The load function receives an array, which keys then parses as variables in the view. Thus, you get variables like $name, $password etc.
Just add another layer before calling the load function like:
$data['attributes'] = $attributes;
And then, when loading the view do
$this->load->view('login',$data);
Here is the array a bit adjusted:
$attributes = array(
'name' =>
array(
'name' => 'name',
'type' => 'text',
'placeholder' => '' ,
'value' => 'value'
),
'password' =>
array(
'name' => 'name',
'type' => 'password',
'placeholder' => '',
),
'gender' =>
array(
'name' => 'name',
'type' => 'select',
'options' => array(
'male' => 'Male',
'female' => 'Female'
),
),
'usertpye'=>array(
'type' => 'radio',
'values' => array(
'seller' => 'seller',
'buyer' => 'buyer'
)
),
'upload'=>array(
'type' => 'file',
'name' => 'file'
),
'submit'=>array(
'type' => 'submit',
'name' => 'submit',
'value' => 'submit'
)
);
Here is how it would look like with the form helper of CI (this would go in the view, remember to first load the helper in the controller):
echo form_open('email/send');
foreach($attributes as $key=>$attribute) {
echo form_label($key).'<br/>';
if($attribute['type'] == 'select') {
echo form_dropdown($attribute['name'],$attribute['options']).'<br/>';
} elseif($attribute['type'] == 'radio') {
foreach ($attribute['values'] as $value) {
echo form_label($value);
echo form_radio(array('name' => $key, 'value' => $value)).'<br/>';
}
} else {
echo form_input($attribute).'<br/>';
}
}
Note I did some adjustments to your initial attributes array to make it work, but you'd still need to improve its structure, add unique names for all items etc.
