WordPress tip: move all JavaScript files to the footer automatically

In order to improve the loading time of your WordPress blog, it is recommended that you move JavaScript files to the bottom of your HTML documents. Unfortunately, it isn’t always as easy as it seems, especially when using some plugins who inject code in the header. Here’s a simple solution to automatically move all JavaScript files to the bottom.

First, open your functions.php file and paste the following code in it:

/**
 * Filter HTML code and leave allowed/disallowed tags only
 *
 * @param string 	$text 	Input HTML code.
 * @param string 	$tags 	Filtered tags.
 * @param bool 		$invert Define whether should leave or remove tags.
 * @return string Filtered tags
 */
function theme_strip_tags_content($text, $tags = '', $invert = false) {

    preg_match_all( '/<(.+?)[\s]*\/?[\s]*>/si', trim( $tags ), $tags );
    $tags = array_unique( $tags[1] );

    if ( is_array( $tags ) AND count( $tags ) > 0 ) {
        if ( false == $invert ) {
            return preg_replace( '@<(?!(?:'. implode( '|', $tags ) .')\b)(\w+)\b.*?>.*?</\1>@si', '', $text );
        }
        else {
            return preg_replace( '@<('. implode( '|', $tags ) .')\b.*?>.*?</\1>@si', '', $text );
        }
    }
    elseif ( false == $invert ) {
        return preg_replace( '@<(\w+)\b.*?>.*?</\1>@si', '', $text );
    }

    return $text;
}

/**
 * Generate script tags from given source code
 *
 * @param string $source HTML code.
 * @return string Filtered HTML code with script tags only
 */
function theme_insert_js($source) {

    $out = '';

    $fragment = new DOMDocument();
    $fragment->loadHTML( $source );

    $xp = new DOMXPath( $fragment );
    $result = $xp->query( '//script' );

    $scripts = array();
    $scripts_src = array();
    foreach ( $result as $key => $el ) {
        $src = $result->item( $key )->attributes->getNamedItem( 'src' )->value;
        if ( ! empty( $src ) ) {
            $scripts_src[] = $src;
        } else {
            $type = $result->item( $key )->attributes->getNamedItem( 'type' )->value;
            if ( empty( $type ) ) {
                $type = 'text/javascript';
            }

            $scripts[$type][] = $el->nodeValue;
        }
    }

    //used by inline code and rich snippets type like application/ld+json
    foreach ( $scripts as $key => $value ) {
        $out .= '<script type="'.$key.'">';

        foreach ( $value as $keyC => $valueC ) {
            $out .= "\n".$valueC;
        }

        $out .= '</script>';
    }

    //external script
    foreach ( $scripts_src as $value ) {
        $out .= '<script src="'.$value.'"></script>';
    }

    return $out;
}

Once done, edit your header.php file. Replace the wp_head() tag by this:

<?php
ob_start();
wp_head();
$themeHead = ob_get_contents();
ob_end_clean();
define( 'HEAD_CONTENT', $themeHead );

$allowedTags = '<style><link><meta><title>';
print theme_strip_tags_content( HEAD_CONTENT, $allowedTags );
?>

And finally, place the code below into your footer.php file, just before the closing </body> tag.

<?php theme_insert_js( HEAD_CONTENT ); ?>

     return $html;
