I need some advice again. How would you go about a problem like this?


I have a form that I put through a validation process. There are three fields. If the validation fails, the form displays an error and the user has a chance to correct it. That means whatever he typed into the fields will stay there so he doesn't have to re-type everything again.


Now my problem is that once the form is validated and successfully submitted, the fields still show the text typed in by the user. I need them to be blank again after a successful submission. How do I do that?


This is how I keep the user input in the form. The unset attempt seems to have no effect and doesn't clean the input:

PHP Code:

<?php
 $formname = htmlentities(stripslashes($_POST['name']));
 

 // some more code including validation
 // if validation is successful then
 $allgood = “ok”;
 

 // Unset attempt
 if (isset($allgood)) {
 unset($formname);
 }
 ?>
 <form action="form.php" method="post" name="comment" id="captcha-form" >
 <input name="name" id="name" type="text" size="30" maxlength="20" value="<?php echo $formname; ?>" />
 *
 *
 *
 *
 </form>

$formname="";

I tried that already. It didn't work but I have realised in the meantime that my $allgood variable doesn't get set properly because my script can't really tell if all the conditions have been met all at the same time.

To remedy that, now every validator condition adds a value to an array. I need a script to check if there is an instance of “no” in the array. If there is none then the $allgood gets set to “ok” otherwise $allgood = “no”. I've figured out a way of doing it but as usual, it doesn't work. I'm just trying to create a working script. If I'm successful I'll post it here.

My array is called $data and here is the print_r output in case anyone wants to have a go:

Array ( [0] => no [1] => no [2] => yes [3] => no [4] => yes [5] => no [6] => yes [7] => no [8] => yes [9] => no )


This form is really giving me headache.

I've got it! This is what I've done:

PHP Code:

<?php
   if (in_array("no",$data)) {
         $allgood = false;
     } else {
         $allgood = true;
         }
 

 $formname = htmlentities(stripslashes($_POST['name']));
  // same thing for all other input variables

  if ($allgood == true) {
     $formname = "";
     // same thing for all other input variables
  }
 ?>

I had to place it between the form and the last validation part that was adding a value to the $data array. The placement was a major issue, which I didn't address before. I've altered my whole form so there is no validation PHP code in it. The CAPTCHA validation part of my form was inside the <form> tags and the $allgood value didn't make it further than the end of my script. On every validation failure, as the form got re-loaded, the $allgood lost it's value and the condition had no effect. Now all the fields are cleared if the form is successfully submitted.


Only took me half a day lol
