Updating Already Checked Checkboxes in PHP

Question

let\'s say I have a list of checkboxes that the user selects.

Water<         


        

Answer 1

What I've done in the past, to save having hundreds of lines of bloat is this...

First compile all the html in a variable, without any "checked" instances.

$boxes = '';
$boxes .= 'Water
';
$boxes .= 'Cable
';
$boxes .= 'Electricity
';

Now I loop over your array of fields to check. I've provided a sample array here too.

$already_checked = array('Water', 'Electricity');

foreach( $already_checked as $ac ) {
    $find = 'value="' . $ac . '"';
    $replace = $find . ' checked="checked"';
    $boxes = str_replace($find, $replace, $boxes);
}

echo $boxes;
