Editing a node content

Create site25 by copying site24.

  1. /cms
    1. ...
    2. site24
    3. site25

In this chapter, we are going to create the node content editor.

To test the result online, enter http://www.frasq.org/cms/site25 in the address bar of your navigator. Identify yourself with the name foobar and the password f00bar. Edit the page Legal information. The editor displays the different contents of the node in a series of input fields. Notice that content 2 is evaluated by PHP.

Leave the content type selector on Text and press Add. Cut and paste the text <p><b>frasq.org</b></p> from content 2 to the new content. Change the display order by entering 3 in the field next to the position of content 2 and 2 in the field next to the position of content 3. Press Modify at the end of the page. Delete content 2.

NOTE: In this demonstration version, the content of the site can not be modified.

Edit the file blocks/nodeeditor.php and modify the end of the function nodeeditor to add the content returned by the function nodecontenteditor to the view:

  1.     $content_editor = build('nodecontenteditor', $lang, $clang, $node_id);
  2.  
  3.     $errors = compact('missing_node_name', 'bad_node_name', 'missing_node_title');
  4.  
  5.     $output = view('editing/nodeeditor', $lang, compact('clang', 'node_name', 'node_title', 'node_abstract', 'node_cloud', 'content_editor', 'errors'));

Insert this content at the end of the files views/en/editing/nodeeditor.phtml for the version in English and views/fr/editing/nodeeditor.phml for the version in French:

  1. <h4>Contents</h4>
  2. <?php echo $content_editor; ?>
  1. <h4>Contenu</h4>
  2. <?php echo $content_editor; ?>

Add the file nodecontenteditor.php in the folder blocks with the following content:

  1. /cms/site25
    1. blocks
      1. nodecontenteditor.php
  1. require_once 'readarg.php';

Edit the file models/node.inc and add the functions node_set_contents, node_create_content and node_delete_content:

  1. function node_set_contents($lang, $node_id, $node_contents) {
