Question

I think I’m doing this wrong but this is what I have…

if($_GET['color']) {
    $color = "signature_";
echo "<img src=\"/images/+ $color \"; \"class=\"border\" alt=\"\" />";

What I’m trying to do is output the colored image based on the users input.

So say this is what I am doing.

Http://somedomain.com/index.php?username=Ultima&color=red.

So far I am displacing usernames properly, but images are not working.

I used “signature_” as a prefix because the image colors are all prefixed with that.

The images I’m trying to display upon input:

signature_red.png
signature_green.png
signature_white.png
signature_yellow.png
signature_gold.png
signature_silver.png
signature_purple.png
signature_pink.png

I’m not sure what I’m doing wrong with my code… but does anyone know how I could display the proper images upon url input using $get['color']?

Answer 1

$g=$_GET['color'];
if(in_array($g, array('red', 'pink', 'yellow' etc...))) {
    $color = "signature_".$g.'.png';
    echo '<img src="/images/'. $color.'" class="border" alt="" />';
}

Or something like that. You have to replace the “etc…” part.
Never put GET params into string without some check.
