At one point or another, while developing a backend admin section, the client will ask for the ability to change the color of something. Be it text, backgrounds, or you just want to add this ability to your next project, this tutorial will demonstrate an easy way to create a dynamic color picker, that when a color is picked, it will automaticly insert that value into the desired form field. See demo here.
Before we begin, you will need to download thetransperent gif below.

For this tutorial we will only need two CFM files. One file will contain the form elements, and the other will be the pop-up color picker. Below is the code for the form.cfm
|
FORM.CFM <!DOCTYPE
html public "-//W3C//DTD HTML 4.0 Transitional//EN"> |
The main thing to be awaer of here is in the javascript function. I bolded the the important area above.
FORMFIELD= Whatever your form is called. VERY IMPORTANT. if theses fields are not the same, it will not work.
.ColorValue This is the field you want to target. You can have several of these color pickers on your page but this field needs to be unique to the form field you are wanting to change.
|
<CFPARAM
name="show" default="Other"> <!---
It's worth moting here. The color values you see below are on different
lines for visual refrence only. <CFSET
TheColors = "000000,111111,222222,333333,444444,555555,666666, <CFSET
TheCount = 0>
|
Thats it. Just go to form.cfm,
and test it out.

Banning the spam
Internet spam is on the rise, and more importantly spammers are targeting your sites comment forms. They are looking for the trackback urls to fool search engines into ranking their website higher in the search results. When this started to happen to me, I wanted to sent out emails to the offenders demanding that they stop. Unfortunatly the spam is being generated by bots and programs not some pimple faced kid behind a keyboard. Banning IP addresses is not enough and rarely works since intelligent spammers hide their true identity anyway. Next approach... Banning Keywords used by the offending sites. Thats where this tutorial comes in.

Improving Application Performance
One thing I am always trying to do is speed up my applications. As my site grows in size and complexity I find that I spend a fair amount of time re-coding pages because of a new technique I just learned. I wish I had learned about these techniques long before, and thereby allowing me to create more effective code. In this tutorial I'll try to explain some problem areas that I have identified, and some of the things you can do to improve performance.

Query Caching is another way to save data and eliminate unnecessary queries. This is for queries that are more dynamic in nature.

Slighty better search
Someone on the forum posed a question a short while ago asking how to create a more advanced search function using a + symbol as a separator. So I created this advanced search function. This search function is just slightly better than a normal search as it adds the ability to separate two keywords with a + symbol. Lets start with the search form.
