Why does this show 2?

pavankat · March 21, 2012

I can't understand for the life of me - why the value for the variable: $total_vit_k is 2 in the red box: http://content.screencast.com/users/rockstarvisible/folders/Jing/media/beafff1f-2168-47b8-91bb-950ace0722c2/2012-03-21_1437.png.

The reason why I can't understand this is because $total_vit_k is the weekly total for everything from jan 29 to feb 4 but there's no values for those dates logged in the mysql table it's pulling from.

Please help me. It should be displaying 0 Mcg in the red box but it isn't. I know it's something wrong in my code.

When I echo out all the values in the while loop like below, the browser echos out nothing for the queries from jan 29 2012 to feb 4 2012.

code below is from file 2:

while ($row = mysql_fetch_assoc($query_run)){
                
echo "<br /><br /><b><i>" . '$sql_food ' . $sql_food."</b></i><br /><br/ >";
echo "<br /><br /><b><i>" . '$sql_total_servings ' . $sql_total_servings."</b></i><br /><br/ >";
echo "<br /><br /><b><i>" . '$sql_day ' . $sql_day."</b></i><br /><br/ >";
echo "<br /><br /><b><i>" . '$sql_month ' . $sql_month."</b></i><br /><br/ >";
echo "<br /><br /><b><i>" . '$sql_year ' . $sql_year."</b></i><br /><br/ >";
echo "<br /><br /><b><i>" . '$sql_vit_k ' . $sql_vit_k."</b></i><br /><br/ >";

echo "<br /><br /><b><i>" . ' $sql_servings ' .  $sql_servings."</b></i><br /><br/ >";
echo "<br /><br /><b><i>" . ' $total_vit_k ' .  $total_vit_k."</b></i><br /><br/ >";
  include 'inside_while.acc-over.php';
        }

The output in the screenshot doesn't match up with the code you've posted.

Thanks for taking the time to look at this.

It's too long to take a screen shot with all that's being echo'd so I made a video:

http://screencast.com/t/w9gditjXz

At 1 minute and 8 seconds you'll see the calendar and you'll see in the Weekly Vit K Total first box has v k: 2 Mcg where it should be v k: 0 Mcg.

Please help me. Would mean the world.

$query_day . "=calendar_day && ".$query_month."=calendar_month && ".$byear."=calendar_year

these are the wrong way round, you have the value on the left of the = and the field on the right, should be field on left and value on right.

  $query_value3 = "SELECT 
foods.id, users_calendar.id, `name`, `source`,`vit_k`, `cal`,`protein`, `fiber`, `carbs`, `sugar`, `sodium`, `chol`, `total_servings`,
`calendar_month`, `calendar_day`, `calendar_year`, `servings`
FROM `foods`
LEFT JOIN users_calendar
ON foods.id=users_calendar.food_id
WHERE ((users_calendar.user_id ={$_SESSION['user_id']}) && (calendar_day=$query_day) && (calendar_month=$query_month) && (calendar_year=$byear))
ORDER BY users_calendar.id";

Thanks Muddy but that wasn't it. That surprisingly didn't change anything - I guess it's improper syntax what I did in the query but that doesn't change the query's purpose.

I got it to work with the help of a friend pointing out where the code was broken.

I changed: $day_temp = $days_in_month;

to:

if ($bmonth < $emonth){

$day_temp = $days_in_month;

}else{

$day_temp = $eday;

}
