hello i want to update the row by clicking on edit button, but it giving me this error, kindly help
function updateUser()
{
$data = stripslashes(file_get_contents("php://input"));
$mydata = json_decode($data, true);
$id = $mydata['sid'];
//retrieve specific info
$sql = "SELECT * FROM admin WHERE id = {$id}";
$result = $this->db->query($sql);
$row = $result->fetch_assoc();
echo json_encode($row); //returning json formate
}
Use $result->row_array(); instead of $result->fetch_assoc();
To prevent sql injection, you may also want to bind the $id separately instead of concatenating it into the query, like this:
$sql = "SELECT * FROM admin WHERE id = ?";
$result = $this->db->query($sql, array($id));
$row = $result->row_array();

I have sql query in controller, this query produces number of rows.
$q1 = $this->db->query("SELECT product_code,product_quantity FROM tbl_order_details WHERE order_id='$order_no' AND location='$location'")->row();
foreach($q1 as $v_barcode){
$result = $this->settings_model->update_cancel_stock($v_barcode->product_code,$v_barcode->product_quantity);
}
then i pass this data to my model,
public function update_cancel_stock($code,$qty)
{
$this->db->set('product_quantity', $qty , FALSE);
$this->db->where('product_id', $order );
$this->db->update("tbl_inventory6");
}
but no any update. please check above code. thanx
Try this
$cond = array("order_id" => $order_no, "location" => $location);
$q1 = $this->db->select("product_code,product_quantity")->from("tbl_order_details")->where($cond)->row();
$result = $this->settings_model->update_cancel_stock($q1->product_code,$q1->product_quantity);
and then model ($code was not used)
public function update_cancel_stock($code,$qty){
$this->db->set('product_quantity', $qty , FALSE);
$this->db->where('product_id', $code);
$this->db->update('tbl_inventory6');
}
You are using row() function of Active Record. It already return only one row. So there is no requirement of foreach. Try this:
$q1 = $this->db->query("SELECT product_code,product_quantity FROM tbl_order_details WHERE order_id='$order_no' AND location='$location'")->row();
$result = $this->settings_model->update_cancel_stock($q1->product_code,$q1->product_quantity);
If you are getting multiple records and you are using foreach, you should use result().
$q1 = $this->db->query("SELECT product_code,product_quantity FROM tbl_order_details WHERE order_id='$order_no' AND location='$location'")->result();
foreach($q1 as $v_barcode){
$result = $this->settings_model->update_cancel_stock($v_barcode->product_code,$v_barcode->product_quantity);
}
How to use:
JFactory::getDbo()->insertObject('#__card_bonus', $object);
with on duplicate key update ?
You have a few options:
1) Check for an entity id. This is my preferred option, because it only uses a single query, is reusable for any object, and is database agnostic - meaning it will work on whichever DBMS you choose, whereas the other two options are exclusive to MySQL.
if (isset($object->id)) {
$db->updateObject('#__card_bonus', $object);
}
else {
$db->insertObject('#__card_bonus', $object, 'id');
}
I often create an abstract model with a save(stdClass $object) method that does this check so I don't have to duplicate it.
2) Write your own query using the MySQL ON DUPLICATE KEY UPDATE syntax, which is a proprietary extension to the SQL standard, that you have demonstrated understanding of.
3) Write your own query using MySQL's proprietary REPLACE INTO extension.
<?php
$jarticle = new stdClass();
$jarticle->id = 1544;
$jarticle->title = 'New article';
$jarticle->alias = JFilterOutput::stringURLSafe($jarticle->title);
$jarticle->introtext = '<p>re</p>';
$jarticle->state = 1;
$jarticle->catid = 13;
$jarticle->created_by = 111;
$jarticle->access = 1;
$jarticle->language = '*';
$db = JFactory::getDbo();
try {
$query = $db->getQuery(true);
$result = JFactory::getDbo()->insertObject('#__content', $jarticle);
}
catch (Exception $e){
$result = JFactory::getDbo()->updateObject('#__content', $jarticle, 'id');
}
I use this method - are not fully satisfied, but ...
or for not object method:
$query = $db->getQuery(true);
$columns = array('username', 'password');
$values = array($db->quote($username), $db->quote($password));
$query
->insert($db->quoteName('#__db_name'))
->columns($db->quoteName($columns))
->values(implode(',', $values));
$query .= ' ON DUPLICATE KEY UPDATE ' . $db->quoteName('password') . ' = ' . $db->quote($password);
$db->setQuery($query);
JFactory::getDbo()->insertObject('#__card_bonus', $object, $keyName);
The name of the primary key. If provided the object property is updated.
Joomla doc ...
i have a search field and i want to show the results with pagination.
every thing works well in first result page but in other pages there is noting to show without any errors and when back to first page also there is noting.
i putted the posted key in session to avoid losing it.
but still noting.
this is my controller:
public function search()
{
$this->session->set_userdata('searched',$this->input->post('searchterm'));
$searchterm = $this->session->userdata('searched');
$limit = ($this->uri->segment(3) > 0)?$this->uri->segment(3):0;
$config['base_url'] = base_url() . 'home/search';
$config['total_rows'] = $this->home_model->search_record_count($searchterm,$language);
$config['per_page'] = 10;
$config['uri_segment'] = 3;
$config['display_pages'] = TRUE;
$choice = $config['total_rows']/$config['per_page'];
$config['num_links'] = 3;
$this->pagination->initialize($config);
$data['results'] = $this->home_model->search($searchterm,$limit,$language);
$data['links'] = $this->pagination->create_links();
$data['searchterm'] = $searchterm;
$data['total']= $this->home_model->search_record_count($searchterm,$language);
putHeader();
putTop();
putTopmenu();
putSearch($data);
putFooter();
}
this is my model:
public function search_record_count($searchterm)
{
$sql = "SELECT COUNT(*) As cnt FROM content WHERE body LIKE '%" . $searchterm . "%'";
$q = $this->db->query($sql);
$row = $q->row();
return $row->cnt;
}
public function search($searchterm,$limit)
{
$data = $this->db
->select('content.title,content.id,content.category,content.body,path')
->from('content')
->join('categories','noor_content.category = categories.id')
->like('noor_content.title', $searchterm)
->like('noor_content.body', $searchterm)
->limit("5")
->order_by("content.id","DESC")
->get();
if($data->num_rows() > 0)
{
return $data->result();
//print_r($data);exit();
}
else
{
return 0;
}
}
The problem is that you are not limiting your query according to the pagination. In your controller you are getting the 3rd URL segment
$limit = ($this->uri->segment(3) > 0)?$this->uri->segment(3):0;
And passing it to you model but then you are not doing anything with it. In your model you want to do something like
$data = $this->db
->select('content.title,content.id,content.category,content.body,path')
->from('content')
->join('categories','noor_content.category = categories.id')
->like('noor_content.title', $searchterm)
->like('noor_content.body', $searchterm)
->limit("10, " . $limit) //Edited this line
->order_by("content.id","DESC")
->get();
i think you should use method = 'get' instead of post... i mean some thing like this ..
<form method="get" action="your_controller/your_function">
//your search form
</form>
by using get instead of post u dont have to use any session variables and u can easily access them in your controller as
$this->input->get('feild_name');
moreover u wont have problem with second page or any other page in pagination as all the search feilds get attached in the url and u can access it easily using $this->input->get('feild_name'); untill your url is changes to something else.. i will aslo save u al ot of coding ..
I'm wonder how can I get custom attribute,
My custom attribute call "tim_color"
I was try get by $_product->getAttributeText('tim_color');
after execute I get fatal error Call to a member function getAttributeText() on a non-object
when I'm used
$data['color'] = $product->getTim_color();
in the result i'm get id, but I need the name of atrribute, how can I resolve this problem
My code of script:
$mage_csv = new Varien_File_Csv(); //mage CSV
$products_model = Mage::getModel('catalog/product')->getCollection();; //get products model
$products_model ->addAttributeToSelect('*');
$products_row = array();
foreach ($products_model as $prod)
{
#print_r($prod);
$product = Mage::getModel('catalog/product')->load($prod->getId());
$data = array();
$data['id_product'] = $product->getId();
$data['color'] = $product->getTim_color();
$data['sku'] = $product->getSku();
$data['name'] = strip_tags($product->getName());
$data['description'] = trim(preg_replace('/\s+/', ' ', strip_tags($product->getDescription())));
$data['price'] = $product->getPrice();
$products_row[] = $data;
}
thx for help
Try,
$_product->getData(’tim_color’);
I hope you can get the attribute value by getAttributeText() also. Check out,
$_product = Mage::getModel('catalog/product')->load($item->getId()); //getting product
$_product->getAttributeText('tim_color'); //getting custom attribute value
Detailed discussions are here and here.
$select = "SELECT * FROM `jos_users`";
$connection->setQuery($select);
$rows = $connection->getNumRows();
$rows does not work it throws the 'mysql_num_rows(): supplied argument is not a valid' error but...
$result = $connection->loadObjectList();
$result works fine.
Is this a Joomla bug?? Or what am i doing wrong?
<?
$select = "SELECT * FROM `jos_users`";
$connection->setQuery($select);
//add this:
$connection->query();
$rows = $connection->getNumRows();
?>
You're setting the query but not executing it.
would it need to call query()... $res = $db->query('select * from jos_users'); $db->getNumRows($res);
