I want to populate the form using the above data from tha database table. But I don't know how to this. Please help me. Thanks

Answer 1

You can overwrite the populate function in your form.
public function populate($data)
{
foreach($data as $field => $value)
{
$this->{$field}->setValue($value);
}
return $this;
}
where $data is an associated array of name => value.
[edit]
So you form is now:
<?php
class Form_Admin_Settings_Add extends Zend_Form
{
public function init()
{
$houserent = new Zend_Form_Element_Text('houserent');
$houserent->setLabel('House Rent :');
$this->addElement($houserent);
$tax = new Zend_Form_Element_Text('tax');
$siteName->setLabel('Tax :');
$this->addElement($tax);
$internet = new Zend_Form_Element_Text('internet');
$internet->setLabel('Internet :');
$this->addElement($internet);
}
public function populate($data)
{
foreach($data as $field => $value)
{
$this->{$field}->setValue($value);
}
return $this;
}
}
In your controller:
<?php
//instantiate form and model
$form = new Form_Admin_Settings_Add();
$model = new Model_Test();
//get results
$results = $model->fetchAll()->toArray();
$data = array();
//put results into our data array as name => value
foreach($results as $r)
{
$data[$r['name']] = $r['value'];
}
//populate our form
$form->populate(data);
echo $form;

Try some like this:
class Form extends Zend_Form {
public funcition Form(){
$houserent = new Zend_Form_Element_Text('houserent');
$houserent->setLabel('House Rent :')
->setValue($this->_Data['houserent']);
$this->addElement($houserent);
}
public function setData($Data){
$this->_Data = $Data;
return $this;
}
}
