(Wordpress) How can i get the full content of a po

问题:

I'm using WordPress for my site with the qtranslate plugin and i'm trying to display language flags in each post.

Qtranslate inserts html tags to the content and title like "!--:en-->" for each language that i used in each post

So i need a conditional that checks which of these html tags are included in the content so i can print the specific flags

something like this:

function language_pick(){
    $qt_dir = "http://localhost/MY-SITE/wp-content/plugins/qtranslate-xp/flags/";
    $cr_url = "http://".$_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"];
    $en_url = esc_html($cr_url."&lang=en");
    $fr_url = esc_html($cr_url."&lang=fr");
    $it_url = esc_html($cr_url."&lang=it");
    $es_url = esc_html($cr_url."&lang=es");

    $query = get_post(get_the_ID()); 
    $content = apply_filters('the_content', $query->post_content);

    if(get_permalink() != $cr_url) { echo '<a style="margin-left:15px;" href="'.$cr_url.'" /><img src="'.$qt_dir.'gr.png"></a>'; }
    if (strpos($content, '<!--:en-->') === true) {
         if(get_permalink() != $en_url) { echo '<a style="margin-left:15px;" href="'.$en_url.'" /><img src="'.$qt_dir.'gb.png"></a>'; } }
    if(strpos($content,'<!--:fr-->') === true) {
        if(get_permalink() != $fr_url) { echo '<a style="margin-left:15px;" href="'.$fr_url.'" /><img src="'.$qt_dir.'fr.png"></a>'; } }
    if(strpos($content,'<!--:it-->') === true) {
        if(get_permalink() != $it_url) { echo '<a style="margin-left:15px;" href="'.$it_url.'" /><img src="'.$qt_dir.'it.png"></a>'; } }
    if(strpos($content,'<!--:es-->') === true) {
        if(get_permalink() != $es_url) { echo '<a style="margin-left:15px;" href="'.$es_url.'" /><img src="'.$qt_dir.'es.png"></a>'; } }
}

Very simply add <?= apply_filters('the_content', $content); ?>

There are loads of references to this on Google.

EDIT So in this case:

$query = get_post(get_the_ID()); 
$content = apply_filters('the_content', $query->post_content);

echo $content;
