post_title: replace special chars like ??ü in wordpress title

  • There is a static webpage on which the recent wp posts should be displayed. I cannot change the encoding of that webpage. I’m trying to help a friend in germany who has run into serious problems with german Umlaute as he calls it.

    Whenever I try to pull the posts:

      <?php
    $recent_posts = wp_get_recent_posts(array(
        'numberposts' => 4, // Number of recent posts thumbnails to display
        'post_status' => 'publish' // Show only the published posts
    ));
    foreach( $recent_posts as $post_item ) : ?>
        <p><a href="<?php echo get_permalink($post_item['ID']) ?>"><?php echo $post_item['post_title'] ?>
            </a><br/><?php $post_date = get_the_date( 'd.m.Y' ); echo $post_date;?></p>
           <?php endforeach; ?>

    I end up with messed up titles as long as the post title contains special chars like ??ü.

    I had no luck with preq replace. Not sure if I did anything wrong.

    So how could we get rid of this stupid special chars and replace them with html entities?

    Can you paste the corresponding part into the code snippet that I’ve pasted above please?

    I don’t really know where and how the encoding should take place with out breaking anything. I end up getting fatal wordpress errors.

    You have echo $post_item['post_title']
    when you could use echo htmlentities(strip_tags($post_item['post_title']))
    but you should read the PHP page I mentioned to determine the correct values for the flags and encoding parameters for your situation.

    Your code is a little “off” with the date.
    You are calling $post_date = get_the_date( 'd.m.Y' );
    https://developer.www.ads-software.com/reference/functions/get_the_date/
    This will get the date from the current post, not the one that you retrieved with wp_get_recent_posts. You need to pass in the post ID.

    The replacing now works like a charm now but I really had issues to display the date related to the individual posts.

    However, thanks to @joyously and some trial and error I came up with this code snippet that works as intended.

    Is there still any mistake in the code?

      <?php
    $recent_posts = wp_get_recent_posts(array(
        'numberposts' => 10, // Number of recent posts thumbnails to display
        'post_status' => 'publish' // Show only the published posts
    ));
    foreach( $recent_posts as $post_item ) : ?>
        <p><a href="<?php echo get_permalink($post_item['ID']) ?>"><?php echo htmlentities(strip_tags($post_item['post_title']))?>
			</a><br/>
			<?php $post_date = get_the_date( 'd.m.Y', $post_item['ID'] ); echo $post_date;?></p>
           <?php endforeach; ?>
