How to search using Prestashop web service - search

Question

I'm trying to use Prestashop's web service to build an app for my store. For searching products, it's known that we can use
http://store_url/api/search?query=keywords&language=1
But if I search for anything, it won't give me more than 10 results. I've tried using &limit and &display. But nothing works.
If there's an alternative, please let me know.

Answer 1

I think you can try this way to search products:
http://store_url/api/products/?display=full&limit=2&filter[name]=[print]%
You can change display and limit.
It's from Prestashop web services doc.
Hope this helps anyone.

Answer 2

After much wall smashing, I've found a work around. So, the problem is in this file located at /classes/webservice,
WebserviceSpecificManagementSearch.php
Around line 87, you'll find
$results = Search::find($this->wsObject->urlFragments['language'], $this->wsObject->urlFragments['query'], 1,1, 'position', 'desc', true, false);
This the last but second argument tells the Search function that it's an ajax search. MAKING IT FALSE WILL NOT WORK.
Instead, you need to go to /classes/Search.php and find the function "find". Starting at around line 278, you'll find this:
if ($ajax)
{
$sql = 'SELECT DISTINCT p.id_product, pl.name pname, cl.name cname,
cl.link_rewrite crewrite, pl.link_rewrite prewrite '.$score.'
FROM '._DB_PREFIX_.'product p
INNER JOIN `'._DB_PREFIX_.'product_lang` pl ON (
p.`id_product` = pl.`id_product`
AND pl.`id_lang` = '.(int)$id_lang.Shop::addSqlRestrictionOnLang('pl').'
)
'.Shop::addSqlAssociation('product', 'p').'
INNER JOIN `'._DB_PREFIX_.'category_lang` cl ON (
product_shop.`id_category_default` = cl.`id_category`
AND cl.`id_lang` = '.(int)$id_lang.Shop::addSqlRestrictionOnLang('cl').'
)
WHERE p.`id_product` '.$product_pool.'
ORDER BY position DESC LIMIT 10');
return $db->executeS($sql);
}
As you can see, the results are limited by 10. So you need a way to tell the function that it's being called by the WebService. So what I did was this. It's pretty simple. Instead of
ORDER BY position DESC LIMIT 10'
use:
ORDER BY position DESC LIMIT '.(($isWS)? '10000': '10')
The variable $isWS is type Boolean. So you'll have to change the find function's declaration to this:
public static function find($id_lang, $expr, $page_number = 1, $page_size = 1, $order_by = 'position',
$order_way = 'desc', $ajax = false, $use_cookie = true, Context $context = null, $isWS = false)
Once you've done this, you can now pass in the value for $isWS from WebserviceSpecificManagementSearch. So change it to this at line 87:
$results = Search::find($this->wsObject->urlFragments['language'], $this->wsObject->urlFragments['query'], 1,1, 'position', 'asc', true, false, null, true);
Hope this helps anyone with the same problem.
