Fiche Produit - Ajout Photo Produit

Re-bonjour,

Sur la modification du pdf_standard.module.php (génération de la fiche produit) j’essaie de rajouter la photo du produit.
Je bloque cependant sur la fonction « liste_photo » de product.class.pdf qui me retourne une erreur :

Le code est très court :

$id_product_photo=$object->rowid;
	$arephoto = false;
	if (! $arephoto)
	{
	$dir = DOL_DATA_ROOT.'/'.$objet->ref;
	      foreach ($id_product_photo->liste_photos($dir,1) as $key => $obj)
	      {
	      $filename=$obj['photo'];
	      $realpath = $dir.$filename;
	      $arephoto = true;
	      }
	}
						
	if ($realpath && $arephoto) $pathphoto=$realpath;

		// Define size of image if we need it
		$imglinesize=array();
		if (! empty($pathphoto)) $imglinesize=pdf_getSizeForImage($pathphoto);

		$posYAfterImage=42;

		// We start with Photo of product
					
		if (isset($imglinesize['width']) && isset($imglinesize['height']))
		{
		$pdf->Image($pathphoto, $tab_top, $tab_top, $imglinesize['width'], $imglinesize['height'], '', '', '', 2, 300);	// Use 300 dpi

Bonjour :happy:
$object->liste_photos(…) non ?

Pareil,

Le problème je pense c’est que je n’ai rien qui ressort de la variable $id_product_photo qui fait appel au rowid du produit

liste_photos() est une fonction de classe de product
donc de $object et non pas de rowid de l’objet je pense.

D’accord… Même si je n’ai pas tout saisi…

Mais pourtant il est bien appelé comme ca dans la génération PDF ‹ Azur › des propal

$objphoto = new Product($this->db);
$objphoto->fetch($object->lines[$i]->fk_product);
$dir = $conf->product->dir_output.'/'.$midir;
foreach ($objphoto->liste_photos($dir,1) as $key => $obj)

Du coup en utilisant ce code tu as encore une erreur?
moi j’aurai mis un truc genre

...
$objphoto = new Product($this->db);
$objphoto->fetch($object->id);
// ou $objphoto->fetch('', $object->ref);
$dir = $conf->product->dir_output.'/'.$midir;
foreach ($objphoto->liste_photos($dir,1) as $key => $obj)
....

Merci pour tes solutions.
En modifiant un peu le code, plus d’erreur mais l’image ne s’affiche toujours pas…

J’ai encore réduit le code :

//Photo
$objphoto = new Product($this->db);
$objphoto->fetch('', $object->ref);

$dir = $conf->produit->dir_output ."/" .dol_sanitizeFileName($objphoto);
foreach ($objphoto->liste_photos($dir,1) as $key => $obj)
{
	$filename=$obj['photo'];
	$realpath = $dir.$filename;
}

// Define size of image
$imglinesize=array();
if (! empty($realpath)) $imglinesize=pdf_getSizeForImage($realpath);

// We start with Photo of product
if (isset($imglinesize['width']) && isset($imglinesize['height']))
{
	$pdf->Image($realpath, $tab_top, $tab_top, $imglinesize['width'], $imglinesize['height'], '', '', '', 2, 300);
	$posYAfterImage=$tab_top+$imglinesize['height'];
}

Cela fonctionne avec ce code :

//Contenu
					//Photo
					$objphoto = new Product($this->db);
					$objphoto->fetch($object->ref);
					
					$dir = $conf->produit->dir_output ."/" .dol_sanitizeFileName($object->ref)."/";
					foreach ($objphoto->liste_photos($dir,1) as $key => $obj)
						{
						$filename=$obj['photo'];
						$realpath = $dir.$filename;
						}

					// Define size of image if we need it
					$imglinesize=array();
					if (! empty($realpath)) $imglinesize=pdf_getSizeForImage($realpath);

					$tab_top=42;

					// We start with Photo of product
					
					if (isset($imglinesize['width']) && isset($imglinesize['height']))
					{
						$pdf->Image($realpath, 45, 50, $imglinesize['width'], $imglinesize['height'], '', '', '', 2, 800);	// Use 300 dpi
						// $pdf->Image does not increase value return by getY, so we save it manually
						$tab_top=47+$imglinesize['height'];
					}

Bonjour,

Pour InfraSPackPlus qui gère très bien les photos je commence par

include_once DOL_DOCUMENT_ROOT .'/core/lib/files.lib.php'; include_once DOL_DOCUMENT_ROOT .'/core/lib/images.lib.php';

Ensuite attention à l’option cachée !

PRODUCT_USE_OLD_PATH_FOR_PHOTO

Cordialement,
Sylvain Legrand.

Pourquoi, y’a une fonction appelée sur ces fichiers ?

Oui pour PRODUCT_USE_OLD_PATH_FOR_PHOTO
J’ai fait exprès de le retirer parce que cela n’a plus lieu d’être… < v4

Bonjour :happy:
@leboubou111
Peux-tu éditer le sujet de ton topic en y ajoutant au début [RESOLU] stp ?

Oui, mais je compte partager mon fichier modifié… Ca va surement servir à d’autre.
Il serai bien de l’intégrer dans la prochaine version de Dolibarr.

J’ai fait déjà quelques améliorations.

Il me reste à mettre les unités sur le poids, les dimensions, la surface et le volume.
Aussi j’aimerai ajouter une nouvelle page si la description est longue.

1 J'aime

Pour terminer mon fichier j’ai besoin d’un dernier coup de main.

Comment faire pour faire passer sur une nouvelle page si la hauteur du bloc dépasse de la page ?

Exemple avec ce code :

// Affiche le libellé
if ($object->label)
{
	$currentY = $pdf->GetY();
	$nexY+=2; // espace de 2mm
	$pdf->writeHTMLCell(...)
	$nexY = $pdf->GetY();
	$nexY+=5; // espace de 5mm
	$currentnewY = $pdf->GetY();
	$height_label=$currentnewY-$currentY;
}
else
{
	$height_label=0;
}

$pdf->AddPage();

Bon j’ai fini mon code…
Juste la fonction AddPage qui ne fonctionne pas… Je pense qu’il n’arrive pas à calculer

if ($nexY+$heightforfooter+$this->height_URL > $this->page_hauteur)

tout simplement parce que la fonction où est la variable $this->height_URL n’a toujours pas été appelée.

Mais pour savoir si l’encadré suivant tiendra sur la page j’ai besoin de connaitre sa hauteur en avance.

Je joins tous le code qui fait 750 lignes.
C’est la première fois que je code. Soyez indulgent svp.

Pour que le code fonctionne il faut rajouter deux options

MAIN_GENERATE_FICHE_PRODUCT_WITH_PICTURE -> 1 = Génération Fiche Produit - Ajoute l’image du produit
MAIN_GENERATE_FICHE_PRODUCT_MAX_SIZE_PICTURE -> Valeur = Génération Fiche Produit - Taille limite de l’image du produit en mm (110 par défaut)

Je pense avoir trouvé en utilisant la fonction pdfGetHeightForHtmlContent et/ou getStringHeight
Ca va être long à intégrer…

Code terminé :

Voici la nouvelle page Fiche Produit

Modifications apportées :

[ul]
[li]Plusieurs améliorations esthétiques[/li]
[li] Ajout cadre « Description’, 'Informations Supplémentaires » et « Notes »[/li]
[li] Encadrement des informations supplémentaires (poids, taille, etc…)[/li]
[li] Modification taille carractère[/li]
[li]Ajout de la première photo (identique au modèle « Azur ») au début de la fiche (et centré)[/li]
[li] Si renseigné MAIN_GENERATE_FICHE_PRODUCT_WITH_PICTURE dans Configuration->Divers[/li]
[li] On peut définir la hauteur maximum de l’image MAIN_GENERATE_FICHE_PRODUCT_MAX_HEIGHT_SIZE_PICTURE en mm (par défaut : 110mm)[/li]
[li] La largeur s’effectue automatiquement[/li]
[li]Ajout du lien URL si renseigné[/li]
[li]Ajout des unités (Kg, cm, m², etc…)[/li]
[li]Ajout des notes publiques (quand sera dispo sur prochaine version)[/li]
[li]Les informations ne s’affichent que si renseignées sur la fiche produit[/li]
[li]Saut de page automatique en fonction de la hauteur de l’élément à afficher[/li]

J’en ai profité pour supprimer tout le code qui ne servait à rien.

Fonctionne sur la version Dolibarr 9.0.1.
Pas testé sur les versions antérieurs mais devrait fonctionner.

Bonjour :happy:
Si tu veux que ton code soit intégré, amélioré etc propose le sur github :

1 J'aime

J’approuve le passage de la PR sur le github… Surtout que c’est utile et on pourra t’aider à corriger tout ce qui est poids et mesures qui va changer dans la v10 à ec un nouveau code et gestion unite/ conversion

C’est fait : https://github.com/Dolibarr/dolibarr/issues/11039

Par contre je n’ai pas réussi à faire de PR, du coup j’ai fait une Issue.

J’ai corrigé le code pour qu’il soit multilingue avant de poster.
