New to PHP programming. This assignment is for one of my college classes.

Goal:

How do I break the boxes so each one of them are on separate lines?

[ Register or Signin to view external links. ]

Using XAMPP

Here is the code that I currently have:







<?php


    $num_boxes = 4;


    $precision = 1;


    $gradetext = '';


                    //minimum=>grade


    $grade_array = array(


                    '90-100'=>'A',


                    


                    '80-89'=>'B',


                    


                    '70-79'=>'C',


                   


                    '60-69'=>'D',


                    


                    '0-59'=>'F'


                    );


function create_form($num_boxes=1)


{


    if(is_int($num_boxes))


    {


        $form = '';


        for($i=0;$i<$num_boxes;$i++)


        {


            $inc = $i+1;


            $val = (isset($_POST['grade'][$i])) ? $_POST['grade'][$i] : '';


            $form .= "<label for='grade$inc'>Grade $inc:</label><input id='grade$inc' name='grade[$i]' type='number' value = '$val' min='0' max='100' />"; 


        }


        return $form;


    }


}


function get_grade($pc,$grade_array)


{


    foreach($grade_array as $min=>$grade)


    {


        if($pc < $min) continue;


        return $grade;


    }


}


if($_POST)


{


    $GPA = 0;


    $num_posts = count(array_filter($_POST['grade'], "is_numeric"));


    $total = array_sum($_POST['grade']);


    if($num_posts != 0) $GPA = $total/$num_posts;


    $lettergrade = get_grade($GPA,$grade_array);


    $gradetext = "Average Test Score = " . number_format($GPA,$precision) . " ($lettergrade)";


}


?>


<!DOCTYPE HTML>


<html>


<head>


<meta charset="utf-8">


<title>Test Score Calculator</title>


</head>


<center>


<body>


<?php echo $gradetext;?>


<form method="post">


    <?php echo create_form($num_boxes);?>


    <input type="submit" value="Calculate" />


</form>


</body>


</center>


</html>

That is not a problem, that is a goal. So what is your problem? You don't know how to finish your solution? You have all the hard work done, now all you need to do is find a way to print out the result!

You also misspelled filter_input.

Steps..
1) Check if the POST request is set (or see if someone made a post request). (If statement)

1.1) Yes someone made a post request (submitted form). Normally you would clean the input then validate the input but since this seems like a school project I won't cover it. Anyways, now you have to solve your problem. Basic logic means you calculate the grade. The formula for your example is (x1+..+x4) / ( 400). Basic php math.

1.2) Simply echo it. *Check PHP manual.

AKA move this

Answer: <?php echo ($testscore1 + $testscore2 + $testscore3 + $testscore4);

inside the if statement or else you will end up with errors.

2) If No then just do nothing. The program will show the table.

<br> is what you're looking for.

It's not "proper", but just change

$form .= "<label for='grade$inc'>Grade $inc:</label><input id='grade$inc' name='grade[$i]' type='number' value = '$val' min='0' max='100' />";

$form .= "<label for='grade$inc'>Grade $inc:</label><input id='grade$inc' name='grade[$i]' type='number' value = '$val' min='0' max='100' /><br>";

Holy crap, thank you! Appreciate it.
