submit, whitelist value as selected

[bwakad]

- EDIT - if I just use plain old html and php (no function) I can simply say $input->post->my-field-variable in the $selected = ... etc.

I guess a function to output a select is not a good idea if you want to retrieve back it's value... - END EDIT -

I don't know if this is good practise but I made this function so I could simply use: select("myfield"); in my template, which make the code less. Just a reminder, the "select" word I use here is just to make it clear.

I use these on a form submit, posting to the same page, and errors get displayed for empty values etc. But I would like to retrieve back the value selected in a select to make it more user friendly. I thought it was the whitelist doing that, but noooo... I tried with input->post->what and no result either.

I use this for error checking...

$myfield = $input->post->myfield;

function select($what) {
$pages = wire("pages");
$out =        "<select name='{$what}' id='{$what}' aria-label='{$what}' required>
            <option value=''>your {$what}</option>";            
            foreach($pages->get("/personal-info/{$what}/")->children() as $what) {
$out .=        $selected = $what->name == $input->whitelist->what ? " selected='selected' " : '';
$out .=        "<option$selected value='{$what->name}'>{$what->title}</option>";
            };

$out .=        "</select>";

echo $out;
}

$selected should not be added to $out .=
