I am costuming a template. There is a list grabbing the introduction from the first 1-2 paragraphs (all the articles from a category). If I set the excerpt to 295 words, sometimes the list grabs additional words from the next paragraph. I would like to add a Read More tag to stop it. Can someone help me with that part?

<div id="all-div-cabrand-content-stories">
    <div class="kids-families-con-cabrand-stories">
        <?php echo get_the_post_thumbnail($page->ID, 'thubmnailstorysmall'); ?>
    </div>
    <div class="kids-con-cabrand-new-stories">
        <span>
            <?php print substr(get_the_excerpt(),wp_trim_excerpt(),295); ?>
            <i><a style="color:#1975D1;float:Right;" class="title" href="<?php the_permalink() ?>" rel="bookmark">Click for Story & Video</a></i>
            <br/>
        </span>
    </div>
</div>

You can grab the first one or two paragraphs with a regular expression (regexp)

function custom_excerpt( $content = '' ){

    if( empty( $content ) )
        return $content;

    $result = '';
    $matches = array();

    // grab all paragraphs from $content
    preg_match_all( '#<\s*p[^>]*>(.*?)<\s*/\s*p>#ui', $content, $matches );

    if( ! empty( $matches ) ){

        // add the first paragraph
        $result = $matches[0][0];

        // add the swecond paragraph if available
        if( isset( $matches[0][1] ) )
            $result .= $matches[0][1];

        // set the excerpt length
        add_filter( 'excerpt_length', 'custom_excerpt_length' );

        // create the custom excerpt
        $result = custom_trim_excerpt( $result );

    }

    return $result;

}

function custom_excerpt_length(){

    return 295;

 }

function custom_trim_excerpt( $text = '' ){

    $text = strip_shortcodes( $text );

    $text = apply_filters('the_content', $text);
    $text = str_replace(']]>', ']]&gt;', $text);
    $excerpt_length = apply_filters('excerpt_length', 55);
    $excerpt_more = apply_filters('excerpt_more', ' ' . '[...]');
    $text = wp_trim_words( $text, $excerpt_length, $excerpt_more );

    return $text;
}

Call the function with

<?php print custom_excerpt( get_the_content( 'Read More' ) ); ?>

This is a bit tricky because you can not hand over wp_trim_excerpt() a text. wp_trim_excerpt() will simply return the text if one is given. You have to copy and customize the function a bit.

To get a specific length you can use: wp_trim_words function. It has 3 parameters.

  1. Text to trim. Ex: get_the_content()
  2. Number of words. Ex: 295
  3. What to append after end of the text. Ex: '' This means null.

Use this:

<span>
    <?php echo wp_trim_words( get_the_content(), 295, '' ); ?>
    <i><a style="color:#1975D1;float:Right;" class="title" href="<?php
        the_permalink() ?>" rel="bookmark">Click for Story & Video</a></i>
    <br/>
</span>

You can use this function:

function get_excerpt_trim($num_words='20', $more='...'){
    $excerpt = get_the_excerpt();
    $excerpt = wp_trim_words( $excerpt, $num_words , $more );
    return $excerpt;
}

To get what you want you need to do two things.

1) Establish a custom excerpt length (in words, not characters), best achieved by following this answer.

2) Just call wp_trim_excerpt(), don't wrap it inside of substr

Your line of code above is not doing what you are expecting it to do. I believe it's returning the first 295 characters of the excerpt, but I'm not fully sure of what the php subtr() function is going to do when you pass it a string as the second argument when it's expecting an integer.

You can use the built in function

function custom_excerpt_length( $length ) {
    return 20;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
