public function adduser()
{
$this->load->model('User', 'user');
$this->user->adduser();
$data = array('message' => 'Thanks for signing up');
$this->load->view('register', $data);
}
This is my function and it executes perfectly and gives a message of thanks to the register view page. But when I am loading the register view page initially, it gives me an error.
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: message
Filename: views/register.php
Line Number: 15
if anyone can help where it is going wrong.
Regard to the comment section mentioned workaround is
<?php echo ((isset($message)) ? $message : '');?>
Please see ternary operator.

I've moved from PHP5 to PHP7.
The following code no longer works.
<?php
class sandbox {
function doit() {
$method = array('name' => 'testresponse');
return $this->$method['name']();
}
function testresponse(){
return "Hi!";
}
}
$h = new sandbox();
echo "Hello, " . $h->doit();
I'm wondering what is the new syntax for this?
Here are the PHP errors I'm getting
A PHP Error was encountered Severity: Notice

Message: Array to string conversion

And
Fatal error: Uncaught Error: Function name must be a string in /var/www/application/controller/sandbox.php:20 Stack trace: #0
Change this
return $this->$method['name']();
to this
return $this->{$method['name']}();

This is my edit controller
function editpost($postID){
$data['success']=0;
if($_POST){
$data_post=array(
'title'=>$_POST['title'],
'post'=>$_POST['post'],
'active'=>1
);
$this->post->update_post($postID,$data_post);
$data['success']=1;
}
$data['post']=$this->post->get_post($postID);
$this->load->view('edit_post',$data);
}
this is my update model
function update_post($postID,$data){
$this->where('postID',$postID);
$this->db->update('posts',$data);
}
I changed the data_post - data same error
Where is my error?
put $this->db->where('postID',$postID);
$this->db->update('posts',$data) in your model code
Follow bellow code:
function update_post($postID,$data){
$this->db->where('postID',$postID);
$this->db->update('posts',$data);
}
Please change your update_post function code from $this->where('postID',$postID);
to $this->db->where('postID',$postID);. You missing ->db before ->where condition in your model page.
Thanks
I'm trying to join my table and it's working but I don't know why I got the following error messages.
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: get
Filename: views/tambah_wali.php
Line Number: 13
Fatal error: Call to a member function result() on a non-object in C:\xampp\htdocs\ujikom_sekolah\application\views\tambah_wali.php on line 13
This is my controller:
public function tambah_wali($kode){
$data['get']=$this->madm->join_wali_siswa($kode);
$this->load->view('tambah_wali');
}
This is my model:
public function join_wali_siswa($kode) {
$this->db->select('wali_murid.nisn');
$this->db->from('siswa');
$this->db->join('wali_murid','siswa.nisn=wali_murid.nisn','right');
$this->db->where('siswa.nisn',$kode);
$query=$ambildata=$this->db->get();
if($ambildata->num_rows > 0)
return $query;
else
return null;
}
This is line 13 on my view:
<?php foreach($get->result() as $row): ?>
Load your $data['get'] in your view seems to be missing when have a $data variable must add it to view like below.
$data['get'] = $this->madm->join_wali_siswa($kode);
$this->load->view('tambah_wali', $data);
For some reason i cant get my model to work.. never had this problem before.
function overview($userid)
{
// Load needed model
$this->load->model('budget_model');
$data['month_budget'] = $this->budget_model->get_monthly_budget($userid);
if(isset($_POST['submit']))
{
foreach($_POST as $key => $value)
{
if(is_numeric($key))
{
$this->buget_model->update_buget($key,$value);
echo "DONE";
}
}
echo "<pre>";
print_r($_POST);
echo "</pre>";
}
$data['main'] = 'super_admin/budget_edit_overview_view';
$this->load->view('default/main_view',$data);
}
The model works fine with "$this->budget_model->get_monthly_budget($userid);" but i keep getting thir error,
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Admin::$buget_model

The model method,
function update_buget($id,$budget)
{
$this->db->where('id', $id);
// Update the month budget
$data = array(
'month_goal' => $budget
);
$this->db->update('budget_month', $data);
return true;
}
Read the error message carefully:
Message: Undefined property: Admin::$buget_model
Did you make a typo and actually mean $budget_model?
edit: There seems to be a lot of budget vs. buget in your code. I suggest a spellchecker.
You have made a typing error in line 166.
It is $this->budget_model->update_buget($key,$value);
not $this->buget_model->update_buget($key,$value);
I'd like to use stdClass to store options for some methods, instead of passing huge lists of variables (inspired by javascript-style coding)
However, I'd like to make sure I'm always getting an instance of stdClass as an argument. I know I can add a hint in the argument (gb::search below) but when I deliberately try to break it, I'm not sure how to handle the error.
Any tips?
class gb extends CI_Model {
protected $searchtypes = array('full','partial');
protected $endpoint = "https://local.endpoint";
function __construct() {
parent::__construct();
// sample search
$options = new stdClass();
$options->term = 'sample search';
$options->type = 'full';
$this->search($options);
}
function clean_term($term){
$term = trim($term);
return $term;
}
function search(stdClass $options){
$term = $options->term;
$type = $options->type;
// make sure we're doing a valid search
if (!$term || !in_array($type, $this->searchtypes)) {
return false;
}
$term = $this->clean_term($term); // etc
}
The error it throws is something like:
A PHP Error was encountered
Severity: 4096
Message: Argument 1 passed to gb::search() must be an instance of stdClass, null given, called in /application/models/gb.php on line 20 and defined

Any ideas how to approach this from a CodeIgniter point of view?
if I remember - mistyped argument should raise E_RECOVERABLE_ERROR, so, it triggers error handler but execution continues. So, you have two options basically.
One is to throw exception in error handler when E_RECOVERABLE_ERROR is encountered. To halt execution.
Another - check type with instanceof stdClass and do what you suppose - raise exception or return something.
UPDATE In your case your framework (CI is for CodeIgniter?) sets error handler (somewhere using set_error_handler). So, after logging or printing error message execution continues. (If there was not handler you would get fatal error). Just test type of argument manually:
function search(stdClass $options){
// test type for sure, because of recoverable error
if (!($options instanceof stdClass)) {
return false; // or throw new InvalidArgumentException('Parameter should be instance of stdClass');
}
$term = $options->term;
$type = $options->type;
// make sure we're doing a valid search
if (!$term || !in_array($type, $this->searchtypes)) {
return false;
}
$term = $this->clean_term($term); // etc
}
