So, i'm developing a form that will be checked by a program to be executed with the data. How do you dump the data into a .json file with html forms or any other language?
For sake of the project i'll give a section of the html form to help understand.
<form action="/folder/data.php" method="post">
<div>
<label for="firstname">First Name:</label>
<input type="text" id="firstname" name="firstname">
</div>
<div class="button">
<button type="submit">Sumbit!</button>
</div>
</form>
