Get and Trim Full Publish Content material in WP Question

Easy job, but it surely is not working:

<?php 
$content material = apply_filters( 'the_content', get_the_content() );
$contentWithoutHTML = wp_strip_all_tags($content material);
$pos = strpos($contentWithoutHTML, " ", 100);
$contentFinal = substr($contentWithoutHTML,0,$pos ); 
echo $contentFinal . "...";
?>

My put up is manner over 100 characters lengthy (with areas), and but I get strpos(): Offset not contained in string error, which leads me to consider it is not really pulling the whole content material string. However I utilized filters like I consider I ought to… please help. Additionally typically even when I get no offset error I simply get ... although once more, over 100 characters with areas… though typically it really works. Why the inconsistency?

That is in a WP_Query loop through which most of them work, however a few of them don’t… so I’m fairly positive it’s being fed a string as a result of I see it occurring to the opposite posts within the loop…

Full Loop:

<?php
$args = array(
    'orderby' => 'ID',
    'order' => 'ASC',
    'posts_per_page' => 7,
    'meta_query' => array(
        array(
            'key' => '_thumbnail_id'
        )
    )
);
$question = new WP_Query($args);
whereas ($query->have_posts()):
    $query->the_post();
?>
                            <div class="articleboxs boxs">
                                <div class="col-sm-4 noleft">

                                      <?php the_post_thumbnail('medium', array(
        'class' => 'img-responsive'
    )) ?>  
                                    </div>
                                </div>

                                                <?php

                                    </div>
                                </div>
                            </div>
                          <?php
