Question

Don’t know if I worded the question right, but basically what I want to know is if there is an easier (shorter) way of doing the following:

switch( $type ) {
    case 'select': $echo = $this->__jw_select( $args ); break;
    case 'checkbox': $echo = $this->__jw_checkbox( $args ); break;
    case 'radio': $echo = $this->__jw_radio( $args ); break;
    case 'input': $echo = $this->__jw_input( $args ); break;
    case 'textarea': $echo = $this->__jw_textarea( $args ); break;
    default: return null;
}

Is there any way I could do something like $echo = $this->__jw_{$type}( $args );? I tried this code but of course, it failed. Any ideas?

Answer 1

$field = "__jw_$type";
$echo = $this->{$field}($args);

or even more simply,

$echo = $this->{"__jw_$type"}($args);
