displaying color if rating

NickLindeman

I need help with a script to display a color if the rating is between a number range fetching it from the database.

For example if it's rated 4.00 and above it gets a red color and 3.00 to 3.99 gets a blue color.

Can anyone help me?

<?php

if ($score="4.00,5.00"){

echo " color='#0000FF'";

}

else {

echo "";

}

?>

I've tried using that but it instead displays everything in blue.

Well first of all, you're not even using a comparison operator, such as '=='. Instead, you're saying "if you can change the value of $score to be the string '4.00,5.00', do this..".

Secondly, I'm not sure what the comma notation is for... if you're trying to test if it's in between two numbers, then do that:

if($score >= 3.00 || $score <=3.99)
    echo "...";
elseif($score >= 4.00)
    echo "...";

Alright I did..

<?php

if($score >= 4.00)
    echo " color='#0000FF'";
elseif($score >= 3.00 || $score <=3.99)
    echo " color='#FF0000'";
elseif($score >= 0.00 || $score <=2.99)
    echo " color='#FF00FF'";

?>

It displays the red and blue but not the last purple.

What am I doing wrong?

Oops, wasn't thinking - use the && operator in those if() statements.

Eventhough is resolved already.

Nick,
here is fun script, where I use [man]switch[/man] and [man]floor[/man]
to put 5 colors to score levels.

A randomize loop for testing scores and displaying in colors.

<?php
// Script by halojoy
// October 2007

// Create 40 random test values, 0.00-5.00
for($i=0; $i<40; $i++){
    $score = rand(0,500)/100;

// $test = round $score downto integer
$test=floor($score);
switch($test){
    case  5:
    case  4: $col="#ff6600";break; //red
    case  3: $col="#0099ff";break; //blue
    case  2: $col="#ffff66";break; //yellow
    case  1: $col="#66ff66";break; //green
    default: $col="#cccccc";       //grey
}

// Display each $score in 5 different color backgrounds!
echo '<span style="font-size:10px;background-color:'.$col.'">';
echo $score;
echo '</span>';
echo '<br />';
}

?>
