form validation with dynamic content

hi , so i have this one page makeFromTemplate.php ,that includes new page if neccesary based on the url

<div >
<h1 >text</h1>
<ul class="subjects">
  
    <li><a href="makeFromTemplate.php?page=PAGE2" class="subject" >text</a></li>
    <li><a href="makeFromTemplate.php?page=PAGE3" class="subject">text</a></li>
    <li><a href="makeFromTemplate.php?page=PAGE4" class="subject">text</a></li>
     <li><a href="makeFromTemplate.php?page=PAGE5" class="subject" >text</a></li>
     <li><a href="makeFromTemplate.php?page=PAGE2" class="subject" >text</a></li>
    <li><a href="makeFromTemplate.php?page=PAGE3" class="subject">text</a></li>
    <li><a href="makeFromTemplate.php?page=PAGE4" class="subject">text</a></li>

    </ul>
</div>


<div id="loadedContent">

 
<?php 
   if (isset($_GET ['page'])) {
       $p = $_GET ['page'];
     
      if(file_exists('PAGES/'.$p.'.php')){
       include 'PAGES/'.$p.'.php';
      }

      }
   ?>
</div>

PHP:

then for example i have included the PAGE2.php and its content (see next code) shows in the makeFromTemplate.php and everything is ok

<form action="http://localhost/makeFromTemplate/makeFromTemplate.php" name="foorm" method="GET">
<input type="text" autocomplete="off" name="answer1"><br>
<input type="text" autocomplete="off" name="answer2"><br>
<input type="text" autocomplete="off" name="answer3"><br>
<input type="text" autocomplete="off" name="answer4"><br>
<input type="submit" name="roll" value="Make">


</form>


<?php


if(isset($_GET['answer1'])&&isset($_GET['answer2'])&&isset($_GET['answer3'])&&isset($_GET['answer4'])){
    $answer1=$_GET['answer1'];
    $answer2=$_GET['answer2'];
    $answer3=$_GET['answer3'];
    $answer4=$_GET['answer4'];


                if(!empty($answer1)&&!empty($answer2)&&!empty($answer3)&&!empty($answer4)&&!empty($answer5)&&!empty($answer6)&&!empty($answer7)&&!empty($answer8)){


                        $output= "Welcome $answer1 and $answer2 you all are my friends";
                        echo $output;
                      
                }else{
                    echo "fill all fields,my friend!";
                }
}
?>

PHP:

but what i want is that
1) include new page in makeFromTemplate.php (that works)
2) echo $output variable in makeFromTemplate.php page from dynamically added page. (DOESNT WORK)

forms action is falsy - because i dont know what to put there .

when i include the page based on url everything is great and url is
localhost/makeFromTemplate/makeFromTemplate.php?page=PAGE2

but after i submit the form url is
localhost/makeFromTemplate/makeFromTemplate.php?answer1=answer1&answer2=answer2&answer3=answer3&answer4=answer4&roll=Make


can you help me?

 

Input tags don't need to be closed in HTML 4. And the versions that require them to be closed, do it like this: <input />

Inputs with the type "submit" will submit the form without Javascript. So adding the onclick event is completely redundant. Plus, it should be submit() as it's a method, and not a property.

The maxlength attribute servers no security purpose because it can be removed by the user.

Literally everything you suggest is a bad advice.

 

Literally everything ezprint2008 has posted the last couple of days are complete crap advice, or bad coding. Be aware, I say. Might be just too little understanding, or it might be malicious - I dunno.
