Magento 2 Minicart - Display line item subtotal rather than unit price

url: https://magento.stackexchange.com/questions/173028/magento-2-minicart-display-line-item-subtotal-rather-than-unit-price

 

 Final Solution,

You can get item qty using $qty = $item->getQty(); Now just you have to set $block->getUnitDisplayPriceInclTax()*$qty to get lineItem subtotal for each item.

<?php
/** @var $block \Magento\Weee\Block\Item\Price\Renderer */
$item = $block->getItem();

$originalZone = $block->getZone();
$block->setZone(\Magento\Framework\Pricing\Render::ZONE_CART);
/* custom logic*/
$qty = $item->getQty();
?>
<?php if ($block->displayPriceInclTax() || $block->displayBothPrices()): ?>
    <span class="price-including-tax" data-label="<?php echo $block->escapeHtml(__('Incl. Tax')); ?>">
    <?php if ($block->displayPriceWithWeeeDetails()): ?>
        <span class="minicart-tax-total">
    <?php else: ?>
        <span class="minicart-price">
    <?php endif; ?>
        <!-- custom logic -->
        <?php /* @escapeNotVerified */ echo $block->formatPrice($block->getUnitDisplayPriceInclTax()*$qty); ?>
        </span>

    <?php if ($block->displayPriceWithWeeeDetails()): ?>
        <?php if ($this->helper('Magento\Weee\Helper\Data')->getApplied($item)): ?>
            <span class="minicart-tax-info">
            <?php foreach ($this->helper('Magento\Weee\Helper\Data')->getApplied($item) as $tax): ?>
                <span class="weee" data-label="<?php /* @escapeNotVerified */ echo $tax['title']; ?>">
                    <?php /* @escapeNotVerified */ echo $block->formatPrice($tax['amount_incl_tax'], true, true); ?>
                </span>
            <?php endforeach; ?>
            </span>

            <?php if ($block->displayFinalPrice()): ?>
                <span class="minicart-tax-total">
                    <span class="weee" data-label="<?php echo $block->escapeHtml(__('Total Incl. Tax')); ?>">
                        <!-- custom logic -->
                        <?php /* @escapeNotVerified */ echo $block->formatPrice($block->getFinalUnitDisplayPriceInclTax()*$qty); ?>
                    </span>
                </span>
            <?php endif; ?>
        <?php endif; ?>
    <?php endif; ?>
    </span>
<?php endif; ?>

<?php if ($block->displayPriceExclTax() || $block->displayBothPrices()): ?>
    <span class="price-excluding-tax" data-label="<?php echo $block->escapeHtml(__('Excl. Tax')); ?>">
    <?php if ($block->displayPriceWithWeeeDetails()): ?>
        <span class="minicart-tax-total">
    <?php else: ?>
        <span class="minicart-price">
    <?php endif; ?>
        <!-- custom logic -->
        <?php /* @escapeNotVerified */ echo $block->formatPrice($block->getUnitDisplayPriceExclTax()*$qty); ?>
        </span>

    <?php if ($block->displayPriceWithWeeeDetails()): ?>
        <?php if ($this->helper('Magento\Weee\Helper\Data')->getApplied($item)): ?>
            <span class="minicart-tax-info">
            <?php foreach ($this->helper('Magento\Weee\Helper\Data')->getApplied($item) as $tax): ?>
                <span class="weee" data-label="<?php /* @escapeNotVerified */ echo $tax['title']; ?>">
                    <?php /* @escapeNotVerified */ echo $block->formatPrice($tax['amount'], true, true); ?>
                </span>
            <?php endforeach; ?>
            </span>

            <?php if ($block->displayFinalPrice()): ?>
                <span class="minicart-tax-total">
                    <span class="weee" data-label="<?php echo $block->escapeHtml(__('Total')); ?>">
                        <!-- custom logic -->
                        <?php /* @escapeNotVerified */ echo $block->formatPrice($block->getFinalUnitDisplayPriceExclTax()*$qty); ?>
                    </span>
                </span>
            <?php endif; ?>
        <?php endif; ?>
    <?php endif; ?>
    </span>
<?php endif; ?>
<?php $block->setZone($originalZone); ?>

In above file i have just comment as custom logic at which place i have added price multiply $qty to get lineitem subtotal.

Clear cache and check it again.
