If the code can’t find body, it erases part of the page

  • Here is the body tag from my template:

    <body class="home page-template-default page page-id-9 logged-in admin-bar no-customize-support wp-custom-logo wp-embed-responsive fl-builder no-sidebar nav-float-right separate-containers fluid-header active-footer-widgets-4 header-aligned-left dropdown-hover full-width-content" itemtype="https://schema.org/WebPage" itemscope>

    Here is the plugin code:

    add_action( 'wp_footer', function() use($yydev_tag_body_tag, $yydev_tagmanager_settings) {
    if( yydev_tagmanager_exclude_pages_check($yydev_tagmanager_settings) ) {

        $yydev_buffer  = ob_get_clean();

        $yydev_str_replace ='/<[bB][oO][dD][yY]\s[A-Za-z]{2,5}[A-Za-z0-9 "_=\-\.]+>|<body>/';
        ob_start();

        if( preg_match($yydev_str_replace, $yydev_buffer, $yydev_buffer_return) ) {
            $yydev_new_code = $yydev_buffer_return[0] . $yydev_tag_body_tag;
            $yydev_new_code = preg_replace($yydev_str_replace, $yydev_new_code, $yydev_buffer);
            echo $yydev_new_code;
        } // if( preg_match($yydev_str_replace, $yydev_buffer, $yydev_buffer_return) ) {
    ob_flush();
} // if( yydev_tagmanager_exclude_pages_check($yydev_tagmanager_settings) ) {

    The regexp does not match the tag because it does not contain / and :

    Moreover, if preg_match returns false, the code will lost part of content previously stored in yydev_buffer

    So the correct code should be

    add_action( 'wp_footer', function() use($yydev_tag_body_tag, $yydev_tagmanager_settings) {
    if( yydev_tagmanager_exclude_pages_check($yydev_tagmanager_settings) ) {

        $yydev_buffer  = ob_get_clean();

        $yydev_str_replace ='/<[bB][oO][dD][yY]\s[A-Za-z]{2,5}[A-Za-z0-9 "_=\-\.\/:]+>|<body>/';
        ob_start();

        if( preg_match($yydev_str_replace, $yydev_buffer, $yydev_buffer_return) ) {
            $yydev_new_code = $yydev_buffer_return[0] . $yydev_tag_body_tag;
            $yydev_new_code = preg_replace($yydev_str_replace, $yydev_new_code, $yydev_buffer);
            echo $yydev_new_code;
        } // if( preg_match($yydev_str_replace, $yydev_buffer, $yydev_buffer_return) ) 
{
        else {
            echo $yydev_buffer;
        }
        ob_flush();
} // if( yydev_tagmanager_exclude_pages_check($yydev_tagmanager_settings) ) {

    This seems to explain why when I preview new pages that are still drafts and therefore contain a question mark in the class definition like this : <body class=”some-class another-class ?p=28734″>, the whole body is missing so I have a white screen and no error messages.

    So, please include a question mark in the improved regex above!
