codeigniter how to show data in functions - codeigniter

My model:
function get_data($id)
{
$this->db->select('id, Company, JobTitle');
$this->db->from('client_list');
$this->db->where('id', $id);
$query = $this->db->get();
return $query->result();
}
I want to get the the data from get_data(), is this the right way?
public function show_data( $id )
{
$data = $this->get_data($id);
echo '<tr>';
echo '<td>'.$data['Company'].'</td>';
echo '<td>'.$data['JobTitle'].'</td>';
echo '<td>'.$data['id'].'</td>';
echo '<td></td>';
echo '</tr>';
}

Use the row_array() function to get the data in the array format.
Reference url
http://ellislab.com/codeigniter/user-guide/database/results.html

you can use foreach loop to print
foreach ($data->result() as $row)
{
echo '<tr>';
echo '<td>'.$row['Company'].'</td>';
echo '<td>'.$row['JobTitle'].'</td>';
echo '<td>'.$row['id'].'</td>';
echo '<td></td>';
echo '</tr>';
}
thank you

just to improve answer, I use "general_model" for all my controllers, there are some exceptions where I need special queries, I just create desired model so "general_model" stays same and I can use it in any project.
e.g.
general_model.php
function _getWhere($table = 'table', $select = 'id, name', $where = array()) {
$this->db->select($select);
$q = $this->db->get_where('`'.$table.'`', $where);
return ($q->num_rows() > 0) ? $q->result() : FALSE;
}
.
.
.
//bunch of another functions
in controller I just call
$this->data['books'] = $this->general_model->_getWhere('book', '*', array('active' => '1'));
$this->render('book_list_view'); // $this->load->view('book_list_view', $this->data);
sidenote: I am extending CI_Controller therefore I use $this->data['books'] instead $data['books'] to pass data into view
in view
//check if there are any data
if ($books === FALSE) {
//some error that there are no books yet
} else {
//load data to table or something
foreach ($books as $book) {
$book->id; // book id
}
}

Foreach row array CodeIgniter

I have created a model which joins 2 tables
function list_get($id){
$this->load->database();
$query = $this->db-> select('*')
->from('lists')
->join('list_items', 'list_items.items_list_id = lists.list_id')
->where('items_list_id', $id);
return $query->get()->row_array();
}
In my controller I created the view_list function
public function view_list($id = !FALSE){
$this->load->model('model_lists');
$data["query"] = $this->model_lists->list_get($id);
$this->load->model('model_lists');
if($data["query"]){
$this->load->view('lists/view_list',$data);
} else {
redirect('lists');
}
}
Now my view returns only the first result from the database
<?php echo $query['item_url'];?> How can I create a foreach to show all the results?
change this line return $query->get()->row_array();
to return $query->get()->result_array();
in view
foreach($query as $querys){
echo $querys['item_url'];
echo '</br>';
}
Change this return $query->get()->row_array(); to this
return $query->result_array();
and in view
foreach($query as $row)
{
echo $row['column_name'];
}

Codeigniter model pass value controller to view

Table products: id, product, lining, ...
Table tbl_lining: id, article, description
Model
public function getliningsale($id)
{
$this->db->select('*');
$this->db->from('products');
$this->db->join('tbl_lining', 'products.lining=tbl_lining.id', 'left');
$this->db->where('products.id', $id); // Also mention table name here
$query = $this->db->get();
if($query->num_rows() > 0)
return $data->result();
}
Controller
function liningsale($id)
{
$data['liningsale'] = $this->sales_model->getliningsale($id);
$this->load->view('add', $data);
}
View
echo '<td><input class="span1 tran2" name="lining\'+ count +\'" type="text"';
echo 'value="';
foreach ($liningsale as $valor) {
echo $valor->article;
echo '-';
echo $valor->description;
echo '">';
}
echo '</td>';
This doesn't display any record.
I've tried several ways without success.
Can anyone help?
In your model, you need to return the $query result.
At the minute you are trying to return the result set of a variable named $data which I presume doesn't exist!!
Try changing return $data->result(); to return $query->result();
Hope that helps!!

Codeigniter dropdown only retrieve last data from db

I use CI form with form_dropdown helper and tried to pull Mysql data into its options, from the below code, its only retrieve the last record from db into the option list?
please advise what is wrong with my code?
Model
public function getStates() {
$query = $this->db->get('states');
$return = array();
if($query->num_rows() > 0){
$return[''] = 'please select';
foreach($query->result_array() as $row){
$return[$row['state_id']] = $row['state_name'];
}
}
return $return;
}
Controller
$this->load->model('db_model');
$data['options'] = $this->db_model->getStates();
$this->load->view('create_new', $data);
View
$state = array(
'name' => 'state',
'id' => 'state',
//'value' => set_value('state', $state)
);
<?php echo form_label('State', $state['id']); ?>
<?php echo form_dropdown($state['name'], $options); ?>
<?php echo form_error($state['name']); ?>
<?php echo isset($errors[$state['name']])?$errors[$state['name']]:''; ?>
send full query result from the model to the view like this
Model
public function getStates() {
$query = $this->db->get('states');
return $query->result();
}
let the controller as it is and now you can populate states in dropdown like this:
View
<?php
foreach($options as $opt){
$options[$opt->state_id]=$opt->state_name;
}
echo form_dropdown($state['name'], $options);
?>
Try this:
function getStates() {
$return = array();
$query = $this->db->get('states')->result_array();
if( is_array( $query ) && count( $query ) > 0 ){
$return[''] = 'please select';
foreach($query as $row){
$return[$row['state_id']] = $row['state_name'];
}
}
return $return;
}

repopulating the select list generated from database in codeigniter

Hi. I have the form in which I use form_validation If the user make any mistake (leave some required fields empty), user is redirected back to the form, and the form has been re-populated. All works, except my select , which is generated from the database.
Here is my code from the view:
echo "<select name='parentid'" . set_value("parentid"). ">";
echo '<option value = "0">None</option>';
foreach ($faq_categories as $row => $option) {
echo "<option value=" . $option['catid'] . ">" . $option['categoryname']. "</option>";
}
echo '</select>';
Here is my controller code:
public function displayAddFaqCategoryForm($error = null)
{
$data['title'] = "Add new FAQ Category";
$data['main_content'] = 'addFaqCategory';
$selectWhat = array('tname' => 'faq_categories',
'sortby'=> 'catid',
'how' => 'asc'
);
$this->load->model('selectRecords');
$data['faq_categories'] = $this->selectRecords->selectAllRecords($selectWhat);
$this->load->vars($data);
$this->load->view('backOffice/template');
} // end of function displayAddFaqCategoryForm
And here is the model code:
public function selectAllRecords($selectWhat = array())
{
$data = array();
$tname = $selectWhat['tname'];
$sortby = $selectWhat['sortby'];
$how = $selectWhat['how'];
$this->db->order_by($sortby,$how);
$query = $this->db->get($tname);
if($query->num_rows() > 0)
{
foreach($query->result_array() as $row)
{
$data[] = $row;
}
}
$query->free_result();
return $data;
} // end of function selectAllRecords
I am not getting any error messages, just the select is not repopulated with last used. Any help will be deeply appreciated.
You're using set_value() incorrectly
echo "<select name='parentid'" . set_value("parentid"). ">";
It's meant to output the actual value (for text inputs). This would produce something like:
<select name='parentid'ActualValue>
Which is not how a <select> element is populated, and is invalid HTML. See the correct usage in the Form Helper docs.
You can use set_select(), and it goes on your <option>:
foreach ($faq_categories as $row => $option) {
echo "<option value=".form_prep($option['catid']).'"';
echo set_select('parentid', $option['catid']); // outputs selected="selected"
echo ">".html_escape($option['categoryname'])."</option>";
}
I've taken a few other liberties with your code here as you can see, to be on the safe side (always).
If this is too much of a mess, you might be interested in the form_dropdown() function.

how do i get only one question and related answer in codeigniter way?

my controller is
$data['qna'] = $this->Ivote_model->get_qa();
view
foreach($qna as $k=>$v){
echo $v['question']. '<br/>';
echo '-' .$v['answer'] . '<br/>';
model
function get_qa(){
$data = array();
$this->db->select('*');
$this->db->where('v_questions.id',1);
$this->db->from('v_answers');
$this->db->join('v_questions','v_questions.id = v_answers.question_id');
$q = $this->db->get();
if($q->num_rows > 0){
foreach($q->result_array() as $row){
$data[] = $row;
}
}
$q->free_result();
return $data;
}
my html page shows
What is your favorite food?
-Sushi
What is your favorite food?
-Burgers
What is your favorite food?
-kodo
what i want is
What is your favorite food?
-Sushi
-Burgers
-koddo
please help me how do i achieve that ?
I would do a couple of things:
function get_qa(){
/* ... */
if($q->num_rows > 0){
foreach($q->result_array() as $row){
// create an associative array of question => answer.
// that ensures 1-1 mapping.
if(!isset($data[$row['question']])) $data[$row['question']] = array();
$data[$row['question']][] = $row['answer'];
}
}
/* ... */
}
Then, in the view:
foreach($qna as $k=>$v){
echo $k. '<br/>';
foreach( $v as $ans ){
echo '-' .$ans . '<br/>';
}
}
