En compl\u00e9ments des informations d\u00e9j\u00e0 disponible sur la documentation d\u00e9veloppeur de prestashop sur la gestion globale des images : https:\/\/devdocs.prestashop.com\/1.7\/webservice\/tutorials\/advanced-use\/image-management\/
Cet article d\u00e9taille bri\u00e8vement la gestion des images des produits via l’api sous Prestashop.

Les tests ont \u00e9t\u00e9 fait sur une version 1.7.6.x de prestashop mais l’api ayant assez peu boug\u00e9 cela doit \u00eatre fonctionnel sans doute sur les versions 1.6 \u00e9galement.

Le point essentiel \u00e0 retenir dans les api \u00e9tant qu’une url peut avoir un comportement diff\u00e9rent en fonction de la m\u00e9thode par laquelle elle est appell\u00e9e ( GET \/ POST \/ PUT )

Je pars du principe que les acc\u00e8s n\u00e9cessaire \u00e0 l’api sont d\u00e9j\u00e0 d\u00e9finis, et la gestion de l’api est effectu\u00e9e via la librairie propos\u00e9e par Prestashop en php ( cf. https:\/\/devdocs.prestashop.com\/1.7\/webservice\/tutorials\/prestashop-webservice-lib\/ )

Pour mon exemple d’illustration je me sers d’une version d\u00e9mo de prestahop avec les produits de base.
Dont l’url sera http:\/\/www.prestashop.local\/tests\/1769\/
Et on va jouer avec l\u2019identifiant produit 19<\/strong> , le \u00ab\u00a0mug personnalisable\u00a0\u00bb

Les appels webservice qui seront ex\u00e9cut\u00e9 via la lib Prestashop seront wrapp\u00e9s dans le code suivant
Et je rajoute \u00e9galement une fonction qui va permettre de simplifier les appels \u00e0 la librairie curl .<\/p>\n\n\n\n

\n\n\n\n\n
Visualiser la liste images d'un produits<\/h3>\n\n\n\n
Il est possible de visualiser directement les informations en acc\u00e9dant \u00e0 l'url http:\/\/www.prestashop.local\/tests\/1769\/api\/images\/products\/19 <\/strong>( m\u00e9thode GET )
ou via un appel du webservice :<\/p>\n\n\n\n
$webService = new PrestaShopWebservice($url, $key, false);\n    $opt = array('resource' => 'images\/products'); \/\/Url d'appel\n    $opt['id'] = '19'; \/\/Identifiant du produit\n    $xml = $webService->get($opt);\n    echo $xml->asXML();\n<\/pre>\n\n\n\n
On obtiens la r\u00e9ponse suivante :<\/p>\n\n\n\n
\n\n\n\n\n<\/image>\n<\/prestashop>\n<\/pre>\n\n\n\n
Ce qui nous permets de savoir que l'identifiant de l'image de ce produit est le 22<\/strong><\/p>\n\n\n\n
Visualiser une image produit<\/h3>\n\n\n\n
A partir de l'identifiant r\u00e9cup\u00e9r\u00e9 plus haut il est maintenant possible visualiser l'image du produit directement dans le navigateur en chargeant l'url :
http:\/\/www.prestashop.local\/tests\/1769\/api\/images\/products\/19\/22<\/p>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
Ou alors de l'enregistrer dans un fichier via un appel du code suivant ( pas besoin d'appel api )<\/p>\n\n\n\n
file_put_contents(\n        'img-produit-19-22.jpg',\n        file_get_contents('http:\/\/apiKey@www.prestashop.local\/tests\/1769\/api\/images\/products\/19\/22')\n    );\n<\/pre>\n\n\n\n
Ajouter une image \u00e0 un produit<\/h3>\n\n\n\n
L'appel doit se faire via un appel curl ou via un formulaire html sur l'url en POST<\/strong> sur l'url http:\/\/www.prestashop.local\/tests\/1769\/api\/images\/products\/19<\/strong> 
( qui est la m\u00eame que pour avoir la liste des image du produit )<\/p>\n\n\n\n
\/**\n * Ajout d'une image\n *\/\n$ch = initCurl('images\/products\/19');\ncurl_setopt($ch, CURLOPT_POST, true);\ncurl_setopt(\n    $ch,\n    CURLOPT_POSTFIELDS,\n    array(\n        'image' => new CurlFile(\n            '\/chemin\/absolu\/ver\/image.png'\n        )\n    )\n);\n<\/pre>\n\n\n\n
Dans la r\u00e9ponse api on re\u00e7oit les informations de la nouvelle image envoy\u00e9e ( son identifiant notamment), qui est 24<\/strong><\/p>\n\n\n\n
\n\n\n\n<\/id>\n<\/id_product>\n<\/position>\n<\/cover>\n<\/language><\/language><\/legend>\n<\/image>\n<\/content>\n<\/prestashop>\n<\/pre>\n\n\n\n
Dans l'administration on peut \u00e9galement voir que l'image est bien affich\u00e9e<\/p>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
Mettre \u00e0 jour une image produit<\/h3>\n\n\n\n
Lorsqu'on souhaite mettre \u00e0 jour une image produit l'url \u00e0 appeller est la m\u00eame que lorsque souhaite afficher l'image mais cette fois-ci avec la m\u00e9thode PUT<\/strong> 
On va donc mettre \u00e0 jour l'image pr\u00e9c\u00e9dente<\/p>\n\n\n\n
\/**\n * Mise \u00e0 jour d'une image existante\n * images\/products\/id_product\/id_image\n *\/\n$ch = initCurl('images\/products\/19\/24?ps_method=PUT');\ncurl_setopt($ch, CURLOPT_POST, true);\ncurl_setopt($ch, CURLOPT_POSTFIELDS, array(\n        'image' => new CurlFile('\/chemin\/absolu\/ver\/image.png')\n    )\n);\n$result = curl_exec($ch);\nprint_r($result);\ncurl_close($ch);\n<\/pre>\n\n\n\n
Je n'ai pas trouv\u00e9 d'utilit\u00e9 \u00e0 la r\u00e9ponse, en revanche on peut voir que l'image a bien \u00e9t\u00e9 mise \u00e0 jour :<\/p>\n\n\n\n
