Create plugin with hook

    I strive with the Simple Tagging plugin, and tries to experiment with making things appear in my post form. So – I created this tiny plugin, which only function is to write something to my post-form page, but nothing happens.

    My code:

    <?php
/*
Plugin Name: my plugin test
Plugin URI:
Description: blablabla
Version: 1.3
Author: Siv
Author URI:
*/

add_filter('simple_edit_form', 'srh_print_dill');
function srh_print_dill(){
	print "this should be displayed below my post form";
}

?>

    I found a do_action(‘simple_edit_form’,”) in my edit_post.php file (in admin folder), but I really don’t understand what this means. When I read the codex all the examples are generic, and I’m not able to find an explanation of simple_edit_form nor do_action().

    If anyone has a good idea I’ll be overlykkelig! (norwegian for very, very, very, ….., very happy)

    Thanks, but that made no different. But I refactorated the plugin and now I’m able to print the word “ushj” where the form should be, but the form it self does not appear.
    I can print out strings right ’till the form starts, but then it stops.

     print "tralalala";
print '<div id="lptagstuff" class="sta-group">            <fieldset class="sta-box" id="posttags">
<h3 class="sta-handle">'
. __('Tags (comma separated list)') . '</h3>
<div class="sta-content">
<input class="wickEnabled" name="tag_list" id="stp_tag_entry" value="' . $post_tags . '" />
					<input type="hidden" name="simpletaggingverifykey" id="simpletaggingverifykey" value="' . wp_create_nonce('simpletagging') . '" />' . '
					<script type="text/javascript" language="JavaScript">'
. $ta_result . '</script>
					<script type="text/javascript" language="JavaScript" src="' . $this->sTagObj->info['install_url'] . '/simpletagging.type-ahead.js"></script>
<div id="stp_taglist">
<h4>' . (($opt['dsp_suggested']) ? 'Suggested Tags' :
'Tags') . ':</h4>
<p>' . $result_tags_str . '</p>
<div id="clearer">&nbsp;</div>
</div>
</div>
</fieldset>
</div>';

    The “tralala” gets printed, the following not. What is this????

    Maybe you shouldn’t use multiple print statements and do something like:

    PHP heredoc notation:

    add_filter('simple_edit_form', 'srh_print_dill');

function srh_print_dill()
{
   echo <<<EOHTML

      this should be displayed below my post form

      some more text on another line

EOHTML;
}

    OR 

    add_filter('simple_edit_form', 'srh_print_dill');

function srh_print_dill()
{
   ?>
      this should be displayed below my post form

      some more text on another line
   <?php
}

    Another thing to watch for that is mentioned in this forum post:

    http://wordpress.org/support/topic/51631

    is that if you want your added XHTML to show up when you have gone to Manage > Posts or Manage > Pages, you need to use the edit_form_advanced hook as well.
