   I have a weird problem with a custom plugin.

   This is the code to show inside a page:

   // replace tag in content with myplugin
   function myplugin_init($content){
   	if( strpos($content, '<!--myplugin-->') !== false ){
   		$code = myplugin_function();
   		$content = str_replace( '<!--myplugin-->', $code, $content );
   	}
   	return $content;
   }

   and then:

   add_filter('the_content','myplugin_init');

   Looks ok, but the plugin always show first in the page, no matter where I put it.

   In my page have some text, and then: <!--myplugin-->. But the plugin goes first. The weird thing is the html code show the plugin code first, so it's not only a css float, position problem.

   I thinks the problem is the way the plugin replace the content. ¿Any ideas?

   PS: Sorry about my english, not my native language.

   Can't you just "echo" it exactly where you want it to come up?

   Hi,
   No, because It's a regular page. The content is filled by the Write tab, in the administration panel of WordPress.

   Ok, Update: If I change the $code to this:

   // replace tag in content with myplugin
   function myplugin_init($content){
   	if( strpos($content, '<!--myplugin-->') !== false ){
   		$code = "Hello world!";
   		$content = str_replace( '<!--myplugin-->', $code, $content );
   	}
   	return $content;
   }

   It's show correctly. When it's a function, goes first. In the content of the page (by the write tab in de administratios panel of wordpress) I have:

   some text..... bla bla...

   <!--myplugin-->

   more text.... bla bla...

   And the result is a page like that:

   PLUGIN CONTENT

   some text..... bla bla...
   more text.... bla bla...

   Ok. I figured out.

   The second function called by the myplugin_init function (In this case "myplugin_function" or, in others words, the plugin itself), can't contain an "echo", it must be changed by this:

   $somevar = "Hello world!";
   return $somevar;

   ...and that's all. All works fine now.
