Position category via webservice

[blufix79]

Goodmorning

 

They are grappling with the ordering of categories using webservices. I expected it to work on passing "position" the value of the position which I would assume the law category. Instead it always moved as the last.

Checking the code, I noticed that the update method always performs a addPosition when called via service. This happens even if not explicitly the step position value, but keep the one currently set in the category. Anyone have any idea why there is this logic?

 

Here is the part of the update code, the PrestaShop version 1.6.1.4, but this behavior have also been found in successive versions.

 

// If the parent category was changed, we don't want to have 2 categories with the same position
        if (!isset($changed)) {
            $changed = $this->getDuplicatePosition();
        }
        if ($changed) {
            if (Tools::isSubmit('checkBoxShopAsso_category')) {
                foreach (Tools::getValue('checkBoxShopAsso_category') as $id_asso_object => $row) {
                    foreach ($row as $id_shop => $value) {
                        $this->addPosition((int)Category::getLastPosition((int)$this->id_parent, (int)$id_shop), (int)$id_shop);
                    }
                }
            } else {
                foreach (Shop::getShops(true) as $shop) {
                    $this->addPosition((int)Category::getLastPosition((int)$this->id_parent, $shop['id_shop']), $shop['id_shop']);
                }
            }
        }

I would like to manage the ordering of the category among the categories appertenenti at the same level. Eg:

ParentCategory |-Subcategory1 - position 1 |-Subcategory2 - position 2 |-Subcategory3 - position 3 |-Subcategory4 - position 4 |-Subcategory5 - position 5

I would like to move the category with position 2 instead of 3, but via webservices category is always moved to the end and I find myself in this situation:

ParentCategory
 |-Subcategory1 - position 1
 |-Subcategory3 - position 2
 |-Subcategory4 - position 3
 |-Subcategory5 - position 4
 |-Subcategory2 - position 5 

This behavior occurs even if I change only the name of the category, for example, or even though the reference as well as the recovery, without changing anything. It is always moved to last.

 

Does anyone know why this logic?

 

Thank you

hello,

i just want change category name by webservice 

I dont want change position but when i change name or set position Webservice is set position category modified at botton of list 

my code look like this

 

$opt = [
      'resource' => 'categories',
      'id' => $id,
    ];
    $xml = $this->webService->get($opt);
    $resources_categ = $xml->children()->children();

    unset($resources_categ->position); // set or unset doesn't workd
    
    unset($resources_categ->level_depth); //must remove because webservice return 400 level_depth not writable. Please remove this attribute of this XML
   unset($resources_categ->nb_products_recursive);// must remove

    $resources_categ->doNotRegenerateNTree = true;// it doesn't work

    $resources_categ->name->language[0][0] = $name; //change new name
    $resources_categ->link_rewrite->language[0][0] = Tools::str2url($name);

    $return = $this->webService->edit([
      'resource' => 'categories',
      'id' => $id,
      'putXml' => $xml->asXML(),
    ]);

I look for in class Category.php

// If the parent category was changed, we don't want to have 2 categories with the same position
        if (!isset($changed)) {
            $changed = $this->getDuplicatePosition();
        }
        if ($changed) {
            if (Tools::isSubmit('checkBoxShopAsso_category')) {
               ...............
            } else {
                foreach (Shop::getShops(true) as $shop) {
                    $this->addPosition((int)Category::getLastPosition((int)$this->id_parent, $shop['id_shop']), $shop['id_shop']);
                }
            }
        }

variable $changed is always = true because when we change the name or change position, it will have the same position so the position category is modified to the last position of the same parent. 

There is a way to change the name of the category by web service without changing position?
and change position in the category with recalculate all siblings
