Question

Okay let me see if I can explain this right. In wordpress we have a box to insert an excerpt. We need to add a second excerpt box. Instead of manually adding a custom field to every post I have placed a function to automatically add a custom field in the form of a Meta box on the admin post page.

Okay so this is the problem that i’m having this function is working except for the fact that whatever you enter into this field it loses it’s line breaks. So when our writers are contrubuting to this field in order to keep formatting of the block of text I have to manually add
to the end of the paragraph.

Here is my code:

function my_create_post_meta_box() {
    add_meta_box( 'my-meta-box', 'Second Excerpt', 'my_post_meta_box', 'post', 'normal', 'high' );
}

function my_post_meta_box( $object, $box ) { ?>
<p>
    <label for="second-excerpt">
        <strong>Second Excerpt With Images for Post List Page</strong>
    </label>
    <textarea name="second-excerpt" id="second-excerpt" cols="60" rows="4" tabindex="30" style="width: 97%;" wrap="hard"><?php echo wp_specialchars( get_post_meta( $object->ID, 'Second Excerpt', true ), 1 ); ?></textarea>
    <input type="hidden" name="my_meta_box_nonce" value="<?php echo wp_create_nonce( plugin_basename( __FILE__ ) ); ?>" />
</p>
<?php
}

function my_save_post_meta_box( $post_id, $post ) {

    if ( !wp_verify_nonce( $_POST['my_meta_box_nonce'], plugin_basename( __FILE__ ) ) )
        return $post_id;

    if ( !current_user_can( 'edit_post', $post_id ) )
        return $post_id;

    $meta_value = get_post_meta( $post_id, 'Second Excerpt', true );
    $new_meta_value = stripslashes( $_POST['second-excerpt'] );

    if ( $new_meta_value && '' == $meta_value )
        add_post_meta( $post_id, 'Second Excerpt', $new_meta_value, true );

    elseif ( $new_meta_value != $meta_value )
        update_post_meta( $post_id, 'Second Excerpt', $new_meta_value );

    elseif ( '' == $new_meta_value && $meta_value )
        delete_post_meta( $post_id, 'Second Excerpt', $meta_value );
}

Thanks and any help would do.

Okay I have found another solution to my problem. Thank you Tatu for getting my brain workin. For those who are looking for a solution this is what I did:

$new_meta_value = "<p>" . implode( "</p>\n\n<p>", preg_split( '/\n(?:\s*\n)+/', $new_meta_value ) ) . "</p>";
