Question

我正在使用带有qTranslate和自定义主题的wordpress。主题带来自动完成搜索。我的问题是帖子/页面标题没有翻译。我检查了stackoverflow / google，似乎存在AJAX请求和qTranslate的问题。这就是为什么我在我的php文件的url参数中添加了以下内容：

?lang='.qtrans_getLanguage()

我检查了控制台，并且参数正确传递（对于每种语言）到javascript文件。我现在需要的是读取这个url参数并将其返回到我的php文件（我在使用lang=en时测试了js文件并将$.getJSON添加到url并且它有效但我需要传递的语言）。

PHP

<?php

    add_action( 'init', 'myprefix_autocomplete_init' );  
    function myprefix_autocomplete_init() {  
        // Register our jQuery UI style and our custom javascript file  
        wp_register_script( 'my_acsearch', get_template_directory_uri() . '/nectar/assets/functions/ajax-search/wpss-search-suggest.js?lang='.qtrans_getLanguage(), array('jquery','jquery-ui-autocomplete'),null,true);  
        wp_localize_script( 'my_acsearch', 'MyAcSearch', array('url' => admin_url( 'admin-ajax.php' ))); 

        // Function to fire whenever search form is displayed  
        add_action( 'get_search_form', 'myprefix_autocomplete_search_form' );  

        // Functions to deal with the AJAX request - one for logged in users, the other for non-logged in users.  
        add_action( 'wp_ajax_myprefix_autocompletesearch', 'myprefix_autocomplete_suggestions' );  
        add_action( 'wp_ajax_nopriv_myprefix_autocompletesearch', 'myprefix_autocomplete_suggestions' );  
    }  

    function myprefix_autocomplete_search_form(){  
        wp_enqueue_script( 'my_acsearch' );  
    }  

    add_action( 'wp_ajax_{action}', 'my_hooked_function' );

        position: {of: "#search-outer #search .container" },

            window.location.href=ui.item.link;  
        },  
        minLength: 2,  
    }).data( "ui-autocomplete" )._renderItem = function( ul, item ) {
        return $( "<li>" )
        .append( "<a>" + item.image + "<span class='title'>" + item.label + "</span><br/><span class='desc'>" + item.post_type + "</span> </a>" )
        .appendTo( ul );
    };  

});

我希望有人可以帮助我

Answer 1

即使这不是一个好的解决方案，我想出了这个：

var lang;

$('script').each(function(i, e) {
    var scriptName = $(e).attr('src');

    if(typeof scriptName != 'undefined') {
        if(scriptName.indexOf('wpss-search-suggest') != -1) {
            lang = scriptName.substr(scriptName.lastIndexOf('=')+1, scriptName.length-1);
        }
    }
});  

$.getJSON(MyAcSearch.url+'?callback=?&lang='+lang+'&action='+acs_action, req, response);

Answer 2

我发现了一个更简单的解决方法，但有条件的php是必要的（使用条件码在php文件中硬编码脚本）：

而不是：

window.location.href=ui.item.link;

您可以使用：

var lang = '<?php echo qtrans_getLanguage(); ?>';
window.location.href=ui.item.link+'?lang='+lang;

所以脚本是（我还包括另一个检查qTranslate是否被激活的条件）：

  //
  // Autocomplete Searchform
  var acs_action = 'myprefix_autocompletesearch';
  jQuery("#s").autocomplete({
      delay: 50,
      position: {of: "#search-outer #search .container" },
      appendTo: $("#search-box"), 
      source: function(req, response){
          jQuery.getJSON(MyAcSearch.url+'?callback=?&action='+acs_action, req, response);
      },
      select: function(event, ui) {
<?php if (function_exists('qtrans_getLanguage')){ ?>
          var lang = '<?php echo qtrans_getLanguage(); ?>';
          window.location.href=ui.item.link+'?lang='+lang;
<?php }else{ ?>
          window.location.href=ui.item.link;
<?php } ?>
      },
      minLength: 2,
    }).data( "ui-autocomplete" )._renderItem = function( ul, item ) {
        return jQuery( "<li>" )
        .append( "<a>" + item.image + "<span class='title'>" + item.label + "</span></a>" )
        .appendTo( ul );
    };
