Quick php coding question–how to call a wordpress tag to be used as a variable

  • I am trying to use the following code to strip the html tags out of a post to offer a text-only version of the post by clicking a link.

    Basically, the script is looking for $document, an html document. However, being php-illiterate, I do not have any idea how to call the_content(__(‘(more…)’)); effectively. When I simply insert $document = the_content(__(‘(more…)’)); I get the original non-stripped html. I am trying to use this code in a page that also has code to display the original html (no problem there), so I dont just want to pass the resulting text into its own file.

    <?php
    // $document should contain an HTML document.
    // This will remove HTML tags, javascript sections
    // and white space. It will also convert some
    // common HTML entities to their text equivalent.

    $search = array (‘@<script[^>]*?>.*?</script>@si’, // Strip out javascript
    ‘@<[\/\!]*?[^<>]*?>@si’, // Strip out HTML tags
    ‘@([\r\n])[\s]+@’, // Strip out white space
    ‘@&(quot|#34);@i’, // Replace HTML entities
    ‘@&(amp|#38);@i’,
    ‘@&(lt|#60);@i’,
    ‘@&(gt|#62);@i’,
    ‘@&(nbsp|#160);@i’,
    ‘@&(iexcl|#161);@i’,
    ‘@&(cent|#162);@i’,
    ‘@&(pound|#163);@i’,
    ‘@&(copy|#169);@i’,
    ‘@&#(\d+);@e’); // evaluate as php

    $replace = array (”,
    ”,
    ‘\1’,
    ‘”‘,
    ‘&’,
    ‘<‘,
    ‘>’,
    ‘ ‘,
    chr(161),
    chr(162),
    chr(163),
    chr(169),
    ‘chr(\1)’);

    $text = preg_replace($search, $replace, $document);

    ?>

  • the_content_rss();

    get_the_content();

    Ah, should have read the whole post. Mine echoes out the content stripped of html. get_the_content(); doesn’t echo, strip_tags(get_the_content()) will strip html from the content.

    >>> strip_tags(get_the_content()) will strip html from the content.

    Will it also strip scripts and convert html entities into the corresponding ASCII characters?

    Thanks.

    OK, so the javascript is still not being stripped, just the <script> tag, even though that code says it removes javascript.

    The script that won’t strip is the “sticky post” script:

    <script type=”text/javascript”>window.document.getElementById(‘post-7’).parentNode.className += ‘ adhesive_post’;</script>

    It comes out like this:

    window.document.getElementById(‘post-7’).parentNode.className += ‘ adhesive_post’; [1]

    Another thought: will this lingering script invalidate my RSS feeds?
