They remain in the fields because you are explicitly telling PHP to fill the form with the submitted data.

<input name="firstname" type="text" placeholder="First Name" required="required" 
value="<?php echo $_POST['firstname'];?>">
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ HERE

Just remove this, or if you want a condition to not do so make a if statement to that echo or just cleanup the $_POST fields.

$_POST = array(); // lets pretend nothing was posted

Or, if successful, redirect the user to another page:

header("Location: success.html");
exit; // Location header is set, pointless to send HTML, stop the script

Which by the way is the prefered method. If you keep the user in a page that was reached through a POST method, if he refreshes the page the form will be submitted again.

I was just trying to fix same error  I finally fixed it  so I will copy to you part of the code  maybe it helps you    lt input type  text  name  usu  id  usu  value   lt  php echo  usu   gt    gt  lt  input gt   lt input type  text  name  pass  id  pass  value   lt  php echo  varpass   gt   gt  lt  input gt      those are the inputs I wanted to clean after pressing my button   And here php code    query   INSERT INTO usuarios  tipo  usuario  password  VALUES      vartipo         usu         varpass                 if   mysqli query  conexion  query                 die  Error      mysqli error  conexion                       else                 usu                      varpass                       result     lt div class  result ok  gt El usuario se ha registrado con   xito   lt div gt                           usu        varpass        those are the lines that cleans the inputs  D

After submitting the post you can redirect using inline javascript like below  echo   lt script language  quot javascript quot  gt window location href  quot  quot  lt  script gt                   I use this code all the time to clear form data and reload the current form  The empty href reloads the current page in a reset mode

Put the onClick function in the button submit    lt input type  text  id  firstname  gt   lt input type  text  id  lastname  gt   lt input type  submit  value  Submit  onClick  clearform       gt    In the  lt head gt   define the function clearform    and set the textbox value to      function clearform         document getElementById  firstname   value       don t forget to set the textbox id     document getElementById  lastname   value         This way the textbox will be cleared when you click the submit button

I was facing this similiar problem and did not want to use header   to redirect to another page   Solution    Use   POST   array    to reset the   POST array at the top of the form  along with the code used to process the form   The error or success messages can be conditionally added after the form  Hope this helps

If you want your form s field clear  you must only add a delay in the onClick event like    lt input name  submit  id  MyButton  type  submit  class  btn-lg  value  ClickMe  onClick  setTimeout  clearform     2000      onClick  setTimeout  clearform     1500       in 1 5 seconds its clear  document getElementById  name   value         lt  lt  lt  lt  lt  lt just correct this document getElementById  telephone   value           lt  lt  lt  lt  lt correct this   By clearform    I mean your clearing-fields function

The POST data which holds the submitted form data is being echoed in the form  eg      lt input name  firstname  type  text  placeholder  First Name  required  required   value   lt  php echo   POST  firstname     gt       Either clear the POST data once you have done with the form - ie all inputs were ok and you have actioned whatever your result from a form is  Or  once you have determined the form is ok and have actioned whatever you action from the form  redirect the user to a new page to say  all done  thanks  etc     header  Location  thanks php    exit      This stops the POST data being present  it s know as  Post Redirect Get   http   en wikipedia org wiki Post Redirect Get    The Post Redirect Get  PRG  method and using another page also ensures that if users click browser refresh  or back button having navigated somewhere else  your form is not submitted again  This means if your form inserts into a database  or emails someone  etc   without the PRG method the values will  likely  be inserted emailed every time they click refresh or revisit the page using their history back button
