I ran into this problem So I am adding custom fields for the Spanish Content and switching it in the functions file. (See below)
Only problem is I can’t get the title to work right.
Here is my forum question about this issue:
https://www.ads-software.com/support/topic/adding-filter-to-the-title?replies=1
//spanish content
if(find_language()=='es'){
add_filter('the_content','spanish_content');
add_filter('the_title','spanish_title');
}
function find_language(){
if($_GET['lan']=='es'){
setcookie("lantnd", 'es', time()+3600, "/", str_replace('https://www','',get_bloginfo('url')) );
$lan='es';
//echo __LINE__;
}
else if($_GET['lan']=='en'){
setcookie("lantnd", 'en', time()+3600, "/", str_replace('https://www','',get_bloginfo('url')) );
$lan='en';//echo __LINE__;
}
else if($_COOKIE['lantnd']=='en'){
$lan='en';//echo __LINE__;
}
else if($_COOKIE['lantnd']=='es'){
$lan='es';//echo __LINE__;
}
else {
$lan='en';//echo __LINE__;
//echo "COOKIE "; print_r($_COOKIE);
}
return $lan;
}
function spanish_content($content){
global $post;
$spanish=get_post_meta(get_the_id(), 'spanish_content');
$span= $spanish[0];
if(!$span){
$span='<p><em>Spanish translation is not available.</em></p>'.$content;
}
return $span;
}
function spanish_title($title){
$spanish=get_post_meta(get_the_id(), 'spanish_title');
$span= $spanish[0];
if(strlen($span)<1){
return $title;
}
return $span;
}
