Re: Re: [PHP-DB] Re: [PHP] Regex for telephone numbers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Why not have three separate fields for each part, as that way you don't need to bother about how the user separates them, as trust me, if they can break it, they will. I have found it is best to always limit the amount of free entry you permit a user, as that will drastically cut back in data entry validation.

Hi Ethan,
Could you do a string compare and check at certain characters for a dash?
IE:
check the second character to see if it is a dash for 1-800...
if that is not a dash, check the fourth character for a dash, 469-9...
then the other places where dashes would be based on those two characters.
You may have to investigate how international numbers would work and
adjust appropriately, but for the US, that should work.
Then just send an error message when it isn't like you want.

Dear List -

Thank you for all your help in the past.

Here is another one....

I would like to have a regex which would validate that a telephone
number is in the format xxx-xxx-xxxx.

Thanks.

You can't, phone numbers are more complex then that. You could use
\d{3}-\d{3}-\d{4} to match that basic pattern for all numbers though.
