Remove words from the_excerpt_rss() with php

    I have followed this tutorial : https://www.wpbeginner.com/wp-tutorials/how-to-create-custom-rss-feeds-in-wordpress/ to create a custom feed.

    The main objective is to create a new feed that will not have the two words “Photo Credits” that are present in each item’s excerpt of the regular WordPress RSS feed.

    So I thought in my custom feed template I could use something like:

    <?php
    $excerptWithoutCredits=the_excerpt_rss();
    $excerptWithoutCredits=str_replace('Photo Credits', '', $excerptWithoutCredits);
?>

    and then:

    <description><![CDATA[<?php echo $excerptWithoutCredits;  ?>]]></description>

    but this is not working, nothing is displayed. It looks like I can’t retrieve the_excerpt_rss() in a variable?

    How can I do exactly to remove those two words from the_excerpt_rss() ?
    Thanks

    try to use a filter function, added in functions.php of your (child) theme;

    example code:

    add_filter( 'the_excerpt_rss', 'remove_words_from_excerpt_rss' );
function remove_words_from_excerpt_rss( $output ) {
    $output = str_replace('Photo Credits', '', $output);
    return $output;
}

    that’s great, it works! Do you know if I can apply this filter only to my custom feed, and not to the regular WordPress feed?

    Is the only way to do that to create another function the_excerpt_rss2() and use that in my custom feed template?

    if I can apply this filter only to my custom feed, and not to the regular WordPress feed?

    try and replace line 35 of the template code in your linked tutorial:

    <description><![CDATA[<?php the_excerpt_rss() ?>]]></description>

    with:

    <description><![CDATA[<?php add_filter( 'the_excerpt_rss', 'remove_words_from_excerpt_rss' ); the_excerpt_rss(); remove_filter( 'the_excerpt_rss', 'remove_words_from_excerpt_rss' ); ?>]]></description>

    and in functions.php of the (child) theme, use only:

    function remove_words_from_excerpt_rss( $output ) {
    $output = str_replace('Photo Credits', '', $output);
    return $output;
}
