Create a content node from another content

Question

I'm wondering how to create a content from another content. I'll give an example, it will be easier to understand :

We have a content-type "Planning" which has three fields : 2 user references and one date, which can be multiple filled (let's say the dates are appointments). So in result, a planning will link 2 users and this node will display all the dates these 2 are supposed to meet.

Also, we have another content-type "Appointment".

I'd like that after the creation of the Planning, the appointments get automatically created, always linking the 2users.

First, I've looked into the module Flexi-Field but it doesn't create the node. Then I thought about Rules but I don't know how to create the multiple nodes Appointments due to the multiple date fields.

I know I could do it with Rules through a PHP custom code, but if there's any easier solution, I'd like to hear about them :-)

Thanks for any suggestion !

Cheers all !

Answer 1

If both your content types are defined for Plannning and Appointment already, you can easily create appoint nodes on-the-fly when a Planning node is saved.

You want to look at the following 2 references:

• hook_node_insert()
• Programmatically create nodes

It would look something like this (NOT TESTED):

function mymodule_node_insert($node) {
  if ($node->type == 'planning') {
    foreach (element_children($node->field_appointment_dates) as $a_single_appointment_date) {
      $appt_node = new stdClass();
      $appt_node->type = 'appointment';
      node_object_prepare($appt_node);
      $appt_node->language = LANGUAGE_NONE; // Or your language type ...
      $appt_node->title = 'Some new appointment';
      $appt_node->field_appointment_date = $a_single_appointment_date[0]['value'];
      node_save($appt_node);
    }
  }
}

Answer 2

function planning_nodeapi(&$node, $op) {
    if ($node->type == 'planning' && $op=='insert') {
    $txt = $node->field_plan_texte[0]['value']; // some text
    $user = $node->field_plan_user[0]['uid']; //user reference
    $date = $node->field_plan_dates[0]['value']; // date of appointments, even if multiples
    for ($i=0;$i<count($node->field_dates);$i++){
       $appt = new StdClass();
       $appt->type = 'appointment';
       $appt->uid = 1;
       $appt->title = "pd";
       $appt->field_appt_txt[0]['value']=$txt;
       $appt->field_appt_user[0]['uid'] = $user;
       $appt->field_appt_date[0]['value'] = $node->field_dates[$i]['value'];
       node_save($appt);
    }   
  }
}

This is valid for D6 ;-) Thanks @ tenken !
