I was wondering if anybody can help to get other parameters to the theme_name_form function ?

Example : I fill the form variable with the item I want. I call the theme_name_form which render the form correctly.

How can I have another variable which come from name_form into my theme_name_form() ??

This is what I tried :
in the .module file (hook_theme) :

    'macommande_formulaire' => array(
	'arguments' => array('commandes' => array(), 'total_commandes' => null ),
	'file' => 'macommande.page.php')

and in macommande.Page.php

function theme_macommande_formulaire($form) {
	if ($total_commandes) output.= "Yess :-) ";

And I can't access to the value of $total_commandes... :-(

I assume the second function doesn't know at all about my variable $total_commandes... but how can I pass this value (without a static variable of course ;-) )

Thanks !

I think the arguments that you set in hook_theme are passed to the theme function.
Your function should thus be:

//both the arguments should be in the function statement
function theme_macommande_formulaire($commandes, $total_commandes = null) {
  if ($total_commandes) output.= "Yess :-) ";
}

Correct me if I'm wrong!

Good luck,
Thijs

Thanks for your response !
If I add the parameters in the description of the function like this :

function theme_macommande_formulaire($form, $commandes=>array(), $total_commande=>null, $commandes_existent=>null, $aconfirmer=>TRUE, $total_livraison=>null, $livraison=>array() ) { ... }

I get this error : Parse error: syntax error, unexpected T_DOUBLE_ARROW, expecting ')' in /media/Donnees/www/Sandwichs/sites/all/modules/sandwichs/macommande.page.php on line

It seems that Drupa doesn'ot want me to use "=>" in the declaration ???

If I remove the initialisation of the parameter in the function :

function theme_macommande_formulaire($form, $commandes, $total_commande, $commandes_existent, $aconfirmer, $total_livraison, $livraison ) { ... }

Then, I get this error :

* warning: Missing argument 2 for theme_macommande_formulaire() in /media/Donnees/www/Sandwichs/sites/all/modules/sandwichs/macommande.page.php on line 235.
* warning: Missing argument 3 for theme_macommande_formulaire() in /media/Donnees/www/Sandwichs/sites/all/modules/sandwichs/macommande.page.php on line 235.

* warning: Missing argument 7 for theme_macommande_formulaire() in /media/Donnees/www/Sandwichs/sites/all/modules/sandwichs/macommande.page.php on line 235.

no more on a white screen, but in the messages from drupal (drupal_set_message). It seems that these variables are not initialize but how can I solve this ?? ;-)

Thanks for helping !

When theming forms, you can only pass the $form variable to the theme function. Any extra data needs to be added to the form element, and can then be accessed in the theme function.

$form['id'] = array
(
  '#type' => 'value',
  '#value' => $id;
);
$form['name'] = array
(
  '#type' => 'textfield',
  '#title' => t('Name'),
);
$form['#theme'] = 'myform';

function theme_myform($form)
{
  $id = $form['id']['#value'];
}

OK, thank you for your precise answer. I tought it was like this but because I come from a template with a lot of array of variables, I was wondering if it was possible.

Do you know if I can add an array to your #value of 'id' or of I can only add a string ?

Thanks,

Stéphane

Honestly, testing it on your own would be faster than waiting for me to reply.

But the answer is yes, you can pass an array.
