Retrieve a resource

Now that we have retrieved a list of resources let’s see how to access the details of one resource in particular. In the XML list you can see that each individual resource as a unique ID that you can use to get its details:

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
    <customers>
        <customer id="1" xlink:href="http://example.com/api/customers/1"/>
        <customer id="2" xlink:href="http://example.com/api/customers/2"/>
    </customers>
</prestashop>

We are going to use the same get() method but provide an additional id parameter

Key Value
resource customers
id resource_id (int)

Using PrestaShopWebservice::get

try {
    // creating webservice access
    $webService = new PrestaShopWebservice('http://example.com/', 'ZR92FNY5UFRERNI3O9Z5QDHWKTP3YIIT', false);
 
    // call to retrieve customer with ID 2
    $xml = $webService->get([
        'resource' => 'customers',
        'id' => 2, // Here we use hard coded value but of course you could get this ID from a request parameter or anywhere else
    ]);
} catch (PrestaShopWebserviceException $ex) {
    // Shows a message related to the error
    echo 'Other error: <br />' . $ex->getMessage();
}

Returned data

You will receive the same xml as if you request http://example.com/api/customers/1 in your browser:

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">

Access resource fields

You can now loop through this XML object to get each customer field value, or access specific fields individually

$customerFields = $xml->customer->children();
$firstName = $customerFields->firstname;
$lastName = $customerFields->lastname;
echo 'Details for '. $firstName . ' ' . $lastName . PHP_EOL . PHP_EOL;
foreach ($customerFields as $key => $value) {
    echo $key . ': ' . $value . PHP_EOL;
}
