I am using code igniter. I have to make cart feature and I have to save product ids to cookie but I am not able to add array to cookie. My controller code to add cookie is
public function add_to_cart(){
$product_id = $this->uri->segment(3);
$cookie= array(
'name' => 'cookie_product',
'value' => $product_id,
'expire' => '3600',
);
$this->input->set_cookie($cookie);
var_dump($this->input->cookie('cookie_product',true));die;
}
$product_id has my product id for example 41 . need help !
You do not have to use cookies directly. Use cart library which will handle cookies for you.
https://www.codeigniter.com/userguide3/libraries/cart.html
$this->load->library('cart');
$data = array(
'id' => 'sku_123ABC',
'qty' => 1,
'price' => 39.95,
'name' => 'T-Shirt',
'options' => array('Size' => 'L', 'Color' => 'Red')
);
$this->cart->insert($data);
And to view items
<?php print_r($this->cart->contents()); ?>
Cart sounds like a good solution.
The reason why your original code wasn't working is you were trying to pass an array instead of breaking it into individual parameters.
If you did want to fix it, your code should be:
$this->input->set_cookie($cookie['name'], $cookie['value'], $cookie['expire']);
Incidentally, you can store an array in a cookie by using serialize and unserialize to store the cookie as a string instead of an array:
$this->input->set_cookie('cookie_product', serialize($cookie));
var_dump(unserialize($this->input->cookie('cookie_product',true)));

I am using tinymce for to add user cover letter related to the application.
This what my post array look like:
Array
(
[cover_letter] => <p>Test Cover Letter</p>
<ol>
<li>Need to save this data</li>
</ol>
<p><strong>Thanks</strong></p>
)
Simply I have used the require validation rule for this.
'candidate_cover_letter' => array(
array(
'field' => 'cover_letter',
'label' => 'Cover Letter',
'rules' => 'required'
)
)
I get the validation error regarding this like Cover Letter require.
I have two main problem:
How to validate HTML post array data
Is this best practice to save data like this? if no then how should i save this data?
First of all, in Codeigniter if we want to do form validations we need to go like this :
$config = array(
array(
'field' => 'username',
'label' => 'Username',
'rules' => 'required'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'required',
'errors' => array(
'required' => 'You must provide a %s.',
),
)
);
$this->form_validation->set_rules($config);
You can refer here
so, your code here should be like this in the controller:
$config =array(
array(
'field' => 'cover_letter',
'label' => 'Cover Letter',
'rules' => 'required'
)
);
$this->form_validation->set_rules($config);
You can add extra fields in the $config like the example above.
Another thing that you asked, "How you should save the data ?"
I would suggest you to use a field in the database table with type "TEXT" and it should be okay for you.
After you hit submit you get redirected back to your controller somewhere. One way to utilize CI form validation is:
//look to see if you have post data
if($this->input->post('submit')){
//points to applications/config/form_validation.php (look at next chucnk to set form_validation.php)
if($this->_validate('cover_letter')){
//rest of your post logic
//get data to upload to database
$data = [
'cover_letter'=>$this->input->post('cover_letter'),
'user_id'=>$this->input->post('user_id')
];
//save data to database ..also this should be moved to a model
$this->db->insert('name of table to insert into', $data);
}
//if you post doesnt not get validated you will fall here and if you have this chucnk of code in the same place were you have the logic to set up the cover letter you will see a pink message that says what ever error message you set up
}
Set up form validation.php
<?php
$config = [
//set up cover letter validation
//$this->_validate('cover_letter') maps to here and checks this array
'cover_letter' => [
[
'field'=>'cover_letter',
'label'=>'Cover Letter Required',//error message to return back to user
'rules'=>'required'//field is required
],
//example to add additional fields to check
[
'field'=>'observations',
'label'=>'Observations',
'rules'=>'required'
],
],
]
Hello All Knowledgeable persons in codeigniter,
I am using codeigniter cart system.
Here's is the structure of my codeigniter cart
$data = array(
'id' => $id,
'qty' => $qty,
'price' => $price,
'name' => $name,
'options' => array(
'picture'=>$img,
'item_slug'=>$slug,
'item_color'=>$color,
'item_size'=>$size,
'unit_price'=>$price,
'order_type'=>$order_type,
'product_type'=>$pro_type,
'unit_discount' => 0.00,
'total_discount' => 0.00,
'discount_type' => '',
)
);
Now I want to get the total total_discount on the cart, which i can do by a code-snippet like this
$tot_discount = 0.00;
foreach($this->cart->contents() as $ci)
{
$tot_discount = floatval($tot_discount + $ci['options']['total_discount'];
}
Now my question is, is there any inbuilt cart function to get sum of any numeric field of the options section in codeigniter? say like $this->cart->total() gives the total price of the cart.
Or I need to use the above code snippet?
Thanks in advance
While working with cart library in codeigniter, there are some fix parameters for cart that you need to set and some are optional.
Fixed Parameters
'id' => $id,
'qty' => $qty,
'price' => $price,
'name' => $name
Optional Parameters
'options' => array();
Actually options variable holds additional product specific information as you have specified and they may change subject to your business requirement. Now we have a common function total() as mentioned below:
$this->cart->total()
If you'll read the method definition then you'll find that it utilizes 'price' parameter for getting the total cart amount. Now as you have declared the 'total_discount' inside 'options' array, so there is a custom business requirement. So you can utilize the "total()" method definition to create your own function like "totalDiscount" because it varies product to product.
I'm trying to submit a form using PHP and the mailchimp 2.0 api.
I'm getting an error that says:
FNAME must be provided
My form has a field for the first name:
<input type="text" name="fname">
So it must have something to do with the way I am handling it the php side.
Here is the bit of php that handles FNAME:
$result = $MailChimp->call('lists/subscribe', array(
'id' => 'myid',
'email' => array( 'email' => $_POST['email']),
'FNAME' => $_POST['fname'],
'LNAME' => $_POST['lname'],
'double_optin' => false,
'update_existing' => true,
'replace_interests' => false
));
I'm not sure if I'm forming the array correctly or not.
By the way, I'm using this wrapper, but I think my error has to do with how I create $result and not the wrapper.
https://github.com/drewm/mailchimp-api
Any help would be appreciated.
Thanks!
Peep the example at the bottom of the page you linked to. I've pasted it here:
$result = $MailChimp->call('lists/subscribe', array(
'id' => 'b1234346',
'email' => array('email'=>'davy#example.com'),
'merge_vars' => array('FNAME'=>'Davy', 'LNAME'=>'Jones'),
'double_optin' => false,
'update_existing' => true,
'replace_interests' => false,
'send_welcome' => false,
));
print_r($result);
Your merge vars (ex. FNAME and LNAME) need to be in its own array. So, add a 'merge_vars' in your array and create an array that contains your field's merge variables.
I'm using magento 1.7.0.2. I have add the custom value in database. But how to retrive the custom value and image in Topmanu. I have tried in below mentioned code in the palce of 'my_attribute' to replace my attribute, but i din't get the result.
Model: Mage_Catalog_Model_Observer
Method: _addCategoriesToMenu()
$categoryData = array(
'name' => $category->getName(),
'id' => $nodeId,
//'url' => Mage::helper('catalog/category')->getCategoryUrl($category),
'is_active' => $this->_isActiveMenuCategory($category),
'my_attribute' => $category->getData('my_attribute') // Add our data in...
);
When i print the array i'll get this,
Array ( [name] => Matelas [id] => category-node-31 [is_active] => 1 [my_attribute] => )
Can any one guide me, Thanks in advance...
I am guessing you mean you have added a new custom attribute to the Category entity?
Becuase you are dealing with a Node_collection the full category object won't be loaded, try loading the full object to get what you're after:
$cat = Mage::getModel('catalog/category')->load($category->getId());
$categoryData = array(
name' => $category->getName(),
'id' => $nodeId,
//'url' => Mage::helper('catalog/category')->getCategoryUrl($category),
'is_active' => $this->_isActiveMenuCategory($category),
'my_attribute' => $cat->getData('my_attribute') // Add our data in...
);
Does anyone know how to properly insert new content categories to the DB programatically?
For each post in the categories table, there is also a post saved in the assets table with lft and rgt set.
Is there any native Joomla class I can use for this instead of plain SQL?
Please Please Only use the native classes, which categories will handle for you seamlessly. As soon as you add categories the whole thing will be handled automagically. Just look at any core component to see how.
It is not easy to update the assets table using sql, it is all very specifically managed and part of a complex series of foreign keyed tables.
Extend JTable or JTableContent to handle this.
Here is some code I just whipped together that just uses the JTableCategory class, so it can be used simply on the front or admin side of Joomla
$table = JTable::getInstance('category');
$data = array();
// name the category
$data['title'] = $title;
// set the parent category for the new category
$data['parent_id'] = $parent_id;
// set what extension the category is for
$data['extension'] = $extension;
// Set the category to be published by default
$data['published'] = 1;
// setLocation uses the parent_id and updates the nesting columns correctly
$table->setLocation($data['parent_id'], 'last-child');
// push our data into the table object
$table->bind($data);
// some data checks including setting the alias based on the name
if ($table->check()) {
// and store it!
$table->store();
// Success
} else {
// Error
}
Naturally you would want to get the data pieces set correctly, but these are the core ones to set.
Here is a function I've created just for this purpose, after some digging & experimenting.
It uses core classes, so it needs an access to them (for me it's basically a part of Joomla component).
Mind, it's for Joomla 3, for Joomla 2.5 and before, you need to change JModelLegacy to JModel.
function createCategory( $name, $parent_id, $note )
{
JTable::addIncludePath( JPATH_ADMINISTRATOR . '/components/com_categories/tables' );
$cat_model = JModelLegacy::getInstance( 'Category', 'CategoriesModel' );
$data = array (
'id' => 0,
'parent_id' => $parent_id,
'extension' => 'com_content',
'title' => $name,
'alias' => '',
'note' => $note,
'description' => '',
'published' => '1',
'access' => '1',
'metadesc' => '',
'metakey' => '',
'created_user_id' => '0',
'language' => '*',
'rules' => array(
'core.create' => array(),
'core.delete' => array(),
'core.edit' => array(),
'core.edit.state' => array(),
'core.edit.own' => array(),
),
'params' => array(
'category_layout' => '',
'image' => '',
),
'metadata' => array(
'author' => '',
'robots' => '',
),
);
if( !$cat_model->save( $data ) )
{
return NULL;
}
$categories = JCategories::getInstance( 'Content' );
$subcategory = $categories->get( $cat_model->getState( "category.id" ) );
return $subcategory;
}
You can perhaps use the save() in category.php file.
File location: root\administrator\components\com_categories\models\category.php
It saves the form data supplied to it!
The JOS_assets table is to store the ACL for each asset that is created.
If you do not update this table while programatically creating the category, the default ACL will apply. And when later you open and save the category in the administrative panel, the ACL will be updated as it should have been by core Joomla!.
You can create an SQL query very easily though and update the asset table as well. Its easy to understand once you open the table's content in phpmyadmin.
