I am using opencart and successfully added minimum order price for all transactions. This is the code I used:
<?php if ($this->cart->getSubtotal() >= 10) { ?> <div id="payment"><?php echo $payment; ?></div> <?php } else { ?> <div class="warning">Minimum 10 Euro to checkout</div> <?php } ?>
Now I want to exclude one category out of it so that $9 product from that category can be bought.
Update 1: Thank you so much for the help shadyyx
I tried shadyyx method but I am getting this error: unexpected T_BOOLEAN_OR in this line
<?php if ($this->cart->getSubtotal() >= 10 || $this->cart->productsAreInCategory(1)) { ?>
Update 2: I tried this but it gave a pop up saying just error and ok button <?php if (($this->cart->getSubtotal() >= 10) || $this->cart->productsAreInCategory(1)) { ?>
I tried this <?php if (($this->cart->getSubtotal() >= 10) || ($this->cart->productsAreInCategory(1))) { ?> it did not give any error and does same work (min amount for all orders regardless of category id)
I would go this way:
Extend the system/library/cart.php and add a method:
public function productsAreInCategory($category_id) { $product_ids = array(); foreach($this->getProducts() as $product) { $product_ids[] = $product['product_id']; } $categories = $this->db->query('SELECT category_id FROM ' . DB_PREFIX . 'product_to_category WHERE product_id IN (' . implode(',', $product_ids) . ')')->rows; $category_ids = array(); foreach($categories as $category) { $category_ids[] = $category['category_id']; } if(in_array($category_id, $category_ids) { return true; } return false; }
This method should accept a $category_id parameter to test against and should load categories for all products in cart. After first match a true is returned, if no match, a false is returned. You can now use this method this way:
<?php if (($this->cart->getSubtotal() >= 10) || $this->cart->productsAreInCategory(1)) { ?> <div id="payment"><?php echo $payment; ?></div> <?php } else { ?> <div class="warning">Minimum 10 Euro to checkout</div> <?php } ?>
Just replace the category ID in $this->cart->productsAreInCategory(1) with the correct one.
