Automatically add text to an article in Joomla! If you want to add standard text ("This text has been added automatically by Joomla!") to the end of each article that is submitted from the front end, follow these steps:

  1. Create a template override for the file <joomla_root>/components/com_content/views/article/tmpl/form.php.
    • Create a folder called <joomla_root>/templates/<your template>/html/com_content/article.
      For the "beez" template, this folder is called <joomla_root>/templates/beez/html/com_content/article.
    • Copy the standard form.php file from the components folder above to the templates folder.
      Note: If you already have a form.php file in this folder, don't copy the file. Just edit it as indicated below.
  2. Edit the copy of the file you made in the override folder as follows. Find the line
       var text = <?php echo $this->editor->getContent( 'text' ); ?>
    This is line 49 in the 1.5.8 version of this file. Change this to the following:
       var text = <?php 
    	$addToText = '<p>Joomla! automatically added this text.</p>'; 
    	if (strpos($this->article->text, $addToText) === false) {
               $this->article->text .= $addToText;
       echo $this->editor->getContent( 'text' ); ?>
    This is checking that the text to be added is not already in the article. If it is not, then it is added to the article.

Don't forget to change the text in the variable $addToText to whatever you need.

That's it. Now, when you edit an article from the front end, this text will automatically be added. Note that this change does not affect editing from the back end. Also, since this is done as a template override, it only affects pages that use the overridden template.
