Validating contact number in php form - php

I'm trying to validate a contact number in this form (555)555-5555
but it won't work I don't know what is the problem. If I leave it blank it will print the line
"Please fill out your contact number." but if I enter any number not in the specified from. It won't print the error line. Can some one tell me what is the problem?
Thank you.
if (!preg_match( "/^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$/",($_POST['pcnumber'])) && (!empty($_POST['pcnumber']) ))
{
$msg = "pcnumber: $_POST[pcnumber] ";
}
else
{
$pcnumber = NULL;
echo "Please fill out your contact number.";
}

Confirm email field

I am creating a subscribe to us newsletter page, everything else works perfectly fine, but i'm trying to get the user to insert their email twice, the 2nd email field should work as a "confirm email" field. I'm have a little trouble doing so. Could someone lend a land?
If the 2nd email field does not match the 1st email field, it should display an error message
Here is a snippet of the code:
if (trim($fv->txt_Email) == '') {
$e->defineError("email_required", "Please provide your email address.", "txt_Email");
} elseif (!cmsValidation::isValidEmail($fv->txt_Email)) {
$e->defineError("invalid_email", "Please enter a valid email address.", "txt_Email");
}
if (trim($fv->txt_Email2) == '') {
$e->defineError("email_required2", "Please confirm your email Address", "txt_Email2");
} elseif (!cmsValidation::isValidEmail($fv->txt_Email2)) {
$e->defineError("invalid_email", "Please enter a valid email address.", "txt_Email2");
}
You can simply compare the two fields like you do with any other validation check in this code...
if (trim($fv->txt_Email) != trim($fv->txt_Email2)) {
$e->defineError("email_mismatch", "Please ensure your email addresses match", "txt_Email2");
}
if (trim($fv->txt_Email2) != $fv->txt_Email) {
$e->defineError("invalid_email", "Your Email address do not match", "txt_Email2");

How can I give an error if all fields are not filled in?

Basically this is my registration form. I want to make it so if all the fields are not filled in it will give an error. What do I do from here? I would also like to display the error as $msg
<?php
include'db.php';
$msg='';
if (empty($_POST[''])
|| empty($_POST['password'])
|| empty($_POST['repassword'])
|| empty($_POST['user_firstname'])
|| empty($_POST['user_lastname'])
){
// details sent Form
$company=mysql_real_escape_string($_POST['company']);
$address=mysql_real_escape_string($_POST['address']);
$email=mysql_real_escape_string($_POST['email']);
$phone=mysql_real_escape_string($_POST['phone']);
$regex = '/^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/'; //this defines what a valid email should be
if(preg_match($regex, $email))
{
$activation=md5($email.time()); // Encrypted email+timestamp, so randomly generated and unique
$count=mysql_query("SELECT uid FROM preciousmetals WHERE email='$email'") or die(mysql_error());
if(mysql_num_rows($count) < 1)
{
mysql_query("INSERT INTO preciousmetals(company,address,email,phone,activation) VALUES('$company','$address','$email','$phone','$activation');");
// sending email
include 'smtp/Send_Mail.php';
$to=$email;
$subject="Email verification";
$body='Hello, we need to make sure you are human. Please verify your email and get started using your Website account. '.$base_url.''.$activation.'';
Mail($to,$subject,$body);
$msg= "Registration successful, please activate email.";
}
else
{
$msg= '<font color="#cc0000">This email is already in use, please enter a different one.</font>';
}
}
else
{
$msg = '<font color="#cc0000">The email you have entered is invalid, please try again. </font>';
}
}
?>
Thank you for helping out!
Simply do
if (empty($_POST['password']) || empty($_POST['repassword']) || empty($_POST['user_firstname']) || empty($_POST['user_lastname'])){
$msg = 'You have not filled all fiels';
} else {
// details sent Form
......
}
echo $msg;
And also check for filter_var() for email validation its much more nicer than regEx

Processing Contact Form

I am adding a contact page to my website, but having issues with the comment text box. When the user enters invalid information into the name and email text field, the website redirects the user back to the contact page to fill out the correct information. However, I want the comment box to be optional for the user. For example, the user will enter their name and email, but doesn't have any comments. The code should then process the information. Currently, my code will redirect the user back to the contact page because the user did not enter any information into the comment box. Any suggestions on how to fix this error?
Thanks!
if (empty($_REQUEST['comment'])) {
$error = TRUE;
} else {
$comment = $_REQUEST['comment'];
$form['comment'] = $comment;
if (!preg_match("/^.{0,50}$/", $comment)) {
$error = TRUE;
$messages['comment'] = "<p class='errorMessage'> You have entered invalid information.</p>";
} else {
$_SESSION['comment'] = $comment;
}
}
If you want to allow the content box to be empty, just let an empty value be an acceptable value. This means only running your validation against that field if there is a value present. This means removing your if/else statement since empty($_REQUEST['comment']) is no longer a valid check.
if (!empty($comment) && !preg_match("/^.{0,50}$/", $comment)) {
I just added !empty($comment) && to your check which basically says, "if there is a value go ahead and validate it".
One thing you should also do if you use this code is trim whitespace from your comment box values. Otherwise a user could type a space character and that would not be considered empty:
$comment = trim($_REQUEST['comment']);
Final code:
$comment = trim($_REQUEST['comment']);
$form['comment'] = $comment; // I am assuming this is used elsewhere
if (!empty($comment) && !preg_match("/^.{0,50}$/", $comment)) {
$error = TRUE;
$messages['comment'] = "<p class='errorMessage'> You have entered invalid information.</p>";
} else {
$_SESSION['comment'] = $comment;
}

I am using an "If..elseif..else" statement. Email validation

Hi :) This is my first time posting on here but I can't figure it out and it should be simple. I think I have just been looking at it for too long. So I have a form for which I am carrying out form validation, all the validation works and it sends to the database.
The small issue I have is when it comes to the email and confirm email validation, the first if statement checks if the textbox is empty and if it is I should get the "Email is required" message. But due to the second if statement, I think the $emailErr variable gets overwritten by the second error message which should appear only if the email syntax is invalid.
Therefore, if i leave the textbox empty, i still get the "syntax invalid" message rather than the "email is required" message.
My confusion comes from the fact that, for example, my "firstname" validation (and all other validation) is pretty much the same idea but they do not get overwritten by the second error message which is also presented by using a second if statement.
I will copy the code for my firstname validation and the code for my email validation so you can get an idea of what I am talking about. Any help would be greatly appreciated. If not, im sure ill figure it out eventually :) Thanks!
FIRST NAME VALIDATION - if I leave the textbox blank I get error message "First name is required" - which is correct.
//Check if the firstname textbox is empty
if (empty($_POST['fname']))
//Show error message
{
$fnameErr = "First name is required";
}
//Check if fname is set
elseif (isset($_POST['fname']))
//Check the text using the test_input function and assign it to $fname
{$fname = test_input($_POST['fname']);}
//Check if first name contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$fname))
//Show error message & unset the fname variable
{
$fnameErr = "Only letters and white space allowed";
unset($_POST['fname']);
}
else
//Check the text using the test_input function and assign it to $fname
{$fname = test_input($_POST['fname']);}
EMAIL VALIDATION - if I leave the textbox empty I get the error message "Invalid Email Format" - it should be "Email is required" - why is this?
//Check if the email textbox is empty
if (empty($_POST['email']))
//Show error message
{
$emailErr = "Email is required";
}
//Check if email is set
elseif (isset($_POST['email']))
//Check the text using the test_input function and assign it to $email
{$email = test_input($_POST['email']);}
//Check if e-mail syntax is valid
if (!preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/",$email))
//Show error message & unset the email variable
{
$emailErr = "Invalid email format";
unset($_POST['email']);
}
else
//Check the text using the test_input function
{$email = test_input($_POST['email']);}
The proper way to validate an email is by using filter_var
$email = filter_var(filter_var($_POST['email'],FILTER_SANITIZE_EMAIL),FILTER_VALIDATE_EMAIL)
if(!$email)
$invalidemailMessage = 'You have entered an invalid email address!';
End of story.
If you really,really,really need to output "Email required":
if($_POST['email'] == "" || preg_match('/^\s+$/', $_POST['email']) == true) {
$invalidemailMessage = 'Email required.';
} else {
$email = filter_var(filter_var($_POST['email'],FILTER_SANITIZE_EMAIL),FILTER_VALIDATE_EMAIL)
if(!$email)
$invalidemailMessage = 'You have entered an invalid email address!';
}
with some adjustment to your current code you can keep it, ALTHOUGH what #tftd said is absolutely correct with regard to Sanitisation and Validation.
$error = array();
if (empty($_POST['email'])) {
$error[__LINE__] = "Email is required";
} elseif (isset($_POST['email'])) {
$email = test_input($_POST['email']);
}
if (!preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/", $email)) {
$error[__LINE__] = "Invalid email format";
unset($_POST['email']);
} else {
$email = test_input($_POST['email']);
}
if ($error){
print_r($error);
}
Part of your problem with your code is your last if is still being ran so you will always get the error if the email field is empty.
Change this
if (!preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/",$email))
To this
if (isset($email) && !preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/",$email))

See if # symbol is in field and proceed with form validation

I am trying to set up a web form for my website and I want to search the user's input for an # symbol and if it is not there, the form should not validate and a message should show up asking the user to recomplete the form.
Here's what I have so far:-
$at = "#";
if (is_null($at[$email]))
{
return FALSE;
}
I hope someone can help me!
<?php
$email = "someone#example.com";
if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) {
echo "Valid email address.";
}
else {
echo "Invalid email address.";
}
?>
Or little bit more modern:
<?php
$email_address = "someone#example.com";
if (preg_match("/^[^#]*#[^#]*\.[^#]*$/", $email_address)) {
return "E-mail address";
}
?>
