I want to validate Email or Mobile via PHP validation with preg with single input and Mobile starts only 7,8 & 9 and only should be 10 digit. How can i validate this only in PHP.

Answer 1

For javascript

function validateEmail() {
    var email = document.getElementById('txtEmail');
    var mailFormat = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})|([0-9]{10})+$/;
    if (email.value == "") {
        alert( "  Please enter your Email or Phone Number  ");
    }
    else if (!mailFormat.test(email.value)) {
        alert( "  Email Address / Phone number is not valid, Please provide a valid Email or phone number ");
        return false;
    }
    else {
        alert(" Success ");
    }
}

Use this Regular Expression with Node JS

/^([_a-z0-9]+(.[_a-z0-9]+)@[a-z0-9-]+(.[a-z0-9-]+)(.[a-z]{2,5}))|(\d+$)$/
