I want to insert data into my database. I am using codeigniter framework to build my app.
When I click on submit button,It don't give any error just reload the same page and data in not inserted in database.
Following my code to insert data into database -
public function addSale($saleDetails = array(), $items = array(), $warehouse_id)
{
foreach($items as $data){
$product_id = $data['product_id'];
$product_quantity = $data['quantity'];
$this->updateProductQuantity($product_id, $warehouse_id, $product_quantity);
}
// sale data
$saleData = array(
'reference_no' => $saleDetails['reference_no'],
'warehouse_id' => $warehouse_id,
'biller_id' => $saleDetails['biller_id'],
'biller_name' => $saleDetails['biller_name'],
'customer_id' => $saleDetails['customer_id'],
'customer_name' => $saleDetails['customer_name'],
'date' => $saleDetails['date'],
'note' => $saleDetails['note'],
'internal_note' => $saleDetails['internal_note'],
'inv_total' => $saleDetails['inv_total'],
'total_tax' => $saleDetails['total_tax'],
'total' => $saleDetails['total'],
'total_tax2' => $saleDetails['total_tax2'],
'tax_rate2_id' => $saleDetails['tax_rate2_id'],
'inv_discount' => $saleDetails['inv_discount'],
'discount_id' => $saleDetails['discount_id'],
'user' => $saleDetails['user'],
'shipping' => $saleDetails['shipping']
);
if($this->db->insert('sales', $saleData)) {
$sale_id = $this->db->insert_id();
$addOn = array('sale_id' => $sale_id);
end($addOn);
foreach ( $items as &$var ) {
$var = array_merge($addOn, $var);
}
if($this->db->insert_batch('sale_items', $items)) {
return true;
}
}
return false;
}

Based on https://ellislab.com/codeigniter/user-guide/database/examples.html , it seems to me, that you are missing a line -> $this->db->insert('sales', $saleData); . You do have it inside an if statement, but if statement will not execute it as a code, but check if it returns true.
$saleData = array(
'reference_no' => $saleDetails['reference_no'],
'warehouse_id' => $warehouse_id,
'biller_id' => $saleDetails['biller_id'],
'biller_name' => $saleDetails['biller_name'],
'customer_id' => $saleDetails['customer_id'],
'customer_name' => $saleDetails['customer_name'],
'date' => $saleDetails['date'],
'note' => $saleDetails['note'],
'internal_note' => $saleDetails['internal_note'],
'inv_total' => $saleDetails['inv_total'],
'total_tax' => $saleDetails['total_tax'],
'total' => $saleDetails['total'],
'total_tax2' => $saleDetails['total_tax2'],
'tax_rate2_id' => $saleDetails['tax_rate2_id'],
'inv_discount' => $saleDetails['inv_discount'],
'discount_id' => $saleDetails['discount_id'],
'user' => $saleDetails['user'],
'shipping' => $saleDetails['shipping']
);
$this->db->insert('sales', $saleData);
This should work. You can also check if it succeeds like this ->
return ($this->db->affected_rows() != 1) ? false : true;
