Hello, I have a script that displays data from a XML file into a table and it works great. What I want to do is try to set a background color to a table cell based on the report element it gets from the XML file. I have another script I have done this for and it works great. For some reason I can't seem to get it working with this script.

 

Here is a working page of what it should look like. If you look below the map the tables have different backgrounds depending on the report.

Here is the actual page I am trying to get it to work on and the code I am using below.

 }

//If no storms were in the source, set no storm message
if(!$tData)
{
    $tData = $noStormMessage;
}

echo $tData;

?>

It should take this code to assign the colors....

$stormTypesAry = array(
    'tornado' => 'Tornado',
    'funnelcloud' => 'Funnel Cloud',
    'wallcloud' => 'Wall Cloud',
    'rotation' => 'Rotation',
    'hail' => 'Hail',
    'wind' => 'Wind',
    'flood' => 'Flood',
    'flashflood' => 'Flash Flood'
);

$reportColor = '';

           switch($stormTypesAry)
{
              case 'Tornado':
                    $reportColor = 'rgba(128, 128, 128, 0.4)';
                              break;
              case 'Funnel Cloud':
                    $reportColor = 'rgba(255, 222, 173, 0.4)';
                              break;
              case 'Wall Cloud':
                    $reportColor = 'rgba(255, 20, 147, 0.4)';
                              break;
              case 'Rotation':
                    $reportColor = 'rgba(255, 228, 181, 0.4)';
                              break;
              case 'Hail':
                    $reportColor = 'rgba(255, 255, 0, 0.4)';
                              break;
              case 'Wind':
                    $reportColor = 'rgba(255, 0, 0, 0.4)';
                              break;
              case 'Flash Flood':
                    $reportColor = 'rgba(255, 165, 0, 0.4)';


}

Then assign the table color style like so...

$td4Style = "{$sbrdr}; {$bbrdr}; padding: 2px 6px 6px 6px; background-color:{$reportColor};";

What am I missing or overlooking?

 

-Thanks

Hello, I have a script that displays data from a XML file into a table and it works great. What I want to do is try to set a background color to a table cell based on the report element it gets from the XML file. I have another script I have done this for and it works great.

    $tData .=  $afterTable;

 }

//If no storms were in the source, set no storm message
if(!$tData)
{
    $tData = $noStormMessage;
}

echo $tData;

?>

It should take this code to assign the colors....

$stormTypesAry = array(
    'tornado' => 'Tornado',
    'funnelcloud' => 'Funnel Cloud',
    'wallcloud' => 'Wall Cloud',
    'rotation' => 'Rotation',
    'hail' => 'Hail',
    'wind' => 'Wind',
    'flood' => 'Flood',
    'flashflood' => 'Flash Flood'
);

$reportColor = '';

           switch($stormTypesAry)
{
              case 'Tornado':
                    $reportColor = 'rgba(128, 128, 128, 0.4)';
                              break;
              case 'Funnel Cloud':
                    $reportColor = 'rgba(255, 222, 173, 0.4)';
                              break;
              case 'Wall Cloud':
                    $reportColor = 'rgba(255, 20, 147, 0.4)';
                              break;
              case 'Rotation':
                    $reportColor = 'rgba(255, 228, 181, 0.4)';
                              break;
              case 'Hail':
                    $reportColor = 'rgba(255, 255, 0, 0.4)';
                              break;
              case 'Wind':
                    $reportColor = 'rgba(255, 0, 0, 0.4)';
                              break;
              case 'Flash Flood':
                    $reportColor = 'rgba(255, 165, 0, 0.4)';


}

Then assign the table color style like so...

$td4Style = "{$sbrdr}; {$bbrdr}; padding: 2px 6px 6px 6px; background-color:{$reportColor};";

What am I missing or overlooking?

 

-Thanks

 

 

I may stand corrected here but at least one issue is that you are trying to pass an entire array to your switch statement, which as far as I am aware isn't possible. A switch usually takes a single value to evaluate against. 

 

So you might want to do a foreach statement and run the switch in a function that can be called on each iteration.

i have a recommendation for using a switch/case statement to map one value to another, especially since you already have an array that is mapping one value to another.

 

don't use a switch/case statement to map one value to another, just expand your existing array. this will significantly reduce the amount of code and will point out things like missing values (your posted code doesn't handle  the 'flood' value for $typeKey.)

 

your array -

$stormTypesAry['tornado'] = array('name' => 'Tornado', 'color' => 'rgba(128, 128, 128, 0.4)');
$stormTypesAry['funnelcloud'] = array('name' => 'Funnel Cloud', 'color' => 'rgba(255, 222, 173, 0.4)');
$stormTypesAry['wallcloud'] = array('name' => 'Wall Cloud', 'color' => 'rgba(255, 20, 147, 0.4)');
$stormTypesAry['rotation'] = array('name' => 'Rotation', 'color' => 'rgba(255, 228, 181, 0.4)');
$stormTypesAry['hail'] = array('name' => 'Hail', 'color' => 'rgba(255, 255, 0, 0.4)');
$stormTypesAry['wind'] = array('name' => 'Wind', 'color' => 'rgba(255, 0, 0, 0.4)');
$stormTypesAry['flood'] = array('name' => 'Flood', 'color' => 'you don\'t have an entry for this');
$stormTypesAry['flashflood'] = array('name' => 'Flash Flood', 'color' => 'rgba(255, 165, 0, 0.4)');

getting both values at once, without writing line after line of hard coded logic for each value -

// get the stormType and reportColor using the $typeKey
$stormType = $stormTypesAry[$typeKey]['name'];
$reportColor = $stormTypesAry[$typeKey]['color']; // this line takes the place of all the switch/case logic

also, by having less code, it will be easier to see the errors in your logic.
