When inserting images into posts auto add a wrapping div

2 Views

When I add images to a post via the TinyMCE editor I’d like WP to add a wrapping div around the <img> tag like <div class="img-wrapper"><img src="url-to-image" alt="image" /></div>. Is that somehow possible?

  1. I think it is a better idea, if you filter the output, the the_content and add the div on all images. It is better for feature, if you will remove this markup, it is not inside the database.

    add_filter( 'the_content', 'fb_add_div_to_img' );
function ( $content ) {

    // find img and add markup
    return $content;
}

    To find and replace the img in content use a regex, like this

    If you use the regex preg_match_all( '/<img [^>]*src="([^"]+)"[^>]*>/', $content, $arr, PREG_PATTERN_ORDER); then you get a array. Inside this array you find the img tag with all values, $arr[0]. Enhance this var with your markup and return to the var $content. Also here a example from the web. Additional hint for a regex tester, there I like: Regex Test Tool

    But it is also possible to add markup on insert images in the editor:

    add_filter( 'image_send_to_editor', 'fb_give_linked_images_class', 10, 8 );
function fb_give_linked_images_class( $html, $id, $caption, $title, $align, $url, $size, $alt = '' ){

    $html; //contains the string you need to edit, you might want to consider to rebuild the complete string.

    return $html;
}
