[SOLVED] php + javascript

[phorcon3]

i need this one function which should be written in php and javascript

 

php:

$text = $_POST['text'];

 

javascript:

var text = document.getElementById('text').value;

 

so, "text":

 

1) may contain a-zA-Z0-9 as well as a period "."

2) first letter must be alphanumeric, so ".text" would result in an error

3) there should be no consecutive periods allowed, so "text..text" would result in an error

4) last letter must be alphanumeric as well, so "text." would also result in an error

 

does anyone know how to do this with just on line of code (regex) in both, php and javascript?

 

thanks in advance

This should cover 1, 2 and 4. Probably not the best approach, I'm some somebody will do better but it's a start. I have no idea how you'd check that there are no double fullstops.

 

"~^[a-zA-Z][a-zA-Z0-9\.]+?[a-zA-Z]$~"
