How can i validate the email, so it's not fake...

[Breana]

Ok, recently i found over 35 fake emails signed up on my site using .con .fk .up .ip .nk .dk and no @ sign so i need to make it so it requires a real email.

mymail@yahoo.co m or others but no mymail.host253. dk!
This is how i have it now what do i need to add?

[PHP]$error = false;
$errormessage = "";

if (strlen($emaila ddress) < 1) {
$error = true;
$msg .= "Sorry. You did not enter an email address.";
} else {

$sql = "select * from subscribers where emailaddress = '$emailaddress' ";[/PHP]

And 3 signed up to be members no "ip or email" submited but in the about me feild was links to there site porn ewwweeee.
I HATE THEM ALREADY!

So i need to get help making a security code on the register page so if it is not entered no signup1

I would like to make it with words not numbers, random.
Please help i cant have this going on i just got listed in the search now this :(

You can use regular expressions for that.

Please see http://www.regular-expressions.info/email.html and http://www.php.net/preg_match

:)

--[Edit]--
Sorry, I didn't read all the way through. If you don't like the required email format trick above, then it looks like you want a form of "CAPTCHA". Here's a nice tutorial for that :)

Hi.

You need to have the GD extension in order for the Captcha code to work.

If that is all in order, could you show us the code that you use to display the image?

[Breana]

Can i install the gd on my free host? i havent got the paid host yet...

[PHP]<tr>
<td colspan="2"><fo nt color="#003366" size="1" face="Arial"><b r />
<img src="images/Dotted_Border.p ng" width="500" height="10" /><br />
Security Code.</font></td>
</tr>
<tr>
<td><img src="../CaptchaSecurity Images.php" /></td>
<td><input id="security_co de" name="security_ code" type="text" /></td>
</tr>[/PHP]

Or can it be done with words or numbers not an image?
I just want simple not high tech..

[Breana]

Is it possible to have it load in a textbox not an image, i have seen several sites doing it that way or with plane text.

I just need it to be simple like that i have been searching all morning but no luck...

UPDATE, well i founf a nice chapa and it works but i am having trouble intragrating it into my error string!

I want it not to exit and be in the same error string as the rest, if no echo error and so on..
Be cause as it sits now it echos error bad code but if the rest is ok it still creats the users lol.

Here is the new code.
On the form.
[PHP]<tr>
<td colspan="2"><?p hp
// vim:set ts=4 sw=4 ai:
include('Captch aSecurityImages .php');

$guess = $_REQUEST['guess'];

$c = new Craptcha( $_SERVER['REMOTE_ADDR'] );
?>
<font color="#003366" size="1" face="Arial">Wh at is the total of</font> <font color="#FF0000" size="-2"><?=$c->toString()?> ?</font><br />
<input type="text" name="guess">
<font color="#003366" size="1" face="Arial">(a nswer in written English)</font></td>
</tr>[/PHP]

And in the saveuser.php is this.
The chapa code, is above my other error code:
[PHP]<?php
// vim:set ts=4 sw=4 ai:
include('Captch aSecurityImages .php');

$guess = $_REQUEST['guess'];

$c = new Craptcha( $_SERVER['REMOTE_ADDR'] );

if ($guess)
{
if ($c->answerMatches( $guess))
{
$c->clear();
}
else
{
echo "Incorrect Security Code!\n";
exit;
}
}
?>[/PHP]

Other code i use:
[PHP]<?php

$error = false;
$errormessage = "";

if (strlen($loginn ame) < 1) {
$error = true;
$errormessage .= "<font color=\"#FF0000 \">Sorry,</font> You did not enter a Login name.</b><br>\n";

$error = true;
$errormessage .= "<font color=\"#FF0000 \">Sorry,</font> You did not enter a password.</b><br>\n";
}

$error = true;
$errormessage .= "<font color=\"#FF0000 \">Sorry,</font> You did not enter a confirmation password.</b><br>\n";
}

if (strlen($email) < 1) {
$error = true;
$errormessage .= "<font color=\"#FF0000 \">Sorry,</font> You did not enter an email address.</b><br>\n";
