i'm a beginner programmer who have to provide huge project very soon ..
i have a dynamic website
The problem is that there is an html form on it as the page which allowing the user to making his post "create.html" : write a text in the Textarea and upload an images or video too
well, i'm sure this request sounds very stupid but i'm really so confused ..
i have my own database, and what i want to do is when the user submit his form, all of that inputs should be published on the Index page "index.html" also the " comment, like ..etc." buttons should appears bellow the post
here is a pic for the index page and how the post should be:
index.html
i need an explanation to do that more than a real codes i think, and sorry for my bad grammar i tried my best
hope you could help me :( i'm ready to pay $$
So, I feel like I'm really close to a breakthrough here but moving forward is going to require some help.
I have a survey, we will call it "test".
To get to the survey, you click a link that has your email included as a jscript passthrough (e.g., https://osu.az1.qualtrics.com/SE/?SID=SV_abcdefg&ID=john.doe#emailtest.com)
I want to autoauthenticate john doe against a panel.
What I mean by that is that I want to use an authenticator that doesn't require a person to enter any data, but uses the data in the URL as an authenticator. You would think this can't be done, but I've also learned that you can run javascript in the description field by looking at:
https://sites.google.com/a/cognitivescience.co/research-using-qualtrics/home/functions-capacities-in-qualtrics/using-qualtrics-as-a-personalized-web-service-with-the-authenticator
However, all that does is change the label for the field and doesn't actually authenticate. It does, however, process the next button. This suggests that if I can fill in the authenticator with the embedded data passed through the URL using JavaScript, I should be able to autoauthenicate.
Any ideas?
Strange example; I don't see how it ever would have worked. Anyway, if you add the embedded data field ID to your survey flow before the Authenticator, then you could put a script like the following in label field:
<script>Qualtrics.SurveyEngine.addOnload(function(){$$('.InputText').first().value="${e://Field/ID}";$('NextButton').click();});</script>
I need help.
We need to find a questionnaire in which the answer to the question (for example, telephone number) may not be the same for two users.
For Example:
Enter a phone number:
First the user enters a phone number: 123456789
And completes the survey.
The second user starts to question and answers the same phone number 123456789.
He receives an error message or a request to enter a different answer.
Or is there any easy implementation of this problem using php or javascript.
Maybe it is possible to implement with surveymonkey api.
I would be glad of any help or advice.
Google forms writes to a spreadsheet database, allows regular expression fields and attached scripts. Set the field to mach your required format, then validate the response with a script.
Your requirement is persistent storage. You will either require a database, such as MySQL, and use PHP to access it, or a third party application such as SurveyMonkey. However, I can't tell you the limitations of SurveyMonkey, you will have to check their documentation.
I realize that this late and this thread is limited but for others looking for same answer. Here is how I did exactly the same thing for one of my coworkers using Examinare Framework and Examinare Survey Tool.
First, create a html form that sends the phone number to a form.
Inside that PHP file call Examinare PHP Wrapper and check if a recipient has this phone number on their recipient profile.
https://developer.examinare.com/apidocs/listrecipientsbygroup/
A tip: And loop through it the results.
If the recipient not exist, create the recipient. Make sure you add a fake or real email to prevent getting an error.
https://developer.examinare.com/apidocs/addrecipient/
Mark the recipient as a active in the survey.
https://developer.examinare.com/apidocs/markrecipientstosurvey/
Redirect to the survey.
If you want the recipient to return to a certain path then add redirect_url variable to the url with a valid url.
Hope it helps you and future seakers.
I'm trying to figure out a good way to prevent bots from submitting my form, while keeping the process simple. I've read several great ideas, but I thought about adding a confirm option when the form is submitted. The user clicks submit and a Javascript confirm prompt pops up which requires user interaction.
Would this prevent bots or could a bot figure this out too easy? Below is the code and JSFIddle to demonstrate my idea:
JSFIDDLE
$('button').click(function () {
if(Confirm()) {
alert('Form submitted');
/* perform a $.post() to php */
}
else {
alert('Form not submitted');
}
});
function Confirm() {
var _question = confirm('Are you sure about this?');
var _response = (_question) ? true : false;
return _response;
}
This is one problem that a lot of people have encountered. As user166390 points out in the comments, the bot can just submit information directly to the server, bypassing the javascript (see simple utilities like cURL and Postman). Many bots are capable of consuming and interacting with the javascript now. Hari krishnan points out the use of captcha, the most prevalent and successful of which (to my knowledge) is reCaptcha. But captchas have their problems and are discouraged by the World-Wide Web compendium, mostly for reasons of ineffectiveness and inaccessibility.
And lest we forget, an attacker can always deploy human intelligence to defeat a captcha. There are stories of attackers paying for people to crack captchas for spamming purposes without the workers realizing they're participating in illegal activities. Amazon offers a service called Mechanical Turk that tackles things like this. Amazon would strenuously object if you were to use their service for malicious purposes, and it has the downside of costing money and creating a paper trail. However, there are more erhm providers out there who would harbor no such objections.
So what can you do?
My favorite mechanism is a hidden checkbox. Make it have a label like 'Do you agree to the terms and conditions of using our services?' perhaps even with a link to some serious looking terms. But you default it to unchecked and hide it through css: position it off page, put it in a container with a zero height or zero width, position a div over top of it with a higher z-index. Roll your own mechanism here and be creative.
The secret is that no human will see the checkbox, but most bots fill forms by inspecting the page and manipulating it directly, not through actual vision. Therefore, any form that comes in with that checkbox value set allows you to know it wasn't filled by a human. This technique is called a bot trap. The rule of thumb for the type of auto-form filling bots is that if a human has to intercede to overcome an individual site, then they've lost all the money (in the form of their time) they would have made by spreading their spam advertisements.
(The previous rule of thumb assumes you're protecting a forum or comment form. If actual money or personal information is on the line, then you need more security than just one heuristic. This is still security through obscurity, it just turns out that obscurity is enough to protect you from casual, scripted attacks. Don't deceive yourself into thinking this secures your website against all attacks.)
The other half of the secret is keeping it. Do not alter the response in any way if the box is checked. Show the same confirmation, thank you, or whatever message or page afterwards. That will prevent the bot from knowing it has been rejected.
I am also a fan of the timing method. You have to implement it entirely on the server side. Track the time the page was served in a persistent way (essentially the session) and compare it against the time the form submission comes in. This prevents forgery or even letting the bot know it's being timed - if you make the served time a part of the form or javascript, then you've let them know you're on to them, inviting a more sophisticated approach.
Again though, just silently discard the request while serving the same thank you page (or introduce a delay in responding to the spam form, if you want to be vindictive - this may not keep them from overwhelming your server and it may even let them overwhelm you faster, by keeping more connections open longer. At that point, you need a hardware solution, a firewall on a load balancer setup).
There are a lot of resources out there about delaying server responses to slow down attackers, frequently in the form of brute-force password attempts. This IT Security question looks like a good starting point.
Update regarding Captcha's
I had been thinking about updating this question for a while regarding the topic of computer vision and form submission. An article surfaced recently that pointed me to this blog post by Steve Hickson, a computer vision enthusiast. Snapchat (apparently some social media platform? I've never used it, feeling older every day...) launched a new captcha-like system where you have to identify pictures (cartoons, really) which contain a ghost. Steve proved that this doesn't verify squat about the submitter, because in typical fashion, computers are better and faster at identifying this simple type of image.
It's not hard to imagine extending a similar approach to other Captcha types. I did a search and found these links interesting as well:
Is reCaptcha broken?
Practical, non-image based Captchas
If we know CAPTCHA can be beat, why are we still using them?
Is there a true alternative to using CAPTCHA images?
How a trio of Hackers brought Google's reCaptcha to its knees - extra interesting because it is about the audio Captchas.
Oh, and we'd hardly be complete without an obligatory XKCD comic.
Today I successfully stopped a continuous spamming of my form. This method might not always work of course, but it was simple and worked well for this particular case.
I did the following:
I set the action property of the form to mustusejavascript.asp which just shows a message that the submission did not work and that the visitor must have javascript enabled.
I set the form's onsubmit property to a javascript function that sets the action property of the form to the real receiving page, like receivemessage.asp
The bot in question apparently does not handle javascript so I no longer see any spam from it. And for a human (who has javascript turned on) it works without any inconvenience or extra interaction at all. If the visitor has javascript turned off, he will get a clear message about that if he makes a submission.
Your code would not prevent bot submission but its not because of how your code is. The typical bot out there will more likely do an external/automated POST request to the URL (action attribute). The typical bots aren't rendering HTML, CSS, or JavaScript. They are reading the HTML and acting upon them, so any client logic will not be executed. For example, CURLing a URL will get the markup without loading or evaluating any JavaScript. One could create a simple script that looks for <form> and then does a CURL POST to that URL with the matching keys.
With that in mind, a server-side solution to prevent bot submission is necessary. Captcha + CSRF should be suffice. (http://en.wikipedia.org/wiki/Cross-site_request_forgery)
No Realy are you still thinking that Captcha or ReCap are Safe ?
Bots nowDays are smart and can easly recognise Letters on images Using OCR Tools (Search for it to understand)
I say the best way to protect your self from auto Form submitting is adding a hidden hash generated (and stored on the Session on your server of the current Client) every time you display the form for submitting !
That's all when the Bot or any Zombie submit the form you check if it the given hash equals the session stored Hash ;)
for more info Read about CSRF !
You could simply add captcha to your form. Since captchas will be different and also in images, bots cannot decode that. This is one of the most widely used security for all wesites...
you can not achieve your goal with javascript. because a client can parse your javascript and bypass your methods. You have to do validation on server side via captchas. the main idea is that you store a secret on the server side and validate the form submitted from the client with the secret on the server side.
You could measure the registration time offered no need to fill eternity to text boxes!
I ran across a form input validation that prevented programmatic input from registering.
My initial tactic was to grab the element and set it to the Option I wanted. I triggered focus on the input fields and simulated clicks to each element to get the drop downs to show up and then set the value firing the events for changing values. but when I tried to click save the inputs where not registered as having changed.
;failed automation attempt because window doesnt register changes.
;$iUse = _IEGetObjById($nIE,"InternalUseOnly_id")
;_IEAction($iUse,"focus")
;_IEAction($iUse,"click")
;_IEFormElementOptionSelect($iUse,1,1,"byIndex")
;$iEdit = _IEGetObjById($nIE,"canEdit_id")
;_IEAction($iEdit,"focus")
;_IEAction($iEdit,"click")
;_IEFormElementOptionSelect($iEdit,1,1,"byIndex")
;$iTalent = _IEGetObjById($nIE,"TalentReleaseFile_id")
;_IEAction($iTalent,"focus")
;_IEAction($iTalent,"click")
;_IEFormElementOptionSelect($iTalent,2,1,"byIndex")
;Sleep(1000)
;_IEAction(_IETagNameGetCollection($nIE,"button",1),"click")
This caused me to to rethink how input could be entered by directly manipulating the mouse's actions to simulate more selection with mouse type behavior. Needless to say I wont have to manualy upload images 1 by 1 to update product images for companies. used windows number before letters to have my script at end of the directory and when the image upload window pops up I have to use active accessibility to get the syslistview from the window and select the 2nd element which is a picture the 1st element is a folder. or the first element in a findfirstfile return only files call. I use the name to search for the item in a database of items and then access those items and update a few attributes after upload of images,then I move the file from that folder to a another folder so it doesn't get processed again and move onto the next first file in the list and loop until script name is found at the end of the update.
Just sharing how a lowly data entry person saves time, and fights all these evil form validation checks.
Regards.
This is a very short version that hasn't failed since it was implemented on my sites 4 years ago with added variances as needed over time. This can be built up with all the variables and if else statements that you require
function spamChk() {
var ent1 = document.MyForm.Email.value
var str1 = ent1.toLowerCase();
if (str1.includes("noreply")) {
document.MyForm.reset();
}
<input type="text" name="Email" oninput="spamChk()">
I had actually come here today to find out how to redirect particular spam bot IP addresses to H E L L .. just for fun
Great ideas.
I removed re-captcha a while back converted my contactform.html to contactform.asp and added this to the top (Obviously with some code in between to full-fill a few functions like sendmail, verify form filled out completely etc.).
<%
if Request.Form("Text") = 8 then
dothis
else
send them to google.com
end if
%>
On the form i stuck a basic text field with the name text so its just looks like anything not specifying what its for at all, I then stuck some text 2 lines above in red that states enter what 2 + 6 = in the box below to submit your request.
I have a client whose website I created with Wordpress. It has a contact form created with contact form 7. This client is a subsidiary of a larger organization who's IT department runs scans on their subdomains. The asked my client to protect Contact Form 7 from malicious scripts or take it down.
When I asked for an example of what they tested, my client informed me that they run tests to see if a script could be inserted into a input (ie: <script>alert('hello');</script>) field or as a url string (ie: www.mydomain.com/contact?<script>alert('hello');</script>).
With the query string, the contact form sets the action to: action="/?scriptalert('hello');/script#wpcf7-f1-p6-o1". My first question would be, will this harm anything since the "<" and ">" has been removed from the string?
If so, is there anything I can add to remove the possibility of running scripts in this contact form?
HTML Encoding is one way to prevent any HTML/JS from taking effect. It's a good idea to encode any user-supplied value before displaying it in the page.
