I would like to add some strings/values to the end of the generated pagination link.
For example, I get this
http://localhost/products/lists/5
I would like to have
http://localhost/products/lists/5/value/anothervalue
So, I need to send those values somehow... :)
Thank u all.
The pagination class has an undocumented configuration option called suffix that you can use. Here's how I use it in one of my apps:
// get the current url segments and remove the ones before the suffix
// http://localhost/products/lists/5/value/anothervalue
$args = $this->uri->segment_array();
unset($args[1], $args[2], $args[3]);
$args = implode('/', $args);
// $args is now 'value/anothervalue'
$base_url = 'http://localhost/products/lists';
$this->pagination->initialize(array(
'base_url' => $base_url,
'suffix' => '/'.$args,
'first_url' => $base_url.'/1/'.$args,
'uri_segment' => 3
));
The application/config/routes.php
$route['products/lists/(:num)/value/(:any)'] = "products/lists/$1/$2";
The controller code application/controllers/products.php
class Products extends CI_Controller {
public function index() {
$this->load->view('welcome_message');
}
public function lists($page = 1, $value = null) {
$this->load->view('product_lists', array('page' => $page, 'value' => $value));
}
}
In this way if your url is like http://localhost/products/lists/5/value/anothervalue
in function lists will be $page = 5 and $value = 'anothervalue' and they will be available in template product_lists ($page, $value)

The problem is when I entered a new name no data is added. A similar thing happen when I entered an already existing name. Still, no data is added to the database. I am still new to CodeIgniter and not entirely sure my query builder inside the model is correct or not.
In the Model, I check if the name already exists insert data only into the phone_info table. IF name does not exist I insert data into user_info and phone_info.
Controller:
public function addData()
{
$name = $this->input->post('name');
$contact_num = $this->input->post('contact_num');
if($name == '') {
$result['message'] = "Please enter contact name";
} elseif($contact_num == '') {
$result['message'] = "Please enter contact number";
} else {
$result['message'] = "";
$data = array(
'name' => $name,
'contact_num' => $contact_num
);
$this->m->addData($data);
}
echo json_encode($result);
}
Model:
public function addData($data)
{
if(mysqli_num_rows($data['name']) > 0) {
$user = $this->db->get_where('user_info', array('name' => $data['name']))->result_array();
$user_id = $user['id'];
$phone_info = array(
'contact_num' => $data['contact_num'],
'user_id' => $user_id
);
$this->db->insert('phone_info',$phone_info);
} else {
$user_info = array(
'name' => $data['name']
);
$this->db->insert('user_info', $user_info);
$user = $this->db->get_where('user_info', array('name' => $data['name']))->result_array();
$user_id = $user['id'];
$phone_info = array(
'contact_num' => $data['contact_num'],
'user_id' => $user_id
);
$this->db->insert('phone_info', $phone_info);
}
}
DB-Table user_info:
DB-Table phone_info:
Extend and change your model to this:
public function findByTitle($name)
{
$this->db->where('name', $name);
return $this->result();
}
public function addData($data)
{
if(count($this->findByTitle($data['name'])) > 0) {
//.. your code
} else {
//.. your code
}
}
Explanation:
This:
if(mysqli_num_rows($data['name']) > 0)
..is not working to find database entries by name. To do this you can use codeigniters built in model functions and benefit from the MVC Pattern features, that CodeIgniter comes with.
I wrapped the actual findByName in a function so you can adapt this to other logic and use it elswehere later on. This function uses the query() method.
Read more about CodeIgniters Model Queries in the documentation.
Sidenote: mysqli_num_rows is used to iterate find results recieved by mysqli_query. This is very basic sql querying and you do not need that in a MVC-Framework like CodeIgniter. If you every appear to need write a manual sql-query, even then you should use CodeIgniters RawQuery methods.
I have a model that has a one to many relationship to the versions of the description.
In my Controller
$tag = Tags::create([
'name' => $request->get('name'),
'user_id' => \Auth::id(),
]);
$tag->update([
'content' => $request->get('description')
]);
In my Model:
public function setContentAttribute(string $value)
{
$this->versions()->create([
'user_id' => \Auth::id(),
'value' => $value
]);
}
So I can't put content directly as an attribute in the create method because there is no Model right now.
But is it possible to overwrite the create Method?
When I try to overwrite something like this in my Model it will do an infinity loop
public static function create($attr) {
return parent::create($attr);
}
So my question is if it is possible to have something like this:
$tag = Tags::create([
'name' => $request->get('name'),
'user_id' => \Auth::id(),
'content' => $request->get('content')
]);
and in the Model:
public static function create($attr) {
$value = $attr['content'];
$attr['content'] = null;
$object = parent::create($attr);
$object->content = $value;
$object->save();
return $object;
}
Update
I didn't overwrite the create method but called it customCreate. So there is no infinity loop anymore and I can pass all variables to the customCreate function that handles the relationships for me.
Solution
After reading the changes from 5.3 to 5.4 it turns out that the create method was moved so you don't have to call parent::create() anymore.
The final solution is:
public static function create($attr) {
$content = $attr['content'];
unset($attr['content']);
$element = static::query()->create($attr);
$element->content = $content;
$element->save();
return $element;
}
I don't see why not and you could probably implement a more general approach? Eg. checking if set{property}Attribute() method exists, if it does - use it to assign a value, if it doesn't - use mass assigning.
Something like:
public static function create($attr) {
$indirect = collect($attr)->filter(function($value, $property) {
return method_exists(self::class, 'set' . camel_case($property) . 'Attribute');
});
$entity = parent::create(array_diff_key($attr, $indirect->toArray()));
$indirect->each(function($value, $property) use ($entity) {
$entity->{$property} = $value;
});
$entity->save();
return $entity;
}
I haven't really tested it but it should work. I use something like this in one of my Symfony apps.
I have some problem with routing and parameters.
I have routing in routes.php like this :
$route['register/(:any)'] = 'member/register/$1';
And in my controller I have like this :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Register extends CI_Controller
{
function __construct()
{
parent::__construct();
$this->load->model('Page_model');
$this->load->model('member_model');
$this->load->model('login_model');
$this->load->library('session');
$this->load->helper('url');
$this->load->helper('html');
$this->load->helper('form');
}
public function index()
{
$slug = $this->uri->segment(1);
$type = $this->uri->segment(2);
var_dump($type);
exit();
if ($slug != NULL)
{
$data['page'] = $this->Page_model->get_page($slug);
if (empty($data['page']))
{
// show_404();
$data['page'] = new stdClass();
$data['page']->page_template = 'forofor';
$data['page']->title = 'Page Not Found';
$data['page']->meta_description = 'Page Not Found';
$data['page']->meta_keywords = 'Page Not Found';
}
else
{
$data['slider'] = $this->Page_model->get_slider($data['page']->page_id);
}
}
else
{
$data['page'] = $this->Page_model->get_page('home');
$data['slider'] = $this->Page_model->get_slider($data['page']->page_id);
}
$data['head_title'] = $data['page']->title;
// load all settings and data
$data['settings'] = $this->Page_model->get_settings();
$data['gallery'] = $this->Page_model->get_gallery();
$data['meta'] =
array(
array(
'name' => 'description',
'content' => $data['page']->meta_description
),
array(
'name' => 'keywords',
'content' => $data['page']->meta_keywords
)
);
// $data['meta'] = $this->meta;
$data['menu'] = $this->Page_model->get_menu('frontend','header');
$data['settings'] = $this->Page_model->get_settings();
$data['notice'] = $this->session->flashdata('notice');
// $this->load->view('frontend/template/index_full', $data);
$this->load->view('frontend/template/head', $data);
$this->load->view('frontend/template/pre_header');
$this->load->view('frontend/template/header');
$this->load->view('frontend/template/modal');
//$this->load->view('frontend/template/modal_registration');
/*if ($page[0]->page_template != 'forofor' && $data['page']->slider != 0)
{
$this->load->view('frontend/template/slider');
}*/
if ($slug != 'home' && $slug != NULL)
{
//$this->load->view('member/'.$data['page']->page_template);
$this->load->view('member/register');
}
else
{
$this->load->view('frontend/template/slider');
$this->load->view('frontend/page_template/homepage');
}
$this->load->view('frontend/template/pre_footer');
$this->load->view('frontend/template/footer');
$this->load->view('frontend/template/js');
$this->load->view('frontend/template/closing_body_html');
}
}
But if I input the routes in my browser it gives me 404 Page not found
This is my routes :
127.0.0.1/project/register/buyer
And 127.0.0.1/project/ is my Base URL
Anyone knows why it could be happen ?
Thank you.
Your routing is wrong. According to your post you are setting Member controller then register method.
Try below code
$route['register/(:any)'] = 'register/index/$1';
$route['register/(:any)/(:any)'] = 'register/index/$1/$2'; // Optional
The second option is only optional:
This is how routes work in Codeigniter
Typically there is a one-to-one relationship between a URL string and
its corresponding controller class/method. The segments in a URI
normally follow this pattern:
example.com/class/function/id/ In some instances, however, you may
want to remap this relationship so that a different class/method can
be called instead of the one corresponding to the URL.
For example, let’s say you want your URLs to have this prototype:
example.com/product/1/ example.com/product/2/ example.com/product/3/
example.com/product/4/ Normally the second segment of the URL is
reserved for the method name, but in the example above it instead has
a product ID. To overcome this, CodeIgniter allows you to remap the
URI handler.
Reference : https://www.codeigniter.com/userguide3/general/routing.html
So,the routes follow this syntax
$route['route_url'] = 'controller/method/$paramater';
So,your route will be
Let me know your queries
$route['register/(:any)'] = 'register/index/$1';
I have been doing frontend magento for a while but have only just started building modules. This is something i know how to do frontend but i am struggling with in my module. What i am trying to achieve for now, is populating a multiselect in the admin with all available product attributes. Including custom product attributes across all product attribute sets. I'm not entirely sure what table this will require because i don't want to assume that Flat Category Data is enabled.
I have created my admin area in a new tab in system config, i have created a multiselect field that is currently just being populated with three static options. This much works. Could anyone help me by pointing a finger in the right direction... currently this is what i have so far (for what it's worth).
<?php
class test_test_Model_Source
{
public function toOptionArray()
{
return array(
array('value' => 0, 'label' =>'First item'),
array('value' => 1, 'label' => 'Second item'),
array('value' => 2, 'label' =>'third item'),
);
}
}
///////////////////////////// EDIT /////////////////////////////////////
I feel like i might be onto something here, but it's only returning the first letter of every attribute (so i'm not sure if its even the attributes its returning)
public function toOptionArray()
{
$attributes = Mage::getModel('catalog/product')->getAttributes();
$attributeArray = array();
foreach($attributes as $a){
foreach($a->getSource()->getAllOptions(false) as $option){
$attributeArray[$option['value']] = $option['label'];
}
}
return $attributeArray;
}
///////////////////////////////// EDIT //////////////////////////////////////
I am not extremely close as i now know that the array is returning what i want it to, all attribute_codes. However it is still only outputting the first letter of each... Anyone know why?
public function toOptionArray()
{
$attributes = Mage::getModel('catalog/product')->getAttributes();
$attributeArray = array();
foreach($attributes as $a){
foreach ($a->getEntityType()->getAttributeCodes() as $attributeName) {
$attributeArray[$attributeName] = $attributeName;
}
break;
}
return $attributeArray;
}
I have answered my own question. I have found a way that worked however i'm not sure why, so if someone could comment and explain that would be useful. So although having $attributeArray[$attributeName] = $attributeName; worked when it came to a print_r when you returned the array it was only providing the first letter. However if you do the following, which in my opinion seems to be doing exactly the same thing it works. I can only imagine that when rendering it wasn't expecting a string but something else. Anyway, here is the code:
public function toOptionArray()
{
$attributes = Mage::getModel('catalog/product')->getAttributes();
$attributeArray = array();
foreach($attributes as $a){
foreach ($a->getEntityType()->getAttributeCodes() as $attributeName) {
//$attributeArray[$attributeName] = $attributeName;
$attributeArray[] = array(
'label' => $attributeName,
'value' => $attributeName
);
}
break;
}
return $attributeArray;
}
No need to do additional loops, as Frank Clark suggested. Just use:
public function toOptionArray()
{
$attributes = Mage::getResourceModel('catalog/product_attribute_collection')->addVisibleFilter();
$attributeArray = array();
foreach($attributes as $attribute){
$attributeArray[] = array(
'label' => $attribute->getData('frontend_label'),
'value' => $attribute->getData('attribute_code')
);
}
return $attributeArray;
}
You can try to get attributes in other way, like this
$attributes = Mage::getSingleton('eav/config')
->getEntityType(Mage_Catalog_Model_Product::ENTITY)->getAttributeCollection();
Once you have attributes you can get options in this way (copied from magento code)
$result = array();
foreach($attributes as $attribute){
foreach ($attribute->getProductAttribute()->getSource()->getAllOptions() as $option) {
if($option['value']!='') {
$result[$option['value']] = $option['label'];
}
}
}
<?php
class Home extends CI_Controller
{
public function __construct()
{
// load libraries //
$this->load->library('session');
$this->load->library('database');
$this->load->library('captcha');
// alternative
$this->load->library(array('session', 'database', 'captcha'));
// load models //
$this->load->model('menu_model', 'mmodel');
$this->load->model('user_model', 'umodel');
$this->load->model('admin_model', 'amodel');
// alternative
$this->load->model(array(?));
}
}
?>
How can i load all models in array? is it possible?
For models, you can do this:
$models = array(
'menu_model' => 'mmodel',
'user_model' => 'umodel',
'admin_model' => 'amodel',
);
foreach ($models as $file => $object_name)
{
$this->load->model($file, $object_name);
}
But as mentioned, you can create file application/core/MY_Loader.php and write your own method for loading models. I think this might work (not tested):
class MY_Loader extends CI_Loader {
function model($model, $name = '', $db_conn = FALSE)
{
if (is_array($model))
{
foreach ($model as $file => $object_name)
{
// Linear array was passed, be backwards compatible.
// CI already allows loading models as arrays, but does
// not accept the model name param, just the file name
if ( ! is_string($file))
{
$file = $object_name;
$object_name = NULL;
}
parent::model($file, $object_name);
}
return;
}
// Call the default method otherwise
parent::model($model, $name, $db_conn);
}
}
Usage with our variable from above:
$this->load->model($models);
You could also allow a separate DB connection to be passed in an array, but then you'd need to have a multidimensional array, and not the simple one we used. It's not too often you'll need to do that anyways.
I don't have any idea about the CodeIgniter 2.x but in CodeIgniter 3.x, this will also works :
$models = array(
'menu_model' => 'mmodel',
'user_model' => 'umodel',
'admin_model' => 'amodel',
);
$this->load->model($models);
Not natively, but you can easily extend Loader->model() to support that logic.
This work fine for me:
$this->load->model(array('menu_model'=>'menu','user_model'=>'user','admin_model'=>'admin'));
