Javascript to name 301a.js and put in /webroot/js

Helper Class:
<?php
/* colorpicker.php */
class ColorpickerHelper extends Helper {
function input($name,$label='') {
list($model,$fieldname) = split('\.',$name);
if (empty($label)) $label = ucwords($fieldname);
$str = '';
$str .= '<div class="input text colorpicker">';
$str .= '<label for="'.$model.$fieldname.'">'.$label.'</label>';
$str .= '<input name="data['.$model.']['.$fieldname.']" type="text" maxlength="7" value="'.$this->data[$model][$fieldname].'" id="'.$model.$fieldname.'" class="inputcolor" />';
$str .= ' <div class="samplebox" id="samplebox-'.$fieldname.'" onclick="showColorGrid3(\''.$model.$fieldname.'\',\'samplebox-'.$fieldname.'\');" style="background-color: '.$this->data[$model][$fieldname].'"> </div>';
$str .= '</div>';
return $str;
}
}
?>
Controller Class:
<?php
var $helpers = array('Colorpicker');
?>
View Template:
echo $colorpicker->input('Model.fieldname','Label');
CSS I added to my admin_style.css
.colorpicker .inputcolor {
width: 70px;
}
.colorpicker .samplebox {
border: 1px solid #000;
display: inline;
cursor: pointer;
}
