如何修复Magento致命错误Call to a member function toOp_magento教程_php教程

当您尝试编辑的产品，类别或管理属性在Magento 后台，有时会显示下面的错误消息（显示空白页面如果显示错误消息被禁用）在Magento 升级或安装扩展后:

PHP Fatal error: Call to a member function toOptionArray() on a non-object in app/code/core/Mage/Adminhtml/Block/System/Config/Form.php on line 289

Magento Fatal error Call to a member function toOptionArray on a non-object

这一问题的最可能原因是不是升级Mage_Core_Adminhtml包或升级包但旧代码由编译器缓存。

if ($e->source_model) {

$sourceModel = Mage::getSingleton((string)$e->source_model);

if ($sourceModel instanceof Varien_Object) {

$sourceModel->setPath($path);

}

$field->setValues($sourceModel->toOptionArray($fieldType == 'multiselect'));

}

一步 2:Replace 上面与下面的代码：

if ($e->source_model) {

$sourceModel = Mage::getSingleton((string)$e->source_model);

if ($sourceModel instanceof Varien_Object) {

$sourceModel->setPath($path);

}

if(is_object($sourceModel)){

$field->setValues($sourceModel->toOptionArray($fieldType == 'multiselect'));

} else {

Mage::log($e->source_model);

}

希望此解决方案可以帮助您解决这个问题！
