How would I get this php code to validate the phone number before sending?

 

Write here what type of phone numbers you consider as valid phone numbers.

 

anything XXX-XXX-XXXX or XXX XXX XXXX (hyphens dont really matter if they are there or not)

 

You need to list each unique property of a valid phone number, then test your phone number variable for those properties using php.

With what you have so far, these are the properties I see:

1. 12 characters in length.
2. 4th and 8th characters are spaces or hyphens.

Both of those are trivially easy to test for in php. However, I think you need to think about your properties more--see if you can create an invalid phone number that has all your properties.

Is 123-abc-@#$% a valid phone number? If not, then you need to define and check for invalid characters.
Is 7128675309 a valid phone number even though its only 10 characters long? If so, refine properties #1 & #2.
Is 712.867.5309 a valid phone number even though it uses periods? If so, refine property #2.

Keep trying to break your properties with invalid phone numbers until your properties are satisfactory and then code a test for each property in php.

 

class phoneNumber {
    public $nums;
    
    function __construct($num) {
        $this->set($num);
    }
    
    function set($num) {
        $num = preg_split('//', $num);
        foreach ($num as $key => $value) if (!is_numeric($value)) unset($num[$key]);
        
        if (count($num) < 10 OR count($num) > 11) {
            trigger_error("WOOPS! The phone number is not valid. The length ".count($num)." isn't enough.");
            exit;
        }
        
        $num = array_merge(array(), $num);
        $this->nums = $num;
    }
    
    function get() {
        $nums = $this->nums;
        if (count($nums) == 11) {
            $num = $nums[1].$nums[2].$nums[3]."-".$nums[4].$nums[5].$nums[6]."-".$nums[7].$nums[8].$nums[9].$nums[10];
        } else if (count($nums) == 10) {
            $num = $nums[0].$nums[1].$nums[2]."-".$nums[3].$nums[4].$nums[5]."-".$nums[6].$nums[7].$nums[8].$nums[9];
        }
        return $num;
    }
}

PHP:

I just wrot ethis class for 'ya. Here's the usage:

$somePhoneNumber = "1 234 567 8901"
$pn = new phoneNumber($somePhoneNumber);
echo $pn->get();

PHP:

All it does is store all the numbers inside the input into an array. If the array isn't the right size for a phone number (10 or 11), then it uses trigger_error() to show an error message. The get() function displays the formatted phone number which is just the array formatted as a phone number.

 

Nice! Thanks!

Now umm how do i go about adding that to my code? Sorry kinda a php newbie here...

Thanks though that's awesome!!!

 

Just add the class declaration somewhere above the code. In a global file if possible.

Then you can text a phone number by storing whatever you want to test in $somePhoneNumber , then testing it with:

$pn = new phoneNumber($somePhoneNumber);
$result = $pn->get();

Code (markup):

$result is what you should actually add to your database. $result stores the properly formatted phone number. The script formats all phone numbers the same way so that everything will be consistent.
