在opencart管理面板中过滤所有数量<= 10的产品

Question

I want to get all product between 1 and 10 quantity in my admin panel Here's the data in my controller:

    $enabled_product = $this->model_catalog_product->getTotalNumberOfEnabledProductsWithLessOrEqualTo10Quantity();

    $data['enabled_product'] = $enabled_product;

    $data['enabled_product_link'] = $this->url->link('catalog/product', 'token=' . $this->session->data['token'] . '&filter_quantity=10&filter_status=1', true);

    $data['enabled_product_link'] = $this->url->link('catalog/product', 'token=' . $this->session->data['token'] . '&filter_quantity<=10&filter_status=1', true);

I'm trying to tell the url that i want all products with quantity <= 10 and status = 1 Here's the url:

http://local.loc/admin/index.php?route=catalog/product&token=lNcGHcKRXDz02nQlrw83sRB7UzV4HViz&filter_quantity<=10&filter_status=1

The problem is that i can get all products if they are only equal to specific number. I also tried the following url:

http://local.loc/admin/index.php?route=catalog/product&token=lNcGHcKRXDz02nQlrw83sRB7UzV4HViz&filter_quantity=10&filter_quantity=9&filter_quantity=8&filter_quantity=7&filter_quantity=6&filter_quantity=5&filter_status=1

But did not work. Any ideas how can i get all products with quantity <=10 ?

Answer 1

from a REST perspective you should pass it like that in the url

&lesseq=10&filter_status=1

where lesseq should be <= for the filter_quantity variable however please check REST URL design for greater than, less than operations as i believe you can implement exactly the same Answer

Answer 2

Use one of these methods:

In admin\\model\\catalog\\product.php

Find: $sql .= " AND p.quantity = '" . (int)$data['filter_quantity'] . "'"; $sql .= " AND p.quantity = '" . (int)$data['filter_quantity'] . "'";

There are two matches.

Change them to: $sql .= " AND p.quantity <= '" . (int)$data['filter_quantity'] . "'"; $sql .= " AND p.quantity <= '" . (int)$data['filter_quantity'] . "'";

Now this will show all products with quantity 10 or less than 10:

http://local.loc/admin/index.php?route=catalog/product&token=lNcGHcKRXDz02nQlrw83sRB7UzV4HViz&filter_quantity=10&filter_status=1

OR

In admin\\controller\\catalog\\product.php

Find: 'filter_quantity' => $filter_quantity,

Add after: 'filter_quantity_less' => isset($this->request->get['filter_quantity_less']) ? $this->request->get['filter_quantity_less'] : null, 'filter_quantity_less' => isset($this->request->get['filter_quantity_less']) ? $this->request->get['filter_quantity_less'] : null,

In admin\\model\\catalog\\product.php

Find: if (isset($data['filter_quantity']) && !is_null($data['filter_quantity'])) {

There are two matches, add before them:

if (isset($data['filter_quantity_less']) && !is_null($data['filter_quantity_less'])) {
    $sql .= " AND p.quantity <= '" . (int)$data['filter_quantity_less'] . "'";
}

Now you can use it in url like this:

filter_quantity_less=10
