With the stock version of the yii2 captcha, if I click on the captcha image it will refresh the image ... for example if I can't read the first image.
But it doesn't seem to change the actual code, so that when I submit the form, the captcha variation fails.
What might I be doing wrong?

I faced with a strange problem. I write ASP.NET web application.
I have form tag on the aspx page and submit in the form. When I click on the submit form's data are posted. It is ok. But if I close the page right after submit and then re-open it with Main Menu -> Recent Tabs (I use Google Chrome) the form's submit fires once again and data are posted too. I would like to avoid this behavior because repeated posting data to server is unwelcome and unexpected. It happens after select Recent Tabs only (when I prress Ctrl+Shift+T it does not happen) How could I prevent it? Thanks in advance
Check if it's a PostBack. If it is a PostBack then return.
I have a form on a webpage that submits post information to the server. All is working good except when i submit the form and press back button the data in the form re-appears instead of going to the previous web page. How can I prevent this? Also I want the previous web page to be reloaded again when i press back button.
Thank you.
I'm confused about how Chrome decides what forms to autofill. By autofill I mean the inputs are highlighted in yellow and already completely filled in when you land on the page (see picture below). I do not mean autocomplete which is where the input is blank and you get a suggestion only when you start typing in it.
Here's the autofill rules as I understand them:
If your form is located on its own url, e.g., http://mysite.com/login
Your form is present on page load and is NOT loaded via ajax
Comparing my site with Dropbox's we both have a login page: http://localhost/login vs. https://www.dropbox.com/login which satisfies rule #1. The login form gets autofilled for both of us.
My problem is with rule #2. On Dropbox's homepage, www.dropbox.com, they have a "sign in" modal (see picture below) that gets autofilled. On my homepage, http://localhost, I have an identical modal which does NOT ever get autofilled.
I can't figure what the deal is here, can someone chime in? Is it just a localhost vs. real URL issue? If so, how do you explain why http://localhost/login gets autofilled?
When you log into a new site chrome will drop down its notification bar at the top and ask you if you want to save the password, if you tell it "Never" it wont ask again and it wont ever autofill

How to trigger Autofill in Google Chrome?,
I have a form which uses post method to post the data. On the action page, i receive the data.
If i refresh the page , it ask that Information you have to enter again(in chrome) and if I click on continue it gets the same post data and works properly. However if on the same action page, I click on address bar and press enter, data is lost.
How can I handle that?
you can't.
hitting enter in the address bar will result in a GET request.
when you refresh the page the browser will resend your last request that's why it asks if you are sure to POST again.
Say if I am on page 1 , I enter my form data and go to page 2 , But wait I forgot something and I need to go back. FireFox and Safari ask me if I want to resend my form data.
But IE being IE it just goes back and does not show the page.
Is there away around this when I click back it keeps the data and the page appears.
Sorry I cannot give a link but the process for u to go through on my site to get to this part would take you a while.
My suspicion is that your talking about a wizard form. Where each part of the form is a page and you can go backwards and forwards through the pages.
the back button has always caused problems for developers on the web and this is probably the most annoying.
You can stop the IE back button issue by redirecting on the server to the next page when you receive a form post rather than just delivering the form back to the browser. Doing this means that the browser considers each page to have been a get and stops asking you if you want to resubmit the form.
to do this simply make each form post to itself and then return a redirect to the next page of the wizard. I'd give examples but I'm not sure what language you are using on the server.
the other alternative is to use javascript to create a wizard from your form see this jQuery wizard form demo.
create a new back button besides the submit button and when a user clicks on either one you call a javascript function which modifies the form action either to the next page or the previous page.
