动态覆盖幻想标题-第二部分

时间：2017-04-13 作者：Monica Maria Crapanzano

我按照pat-j和cjbj的指示回答：Dynamically Override Fancy Title 我得到了覆盖标题的结果。现在我需要动态更改此标题。我编写了此函数：

add_filter (\'presscore_get_page_title\',\'netbooking_presscore_get_page_title\',10,1);
function netbooking_presscore_get_page_title ( $title ) {

if(  is_page( \'1057\' ) ){

    $GLOBALS["content"] = $content;
//如果出现错误，则读取输入时考虑默认值

$INPUT = function($param, $default, $prefix = true){
            $key = $prefix ? \'netbooking_structure_\'.$param : $param;
            return isset($GLOBALS["content"][$key]) ? $GLOBALS["content"][$key] : $default;
        };
//此读取获取输入

$language = $INPUT(\'language\', \'it\', false);
        $lang = substr($language, 0, 2);
        $upwd = $INPUT(\'upwd\', \'8UDW37tF\', false);
        $cryptedID = $INPUT(\'crypted_id\', \'Nel6LjH9xZ4=\', false);
        $structure_id = $INPUT(\'sid\', 268, false);
        $accomodation_id = $INPUT(\'aid\', \'4894\', false);
//调用并获取包含住宿数据的XML

$today = getdate();
        $api = \'http://url\';
        $query = http_build_query([
            \'get\' => \'getaccomodation\',
            \'upwd\' => $upwd,
            \'id\' => $structure_id,
            \'idacc\' => $accomodation_id,
            \'type\' => \'p\',
            \'mode\' => \'xml\',
            \'ukey\' => \'create\',
            \'l\' => $lang,
            \'dstart\' => $today[\'mday\'],
            \'mstart\' => $today[\'mon\'],
            \'ystart\' => $today[\'year\'],
        ]);
        $xml = new SimpleXMLElement(file_get_contents($api. \'?\' . $query));
        $accomodation = $xml->accomodation;
    // Ottengo l\'XML del prezzo della accomodation
    $api = \'http://netbooking.naturalbooking.it/getnbdata.php\';
    $query = http_build_query([
        \'get\' => \'accomodationminprice\',
        \'upwd\' => $upwd,
        \'id\' => $structure_id,
        \'idacc\' => $accomodation_id,
        \'type\' => \'p\',
        \'mode\' => \'xml\',
        \'ukey\' => \'create\',
        \'l\' => $lang,
    ]);
    $priceData = new SimpleXMLElement(file_get_contents($api. \'?\' . $query));
//这里有当前住宿的链接

$link = \'http://url\';
        $query = http_build_query([
            \'cmd\' => \'bookstep1\',
            \'id\' => $cryptedID,
            \'type\' => \'p\',
            \'l\' => $lang,
            \'idacc\' => $accomodation_id
        ]);
        $link = $link. \'?\' . $query;
//本地设置

setlocale(LC_TIME, $language);
//获取标题

    $accomodation->id;
    if ($accomodation){

          foreach($accomodation as $accomodation) {
         $title = $accomodation->name_struct." ".$accomodation->name;
         }
         }
    }   
  return $title;
         }
它总是返回列表中第一个住宿的名称，而不是当前住宿的名称。

EDIT我确定问题在get函数内部。但我不明白为什么页面模板中的相同内容可以工作，而在挂钩中却不起作用。这是函数的最新版本：

// ACCOMODATION TITLE
add_filter (\'presscore_get_page_title\',\'netbooking_presscore_get_page_title\',10,1); // filtro che aggiunge la funzione per sovrascrivere il title
function netbooking_presscore_get_page_title ( $title ) { // title function
if(  is_page( \'1057\' ) ){ // conditional output

        global $content;
        $GLOBALS["content"] = $content;

        // This reads input considering a default value in case of error

        $INPUT = function($param, $default, $prefix = true){
            $key = $prefix ? \'netbooking_structure_\'.$param : $param;
            return isset($GLOBALS["content"][$key]) ? $GLOBALS["content"][$key] : $default;
        };

        // Read GET input
        $language = $INPUT(\'language\', \'it\', false);
        $lang = substr($language, 0, 2);
        $upwd = $INPUT(\'upwd\', \'8UDW37tF\', false);
        $cryptedID = $INPUT(\'crypted_id\', \'Nel6LjH9xZ4=\', false);
        $structure_id = $INPUT(\'sid\', 268, false);
        $accomodation_id = $INPUT(\'aid\', \'4894\', false);

        // Build XML Accomodation
        $today = getdate();
        $api = \'http://myurl.it\';
        $query = http_build_query([
            \'get\' => \'getaccomodation\',
            \'upwd\' => $upwd,
            \'id\' => $structure_id,
            \'idacc\' => $accomodation_id,
            \'type\' => \'p\',
            \'mode\' => \'xml\',
            \'ukey\' => \'create\',
            \'l\' => $lang,
            \'dstart\' => $today[\'mday\'],
            \'mstart\' => $today[\'mon\'],
            \'ystart\' => $today[\'year\'],
        ]);
        $xml = new SimpleXMLElement(file_get_contents($api. \'?\' . $query));

        // Imposto il locale
        setlocale(LC_TIME, $language);



$nomestruttura=(string)$xml->accomodation->name_struct;
$nome=(string)$xml->accomodation->name;

$title=$nomestruttura." ".$nome;

    }   
  return $title;
         }

我终于明白了。该函数的最终版本为：

<?php 

// ACCOMODATION TITLE
add_filter (\'presscore_get_page_title\',\'netbooking_presscore_get_page_title\',10,1);
function netbooking_presscore_get_page_title ( $title ) {
if(  is_page( \'1057\' ) ){

        $GLOBALS["content"] = $content;

        // This reads input considering a default value in case of error


$INPUT = function($param, $default, $prefix = true){
                $key = $prefix ? \'netbooking_structure_\'.$param : $param;
                return isset($GLOBALS["content"][$key]) ? $GLOBALS["content"][$key] : $default;
            };

        // Read input GET
        $language = $INPUT(\'language\', \'it\', false);
        $lang = substr($language, 0, 2);
        $upwd = $INPUT(\'upwd\', \'8UDW37tF\', false);
        $cryptedID = $INPUT(\'crypted_id\', \'Nel6LjH9xZ4=\', false);
        $structure_id = $INPUT(\'sid\', 268, false);
        $accomodation_id = $INPUT(\'aid\', \'4894\', false);

        // XML accomodation
        $today = getdate();
        $api = \'http://\';
        $query = http_build_query([
            \'get\' => \'getaccomodation\',
            \'upwd\' => $upwd,
            \'id\' => $structure_id,
            \'idacc\' => $accomodation_id,
            \'type\' => \'p\',
            \'mode\' => \'xml\',
            \'ukey\' => \'create\',
            \'l\' => $lang,
            \'dstart\' => $today[\'mday\'],
            \'mstart\' => $today[\'mon\'],
            \'ystart\' => $today[\'year\'],
        ]);
        $xml = new SimpleXMLElement(file_get_contents($api. \'?\' . $query));



        // Imposto il locale
        setlocale(LC_TIME, $language);

 $url="htp://";

$xml = simplexml_load_file($url);

$nomestruttura=(string)$xml->accomodation->name_struct;
$nome=(string)$xml->accomodation->name;

$title=$nomestruttura." ".$nome;

    }   
  return $title;
         }
         ?>
我理解错误在于获取xml的函数中。现在我必须解决这个问题。EDIT & SOLVED

    // ACCOMODATION TITLE
add_filter (\'presscore_get_page_title\',\'netbooking_presscore_get_page_title\',10,1); // filter for title
function netbooking_presscore_get_page_title ( $title ) { // function to override title
if(  is_page( icl_object_id(\'1057\')) ){ // Conditional output with ICL support
// Added Query 

                global $wp_query; 

    // Get Values
    $content = [];
    $content["crypted_id"] =   get_option(\'netbooking_\'.\'home\'.\'_crypted_id_meta\');
    $content["upwd"] =         get_option(\'netbooking_\'.\'home\'.\'_upwd_meta\');
    $content["structure_id"] = get_option(\'netbooking_\'.\'home\'.\'_structure_id_meta\');
    $content["language"] = netbooking_get_language();
    $content["sid"] = isset($_GET[\'sid\']) ? $_GET[\'sid\'] : $wp_query->query_vars[\'sid\'];
    $content["aid"] = isset($_GET[\'aid\']) ? $_GET[\'aid\'] : $wp_query->query_vars[\'aid\'];
    foreach ($GLOBALS[\'structure\'.\'-options\'] as $key => $option) {
        $content[$key] = get_option($key);
}


        $GLOBALS["content"] = $content;

        // Function to read default values in case of error
        $INPUT = function($param, $default, $prefix = true){
            $key = $prefix ? \'netbooking_structure_\'.$param : $param;
            return isset($GLOBALS["content"][$key]) ? $GLOBALS["content"][$key] : $default;
        };

        // GET Input
        $language = $INPUT(\'language\', \'it\', false);
        $lang = substr($language, 0, 2);
        $upwd = $INPUT(\'upwd\', \'8UDW37tF\', false);
        $cryptedID = $INPUT(\'crypted_id\', \'Nel6LjH9xZ4=\', false);
        $structure_id = $INPUT(\'sid\', 268, false);
        $accomodation_id = $INPUT(\'aid\', \'4894\', false);

        // Accomodation XML 
        $today = getdate();
        $api = \'http://myurl.it\';
        $query = http_build_query([
            \'get\' => \'getaccomodation\',
            \'upwd\' => $upwd,
            \'id\' => $structure_id,
            \'idacc\' => $accomodation_id,
            \'type\' => \'p\',
            \'mode\' => \'xml\',
            \'ukey\' => \'create\',
            \'l\' => $lang,
            \'dstart\' => $today[\'mday\'],
            \'mstart\' => $today[\'mon\'],
            \'ystart\' => $today[\'year\'],
        ]);
        $xml = new SimpleXMLElement(file_get_contents($api. \'?\' . $query));

        // Imposto il locale
        setlocale(LC_TIME, $language);


$nomestruttura=(string)$xml->accomodation->name_struct;
$nome=(string)$xml->accomodation->name;

$title=$nomestruttura." ".$nome;

    }   
  return $title;
         }
这终于奏效了！
