Help building an evaluation system

Prosjeik · November 1, 2013

Hi.

I'm going to create a web-based system in php.

I wanna put 8 categorys, one on each row and behind each of them there will be 9 buttons.- to the right there vill be a 8x9 cells table.

When i press one button the value of that buttons variable will increase with 1.

After pressing the button im still at the same page still seeing all those buttons behind the categories. But the value to the button i just pressed will be shown in the table to the right.

I may press several buttons a hundred times and the table still show the value (value = how many time i press each button).

Can anyone help me on my way? I did work a lot with php for about 10 years ago, but i cant figure out how this could be done..

You need JavaScript for this.

<form action="" method="post">
  <input type="button" name="button1" value="1" class="increase-value">
</form>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
  $('.increase-value').click(function() {
    var $this = $(this);
    $this.val(parseInt($this.val(), 10) + 1);
    alert($this.val());
  });
</script>

Are you serious about having to click 72 buttons 100 times to give assessment scores of 100? And if you accidentally overshoot then go round again!

Why not text input or dropdowns? This code will give you dropdowns.

<?php
$categories = array(
        1 =>    'Category 1',
        2 =>    'Category 2',
        3 =>    'Category 3',
        4 =>    'Category 4',
        5 =>    'Category 5',
        6 =>    'Category 6',
        7 =>    'Category 7',
        8 =>    'Category 8'
        );
$criteria = array(
        1 =>    'Crit 1',    
        2 =>    'Crit 2',    
        3 =>    'Crit 3',    
        4 =>    'Crit 4',    
        5 =>    'Crit 5',    
        6 =>    'Crit 6',    
        7 =>    'Crit 7',    
        8 =>    'Crit 8',    
        9 =>    'Crit 9'    
        );
$tableHead = "<tr><th> </th><th>" . join('</th><th>', $criteria) . "</th></tr>\n";
$opts = '';
for($i=0; $i<=100; $i++) {
    $v = $i==0 ? '' : $i;
    $opts .= "<option value='$i'>$v</option>";
}
?>
