Sum Values From Different Columns
0
I am having problem adding up the values in a column with php.
These values where sent from checkboxes and i want to count only the values that where checked from the unit column.
Here is my code:
<?php
$id = $_POST['course'];
foreach($id as $value)
{
//echo $value;
$query = " SELECT * FROM french WHERE id= $value ";
$result = mysql_query($query) or die('Error, query failed');
while ($row = mysql_fetch_array($result)) {
$id = $row['id'];
$course = htmlspecialchars($row['course_name']);
$code = htmlspecialchars($row['course_code']);
$unit = $row['unit'];
$status = $row['status'];
?>
php sum

I'm not sure if this is an error when you copied your code into this post, but you seem to have left out the closing brackets for both of the loops.

Are you trying like this? Getting form array of form checkboxs and checking on database via ID's?
HTML FORM
Check 1 <input type="checkbox" name="val" />
Check 2 <input type="checkbox" name="val" />
PHP RESULT
$val = $_POST['val'];
$count = count($val);
foreach ($val as $val_res)
$query = 'SELECT * FROM french WHERE id='.$val_res;
