Is it possible to link WP Domain Checker Buy Button / Purchase Button to Contact Form 7? This is a question from one of WP Domain Checker user.

The answer is YES. It is possible!

We can use HTTP GET variables feature from Contact Form 7.

To get the default value from HTTP GET variables, add default:get option to the form-tag

For example, you have a field with a name “domain” in Contact Form 7:

[text* your-name]

Then, just add default:get

[text* domain default:get]

The field will obtain its default value from the GET variable with the same name (“domain”).

In WP Domain Checker settings, set integration to Custom URL and fill the Custom URL with your Page URL where Contact Form 7 placed and add ?domain={domain} in the end of url.

For example, your Contact Form URL is https://example.com/contact/

Add ?domain={domain} to end of url become https://example.com/contact/?domain={domain}

WP Domain Checker WordPress Plugin have feature allow you to check Internationalized Domain Name (IDN), to make this plugin able check IDN domain, you need enable/install Intl php extension. There are several method to install/enable this extension:

Installing on Linux (Ubuntu)

run the following commands:
sudo apt-get install php5-intl

You then need to restart Apache
sudo service apache2 restart

You can also check what extensions are compiled in by running:
php -m

Installing on Linux (Centos)

run the following commands:
sudo yum install libicu

sudo yum install libicu-devel.x86_64

sudo /usr/bin/pecl install intl

add “extension=intl.so” in your php.ini file.

You can also check what extensions are compiled in by running:
php -m

Installing on OSX

1. Install ICU Libraries with Homebrew

The ICU Libraries is our only dependency. If you have Homebrew installed you can use that; alternatively, you can download and compile from source.

Using homebrew:

brew update

brew install icu4c

2. Install Intl with PECL

sudo pecl update-channels

sudo pecl install intl

and add “extension=intl.so” in your php.ini file.

restart the apache.

if you found this error:
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

The solution I came up with was to compile autoconf from source and set the environment variable which points to autoconf required by phpize.

Download autoconf
curl http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz > autoconf.tar.gz

Untar the autoconf archive
tar -xvzf autoconf.tar.gz

Configure and make – note the folder un-archived may have a different name.
cd autoconf-2.69
./configure
sudo make && sudo make install

This installs autoconf to ‘/usr/local/bin/autoconf’. In order to get phpize to work set the PHP_AUTOCONF environment variable to point to the newly installed autoconf.

export PHP_AUTOCONF=/usr/local/bin/autoconf

Running phpize when attempting to compile a php extension should now work.
