Magento Change Pager Phtml Custom Module

In you block of custom module, for e.g.In my case,  Netgo_Userstatus_Block_Userstatus_List

Just Use the blow code in _prepareLayout() function

  protected function _prepareLayout()
{
        parent::_prepareLayout();
        $pager = $this->getLayout()->createBlock(
            'page/html_pager',
            'netgo_userstatus.userstatus.html.pager'
        )->setTemplate('page/html/newsfeed_pager.phtml')
        ->setCollection($this->getUserstatuss());
        $this->setChild('pager', $pager);
        $this->getUserstatuss()->load();
        return $this;
    }

The Red colored is the extra code that I have added, you can define your phtml file for the pager.

Magento admin change default page size of grid

You have to modify two files for that: Grid.php and Grid.phtml,
Below are the details of files:

In Admin Block File:
/public_html/app/code/core/Mage/Adminhtml/Block/Widget
Grid.php

Search for $_defaultLimit in the file and change the value according to your choice.
protected $_defaultLimit    = 75;

PHTML File:
app/design/adminhtml/default/default/template/widget
grid.phtml

Add your option in the select box.

<select name="<?php echo $this->getVarNameLimit() ?>" onchange="<?php echo $this->getJsObjectName() ?>.loadByElement(this)">
<option value="20"<?php if($this->getCollection()->getPageSize()==20): ?> selected="selected"<?php endif; ?>>20</option>
<option value="30"<?php if($this->getCollection()->getPageSize()==30): ?> selected="selected"<?php endif; ?>>30</option>
<option value="50"<?php if($this->getCollection()->getPageSize()==50): ?> selected="selected"<?php endif; ?>>50</option>
<option value="75"<?php if($this->getCollection()->getPageSize()==75): ?> selected="selected"<?php endif; ?>>75</option>
<option value="100"<?php if($this->getCollection()->getPageSize()==100): ?> selected="selected"<?php endif; ?>>100</option>
<option value="200"<?php if($this->getCollection()->getPageSize()==200): ?> selected="selected"<?php endif; ?>>200</option>
</select>

I have added 75 as additional page size, It will be default pagesize too.

Facebook page feed time issue

I was implementing facebook page feed for one of my client, the feeds were appearing correct but time was different, actually it was a timezone issue, you have to convert facebook time to local timezone, and to do this i found the perfect way.

step1.
Download and include the js file into your script.

https://gist.github.com/aredo/4153245

step2:

use below code to determine the client timezone:

<script type="text/javascript">
    jQuery(document).ready(function() {
       var timezone = jstz.determine();
var timezonename = timezone.name();  
    });
</script>

<?php echo $catlistHtml; ?>  
</select>
<?php

    for ($x=0;$x<$n;$x++){ $str = $char . $str; }
    return $str;
}
function getTreeCategories($parentId, $isChild){
    $_cathelper = Mage::helper('catalog/category');
$allCats = Mage::getModel('catalog/category')->getCollection()
                ->addAttributeToSelect('*')
                ->addAttributeToFilter('is_active','1')
                ->addAttributeToFilter('parent_id',array('eq' => $parentId));
    $class = ($isChild) ? "sub-cat-list" : "cat-list";
    //$children = Mage::getModel('catalog/category')->getCategories(7);
    foreach ($allCats as $category)
    {
   $prefix = '';
   $_category =  Mage::getModel('catalog/category')->load($category->getId());
   $lblval=$_category->getLevel()-3;
$catname = ($lblval==0)?strtoupper($_category->getName()):$_category->getName();
$catname =  str_prefix($catname,$lblval*2,"-");
        $html .= '<option lbl="'.$_category->getLevel().'" value="'.$_category->getId().'" caturl="'.$_cathelper->getCategoryUrl($_category).'" >'.$catname."</option>";
        $subcats = $category->getChildren();
        if($subcats != ''){
            $html .= getTreeCategories($category->getId(), true);
        }
    }
    return $html;
}
$catlistHtml = getTreeCategories(6, false);

3.call that block in the phtml file where u want to implement datepicker.

<?php echo $this->getChildHtml('html_calendar') ?>

4. Last use the below code:

<script type="text/javascript">
  Calendar.setup({

magento display multi select attribute in admin grid with filter

I have created a custom module by name supplier , and displayed several supplier on the product page in admin like in the image above, Now the multiselected values were not appearing properly in the grid page.

It was appearing empty for multiselected values. although i managed to display single selected values properly by the post:

http://blog.chapagain.com.np/magento-how-to-search-or-filter-by-multiselect-attribute-in-admin-grid/

But still there was problem with multi selected values, so i defined "renderer"
$this->addColumn('supplier', array(
            'header'    => Mage::helper('catalog')->__('supplier'),
            'width'     => '180px',
            'index'     => 'supplier',
            'type'  => 'options',
            'options' => $item_types,
             'filter_condition_callback' => array($this, '_filterSupplierCallback'),
            'renderer'=>new Mage_Adminhtml_Block_Catalog_Product_Columns_Supplier()        ));

IN THE RENDERER I USED BELOW CODE TO RETURN THE LIST OF MULTI SELECTED SUPPLIER:

public function render(Varien_Object $row)
    {
        $suppliers=explode(',',$row->getSupplier());
        $suppstr="";
        if(count($suppliers)>0)
        {
            $suppstr="<ul>";
            foreach($suppliers as $value)
            {
                $productModel = Mage::getModel('catalog/product');
                $attr = $productModel->getResource()->getAttribute("supplier");
                if ($attr->usesSource()) {
                $suppstr   .= "<li>".$attr->getSource()->getOptionText("$value")."</li>";
                }

            }
            $suppstr   .= "</ul>";
  
        }
          return $suppstr;   
       
    }



And successfully displayed multiselected options in the grid.

magento add custom validation to admin section field

well... i had to create my own custom validation class for my magento extension because the client said that.
'For Video title- it should accept alphabets[A-Za-z], numerics and also special charater "Space" , and also it should not start with number'.
since changing core file is a bad habit , so i created  my own js file and add my custom validation class.But first let me tell u how u can do it fast by modifying core file.
//BAD BUT FAST WAY...
open  js/prototype/validation.js

some where at line 479-771, u will see lots of validation classess that magento uses. U can define your own validation class like i did.

I added below code after line 489.

  ['validate-alphanum-with-spaces-char-first', 'Please use only letters (a-z or A-Z), numbers (0-9) or spaces only in this field, first character should be a letter.', function(v) {
                return Validation.get('IsEmpty').test(v) ||  /^[a-z]+[a-z0-9 ]+$/.test(v)
            }],

 //NOW THE STANDARD WAY....
1. add your custom js file to the module.
     in my case it was video edit section in admin:

 app/design/adminhtml/default/default/layout/mymod_video.xml
<layout>
<adminhtml_video_video_edit>
     <reference name="head">
                    <action method="addJs"><script>alfasoft/videoext/myvalidation.js</script></action>
        </reference>
        <reference name="content">
          ....
        </reference>
        <reference name="left">
          ....
        </reference>
    </adminhtml_video_video_edit>
</layout>

2. upload your js i.e. myvalidation.js to the location js/alfasoft/videoext/

3. Add your code to myvalidation.js
   if(Validation)
    {
        Validation.addAllThese([
           
            ['validate-alphanum-with-spaces-char-first', 'Please use only letters (a-z or A-Z), numbers (0-9) or spaces only in this field, first character should be a letter.', function(v) {
                return Validation.get('IsEmpty').test(v) ||  /^[a-z]+[a-z0-9 ]+$/.test(v)
            }]     // this is my validation requirement, your could be anything else.

        ]);
    }

Now Let me explain the code. according to my requirement.

>the regular expression fit the best /^[a-z]+[a-z0-9 ]+$/.test(v) . your could be anything else.
>here my validation class name is  'validate-alphanum-with-spaces-char-first'. 
>And my error message is:
'Please use only letters (a-z or A-Z), numbers (0-9) or spaces only in this field, first character should be a letter.'

 Use your class in the form:
mine path was:
app/code/community/Alfasft/Video/Block/Adminhtml/Video/Edit/Tab/Form.php

$fieldset->addField('vtitle', 'text', array(
            'label' => Mage::helper('video')->__('Video Title'),
            'name'  => 'vtitle',
            'required'  => true,
            'class' => 'required-entry validate-alphanum-with-spaces-char-first',

        ));

 //I have assign this class to the field 'vtitle'.

magento validation alpha numeric with spaces

Magento has a class , use this for  this validation

validate-alphanum-with-spaces

magento admin redirect to same url after post

 Put the below code at the end of the action:

$this->_redirectReferer($this->getRequest()->getServer('HTTP_REFERER'));
        return;

GET QUOTE ITEMS PRODUCT COUNT BY ATTRIBUTE

This code is for counting the total number to products in the cart having specific attribute code.

$items =Mage::getModel('checkout/cart')->getQuote()->getAllItems();
  $attriubtecnt=0;
 
   foreach($items as $item)
    {
$_product = Mage::getModel('catalog/product')->load($item->getProductId());
$att_value= $_product->getAttributeText('attributecode');

if(trim($att_value)=='lining')
{
                      $liningcnt +=$item->getTotalQty();
                 }

}
