Wordpress Titles: If Longer Than 50 Characters, Show Ellipsis

I have a WordPress site with titles, and if the title has more than 50 characters I need to add an ellipsis (...) at the end of the title and stop the title at 50 characters.

Below is the PHP I am writing but it seems to not work 开发者_JAVA百科correctly.

<?php if (strlen("the_title()") > 50) { ?>
    <?php the_title(); ?>
<?php } if (strlen("the_title()") < 50) { ?>
    <?php echo substr(get_the_title(), 0, 50); ?>...
<?php } ?>

The mb_strimwidth function does exactly that.

echo mb_strimwidth(get_the_title(), 0, 50, '...');

WordPress has built in function "wp_trim_words()" to trim the sentences based on the number of words you provide, If you want to trim by words then this function may help you.

https://codex.wordpress.org/Function_Reference/wp_trim_words

to trim the title longer than 5 words you can do this

<?php
$title = get_the_title();
$short_title = wp_trim_words( $title, 5, '...' );
echo '<h3>'.$short_title.'</h3>';
?>

Single Code, 100% working

PHP Function mb_strimwidth() | Wordpress Function get_the_title()

<?php 
echo mb_strimwidth( get_the_title(), 0, 100, '...' ); 
?>

Add this to your "functions.php" file in your theme folder....

function the_title_excerpt($before = '', $after = '', $echo = true, $length = false) 
  {
    $title = get_the_title();

    if ( $length && is_numeric($length) ) {
        $title = substr( $title, 0, $length );
    }

    if ( strlen($title)> 0 ) {
        $title = apply_filters('the_title_excerpt', $before . $title . $after, $before, $after);
        if ( $echo )
            echo $title;
        else
            return $title;
    }
}

then call the title like as follows

<?php the_title_excerpt('', '...', true, '50'); ?>

You're checking the length of the string "the_title()". Remove the quotes, and it will probably work (I'm not 100% sure of the difference between the_title() and get_the_title(), as I haven't used Wordpress in a while -- you might have to switch that around too):

<?php if (strlen(the_title()) > 50) { ?>
                <?php the_title(); ?>
            <?php } if (strlen(the_title()) < 50) { ?>
                <?php echo substr(get_the_title(), 0, 50); ?>...
            <?php } ?>   

or maybe

<?php if (strlen(get_the_title()) > 50) { ?>
                <?php the_title(); ?>
            <?php } if (strlen(get_the_title()) < 50) { ?>
                <?php echo substr(get_the_title(), 0, 50); ?>...
            <?php } ?>

<?php 
$title  = the_title('','',false);
if(strlen($title) > 60):
    echo trim(substr($title, 0, 65)).'...';
else:
    echo $title;
endif;
?>

Take the_title() out of quotes when using the strlen() function.

---

echo (strlen(the_title())>50) ? (substr(the_title(), 0, 50) . "...") : the_title());

This is a ternary operator. What it basically says is if the result from the_title() is more than 50 characters, then echo the first 50 characters and then the string .... Otherwise, just echo the result from the_title().

You can read more about substr here: http://php.net/manual/en/function.substr.php

You can find info on the ternary operator here: http://php.net/manual/en/language.operators.comparison.php

use 'strlen'

eg: 

  <?php echo ((strlen(get_the_title())>50) ? (substr(get_the_title(), 0, 50) . "...") : get_the_title())?>
