If you are wanting to stop people from registering with PO Box based addresses in Opencart 1.5.x then you need to make some modifications to a few key files. The process is very straight forward and should not take long to complete.
Preventing spam sign ups on RSMail can only be done using captcha. There is no actual backup solution if you do not wish to use the RSMail module without captcha. The most common thing with spammers is that they usually spam from one IP not multiples. To prevent them from spamming I have developed a simple IP checker. RSMail has a field from storing IP's in the Joomla Database. The solution I have developed simply checks to see if the person submitting the information has already submitted an email address. While I realise this is probably a bad solution for those who are using their office connection to sign up I am not going to even cater for those people. Use your home internet or mobile phones data plan.
While working on a website for a client just a couple weeks back I found an issue where I wanted to make it easier for the client to add and edit images in a particular module with particular attributes to have particular formatting / styling from CSS applied to it. While the first thought was keep it simple I soon came to the realisation that the issue is a lot more complex than first thought.
If you are wanting to use custom fonts in websites this is possible by using the following code:
Keep in mind that good old Internet Explorer fails the test when using the above code so you have to convert the fonts to another format (EOF) and then create a custom css file for IE which contains the following:
@font-face {
font-family: fontname;
src: url('../fonts/fontname.eot');
}
Once you have that you can then start referencing the font name in your CSS. This is a really cool feature but not all browsers support this as yet. Give it a go and I am sure you will be most impressed with the outcome.
Getting a footer to go the full width of a screen is a painful exercise if you have never done it or have only done it a few times. After doing a lot of searching on the internet for a div and css solution followed by 2 hours of playing around I have found one that works in all browsers including Internet Explorer, FireFox and Safari. It is CSS 2.0 compliant code so it may not work on older browsers.
