How to use tinyMCE for user “biographical info” without messing with any core file?

Question

I noticed when you typein the user's “biographical info” on the profile, it shows up in one page! Looks really terrible. So:

Is there a way to use tinyMCE or other solution for user “biographical info” without messing with any core file, and without any plugin?

Thanks a lot.

Answer 1

I’ve written a plugin that replaces the Biographical Info profile field with the WordPress visual editor, TinyMCE, allowing you to editor an author’s biography using rich text using a new function, wp_editor(), that was released with WordPress 3.3.

http://wordpress.org/extend/plugins/visual-biography-editor/

Using this plugin will ensure that the editor isn’t wiped out with the next core update, which you should definitely do for security reasons.

Add this to your functions.php:

/*******************************************
* TinyMCE EDITOR "Biographical Info" USER PROFILE
*******************************************/
function biographical_info_tinymce() {
if ( basename($_SERVER['PHP_SELF']) == 'profile.php' || basename($_SERVER['PHP_SELF']) == 'user-edit.php' && function_exists('wp_tiny_mce') ) {
wp_admin_css(); 
wp_enqueue_script('utils');
wp_enqueue_script('editor');
do_action('admin_print_scripts');
do_action("admin_print_styles-post-php");
do_action('admin_print_styles');
remove_all_filters('mce_external_plugins');

add_filter( 'teeny_mce_before_init', create_function( '$a', '
$a["theme"] = "advanced";
$a["skin"] = "wp_theme";
$a["height"] = "300";
$a["width"] = "440";
$a["onpageload"] = "";
$a["mode"] = "exact";
$a["elements"] = "description";
$a["theme_advanced_buttons1"] = "formatselect, forecolor, bold, italic, pastetext, pasteword, bullist, numlist, link, unlink, outdent, indent, charmap, removeformat, spellchecker, fullscreen, wp_adv";
$a["theme_advanced_buttons2"] = "underline, justifyleft, justifycenter, justifyright, justifyfull, forecolor, pastetext, undo, redo, charmap, wp_help";
$a["theme_advanced_blockformats"] = "p,h2,h3,h4,h5,h6";
$a["theme_advanced_disable"] = "strikethrough";
return $a;' ) );

wp_tiny_mce( true );
}
}
add_action('admin_head', 'biographical_info_tinymce');

. Someone is due for credit on this but i can't remmeber where i have found this..
Anyhow this works great for me

Just adding this to the theme's functions.php solve the problem (prevent stripping of the html from the author's bio):

remove_filter('pre_user_description', 'wp_filter_kses');  
add_filter( 'pre_user_description', 'wp_filter_post_kses' );
