full articles list (no readmore or link title

it will be useful to have the possibility to show full content articles or just a part I did it in that way :

in wp-config.php — > define('SHOW_CONTENT', 1);

in the pages displaying content –>

<?php
    if(SHOW_CONTENT == 1){
    echo '<div class="entry-content">';
    the_content();
    }
    else{
    echo '<div class="entry-summary">';
    the_excerpt( __( 'Continue reading <span class="meta-nav">→</span>', 'ymages' ) );
    }
    ?>
    </div>
