Magento 1.7 Patch – Can’t Edit Product After Installing Patch SUPEE-8788

Have you switched off and cleared compilation?

via the console/ssh you can use

$ php -f shell/compiler.php -- disable

$ php -f shell/compiler.php -- clear

$ php -f shell/compiler.php -- compile

$ php -f shell/compiler.php -- enable

might need the fourth line...not sure.

It might be a problem with the line that comes before the code you showed

$routersInfo = Mage::app()->getStore()->getConfig(self::XML_STORE_ROUTERS_PATH);

Note: I had a similar problem where the admin was blank, however that turned out to be a file in a module that was overriding one of the core files - but this is not in your case. Just in case others look at this with that issue.

Mage_Adminhtml_Block_Media_Uploader is deprecated on after SUPEE-8788 (and 1.9.3). Thus there are several backward incompatibility changes which breaks module using the uploader.

I first thought a small change would fix it but there's actually way more to do.

Make a module using the gallery compatible with 1.9.2 and 1.9.3

So if you're a module provider, you don't want to have two different versions of your module for 1.9.2 and 1.9.3. Here's how to make your code compatible with both:

In your block _prepareLayout method you need to do the following:

Replace:

 $this->getUploader()->getConfig()
            ->setUrl($url)
            ->setFileField('image')
            ->setFilters(array(
                'images' => array(
                    'label' => Mage::helper('adminhtml')->__('Images (.gif, .jpg, .png)'),
                    'files' => array('*.gif', '*.jpg','*.jpeg', '*.png')
                )
            ));

With:

    if (class_exists("Mage_Uploader_Block_Abstract")) {
        // PATCH SUPEE-8788 or Magento 1.9.3
        $this->getUploader()->getUploaderConfig()
            ->setFileParameterName('image')
            ->setTarget($url);

        $browseConfig = $this->getUploader()->getButtonConfig();
        $browseConfig
            ->setAttributes(
                array("accept"  =>  $browseConfig->getMimeTypesByExtensions('gif, png, jpeg, jpg'))
            );
    } else {
        $this->getUploader()->getConfig()
            ->setUrl($url)
            ->setFileField('image')
            ->setFilters(array(
                'images' => array(
                    'label' => Mage::helper('adminhtml')->__('Images (.gif, .jpg, .png)'),
                    'files' => array('*.gif', '*.jpg','*.jpeg', '*.png')
                )
            ));
    }

As you can see I'm using class_exists to check whether SUPEE-8788 or Magento 1.9.3 is applied.

Then in your gallery.phtml you need to replace:

var <?php echo $_block->getJsObjectName(); ?> = new Product.Gallery('<?php echo $_block->getHtmlId() ?>', <?php if ($_block->getElement()->getReadonly()):?>null<?php else:?><?php echo $_block->getUploader()->getJsObjectName() ?><?php endif;?>, <?php echo $_block->getImageTypesJson() ?>);

With:

<?php if (class_exists("Mage_Uploader_Block_Abstract")): ?>
    var <?php echo $_block->getJsObjectName(); ?> = new Product.Gallery('<?php echo $_block->getHtmlId() ?>', <?php echo $_block->getImageTypesJson() ?>);
<?php else: ?>
    var <?php echo $_block->getJsObjectName(); ?> = new Product.Gallery('<?php echo $_block->getHtmlId() ?>', <?php if ($_block->getElement()->getReadonly()):?>null<?php else:?><?php echo $_block->getUploader()->getJsObjectName() ?><?php endif;?>, <?php echo $_block->getImageTypesJson() ?>);
<?php endif; ?>

Then for the layout file, you can do it like this:

<reference name="head">
    <action method="addJs"><file helper="module/getFlowMin" /></action>
    <action method="addJs"><file helper="module/getFustyFlow" /></action>
    <action method="addJs"><file helper="module/getFustyFlowFactory" /></action>
    <action method="addJs"><file helper="module/getAdminhtmlUploaderInstance" /></action>
</reference>

Replace module with your helper class identifier and in your module Data.php helper add the following:

protected function _isNoFlashUploader()
{
    return class_exists("Mage_Uploader_Block_Abstract");
}

public function getFlowMin()
{
    return $this->_isNoFlashUploader() ? "lib/uploader/flow.min.js" : null;
}

public function getFustyFlow()
{
    return $this->_isNoFlashUploader() ? "lib/uploader/fusty-flow.js" : null;
}

public function getFustyFlowFactory()
{
    return $this->_isNoFlashUploader() ? "lib/uploader/fusty-flow-factory.js" : null;
}

public function getAdminhtmlUploaderInstance()
{
    return $this->_isNoFlashUploader() ? "mage/adminhtml/uploader/instance.js" : null;
}
