(Wordpress) How can i get the full content of a post with the html tags - unstripped

Question

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>'; } }
}

Answer 1

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;
