post editor changes & to &

1 Views

The editor seems to change every ampersand (&) to &

is there any way to get rid of that function or something? I really need the only & to make my variables work.

  1. I dont know what you are doing with your shortcode but it is good practice to serialize and parse data so that it displays beautifully.

    Since you need to look for & and not for & just use $data = str_replace("&", "&", $data). Also you could look in the php manual for urldecode() and urlencode().

    Read the note there:

    Be careful about variables that may match HTML entities. Things like &amp, &copy and &pound are parsed by the browser and the actual entity is used instead of the desired variable name. This is an obvious hassle that the W3C has been telling people about for years. The reference is here: » http://www.w3.org/TR/html4/appendix/notes.html#h-B.2.2.
    PHP supports changing the argument separator to the W3C-suggested semi-colon through the arg_separator .ini directive. Unfortunately most user agents do not send form data in this semi-colon separated format. A more portable way around this is to use & instead of & as the separator. You don’t need to change PHP’s arg_separator for this. Leave it as &, but simply encode your URLs using htmlentities() or htmlspecialchars().

    I hope this sheds some light onto your question.

  2. WordPress’ default editor is escaping by default all html entities such as <, >, & and etc. You can check the Codex for more information. If you want your special characters to be printed as is, you can use the PHP function html_entity_decode() to decode the encoded entities:

    function wpse_56268_decode_html_entities($content) {
    return html_entity_decode($content);
}

add_filter( 'the_content', 'wpse_56268_decode_html_entities' );

    When a post is fetched it will decode the encoded characters and will print them in their original value. Although I don’t recommend it.

    This:

    &lt;strong&gt;Below we have a list&lt;/strong&gt;
&lt;ul&gt;
    &lt;li&gt;List item 1&lt;/li&gt;
    &lt;li&gt;List item 2&lt;/li&gt;
&lt;/ul&gt;

    Will be converted to this:

    <strong>Below we have a list</strong>
<ul>
    <li>List item 1</li>
    <li>List item 2</li>
</ul>

  3. This might be an obvious answer, but have you actually tried to save the post and view it and see if the shortcode works?

    As far as I understand it, & is the correct way for & to display, no matter what its doing, otherwise the code would be invalid. The shortcode plugin should be coded to anticipate this, and work just fine.

    What is the exact name of the shortcode plugin you are using?
