PHP - Bots Getting Past Math Captcha

Hello every1,   I'm trying to create a magazine wesite and I dont want anybody to access my images folder which is located in the root directory.   I want some thing like this...   I want to call the images in my website using <img> tag but I dont want any1 to access the directory directly.   It should also protect from software bots also like (HTTrack or website Copier)   It should show "Access forbidden".   Any help will be greatly appreciated.   Thank you...    

if I have a list of 5,000 bots and their server header into in my DBs, can someone point me to a web resource that can give me any insight into how to show a custom page if a bot is detected at the render request? I can look up PHP functions myself and possibly use header(), but didn’t know if anything special was involved that I don’t already know about. so, say for instance, as a joke I want to do this:

<?php
$ip = gethostbyaddr($_SERVER['REMOTE_ADDR']);
   if (substr($ip, 0, 3) = '10.') {
      echo 'sorry, but we do not display content to USA government's automated server sniffing bots.';
}
?>

how much of a pain in the rear would it be to display custom pages for ‘‘x’’ number of automated hits? I realize that this is pointless because most are just from researching orgs the world over, but it IS a relevant question to ask. thanks.

Hello

We have a series of sites that use Google API to serve locations stored in local DB, that show google maps from within given PHP pages within our sites (these pages also have other db driven content we wish to keep....

Each 'member' in our sites,  they each have a google map shown on each page present for their 'location' menu tab...

These calls to the google map API,  often goes over our daily allotment of freebie map presentations from the google API

It is SE and other Bots that run these view numbers off the charts and prevent the google maps from loading the actual maps - we get a google map err message - advising that maximum views have been reached... (we see this in our server error logs)

Thoughts on how i can serve this map code to only legit http requests (human eyes)  or at least reduce the burden of bot crawl requests to the google API?

here is the code we use to call the maps

 - We need to encapsulate Google Map Display in a snippet that will block it from getting hit by bots....

Huge Thanks!

Code: [Select]
<form target="_blank" method="GET" action="http://maps.google.com/maps">
<input type="hidden" name="daddr" value="<? echo "$address, $city, $state $zip $country" ?>">
<?php display_tooltip("Please enter your starting point in the form address, city, state zip country or simply enter your city", "mapdir");?>
<input type="text" name="saddr" value="your starting point" onfocus=this.select()>
<input class="clickableL" type="submit" value="Map and Directions">
</form>

Okay, I have a healing spell that allows people to regain stats when it's cast. But, how do I limit it so that they can't go over their maxhp?

Here's what I have so far:


$db->execute("UPDATE `users` SET `hp`=?, `mp`=?, `energy`=? WHERE `id`=?", array($player->hp + $healspell, $player->mp - $spell['mp'], $player->energy - $spell['energy'], $player->id));


What do I need to do in this to tell it to limit it to the maxhp but never going over it? $healspell is a random number, so it is quite possible to go over the maxhp at the moment.

Thank you!

Hi, I am having a problem with my Website mail.  Basically the mail was working fine yesterday but last night I  edited the PHP script slightly because for some reason the page that it was directed to had gone missing and was turning up an 404 error, which was just a newsuince as the email was still sent. So I just edited it so that it echo'ed a message saying thanks. but is seems today the mail is not getting to its destination. The PHP returns no errors and returns the success message fine but after saying its been sent it never appears.
I have tried different email addresses on different servers and that was no use and I have also changed the code back to how it was yesterday. and it still doesn't work.
I have also put the page up on one of my other sites which I know everything is set up properly and it works fine, making me think that it is a mail setup issue. but as I did not set up the mail at all and quite frankly don't really understand it, I don't know how it is meant to be set up as I just use google apps for sites that I set up.

So yeah I am trying to work out what could have gone wrong since yesterday but I don't really understand it,
below is the code as it as now and as it was yesterday:
Code: [Select]
<?php

$EmailFrom = "johnshale@hotmail.co.uk";
$EmailTo = "matthale.live@gmail.com";
$Subject = "Website enquiry";
$Name = Trim(stripslashes($_POST['Name'])); 
$Tel = Trim(stripslashes($_POST['Tel'])); 
$Email = Trim(stripslashes($_POST['Email'])); 
$Message = Trim(stripslashes($_POST['Message'])); 

// validation
$validationOK=true;
if (!$validationOK) {
  print "<meta http-equiv=\"refresh\" content=\"0;URL=error.htm\">";
  exit;
}

// prepare email body text
$Body = "";
$Body .= "Name: ";
$Body .= $Name;
$Body .= "\n";
$Body .= "Tel: ";
$Body .= $Tel;
$Body .= "\n";
$Body .= "Email: ";
$Body .= $Email;
$Body .= "\n";
$Body .= "Message: ";
$Body .= $Message;
$Body .= "\n";

// send email 
$success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>");

// redirect to success page 
if ($success){
  print "<meta http-equiv=\"refresh\" content=\"0;URL=contactthanks.php\">";
}
else{
  print "<meta http-equiv=\"refresh\" content=\"0;URL=error.htm\">";
}
?>
and the page is at www.sullyco.co.uk/contactengine.php as you can see the page is redirecting to a page that does not exist(contactthanks.php) indicating that the message was sent successfully. it is also the part I edited as a quick fix last night I just got it to echo a success message.


Thanks for any help on this, I have been trying to work it out all morning,
Matt

Hi,

I am having issues getting a simple contact form getting past the junk filter and into the inbox. Is there something wrong with my code?

I have tried to set the email to 'not junk' in the 2 different email providers, but not change.


Here is my code:

Code: [Select]
<?php
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'From: Contact Form'; 
    $to = 'my_email@gmail.com'; 
    $subject = 'Hello';
    $human = $_POST['human'];

    $body = "From: $name\n E-Mail: $email\n Message:\n $message";

  $headers .= "Content-type: text/plain; charset=utf-8\n";
  $headers .= "From: website user<someone_from@mysite.com> \n";


if ($_POST['submit']) {
    if ($name != '' && $email != '') {
        if ($human == '10') {  
            if (mail ($to, $subject, $body, $from)) { 
        echo '<p>Your message has been sent!</p>';
    } else { 
        echo '<p>Something went wrong, go back and try again!</p>'; 
    } 
} else if ($_POST['submit'] && $human != '4') {
    echo '<p>You answered the anti-spam question incorrectly!</p>';
}
    } else {
        echo '<p>You need to fill in all required fields!!</p>';
    }

Any help is greatly appreciated.

My query is a fixtures list for my local sports team- There seems little point including fixtures from the past as they are in a results query anyway.
I'm ordering by date (see below) but how can I remove the ones already past?

$query = "SELECT * FROM fix10 ORDER BY Date";

TIA Nick

First the problem is not so much php relate, as i actually doing it in C# however regular expression are same on all of them and i dont know any c# forums as good and active as phpfreaks so I've decided to post it here.


My text is:
Code: [Select]
<div class="15ma">text-special character - numbers </div><div class="15ma">text-special character - numbers </div><div class="15ma">text-special character - numbers </div><div class="15ma">text-special character - numbers </div><div class="15ma">text-special character - numbers </div>
No spaces between the dives or new lines.

I thought of using this pattern:
Code: [Select]
<div class="15ma">(.+)<\/div>

However kept looking at it and it just grabs the first <div class="15ma"> and the last </div> since i used (.+) it consider all the other as part of the inside text..

Any help would be highly appreciated.

Thanks in advanced.

The following code is what I am trying to use for doing a form captcha style verification and all it is throwing back when I load the page is an image of the website address. Does anyone here know where I am going wrong? I have been at this all day and gotten nowhere. Thanks in advance

imagestring ($img, 5, 5, 8, $rndval, $fontcolor);

Hi, I am making a CAPTCHA image.  I am pretty sure the code I have is correct, but I am getting these error messages when I run the script.  I use GoDaddy for hosting.  The font that I reference in the script is in the root directory with the script.  Any ideas? 

Thanks,
Craig

I want to build a captcha from scratch, as I'm all about doing things myself, and I've proposed a nice idea on how I can achieve that, but I'm sort of lost...

What I want to do is write a script that will generate a random string of both letters and numbers, with the ability to set a limit on how many characters are generated.  Then, I want to store that string within a variable called "random_string".

Once the user types in that code, their input would get captured in a separate php file and stored within a variable like so:
$captcha_code = $_POST['catpcha_code'];

Then, I would write a code to see if the user's input matches the random character string from the html:
Code: [Select]
<?php
if ($random_string == $captcha_code) {
mail($to, $subject, $body);
} else {
echo ("The code you entered did not match the captcha. Please go back and try again.");
}
?>
Is this possible? I haven't yet tried it myself, because I don't know how to generate random strings of characters, but I was just wondering if perhaps I'm on the right track? Any suggestions or advice is appreciated =)
