PHP - Help With Improving Web Form Email Validation, Etc.

Hey guys.. I'm completely done with my contact form data validation except I cannot seem to get one part.  For my email field I need to make sure that it is a valid email address and not just words.  Also, I would like to make the phone number specific length.  Any ideas on how to go about this? thanks guys!

Hello,
I am working with a SMTP class to send an email. It's all working perfectly fine, but when the email is received (sent from the online form), and I open my email and click reply, there are two email addresses. The correct one (which I entered when I sent the email), and my ftp username for the site??

I've got three files that could effect this, but I was unable to locate any problems:
mailer.php ( smtp send mail class)
mail.php ( submission data: title, subject, etc. )
contact_form.php ( form for submission )

I am only including the file which I think is applicable (mail.php), but let me know if you would also like to see the mailer.php class.

Current output:

reply-to   ftpusername@domainname.com,
correct_from_email@fromemail.com

I am working on user validation through email and I am having some problems with it. I can get it to work but it gives me probloms some times.

This is the link that is sent to the users after they sign up
Code: [Select]
mydomain/confirm.php?id=".$id."&userkey=".$userkey

and this is what i have for the confirm page

Code: [Select]
<?php

//connection info

$userquery = mysql_query("SELECT * FROM user");
$active=mysql_result($userquery,  "active");
$userid=mysql_result($userquery,  "id");
$userkey=mysql_result($userquery, "userkey");


if ($active == 1) {

printf("This account has already been activated");
echo "<br />";
}

elseif($userkey != $posteduserkey){
printf("We are sorry but the data offered does not match data listed, plese contact system admin.");
}

else{
$query="UPDATE user SET active='1' WHERE id='$id'";

mysql_query($query) or die (mysql_error());  


echo "You have activated your account";

?>
<div align="center"><br /><a href="login.php" class="nav">Back to the log in page</a></div>

<?php
}

?>
This is the fun part. I checked that the id and userkey are correct in the link, and they are. I then replaced the & in the link with &amp; it works in gmail but not yahoo email address. I'm not sure where else to look.

Thanks in advance

Hello i have a syntax issue in the code below, can anyone shed some light?

Code: [Select]
<?php if(isset($_POST['submit']))
{
$drop = mysql_real_escape_string($_POST['drop_1']);
$tier_two = mysql_real_escape_string($_POST['Subtype']);
echo "You selected ";
echo $drop." & ".$tier_two;
$Name = mysql_real_escape_string($_POST["Name"]);
$Phone = mysql_real_escape_string($_POST["Phone"]);
$Email = mysql_real_escape_string($_POST["Email"]);
$Postcode = mysql_real_escape_string($_POST["Postcode"]);
$Website = mysql_real_escape_string($_POST["Website"]);
if($Name == '' || $Phone == '' || $Email == '' else if (!preg_match('/^[A-Za-z0-9\-.]+$/', $domain)||
$Postcode == '' || $Website == '')
{
die('<br> but you did not complete all of the required fields correctly, please try again');
}
}
the code works fine without the  " else if (!preg_match('/^[A-Za-z0-9\-.]+$/', $domain) " .
As well as checking for blank fields i'd like to check for the correct email format.

Many thanks.

Hi, I need simple function to validate email address format.

I have found follwoing function form google.


function isemail($email){
return (bool)ereg("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email);
}


It's working fine with php < 5.2. But when I'm using with PHP 5.3
is says Quote

Deprecated: Function ereg() is deprecated in C:\wamp\www\*******\includes\functions.php on line 28


Is any solution to this without error disable?

Thanks

Hello guys,

I just want to ask if someone can share me codes in php where i can validate the connection of the mail server.

I am going to trap this error:

Quote

Warning: mail() [function.mail]: Failed to connect to mailserver....


Instead of this message showing, I want it to be formal. It will be like this:

Quote

You cannot connect to you're mail server. Please contact the administrator.


And lastly I want to have a validation if an email is existing or not. I want a script which checks first the email if it is existing before sending the message. I hope someone will post their idea here. Thanks in Advance.


--CHILL 

Hey all, trying to figure out a logic flaw in this validation script. Basically if I use !preg_match or the preg_match examples (noted below), I do not get the correct results.   My interpretation of preg_match and my current understanding of the logic is noted below (please correct me if I'm wrong).  1. If I use alternate attempt !preg_match, the regex would be compared against the "string" in the $email variable. If the regex expression matches, error will be thrown and script would stop.  2. If I use alternate attempt !preg_match, the condition would be not true and move to else where the string contained within $email variable would be run through the vld function.  3. If I maintain the current script using preg_match, if the string matches the match, the condition would be true and therefore string of $email variable runs through VLD function else cleanup and throw error...   Are my statements above correct in this context? I think I'm pretty close to cracking it but seem to be missing something simple.   The current script is referenced below, forgive me if I've lost the plot. Long hours attempting to understand this language, from what I've seen so far its great.   Thanks in advance, A     //Alternate attempt   if (!preg_match("/^[^@]+@[^@.]+\.[^@]*\w\w/", $email)) {
                                    $error = "Please enter a valid email address"; } else {                                     $email = vld($_POST['email']);
                                  }   Current code that doens't work:   if (empty($_POST['email'])) {
    $error = "Email is required"; } else {
       if (strlen($_POST['email']) < 5) {
           $error = "Email is too short!"; } else {
              if (strlen($_POST['email']) > 30) {
                  $error = "Email is too long!"; } else {
                      if (preg_match("/[\(\)\<\>\,\;\:\\\"\[\]]/", $email)) {
                          $error = "The email address contains illegal characters"; } else {
                              if (preg_match("/^[^@]+@[^@.]+\.[^@]*\w\w/", $email)) {
                                  $email = vld($_POST['email']); } else {
                                      $error = "Please enter a valid email address";
                                  }
