This deserves more likes and more views. Reg Expressions can be a pain to beginners and stack overflow cant explain like you do. Awesome man. Clean and understandable thanks for the effort. I loved it.
@@clevertechie hi newb here, so the only way to force users to only enter [0-9] and not with commas, periods in textbox is using regex? otherwise, echo error input. I tried, strpos, strpbrk and other string manipulation but no luck. hope you can clear things up a bit. coz I want ProductCode to only accept [0-9] as inputs.
I have been watching your tutorials and I got to say you are "KILLING IT!". From all the videos I enjoyed yours. All other youtubers that provide tutorials doesn't have anything on you. I go to some of the videos and I am left disappointed. You have put a lot of work into them. It reminds me of me when I was with Instinet, IBM, Microsft, etc when I would create handbooks with a lot of details and images. Keep up the go work. Sometimes I don't have time to go through a PHP book and your videos on the subject speeds my learning process. You videos and a good book helps my learning. I especially love the 100 PHP functions series. I let your videos run all day, like someone does for music. This way it can go into the sub-conscience mind.
