我有一个“自定义插件”，用于抓取网站内容并通过简码放在我的网站上。在更新 wordpress 的 newset 版本（并切换到 HTTPS）后，短代码不起作用。

我试图打开其他主题，但没有帮助。

 <?php


 function file_get_contents_utf8($fn) {
 $content = file_get_contents($fn);
 $ary[] = "ISO-8859-2";
 $ary[] = "UTF-8";
 $ary[] = "ASCII";
return w1250_to_utf8($content);
/*return mb_convert_encoding($content, 'UTF-8',
      mb_detect_encoding($content,$ary, true));*/
 }

 function w1250_to_utf8($text) {
// map based on:
// http://konfiguracja.c0.pl/iso02vscp1250en.html
// http://konfiguracja.c0.pl/webpl/index_en.html#examp
// http://www.htmlentities.com/html/entities/
 $map = array(
    chr(0x8A) => chr(0xA9),
    chr(0x8C) => chr(0xA6),
    chr(0x8D) => chr(0xAB),
    chr(0x8E) => chr(0xAE),
    chr(0x8F) => chr(0xAC),
    chr(0x9C) => chr(0xB6),

    chr(0xBB) => '&raquo;',
     );
     if(strpos(get_permalink(),"eurojackpot") !== false)
    return $text;
   else
     return html_entity_decode(mb_convert_encoding(strtr($text, $map), 'UTF-8', 'ISO-8859-2'), ENT_QUOTES, 'UTF-8');
  }

 function download_tipos( $atts ) {
    $atts = shortcode_atts( array(
    'url' => '',
), $atts, 'download_tipos' );
    $content = file_get_contents_utf8($atts["url"]);
     if($atts["url"] == "http://eurojackpot.tipos.sk/sk/eurojackpot/vysledky"){
   preg_match('/(<div class="row".*?)<div id="footer"/s',$content,$vys);
 }
     else{
       preg_match('/(<div class="bgResultsPnlTop".*?)<div class="bgResultsPnlBottom"/s',$content,$vys);
  }

    $ret = str_replace('<div id="M5_pnlOptional1"',$reklama.'<div id="M5_pnlOptional1"',$vys[1]).$reklama2;
    $ret = str_replace('<div id="_7b7b0a087277_pnlOptional1"',$reklama.'<div id="_7b7b0a087277_pnlOptional1"',$ret);
    $ret = str_replace('<p class="kenoPlusNo"',$reklama.'<p class="kenoPlusNo"',$ret);
   $ret = str_replace('<div class="content col-md-6 right-col"',$reklama.'<div class="content col-md-6 right-col"',$ret);                 
  $ret = preg_replace('#<a.*?>.*?</a>#i', '', $ret);  
 $ret = preg_replace('#<img.*?>#i', '', $ret);  
  return $ret;  
}
 add_shortcode( 'download_tipos', 'download_tipos' );

 add_action('wp_head','hook_css');

 function hook_css() {?>
 <style>
  .orderedNumbers span,.unorderedNumbers span,.result-number li{
 border-radius: 50px;
 background-color: #eee;
 width: 50px;
 display: inline-block;
 text-align: center;
 font-size: 20px;
 }
 </style>
 <?php
 }
?>

在输出页面中有这个shortode：

  <p>[download_tipos url="http://www.tipos.sk/Default.aspx?CatID=711"] 
 </p>

我期望的是带有数字的表格，但我没有得到任何输出，并且在源代码中找不到的输出 URL（download_tipos 标记）。有没有办法调试这个问题？
