What is AJAX ? a simple tutorial - Part 1

Ajax is [A]synchronous [J]avaScript [A]nd [X]ML.
Ajax allows you to update a section on your page without having to reload the complete page. You can dynamically check data with a simple set of functions. These functions send data to the server, get a response back and update the page with that information.

I have a test page setup that shows the effects of dynamic updates with data from the server without re-loading the whole page. [ click here for the Online form sample ]

PHP install notes

If you need to install a later version of PHP on a fresh server then you can do so from another repo.

As, in your case php is provided by rh-php56-php-cli, you need to install needed extensions, from the same repository (centos-sclo) and in the same namespace (rh-php56):

yum install rh-php56-php-mbstring

You don`t need to pay £50 - £100 for a certificate, why not get a low cost certificate from 2mx for £20 per year when you host with us.

The need for a secure password

With the amount of hackers and spammers about today you would think that having a reasonably secure password would be the sane thing to do? Having the same password as the username is not very adviseable. It does not take hackers long to break into a system.

Sadly, this has just happened to one of our clients on our server. Unfortunately this affects all users, for this we apologise for mail sending issues.
