ViewsUse esc_html__() method to output string plus a placeholder variable in WordPress
In a display of wordpress, I used the esc_html__() method to escape the string and add variables for safe use in HTML output.
My code is as follows:
<?php
global $product, $post;
$posts_id = $product->get_id();
$reserve_price = get_post_meta($posts_id, '_auction_reserved_price', true);
if ($product->is_reserved() === true && $product->is_reserve_met() === false) : ?>
<p class="reserve hold" data-auction-id="<?php echo esc_attr( $product->get_id() ); ?>">
<?php echo apply_filters('reserve_bid_text', esc_html__('Reserve price has not been met, needed to enter $ %s or more', 'wc_simple_auctions', $reserve_price)); ?>
</p>
<?php endif; ?>
But my variable is not output to the final value, the output string I get is this:
I tried before $reserve_price is a non-empty variable, but esc_html__() doesn't output the correct information to the page.
I am not quite sure about this reason.

"I tried before $reserve_price is a non-empty variable, but esc_html__() doesn't output the correct information to the page."
You can not use placeholders in esc_html__() function. It only retrieves the translation of a given text and escapes it for safe use in HTML output. Which means you could use it to:
- Escape html markups + translation
However, if you would need to:
- Escape html markups + translation + placeholder(s)
Then you could use the combination of esc_html, sprintf and __() functions, like so:
$test_value = '<strong>5.7<strong>';
echo esc_html(
sprintf(
__('This is a test for %s', 'your-text-domain'),
$test_value
)
)
Which will output this:
And if the provided text does not have any html tag(s), then it'd be something like this:
$test_value = 5.7;
echo esc_html(
sprintf(
__('This is a test for %s', 'your-text-domain'),
$test_value
)
)
Now, if we apply the same principles to your snippet, then it would be something like this:
<p class='reserve hold' data-auction-id='<?php echo esc_attr($product->get_id()); ?>'>
<?php
echo apply_filters(
'reserve_bid_text',
esc_html(
sprintf(
__('Reserve price has not been met, needed to enter $ %s or more', 'wc_simple_auctions'),
$reserve_price
)
)
);
?>
</p>
Let me know if you could get it to work!
