Check for mobile number CF7 - php

Question

I have a ContactForm7 form which submits data to a CRM. All works fine but now I need to differentiate between mobile and landline numbers. If a number starts with 07 it will be accepted as a mobile number.
looking at other threads I've tried the following but now neither the mobile or telephone field are being populated in the crm or being passed to the log file?
function process_contact_form_data( $contact_form ) {
$title = $contact_form->title;
$submission = WPCF7_Submission::get_instance();
if ( $submission ) {
$posted_data = $submission->get_posted_data();
}
if ( 'Quote Form_Contact' || 'Quote Form_Product' || 'Quote Form' == $title ) {
$firstName = $posted_data['user_first_name'];
$lastName = $posted_data['user_last_name'];
$email= $posted_data['your-email'];
$phone = $posted_data['your-number'];
$message = $posted_data['your-message'];
$bp = $posted_data['BP'][0];
$phone = $pattern;
$pattern = "/^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/";
$match = preg_match($pattern,$phone);
if ($match != false) {$mobile = $phone;} else {$mobile= '';};
}
$error = false;
try
{
$relationshipId = postRelationship($firstName,$lastName,$email,$phone,$bp);
$opportunityId = postOpportunity($relationshipId,$message);
postOpportunityNote($relationshipId,$opportunityId,$message);
// postTask($relationshipId);
}
catch (Exception $e)
{
$error=true;
}
if($error || !isset($relationshipId) || !isset($opportunityId) || $relationshipId <= 0 || $opportunityId <= 0)
{
$log->lfile(ABSPATH . 'quotevine.log');
$log->lwrite('ERROR: With Email Address ' . $email);
$log->lclose();
}
}
add_action( 'wpcf7_before_send_mail', 'process_contact_form_data');

Answer 1

Your are overwriting your $phone variable in this line $phone = $pattern; with an undefined variable which will cause $phone to be NULL.
But after commenting out that line, the value of $mobile will still not be correct because a mobile number starts with 07 and the regex matches both the landline and the mobile number, for example:
07123123123
[phone]
What you could do is if the match succeeded, check if the string starts with +44 to verify it is a mobile number.
preg_match returns false if an error occurred but I think you want to verify if the match is correct.
$phone = "[phone]";
$pattern = "/^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/";
$mobile= '';
if (preg_match($pattern,$phone) && 0 === strpos($phone, '07')) {
$mobile = $phone;
}

Answer 2

You overwrite the phone with an undefined variable.
// Phone is now a phone number I assume
$phone = $posted_data['your-number'];
$message = $posted_data['your-message'];
$bp = $posted_data['BP'][0];
// $pattern is as far as I can see undefined
// $phone =NULL
$phone = $pattern;
// You set pattern
$pattern = "/^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/";
// Here you regex if the pattern matches NULL which it does not.
$match = preg_match($pattern,$phone);
