Magento remove images of deleted products

Clean up not used Magento images

Magento unfortunately does not remove images of a product unfortunately if the product is removed. The following script checks all the images and checks if it’s still present in the database of Magento. If not, it deletes the image. Use the following code:

<?php

$mageFilename = 'app/Mage.php';
require_once $mageFilename;

Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);
umask(0);

Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

set_time_limit(0);
ini_set('memory_limit','1024M');

$media = Mage::getBaseDir('media').'/catalog/product';

echo "Query database for images …\n";
$query = "SELECT value FROM catalog_product_entity_media_gallery";
$data = Mage::getSingleton('core/resource')->getConnection('core_read')->fetchAll($query);

$dbData=array();
foreach($data as $item){
  $dbData[$item['value']]=$item['value'];
}

echo "Images found in database:".count($dbData)."\n";

echo "Search images in media directory …\n";
$images = findFiles($media, array('jpg'));
echo "Images found under directory ($media):".count($images['jpg'])."\n";

echo "Start removing images …\n";
$removedCount=0;
$skippedCount=0;
foreach($images['jpg'] as $image) {
  if(strpos($image,'cache')!==false)
  {
    //echo "Skip cached image : $image\n";
    continue;
  }

  $imageCleanup = str_replace($media,"",$image);
  if(isset($dbData[$imageCleanup]))
  {
    echo "Skip image is in database : $image\n";
    $skippedCount++;
    continue;
  }
  else
  {
    echo "Remove image : $image\n";
    //if($testrun==false) unlink($image);
    $removedCount++;
  }
}

echo "Done, removed $removedCount images and skipped $skippedCount images.\n";

function findFiles($directory, $extensions = array()) {
  function glob_recursive($directory, &$directories = array()) {
    foreach(glob($directory, GLOB_ONLYDIR | GLOB_NOSORT) as $folder) {
      $directories[] = $folder;
      glob_recursive("{$folder}/*", $directories);
    }
  }
  glob_recursive($directory, $directories);
  $files = array ();
  foreach($directories as $directory) {
  foreach($extensions as $extension) {
  foreach(glob("{$directory}/*.{$extension}") as $file) {
  $files[$extension][] = $file;
}
}
}
return $files;
}

?>

Clean up Magento space: could save a lot of GBs

In my case, I tried the script for a store with 40K images of which 10K were not used. This is a disk space reduction of a few Gigabytes.

Final word

This script is thanks to a comment on RapidCommerce. If you use the script, that’s on your own responsibility. Try it out on a staging server and make a backup in advance. Cheers!



Magento admin category tree shows no sub categories

Ever had that the category tree does not show specific subcategories that are present though?

Than follow these steps:

1. Make a backup for if anything goes wrong (running all the steps is on your own risk of course).

2. Run this query

SELECT c.entity_id, c.children_count as original_children_count, COUNT(c2.children_count) as `children_count`, c.level as original_level, (LENGTH(c.path)-LENGTH(REPLACE(c.path,'/',''))) as `level`
FROM catalog_category_entity c
LEFT JOIN catalog_category_entity c2 ON c2.path like CONCAT(c.path,'/%')
GROUP BY c.path

3. Check if there are still minus children_count categories with:

SELECT c.entity_id, c.children_count as original_children_count, COUNT(c2.children_count) as `children_count`, c.level as original_level, (LENGTH(c.path)-LENGTH(REPLACE(c.path,'/',''))) as `level`
FROM catalog_category_entity c
LEFT JOIN catalog_category_entity c2 ON c2.path like CONCAT(c.path,'/%')
GROUP BY c.path

If anything went right, it should show a + sign before the category in the category tree in the Magento admin again. Good luck

This error is likely caused by a category copy/duplicate plugin.

Fixing “Front controller reached 100 router match iterations”

Ever got the bug: “Front controller reached 100 router match iterations”? Solve it as follows:

1. You can get more information by going to Magento Core file app/code/core/Mage/Core/Controller/Varien/Front.php, find there lines:

while (!$request-&gt;isDispatched() &amp;&amp; $i++&lt;100) {
foreach ($this-&gt;_routers as $router) {
if ($router-&gt;match($this-&gt;getRequest())) {
break;
}
}
}

Replace with:

Mage::log('----Matching routers------------------------------');
Mage::log('Total ' . count($this-&gt;_routers) . ': ' . implode(', ', array_keys($this-&gt;_routers)));
while (!$request-&gt;isDispatched() &amp;&amp; $i++&lt;100) {
Mage::log('- Iteration ' . $i);
$requestData = array(
'path_info' =&gt; $request-&gt;getPathInfo(),
'module' =&gt; $request-&gt;getModuleName(),
'action' =&gt; $request-&gt;getActionName(),
'controller' =&gt; $request-&gt;getControllerName(),
'controller_module' =&gt; $request-&gt;getControllerModule(),
'route' =&gt; $request-&gt;getRouteName()
);

$st = '';
foreach ($requestData as $key =&gt; $val) {
$st .= "[{$key}={$val}]";
}
Mage::log('Request: ' . $st);
foreach ($this-&gt;_routers as $name =&gt; $router) {
if ($router-&gt;match($this-&gt;getRequest())) {
Mage::log('Matched by "' . $name . '" router, class ' . get_class($router));
break;
}
}
}

Possible solution solving “Front controller reached 100 router” bug

What happened in my case? I opened the var/log/system.log file and there was downtime between 5 and 6. So there was a blankage between 5 and 6. The last log holds on 05:10, than the site went out:

2014-12-03T05:09:59+00:00 DEBUG (7): ----Matching routers------------------------------
2014-12-03T05:09:59+00:00 DEBUG (7): Total 7: admin, standard, cms, blog, default
2014-12-03T05:09:59+00:00 DEBUG (7): - Iteration 1
2014-12-03T05:09:59+00:00 DEBUG (7): Request: [path_info=/admin/][module=][action=][controller=][controller_module=][route=]
2014-12-03T05:10:02+00:00 DEBUG (7): Matched by "admin" router, class Mage_Core_Controller_Varien_Router_Admin
2014-12-03T05:10:02+00:00 DEBUG (7): - Iteration 2
2014-12-03T05:10:02+00:00 DEBUG (7): Request: [path_info=/admin/][module=admin][action=login][controller=index][controller_module=Mage_Adminhtml][route=adminhtml]
2014-12-03T05:10:02+00:00 DEBUG (7): Matched by "admin" router, class Mage_Core_Controller_Varien_Router_Admin

So search for the last entry before the outage. In my case there was an admin route problem. I solved it by changing the admin url in app/etc/local.xml (so far, so good). I’ll keep you updated if the outage will come again.

Magento 1.8 add to url via url query

Would like to add a product via an url like (as described in this Mage article):

<?
echo "
<form action='/checkout/cart/add/product/" . $id . "/form_key/'>
<input type='submit' value='In Cart' />
</form>";
?>

This doesn’t work in Magento 1.8 unfortunately, because of the new form_key system. You can provide an hidden form_key field. Unfortunately this didn’t work in my case. Best way is to omit the form_key security for add to cart querystrings. This can be solved with this rewrite plugin:

https://github.com/deivisonarthur/Inovarti_FixAddToCartMage18/

Good luck!

Magento not finding or showing right product images

Problem: the wrong image is shown compared to the image you inserted. Possible errors:

  • Check per product all the store view images. Maybe it crosses with your desired image.
  • Rebuild the image cache
  • Check permissions on the directory
  • Check whether there is an image with the same name already in the media file. Also check whether the problem is due to case insensitivity
  • Reindex the catalog product structure. This makes sure that the right product image is linked and shown

UPDATE: Magento showing image in frontend, but not in backend

Solution: I probably found the solution now. The image is shown in the frontend, but not in the backend. Probably this is a solution: http://www.blog.magepsycho.com/how-to-fix-the-issue-product-images-missing-in-backend-but-not-in-frontend/ . It is a script that checks for ‘damages’ in the table, which is the reason why an image doesn’t show.

UPDATE2: Multistore shows wrong/different images per store

How to get back the images and reset all the images

An extension on the above update is my own customization on the script. It gets back images that do show up in the frontend but not in the backend or when wrong/different images are shown among the various storeviews.

Module error message: MediabrowserUtility is not defined

If you install a custom module in Magento it could lack the TinyMce Mediabrowser. You get the following message then:

error: error in [unknown object].fireEvent():

event name: open_browser_callback

error message: MediabrowserUtility is not defined

How to fix this?

Quick fix

In /app/design/adminhtml/default/default/layout/YOURMODULE.xml add:

<reference name="head">
            <action method="setCanLoadExtJs"><flag>1</flag></action>
            <action method="addJs"><script>mage/adminhtml/variables.js</script></action>

        </reference>

Or change to

Long solution (may not work)

In your /YOURMODULE/etc/config.xml you have:

 
  &lt;cms_wysiwyg_config_prepare&gt;

      &lt;variable_observer&gt;
        core/variable_observer
        prepareWysiwygPluginConfig

In Block/Adminhtml/YOURMODULE/Edit.php

protected function _prepareLayout() {

    if (Mage::getSingleton('cms/wysiwyg_config')-&gt;isEnabled()) {
        $this-&gt;getLayout()-&gt;getBlock('head')-&gt;setCanLoadTinyMce(true);
        $this-&gt;getLayout()-&gt;getBlock('head')-&gt;setCanLoadExtJs(true);
    }
}

Then in the top of Block/Adminhtml/YOURMODULE/Edit/Tab/Form.php

 protected function _prepareForm() {
            $form = new Varien_Data_Form();
            $this-&gt;setForm($form);
            $wysiwygConfig = Mage::getSingleton('cms/wysiwyg_config')-&gt;getConfig(array('add_variables' =&gt; false,
         'add_widgets' =&gt; false,

          'files_browser_window_height'=&gt; (int) Mage::getConfig()-&gt;getNode('adminhtml/cms/browser/window_height')
         ));

Further down:

                                    'label'     =&gt; Mage::helper('WHATEVER')-&gt;__('Content'),
                                    'title'     =&gt; Mage::helper('WHATEVER')-&gt;__('Content'),

Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction

When having trouble with the error: “Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction” or when your place order / order confirmation gets stuck.

Fixing the order process getting stuck:

According to the Magento Forum, in MySQL, try:
