Column Sum - matt - 11-01-2017

Im trying to add up the values of a single column but failing.....

<?php

$query = $db->query("SELECT SUM (sendout) from sendouts");
$count = $db->count();
echo $count;
var_dump($count);
?>

Count gives you the number of rows returned in your query. Use $db->first(); to return the first row which is all you will have given you are only selecting the sum. Also, after this, you will need to have the column you want to output.

I would:
-Change your select to be SUM(sendout) AS Total (or whatever you want to call it)
-Make your $count = to $db->first()->Total;

Then you can echo it Smile

If you're still having a problem with this and getting your query right, you can do something like this.

Code:
$count = 0;

Code:
$query = $db->query("SELECT sendout FROM sendouts")->results();

Code:
foreach ($q as $sum){

Code:
$count = $count + $sum->sendout;

Code:
}

Code:
echo $count;

It's important to establish

Code:
$count = 0

outside of your foreach loop first.
