I'm making a contact search page. The search criteria are Name, Phone Number and Email. I'm trying to attempt the following logic.

• SearchContacts is pressed
• Checks for Blank Fields
• Validate input(Name,Phone,Email)
• Search Contacts for matches
• Generate Contact table with results

My current problem is that I have 3 Input Validation methods and not sure how to call their results into my "Search Contacts" function. Could someone provide me a solution on how to do this?


Here are the validation functions: 

/* Name Input Validation Regex*/
   public static Boolean ValidationName (String name)
            {
                Boolean NameIsValid = false;
                
              
                String nameRegex = '/^[a-zA-Z][a-zA-Z0-9]*(_[a-zA-Z0-9]+)*(__[cC])?$/';
                Pattern PatternName = Pattern.compile(nameRegex);
                Matcher nameMatcher = PatternName.matcher(name);
                
                if (!nameMatcher.matches()) 
                    
                NameIsValid = true;
                return NameIsValid; 
            }
    
     
    /* Phone Input Validation Regex*/
    public static Boolean ValidationPhone (String phone)
            {
                Boolean PhoneIsValid = false;
                
               
                String phoneRegex = '//^\\(?([0-9]{3})\\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$//';
                Pattern PatternPhone = Pattern.compile(phoneRegex);
                Matcher phoneMatcher = PatternPhone.matcher(phone);
                
                if (!phoneMatcher.matches()) 
                   
                PhoneIsValid = true;
                return PhoneIsValid;        
            }          
    
   
     /* Email Input Validation Regex*/
     public static Boolean ValidationEmail (String email)
            {
                Boolean EmailIsValid = false;
                
               
                String emailRegex = '/^\\w+([\\.-]?\\w+)*@\\w+([\\.-]?\\w+ (\\.\\w{2,3})+$//';
                Pattern PatternEmail = Pattern.compile(emailRegex);
                Matcher emailMatcher = PatternEmail.matcher(email);
                
                if (!emailMatcher.matches()) 
                    
                EmailIsValid = true;
                return EmailIsValid;    
            } 


And here is the method I want to call those results into: 
public PageReference searchContacts()
        {
                           
            
            
              /* Checks if input fields are empty*/
            if (name == '' || phone == '' || email == '')
                {
                    Error_FieldsEmpty = true;   
                    ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,'One or more of your fields are blank. Please enter your information in the remainding fields to proceed'));
                }         
            else 
            {
                /* Check Validations*/
                
                
                
                
            }
