Magento 2 Admin – How to Disable Reviews

Let's assume that your attribute has int type. In this case you can do something like this:

$collection = Mage::getModel('review/review')->getCollection()
    ->addStoreFilter(Mage::app()->getStore()->getId())
    ->addStatusFilter(Mage_Review_Model_Review::STATUS_APPROVED)
    ->setDateOrder()
    ->addRateVotes()
    ->setPageSize(5)
    ->setCurPage(1);

$collection->getSelect()
    ->join(array('attr' => 'catalog_product_entity_int'), 'attr.entity_id = main_table.entity_pk_value', array('*'))
    ->where('attr.attribute_id = 272');

Where 272 is the of your attribute id.

If you also want to limit a collection to reviews of products with specific attribute set to specific value you can add something like this to the end

->where('attr.value = 24')

Where 24 is the value of your attribute.

If your attribute has different type then just replace catalog_product_entity_int with EAV table of your attribute.

You have a typo in your code, bracket is in wrong place:

<?php if( count( $this->getReviewsCollection() > 0 ) ): ?>

It should be:

<?php if( count( $this->getReviewsCollection() ) > 0  ): ?>

However, it's better to use this code if you only want to check size of the collection:

<?php if( $this->getReviewsCollection()->getSize() > 0  ): ?>
