When are you going to quit writing code and start to learn the languages and frameworks?
RE: Edit Pages - davy_yg - 08-27-2016
Sorry, I thought that is CI framework. And I know somethings about php - already 4 years with php. Eventhough some errors makes me question something?
RE: Edit Pages - ciadmin - 08-27-2016
Davy: the error message you are questioning is pure PHP ... "Invalid argument supplied for foreach()".
The $pages variable is either empty or undefined.
That should be apparent to someone with four years of PHP
RE: Edit Pages - PaulD - 08-27-2016
Should be apparent with four weeks of php.
RE: Edit Pages - davy_yg - 08-27-2016
Lol. I think I am still new in this part and perhaps better on other part. I already read the manual and still do not understand it.
http://php.net/manual/en/control-structures.foreach.php
I try to activate this:
<?php $pages=array(); ?>
<?php foreach ($pages as $pages_item): ?>
RE: Edit Pages - davy_yg - 08-27-2016
This is the models:
models/Mpages.php
PHP Code:
public function update_pages($pages_id)
{
$data = array(
'pages_name' => $this->input->post('pages_name'),
'create_date' => $this->input->post('create_date'),
'pages_order' => $this->input->post('pages_order'),
'pages_content' => $this->input->post('pages_content')
);
$this->db->where('pages_id', $pages_id);
return $this->db->update('pages', $data);
}

Learn to program in PHP
RE: Edit Pages - davy_yg - 08-28-2016
I have read the tutorial. I only do not know how to fix this error message:

RE: Edit Pages - ciadmin - 08-28-2016
Davy: I repeat, the $pages variable is either empty or undefined.
The model snippet you provided earlier does not set $pages, as far as I can see.
In line 49 of your post above, where does $pages come from????????????
It is empty or undefined!!!!!!!!!!!!!
