORD my!password! 65 | SetEnv FEEDBACK_ENCRYPTION TLS 66 | SetEnv RECAPTCHA_SECRET_KEY 7823skdgjksd828sjdgkn 67 | ``` 68 | 69 | **Tip:** *Environment Variables* are used in [Sendmail.php](https://github.com/jonmbake/bootstrap3-contact-form/blob/master/library/sendmail.php). **If you don't want to use Environment Variables**, you can edit *sendmail.php*, replacing calls to #getenv with the corresponding configuration value like in this [Example Gist](https://gist.github.com/jonmbake/0e5b175a72ad9ba64167). 70 | 71 | ## What If I Don't Want CAPTCHA? 72 | 73 | There's a branch for that!
