custom inputfieldselect

[Frank Vèssia]

I created (or trying to) an inpufieldselect that shows me all files stored in a server folder and save the value as text.

It works good but i have two problems.

First: I need to execute a function called "sendVideo" after the page is saved based on my select value. I tried to add an hookafter save but the code is executed everytime a page is saved and not only the current page.

public function init() {
$this->pages->addHookAfter('save', $this, 'sendVideo'); 
}

Second: I need to execute my code only if i change the value of my select and do nothing if not .

This is my entire code

<?php

class FieldtypeSelect extends Fieldtype {

    public static $defaultOptionValues = array ();

    public static function getModuleInfo() {
  return array(
  'title' => 'Select temporary videos',
  'version' => 100,
  'summary' => 'This Fieldtype get files stored in /toencode/ folder',
  'singular' => true, 
  'autoload' => true, 
  );
    }

   public function init() {
	$this->pages->addHookAfter('save', $this, 'sendVideo'); 
   }

   public function sendVideo($event) {
	$page = $event->arguments[0]; 
	$vfile = "http://".$_SERVER['HTTP_HOST']."/videodaconvertire/".$page->videotoconvert;

	$filename = $page->id;

This is made for adding a video to a page using encoding.com apis.

Basically i upload some videos in a folder, than i create a page and choose a video for encoding, after the page is saved i use encoding.com apis to send request to their server  via xml and after the video is encoded and thumbnails created with a callback function that call an hidden pw page i editing the page, add the thumbnails and save it again.

If I'm understanding correctly, I don't think that you need that 'save' hook at all. Instead, you can just implement this function which is already part of the Fieldtype interface, and PW will call it only on the $page and $field that you expect:

<?php

public function ___savePageField(Page $page, Field $field) {

    if($page->isChanged($field->name)) {
        // your sendVideo code here - you should probably put it in a new function and call that function here
    }

    // since you aren't handling PW's DB save, let it do the rest: 
    return parent::___savePageField($page, $field); 
}

See this file which provides the full interface and functions that you can override in any Fieldtype:

Thanks, it works like a charm  ;D
