Question

I’m trying to get this piece of code working:

<?php
    $color_animation = $_GET['color_animation'];
 if ( $color_animation == "1" ) {
    echo "timer2 = setInterval(function() {
    $('.scar_box').animate( { backgroundColor: '#fee993' }, 1000)
    .animate( { backgroundColor: '#f8d95d' }, 1000); 
    }, 3000);";
}
  ?>

But it trows me the error: Invalid regular expression flag b

And: <b>Notice</b>: Undefined index: color_animation in <b>C:\xampp\htdocs\index.php</b> on line <b>117</b><br />

It doesn’t matter what i write into the $_GET it still has this problem.

Okay, I missed that bit. But you gave the answer away:

I don’t really know what does CLI means but i run it in the address bar like: ?main_text=Some Text&bgcolor=#8a7933&button_text=Some man&color_animation=on (The first $_GET which is main_text always works) – Ricardo 24 mins ago

The raw # separates the “fragement identifier” from the URL parameters. You need to use urlencode() in PHP or encodeURIComponent() for Javascript.

Or just use %23 in its place. (That’s the ASCII number equivalent for the # number sign.)
