I just posted something and had to go through the "Click the photos with street signs" test before my post was accepted. I was logged in. I don't remember ever doing this before here. Is this new? Is DW getting attacked with bots all of a sudden?

OK, here's a question for anyone willing to step up and answer or point to solution: I have some HTML forms for site visitors to request product information. Some of these forms send data to SalesForce. There has been an issue of spam coming through, so I have implemented CAPTCHA's via php (code created as an image), and have also gone through and setup additional checks on the form's fields. These checks are verifying that fields aren't blank, don't contain a url (a common item in the spam), and that email address is in proper form. In testing, there is …

Hello to all: I've been banging my head against the proverbial wall on this (for a few days), and finally thought I'd seek thoughts on it. I have an existing submission form that has been getting hit by bots, so I'm adding a CAPTCHA to it. The entire solution is in 4 files: - HTML form - PHP file generating 5 alphanumeric code to display as img in HTML - AJAX file to control/pass back values - PHP file for comparing CAPTCHA challenge and response What I'd like to do is have the system submit the form after it confirms …

I have a PHP script that generates a PNG captcha(set by Content-Type header).It can be embedded in an HTML page by just using `img`. I want to convert that image to base64 format for displaying.How do I go about doing that ? Using the normal method for encoding as given on Wikipedia's article([Click Here](http://en.wikipedia.org/wiki/Data_URI_scheme)) doesn't work.

Good Morning Ladies and Gents, I am having the following issue. I have implemented a captcha widget to my downloads page since there were a log of spam files that were coming through. After hours of working on this I have finally gotten the Captcha app to work and forward after successful entry to the actual download page. However, the lead info that was inputted in the form is not being forwarded as a lead at all. My guess is that the code is missing in the verify.php file. But I am not entirely too sure. Might have taken on …

So, I installed the recaptcha into my site... and I don't know why it doesn't verify... You can submit the form with out worrying about the code you have to type in so that recaptcha verifies the form. So... I have a form that shows recaptcha, but it doesn't verify... how do i fix this?

Hi, Iam trying to post a form with cookies using [Requests module](http://docs.python-requests.org/en/latest/). When I post the form and see the page with the results, there is an error in the page, saying that I didnt fill one field right. Iam absolute sure I fill that field right. When I post the data with web browser, its all right. I think it must be cookie problem, becose when I disable the cookies in the browser and post the right data, it shows the exact same error when I send it via Python. There is the code: # -*- coding: utf-8 -*- …

Hi, I have a wordpress site but really I'm looking for a plugin that will allow one word captcha. I have been searching for this but it doesn't appear to be the right name for it. What I want it to do is say "Please type the word frog" and if the user doesn't type the word frog, it doesn't submit the form. The word doesn't change, but the user has to be able to select the word. Does anyone know what the name of this kind of validation/captcha is? Also if you have seen a wordpress contact form plugin …

Hi there, I've been given the task of adding a Google recaptcha to a form on this website I'm working on. I'm not really familiar with the code that I've been given to edit, so I was wondering if anyone can help me. Basically, the "contact" page looks like this (below), but I need to add a recaptcha to the point in the code that says RECAPTCHA: [CODE] <?php require('sbsquared.class.php'); ?> <?php if(!empty($_GET['lang'])) { switch($_GET['lang']) { case 'fr': setlocale(LC_ALL, 'fr_FR.utf8'); $_SESSION['language'] = 'fr'; break; case 'us': setlocale(LC_ALL, 'en_EN.utf8'); $_SESSION['language'] = 'us'; break; case 'eu': setlocale(LC_ALL, 'en_EN.utf8'); $_SESSION['language'] = 'eu'; break; …

Hi, I made my own javascript method that I'd like to integrate into the JQuery validation plugin. I am new to JQuery and I'm not really sure how to integrate it though... Here is my javascript [B]working[/B] method: [CODE] function doAjax() { var captchaResponse = document.getElementById("registerCaptcha").value; $.ajax({ type: "POST", url: "register_captcha", data: "captchaResponse=" + captchaResponse, success: function(data) { alert(data); } }); } [/CODE] The only ways I know possible are: 1. Change the above code to use the remote method, which I've tried but isn't working for some reason: [CODE] $("#registerCaptcha").rules("add", { required: true, remote: { url: "register_captcha", type: "post", …

Hi all I am currently working on a project for tech (university). It's a login form that uses a CAPTCHA as validation and must monitor the IP address of the computer that has currently requested the form. The IP monitoring part is so that if a user has made x (let's say 5) wrong attempts, they must be blocked temporarily. The captcha works (few glitches here and there), the IP tracker works too. What I've thought to do is to store the IP addresses in a database along with a primary key to identify each address, then use that primary …

Hey all, To make it more user-friendly, I decided I want to add a JS form validation to my contact form. The essence of the JS should be that it calls for a check.php?input= with the entered captcha code appended. Then the PHP script would echo "valid" or "invalid". For the client-side scripting, this is what I have now: [CODE=js]function validate_captcha() { var url = 'check.php?input='; function getHTTPObject() { try { req = new XMLHttpRequest(); } catch (err1) { try { req = new ActiveXObject("Msxml12.XMLHTTP"); } catch (err2) { try { req = new ActiveXObject("Microsoft.XMLHTTP"); } catch (err3) { req …

Hello, I want to create a software in Java that submits same/similar data to multiple web forms (eg submit link data to link directories). What I want to do is, ask the user initially for the data that is to be submitted, and then go to the web form, open it, show only the captcha from that web form on screen, and the end user now has to fill in the captcha. After that, the form is submitted correctly with all data required by it. Should I manually create the entire data to be sent by that form in code, …

I have always used the API for Vb.net from Decaptcher.com and have always sent the Captcha by sending an actual url to them as you see in the code below. Or maybe it uploaded the image anyway to them (I use the Webbrowser Control) I'll use for example this: Code: [CODE] Dim dr As DecaptcherResult = DecaptAPI.GetCaptchaSolved(Me.WebBrowser1.Document.GetElementById("captcha_image").GetAttribute("src")) [/CODE] But with the current project that I am working on right now I am having to take a screen shot of the captcha image, then save it to my harddrive. I know that through your API Decaptcher allows us to upload the …

Just when you think you have heard every crackpot theory for fighting the spam menace, a new one comes along that makes you sit up and take notice. How does using pictures of kittens to foil spammers grab you? Bear with me, because the concept has some merit. Indeed, it was proposed by a researcher at the Microsoft 'Advanced Reading Technologies' group no less. Kevin Larson, speaking at the TypeCon 2007 conference in Seattle, has proposed a new twist on the Human Interactive Proofs (HIP) system best known through the CAPTCHA interface. HIP works by requiring a real human, as …
