[RESOLVED] ereg blank

plapeyre

how do i incorporate the allowance for an empty field into this..

(!ereg("[0-9]",$phone_home)) {

thankyou

I'm assuming that an empty field would create an "else" statement:

if(!empty($phone_home)){
(!ereg("[0-9]",$phone_home)) {
}

}
else{do something since it's blank }

For something like a phone number, I prefer not to force the user to input a specific format, but let them enter it with parens, dashes, and or spaces if they want, then strip out the non-numeric characters before storing it:

$phone = preg_replace('/\D/', '', $phone_home);

Now if you want, you can validate $phone to see if it's an empty string, if it has some exact number of digits, or a number of digits between x and y, etc.; but you'll know it contains only digits (or is blank) at this point.

I've always preferred to use 3 TEXT boxes (Area Code, Next 3 Numbers, Last 4 digits) for each phone number. Simple to check and add together.

Of course, you have to know your audience, but in my case it is 100% used by US folks...

Why leave anything up to chance. Make it as dummy proof as possible.

Good luck!

yeah i was thinkin of ragedigitals idea..
what i have is basically.. a working code saying 'you need to choose atleast 1 of the three contact methods, home, work mobile/cell...' ... so they either type it in correctly (10 digits here in australia including area code) or they can write in nothing.. i already have the relevant code if they have nothing in all three.. so that isnt the problem.. .this is just a statement to say either "just numbers" or "nothing"

thankyou

kk i was thinking...

if ((empty($phone_home)) || (!ereg("[0-9]",$phone_home))) { ...

that should be fine, right? (havent opened up phpdesigner yet.. but im getting there)

plapeyre

sorry to spam.. i just re-read what i posted, that wont work..
any suggestions?

pseudo time!

if the field is blank or DOES use chars 0-9, its okay, else it's an error...

there will be no need for spaces etc..

ragedigital

Can't you just remove the "!" out of your ereg statement?

plapeyre

no because it has to allow "nothing" aswell...

or will that allow 0-9 and empty

plapeyre

    elseif ((!$phone_home) && (!$phone_work) && (!$phone_mobile)) {
        $error = 'At least <u>ONE</u> contact number is required.';
        $show_modifyform = TRUE; }
    elseif (!ereg("[0-9]",$phone_home)) {
        $error = 'Not a valid phone number';
        $show_modifyform = TRUE; }

ragedigital

This should work for a statement that would be - either empty or match 10 digits:

if ((empty($phone_home)) || (ereg("^([0-9]{10})$",$phone_home)))

plapeyre

fantastic.. i didnt even think of it that way 🙂 IT WORKS:

elseif (((empty($phone_home)) || (ereg("[0-9]{10,10}",$phone_home))) && ((empty($phone_work)) || (ereg("[0-9]{10,10}",$phone_work))) && ((empty($phone_mobile)) || (ereg("[0-9]{10,10}",$phone_mobile))))  { ...
