Show divs based on the amount of arrays

Question

Here is my function

function yyy_hero_image_option_callback() {
$hero_options = get_option( \'hero_options\' ); 
$count=count($hero_options);
$totalimg=$coun         


        

Answer 1

The way you changed your code, $i is not set anymore, try this :

foreach ($hero_options as $key => $value) {
    if (strpos($key, '_zzz_')) {
        $i = substr($key, -1); // This will retrieve the last char of $key, which is corresponding to your previous $i
        $html = '
';
        $html .= '
';
        $html .= '  
-
';
        $html .= '
';
        $html .= '
';
        echo $html;
    }
} 

I also replaced the $hero_options[key] parts by $value, since you already get it from the foreach.
