some body helpme. i have same error like that
"Message: Array to string conversion
Filename: helpers/form_helper.php
Line Number: 325"
this is my model, controller, and view code
function get_data()
{
$query = $this->db->get('
if ($query->num_rows() >
{
return $query->row_array();
}else{
return FALSE;
}
//controller
{ $data['title'] = "project"; $data['main_content'] =
'jurnal_proyek/display'; $this->jurnal_model->set_project();
$data['journal_data'] = $this->jurnal_model->get_data();
$this->load->view('layout/template', $data); }
//view
'Semua', 4 => 'Pendapatan',5 => 'Biaya'); echo form_dropdown('jenis', $options, $selected, $data);
?>
the formatting was quite bad on your post. I could not follow it well..
read the documentation carefully. you have 4 parameters; the first is the name, second is an associative array of value/option pairs, third is selected item, fourth is a string of text to be inserted in the select box.
instead of :
echo form_dropdown('jenis', $options, $selected, $data);
try something like:
echo form_dropdown('jenis', $journal_data, $selected);

my controller is
function shiftstudentdetailsmultiple(){
$data['Show'] = $this->input->post('show[]');
$roll = $this->input->post('roll[]');
//echo sizeof($data1);
for($i=0;$i<sizeof($roll);$i++)
{
$data['results'] = $this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
}
$this->load->view('registrar/shift_student_view', $data);
}
and model is
function getstudentsdetailscouseandmultiple($Uniq_Id){
$this->db->select("sprd.Uniq_Id, sprd.Name, sprd.Uni_Roll_No, cd.Course_Name, bd.Branch_Name, sprd.Year, sprd.Session, sprd.Section, sprd.Fee_Status, sprd.Curr_Status");
$this->db->where("sprd.Uniq_Id",$Uniq_Id);
$this->db->from("Students_Prim_Detals sprd");
$this->db->join('Course_Details cd', 'cd.Course_Id=sprd.Course_id');
$this->db->join('Branch_Details bd', 'bd.Branch_Id=sprd.Branch_id');
$query = $this->db->get();
if ($query->num_rows() > 0){
return $query->result();
}
else {
return false;
}
}
when showing in view the fetching data showing only one time.. but in my database i have more then 4 entry when i print_r
$data['results']=this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
the data showing correct .. when load only showing one data..the last entry..
$this->load->view('registrar/shift_student_view', $data);
Each time you call...
$data['results'] = $this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
you replace the value stored in $data['results'] with the new return. So only one return is sent to the view.
You will need to revise your controller along these lines.
$student_detail = array();
for($i=0;$i<sizeof($roll);$i++)
{
$student_detail[] = $this->FetchData->getstudentsdetailscouseandmultiple($roll[$i]);
}
$data['results'] = $student_detail;
Then in your view you will have to loop through $results to display each item in the array.
foreach($results as $detail){
echo "Name: ". $detail->name;
echo "Course: ". $detail->Course_Name;
//etc...
}
My model:
function get_data($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) {
$book->id; // book id
}
}
Im trying to get joins to work when selecting a single row. here is my code:
model:
function view($id) {
$this->db->select('c.name
,c.phone
,c.active
,c.website
,c.date_acquired
,con.firstName');
$this->db->from('company c');
$this->db->join('contacts con','c.primary_contact = con.id','left');
$this->db->where('id', $id);
$query = $this->db->get();
return $query->row_array();
controller:
public function view($id)
{
$this->load->model('Company_model');
$data['data']= $this->Company_model->view($id);
$this->load->view('templates/header');
$this->load->view('company/view', $data);
$this->load->view('templates/footer');
}
the error im getting is:
Fatal error: Call to a member function row_array() on a non-object in
/home/techf/public_html/application/models/company_model.php on line
35
and line 35 in the above code is:
$query = $this->db->get()
is this not correct when dealing with joins and a row array?
**
edit 1
**:
Here is my controller:
public function view($id)
{
$this->load->model('Company_model');
$data = $this->Company_model->view($id)->row();
$this->load->view('templates/header');
$this->load->view('company/view', $data);
$this->load->view('templates/footer');
}
and my model:
function view($id) {
$this->db->select('*');
$this->db->from('company');
$this->db->join('contacts con','c.primary_contact = con.id','left');
$this->db->where('id', $id);
return $this->db->get('company');
}
but now im am getting error:
Fatal error: Call to a member function row() on a non-object in
/home/techf/public_html/application/controllers/company.php on line 21
Here you go model code
public function get_joins($table,$value,$joins,$where,$order_by,$order)
{
$this->db->select($value);
if (is_array($joins) && count($joins) > 0)
{
foreach($joins as $k => $v)
{
$this->db->join($v['table'], $v['condition'], $v['jointype']);
}
}
$this->db->order_by($order_by,$order);
$this->db->where($where);
return $this->db->get($table);
}
and in your controller aceess it like
$value=('restaurantorders.*,restaurant.Name,restaurant.CurrencyId,currency.*,orderpaymentdetail.Gateway ');
$joins = array
(
array
(
'table' => 'tk_restaurant',
'condition' => 'restaurant.Id = restaurantorders.RestaurantId',
'jointype' => 'inner'
),
array
(
'table' => 'tk_currency',
'condition' => 'restaurant.CurrencyId = currency.Id',
'jointype' => 'inner'
),
array
(
'table' => 'tk_orderpaymentdetail',
'condition' => 'restaurantorders.Id = orderpaymentdetail.OrderId',
'jointype' => 'inner'
),
);
$data['order_detail'] = $this->general_model->get_joins($data['tbl'],$value,$joins,array('OrderStatus'=>'Confirm','restaurantorders.Id'=>$orderid),'restaurantorders.Id','desc')->row();
note that on the model i test first if num_rows() is greater than 1 before sending on the row and if not return false.
Note that on my this->db->get i removed the name of the table, because you already added it on the from method.
$this->db->select('*')
->from('company c');
->join('contacts con','c.primary_contact = con.id','left');
->where('id', $id);
$query = $this->db->get();
return $query->num_rows() >= 1 ? $query->row() : FALSE;
on your COntroller
on on the data variable you forgot to add a key, this will be used when you access the variable/object on you're view, example is $data['contacts']
public function view($id)
{
$this->load->model('Company_model');
$data['contacts'] = $this->Company_model->view($id);
$this->load->view('templates/header');
$this->load->view('company/view', $data);
$this->load->view('templates/footer');
}
on your VIEWS
access the contacts key that you assigned earlier on you're controller.
<?
if(!empty($contacts))
{
print_r($contacts);
}else{
echo 'No data';
}
?>
to show the structure of your query on a standard MySQL query
you could comment out the return on you're model and add this snippets of code just after the $this->db->get() method.
echo $this->db->last_query();
die();
This will echo out what query was made, and you can run it on phpmyadmin and compare if the values returned are right.
can you try it like this maybe?
model: (i'm not sure in which table is id and in which primary_contact, so change that if i made a mistake)
function view($id) {
$this->db->join('contacts','company.primary_contact = contacts.id','left')
->where('id', $id);
$query = $this->db->get('company');
return $query->row();
}
in controller call it like this:
$data['result'] = $this->company_model->view($id);
then access object in view:
<?=$result->id?> (etc.)
Hi. I have the form in which I use form_validation If the user make any mistake (leave some required fields empty), user is redirected back to the form, and the form has been re-populated. All works, except my select , which is generated from the database.
Here is my code from the view:
echo "<select name='parentid'" . set_value("parentid"). ">";
echo '<option value = "0">None</option>';
foreach ($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.
I have a edit view whose url is /group/edit/1 where 1 is the group id which is dynamic.
I am validating the form data in controller as :
if ($this->form_validation->run() == FALSE)
{
$this->load->view('group/edit', $data);
}
How do I pass the id parameter "1" to this view ?
Below option does not work since the url has to be group/edit/1
$this->load->view('edit', $data);
You're thinking about this wrong. You want to have a view called edit.php and pass the number 1 into it, or perhaps more to the point, you want to get the data for 1 from your model and pass the return value of your model into your view. Consider this:
controller
function edit($id)
{
$data['item_info'] = $this->whateverModel->getItem($id);
$this->load->view('edit', $data);
}
Then in your edit view, you can refer to the data like this:
view
echo $item_info['id'];
echo $item_info['name']; //or whatever you pass back from the model
Is this what you mean?
$this->load->view('group/edit/'.$parameter, $data);
That would make it load your 1, as you are simply defining the path of the VIEW document
Per CodeIgniters reference this is the format:
$this->load->view('folder_name/file_name');
http://codeigniter.com/user_guide/general/views.html
Not sure if you are confused by routing vs views, here is a quick difference:
If you want http://www.example/group/edit/10
then you need a route setup, not a view.
If you want http://www.example/ and to display the contents from page main.php (in your views folder) then you do $this->load->view('main'); inside your primary controller.
This is what I am doing. Is this acceptable ?
