Hi guys, I need help a client of mine would like a call calculate that generates average savings depedning on the data input into the form.
The following Code is For the First Page which contains the form.
<?php function callcalc_form() {
$form = array();
$text = '<p><img src="/files/landlinetomobile/images/bigcalculator_0.jpg" alt="Calculator" title="calculator" align="right" hspace="10px" vspace="10px" width="250" height="235" />Centralcom are dedicated to saving companies however large or small money on their calls to mobile numbers.<br/><br/></p>

$form['text'] = array(
'#type' => 'item',
'#value' => $text,
);
$form['minutes'] = array(
'#type' => 'textfield',
'#title' => t('Monthly Minutes'),
'#decription' => t('Monthly minutes used calling mobiles in minutes'),
'#size' => 10,
);
$form['spend'] = array(
'#type' => 'textfield',
'#title' => t('Monthly Spend'),
'#decription' => t('Monthly spend on calls to mobiles in pounds(£)'),
'#size' => 10,
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Calculate'),
);
return $form;
}
function callcalc_form_validate($form_id, $form_values) {
if (empty($form_values['minutes']) || !is_numeric($form_values['minutes'])) {
form_set_error('minutes', t('Please enter a numerical value'));
}
if (empty($form_values['spend']) || !is_numeric($form_values['spend'])) {
form_set_error('spend', t('Please enter a numerical value'));
}
}
function callcalc_form_submit($form_id, $form_values) {
$minutes = $form_values['minutes'];
$spend = $form_values['spend'];
//echo $minutes;
//echo $spend;
//First Total - Price per minute
$ppm = $spend / $minutes;
//echo $ppm;
//Second Total - minus 0.05 from ppm
$minus = 0.05;
$second_total = $ppm - $minus;
//echo $second_total;
//Third Total - Monthly saving - second total * total minutes
$third_total = $second_total * $minutes;
if ($third_total < 0) {
$third_total = 0;
}
//echo $third_total;
//Fourth total - Annual saving - third total * 12
$fourth_total = $third_total * 12;
//echo $fourth_total;
}
?>
The action for the form is ( <form action="callcalc2.php?'third=$third_total&fourth=$fourth_total" accept-charset="UTF-8" method="post" id="callcalc-form">)
This then takes me to callcalc2.php on this page the only php i have is;
<?php
$third_total = $_POST['third'];
?>
Then
<?php echo $third_total; ?>
which dosent display the calculated value, as you can tell I dont know a huge amount about PHP any help would be hugly welcome
you can see the example on http://www.mking-designs.com/test/callcalc.php
