I can not figure out how to call the function - El Forum - 10-15-2012

HellO!
Problem exists, there is the private function "delivery", which must have a value that comes into it.
Code:
class Catalog extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('mCatalog');
}
public function index() {
redirect(base_url(), 'location', 301);
}
public function id($catId = NULL, $num = 0) {
$data['catalog'] = $this->mCatalog->getCatalog($catId);
// $data['deliver'] = $this->delivery($num);
if ($data['catalog'] == FALSE) {
$data['error'] = "Category not found";
}
$this->load->view("vCatalog", $data);
}
private function delivery($num) {
if($num > 0) {
return $num."%";
} else {
return "Free!";
}
}It input parameter must be passed out of the array, which is obtained through the model database. In viewer this parameter is obtained from
Code:
<?php foreach ($catalog as $row): ?>
<td><?=$row['delivery']?></td>
<?endforeach?>Here it's the problem, can not figure out how to make that "delivery" in the viewer took the $num. Thank you!

I think you should create and use a Helper function instead of your Controller function :
/helpers/myhelper_helper.php
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
if ( ! function_exists('delivery')) {
function delivery($num) {
if($num > 0) {
return $num."%";
} else {
return "Free!";
}
}
}/controllers/catalog.php
Code:
public function id($catId = NULL, $num = 0) {
$data['catalog'] = $this->mCatalog->getCatalog($catId);
if ($data['catalog'] == FALSE) {
$data['error'] = "Category not found";
} else {
$this->load->helper('myhelper');
foreach ($data['catalog'] as $catalog) {
$catalog['delivery'] = delivery($catalog['delivery']);
}
}
$this->load->view("vCatalog", $data);

Thank you!
But as we now bring in the viewer to the bulkhead viewer in "foreach" array did not take the last entry in the array controller parameter "delivery"?
Code:
xdebug_var_dump($catalog['delivery']);gives value to the controller
Code:
string '5%' (length=2)
string '4%' (length=2)
string 'Free!' (length=5)
string 'Free!' (length=5)yes - this is the correct data.
but in the viewer now insert with loop through the array $date['catalog']?

Your view should remain the same :
Code:
<?php foreach ($catalog as $row): ?>
<td><?=$row['delivery']?></td>
<?endforeach?>The "delivery" field displayed here has been changed into your controller, through the helper function, and will output "5%" or 'Free!" like in your var_dump()

But in your case, the controller is "delivery" is written to the array $catalog and viewer displays the loop array of $data.
That's what gives me var_dump in your example:
Code:
string '5' (length=1)
string '4' (length=1)
string '0' (length=1)
string '0' (length=1)From the controller just an array $catalog does not get in the viewer. that's the problem

In your controller you should have
Code:
foreach ($data['catalog'] as $catalog) {Meaning that $catalog is part of $data!
$catalog is each element of the $data variable passing through the loop.
So when next line you got
Code:
$catalog['delivery'] = delivery($catalog['delivery']);So in the foreach loop, when you change $catalog, $data changes too, and as it's passed to your view, it should display the right data.
Gimme your code from Helper/Model/Controller/View please. I don't get it.

Hmmm
I made a call to a helper in the "viewer" and it worked as it should. That is processing in the controller is not needed, since necessary data to be passed in a single cycle.
View
Code:
$this->load->helper('catalog_helper');
foreach ($catalog as $row) {
<td><?=delivery($row['delivery'])?></td>
}
