  • When the internet connection is not proper.
  • A page that contains any form has been refreshed.
  • When you click the back button while being in the middle of form submission.

While filling any form where it is asking for your details then while the form is in middle of the submission you should not refresh or go back from the page.

As these resubmission form errors are quite annoying and time consuming. Therefore, we have researched and found out specific ways through which you can get rid of this problem of Confirm Form Resubmission Dialog Pop Up.

Method #1 Replacing the POST Method

POST and GET are the two methods that are used to post the data entered by the user in the form to the browser. When the post method is used, then the data entered by the user is not appended to the URL. On the contrary, whenever the GET method is used, then the data is added onto the URL, defying the confidentiality.

So the point is, the GET method is generally not the first choice. But in the case of form submission dialog you need check that if in your page you are allowed to modify data then, POST method should be changed to GET method. You can achieve that by following the following step.

In your URL, you need to remove the word ‘POST’ and replace it with the word ‘GET.’

Step 4: Close your Google Chrome. Re-open it with the same shortcut to see if the dialog box still appears on refreshing.

If you are using this method, then make sure that you have two shortcuts of Google Chrome. One with the changes that you made and the other one with the default properties. By this, you will be able to use the browser depending on your requirements.

Method #3 Disable Motion across the Browser

According to some resources, this Form resubmission Dialog popup arises again and again because the browser is unable to cache the POST request and tries to re-submits the form on refreshing. One of the main reasons behind this snag is continuous accidental forward and backward movements.

To resolve this issue, you can disable the motion buttons to prevent the browser from moving backward and forward. By this, if you accidentally press those buttons, even when the dialog box won’t pop up. If you have a touch screen device, then you can implement this by disabling the sliding option for forward and backward.

Method #7 Use the PRG Pattern to Fix Confirm Form Resubmission

Instead of using the only POST method, you can use PRG; it stands for POST/REDIRECT/GET. Mostly while making a form page we use POST only which increases the chances of the form resubmission error. PRG here eliminates those chances.

Whenever you create a form page, create one more page. It should have the sequence, form page, the other page and again the form page. So when you enter the details, it will go to the other page, process it there and then go to the server instead of directly sending the data to the server.

The user will only be seeing the form page because the action field of the form is this page and not the second page. Therefore, the last action that the browser will remember will be GET and not POST and thus, prevent the form submission dialog box from appearing on refreshing.

Method #8 Using AJAX Submit Button

If you add the AJAX function of jQuery, the form will not reload after its submission. For that, you need to add the below-given function in your page’s code.

$.ajax({
type: “POST,”
URL: “bin/validation.php.”
data: dataString,
success: function(){
//Whatever you want to do on successful submission
}
});
return false;

Here the Ajax () processes the data entered in the form as per to what the PHP file provided as the URL property. If the data is validated, it is considered as a successful form submission and thus, returns a false. So, even if the page is reloaded, it would not send any new request. Therefore, it will prevent the dialog box from popping up.

Method #9 Adding a Tag Inside <head> Part

One more way to remove this snag is if you can get access to the source code of the web page. Then, add the following tag to the head section of the page.

<meta http-equiv=”refresh” content=”60; write_the_url_of_the_page_to_be_tested_over_here.html” />

You need to add this very carefully onto the web page. This method can be implemented only when the website itself initiates the request, and the user pressed the refresh command.

Method #10 Delete No-Store to Fix Confirm Form Resubmission

You can also solve the issue if your form has the below-given text in your header field.

header(‘Cache-Control: no-store, no-cache, must-revalidate, max-age=0’);

If this is there in your header then, there is a possibility that the issue is with your header. You can follow the below-given steps to remove it.

Step 1: Try to delete ‘no-store’ from the header.

Step 2: Refresh the page within the form.

Step 3: Now re-enter the form and refresh the page to check if it has worked or not.
