Adding Ads After First And Second Paragraph of Wor

问题:

I'm hoping someone can help with this question. I have the following working code below in my functions.php file to put Adsense ads after the first paragraph of each post. I'm hoping someone knows how to tweak this code to enable me to also add another ad after the second paragraph. So, in a nutshell, I want ads after the first and second paragraph.

Thanks.....code below.

//Insert ads after first paragraph of single post content.
add_filter( 'the_content', 'prefix_insert_post_ads' );
function prefix_insert_post_ads( $content ) {

    $ad_code = '<div>Ads code goes here</div>';

        if ( is_single() && ! is_admin() ) {
            return prefix_insert_after_paragraph( $ad_code, 1, $content );
    }

    return $content;
}

// Parent Function that makes the magic happen
function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
    $closing_p = '</p>';
    $paragraphs = explode( $closing_p, $content );
    foreach ($paragraphs as $index => $paragraph) {

        if ( trim( $paragraph ) ) {
        $paragraphs[$index] .= $closing_p;
    }

    if ( $paragraph_id == $index + 1 ) {
        $paragraphs[$index] .= $insertion;
    }
}

 return implode( '', $paragraphs );
}

Below is the entire code:

function prefix_insert_after_paragraph2( $ads, $content ) {
    if ( ! is_array( $ads ) ) {
        return $content;
    }

    $closing_p = '</p>';
    $paragraphs = explode( $closing_p, $content );

    foreach ($paragraphs as $index => $paragraph) {
        if ( trim( $paragraph ) ) {
            $paragraphs[$index] .= $closing_p;
        }

        $n = $index + 1;
        if ( isset( $ads[ $n ] ) ) {
            $paragraphs[$index] .= $ads[ $n ];
        }
    }

    return implode( '', $paragraphs );
}

add_filter( 'the_content', 'prefix_insert_post_ads' );
function prefix_insert_post_ads( $content ) {
    if ( is_single() && ! is_admin() ) {
        $content = prefix_insert_after_paragraph2( array(
            // The format is: '{PARAGRAPH_NUMBER}' => 'AD_CODE',
            '1' => '<div>Ad code after FIRST paragraph goes here</div>',
            '2' => '<div>Ad code after SECOND paragraph goes here</div>',
        ), $content );
    }

    return $content;
}
