PHP - How Can I Add This Email Validation To This Php Code

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

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";
                                  }
                         }
                  }
           }
    }
}

I am using this a modal window(jBox) - with a web Form in it, that requires the Form (just Name & Email) to be completed and Submitted in order to close the modal window - allowing access to the main page.

The Form uses this corresponding ../submit.php which this:

if (empty($_POST['name'])|| empty($_POST['email'])){
$response['success'] = false;
} else {
$response['success'] = true;
}

echo json_encode($response);

where, upon Form > submit, successfully shows 'error' if the Form fields are not populated, and 'success' when the Form fields are populated/submitted.

I'd like the Form to require a proper/valid email address and avoid spam and header injection
(maybe honeypot protection and implement a form of rate limiting (a single ip may not send more than x messages per day)).

Any assistance/guidance is appreciated

Hi guys,

Trying to ge this to work:


function  checkEmail($useremail) {
 if (!preg_match("/^( [a-zA-Z0-9] )+( [a-zA-Z0-9\._-] )*@( [a-zA-Z0-9_-] )+( [a-zA-Z0-9\._-] +)+$/" , $useremail)) {
  return false;
  $error = '<div id="blackText"><p>Sorry! Please check your email address and try again!<p><p><a href="forumsSignUp.php">Back</a></p></div>';
 }
 return true;

//PASSWORD AND OTHER VALIDATION STUFF, blah blah blah

}

But its just not. Everything works fine if I remove this though. Can anyone suggest an alternative to email address validation? 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 everyone. I hope you can help me getting through this problem, because I have no idea of what else to try. I'm a web designer and sometimes modify Javascript, but my main focus is HTML and CSS, meaning I have no idea how to code in Javascript, but most importantly, how to write something from scratch in PHP.

So I designed a form that works pretty well, and integrated a PHP and Javascript script to make it work. This is the form:

Code: [Select]
    <form name="form" id="form" method="post" action="contact.php">
    <p>Hello,</p>
    <p>My name is <input type="text" name="name">, from <input type="text" name="location">, and I'd like to get in touch with you for the following purpose:</p>
    <p><textarea name="message" rows="10" ></textarea></p>
    <p>By the way, my email address is <input type="text" name="email" id="email" placeholder="john@doe.com">, and I can prove I'm not a robot because I know the sky is <input type="text" name="code" placeholder="Red, green or blue?">.</p>
<p title="Send this message."><input type="submit"  id="submit" value="Take care."></p>
    </form>
And this is the script, in an external file called contact.php:

Code: [Select]
<?php
  $name = check_input($_REQUEST['name'], "Please enter your name.") ;
  $location = check_input($_REQUEST['location']) ;
  $message = check_input($_REQUEST['message'], "Please write a message.") ;
  $email = check_input($_REQUEST['email'], "Please enter a valid email address.") ;
  if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email)) {die("E-mail address not valid");}
  if (strtolower($_POST['code']) != 'blue') {die('You are definitely a robot.');}

  $mail_status = mail( "my@email.com", "Hey!", "Hello,\n\n$message\n\nRegards,\n\n$name\n$location", "From: $email $name" );
  
  function check_input($data, $problem='')
{
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    if ($problem && strlen($data) == 0)
    {
        show_error($problem);
    }
    return $data;
}

function show_error($myError)
{
?>
    <html>
    <body>

    <b>Please correct the following error:</b><br />
    <?php echo $myError; ?>

    </body>
    </html>
<?php
exit();
}

    if ($mail_status) { ?>
      <script language="javascript" type="text/javascript">
      alert('Thank you for the message. I will try to respond as soon as I can.');
      window.location = '/about';
    </script>
<?php
}
    else { ?>
    <script language="javascript" type="text/javascript">
      alert('There was an error. Please try again in a few minutes, or send the message directly to aalejandro@bitsland.com.');
      window.location = '/about';
    </script>
<?php
}
?>
So what it does is this: if everything's OK, it sends an email with "Hey!" as the subject, "[name]" as the sender, "Hello, [message]. Regards, [name], [location]" as the body, and a popup saying the message was delivered appears. If something fails, it outputs the error in a new address, so the user will have to go back to the form and correct the error.

What I actually want to happen is this: if everything's OK, a <p> which was hidden beneath the form appears saying the message was delivered, or, alternatively, make the submit button gray out and confirm the message was delivered. I found a script to make this happen, but with "Please wait...", so the user can't resubmit the form.

If there's an error, I'd like another <p> which was hidden to appear with the specific error, so there'd be many <p>'s hidden with different IDs. If possible, I'd also like to change the CSS style of the input field, specifically changing the border color to red, so it'd be a change in class for the particular field.

--

So in essence, I want the errors and the success messages to output in the same page as the form (without refresh), and a change of class in the input fields that have an error.

Thanks in advance, and please let me know if it'll be possible.

I have made a form that asks a user for email, first name, last name, and password. I am using Spry validation tools in Dreamweaver. When I used those only, I did not have a problem. The problem began once I tried to actually check to see if the email was already registered. I have tried changing so many things like what $_POST variable to look for at the beginning, to different db connection arrangements. I am stumped. The only other thing I can think of is that I have the order wrong somehow in the logic. Thanks for the help.

First, here is the form:

Code: [Select]
Enter Email<?php if($error_email_taken) echo ": $error_email_taken."; ?>
<form name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input name="email" type="text" id="email" value="<?php if($_POST["email"]) echo $_POST["email"]; ?>">
<input name="first" type="text" id="first" value="<?php if($_POST["first"]) echo $_POST["first"]; ?>">
<input name="last" type="text" id="last" value="<?php if($_POST["last"]) echo $_POST["last"]; ?>">
<input name="pass" type="password"  class="formText1" id="pass" value="<?php if($_POST["pass"]) echo $_POST["pass"]; ?>">
<input type="submit" name="Submit" value="Submit"></td>
</form>

And the email verification and insert, which is placed before the opening html tag.

Code: [Select]
<?php
if($_POST['Submit'])
{ //Check to see if email is registered.
$email = $_POST['email'];

$dbc=mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
$q_1 = "SELECT users_email FROM table WHERE users_email = $email";
$r_1 = mysqli_query($dbc, $q_1);
$rows_1 = mysqli_num_rows($r_1);
if ($rows_1 == 0) 
{ //If 0, email is not already registered.
$new_email = $_POST['email'];
} else {
$error_email_taken = "This email is already registered.";
}

//If everything is good, insert the information.
if(isset($new_email))
{
$first_name = $_POST['first'];
$last_name = $_POST['last'];
$password = $_POST['pass'];

//Insert User information.
$q_2 = "INSERT INTO table (users_email, users_first, users_last, users_pass) 
 VALUES ('$new_email', '$first_name', '$last_name', '$password')";
                $r_2 = mysqli_query($dbc, $q_2);

//Go to new page if form was submitted and information properly inserted.
header('Location: new_page.php');
}//End: if($new_email)
} //End: if $_POST['submit']
?>

I've simplified it as much as I could. I totally eliminated stuff like a password hash, etc. because I wanted to get it down to the most simple form, so once this gets working, I'll add that other stuff later. Thanks so much again.

I use this type of a code to send automatic emails from my website:

Code: [Select]
$headers = ;
$headers .= ;
$to = ;

Click here to go to Google.

", $headers);

I am having hard time figuring out how to do hyperlink on words (like here). If I do something like this:

Code: [Select]
<a href='http://www.google.com'>here</a>
it spits out that exact thing out.

Thanks you for your input

I have a form with PHP validation and also a mysqli query checking for duplicates in the database for mailing address and email address in mysql.     It works fine but the customers are adding spaces in the mailing address for example  111 mailing address A V  E, 1 1 1 ma iling address A V  E etc.  and my sql query doesn't see that as an address that's a duplicate.    Their alslo adding email address like my@emailaddress.com and m.y@emailaddress.com, m.y.2@emailaddress.com etc to bypass that comparision also.    Is there anyway to stop this from happening?        

The attached code works except the email portion. This code allows a user to upload a file(s) to a network share & has a few check mark boxs for John Doe & Jane Doe. If the box for John or Jane is checked it is suppose to send them an email once submit is pressed but the email does not get sent. Can someone help me out on this? Thanks

Help with PHP Email Code

I am currently designing a PHP website and i have been following some useful tutorials but one that i have followed i have come unstuck with and it wont work. If anyone could help me with the code below it would be a great help.

First of all we have the contact.html form

Code: [Select]
<html>
<head>

<style type="text/css">
body {
margin:50px 0px; padding:0px;

#submitbutton {

}
</style>

<script language="javascript">

function createRequestObject() {
var ro;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){
ro = new ActiveXObject("Microsoft.XMLHTTP");
}else{
ro = new XMLHttpRequest();
}
return ro;
}

var http = createRequestObject();

function sendemail() {
var msg = document.contactform.msg.value;
var name = document.contactform.name.value;
var email = document.contactform.email.value;
var subject = document.contactform.subject.value;
document.contactform.send.disabled=true;
document.contactform.send.value='Sending....';

http.open('get', 'contact.php?msg='+msg+'&name='+name+'&subject='+subject+'&email='+email+'&action=send');
http.onreadystatechange = handleResponse;
http.send(null);
}

function handleResponse() {
if(http.readyState == 4){
var response = http.responseText;
var update = new Array();

if(response.indexOf('|' != -1)) {
update = response.split('|');
document.getElementById(update[0]).innerHTML = update[1];

}
}
}
</script>
</head>
<body>
<div id="contactarea">
<form name="contactform" id="contactform">
<span id="inputlabel">Name:</span> &nbsp;&nbsp;<input type="text" name="name" id="inputbox">


<span id="inputlabel">Email:</span> &nbsp;&nbsp;&nbsp;<input type="text" name="email" id="inputbox">

<input type="button" value="Send Email" name="send" onclick="sendemail();" id="submitbutton">

Then we have the contact.php form

<?php

?>
From what i can gather the HTML form passes the information to the PHP form which then sends the information to your email address. I have changed the email address to the one that i want to use and have also tried using a different one incase it did not like the one i have chosen to use.

If anyone could help with this i would really appreciate it.

Thanks
