T_PAAMAYIM_NEKUDOTAYIM Erreur après remplacement de CButtonColumn

Question

J'ai remplacé la classe CButtonColumn et le code fonctionnait parfaitement sur localhost(windows) , mais lorsque je l'ai téléchargé sur le serveur Linux, j'ai eu cette erreur :

Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in /home/xxx/public_html/protected/components/GridView/XCButtonColumn.php on line 65

J'ai lu ce que signifie "T_PAAMAYIM_NEKUDOTAYIM", ça veut dire "::"lien ici, mais je n'ai pas compris ce que je pouvais faire pour résoudre le problème.

ligne 65 :

if (is_array($modelClass::model()->primaryKey))

Voici mon code :

<?php

    public $updateButtonImageUrl = '';
    public $updateButtonHtml;
    public $deleteButtonOptions = array('class' => 'btn btn-default tip delete');
    public $deleteButtonImageUrl = '';
    public $deleteButtonHtml;
    public $showImage = false;
    public $showHtml = true;

    protected function renderButton($id, $button, $row, $data)
    {

Merci d'avance

Answer 1

Merci d'abord à Benka d'aider, le problème est dans la version PHP et PHP 5.2 ne supporte pas cette ligne:

if (is_array($modelClass::model()->primaryKey))

Donc, pour travailler sur PHP 5.2 Je l'ai changé pour être:

if (is_array(CActiveRecord::model($modelClass)->primaryKey))

Answer 2

devrait être -> au lieu de ::

if (is_array($modelClass->model()->primaryKey))
