替换多个字符串或文本

Question

如果您必须在任何页面中替换或翻译functions.php中的一个字符串或文本，那么这段代码在WordPress中工作得很好：

//The filters.. both are required.
add_filter('gettext', 'change_cancellation_btn');
add_filter('ngettext', 'change_cancellation_btn');

//function
function change_cancellation_btn($cancellation_btn){
$cancellation_btn = str_ireplace('text to replace', 'new text', $cancellation_btn);
return $cancellation_btn;
}

如何使用相同的代码替换多个字符串或文本？

在我的例子中，我用两个不同的按钮替换了文本，为了做到这一点，我使用了两次相同的代码：

//The filters.. both are required.
add_filter('gettext', 'change_cancellation_btn');
add_filter('ngettext', 'change_cancellation_btn');

//function button 1
function change_cancellation_btn($cancellation_btn){
$cancellation_btn = str_ireplace('text 1 to replace', 'new text 1', $cancellation_btn);
return $cancellation_btn;
}


//The filters.. both are required.
add_filter('gettext', 'change_nocancellation_btn');
add_filter('ngettext', 'change_nocancellation_btn');

//function button 2
function change_nocancellation_btn($nocancellation_btn){
$nocancellation_btn = str_ireplace('text 2 to replace', 'new text 2', $nocancellation_btn);
return $nocancellation_btn;
}

那么，有办法用一个函数替换多个字符串吗？

Answer 1

您可以使用如下所示的开关情况：

add_filter( 'gettext', 'theme_change_comment_field_names', 20, 3 );
function theme_change_comment_field_names( $translated_text, $text, $domain ) {
  
    switch ( $translated_text ) {
 
        case 'text 1 to replace' :
 
            $translated_text = __( 'new text 1', 'theme_text_domain' );
            break;
 
        case 'text 2 to replace' :
 
            $translated_text = __( 'new text 2', 'theme_text_domain' );
            break;
    }    
 
    return $translated_text;
}

还没测试过。

Call the function inside the loop
and pass the parameter by creating an array or if you from a database similar its work.

e.g:
$array = array(
array(
'text_to_replace' => 'Dummy',
'new_text' => 'Test',
'text_content'=> 'Dummy content string'
))

//function
function change_cancellation_btn($text_to_replace, $new_text, $text_content){
$changedText = str_ireplace($text_to_replace, $new_text, $text_content);
return $changedText;
}


Now call the change_cancellation_btn by running the loop of the array by passing multiple contents.

最新消息。这对我来说更好，因为它也替换/翻译了管理后端中的所有字符串：

add_filter(  'gettext',  'dirty_translate'  );
add_filter(  'ngettext',  'dirty_translate'  );
function dirty_translate( $translated ) {
     $words = array(
            // 'word to translate' => 'translation'
            'Dashboard' => 'Foo',
            'Add new' => 'Bar'
     );
$translated = str_ireplace(  array_keys($words),  $words,  $translated );
return $translated;
}
