I'm stack in a php code that i want to find the total but i don't know what i did wrong and the total comes alway on "0".
My code like a order list. You check on what thing you need and how many do you want. You order it. It will apper how much the total cost
Here is my code:
The index code:
<form action="processorder.php" method="POST">
Nafn: <input name="nafn" type="text" size ="10"><br>
Kennitala: <input name="kennitala" type="text" size="10"><br>
Heimilisfang: <input name="heimilis" type="text" size="15"><br>
Netfang: <input name="netfang" type="text" size="10"><br>
Sími: <input name="simi" type="text" size="8"><br>
<table>
Vörur: <input name="vorur" type="hidden">
<tr>
<td></td><td>ID</td><td>Vörur</td><td>Verð</td><td>Magn/Verð</td><td>Magn</td>
</tr>
<?php
//Opna vorulist.txt skrá
$data = 'vorulist.txt';
$fp = fopen('vorulist.txt','rb');
$i=0;
//Lesa eina linu í einu
while(($line=fgets($fp)) !==false)
{
$list=explode(' ',$line);
echo '<tr><td>
<input type="checkbox" name="mychkbox'.$i.'" /></td>
<td><input type="text" name="myid'.$i.'" size="5" value="'.$list[0].'" readonly /></td>
<td><input type="text" name="myproductname'.$i.'" size="30" value="'.$list[1].'" readonly /></td>
<td><input type="text" name="myprice'.$i.'" size="5" value="'.$list[2].'" readonly /></td>
<td><input type="text" name="magn/verd'.$i.'" size="5" value="'.$list[3].'" readonly /></td>
<td><input type="text" name="magn'.$i.'" size="2" /></td>
</tr>';
$i++;
}
$size = $i;
echo '<input type="hidden" name="size" />';
?>
</table>
<br>
<input type="submit" value="Staðfest">
</form>
Here is the code on php:
date_default_timezone_set('UTC');
$nafn = $_POST['nafn'];
$kennitala = $_POST['kennitala'];
$heimilis = $_POST['heimilis'];
$netfang =$_POST['netfang'];
$simi = $_POST['simi'];
$heildarverd = 0;
//Lesa inn vorur
$size = $_POST['size'];
for($i=0;$i<$size;$i++)
{
$mychkbox =trim($_POST['mychkbox'.$i]);
$myid = trim($_POST['myid'.$i]);
$myproduckt = trim($_POST['myproductname'.$i]);
$myprice = trim($_POST['myprice'.$i]);
$mymagnverd = trim($_POST['magn/verd'.$i]);
$mymagn = trim($_POST['magn'.$i]);
//Tékka á checkbox is on or off
if ($mychkbox=='on')
{
$heildarverd = $heildarverd + ((int)$myprice)*((int)$mymagn);
$totalorder = $totalorder.$myid.' '.$myproduckt.' '.$myprice.' '.$mymagnverd.' '.$mymagn.'<br>';
}
}
//Sýna á vefinn
echo $totalorder;
echo 'Heildarverð: '.$heildarverd;
