Prevent form resubmission on refresh

Http post: confirm form resubmission “the page the you

I have a clear form that sends text to my SQL database. The issue is that if the user refreshes the page after submitting the text, the data is submitted again without the user having to fill out the form again. I might send the user to another page after they submit the text, but I prefer that they remain on the same page.
You can really use the Post Redirect Get pattern for this, but if you’re in a situation where it isn’t possible (e.g. the form is in an include, preventing redirects), you should hash some of the request parameters to create a string based on the content and then verify that you haven’t already submitted it.
It’s a good idea to use the Post/Redirect/Get pattern from Keverw’s response. However, you are unable to remain on your page (and I believe this was your request?) Furthermore, it can sometimes fail:
You actually validate the user feedback on your POST page but do not act on it; instead, you copy it into a SESSION array. After that, you’re taken back to the main submission tab. Check to see if the SESSION array you’re using exists, then copy it into a local array and unset it on your main submission tab. You may then take action.

Data re-submit on page refresh issue in php | php crud

When you send data to a database using an HTML form, the data is inserted into the database; however, if you click the submit button again without entering any data into the input area, the same data will be stored in the database, and if you attempt to refresh the page, the same data will be inserted again. As a result, you’ll have duplicate data in your database, which can cause problems when reviewing or removing records.
If the user does not need to stay on the same page after submitting data, a PHP redirect feature that can automatically redirect the user to another page is a good way to avoid form resubmission on page refresh.
Replaces a single entry in the browser session history with history.replaceState().
This ensures that the data you submit will not be saved on your browser immediately after you send it, and you will have to send it again because the browser will not remember the first time it was there, preventing the form from resubmitting data on-page refresh.

Preventing post on reloading a form

First and foremost, in my approach, I ensure that each form input is properly received and saved by the database. If the attempt is successful, use the success feature to refresh the page without resubmitting the form by printing a PHP script, as shown below.
If the answer is successful, print the line below as a function called success to refresh the page without resubmitting the form after executing the code. The user cannot either resubmit the type inputs or rerun the code with the previous variables in this situation.
