DataBase Schema File (.sql file ) Download with laravel - laravel

Schenario :
1) suppose that i have a database called myDataBase
2) Assume that myDataBase have some tables like A,B,C,D
3) i have to download the schema of the table A,B from the database with name myDataBase

Hope you have done the migration of all the table of your project . If you are using a xampp server then goto http://localhost/phpmyadmin and select your database and then goto export tab on the top tab bar and simply export with go button

Unique Case of "Call to a member function set_type() on null"

Hello guys i have gone through all 25 questions relating to the title of my question and i am made to believe my scenario is totally different.
Here is the error
Fatal error: Uncaught Error: Call to a member function set_type() on null in /path_to_file/login.php:55 Stack trace: #0 /path_to_call_page/login.php(24): login->authenticate() #1 {main} thrown in /path_to_file/login.php on line 55
Here is my code
<?php
class login
{
public $username;
public $password;
public $err;
public $table_name;
public $session_data;
public $md5 = true;
public $username_column = "username";
public $password_column = "password";
public $builder;
function _construct($username,$password)
{
$this->username = $username;
$this->password = $password;
$this->builder = new queryBuilder();
}
function set_table($tablename)
{
$this->table_name = $tablename;
}
/*

*/
function set_columns($username_col,$password_col)
{
$this->username_column = $username_col;
$this->password_column = $password_col;
}
function md5_on()
{

}

}

else
{

}
else
{
$this->err = "Invalid username or password. Please try again";

Any pointers would help. Remember i have been through previous questions so a suggested edit or code answer would be great.

Magento export categories -> import with magmi

we need to change the categories of some products and it is easier for us to do this with a csv file.
Is there a way to export the categories in magmi format?
sku,categories
"abc","cat1/cat2;;cat5/cat6/cat1"
"bgb","cat1/cat2"
or is there maybe a small tool to manage the products in categories?
Edit:
this is the current code which is displaying the category names.
But I am trying to display the category path like this:
FirstCat/Tools/Screwdriver
But it is displaying like this:
FirstCat/Screwdriver/Tools
so the categoryid is not sorted.

In this solution the db was'n in very well state, so the url needs to grabbed separately, you can remove that part if not necessary for you.
I used this on EE 1.13.0.2
You can run it from the shell.
Now here is my solution. Its displaying the csv in the browser. After that you can reimport with magmi
<?php
error_reporting(E_ALL | E_STRICT);
define('MAGENTO_ROOT', getcwd());
$mageFilename = MAGENTO_ROOT . '/app/Mage.php';
require_once $mageFilename;
Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);
Mage::app();
$products = Mage::getModel("catalog/product")->getCollection();
$products->addAttributeToSelect('category_ids');
$products->addAttributeToSelect('sku');
$products->addAttributeToFilter('status', 1);//optional for only enabled products
$products->addAttributeToFilter('visibility', 4);//optional for products only visible in catalog and search
foreach ($products as $product){
$sku = $product->getSku();
echo $sku.",";

I get the following results:
In my template file I echo the pagination:
<?php echo $this->pagination->getPagesLinks(); ?>
By the way, clicking on 'next' does change the url into ...?start=5.
This line in populateState is commented out
$this->setState('list.start', JRequest::getVar('limitstart', 0, '', 'int'));
Uncomment it change it tot get the "start" parameter:
$this->setState('list.start', JRequest::getVar('start', 0, '', 'int'));

How to write Some Data in CSV file in Magento?

I am trying print some shipment details as a CSV file and I am almost done in implementing this but it does not gives the the option for downloading.It automatically create the file and save it in the directory mentioned.
I think I am missing _prepareDownloadResponse() function but how do I implement this.
I am using this code ->
$file_path = 'sample_shipment.csv';
$mage_csv = new Varien_File_Csv();
$mage_csv->saveData($file_path, $content);
Edit:
All this code is in my indexcontroller.php
full code in indexcontroller.php ->
class Company_Manifestupload_IndexController extends Mage_Adminhtml_Controller_Action
{
public function indexAction() {
echo 'Manifestupload Index!';
}
public function bluedartmanifestuploadAction() {
$request = $this->getRequest();
$shipmentIds = $request->getPost('shipment_ids', array());
$file_path = 'manifest_upload_'.Mage::getSingleton('core/date')->date('d-m-Y_H-i-s').'_csv.csv';
$mage_csv = new Varien_File_Csv();
$shipment_csv=array();
/* Putting data in $shipment_csv[] */
$mage_csv->saveData($file_path, $shipment_csv);
}
In order to make the csv file downloadable, just put the following code inside the related controller action:
$fileName = 'filename.csv';
$content = $csvData; //prepare the csv data and return as string
$this->_prepareDownloadResponse($fileName, $content); //this will make the csv file downloadable with the $content as contents in it.
Hope this helps.
Edit:
Please find the updated controller action code.
public function bluedartmanifestuploadAction() {
$request = $this->getRequest();
$shipmentIds = $request->getPost('shipment_ids', array());
$fileName = 'manifest_upload_'.Mage::getSingleton('core/date')->date('d-m-Y_H-i-s').'_csv.csv';
//prepare csv contents
#prepare header
$csv = '';
$_columns = array(
"field1",
"field2",
//...
);
$data = array();
foreach ($_columns as $column) {
$data[] = '"'.$column.'"';
}
$csv .= implode(',', $data)."\n";
#prepare data
foreach($dataFromShipmentIds as $_data){ //just dummy loop
$data = array();
$data[] = $_data['field1'];
$data[] = $_data['field2'];
//...
$csv .= implode(',', $data)."\n";
}
//now $csv varaible has csv data as string
$this->_prepareDownloadResponse($fileName, $csv);
}
Edit 2: The above code will only work properly in ideal case.It will not generate proper Csv when there "\n"s and ","s in the fields .To make it work properly one can use code from varien file CSV .I'll add it here-
First make array of values in $data[] as above then instead of using $csv.=implode(',',$data)."\n" use the below code.
foreach ($data as $value) {
if (strpos($value, $delimiter) != false ||
strpos($value, $enclosure) != false ||
strpos($value, "\n") != false ||
strpos($value, "\r") != false ||
strpos($value, "\t") != false ||
strpos($value, ' ') != false) {
$str2 = $enclosure;
$escaped = 0;
$len = strlen($value);
for ($i=0;$i<$len;$i++) {
if ($value[$i] == $escape_char) {
$escaped = 1;
} else if (!$escaped && $value[$i] == $enclosure) {
$str2 .= $enclosure;
} else {
$escaped = 0;
}
$str2 .= $value[$i];
}
$str2 .= $enclosure;
$str .= $str2.$delimiter;
} else {
$str .= $enclosure.$value.$enclosure.$delimiter;
}
}
$str = substr($str,0,-1);
$str .= "\n";
If you want to create downloadable csv of you ordered item's you can use following script.
$orders = Mage::getModel("sales/order")->getCollection();
// prepare CSV header
$csv = '';
$_columns = array(
"Order Id",
"Product Name",
"Sku",
"Price"
);
$data = array();
// prepare CSV header...
foreach ($_columns as $column) {
$data[] = '"'.$column.'"';
}
$csv .= implode(',', $data)."\n";
foreach ($orders as $order) {
$items = $order->getAllItems();
foreach ($items as $item) {
$loadProduct = Mage::getModel('catalog/product')->load($item->getProductId());
//prepare csv contents
$data = array();
$data[] = $order->getId();
$data[] = $loadProduct['name'];
$data[] = $loadProduct['sku'];
$data[] = $loadProduct['price'];
$csv .= implode(',', $data)."\n";
//now $csv varaible has csv data as string
}
}
$this->_redirect('*/*/');
$this->_prepareDownloadResponse('file.csv', $csv, 'text/csv');

The problem that causes the red screen with 500 Error is happening because you are raising an exception if the requested quote is does not exist. You should not use JError::raiseError().
Use one of the following instead:
// This will set error to the model. You can get the errors from
// the model by your controller $model->getErrors() and output them to the screen.
$this->setError('ERROR MESSAGE GOES HERE');
OR
// This will output errors to the screen right the way
JFactory::getApplication()->enqueueMessage('ERROR MESSAGE GOES HERE', 'message');
Model already has _db property, you do not need to get db into variable. You can access it like this $this->_db. You can read about Joomla Model class here.
Also within your model you are using
$db = $this->getDBO();
$db->setQuery('SELECT * from #__todaysdeal');
$deals = $db->loadObjectList();
Model has simplified method to load list of object, like so
$deals =& $this->_getList('SELECT * from #__todaysdeal');
