How to add do_action in echo? - php

Question

Maybe a crazy question, but I need to put below code in echo and I am getting an error. Basically I want to hide add to cart section from not logged in users and show them different content/button
This whole code
<div class="woocommerce-variation-add-to-cart variations_button">
<?php do_action( 'woocommerce_before_add_to_cart_button' ); ?>
<?php
do_action( 'woocommerce_before_add_to_cart_quantity' );
woocommerce_quantity_input(
array(
'min_value' => apply_filters( 'woocommerce_quantity_input_min', $product->get_min_purchase_quantity(), $product ),
'max_value' => apply_filters( 'woocommerce_quantity_input_max', $product->get_max_purchase_quantity(), $product ),
'input_value' => isset( $_POST['quantity'] ) ? wc_stock_amount( wp_unslash( $_POST['quantity'] ) ) : $product->get_min_purchase_quantity(), // WPCS: CSRF ok, input var ok.
)
);
do_action( 'woocommerce_after_add_to_cart_quantity' );
?>
<button type="submit" class="single_add_to_cart_button button alt"><?php echo esc_html( $product->single_add_to_cart_text() ); ?></button>
<?php do_action( 'woocommerce_after_add_to_cart_button' ); ?>
<input type="hidden" name="add-to-cart" value="<?php echo absint( $product->get_id() ); ?>" />
<input type="hidden" name="product_id" value="<?php echo absint( $product->get_id() ); ?>" />
<input type="hidden" name="variation_id" class="variation_id" value="0" />
</div>
in here
<?php
if ( is_user_logged_in() ) {
echo 'THAT CODE SHOULD GO HERE';
} else {
echo 'Welcome, visitor!';
}
?>

Answer 1

You can do :
<?php
if ( is_user_logged_in() ) {
?>
<div class="woocommerce-variation-add-to-cart variations_button">
<?php do_action( 'woocommerce_before_add_to_cart_button' ); ?>
<?php
do_action( 'woocommerce_before_add_to_cart_quantity' );
woocommerce_quantity_input(
array(
'min_value' => apply_filters( 'woocommerce_quantity_input_min', $product->get_min_purchase_quantity(), $product ),
'max_value' => apply_filters( 'woocommerce_quantity_input_max', $product->get_max_purchase_quantity(), $product ),
'input_value' => isset( $_POST['quantity'] ) ? wc_stock_amount( wp_unslash( $_POST['quantity'] ) ) : $product->get_min_purchase_quantity(), // WPCS: CSRF ok, input var ok.
)
);
do_action( 'woocommerce_after_add_to_cart_quantity' );
?>
<button type="submit" class="single_add_to_cart_button button alt"><?php echo esc_html( $product->single_add_to_cart_text() ); ?></button>
<?php do_action( 'woocommerce_after_add_to_cart_button' ); ?>
<input type="hidden" name="add-to-cart" value="<?php echo absint( $product->get_id() ); ?>" />
<input type="hidden" name="product_id" value="<?php echo absint( $product->get_id() ); ?>" />
<input type="hidden" name="variation_id" class="variation_id" value="0" />
</div>
<?php
} else {
echo 'Welcome, visitor!';
}
?>

Please, you should be able to do this yourself. But here it is:
<?php
if(is_user_logged_in()){
echo "<div class='woocommerce-variation-add-to-cart variations_button'>";
do_action( 'woocommerce_before_add_to_cart_button' );
do_action( 'woocommerce_before_add_to_cart_quantity' );
woocommerce_quantity_input(
array(
'min_value' => apply_filters( 'woocommerce_quantity_input_min', $product->get_min_purchase_quantity(), $product ),
'max_value' => apply_filters( 'woocommerce_quantity_input_max', $product->get_max_purchase_quantity(), $product ),
'input_value' => isset( $_POST['quantity'] ) ? wc_stock_amount( wp_unslash( $_POST['quantity'] ) ) : $product->get_min_purchase_quantity(), // WPCS: CSRF ok, input var ok.
)
);
do_action( 'woocommerce_after_add_to_cart_quantity' );
echo "<button type='submit' class='single_add_to_cart_button button alt'>".echo esc_html( $product->single_add_to_cart_text() );."</button>";
do_action( 'woocommerce_after_add_to_cart_button' );
echo "<input type='hidden' name='add-to-cart' value='".echo absint( $product->get_id() );."' />
<input type='hidden' name='product_id' value='".echo absint( $product->get_id() );."' />
<input type='hidden' name='variation_id' class='variation_id' value='0' />
</div>
}";
} else {
echo 'Welcome, visitor!';
}
?>
Although the other answer by Jonathan is better.
