Despite CakePHP already provided the powerful Scaffolding feature and the Bake code generator, also we need to understand the following ways to finish some site make tasks:

Display a form

<?php echo $html->formTag('/datas/function') ?>
<lable>Field1:</label>
<?php echo $html->inputTag('Data/field1', array('size' => '40')) ?>
<?php echo $html->tagErrorMsg('Data/field1', 'field1 is required') ?>
<lable>Field2:</label>
<?php echo $html->inputTag('Data/field2', array('size' => '255')) ?>
<?php echo $html->tagErrorMsg('Data/field2', 'field2 is invalid') ?>
<?php echo $html->submitTag('function') ?>
</form>


Data validation

var $validate = array (
'field1' => VALID_NOT_EMPTY,
'field2' => '/^.{6,40}$/',
'field3' => VALID_EMAIL
);


Save form data to database

if (!empty($this->data)) {
if ($this->Data->validates($this->data)) {
$this->Data->save($this->data);
$this->flash('Success messages');
} else {
$this->flash('Error messages');
}
}


Display a table

<table>
<?php
echo $html->tableHeaders(array_keys($datas[0]['Data']));
foreach ($datas as $data) {
echo $html->tableCells($data['Data'], array(’bgcolor’ => ‘#ddd’));
}
?>
</table>
