Webservice count(): Parameter must be an array or an object that implements Countable

[johnymas]

Due to this warning below webservice  will not work at all

[PHP Warning #2] count(): Parameter must be an array or an object that implements Countable (/var/www/clients/client17/web51/web/classes/webservice/WebserviceRequest.php, line 800)

 

So we have to change line 800 from

if (count(self::$shopIDs)) {

to

if (self::$shopIDs && count(self::$shopIDs)) {

 

We use the latest version of prestashop 1.7.4.3 which have to be compatible with php 7.2. ??

When I install the new prestashop 1.7.7  and it upgraded me to PHP 7.2 and I'm getting this error on the web page (picture)

this is the code on the php page 

public function hookdisplayNav2($param) {
        $id_shop = (int)Context::getContext()->shop->id;
        $staticBlocks = $this->_staticModel->getStaticblockLists($id_shop,'displayNav2');
        if(count($staticBlocks)<1) return null;
        $this->smarty->assign(array(
            'staticblocks' => $staticBlocks,
        ));
       return $this->display(__FILE__, 'views/templates/block.tpl');
    }

Im not getting any syntax error 

any help on fixing this thanks

change php version  7.1

The module "labertacticblocks" seems not to be compatible with PHP 7.2. - you should ask the developer to fix it or deactivate it

Change

if (count(self::$shopIDs)) {

to

if (@count(self::$shopIDs)) {

(just put @ before count). This will validate the expression before count acctually counts the content.

Seems to be caused by a mpodule "CustomFields" that is not compatible with your PHP version

Depends what program you are using to run websites (XAMP, LARAGON, EASYPHP). Check the preferences to switch the PHP ver.
