I'm using CakePHP to create a products database system. In CakePHP, I have an array of all products in the 'products' table. Each product (an element in the 'products' array) has a function 'toArray()'. This converts the product into an associative array. How could I take an array of all the products and add the 'toArray()' of each product to a new array. This is my current flow:
$products = [$product1, $product2, $product3];
$newArr = [];
foreach($products as $product) {
$newArr[] = $product->toArray();
}
Is there a one-liner for something like this?
I don't think you could quite oneline this (without functionalizing it, anyway), but you don't need to duplicate data unless you need to keep the original format as well as the reformatted version.
foreach($products as $key => $product){
$products[$key] = $product->toArray();
}
Will change your exisiting array to the reformatted version.

I am constructing a function that is making a call with API to db and returns me JSON data. The json contains orders and I have already decoded them in php array. Every order has properties such as "product_id" and "quantity". I want to temporarily store the "quantity" property somewhere because I need to sum all the products with the same product_id. Any suggestion how to do this?
I'm in a bit of a hurry, but wanted to see if I could help you out.
$quantities = [];
//Loop through all the orders
foreach ($orders as $order) {
//Loop through the orderrows
foreach ($order->getOrderRows() as $orderRow) {
if (array_key_exists($orderRow->getProductName(), $quantities)) {
//The product is already in the quantities array, so the quantity of this orderrow is added to the total
$quantities[$orderRow->getProductName()] =
($quantities[$orderRow->getProductName()] + (int) $orderRow->getItemQuantity());
} else {
//If this is the first time the product is encountered add the product and its quantity to the quantities array
$quantities[$orderRow->getProductName()] = (int) $orderRow->getItemQuantity();
}
}
}
This is going to have the following result, showing you the product names along with their quantities:
$quantities = [
'foo' => 12,
'bar' => 3,
];
You may use the session variable to store these values.
Trying to figure out how to parse a collection and put multiple items into the same key in another collection.
Currently I'm doing this using an array and then I make a collection out of it, but the items inside are not of type Collection, each key is an array and I can't use methods like first() on those arrays. Yes, I can use [0] instead, but I'd prefer to have access to methods available for collections.
$some_array = [];
// Parsing the existing collection using foreach
foreach ($items_collection as $item) {
// Doing some checks
if ($item->some_attribute1 == 1
&& #$item->some_relation->some_attribute2
) {
// Putting the item into the array with a specific dynamic key
$some_array[$item->some_relation->some_attribute2][] = $item->some_relation;
}
else if ($item->some_attribute1 == 0
&& #$item->some_relation->some_attribute3) {
// Putting the item into the array with a specific dynamic key
$some_array[$item->some_relation->some_attribute3][] = $item->some_relation;
}
}
// Defining a new Collection
$new_collection = new Collection();
// Parsing the array of groups of items and putting them in the newly created Collection by their key
foreach ($some_array as $key => $key_items) {
$new_collection->put($key, $key_items);
}
If to make something like this
$some_collection = new Collection();
foreach ($items_collection as $item) {
if ($item->some_attribute1 == 1
&& #$item->some_relation->some_attribute2
) {
$some_collection->put($item->some_relation->some_attribute2, $item->some_relation);
}
else if ($item->some_attribute1 == 0
&& #$item->some_relation->some_attribute3) {
$some_collection->put($item->some_relation->some_attribute3, $item->some_relation);
}
}
then instead of storing all the items in the same key the new items will just override the old ones. Is there a way to put multiple items in the same key using put()?
Thank you in advance!
Seems that the issue was that I wasn't converting the $key_items into a collection in the last foreach.
Now I just used the collect() method on $key_items to make it into a Collection and everything works now.
foreach ($some_array as $key => $key_items) {
$new_collection->put($key, collect($key_items));
}
I hope someone will find this workaround useful until a more elegant solution will be found.
I am trying to create an overview of product properties, for an invoice system.
So far, most things are comming together using classes and PDO.
I have the following issue.
In my class, i've created a function that builds my products array.
It loads some information from the database, to build this array.
This array, i want to use to display all the products i have selected:
$prod1 - $prod1Name - $prod1Descr - $prod1Price
$prod2 - $prod2name - $prod2Descr - $prod2Price
etc.
I figured that the Associative array would help me creating columns.
Though the problem is, that i do not understand a bit how to create multiple lines and columns this way.
I was thinking of something like:
$prod[1]["name"] - $prod[1]["descr"] - etc
Then to use this in a foreach loop to create as many new lines as required.
The only thing i could come up with is on my index.php (as shown below), cause using an index (the [1] defenition) does not seem to work the way i think it should be implemented.
For my understanding, i assigend the var in my class as an array, then redefine an array when loading the database information.
Could anyone tell me how i could try to solve this issue?
I have the following class:
<?
class Invoice{
var $vendorID;
var $product = array();
function product_array(){
global $db;
$query = $db->conn->prepare('
SELECT ProductName, ProductDescription, ProductDuration, ProductPriceInclVat, ProductPriceExclVat, ProductVatType
FROM products WHERE VendorID = :VendorID
');
$array = array (
'VendorID' => $this->vendorID
);
$query->execute($array);
$result = $query->fetchall();
if (empty($result)){
echo"Could not find any products matching your criteria.";
die;
} else {
foreach($result as $row) {
$this->product = array("Name" => $row['ProductName'],
"Description" => $row['ProductDescription'],
"Duration" => $row['ProductDuration'],
"PriceExclVat" => $row['ProductPriceExclVat'],
"PriceInclVat" => $row['ProductPriceInclVat'],
"VatType" => $row['ProductVatType']
);
}
}
}
}
?>
and then i have the following code on my index.php:
<?
$invoice = new Invoice();
foreach ($invoice->product as $key => $value){
echo $key . "<br>";
echo $value . "$value";
echo "<br>";
}
?>
When you are assigning the result arrays to the product property you are overwriting the array every time. You need to append to the array instead, so something like:
$this->product = array();
foreach($result as $row) {
$this->product[] = array(...);
}
Alternatively, you could just assign the results of fetchAll to the product property if you don't need to rename the field keys (or you could alias them in the SQL).
$query = $db->conn->prepare('
SELECT ProductName as Name,
ProductDescription as Description,
ProductDuration as Duration,
ProductPriceInclVat as PriceInclVat,
ProductPriceExclVat as PriceExclVat,
ProductVatType as VatType
FROM products WHERE VendorID = :VendorID
');
$array = array (
'VendorID' => $this->vendorID
);
$query->execute($array);
$product = $query->fetchall(PDO::FETCH_ASSOC);
The $product is now in the format you require.
After this you can avoid foreach loop in class invoice.
Other thing i noticed that you have made function product_array() which is not called,
so in index.php you are getting empty array (defined in class Invoice).
So in Invoice class it should be
$product = product_array()
and product_array function should return the value.
I need to gather all of the available attributes for the given product and then create a multidimensional array with them. Hopefully you can create a multidimensional array with more than two dimensions? The resulting array declarations should look like this:
$simpleArray[$child->getVendor()][$child->getColor()]=$child->getPrice();
First I'm gathering all the attributes then adding them to a string where I can call each one later:
$_product = $this->getProduct();
$_attributes = Mage::helper('core')->decorateArray($this->getAllowAttributes());
//Gather all attribute labels for given product
foreach($_attributes as $_attribute){
$attributeString .= '[$child -> get' . ucfirst($_attribute->getLabel()) . '()]';
}
Then I'm attempting to append that string to the array to declare it:
foreach($childProducts as $child) { //cycle through simple products to find applicable
//CAITLIN you are going to need way to search for other attributes, GET list of attributes
$simpleArray. $attributeString =$child->getPrice();
}
Mage::log('The attributeString is '. $simpleArray. $attributeString, null, 'caitlin.log'); //This is logging as "The attributeString is Array74"
Any suggestions?
You'll need to use recursion to do what you're requesting without knowing the attribute names while writing the code.
This will loop through and provide all of the child product prices, in a multi dimensional array based on the configurable attributes. It assumes that $_product is the current product.
$attrs = $_product->getTypeInstance(true)->getConfigurableAttributesAsArray($_product);
$map = array();
foreach($attrs as $attr) {
$map[] = $attr['attribute_code'];
}
$childPricing = array();
$childProducts = $_product->getTypeInstance()->getUsedProducts();
foreach($childProducts as $_child) {
// not all of the child's attributes are accessible, unless we properly load the full product
$_child = Mage::getModel('catalog/product')->load($_child->getId());
$topLevel = array($child->getData($map[sizeof($map)]) => $_child->getPrice());
array_pop($map);
$childProducts = array_merge($childProducts,$this->workThroughAttrMap($map,$_child,$topLevel));
}
//print_r childProducts to test, later do whatever you were originally planning with it.
In the same controller include this:
protected function workThroughAttrMap(&$map,$child,$topLevel) {
$topLevel = array($child->getData($map[sizeof($map)]) => $topLevel);
array_pop($map);
if(sizeof($map) > 0) return workThroughAttrMap($map,$child,$topLevel);
else return $topLevel;
}
I haven't tested this code so there may be a few minor bugs.
There are a few things you could do to make the code a bit cleaner, such as moving the first $topLevel code into the function, making that an optional parameter and initializing it with the price when it doesn't exist. I also haven't included any error checking (if the product isn't configurable, the child product doesn't have its price set, etc).
i want to filter and paginate a product collection. everything is fine - except pagination. im just getting the whole collection back, instead of 3 items for the first page.
//fetch all visible products
$product_collection = Mage::getModel('catalog/product')->getCollection();
//set wanted fields (nescessary for filter)
$product_collection->addAttributeToSelect('name');
$product_collection->addAttributeToSelect('description');
$product_collection->addAttributeToSelect('price');
$product_collection->addAttributeToFilter('visibility', array('neq' => 1));
//filter by name or description
$product_collection->addFieldToFilter(array(
array('attribute'=>'name','like'=>$sTerm),
array('attribute'=>'description','like'=>$sTerm)
));
//filter for max price
foreach ($product_collection as $key => $item) {
if($item->getPrice() >= $priceTo){
$product_collection->removeItemByKey($key);
}
}
//pagination (THIS DOESNT WORK!)
$product_collection->setPageSize(3)->setCurPage(1);
//TEST OUTPUT
foreach ($product_collection as $product) {
echo $product->getName().'<br />';
}
thanks for your support!
You are so close! Try moving that $product_collection->setPageSize(3)->setCurPage(1); line before the first foreach() iteration over the collection.
Magento collections are lazy-loaded. Until you directly load() them (or implicitly load them via a call to count() or foreach()) you can modify the collection properties which affect the underlying query (EDIT: see note below). Once the collection has been loaded explicitly or implicitly though you will only get the members of the _items property that have been set.
FYI you can call clear() to leave the original query-affecting properties (filters, sorters, limits, joins, etc) in place and then add further properties.
HTH
EDIT: Actually, adjusting query properties is always possible regardless of _items load state, but the effect won't be visible until the collection is regenerated.
Thanks #Ben! You gave me the right hint. Now it does work! Basically I'm creating another collection and filter this one by the ids of the already filtered items. Afterwards its easy to add pagination to that new collection. That's the working code:
//fetch all visible products
$product_collection = Mage::getModel('catalog/product')->getCollection();
//set wanted fields (nescessary for filter)
$product_collection->addAttributeToSelect('name');
$product_collection->addAttributeToSelect('description');
$product_collection->addAttributeToSelect('price');
$product_collection->addAttributeToFilter('visibility', array('neq' => 1));
//filter by name or description
$product_collection->addFieldToFilter(array(
array('attribute'=>'name','like'=>$sTerm),
array('attribute'=>'description','like'=>$sTerm)
));
//filter for max price
foreach ($product_collection as $key => $item) {
if($item->getPrice() >= $priceTo){
$product_collection->removeItemByKey($key);
}
}
//build id array out of filtered items (NEW!)
foreach($product_collection as $item){
$arrProductIds[]=$item->getId();
}
//recreate collection out of product ids (NEW)
$product_filtered_collection = Mage::getModel('catalog/product')->getCollection();
$product_filtered_collection->addAttributeToFilter('entity_id', array('in'=>$arrProductIds));
//add pagination (on new collection) (NEW)
$product_filtered_collection->setPageSize(3)->setCurPage(1);
//TEST OUTPUT
foreach ($product_filtered_collection as $product) {
echo $product->getName().'<br />';
}
