Here is what i have in: /app/code/community/VivasIndustries/SmsNotification/Block/Adminhtml/Sales/Status/Grid.php:

<?php

class VivasIndustries_SmsNotification_Block_Adminhtml_Sales_Status_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
    public function __construct()
    {
        parent::__construct();
        $this->setId('smsnotification_grid');
        $this->setDefaultSort('id');
        $this->setDefaultDir('DESC');
        $this->setSaveParametersInSession(true);
        $this->setUseAjax(true);
    }


protected function _prepareCollection()
  {
      $collection = Mage::getResourceModel('smsnotification/smsnotification_collection');
      $this->setCollection($collection);
      return parent::_prepareCollection();
  }


protected function _prepareColumns()
  {
      $this->addColumn('id', array(
          'header'    => Mage::helper('smsnotification')->__('ID'),
          'align'     =>'right',
          'width'     => '50px',
          'index'     => 'id',
      ));

      $this->addColumn('Name', array(
          'header'    => Mage::helper('smsnotification')->__('Name'),
          'align'     =>'left',
          'index'     => 'Name',
      ));    

      return parent::_prepareColumns();
  }

        public function getGridUrl()
        {
            return $this->getUrl('*/*/grid', array('_current'=>true));
        }
    }

I have custom table named VivasIndustries_SmsNotification and here is the structure of that table:

enter image description here

I want this data to be displayed in the grid table, but i receive the following error so far:

Fatal error: Call to a member function getReadConnection() on a non-object in /public_html/store/app/code/core/Mage/Core/Model/Resource/Db/Collection/Abstract.php on line 134

Let me show what i have in some other files which i think can be important for this error.

I have in: /app/code/community/VivasIndustries/SmsNotification/Model/SmsNotification.php:

<?php
class VivasIndustries_SmsNotification_Model_Smsnotification extends extends Mage_Core_Model_Abstract
{
    public function _construct()
    {
        parent::_construct();
        $this->_init('smsnotification/smsnotification');
    }

}

Here is what i have in: /app/code/community/VivasIndustries/SmsNotification/Model/Resource/Smsnotification.php:

<?php
class VivasIndustries_SmsNotification_Model_Resource_Smsnotification extends Mage_Core_Model_Resource_Db_Abstract
{
    /**
     * Initialize resource model
     *
     * @return void
     */
    public function _construct()
    {
        $this->_init('smsnotification/smsnotification','id');
    }
}

Here is what i have in: /app/code/community/VivasIndustries/SmsNotification/Model/Resource/Smsnotification/Collection.php:

<?php 
class VivasIndustries_SmsNotification_Model_Resource_Smsnotification_Collection extends Mage_Core_Model_Resource_Db_Collection_Abstract{
    protected function _constuct(){
        $this->_init('smsnotification/smsnotification');    
    }
}

Can you please help me out resolve this error?
I simply want to display the data from VivasIndustries_SmsNotification in a grid table in a page created by me in the Admin panel.

Thanks in advance!

Your problem is probably here:

I have in:     /app/code/community/VivasIndustries/SmsNotification/Model/SmsNotification.php:

<?php
class VivasIndustries_SmsNotification_Model_Smsnotification extends extends     Mage_Core_Model_Abstract

You have a case error and a typo. You have two "extends" and based on your directory structure your class should read:

class VivasIndustries_SmsNotification_Model_SmsNotification extends     Mage_Core_Model_Abstract

Magento – How to get data from custom MySQL table into your Adminhtml grid table

The lex.you need to create a model using a custom module.

Step: You have define model class and resource type but not define resource Class

<models>
        <smsnotification>
            <class>VivasIndustries_SmsNotification_Model</class> <!-- model prefix class -->
            <resourceModel>vivasindustries_smsnotification_resource</resourceModel>
<!-- model resource type -->

        </smsnotification>
    </models>

So you need to add resource class which is interact the model with database.

  <models>
......
    <vivasindustries_smsnotification_resource>
        <class>VivasIndustries_SmsNotification_Model_Resource</class>
        <entities>
            <custommodule>
            <table>VivasIndustries_SmsNotification</table> <!-- VivasIndustries_SmsNotification is Your db tabale -->
            </custommodule>
        </entities>
        </vivasindustries_smsnotification_resource>
</models>

VivasIndustries_SmsNotification_Model_Resource VivasIndustries_SmsNotification

you need to define class VivasIndustries_SmsNotification_Model_Smsnotification

code is

<?php
class VivasIndustries_SmsNotification_Model_Smsnotification extends extends Mage_Core_Model_Abstract
{
    public function _construct()
    {
        $this->_init('smsnotification/smsnotification');
    }

}

Resource class model class:

<?php
class VivasIndustries_SmsNotification_Model_Resource_Smsnotification extends Mage_Core_Model_Resource_Db_Abstract
{
    /**
     * Initialize resource model
     *
     * @return void
     */
    public function _construct()
    {
        $this->_init('smsnotification/smsnotification','id');
    }
}

Resource Collection model

<?php 
class VivasIndustries_SmsNotification_Model_Resource_Smsnotification_Collection 
extends Mage_Core_Model_Resource_Db_Collection_Abstract{
    protected function _constuct(){
        $this->_init('smsnotification/smsnotification');    
    }
}

[Please study at how create model][1]

Now you get a collection mode.

Now on preapareCollection

you need change code:

$collection =Mage::getResourceModel('smsnotification/smsnotification_collection);

You grid code is:

<?php

class VivasIndustries_SmsNotification_Block_Adminhtml_Smsnotification_Grid extends Mage_Adminhtml_Block_Widget_Grid
{

        public function __construct()
        {
                parent::__construct();
                $this->setId("smsnotificationGrid");
                $this->setDefaultSort("id");
                $this->setDefaultDir("DESC");
                $this->setSaveParametersInSession(true);
        }

        protected function _prepareCollection()
        {
                $collection = Mage::getModel("smsnotification/smsnotification")->getCollection();
                $this->setCollection($collection);
                return parent::_prepareCollection();
        }
        protected function _prepareColumns()
        {
                $this->addColumn("id", array(
                "header" => Mage::helper("smsnotification")->__("ID"),
                "align" =>"right",
                "width" => "50px",
                "type" => "number",
                "index" => "id",
                ));

                $this->addColumn("receiver", array(
                "header" => Mage::helper("smsnotification")->__("Receiver"),
                "index" => "receiver",
                ));
                $this->addColumn("phone", array(
                "header" => Mage::helper("smsnotification")->__("Phome"),
                "index" => "phone",
                ));
                    $this->addColumn('date', array(
                        'header'    => Mage::helper('smsnotification')->__('Data'),
                        'index'     => 'date',
                        'type'      => 'datetime',
                    ));
            $this->addExportType('*/*/exportCsv', Mage::helper('sales')->__('CSV')); 
            $this->addExportType('*/*/exportExcel', Mage::helper('sales')->__('Excel'));

                return parent::_prepareColumns();
        }

        public function getRowUrl($row)
        {
               return $this->getUrl("*/*/edit", array("id" => $row->getId()));
        }



        protected function _prepareMassaction()
        {
            $this->setMassactionIdField('id');
            $this->getMassactionBlock()->setFormFieldName('ids');
            $this->getMassactionBlock()->setUseSelectAll(true);
            $this->getMassactionBlock()->addItem('remove_smsnotification', array(
                     'label'=> Mage::helper('smsnotification')->__('Remove Smsnotification'),
                     'url'  => $this->getUrl('*/adminhtml_smsnotification/massRemove'),
                     'confirm' => Mage::helper('smsnotification')->__('Are you sure?')
                ));
            return $this;
        }


}

Update code at config.xml

<global>
...
<models>
        <smsnotification>
            <class>VivasIndustries_SmsNotification_Model</class> <!-- model prefix class -->

Adminhtml – How to Create New Admin Form in Magento 1.9

Sounds like you need a form and a form container. It's similar to what you already did with the grid.

You must create these files:

/app/code/community/VivasIndustries/SmsNotification/Block/Adminhtml/Sms/Status/Edit.php

class VivasIndustries_SmsNotification_Block_Adminhtml_Sms_Status_Edit 
     extends Mage_Adminhtml_Block_Widget_Form_Container

/app/code/community/VivasIndustries/SmsNotification/Block/Adminhtml/Sms/Status/Edit/Form.php

class VivasIndustries_SmsNotification_Block_Adminhtml_Sms_Status_Edit_Form 
     extends Mage_Adminhtml_Block_Widget_Form

Checkout the Form Container Block section in this article (It's a really good one). You should render these blocks in the appropiate action in the controller, and add an extra action to handle the form submission. This second action receives the data via POST, passes it to the model and saves it to the database.
