<?php

$tarih = explode('T', $order->get_date_completed());
$now = date("Y-m-d");
$origin = date_create($tarih[0]);
$target = date_create($now);
$interval = date_diff($origin, $target);
$iade_hakki=$interval->d;
$aide_yazi='';
?>
  <section class="woocommerce-columns woocommerce-columns--2 woocommerce-columns--addresses col2-set addresses">
    <div class="woocommerce-column woocommerce-column--1 woocommerce-column--billing-address col-1">
        <?php
        global $wp;
          $current_url = home_url(add_query_arg(array(), $wp->request));
        if ($order->get_status()=="completed") {
            if ($iade_hakki>=14){ ?>
            <?php } else{?>
                <button id="button-iade" data-id="<?=$order_id?>" style="border-radius: 4px;border:1px solid #92cecc; background-color: white;color:#92cecc" data-redirect="<?=$current_url?>" class="woocommerce-Button button woocommerce-column__title" >
                    Siparişi İade Et </button>
            <?php  }
        }
        elseif ($order->get_status()=='shipped'){ ?>

            <button id="button-iade" style="border-radius: 4px;border:1px solid #92cecc; background-color: white;color:#92cecc" data-id="<?=$order_id?>" data-redirect="<?=$current_url?>" class="woocommerce-Button button woocommerce-column__title" >

        <?php }
        else if ($order->get_status() == 'processing' || $order->get_status() == 'on-hold') {
            global $wp;
            $current_url = home_url(add_query_arg(array(), $wp->request));

            ?>

            <button id="button-iptal" style="border-radius: 4px;border:1px solid #92cecc; background-color: white;color:#92cecc" data-id="<?=$order_id?>" data-redirect="<?=$current_url?>" class="woocommerce-Button button woocommerce-column__title" >

        <?php } else{
            echo '';
