i want to check cpt code is already exist in db or not in update form..
so,First i'm checking all cpt codes present in database except post one now i'm getting result without post cpt code....now I want check cpt code from first query result.
my function in controller
public function updatedDxCodeExist()
{
$this->load->model('MedicineModel');
$Id = $this->input->post("Id");
$dxCode = $this->input->post("dxCode");
if(empty($Id))
{
$result = $this->MedicineModel->updatedDxCodeExist($dxCode);
} else {
$result = $this->MedicineModel->updatedDxCodeExist($dxCode, $Id);
}
if(empty($result))
{
echo("true");
}
else
{
echo("false");
}
}
my function in model
public function updatedDxCodeExist($dxCode, $Id =0)
{
$this->db->select("dx_code");
$this->db->from("dx_codes");
$this->db->where('dx_code !=',$dxCode);
$query = $this->db->get();
return $query->result();
}
Actually you can use like this:
if($result->num_row() <= 0 )
{
echo("true");
}
else
{
echo("false");
}
You can use array_search function in codeigniter

I am using codeigniter. Now i have id in a variable in one method of a model. I want to access the value where i used the variable for entire model(ie, all function of a model).
Controller:::
public function user_id()
{
if(!empty($_POST['name']))
{
if(isset($_POST['name']))
{
$name =$this->input->post('name'); //echo "Posted:".$name;
$this->UserRight_model->get_id($name);
}
}
}
Moldel code:
public function get_id($name)
{
$query = $this->db->query("select UserPcKey from UserMaster where UserName='".$name."'");
if ($query->num_rows() > 0)
{
foreach ($query->result() as $row)
{
$id= $row->UserPcKey;
echo $pckey;
}
}
else
{
echo "choose valid name";
}
}
I tried to use the id value in other function in a same model i got error due to parameter.
My Model code is given below.
public function getattendence($data)
{
$sql="CALL `sp_AttendanceDetails`(?,?,?);";
$query=$this->db->query($sql,$data);
return $query->result_array();
}
But it return one result set.The second result set i not get..
Pass data like this
public function getattendence($data)
{
# example of your $data array
$id = $data['id'];
$name = $data['name'];
$date = $data['date'];
$sql="CALL sp_AttendanceDetails($id,'$name',$date);";
$query=$this->db->query($sql);
return $query->result_array();
}
Use return $this->_execute_multi_query($sql);

i am getting error Call to a member function row() on a non-object in codeigniter my controller is
public function edit_survey_pro($id)
{
$id = intval($id);
$survey = $this->model->get("surveys",array("ID" => $id),100000);
if (sizeof($survey) == 0) $this->template->error(lang("error_32"));
$this->template->loadContent("user/edit_survey_pro", array(
"survey" => $survey->row()
)
);
}
my model is
function get($table,$where='',$perpage=0,$start=0,$order_by='',$arr='')
{
$this->db->from($table);
if($perpage != 0 && $perpage != NULL)
$this->db->limit($perpage,$start);
if($where){
$this->db->where($where);
}
if($order_by){
$this->db->order_by($order_by);
}
if($arr=='')
$query = $this->db->get()->result();
else
$query = $this->db->get()->result('array');
if(!empty($query))
if($perpage != 0 && $perpage != NULL)
$result = $query;
else
$result = $query[0];
else
$result = array();
return $result;
}
here loadContent() is just load the content with view path
public function loadContent($view,$data=array(),$die=0){
//something to load the content
}
in my model I am getting the result as an array of object in $query and then it is returned as $result like this -
$query = $this->db->get()->result(); but at the controller $survey stores array of object and i want to show the content of that array of object ,previously I use
$this->template->loadContent("user/edit_survey_pro", array(
"survey" => $survey->row()
)
);
to get that data but the problem is $survey->row() cannot return that data bcoz it is not an object it is array of object so it can't be returned through row() method
so instead of this I just call the first element of that data like this-
$this->template->loadContent("user/edit_survey_pro", array(
"survey" => $survey[0]
)
);
Somehow its works for me bcoz I want to show the first row of the data
if sembody wants to show all data then I think he shuld try logic to increment the key value of that array of object for me it is $survey[] you can use foreach loop for increment the of value of the key element
The problems i see are your model, I will dissect it and add comments to your original code to point out the issues:
function get($table,$where='',$perpage=0,$start=0,$order_by='',$arr='')
//above there are problems, you are setting some of your parameters to
//equal blank, but below, in your conditionals, you are checking if they
// exist. They will always exist if they are set to blank. Fix them by
// setting them = NULL like this:
// get($table,$where=null,$perpage=0,$start=0,$order_by=null,$arr=null)
{
$this->db->select();// <-- you forgot this
$this->db->from($table);
if($perpage != 0 && $perpage != NULL)
//when will $perpage = null? , if never, then you dont need it.
$this->db->limit($perpage,$start);
if($where){
//change this to if(isset($where)). Also why do you use
//curly braces here, but not in the above if statement if only
//one line is affected in your if. I would remove the
//curly braces here.
$this->db->where($where);
}
if($order_by){
// change this to if(isset($order_by)). Same thing as
//above about the curly braces here
$this->db->order_by($order_by);
}
if($arr=='')
// change this to if(isset($arr)).
$query = $this->db->get()->result();
else
$query = $this->db->get()->result('array');
//change this to: $query = $this->db->get()->result_array();
if(!empty($query))
//change the above to if($query->num_rows > 0). Also, here since
//your code body is longer then one line, you will need curly braces
//around your if statement
if($perpage != 0 && $perpage != NULL)
//again, will $perpage ever be NULL? However, why do you need
//this conditional at all, if the limit above is already
//doing this job?
$result = $query;
else
$result = $query[0];
else
$result = array();
return $result;
}
after applying all the changes:
MODEL:
function get($table, $where=null, $perpage=0, $start=0, $order_by=null, $arr=null)
{
$this->db->select();
$this->db->from($table);
if($perpage != 0)
$this->db->limit($perpage, $start);
if(isset($where))
$this->db->where($where);
if(isset($order_by))
$this->db->order_by($order_by);
if(isset($arr)) {
$result = $this->db->get()->result_array();
} else {
$result = $this->db->get()->result();
}
return $result;
}
CONTROLLER
public function edit_survey_pro($id) {
$id = intval($id);
$survey = $this->model->get("surveys",array("ID" => $id),100000);
if (!$survey) {
$this->template->error(lang("error_32"));
} else {
$data["survey"] = $survey;
$this->template->loadContent("user/edit_survey_pro", $data);
}
}
I think when you use $this->db->get(), you need to pass the table name as param like this:
$this->db->get('table_name')->result();
Is there a way to show the changed values after saving within the Joomla save method?
For example, when I edit a "maxuser" field and save it, I´d like to show the old and the new value.
I tried this by comparing "getVar" and "$post", but both values are the same.
function save()
{
...
$maxuser1 = JRequest::getVar('maxuser');
$maxuser2 = $post['maxuser'];
...
if($maxuser1 != $maxuser2) {
$msg = "Not the same ...";
}
...
}
It's better to override JTable, not the Model. Heres sample code:
public function store($updateNulls = false) {
$oldTable = JTable::getInstance(TABLE_NAME, INSTANCE_NAME);
$messages = array();
if ($oldTable->load($this->id)) {
// Now you can compare any values where $oldTable->param is old, and $this->param is new
// For example
if ($oldTable->title != $this->title) {
$messages[] = "Title has changed";
}
}
$result = parent::store($updateNulls);
if ((count($messages) > 0) && ($result === true)){
$message = implode("\n", $messages);
return $message;
} else {
return $result;
}
}
This will return message string if there are any, true if there are no messages and save succeeded and false if saving failed. So all you have to do is check returned value in model and set right redirect message.
In the controller you can use the postSaveHook which gives you access to the validated values.
I do have a question : I cannot pass the data from model to controller
You can see some of my codes, please help me.
It does not work!
this is my model "mymodel.php"
....
$query = $this->db->query("SELECT * FROM `rand` WHERE `used` = 0 LIMIT 0, 1");
if($query){
foreach ($query->result() as $row);
}
$t = "EXAMPLE/{$row->code}";
function wandad() {
return $t;
}
.....
and this is my controller mycont.php
...
$this->load->model('mymodel');
$data['new'] = $this->Mymodel->wandad();
$this->load->view('myview',$data);
...
and this is my view myview.php
....
echo $new;
.....
Clearly you The model is not written properly and to corrent this simple do this
1.) I put a default value on $t
2.) I put the query >> loop on the inside function
wandad
so it can be executed once called from controller
function wandad() {
$query = $this->db->query("SELECT * FROM `rand` WHERE `used` = 0 LIMIT 0, 1");
$t = "";
if($query){
foreach ($query->result() as $row){
$t = "EXAMPLE/{$row->code}".'<br>';
}
}
return $t;
}
Here are several issues into your model
Your Foreach function doesn't do anything
$t is not in the same namespace than wandad()
Function wandad is not defined into your model class
I'm not sure of what you wanna get with wandad() function but here's a pattern.
function yourFunction()
{
/* This will return the full query as an array */
$query = $this->db->query("SELECT * FROM `rand` WHERE `used` = 0 LIMIT 0, 1")->result_array();
/* Store variable in the same class */
$this->t = "EXAMPLE/".$query[0]['code'];
/* Close yourFunction() */
}
public function wandad() {
return $this->t;
}
Then into your controller, do that instead :
$this->load->model('mymodel');
$this->mymodel->yourFunction();
$data['new'] = $this->mymodel->wandad();
$this->load->view('myview',$data);
#Touki his foreach actually does something. It will set the variable $row with the last row that is returned from the query. Not the best way to do it ... But it's a way. Better would be to use a limit in the query.
There is a small mistake in your code #Ernesto.that is
foreach ($query->result() as $row){
$t. = "EXAMPLE/{$row->code}".'<br>';
}
but your code was simply nice
