(first of all i'm new with php)
i have a wordpress blog where i have written about some ppl and i added their names as tags in a costum taxonomy to avoid multi language field with polylang.
I was looking for a loop that allow to show, for every tag, the title of post where tag exist.
Example => post's name: "what a chef can do?" (tagged Alex P.)
result: -Alex P. "what a chef can do?" 05/10/2020 - "Tomatos in the world" 15/12/2020.
For every person(tag) i have to make an Accordion.

i've started to write code but i'm not looking for a solution and i'm getting lost.

<?php $tag_args = array(

'orderby' => 'title',

'order' => 'ASC'    

);

?>

<ul id="Genre-List">

<li>DEFAULT</li>

<?php

$terms = get_terms(

array(

    'taxonomy'   => 'chef',

    'hide_empty' => false,

)

);

// Check if any term exists

if ( ! empty( $terms ) && is_array( $terms ) ) {

// Run a loop and print them all

    print_r($terms);

foreach ( $terms as $term ) { 

        

?>

    <li><a href="<?php echo esc_url( get_term_link( $term ) ) ?>">

        <?php echo $term->name; ?>

    </a></li>

<?php

}

}

?>

Thanks if anyone can help about this.. im really getting mad.

My Answer:
php
$tags = get_terms( array(
'taxonomy' => 'post_tag',
'hide_empty' => false,
) );

foreach ( $tags as $tag ) {
$args = array(
'post_type' => 'post',
'posts_per_page' => -1,
'tax_query' => array(
array(
'taxonomy' => 'post_tag',
'field' => 'slug',
'terms' => $tag->slug,
),
),
);

$query = new WP_Query( $args );

if ( $query->have_posts() ) {
echo '

' . $tag->name . '

';
echo '

';
while ( $query->have_posts() ) {
$query->the_post();
echo '
• ' . get_the_title() . '
';
}
echo '

';
}

wp_reset_postdata();
}
?>


This code will retrieve all tags from the 'post_tag' taxonomy and then loop through each tag to display the title of posts that have that tag. It will display the tag name as a heading and then list the titles of the posts under that tag.
