for example i have database :
id | Code | Name | Age |
==============================
1 | 111 | AAAA | 21 |
2 | 121 | BBBB | 23 |
and sql query code :
public function detail($Code)
{
$tSQL = "select * from table_employee where Code = '{$Code}' ";
$query = $this->db->query($tSQL);
return $query->num_rows();
}
how to display in view
<?php
if( !empty($detail) ) { foreach($detail as $row) { ?>
<?php echo "<tr>" ?> <?php echo "<td width='1%'><center>".$row->code;"<center></td>" ?>
<?php echo "<td width='1%'><center>".$row->name;"<center></td>"?>
<?php echo "<td width='1%'><center>".$row->age;"<center></td>"?>
<?php }} ?>
from condition where theres any one know?
In view you only need to use tag to your php syntax
<?php
if(!empty($detail) ) {
foreach($detail as $row) { ?>
<tr>
<td width='1%'><center><?php echo $row->code;?> <center></td>
<td width='1%'><center><?php echo $row->name;?> <center></td>
<td width='1%'><center><?php echo $row->age;?><center></td>
</tr>
<?php }} ?>
Try once..
Controller..
public function detail($Code)
{
$this->db->where('Code',$Code);
$data = $this->db->get('table_employee')->result();
return $data;
}
In view
foreach($data as $row) { ?>
<tr>
<td width='1%'><center><?php echo $row->code;?> <center></td>
<td width='1%'><center><?php echo $row->name;?> <center></td>
<td width='1%'><center><?php echo $row->age;?><center></td>
</tr>
<?php } ?>

I am trying to get the selected from a drop down menu. but it returns the index of the selected elements. I want to retrieve the value of that index. I want to get the value of $year. how can I get the value?
Controller that generate the years
<?php
class StockReportConditionsController extends AppController{
public function report() {
$years = array();
for ($i = 0; $i < 4; $i++) {
$year = date("Y");
$year = $year -$i;
$years[$i]=$year;
}
$this->set(compact('years'));
}
View
<h1>Weekly Report</h1>
<table>
<tr>
<th>Year</th>
<th>Stores</th>
<th>Department</th>
</tr>
<?php echo $this->Form->create('StockReport',array('url'=>array('type' => 'get','action'=>'search')));?>
<tr>
<td>
<?php echo $this->Form->input('year',array('type'=>'select','options'=>$years)); ?>
</td>
<td>
<?php echo $this->Form->input('Store.name',array('type'=>'select','options'=>$stores)); ?>
</td>
<td>
<?php echo $this->Form->input('StockReportCondition.bu_no',array('type'=>'select','options'=>$departments)); ?>
</td>
</tr>
<?php echo $this->Form->end(__('Search'));?>
</table>
Controller
<?php
class StockReportsController extends AppController{
public function search(){
$year = $this->request->data['StockReport']['year'];
echo $year;
$store_no = $this->request->data['Store']['name'];
echo $store_no;
$dept_no = $this->request->data['StockReportCondition']['bu_no'];
echo $dept_no;
$result = $this->StockReport->find('all',array(
'conditions'=>array('yearweek'=>'', 'bu_no'=>'','tn_no'=>'')
));
}
}
It would seem that there's probably never a useful thing that you could do with the zero-based index of the year, and you'd only ever want the actual year value. If that's the case, then set up your options array so that the index and value are the same:
$years[$year]=$year;
How can i get Hierarchical Data from db in Codeigniter. I read this :
http://www.sitepoint.com/hierarchical-data-database/
And i do good that but i cant optimize this tutorial with my model, controler and views
Default Category
|----- Sub category
| ----One more category
|----- Somthing else
I try but dont show sub category:
My model:
public function fetchChildren($parent, $level) {
$this->handler = $this->db->query("SELECT * FROM content_categories WHERE parent_id='".$parent."' ");
foreach($this->handler->result() as $row ) {
$this->data[$row->id] = $row;
//echo str_repeat(' ',$level).$row['title']."\n";
}
return $this->data;
}
Controller :
$this->data['node'] = $this->categories_model->fetchChildren(' ',0);
Views:
<table class="module_table">
<thead>
<tr>
<th><?php echo lang('categories_table_title'); ?></th>
</tr>
</thead>
<tbody>
<?php foreach ($node as $row) : ?>
<tr>
<th> <?php echo str_repeat('|----', 0+1). $row->title ?> </th>
</tr>
<?php endforeach; ?>
</tbody>
</table>
And output is :
----Default
----Default
----Test Category 1
----Seccond Test Category 1
----Another Test Category 1
When i do this in model all work fine but when i try that to call in controler and loop in view i have result like above example:
This work onlu in model:
public function fetchChildren($parent, $level) {
$this->handler = $this->db->query("SELECT * FROM content_categories WHERE parent_id='".$parent."' ");
foreach($this->handler->result() as $row ) {
echo str_repeat('|-----',$level).$row->title."\n";
$this->fetchChildren($row->title, $level+1);
}
return $this->data;
}
And like output i have :
Default
|----Test Category 1
|----Seccond Test Category 1
|----Another Test Category 1
Any one have solution or example thanks.
Try storing the level value for each category.
In your model:
public function fetchChildren($parent, $level){
$this->handler = $this->db->query("SELECT * FROM content_categories WHERE parent_id='".$parent."' ");
foreach($this->handler->result() as $row ) {
$row->level = $level;
$this->data[] = $row;
$this->fetchChildren($row->title, $level+1);
}
return $this->data;
}
In your controller:
$this->data['node'] = $this->categories_model->fetchChildren(' ',0);
In your view
<table class="module_table">
<thead>
<tr>
<th><?php echo lang('categories_table_title'); ?></th>
</tr>
</thead>
<tbody>
<?php foreach ($node as $row) : ?>
<tr>
<th><?php echo str_repeat('|----', $row->level). $row->title ?> </th>
</tr>
<?php endforeach; ?>
</tbody>
</table>
I have use two query to get result on the view.
To get the result of resultq1 i use foreach but how can i get result of resultq2 in view.
For each row of resultq1 i get record "reccount" in resultq2.
//controller
//Query 1
$q = $this->db->select(array(
'spf.id as id' ,
'spf.name',
"if(u.username != '',u.username,spf.added_by) as added_by ",
'spf.added_on'
))->from('sp_forum spf')->join('sp_users u', 'spf.added_by = u.id', 'left')->where($where)->order_by('spf.id desc')->limit(10, $page * 10)->get();
$resultq1= $q->result_array();
$data['resultq1'] = $resultq1;
$resultq2 = array();
$i=0;
foreach($resultq1 as $rec)
{
//query 2
$id = $rec['id'];
$q1 = $this->db->select("count('id') as reccount ")->from('sp_forum_topic spft')->where('spft.forumid',$id)->get();
$resultq2[$i] = $q1->row_object();
$i++;
}
$this->load->view('forumview', $data, true);
//view file
<table width="100%">
<tr>
<td class="th"> Details</td>
<td width="5%" class="th"> Answer</td>
<td width="15%" class="th">Started by</td>
<td width="15%" class="th">Created on</td>
</tr>
<?php foreach($resultq1 as $row):?>
<tr>
<td><?php echo $row['name'] ;?></td>
<td >---- </td> // here i want to use resultq2
<td><?php echo $row['added_by'] ;?></td>
<td ><?php echo $row['added_on'];?></td>
</tr>
<?php endforeach;?>
</table>
Array print in view for resultq2.
Resultq1 have 4 rows so that i get 4 value in resultq2.
Array ( [0] => stdClass Object ( [reccount] => 0 ) [1] => stdClass Object ( [reccount] => 0 ) [2] => stdClass Object ( [reccount] => 0 ) [3] => stdClass Object ( [reccount] => 2 ) ) 0002
You need to pass $resultq2 to the view as well.
In the controller, just before calling the view
$data['resultq2'] = $resultq2
You can now use $resultq2 in your view.
PS - SQL queries should be in models, not controllers.
Just Write '$data['resultq2'] = $resultq2' before loading the view,
$data['resultq2'] = $resultq2
$this->load->view('forumview', $data, true);
And you can retrieve it in the view by $result2 variable.
Just do var_dump($result2); in your view file, You will get the complete data of $result2 varaible.
And xbonez is right, do write your DB queries in the model, controller is only for login, and coordinating between (models, views, libraries, helper etc...)
I optimized your second query a bit, but logic is pretty much the same.
$q = $this->db->select(array(
'spf.id as id' ,
'spf.name',
"if(u.username != '',u.username,spf.added_by) as added_by ",
'spf.added_on'
))->from('sp_forum spf')->join('sp_users u', 'spf.added_by = u.id', 'left')->where($where)->order_by('spf.id desc')->limit(10, $page * 10)->get();
$resultq1= $q->result_array();
$data['resultq1'] = $resultq1;
$ids = array();
foreach($resultq1 as $result)
$ids[] = $result['id'];
$resultq2 = $this->db->select("count('id') as reccount ")->from('sp_forum_topic spft')->where_in('spft.forumid',$ids)->get();
foreach( $resultq2->result_array() as $res )
$newArr[$res['forumid']] = $res;
$data['resultq2'] = $newArr;
After resultq2 is indexed by original id, its easy to use id from resultq1 loop to show correct data
<table width="100%">
<tr>
<td class="th"> Details</td>
<td width="5%" class="th"> Answer</td>
<td width="15%" class="th">Started by</td>
<td width="15%" class="th">Created on</td>
</tr>
<?php foreach($resultq1 as $row):?>
<tr>
<td><?php echo $row['name'] ;?></td>
<td >
<?php
print_r( $resultq2[$row['id']]);
?>
</td> // here i want to use resultq2
<td><?php echo $row['added_by'] ;?></td>
<td ><?php echo $row['added_on'];?></td>
</tr>
<?php endforeach;?>
</table>
This should fix it.
Modify the controller - see comments also
<?php
//Query 1
$q = $this->db->select(array(
'spf.id as id',
'spf.name',
"if(u.username != '',u.username,spf.added_by) as added_by ",
'spf.added_on'
))->from('sp_forum spf')->join('sp_users u', 'spf.added_by = u.id', 'left')->where($where)->order_by('spf.id desc')->limit(10, $page * 10)->get();
$resultq1 = $q->result_array();
$data['resultq1'] = $resultq1;
$resultq2 = array();
foreach ($resultq1 as $rec) {
//query 2
//echo $id = $rec['id']; //Test and See if all IDs echo out correctly
$data["id"] = $id; //Add this for the ID
$q1 = $this->db->select("count('id') as reccount, spft.forumid")->from('sp_forum_topic spft')->where('spft.forumid', $id)->get();
$resultq2[$id] = $q1->result(); //Change this line
$data["resultq2"][$id] = $resultq2[$id]; //Add this line
}
//echo "<pre>";
//$export = var_export($data, true);// Test the returned value...
//echo "</pre>";
$this->load->view('forumview', $data, true);
?>
In Your view
<table width="100%">
<tr>
<td class="th"> Details</td>
<td width="5%" class="th"> Answer</td>
<td width="15%" class="th">Started by</td>
<td width="15%" class="th">Created on</td>
</tr>
<?php //foreach ($resultq1 as $row): ?>
<?php foreach ($data as $row): ?>
<tr>
<td><?php echo $row['name']; ?></td>
<td>
<?php
//$resultq2 is now array
//print_r($resultq2); //Do this so you can see the depth of the array
foreach ($resultq2 as $counts) {
foreach ($counts as $count) { //The second foreach might be necessary - please test
echo $count->reccount; //This should print out the count result
//echo "<br />";
}
}
?>
</td>
<td><?php echo $row['added_by']; ?></td>
<td ><?php echo $row['added_on']; ?></td>
<td >
</td>
</tr>
<?php
endforeach;
exit;
?>
</table>
I haven't had time to test it but it should work. Let me know if you find any issues:
i've just started learning Jplugin development, so here i made a little voting script. Everything here works fine, but i want conf.php file to be made in joomla framework style. As you see here, 1 and 2 files works perfectly together. I want to use third example instead of second, in which i use simple php code. The last example i tried to do is using joomla framework, but it doesnt work. I have no idea what's wrong with that code. Anyone see could tell where I made a mistake or maybe far away from doing it right ?

I am trying to display information from database. I have set $config['per_page'] to 2, in my view file I can see the information I want but when I click on the next button it doesn't change anything. The database values remain same and the current page remains the first page too.
Would you please kindly help me figure out the problem?
Thanks in Advance :)

You are telling the pagination library to use $config['uri_segment'] = '2'; - the second segment of your uri.
When this is your url: http://localhost/sundial/Student_fee_status/index/1006/ I am guessing this is your base_url: http://localhost/sundial/
In this case your segments are:
Student_fee_status - your controller
index - the controllers method you are calling
1006 - the argument you are calling the controllers method with
this should be the argument for pagination
Try this
$config['uri_segment'] = '4';
instead of
$config['uri_segment'] = '2';
edit:
$data['records']= $this->Mod_student_fee_status->fee_status($id,$config['per_page'],$config['uri_segment']);
I think this line contains another error.
You pass your model the information which uri_segment is used by the pagination library. That should be 4 now. However, your model uses this value to specify an offset in your query. This means you always put an offset of 4 into your query. But I think what you really want to do is, pass the model the VALUE of the 4th uri_segment.
I would try this instead:
$data['records']= $this->Mod_student_fee_status->fee_status($id,$config['per_page'],$this->uri->segment($config['uri_segment']));
