documentation index

This page give you some advises how to integrate complementary attributes (extrafields) into PDF models of Dolibarr.

This is a exemple and needs to be adapted to your needs. It is based on billing document but it will be the same for the others modules

Prerequisite

You can read the following links before, some paragraph will come from these pages :

• Create a PDF document template
• Extrafields

Create a Complementary Attributes on Invoices Module

First you need to create your complementary attribute. This complementary attributes can be of two types :

• Module complementary attribute
• Line complementary attribute

Access to the configuration

Go on the Dolibarr application > Setup > Modules/Applications

Click on the parameter icon of the Invoices module Then you can create Module or Line complementary attribute

Module complementary attribute

Go on the Complementary attributes (invoices) tab

Put the all the mandatory fields, especially the Attribute code that will be used in the next chapters

You should end up with something like that :

Line complementary attribute

Go on the Complementary attributes (lines) tab

Put the all the mandatory fields, especially the Attribute code that will be used in the next chapters

You should end up with something like that :

Verification on the Invoices Module

Clic on Billing|Payement and select New invoice

If you have created a Module complementary attribute, you should have that :

If you have created a Line complementary attribute, you should have that :

Create a new invoice template

All the steps are describes there Create a PDF document template

• Open the core\modules\facture\doc\ directory
• Copy the pdf_crabe.modules.php
• Rename the copy as pdf_my_template.modules.php
• Edit and make the following changes in the code:

1. Rename class pdf_crabe to class pdf_my_template
2. Rename constant $this->name = "crabe"; to $this->name = "my_template";
3. Update the $this->description with your description
4. Save file. Now the template will be available in the list of models in Dolibarr
   
5. Test this model (by generating a pdf) before going further ...

Modify the new invoice template

• Open the new template pdf_my_template.modules.php
• Look for the last require_one lines ate the beginning of the template
• Add the line

  require_once DOL_DOCUMENT_ROOT.'/core/class/extrafields.class.php';
  

  

Module complementary attribute

• Find the

  function write_file
  

• Just before the

  // Affiche notes
  

• Add the code to load extrafield array in object

  $extrafields = new ExtraFields($db);
  $extralabels=$extrafields->fetch_name_optionals_label($object->table_element);
  

• Add the code to load extrafield into object

  $object->fetch($rowid);
  $object->fetch_optionals($rowid,$extralabels);
  

• Add the code to print the extrafiled

  $pdf->writeHTMLCell (190,3, $this->posxdesc-1, $tab_top-5, $outputlangs->convToOutputCharset($object->array_options['options_my_extra']),0,1);
  

  
• Result :
  

Line complementary attribute

• Find

  $object->fetch_thirdparty();
  

• Add, just after, the code to load extrafield array in object

  $extrafields = new ExtraFields($db);
  $extralabels=$extrafields->fetch_name_optionals_label($object->table_element);
  

  
• Find

  // Loop on each lines
  for ($i = 0; $i < $nblignes; $i++)
  {
  

• Add, just after, the code to load line extrafield into object

  $object->lines[$i]->fetch_optionals($object->lines[$i]->rowid,$extralabelsline);
  

  
• Find

  $posYAfterDescription=$pdf->GetY();
  

• Add, just before, the code to display the line extrafiled

  $pdf->MultiCell(0, 3, $outputlangs->convToOutputCharset($object->lines[$i]->array_options['options_my_line_extra']), 0, 'L', 0);
  

  
• Result :
  

Special Case for Extrafields type Select list

Configuration

You can create a line or a module extrafield with the type Select list

Verification on the Invoices Module

You should have a Module or Line extrafield (on this print screen this a Module)

Invoice Template

On the php invoice template, if you use the classical php code to print the extrafield, you will print the code (1 or 2 in our exemple) instead of printing the label (Hello Word or Hello Alone in our exemple).

To display the label instead of the code, you shoudl replace the :

$outputlangs->convToOutputCharset($object->array_options['options_my_extra'])

by :

$extrafields->showOutputField('my_extra', $object->array_options['options_my_extra'])
