[Chiuso] Translate dynamic string from a php variable

The plugin is this: link nascosto and the function where there is the string to translate is:
public function add_variable_price_fields($loop, $variation_data, $variation) {

$id = $variation->ID;

$read_only = '';
$is_disabled = apply_filters('woocom_urp_disable_urp_variation_fields', false, $variation);
if($is_disabled) {
$read_only = 'readonly="readonly"';
}

?>
<div class="clear"></div>
<div class="options_group">
<h3><?php _e('Custom Variation Prices:', 'woocom-urp'); ?></h3>
<?php
$count = 0;

foreach($this->custom_prices as $key => $name) {
$class = ++$count%2 ? "form-row-first":"form-row-last";
$price = WC_URP_Product_Meta::get_meta($variation, sanitize_key($key) );
$_field_price = wc_format_localized_price( $price );
$field_name = 'variable'.sanitize_key($key).'['.$loop.']';
?>
<p class="form-row <?php echo $class; ?>">
<label><?php echo esc_html(stripslashes($name)) . ' (' . get_woocommerce_currency_symbol() . ')'; ?> " href="#"> [?]</label>
<input type="text" size="5" name="<?php echo $field_name; ?>" value="<?php echo esc_attr( $_field_price ); ?>" class="wc_input_price" placeholder="<?php echo esc_html(stripslashes($name)); ?>" <?php echo $read_only; ?> />
</p>
<?php
}
do_action('woocom_urp_after_price_input_variable', $loop, $variation_data, $variation, $this->custom_prices);
echo '</div>';
}

Il problema è che la stringa esc_html(stripslashes($name)) $name non viene tradotta. In pratica dal backend creo un nuovo prezzo per i prodotti e questo nome che viene messo all'interno di $name vorrei tradurlo. Ho cercato nelle stringhe di amministrazione ma non viene fuori dopo aver applicato la seguente correzione:
esc_html__(stripslashes($name), 'textdomain')

ho provato cosi (ho dovuto togliere la word var altrimenti avevo un errore dato che questo ciclo è all'interno di una funzione/metodo di una classe):
foreach($this->custom_prices as $key => $name) {
$class = ++$count%2 ? "form-row-first":"form-row-last";
$price = WC_URP_Product_Meta::get_meta($variation, sanitize_key($key) );
$_field_price = wc_format_localized_price( $price );
$field_name = 'variable'.sanitize_key($key).'['.$loop.']';
$contentName = stripslashes($name);
?>
<p class="form-row <?php echo $class; ?>">

<label><?php sprintf( __($contentName, 'woocom-urp') . ' (' . get_woocommerce_currency_symbol() . ')'); ?> " href="#"> [?]</label>
<input type="text" size="5" name="<?php echo $field_name; ?>" value="<?php echo esc_attr( $_field_price ); ?>" class="wc_input_price" placeholder="<?php echo esc_html(stripslashes($name)); ?>" <?php echo $read_only; ?> />
</p>
<?php
}

ma non va, la stringa viene ignorata.

hi, i found the problem. I forgot to delete a string in my custom plugin Kootj_plugin at line 305
