PHP - Custom Pages For Bots Detected From Dbs
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. Similar TutorialsHi im a little stuck... What im trying to do is when you request a page that is not there it goes to a custom error page. I have set the redirect via the .htaccess file. Basicly what im trying to do is only have one php file which displays the server response i.e. 404 error or 401 error and so on rather than having several error pages. So in the code Code: [Select] <h1>Oopppsss!!!! <!-- ERROR TO DISPLAY HERE i.e. 404 page not found --></h1> <p>There seems to be a problem... The page you are looking for does not exist or has moved. This is a permanent error. If you think this is a mistake please get in touch either by giving us a ring on 101010 or by filling out the web form on the <a href="contact-me.php">contact me</a> page...</p> Any thaught on how i can do this or is it not possible... Cheers I have no idea where to start or which board would be the proper place to put this but what I"m attempting to do is integrate this idea with my custom cms I'm making now is that once inside I can take down my site in case I (administrator) wanted to perform some maintenance on my site and have it instead display a custom 404 page. Any ideas on where to start. I tried using my best friend google but he gave me nothing. Maybe a few tutorials of this might help. Hi everyone, I am a beginner web designer and a novice php user. I am a regular forum user and understand that you should always do a search and try to find the answer yourself but I have done that and didn't get any results (or I didn't understand them!). So I ask for some assistance - either you can tell me the code or link me to the correct answer. I am working on a website that I have built a enquiry form for and it has a php script for it. I have managed to get the form running properly and got the reCaptcha working correctly (with a custom error page) but I do not understand how to add custom error pages for incomplete email addresses, empty email addresses, or for a blank form? I tried using the same tactic I used for the reCaptcha error page but it didn't work - probably because I was guessing and just tried it in a bunch of different places. The error msg that displays now is just a plain white page with the msg - Email address is invalid appearing at the top left. While this is suitably functional it doesn't really look like much so I want to build a custom page for each error that could happen. So the code is below - if anyone can point a beginner in the right direction I would be super happy. :mrgreen: if you need anymore code or other details just tell me and I will post them up. The url of the form page is http://www.sunsolutionshomeimprovement.com/onlinesales.html This is the code I think you will need - I got it from a demo php script that I have modified. As I said I don't have much clue what I'm doing so I just posted it exactly how it looks - if I over did it I apologize... :oops: 68.// Validate email field. 69. 70.if(isset($_REQUEST['email']) && !empty($_REQUEST['email'])) 71.{ 72. 73.if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST['email'])){$errors[] = "Email address may not contain a new line or 74.a colon";} 75. 76.$_REQUEST['email'] = trim($_REQUEST['email']); 77. 78.if(substr_count($_REQUEST['email'],"@") != 1 || stristr($_REQUEST['email']," ")){$errors[] = "Email address is invalid";}else{$exploded_email = explode("@",$_REQUEST['email']);if(empty($exploded_email[0]) || strlen($exploded_email[0]) > 64 || empty($exploded_email[1])){$errors[] = "Email address is invalid";}else{if(substr_count($exploded_email[1],".") == 0){$errors[] = "Email address is invalid";}else{$exploded_domain = explode(".",$exploded_email[1]);if(in_array("",$exploded_domain)){$errors[] = "Email address is invalid";}else{foreach($exploded_domain as $value){if(strlen($value) > 63 || !preg_match('/^[a-z0-9-]+$/i',$value)){$errors[] = "Email address is invalid"; break;}}}}}} 78. 79.) 80. 81.// Check referrer is from same site. 82. 83.if(!(isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){$errors[] = "You must enable referrer logging to use the form";} 84. 85.// Check for a blank form. 86. 87.function recursive_array_check_blank($element_value) 88.( 89. 90.global $set; 91. 92.if(!is_array($element_value)){if(!empty($element_value)){$set = 1;}} 93.else 94. 95. 96.foreach($element_value as $value){if($set){break;} recursive_array_check_blank($value);} 97. 98.) 99. 100.) 101. 102.recursive_array_check_blank($_REQUEST); 103. 104.if(!$set){$errors[] = "You cannot send a blank form";} 105. 106.unset($set); 107. 108.// Display any errors and exit if errors exist. 109. 110.if(count($errors)){foreach($errors as $value){print "$value<br>";} exit;} 111. 112.if(!defined("PHP_EOL")){define("PHP_EOL", strtoupper(substr(PHP_OS,0,3) == "WIN") ? "\r\n" : "\n");} 113. 114.// Build message. I don't think there is anymore that is relevant? I just want to reiterate that I know nearly nothing about this stuff so if you could keep your answers simple it would help a lot - cheers! hi i was wondering if anyone has any idea how to get this code to work for more then one browser? i can get it to work for one browser but have no luck on getting it to work for more then one browser thanks... code that don't work: Code: [Select] <?php include("browserDetection.php"); $user_browser = browser_detection('browser'); if ( $user_browser == 'mozilla' ) { echo("<link href='style.css' type='text/css' rel='stylesheet'></link>\n"); } else { echo("<link href='style1.css' type='text/css' rel='stylesheet'></link>\n"); } if ( browser_detection('msie') ) { echo("<link href='style.css' type='text/css' rel='stylesheet'></link>\n"); } else { echo("<link href='style1.css' type='text/css' rel='stylesheet'></link>\n"); } ?>code that works: Code: [Select] <?php include("browserDetection.php"); $user_browser = browser_detection('browser'); if ( $user_browser == 'Mozilla' ) { echo("<link href='style.css' type='text/css' rel='stylesheet'></link>\n"); } else { echo("<link href='style1.css' type='text/css' rel='stylesheet'></link>\n"); } ?> Hello, i am reading about bots and forms and using hidden input fields. I read that bots can be programmed to ignore hidden fields, so i made a text input named email and i use css to display none. i am having trouble detecting the email input. i've tried if (!empty($_POST['email'])) { echo 'test'; exit; } but i see 'test' on submission. if i add value="0" i still see test displayed. if i add text then i still see test displayed. why is this not working? also, a zero seems to bypass empty(). i'm not able to understand why this is failing. Hello, I'm using this plain and simple script below to count page views. Is there a way to identify a spider bot with php and then do something like.. if this visitor is a bot, don't count it. If not, count it? Here's my simple script: Code: [Select] $querySelect = mysql_query("SELECT * FROM video WHERE video.id = '$_GET[id]'"); $rowcount = mysql_fetch_assoc($querySelect); $count = $rowcount['counter']; if (empty($count)) { $counter = 1; $insert = mysql_query("INSERT INTO video (counter) VALUES ($counter) WHERE video.id = '$_GET[id]'"); } $add = $count+1; $insertNew = mysql_query("UPDATE video SET counter='$add' WHERE video.id = '$_GET[id]'"); thanks, Ryan Hi, I making a banner exchange script. Members will have to place a banner code on their sites to make banners appear. Some members might cheat by using bots to refresh the page to gain impressions and to waste other members impressions so i wanted to know if bots have ip addresses? because i want to only give member impressions if their visitors have ip. What are the other things i can do to check if members are cheating?. Thanks
$ip=$_SERVER['REMOTE_ADDR']; Is there any way to prevent bots from getting past a math captcha? I have 2 numbers generated randomly (from 1 to 20) and they are displayed in an image with the following lines: one going from the upper left corner to the lower right corner one going from the upper right to the lower left a vertical line in the middle of the image and a horizontal line in the middle.... Now I keep getting bots posting on my comments page every few weeks...is there a more effective method I should try in order to stop this? I have the answer stored in a session variable. I was going to try random numbers from (1 to 100). I also have a php counter on my webpage that has a file that the number of hits is written to and it seems everytime the bots post get past my captcha, the number of hits in the file is overridden. (It will go from 538 views down to 10 views).... Any ideas??? 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...
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 $country" ?>"> <?php display_tooltip("Please enter your starting point in the form address, city, state zip country or simply enter your city", "mapdir");?> <input type="text" name="saddr" value="your starting point" onfocus=this.select()> <input class="clickableL" type="submit" value="Map and Directions"> </form> I'm sure it's not much, but I'm not understanding something with custom error handlers: I've created a custom error handler, which I initially set when my page loads : set_error_handler(array ( new ErrorHandler(), 'handleError' ));
It seems to catch all internal PHP errors, such as if I: var_dump($non_existing_var); right after the set_error_handler.... Now, I have an object that throws an exception after: set_error_handler(array ( new ErrorHandler(), 'handleError' )); $locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception ... I thought that with an error handler set, I could 'skip' the try/catch for it, but doing so, PHP spits out in its internal log: PHP Fatal error: Uncaught CorbeauPerdu\i18n\LocaleException: ....
My error handler doesn't catch it at all before, thus my page breaks!! If I want it to go through the error handler, I have to init my Locale with a try/catch and use trigger_error() like so:
set_error_handler(array ( new ErrorHandler(), 'handleError' ));
try {
$locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception
}
catch(Exception $e) {
trigger_error($e->getMessage(), E_USER_ERROR);
}
...
Is this normal ? I thought one of the goals of the error_handler was to catch anything that wasn't dealt with? Thanks for your answers! Hello everyone, I'm just starting out with PHP as I need to create an online bookstore for a school project. I'm working by a magazine which should teach you exactly how to do this using PHP, but I've had a bunch of problems with the code they use and I don't really know what's going on. Anyway, this looks really simple and basically what it does is allows you to post a comment on a book, then returns you to the book's page. Problem is, I'm getting the Header may not contain more than a single header, new line detected. error and I can't figure out why. I've tried researching into the matter but all the cases I found had to do with returning to an url, which is not my case. Anyway, here's the snippet of code: The form: Code: [Select] <div style="width:400px; border:1px solid #ffffff; background-color:#F9F1E7; padding:5px"> <b>Adauga opinia ta:</b> <hr size="1"> <form action="adauga_comentariu.php" method="POST"> Nume: <input type="text" name="nume_utilizator"><br><br> Email: <input type="text" name="adresa_email"><br><br> Comentariu: <br> <textarea name="comentariu" cols="45"></textarea><br><br> <input type="hidden" name="id_carte" value="<?=id_carte?>"> <center><input type="submit" value="Adauga"</center> </form> </div> The script adaugare_comentariu.php: Code: [Select] <?php ob_start(); include("conectare.php"); $numeFaraTags=strip_tags($_POST['nume_utilizator']); $emailFaraTags=strip_tags($_POST['adresa_email']); $comentariuFaraTags=strip_tags($_POST['comentariu']); $sql="insert into comentarii (id_carte, nume_utilizator, adresa_email, comentariu) values(".$_POST['id_carte'].", '".$numeFaraTags."','".$emailFaraTags."','".$comentariuFaraTags."')"; mysql_query($sql); $inapoi="carte.php?id_carte=".$_POST['id_carte']; header("location:urldecode($inapoi)"); ob_end_flush(); ?> conectare.php connects to the mysql database. $inapoi is the variable which returns the user to carte.php (the book he posted a comment on), where id_carte is the book's unique id. I'm getting Header may not contain more than a single header, new line detected on line ten, which is the header line. Can anyone help me? I've been stumped on this for a few days now and I've just let it pass and started working on other bits, but it's bugging me too much and I'd like to fix it. I am in the process of learning MySQL and PHP. I have a real-world application that I would like to develop for someone using MySQL and PHP, provided I can end up with the necessary user interface for the application. The user will be launching a web browser to start the application. The application will be developed for two purposes: to record employee information (name, contact info, category of worker such as: cook, dishwasher, server, host) to record the hours worked by each worker for each day and then generate a report that can be sent to the accountant by email or fax Since the interaction will take place in a web browser, what are the possibilities as far as having customization for the text fields (controllable size of text field, larger than the form element), having start and end times with the colon symbol inserted automatically, to name a few. When a text field is inserted via HTML, the rectangle is rather small. Can the default sizes of form elements be enlarged? I'm gonna be perfectly honest, I have no idea what's wrong with this code, I'm not even entirely sure what it all means, I just need to make it work. -.- I get this error: Parse error: syntax error, unexpected '}' in Z:\www\cms\includes\functions.php on line 25 From this code: Code: [Select] <html> <body> <?php include('includes/dbvars.php'); function displayVideos($dbc){ mysqli_connect('DB_HOST', 'DB_USER', 'DB_PW', 'DB_NAME'); //Query $query = "SELECT * FROM videos"; //Execute $result = mysqli_query($dbc, $query) or die ("Error querying database."); While ($row = mysqli_fetch_assoc($result)) { echo '<h2>' . $row['Title'] . '</h2>'; echo '<b>Director</b>:' . $row['Director'] . '<br />'; echo '<b>Description</b>:<br />' . $row['Description']; echo '<hr>'; } mysqli_close($dbc) } ?> </body> </html> Any help very much appreciated Is there a way to use PHP to edit html without having to store it in my DB? For example I would like someone to be able to edit a paragraph on the page, its wrapped in a <div class="editable"> now is there a way to have PHP detect that div and have an textarea to edit it directly without having to store anything in a DB? I hope that makes sense if it doesn't let me know! Thanks Hi guys, i have a ipn paypal setup where users can buy items from my custom made shop, however in original ipn code, the logged in users should have the same email with paypal to call on ipn which user has bought what, so I have decided to pass a custome variable as <input type="hidden" name="custom" value="<?php echo "$username";"> the hard part is in my ipn how im i going to recieve the username variable? what should i put in my ipn. In ipn code I have example code: $item_name = $_POST['item_name']; $item_number = $_POST['item_number']; $payment_status = $_POST['payment_status']; $payment_amount = $_POST['mc_gross']; $payment_currency = $_POST['mc_currency']; $txn_id = $_POST['txn_id']; $receiver_email = $_POST['receiver_email']; $payer_email = $_POST['payer_email']; but now, can u help me to recieve the username so i can match my mysql query which user has bought what? thanks in advance Hi all I wonder if people can help me out here. It's a "bespoke" vs "framework" question, so not sure its belongs in here, but I didn't want to post it in the ZEND group, as it may have many more "pro ZEND fans" who read it, and I wanted a general thought. This is all based on the fact that I have a big project coming up and I want to know if I should be sticking with a custom job, or if something like ZEND is the way to go. Basically I have been developing PHP for about 2 years now and I have always thought a custom site written from scratch was the best way to go, not only does it allow you to have the minimal code needed to run the site, therefore reducing load, space and bandwidth, but it also allows you to know exactly how the system works, I guess the downside is that you have to spend more time doing the coding. But I have a few friends who use frameworks, ZEND has been coming up more and more, it's not really my ideal system to use as I prefer coding from scratch (not sure why), but they swear by it, and always tell me its great, its winning awards and none of them code from scratch, one of them even quoted that it "will become the standard for development" - is this true? Apart from being massively bulky and containing tons of files with scripts and functions that you might never ever use, what do people see as a downside to ZEND, If any? Is it best to code from scratch, and if so, why? Or does using something like ZEND much better? I guess if you always use ZEND, then you never really enhance your skill as a coder and never really learn anything new, plus I always think it's kind of cheeky using a pre-built system. Is there a good argument that would say using ZEND is not really a good idea? Or is the general feeling toward ZEND being a good thing? Surely if people know ZEND, they know how to play the security of the site to there advantage and therefore can break the security of other ZEND systems, or at least cause some hacks to a site. Any thoughts would be great Thanks everyone Hi. I was just wondering if it is possible to write custom mysql errors. I have hunted around for some but cant find any. Currently I write my errors like... or die (mysql_error()); How ever I see this as a problem! As Im not the best coder there are bound to be errors in my code. I dont want somebody who knows what they are doing to cause an error and then doing it (mysql_error()) will point them in the right direction to what I have missed. I would rather have my own error saying what line the issue is with. I have tried..... or die (mysql_error(My personal error here)) However this does not work. Please help. Thank you Hello. I am currently working on a new site (http://sa.cx) that is basically a free domain like this: (example.sa.cx). My main goal is to allow users to set the the full MX, CNAME, A and SOA records. Any ideas on how I could go about this using php? My initial thought would be via cURL. |
