Question

I’m running a query to have two columns in an html table.

 c.course_unit  
 m.score

In the m.score column, i want to do an if statement so that a point is awarded according to a certain range of the score. e.g

if ($row['m.score']  >= 70) {
point = 5;
 }

Then use each point awarded for each row multiplied with it’s corresponding values in the other column i.e (c.course_unit).

This is what i’ve been able to come up with so far, and IT’S NOT EVEN CLOSE TO IT.

I’ll most appreciate you sincere help.
Thank you.

$grade_point = 0 ;
while ($row =mysql_fetch_assoc($query)) {
    foreach ($row as $value) {
        if ($value >= 70) {
            $value['m.score'] = 5;
        }
        if ( $value['m.score'] >= 60 && $value['m.score']<= 69 ) {
            $value['m.score'] = 4;
        }
        if ( $value['m.score'] >= 50 && $value['m.score']<= 59 ) {
            $value['m.score'] = 3;
        }
        if ( $value['m.score'] >= 45 && $value['m.score']<= 49 ) {
            $value['m.score'] = 2;
        }
        if ( $value['m.score'] >=40 && $value['m.score']<= 45 ) {
            $value['m.score'] = 1;
        }
        if ($value['m.score'] < 40) {
            $value['m.score'] = 0;
        }

        $grade_point += $value['m.score'] * $value['c.course_unit'];
        echo "$grade_point";
    }
}

Just remove the foreach loop. Its iterating through your fields.

Here is the complete code that should work. I also change some variable name to fix it.

$grade_point = 0;
while ($row8 = mysql_fetch_assoc($query8)) {
    $marks = intval($row8['score']);
    if ($marks >= 70) {
        $score = 5;
    } elseif ($marks >= 60) {
        $score = 4;
    } elseif ($marks >= 50) {
        $score = 3;
    } elseif ($marks >= 45) {
        $score = 2;
    } elseif ($marks >= 40) {
        $score = 1;
    } else{
        $score = 0;
    }
    $grade_point+= $score * intval($row8['course_unit']);
    echo $grade_point;
}

Note.

1. For score 1 range should be from 40 to 44 (NOT 45) inclusively.
2. MySql result does not contain table alias in result set. So there is no ‘m.score’ Its just plain ‘score’. (Thanks to zerkms)
3. Using elseif code can be reduced. (Thanks to zerkms)
