How add create AdditionalActionBlockHtml into massactions in category products grid?
like this status
I founded getAdditionalActionBlockHtml in app/design/adminhtml/default/default/template/widget/grid/massaction.phtml
But I'm dont understand how it's work.
<div class="right">
<div class="entry-edit">
<?php if ($this->getHideFormElement() !== true):?>
<form action="" id="<?php echo $this->getHtmlId() ?>-form" method="post">
<?php endif ?>
<?php echo $this->getBlockHtml('formkey')?>
<fieldset>
<span class="field-row">
<label><?php echo $this->__('Actions') ?></label>
<select id="<?php echo $this->getHtmlId() ?>-select" class="required-entry select absolute-advice local-validation">
<option value=""></option>
<?php foreach($this->getItems() as $_item): ?>
<option value="<?php echo $_item->getId() ?>"<?php echo ($_item->getSelected() ? ' selected="selected"' : '')?>><?php echo $_item->getLabel() ?></option>
<?php endforeach; ?>
</select>
</span>
<span class="outer-span" id="<?php echo $this->getHtmlId() ?>-form-hiddens"></span>
<span class="outer-span" id="<?php echo $this->getHtmlId() ?>-form-additional"></span>
<span class="field-row">
<?php echo $this->getApplyButtonHtml() ?>
</span>
</fieldset>
<?php if ($this->getHideFormElement() !== true):?>
</form>
<?php endif ?>
</div>
<div class="no-display">
<?php foreach($this->getItems() as $_item): ?>
<div id="<?php echo $this->getHtmlId() ?>-item-<?php echo $_item->getId() ?>-block">
<?php echo $_item->getAdditionalActionBlockHtml() ?>
</div>
<?php endforeach; ?>
</div>
</div>
I decided this via add methods in massactions
public function addMassAction($observer)
{
$block = $observer->getEvent()->getBlock();
if(get_class($block) =='Mage_Adminhtml_Block_Widget_Grid_Massaction' && $block->getRequest()->getControllerName() == 'catalog_product')
{
$stores = Mage::getSingleton('adminhtml/system_config_source_store')->toOptionArray();
$block->addItem('export', array(
'label' => Mage::helper("prodestransl")->__("Export"),
'url' => Mage::helper('adminhtml')->getUrl('prod/adminhtml_export/run'),
'additional' => array(
'stores' => array(
'name' => 'stores',
'type' => 'select',
'class' => 'required-entry',
'label' => Mage::helper('catalog')->__('Stores'),
'values' => $stores
)
)
));
}
}

I'm trying to set validation error to the my form using flashdata in codeigniter but i cannot see the error in a view here is my code of view section. I had already read other relative questions close to my this problem but i'm not found a solution!
<?php if($this->session->flashdata('errors')): ?>
<?php echo $this->session->flashdata('errors');?>
<?php endif; ?>
<?php $attributes = array('id'=>'admin_login','class'=>'form-horizontal'); ?>
<?php echo form_open('admin/login', $attributes); ?>
<div class="form-group">
<?php
$lbl = array('class'=>'col-sm-12 col-lg-12 col-md-12 col-xs-12 control-label');
echo form_label('Email','admin_login',$lbl); ?>
<div class="col-sm-12 col-lg-12 col-md-12 col-xs-12">
<?php $data = array('
class'=> 'form-control col-sm-12 col-lg-12 col-md-12 col-xs-12',
'name'=> 'email',
'placeholder'=>'Enter your email'
); ?>
<?php echo form_input($data); ?>
</div>
</div>
<div class="form-group">
<?php
echo form_label('Password','admin_login',$lbl); ?>
<div class="col-sm-12 col-lg-12 col-md-12 col-xs-12">
<?php $data = array('
class'=> 'form-control',
'name'=> 'password',
'placeholder'=>'Password'
); ?>
<?php echo form_password($data); ?>
</div>
</div>
<div class="form-group">
<div class="col-sm-12 col-lg-12 col-md-12 col-xs-12">
<?php $data = array('
class'=> 'btn btn-success btn-md center mt-2',
'name'=> 'submit',
'placeholder'=>'Password',
'value'=>'LOGIN',
'type'=>'submit'
); ?>
<center>
<?php echo form_submit($data); ?>
</center>
</div>
</div>
<?php echo form_close(); ?>
This is my controller part it is name of 'admin' method name is login
public function login(){
$this->form_validation->set_rules('email','Email','required');
$this->form_validation->set_rules('password','Password','required');
// check the form has any error (any miss of rules we set in above codes
if($this->form_validation->run() == FALSE){
$this->session->set_flashdata('errors',
validation_errors());
// $this->session->set_flashdata('name','Your message');
// $errors = validation_errors();
// $this->session->set_flashdata('form_error', $errors);
// $this->session->set_flashdata('name','Your message');
// $data = array('errors'=> validation_errors());
// set_userdata() is regular way to set session, it need manually unset, there for we use flashdata
// $this->session->set_flashdata($data);
}else{
echo "its all good";
}
}
i tried so many codes, i commented out what i used so far. I set in autoload section session library also $autoload['libraries'] = array('database','form_validation','session');
Please tell me what is the wrong here.
Please try with the below code.
public function login(){
$this->form_validation->set_rules('email','Email','required');
$this->form_validation->set_rules('password','Password','required');
if($this->form_validation->run() == true){
echo "its all good";
}else{
$this->session->set_flashdata('errors', validation_errors());
}
$this->load->view('Your View Page');
}
I a working on a dependent dropdown in yii, I want the department dropdown to autoload with the departments depending on what faculty I select, the course dropdown to load with courses once i select a department, the code almost works except that the dropdowns are updating themselves rather than the dropdowns beneath. How can I make them update properly?
this is the
views/site/newuser:
`<div class="row">`
<?php echo $form->labelEx($model,'faculty_id'); ?>
<?php echo $form->dropDownList($model,'faculty_id',
CHtml::listData(Faculty::model()->findAll(),'id','faculty_name'),
array(
'prompt'=>'Select Faculty',
'ajax' => array(
'type'=>'POST',
'url'=>Yii::app()->createUrl('site/loaddepartment'),
'update'=>'#NewUser_faculty_id',
'data'=>array('faculty_id'=>'js:this.value'),)));
?>
<?php echo $form->error($model,'faculty_id'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'department_id'); ?>
<?php echo $form->dropDownList($model,'department_id',
CHtml::listData(Department::model()->findAll(),'id','department_name'),
array(
'prompt'=>'Select Department',
'ajax' => array(
'type'=>'POST',
'url'=>Yii::app()->createUrl('site/loadcourses'),
'update'=>'#NewUser_department_id',
'data'=>array('department_id'=>'js:this.value'),)));
?>
<?php echo $form->error($model,'department_id'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'course_id'); ?>
<?php echo CHtml::dropDownList('department_name','', array(), array(
'prompt'=>'Select Course'
)); ?>
<?php echo $form->error($model,'course_id'); ?>
</div>
<div class="row buttons">
<?php echo CHtml::submitButton('Submit'); ?>
</div>
<?php $this->endWidget(); ?>
this is in the controller:
public function actionloaddepartment()
{
$data=Department::model()->findAll('faculty_id=:faculty_id',
array(':faculty_id'=>(int) $_POST['faculty_id']));
$data=CHtml::listData($data,'id','department_name');
echo "<option value=''>Select Department</option>";
foreach($data as $value=>$department_name)
echo CHtml::tag('option', array('value'=>$value),CHtml::encode($department_name),true);
}
public function actionloadcourses()
{
$data=Courses::model()->findAll('department_id=:department_id',
array(':department_id'=>(int) $_POST['department_id']));
$data=CHtml::listData($data,'id','course_name');
echo "<option value=''>Select course</option>";
foreach($data as $value=>$course_name)
echo CHtml::tag('option', array('value'=>$value),CHtml::encode($course_name),true);
}
so, I was able to get a fix, Thank God, here it is, so incase any one might need it
this is the new/views/site/newuser:
<?php echo $form->errorSummary($model); ?>
<div class="row">
<?php echo $form->labelEx($model,'first_name'); ?>
<?php echo $form->textField($model,'first_name'); ?>
<?php echo $form->error($model,'first_name'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'last_name'); ?>
<?php echo $form->textField($model,'last_name'); ?>
<?php echo $form->error($model,'last_name'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'email'); ?>
<?php echo $form->textField($model,'email'); ?>
<?php echo $form->error($model,'email'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'faculty_id'); ?>
<?php echo $form->dropDownList($model,'faculty_id',
CHtml::listData(Faculty::model()->findAll(),'id','faculty_name'),
array(

'ajax' => array(
'type'=>'POST',
'url'=>Yii::app()->createUrl('site/loaddepartment'),

'data'=>array('faculty_id'=>'js:this.value'
),
)));
?>
<?php echo $form->error($model,'faculty_id'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'department_id'); ?>
<?php echo CHtml::dropDownList('department_id','', array(),
array(
'ajax' => array(
'type'=>'POST',
'url'=>Yii::app()->createUrl('site/loadcourses'),
'update'=>'#course_id',
'data'=>array('department_id'=>'js:this.value'
),
)))
?>
<?php echo $form->error($model,'department_id'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'course_id'); ?>
<?php echo CHtml::dropDownList('course_id','', array()
)?>
<?php echo $form->error($model,'course_id'); ?>
</div>
<div class="row buttons">
<?php echo CHtml::submitButton('Submit'); ?>
</div>
This is the New controller:
public function actionloaddepartment()
{
$data=Department::model()->findAll('faculty_id=:faculty_id',
array(':faculty_id'=>(int) $_POST['faculty_id']));
$data=CHtml::listData($data,'id','department_name');
foreach($data as $value=>$department_name)
echo CHtml::tag('option', array('value'=>$value),CHtml::encode($department_name),true);
}
public function actionloadcourses()
{
$data=Courses::model()->findAll('department_id=:department_id',
array(':department_id'=>(int) $_POST['department_id']));
$data=CHtml::listData($data,'id','course_name');
foreach($data as $value=>$course_name)
echo CHtml::tag('option', array('value'=>$value),CHtml::encode($course_name),true);
}
I copied estimatePostAction and made estimateAjaxPostAction (overriding core - I did not hack the core). The controller action works as well (class Mage_Checkout_CartController).
Now I want to get/create a block for replacing shipping block after estimate shipping with ajax. I tried this:
public function estimateAjaxPostAction()
{
$country = (string) $this->getRequest()->getParam('country_id');
$postcode = (string) $this->getRequest()->getParam('estimate_postcode');
$city = (string) $this->getRequest()->getParam('estimate_city');
$regionId = (string) $this->getRequest()->getParam('region_id');
$region = (string) $this->getRequest()->getParam('region');
$this->_getQuote()->getShippingAddress()
->setCountryId($country)
->setCity($city)
->setPostcode($postcode)
->setRegionId($regionId)
->setRegion($region)
->setCollectShippingRates(true);
$this->_getQuote()->save();
//$this->_goBack();
$this->loadLayout();
$block = $this->getLayout()->createBlock('Mage_Checkout_Block_Cart_Shipping','checkout.cart.shipping.ajax',array('template' => 'checkout/cart/shipping.phtml'));
if($block) {
$response = array();
$response['shipping'] = $block->toHtml();
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
}
}
The block checkout.cart.shipping.ajax was created. But toHtml() returns nothing.
My JSON returns:
{"shipping":""}
Why toHtml method doesn't work?
Edit: My block code (checkout/cart/shipping.phtml)
<?php /** #var $this Mage_Checkout_Block_Cart_Shipping */ ?>
<div class="row contem-shipping">
<div class="col-xs-10 shipping">

Denis... I have modify code please check
public function estimateAjaxPostAction()
{
$country = (string) $this->getRequest()->getParam('country_id');
$postcode = (string) $this->getRequest()->getParam('estimate_postcode');
$city = (string) $this->getRequest()->getParam('estimate_city');
$regionId = (string) $this->getRequest()->getParam('region_id');
$region = (string) $this->getRequest()->getParam('region');
$this->_getQuote()->getShippingAddress()
->setCountryId($country)
->setCity($city)
->setPostcode($postcode)
->setRegionId($regionId)
->setRegion($region)
->setCollectShippingRates(true);
$this->_getQuote()->save();
$response = array();
$response['shipping']=$this->eastmatesajax();
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
}
protected function eastmatesajax()
{
$layout=$this->getLayout();
$layout->getMessagesBlock()->setMessages(Mage::getSingleton('checkout/session')->getMessages(true),Mage::getSingleton('catalog/session')->getMessages(true));
$block = $this->getLayout()->createBlock('checkout/cart_shipping')->setTemplate( 'checkout/cart/shipping.phtml');
return $block->toHtml();
}
Updated block issue solved using $this->_getQuote()->collectTotals(); before $this->_getQuote()->save();
I have a problem with Magento currency: My code is working fine otherwise, now I want to redirect the page after a change of currency.
Suppose my current URL is http://www.example.com/women/?color=black.
Now, When I change currency it will redirect to: http://www.example.com/women/; so it removes ?color=black.
Code:
if($this->getCurrencyCount()>1): ?>
<div class="block block-currency">
<div class="block-title">
<strong><span><?php echo $this->__('Select Your Currency') ?></span></strong>
</div>
<div class="block-content">
<select name="currency" title="<?php echo $this->__('Select Your Currency') ?>" onchange="setLocation(this.value)">
<?php foreach ($this->getCurrencies() as $_code => $_name): ?>
<option value="<?php echo $this->getSwitchCurrencyUrl($_code) ?>"<?php if($_code==$this->getCurrentCurrencyCode()): ?> selected="selected"<?php endif; ?>>
<?php echo $_name ?> - <?php echo $_code ?>
</option>
<?php endforeach; ?>
</select>
</div>
</div>
<?php endif;
Updated Code:
<?PHP $currentParams = $this->getRequest()->getParams(); ?>
<div style="float:left; margin-top:10px; color:#727478;">
<!--Change 1 to 0 if you wish to output selector always-->
<?php if($this->getCurrencyCount() > 1): ?>
<span>Select Currency:</span>
<select name="custom-currency-selector" id="custom-currency-selector">
<?php foreach ($this->getCurrencies() as $_code => $_name):
$currencyUrl = $this->getSwitchCurrencyUrl($_code);
foreach ($currentParams as $_param) {
$currencyUrl = $this->helper('core/url')->addRequestParam($currencyUrl, $_param);
}
?>
<option value="<?php echo $currencyUrl; ?>"
<?php if($_code == $this->getCurrentCurrencyCode()): ?>
selected="SELECTED"
<?php endif; ?>>
<?php echo $_code ?>
</option>
<?php endforeach; ?>
</select>
<?php endif;?>
Updated Code:
<!--Change 1 to 0 if you wish to output selector always-->
<?php if($this->getCurrencyCount() > 1):
$currentParams = $this->getRequest()->getParams();
?>
<span>Select Currency:</span>
<select name="custom-currency-selector" id="custom-currency-selector">
<?php foreach ($this->getCurrencies() as $_code => $_name):
$currencyUrl = $this->helper('core/url')->addRequestParam($this->getSwitchCurrencyUrl($_code),$currentParams)
?>
<option value="<?php echo $currencyUrl ?>"
<?php if($_code == $this->getCurrentCurrencyCode()): ?>
selected="SELECTED"
<?php endif; ?>>
<?php echo $_code ?>
</option>
<?php endforeach; ?>
</select>
<?php endif; ?>
You should add these params to the new url:
$currentParams = $this->getRequest()->getParams();
$currencyUrl = $this->helper('core/url')->addRequestParam(
$this->getSwitchCurrencyUrl($_code),
$currentParams
)
Then use $currencyUrl as url for redirect.

There's a problem with your form_submit.
form_submit has 2 parameters, which accept name and value of the input.
echo form_submit('oksubmit', 'Submit!');
which will produce:
<input type="submit" name="oksubmit" value="Submit!" />
