i tried to use print_r($list) but the result array().There is no element in the array.I want to show data form my table.there is user table, job table and industry table.Can anybody suggest me where is mistake.
This is my model function get_data_by_query used in controller
public function get_data_by_query($qry)
{
$query = $this->db->query($qry);
return $query->result();
}
This is my controller where i am verifying email, phone number.
public function Dashboard()
{
if ($this->Common_model->Is_User_Logged())
{
$condition='';
$data['email_verified']=self::IsEmailVerified();
$data['phone_verified']=self::IsPhoneVerified();
$userdata=$this->session->userdata('user_logged_in');
$data['user_email']=$userdata['email'];
//print_r($data);
$res=$this->Common_model->get_data_by_query("SELECT * FROM user WHERE user_id={$userdata['id']} limit 1");
//print_r($res);
$data['user_skills'] = $res[0]->user_skills;
//print_r($data);
$arr = array($res[0]->user_skills);
//print_r($arr[0]);
//exit;
$condition.=" and FIND_IN_SET(job_title,'$arr[0]')";
print_r($condition);
$sql_get="SELECT j.*,j.job_industry,i.industry_title
FROM job j
LEFT JOIN industry i on i.industry_id=j.job_industry
WHERE job_status=1 ".$condition." ";
//print_r($sql_get);
$data['list']=$this->Common_model->get_data_by_query($sql_get);
//print_r($data['list']);
$data['user_phone']=$res[0]->user_mobile;
$this->load->view('user/header');
$this->load->view('user/home', $data);
$this->load->view('user/footer');
}
else
{
redirect('user');
}
}
This is my view
<?php
if(!empty($list)>0)
{
foreach ($list as $row)
{
?>
<tr>
<td><?php echo $row->job_role;?></td>
<td><?php echo $row->industry_title;?></td>
<td><?php echo $row->job_vacancy;?></td>
<td><?php echo $row->job_keyword;?></td>
<!--<td><?php echo $row->job_type;?></td>-->
</tr>
<?php
} }
?>
what is the reason that $list is empty array although i have data in my table. I will be thankful for you.
After a lot of effort, i found that there is no problem in above code. The problem is in tje SQL query. I am trying to resolve that query.
I'm trying to get all results from my database. I have an OOP structure set up and created a couple functions in my DB class which get all results from the database.
public function getAll($table, $order) {
return $this->actionAll('SELECT *', $table, $order);
}
public function actionAll($action, $table, $order) {
$sql = "{$action} FROM {$table} ORDER BY {$order} DESC";
if(!$this->queryAll($sql)) {
return $this;
}
}
public function queryAll($sql) {
$this->_error = false;
if($this->_query = $this->_pdo->prepare($sql)) {
if($this->_query->execute()) {
$this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ);
$this->_count = $this->_query->rowCount();
} else {
$this->_error = true;
}
}
}
In my Page class I'm calling the functions from my DB class and counting the results.
public function get() {
$data = $this->_db->getAll('pages', 'created');
if($data->count()) {
$this->_data = $data->first();
return true;
}
}
Next, in my list PHP file I'm calling the get function from my Page class and creating an foreach loop to loop through the results.
<?php $page = new Page();
$pages = $page->get();
if(empty($pages)): ?>
<p>No pages at the moment</p>
<?php else: ?>
<?php foreach($pages as $item): ?>
<tr>
<td><?php echo e($item->data()->label); ?></td>
<td><?php echo e($item->data()->title); ?></td>
<td><?php echo e($item->data()->slug); ?></td>
<td>Edit</td>
<td>Delete</td>
</tr>
<?php endforeach;
endif; ?>
The problem is that I'm getting the error Invalid argument supplied for foreach(). I don't really understand why I'm getting this error.
I've tried to fix this, but couldn't think of a solution.
Instead of checking empty($pages) check !is_array($pages).
<?php $page = new Page();
$pages = $page->get();
if(!is_array($pages)): ?>
<p>No pages at the moment</p>
<?php else: ?>
<?php foreach($pages as $item): ?>
<tr>
<td><?php echo e($item->data()->label); ?></td>
<td><?php echo e($item->data()->title); ?></td>
<td><?php echo e($item->data()->slug); ?></td>
<td>Edit</td>
<td>Delete</td>
</tr>
<?php endforeach;
endif; ?>
I want to validate and insert multiple records from single form.
I tried following solution, but it is not validating each records.
Yii - multiple records in one form submission
I've used something like this in my form:
<td><?php echo CHtml::activeTextField($item,"[$i]name"); ?></td>
<td><?php echo CHtml::activeTextField($item,"[$i]price"); ?></td>
<td><?php echo CHtml::activeTextField($item,"[$i]count"); ?></td>
<td><?php echo CHtml::activeTextArea($item,"[$i]description"); ?></td>
And in my controller I've done similar to this:
public function actionBatchCreate() {
$models=array();
// since you know how many models
$i=0;
while($i<5) {
$models[]=Modelname::model();
// you can also allocate memory for the model with `new Modelname` instead
// of assigning the static model
}
if (isset($_POST['Modelname'])) {
$valid=true;
foreach ($_POST['Modelname'] as $j=>$model) {
if (isset($_POST['Modelname'][$j])) {
$models[$j]=new Modelname; // if you had static model only
$models[$j]->attributes=$model;
$valid=$models[$j]->validate() && $valid;
}
}
if ($valid) {
$i=0;
while (isset($models[$i])) {
$models[$i++]->save(false);// models have already been validated
}
// anything else that you want to do, for example a redirect to admin page
$this->redirect(array('modelname/admin'));
}
}
$this->render('batch-create-form',array('models'=>$models));
}
<?php
public function actionBatchCreate()
{
$arrItems = array();
$valid = true;
if(isset($_POST['Modelname'])) {
foreach ($_POST['Modelname'] as $i => $notUsed)
{
$objItem = new Modelname();
$objItem->attributes=$_POST['Modelname'][$i];
$valid = $objItem->validate() && $valid;
$arrItems[] = $objItem;
}
if($valid) {
foreach ($arrItems as $objItemValidated) {
$objItemValidated->save();
}
$this->redirect(array('modelname/admin'));
}
}
// optional create a initial empty row in View
if(!count($arrItems)) {
$arrItems[] = new Modelname();
}
$this->render('batch-create-form',array('models'=>$arrItems));
}
View-File batch-create-form.php
<table>
<?php foreach($models AS $i => $item):?>
<tr>
<td><?php echo CHtml::activeTextField($item,"[$i]name"); ?></td>
<td><?php echo CHtml::activeTextField($item,"[$i]price"); ?></td>
<td><?php echo CHtml::activeTextField($item,"[$i]count"); ?></td>
<td><?php echo CHtml::activeTextArea($item,"[$i]description"); ?></td>

Hello all I have a problem that my information is not being send to my view file.
What mistake do I have?
My Model:
public function viewbds($duanid, $bdsid)
{
$q = $this->db->query("SELECT bds.tenduan, bds.id, bds.tieude FROM bds WHERE bds.tenduan=$duanid AND bds.id=$bdsid);
if($q->num_rows() > 0)
return $q->result();
return false;
}
My Controller:
public function chothue($duanid, $bdsid)
{
$this->load->model('admin_model');
$date[chothue] = $this->admin_model->viewbds('$duanid', '$bdsid');
$this->load->view('admin/view', $data);
}
My View: admin/chothue/1/1
<?php foreach($chothue as $d) { ?>
<tr>
<td><?php echo $d->id; ?></td>
<td><?php echo $d->tenduan; ?></td>
<td><?php echo $d->tieude; ?></td>
<?php } ?>
$this->db->query("SELECT bds.tenduan, bds.id, bds.tieude FROM bds WHERE bds.tenduan=$duanid AND bds.id=$bdsid")->get();
Don't forget to use ->get()
AND use active record
$this->db->select("tenduan, id, tieude")->from("bds")->where("tenduan", $duanid)->where("id", $bdsid)->get();
Here is my model - I want to assign the rows and echo out on the view page e.g
My Model:
public function dsduan(){
$data = array();
$q = $this->db->query("SELECT duan.id, duan.tenduan, duan.diachi, quan.quan, duan.tdt, duan.mdxd, duan.tt, duan.cdt, duan.dvql, duan.dvtk, duan.dvtc, duan.dvgs, duan.loai, duan.tienich, duan.noidung, duan.hinhanh FROM duan LEFT JOIN quan ON duan.quan=quan.id ORDER BY duan.tenduan ASC");
if ($q->num_rows == 1)
{
foreach ($q->result() as $row)
{
$data[]['id'] = $row->id;
$data[]['tenduan'] = $row->tenduan;
$data[]['diachi'] = $row->diachi;
$data[]['quan'] = $row->quan;
}
}
return $data;
}
My Controller:
public function dsduan() {
$this->load->model('madmin');
$duan = $this->madmin->dsduan();
$this->load->view('danhsachduan', $duan);
}
My View:
<td><?php echo $id; ?></td>
<td><?php echo $tenduan; ?></td>
<td><?php echo $diachi; ?></td>
<td><?php echo $quan; ?></td>
How do I properly pass my model array to my controller so that I can echo out on my view?
My view Error:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: id
Filename: views/danhsachduan.php
Line Number: 44
In your model you use two dimensional array:
$data[]['id'] = $row->id;
then in your controller you pass this array to view.
so if you want to access two dimensional array into your view, you have to use foreach loop.
such as change your array in model like following:
$data['id'][] = $row->id;
and in your view access array using:
foreach($id as $res)
{
echo $res;
}
update your view like this
<?php foreach($duan as $d) { ?>
<td><?php echo $d['id']; ?></td>
<td><?php echo $d['tenduan']; ?></td>
<td><?php echo $d['diachi']; ?></td>
<td><?php echo $d['quan']; ?></td>
<?php } ?>
public function dsduan(){
$data = array();
$q = $this->db->query("SELECT duan.id, duan.tenduan, duan.diachi, quan.quan, duan.tdt, duan.mdxd, duan.tt, duan.cdt, duan.dvql, duan.dvtk, duan.dvtc, duan.dvgs, duan.loai, duan.tienich, duan.noidung, duan.hinhanh FROM duan LEFT JOIN quan ON duan.quan=quan.id ORDER BY duan.tenduan ASC");
if ($q->num_rows == 1)
{
foreach ($q->result() as $row)
{
$data['id'] = $row->id;
$data['tenduan'] = $row->tenduan;
$data['diachi'] = $row->diachi;
$data['quan'] = $row->quan;
}
}
return $data;
}
In codeigniter, it use extract() method when binding variable from controller to view. In this case, you can do like this.
In Model
public function dsduan()
{
$data = array();
$q = $this->db->query("SELECT duan.id, duan.tenduan, duan.diachi, quan.quan, duan.tdt, duan.mdxd, duan.tt, duan.cdt, duan.dvql, duan.dvtk, duan.dvtc, duan.dvgs, duan.loai, duan.tienich, duan.noidung, duan.hinhanh FROM duan LEFT JOIN quan ON duan.quan=quan.id ORDER BY duan.tenduan ASC");
if ($q->num_rows)
{
$data = $q->result_array();
}
return $data;
}
In Controller
public function dsduan()
{
$this->load->model('madmin');
$data['duan'] = $this->madmin->dsduan();
$this->load->view('danhsachduan', $data);
}
In View, if your array is multi-dimensional, you can use like this,
<?php foreach($duan as $d) { ?>
<td><?php echo $d['id']; ?></td>
<td><?php echo $d['tenduan']; ?></td>
<td><?php echo $d['diachi']; ?></td>
<td><?php echo $d['quan']; ?></td>
<?php } ?>
if your array is one-dimensional, you can use like this,
<td><?php echo $duan['id']; ?></td>
<td><?php echo $duan['tenduan']; ?></td>
<td><?php echo $duan['diachi']; ?></td>
<td><?php echo $duan['quan']; ?></td>
Have modified your code. Kindly replace below with your code.
Model:
public function dsduan()
{
$q = $this->db->query("SELECT duan.id, duan.tenduan, duan.diachi, quan.quan, duan.tdt, duan.mdxd, duan.tt, duan.cdt, duan.dvql, duan.dvtk, duan.dvtc, duan.dvgs, duan.loai, duan.tienich, duan.noidung, duan.hinhanh FROM duan LEFT JOIN quan ON duan.quan=quan.id ORDER BY duan.tenduan ASC");
if($q->num_rows() > 0)
return $q->result();
return false;
}
Controller:
public function dsduan()
{
$this->load->model('madmin');
$data['duan'] = $this->madmin->dsduan();
$this->load->view('danhsachduan', $data);
}
View:
<?php foreach($duan as $d) { ?>
<td><?php echo $d->id; ?></td>
<td><?php echo $d->tenduan; ?></td>
<td><?php echo $d->diachi; ?></td>
<td><?php echo $d->quan; ?></td>
<?php } ?>
