Question

I have the following in my < head > section

<?php
$rand = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f');
$color = '#'.$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)];
?>

I have the following in my < body >

<div class="featured-details" style="background-color: <?php echo $color; ?>;">

When my page loads, the CSS says the following:

<div style="background-color: ;" class="featured-details">

i.e. it would seem no color is being generated.

Can anyone help?

Answer 1

It could be that your code snippet in your head is executed in a different scope than the code in your body and thats why $color is blank

if $color is in a function try making it a global variable instead.

You would need to add global $color; before you set it in the head and also at some point in the body.
