Magento 1.9.2 dan php7 - kesalahan unggahan gambar

Saya hanya menguji Magento 1.9.2 dengan Php 7. Semua tampak berfungsi, tetapi tiba-tiba saya mencoba mengunggah gambar untuk produk. Saya mendapat kesalahan seperti di bawah ini:

Fatal error</b>:  Uncaught Error: Function name must be a string in /home/admin/domains/store.com/public_html/dev/lib/Varien/File/Uploader.php:259
Stack trace:

Adakah yang tahu cara memperbaikinya?

Fungsi terpengaruh di upload.php pada baris sekitar 259

protected function _validateFile()
    {
        if ($this->_fileExists === false) {
            return;
        }

        //is file extension allowed
        if (!$this->checkAllowedExtension($this->getFileExtension())) {
            throw new Exception('Disallowed file type.');
        }
        //run validate callbacks
        foreach ($this->_validateCallbacks as $params) {
            if (is_object($params['object']) && method_exists($params['object'], $params['method'])) {
                $params['object']->$params['method']($this->_file['tmp_name']);
            }
        }
    }

http://php.net/manual/de/migration70.incompatible.php https://wiki.php.net/rfc/uniform_variable_syntax

Karena sintaks variabel seragam kode sekarang ditafsirkan secara ketat dari kiri ke kanan.

Garis

$params['object']->$params['method']($this->_file['tmp_name']);

seharusnya

$params['object']->{$params['method']}($this->_file['tmp_name']);

Anda dapat menemukan ikhtisar semua file untuk diedit dalam jawaban ini .

Selain jawaban di atas, jangan lupa untuk memeriksa file:

\ termasuk \ src \ Varien_File_Uploader.php pada baris 259

Menggantikan

$params['object']->$params['method']($this->_file['tmp_name']);

dengan

$params['object']->{$params['method']}($this->_file['tmp_name']);
