Есть код
<div class="simplecheckout-button-block buttons" id="buttons">
<div class="simplecheckout-button-right">
<?php if ($display_agreement_checkbox) { ?>
<span id="agreement_checkbox">
<?php foreach ($text_agreements as $agreement_id => $text_agreement) { ?>
<div class="checkbox"><label><input type="checkbox" name="agreements[]" value="<?php echo $agreement_id ?>" <?php echo in_array($agreement_id, $agreements) ? 'checked="checked"' : '' ?> /><?php echo $text_agreement; ?></label></div>
<?php } ?>
</span>
<?php } ?>
<?php if ($steps_count > 1) { ?>
<a class="button btn-primary button_oc btn" data-onclick="nextStep" id="simplecheckout_button_next"><span><?php echo $button_next; ?></span></a>
<?php } ?>
<a class="button btn-primary button_oc btn" <?php echo $block_order ? 'disabled' : '' ?> data-onclick="createOrder" id="simplecheckout_button_confirm"><span><?php echo $button_order; ?></span></a>
</div>
<div class="simplecheckout-button-left">
<?php if ($display_back_button) { ?>
<a class="button btn-primary button_oc btn" data-onclick="backHistory" id="simplecheckout_button_back"><span><?php echo $button_back; ?></span></a>
<?php } ?>
<?php if ($steps_count > 1) { ?>
<a class="button btn-primary button_oc btn" data-onclick="previousStep" id="simplecheckout_button_prev"><span><?php echo $button_prev; ?></span></a>
<?php } ?>
</div>
</div>
Результат выполнения нужно вставить сюда
$replace = array(
'{right_column}' => '<div class="simplecheckout-right-column">',
'{/right_column}' => '<b>!!!!!!!!!!!!СЮДА !!!!!!!!!!!!!!! </b></div>',
);
Как это сделать?
