Tabcontrol - Fehlermeldung nach Umstellung auf PHP7.2

[damac]

Hallo.

Ich passe gerade eine Seite auf PHP 7.2 an.
Nach einem Update von Contao auf 3.5.36 bekomme ich immer folgende Fehlermeldung, wenn ich die Erweiterung Tabcontrol in den Einstellungen wieder aktiviere:

Mir sagt die Fehlermeldung leider gar nichts. Was könnte das bedeuten?

Mir sagt die Fehlermeldung leider gar nichts. Was könnte das bedeuten?

Die Fehlermeldung sagt, daß Du count() (steht in Zeile 41 von ContentTabControl.php (https://github.com/christianbarkowsk...ontrol.php#L41) auf etwas anwendest, das kein array und auch nichts ist, das Countable implementiert.

So weit, so technisch :-o

In der Zeile 41 wird count() das übergeben, was zuvor mittels

$classes = deserialize($this->tabClasses); 

ausgelesen wird. deserialize sollte einen Array erzeugen -- außer die übergebenen Daten sind "leer".

Hast Du also in Deinem Inhaltselement unter "tabClasses" etwas eingetragen/ausgewählt?

Ja, die Einstellungen wurden nicht übernommen. Ich habe sie jetzt noch mal eingefügt.

Leider aber immer noch die Fehlermeldung - nun auch im Backend

Leg dazu ein Ticket an: https://github.com/christianbarkowsky/tabcontrol/issues

[Fehrmann]

Hinweis:

$classes = deserialize($this->tabClasses, true);

gibt auf jeden Fall ein Array zurück (gegebenenfalls eben leer).

Vielleicht hilft das schon.

Ist zwar schon etwas älter, hat mir aber bei einem älteren Projekt gerade sehr geholfen.
Vielen Dank.
