I am new to codeiginter,how to insert the data into table using codeiginter
my controller code;
$data = array(
'subgrpname' => $this->input->post('subgrpname'),
'grpname'=> $this->input->post('grpname'),
'pltype'=> $this->input->post('pltype')
);
It is simple form use internet to search it
$data = array(
'subgrpname' => $this->input->post('subgrpname'),
'grpname'=> $this->input->post('grpname'),
'pltype'=> $this->input->post('pltype')
);
$this->db->insert('tablename',$data);
I would like to share reusable code approach by following the MVC coding style
My Controller
$table = 'table_name';
$data = array(
'subgrpname' => $this->input->post('subgrpname'),
'grpname'=> $this->input->post('grpname'),
'pltype'=> $this->input->post('pltype')
);
$record_id = $this->Common_Model->insert_into_table($table, $data);
My Common_Model
function insert_into_table($table, $data) {
// echo "<pre>";print_r($data);exit;
$insert = $this->db->insert($table, $data);
$insert_id = $this->db->insert_id();
if ($insert) {
return $insert_id;
} else {
return false;
}
}
You can use this model function as much time as you want.

I am copying this code in Codeigniter official docs, but I don't know why this will throw an error
public function acceptChangeRequest($id,$data1,$accept) {
$data = array(
'status' => $accept,
'approve_by' => $data1,
);
$this->db->where('id', $id);
$this->db->update('change_request',$data);
//return true;
}
Error Number: 1054
Unknown column 'Array' in 'field list'
UPDATE change_request SET status = 'Y', approve_by = Array WHERE id = '22'
It sounds wierd since this code works in my other function. Any idea?
Read The Documentation Clearly
Read About Update Records In Codeigniter
Here IS Demo Function For You
public function updateBasic($data,$user_id){
$userData=array(
'marital_status'=>$data['marital_status'],
'country'=>$data['stateofresidence'],
'city'=>$data['city'],
'caste'=>$data['caste'],
'residential_status'=>$data['residencystatus']
);
$this->db->WHERE('user_id',$user_id)->update('basic_profile',$userData);
return true;
}
You Must Check Through Print_r();what Is coming To your Function In Your Case $data1 Is Coming In the From OF array You Must Extract The Array To Update The Record
Use this function in your model to update the record.
public function acceptChangeRequest($where, $table, $data){
$this->db->where($where);
$this->db->update($table, $data);
return $this->db->affected_rows() > 0;
}
use this code in your controller.
$where = array('id'=>$id);
$data = array(
'status' => $accept,
'approve_by' => $data1,
);
$this->User_model->update($where,'table_name',$data);
What is in your $data1 variable? I can see that it's an array, and that is the problem.
If your $data1 stores indexes like in your table's row, than this is the possible solution for you:
public function acceptChangeRequest($id,$data1,$accept) {
$data1["status"] = $accept;
$this->db->where('id', $id);
$this->db->update('change_request', $data1);
return true;
}
But if your $data1 variable stores only the approve_by information, than your possible solution is:
public function acceptChangeRequest($id,$data1,$accept) {
$data = array(
'status' => $accept,
'approve_by' => $data1["approve_by"]
);
$this->db->where('id', $id);
$this->db->update('change_request', $data);
return true;
}
First of all, you need to know what you expect from $data1, than you can move forward to the solution.
You can see your $data1 variable in your Controller's function:
print "<pre>";
print_r($data1);
print "<pre>";
die();
http error occured while calling data from model using function
model
public function getProductCombo() {
$q = $this->db->get_where('products', array('type' => 'combo'));
if ($q->num_rows() > 0) {
foreach (($q->result()) as $row) {
$data[] = $row;
}
return $data;
}
}
controller
function sets() {
$this->sma->checkPermissions();
$this->load->helper('security');
$this->data['error'] = (validation_errors() ? validation_errors() :
$this->session->flashdata('error'));
// problem in this line also
$this->data['showcombo'] = $this->load->sales_model->getComboProduct();
$bc = array(array('link' => base_url(),
'page' => lang('home')),
array('link' => site_url('sales'),
'page' => lang('products')),
array('link' => '#', 'page' => "sets")
);
$meta = array('page_title' => "Add Sets", 'bc' => $bc);
$this->page_construct('sales/sets', $meta, $this->data);
}
First of all, No need to include the curly braces for $q->result
foreach ($q->result as $row)
{
$data[] = $row;
}
No need to use validation_errors in your php file.You can directly load your form page.Use validation_errors() in view page.
In your Controller, do this
if ($this->form_validation->run() == FALSE)
{
$this->load->view('myform');
}
Then in your formpage you can echo
<?php echo validation_errors(); ?>
change this line to
$this->data['showcombo'] = $this->load->sales_model->getComboProduct();
this
$this->data['showcombo'] = $this->load->sales_model->getProductCombo();
Because your
model name is
public function getProductCombo()
{
}
Firstly you load model in controller. And then called function, which you have defined in model..
$this->load->model('sales_model','sales'); // sales is alias name of model name
$this->data['showcombo'] = $this->sales->getComboProduct();
I m trying to delete my db table row using below code from observer. but can't delete it gives error in system log
Some transactions have not been committed or rolled back
$customFieldValue = $this->_getRequest()->getPost();
//$groupCodeArray = $customFieldValue['product']['customer_group_ids'];
$DataCollectionDel = Mage::getModel('customerspecificproduct/customerspecificproduct')->getCollection()->addFieldToFilter(
'product_ids',
array(
'eq'=>$product->getId()
)
)->addFieldToFilter(
'group_id',
array(
'notnull'=>true,
)
);
if($DataCollectionDel){
foreach($DataCollectionDel as $data){
$deleteRow = Mage::getModel('customerspecificproduct/customerspecificproduct')->load($data->getId())->delete();
}
}exit;
I found solution myself
$DataCollectionDel = Mage::getModel('customerspecificproduct/customerspecificproduct')->getCollection()->addFieldToFilter(
'product_ids',
array(
'eq'=>$product->getId()
)
)->addFieldToFilter(
'group_id',
array(
'notnull'=>true,
)
);
try{
if($DataCollectionDel){
foreach($DataCollectionDel as $data){
$data->delete();
}
}
I found solution for it :3 without getCollection().
Model
public function deleteByCondition($itemId,$vendor)
{
return $this->getResource()->deleteByCondition($itemId,$vendor);
}
Resource Model
public function deleteByCondition($itemId,$vendor)
{
$table = $this->getMainTable();
$where = array();
$where[] = $this->_getWriteAdapter()->quoteInto('item_id = ?',$itemId);
$where[] = $this->_getWriteAdapter()->quoteInto("vendor = ? ", $vendor);
$result = $this->_getWriteAdapter()->delete($table,$where);
return $result;
}
I work with CakePHP 2.0. I made a new function sort and had no problem, if I take the table fields. But if I want to calculate something and give the result (method: 'Participant.year'=>'calculateyear' ) in my sort method, I have no result on my view.
function sort() {
$participants = $this->Participant->find('all', array(
'conditions'=>array('Participant.sex'=>'m','Participant.year'=>'calculateyear'),
'order'=>array('Participant.communitieRank'=>'ASC','Communitie.name'=>'ASC')
));
$this->set('participants', $participants);
}
function calculateyear ($jahr) {
$jahr = '2000';
return $jahr;
}
assuming you are in your PartecipantsController I guess what you want to do is:
function sort() {
$participants = $this->Participant->find('all', array(
'conditions'=>array(
'Participant.sex'=>'m',
'Participant.year'=> $this->calculateyear(2000)
),
'order'=>array('Participant.communitieRank'=>'ASC','Communitie.name'=>'ASC')
));
$this->set('participants', $participants);
}
but your question is not clear at all
thats my solution, it works :)
function calculateyear ($year) {
$today = date("Y");
$year = $today - $year;
return $year;
}
function kat1w() {
$participants = $this->Participant->find('all', array(
'conditions'=>array('Participant.sex'=>'f',
'Participant.year >='=>$this->calculateyear(9)),
'order'=>array('Participant.communitieRank'=>'ASC','Communitie.name'=>'ASC')
));
$this->set('participants', $participants,$this->Paginator->paginate());
}
I'm newbie in codeigniter and still learning. Anyone can help for sample in basic view, add, update, delete operation and queries in codeigniter will gladly appreciated.
Just a simple one like creating addressbook for newbie.
thanks,
best regards
Some sample queries in Codeigniter
class Names extends Model {
function addRecord($yourname) {
$this->db->set("name", $yourname);
$this->db->insert("names");
return $this->db->_error_number(); // return the error occurred in last query
}
function updateRecord($yourname) {
$this->db->set("name", $yourname);
$this->db->update("names");
}
function deleteRecord($yourname) {
$this->db->where("name", $yourname);
$this->db->delete("names");
}
function selectRecord($yourname) {
$this->db->select("name, name_id");
$this->db->from("names");
$this->db->where("name", $yourname);
$query = $this->db->get();
return $this->db->result();
}
function selectAll() {
$this->db->select("name");
$this->db->from("names");
return $this->db->get();
}
}

You can use this as an example
class Crud extends Model {
// selecting records by specifying the column field
function select()
{
// use $this->db->select('*') if you want to select all the records
$this->db->select('title, content, date');
// use $this->db->where('id', 1) if you want to specify what row to be fetched
$q = $this->db->get('mytable');
// to get the result
$data = array();
// for me its better to check if there are records that are fetched
if($q->num_rows() > 0) {
// by doing this it means you are returning array of records
foreach($q->result_array() as $row) {
$data[] = $row;
}
// if your expecting only one record will be fetched from the table
// use $row = $q->row();
// then return $row;
}
return $data;
}
// to add record
function add()
{
$data = array(
'title' => 'My title' ,
'name' => 'My Name' ,
'date' => 'My date'
);
$this->db->insert('mytable', $data);
}
// to update record
function update()
{
$data = array(
'title' => $title,
'name' => $name,
'date' => $date
);
$this->db->where('id', 1);
$this->db->update('mytable', $data);
}
// to delete a record
function delete()
{
$this->db->where('id', 1);
$this->db->delete('mytable');
}
}
Some of this are from codeigniter userguide.
To view the records,
If return data is array of records,
foreach($data as $row)
{
echo $row['title'] . "<br />";
}
If the return data is an object (by using $q->row),
echo $data->title;
This is just a few examples or CRUD in Codeigniter. Visit the codeigniter userguide.
