Just a quick post before I leave. During the holiday season, I managed to study some regular expression and come up with few lessons learned. A good start for a regex newbie like me.
Creating code name from text
I’m creating a simple store application and I want to create automatically an item code based on the given item name (only when the user does not enter a code). Here is the regex:
preg_replace('/[^-a-zA-Z0-9]/', '', $name);
Simple amount validation
I need to validate the entered price which needs to be numeric or with two decimal places via JavaScript. Here us the regex:
^[0-9]+(\.[0-9][0-9])?$ # which will match dddd.dd or dddd
That’s it for now.
thanks for your post, very helpful for a n00b on regex here. I have applied your simple amount validation on my text field in my flash app. I’ll be a regex newbie forever until a project comes up that will use this extensively =P
Thanks for dropping by gensourai23. Haven’t done any heavy regex yet so that’s just it for now.
