Question

I’m trying to design a Form class in PHP. So far, I have the <input> buttons pretty well working. But the <select> boxes have me stymied. I’m trying to figure out a ‘generic’ way of adding the <option> tags, and am lacking the creativity.

I’m not asking for teh codez, but implementation ideas are welcome.

Answer 1

This is my implementation of it from my bare-bones framework that I use in super simple projects:

function select($name, $options = array(), $attrs = array(), $showEmpty = false) {     $attrs['name'] = $name;     $attrs['class'] = isset($attrs['class']) ? $attrs['class'] . ' input' : 'input';     if(isset($this->validation->invalid[$name])) {         $attrs['class'] .= ' errorinput';     }            $opts = array();     foreach($attrs as $key => $value) {         $opts[] = $key . '='' . $value . ''';        }     $htmloptions = array();     $hasSelected = false;     foreach($options as $option => $value) {         if(isset($this->validation->post[$name]) && $this->validation->post[$name] == $option) {             $hasSelected = true;             $htmloptions[] = '<option value='' . $option . '' selected>' . $value;           } else {             $htmloptions[] = '<option value='' . $option . ''>' . $value;                            }     }     if($showEmpty) {         $emptyoption = '<option value=''' . (($hasSelected) ? '' : ' selected') . '>';         $htmloptions = array_merge($emptyoption, $htmloptions);     }     return '<select ' . implode(' ', $opts) . '>' . implode('\n', $htmloptions) . '</select>'; }
