I just want to change the background color on my simple site. But it's not only non functional, it's changing the background to red, even if i completly delete all coloring, restart XAMMP and delete the browser chache. I'm completly clueless. And yes.. I know that the code is not efficient, but it was my task to do it that way.
<html>
<head><title>Switch</title></head>
<body>
<p><div id="main">
<meta charset="utf-8"/>
<?php
$Uhrzeit = date("H");
echo '<body style="background-color:blue" />'; //Even set the color outside the if-statement
if($Uhrzeit > 6 && $Uhrzeit <= 12){
echo '<body style="background-color:blue" />';
}
elseif($Uhrzeit > 12 && $Uhrzeit <= 18){
echo '<body style="background-color:blue" />';
}
elseif($Uhrzeit > 18 && $Uhrzeit < 6){
echo '<body style="background-color:black" />';
echo '<body style="color:white" />';
}
$select = $_POST["Monat"];
switch($select){
case "Januar":
echo $select . " hat 31 Tage";
break;
case "Februar":
echo $select . " hat 28 Tage";
break;
case "März":
echo $select . " hat 31 Tage";
break;
case "April":
echo $select . " hat 30 Tage";
break;
case "Mai":
echo $select . " hat 31 Tage";
break;
case "Juni":
echo $select . " hat 30 Tage";
break;
case "Juli":
echo $select . " hat 31 Tage";
break;
case "August":
echo $select . " hat 31 Tage";
break;
case "September":
echo $select . " hat 30 Tage";
break;
case "Oktober":
echo $select . " hat 31 Tage";
break;
case "November":
echo $select . " hat 30 Tage";
break;
default:
echo $select . " hat 31 Tage";
break;
}
?>

CodePudding user response:
There should be only one body
tag in the HTML document. You are printing many, so that's the issue. Instead of echo '<body...'
you could store the color in a variable and print it in main body
tag.
Example:
<?php
$bgColor = 'blue';
if(something) {
$bgColor = 'red';
} else if (something) {
$bgColor = 'yellow';
}
?>
<html>
<head>
<title>Switch</title>
</head>
<body style="background-color: <?php echo $bgColor; ?>">
...
</body>
</html>
Or if you have short_open_tag enabled in php config, you could replace <?php echo $bgColor; ?>
with <?=$bgColor;?>
