so how do you come up with that code? //check if hidden value was used if(isset($_POST['secret']) && trim($_POST['secret']) !=''){ die('Hidden value was used'); } from this code I dont see how you got the word isset what does it do? and how did you get to know to use it here? and how does trim make it die? when i see the word trim i think its just going to cut some of the words and not all of them. and how do you know when to use !=" and all these brackets {}][. is there a simple code to php like: if this contains this. do this. or check this depending on the answer do this or this....\ does that make any sense? im just trying to grasp the concept of php

I want a website to have a form that DOES NOT use captha but I get alot of spam. I want to use a couple of methods that will not deter the user. My methods are honeypot technique(hidden form) and not submitting form if contain certain words. I want to use is a hidden field that if a spam bot fills out it will disregard the form the spam bot will think the form was submited but it will actually disappear into the abyss . if the form contains www. or .com or http:// or armani,Pharmacy,Viagra... you get the idea . it will not submit the form but will still take you to the thank you page
