I am using model below in CodeIgniter to get the sum of a column:
public function b2c_totalsales()
{
$this->db->select_sum('total_price');
$result=$this->db->from('orders_b2c');
return $result;
}
and in the controller:
$data['total_sales']=$this->reports_b2c->b2c_totalsales();
and I am getting:
Severity: 4096
Message: Object of class CI_DB_mysqli_driver could not be converted to string
Filename: views/reports_b2c.php
where is the error?
You need to execute the query with get:
$this->db->select_sum('total_price');
$result = $this->db->get('orders_b2c')->row();
return $result;

I am using Symfony 3.3.10
I have the following code
/**
* #Route("/meta/edit/{metaId}", name="edit_price_meta_data")
*/
public function editMetaAction(Request $request,ItemPriceMeta $metaId)
{
$metaDataForm = $this->createForm("ItemBundle\Form\ItemPriceMetaType");
$data = [
'metaData'=>$metaId,
'metaDataForm'=>$metaDataForm->createView(),
];
return $this->render("#Item/Prices/Manage/editMetaData.html.twig",$data);
}
It produces the following error.
Error: Maximum execution time of 60 seconds exceeded
in vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php (line 2513)
public function createEntity($className, array $data, &$hints = array()){
$class = $this->em->getClassMetadata($className);
//$isReadOnly = isset($hints[Query::HINT_READ_ONLY])
$id = $this->identifierFlattener->flattenIdentifier($class, $data);
$idHash = implode(' ', $id);
if (isset($this->identityMap[$class->rootEntityName][$idHash])) {
$entity = $this->identityMap[$class->rootEntityName][$idHash];
$oid = spl_object_hash($entity);
The actual line highlighted as causing the error is $id = $this->identifierFlattener->flattenIdentifier($class, $data);
Removing 'metaDataForm'=>$metaDataForm->createView(), from my array, removes the error, so it seems to be the rendering of the form that is causing the error.

When i am doing pagination using zend:
I am getting this error:
Notice: Undefined variable: db in /var/www/ZendApp/application/controllers/ContsizesController.php on line 17
Fatal error: Call to a member function fetchAll() on a non-object in /var/www/ZendApp/application/controllers/ContsizesController.php on line 17
//Controller
$sql = 'SELECT * FROM contsize ';
$result = $db->fetchAll($sql);
$page=$this->_getParam('page',1);
$paginator = Zend_Paginator::factory($result);
$paginator->setItemCountPerPage(10);
$paginator->setCurrentPageNumber($page);
$this->view->paginator=$paginator;
The above mentioned code i am using in controller.
Please help me to correct it.Advance Thanks
I hope this can help you.
class PathToClass_ClassName extends Zend_Db_Table_Abstract
{
/*$_name is zend global for selecting db table*/
protected $_name = 'contsize';
public function paginationZend()
/*$this->select() by default selectingall records from database*/
$SELECT = $this->SELECT();
$result = $this->fetchAll($SELECT);
$page=$this->_getParam('page',1);
$paginator = Zend_Paginator::factory($result);
$paginator->setItemCountPerPage(10);
$paginator->setCurrentPageNumber($page);
$this->view->paginator=$paginator;
}
Than you can call your function where you want.
I can't seem to get ZF2 to show just one error message for failed form validation messages.
For example, an EmailAddress validator can pass back up to 7 messages and typically shows the following if the user has made a typo:
oli.meffff' is not a valid hostname for the email address
The input appears to be a DNS hostname but cannot match TLD against known list
The input appears to be a local network name but local network names are not allowed
How can I override the error to show something a little more friendly, such as "Please enter a valid email address" instead of specifics like the above?
OK, managed to come up with a solution for this. Instead of using the same string as the error for all validator failures as Sam suggested above, I have overridden the error messages in the InputFilter for the elements and then used a custom form error view helper to show only the first message.
Here is the helper:
<?php
namespace Application\Form\View\Helper;
use Traversable;
use \Zend\Form\ElementInterface;
use \Zend\Form\Exception;
class FormElementSingleErrors extends \Zend\Form\View\Helper\FormElementErrors
{
/**
* Render validation errors for the provided $element
*
* #param ElementInterface $element
* #param array $attributes
* #throws Exception\DomainException
* #return string
*/
public function render(ElementInterface $element, array $attributes = array())
{
$messages = $element->getMessages();
if (empty($messages)) {
return '';
}
if (!is_array($messages) && !$messages instanceof Traversable) {
throw new Exception\DomainException(sprintf(
'%s expects that $element->getMessages() will return an array or Traversable; received "%s"',
__METHOD__,
(is_object($messages) ? get_class($messages) : gettype($messages))
));
}
// We only want a single message
$messages = array(current($messages));
// Prepare attributes for opening tag
$attributes = array_merge($this->attributes, $attributes);
$attributes = $this->createAttributesString($attributes);
if (!empty($attributes)) {
$attributes = ' ' . $attributes;
}
// Flatten message array
$escapeHtml = $this->getEscapeHtmlHelper();
$messagesToPrint = array();
array_walk_recursive($messages, function ($item) use (&$messagesToPrint, $escapeHtml) {
$messagesToPrint[] = $escapeHtml($item);
});
if (empty($messagesToPrint)) {
return '';
}
// Generate markup
$markup = sprintf($this->getMessageOpenFormat(), $attributes);
$markup .= implode($this->getMessageSeparatorString(), $messagesToPrint);
$markup .= $this->getMessageCloseString();
return $markup;
}
}
It's just an extension of FormElementErrors with the render function overridden to include this:
// We only want a single message
$messages = array(current($messages));
I then insert the helper into my application using the solution I posted to my issue here.
I followed Rob Allens ZF 1 Tutorial and wanted to pimp it up with some UnitTesting. But whenever I run the phpunit command, i get the message:
here was 1 failure:
1) IndexControllerTest::testDeleteAction
Failed asserting last controller used <"error"> was "Index"
/path/to/library/Zend/Test/PHPUnit/ControllerTestCase.php:1000
/path/to/tests/application/controllers/IndexControllerTest.php:55
FAILURES!
Tests: 4, Assertions: 9, Failures: 1.
The Action in question is the deleteAction and looks like this:
public function deleteAction() {
if ($this->getRequest()->isPost()) {
$del = $this->getRequest()->getPost('del');
if ($del == 'Yes') {
$id = $this->getRequest()->getPost('id');
$wishes = new Application_Model_DbTable_Wishes();
$wishes->deleteWish($id);
}
$this->_helper->redirector('index');
}
else {
$id = $this->_getParam('id', 0);
$wishes = new Application_Model_DbTable_Wishes();
$this->view->wish = $wishes->getWish($id);
}
}
I tracked the error down to be $wishes>getWish($id); so if i go to that function, that looks like this:
public function getWish($id) {
$id = (int) $id;
$row = $this->fetchRow('id = ' . $id);
if(!$row){
throw new Exception("Could not find row $id");
}
return $row->toArray();
}
it appears the line $row = $this->fetchRow('id = ' . $id); causes the problem. And I can't figure out why. All action work just fine, they do as expected.Any idea how to fix this?
Thanks!
Maybe try using the select() object instead if a plain string:
public function getWish($id) {
$id = (int) $id;
$select = $this->select();
$select->where('id = ?', $id);
$row = $this->fetchRow($select);
if(!$row){
throw new Exception("Could not find row $id");
}
return $row->toArray();
}
This just a wild guess, but who knows. The only thing that looks at all odd is the lack of a placeholder in the query string (?).
FetchRow() does like to work with the select() object, in fact if you pass a string the first thing fetchRow() does is build a select(). So maybe it just doesn't like the string.
I cant see my error of Sql. It cuts my queries, and the error is meaningless except it informs there is an error.
Like
error in statement "select * from o.."
how can I get full query, so i can investigate how the error occured?
I previously wrote a sql function that throws debugging string if sql has error. I though zend'ers have needed and there should exists a code:
if(($error = mysql_error($conn)){
$cagiri=debug_backtrace();
$i=count($cagiri);
And says
[Caller__Function__] => dbSave
[Caller__Class__] => classBasic
[Arguments] => Array
(
[0] => function : loadLinks
[1] =>
[1] => sql error: Duplicate entry 'http://www.istanbulboncugu.com/Lokma' for key 'url'
[2] => query: insert into downloadLinks set `title`= 'Lokma : İstanbul - Avrupa', `url`= 'http://www.istanbulboncugu.com/Lokma', `site`= 'rssSehirFirsati', `status`= 'new'
So I dont dig 30 query, if there is error,
Error string shows function that composed the query. Etc.
I think Zend have lacks that kind of awareness.
I know zend not prefers hard and log path against smart ways ?!?
I start using that code, if there is error.
function results($q){
$results = Array();
try{
$results = $this->_db->query($q)->fetchAll();
}catch(Exception $e){
var_dump($q);
die($e->getMessage());
}
return $results;
}
If you are using Zend_Db_Select you can get the full created query by doing
$select->__toString();
In reply to your comment, this is how you can get the SQL error message:
try {
$this->db->insert('Users', $array );
} catch (Exception $e){
echo $e->getMessage();
}
