ereg help

[chrisuk]

if i have say..

 

if (!ereg ("[A-Z][a-z]", $surname ))

 

it wont take an input such as £"$£%, or 998943

 

BUT, if you do say 9Joe88, or $%Harry^...it gets accepted

 

Why is that happening?

 

thanks

What are you trying to accomplish? The reason the first one fails is that it does not contain ANY of the characters you specified. The way you have written the regex, the string must contain at least ONE of the characters you have specified. I am assuming you are wanting to limit the user to ONLY entering the characters specified:

 

if (eregi ("[^a-z]", $surname )) { echo "Invalid"; }

else { echo "Valid"; }

Thanks

 

yes that is what I am trying to do

 

I have done as you suggested, but it only works if i enter say John Smith, and not john smith...which is odd?

You need to post your code, I don't think you followed my example correctly. You are probably not using eregi as I did in my example! ereg is case sensitive, eregi is not. Plus, did you change the test from a false test to a positive test? Lastly, if you want to include spaces in the name then you need to add a space to the test as well.

 

if (eregi ("[^a-z ]", $surname )) { echo "Invalid"; }

else { echo "Valid"; }

Ahh, i forgot to make it a positive

 

working properly now, thanks
