  • WooCommerce emails add reply to header

    WooCommerce emails add reply to header

    A client was having issues with bounce back due to customers entering incorrect email addresses, so I updated the outbound email address used by WooCommerce to “[email protected]”, this meant any bounce backs would go to a null mailbox instead of to their mains “[email protected]” mailbox. However, this meant when customers hit reply, it would reply to the noreply@ mailbox. Using this code, I was able to set a Reply-To header, so customers could still reply to emails.

    Code

    Drop this into your functions.php file and edit as required.

  • WordPress include private pages in parent dropdown

    WordPress include private pages in parent dropdown

    WordPress only includes published pages in the parent page dropdown, I ran into an issue where both parent and child page were made private so work could be done to the pages, the child pages when edited lost their parent relationship, due to the parent page no longer appearing within the “Parent” dropdown.

    Why would you need this?

    In my case we wanted to make some changes to the existing pages but needed to do these changes in private until all where complete, it was not until after we re-published the pages, we found the child pages where no longer link to the parent.

    Fix

    Let’s add the private and pending pages to the parent dropdown menu, allowing us to pre-create pages and child / parent relationships without having to already have published the pages.

  • SuiteCRM – clear / reindex search index

    SuiteCRM – clear / reindex search index

    Came across a problem with a SuiteCRM where the search was not working correctly, returning none or unrelated results. SuiteCRM relies on an indexing service called Lucene, which handles indexing for advanced searches, as in my case, this needs to be full reindexed to work correctly.

    1. Lock Files

    When Lucene begins indexing it generates lock files, normally found under modules/AOD_Index/Index/Index with the extension .lock, it is save to delete these files if they are old (have an old time stamp), sometimes this is enough to fix the issue, as previous indexing attempts max have failed and left the lock file, stopping future indexing processes from starting. First try, removing these lock files and wait and see if the indexing processes continue / repair them selfs.

    2. Full Reindexing

    I would recommend you do a full backup of the modules/AOD_Index directory before starting, as well as a backup of the database.

    Also temperarly stop cronjobs from running, as we dont want the cron indexer to kick in during this clearing process.

    1. Rename index folder (can be deleted after)

    From your SuiteCRM root directory:

    mv modules/AOD_Index/Index/Index modules/AOD_Index/Index/Index.BACKUP

    We are renaming your current (old) index to Index.BACKUP, you can delete this later once you are sure everything is resolved.

    2. Empty Table

    Now delete all rows from the table aod_index

    3. Schedules

    Make sure the Optimise AOD Index and Perform Lucence Index are running as part of the schedule.

    4. Wait

    Make sure you have re-enabled your cronjob and wait for the indexes to rebuild. This will take a long time, but you can monitor the rebuilding process with the below command. Once it has stabilised, it should be complete.

    watch du -h modules/AOD_Index/Index/Index

  • WordPress disable XMLRPC.php for increased security

    I have recently been having a few issues with bots and malicious attacks trying to breach WordPress websites via brute force attacks. From my experience 90% of the websites, I have built or worked on never utilise the xmlrpc service, which is included with WordPress, due to this I decided to simply block any access to this service via Apache, which fixes a number of security related issues.

    Code

    Place this in your websites .htaccess file to take effect, then simply browser to domain.com/xmlrpc.php and you now get an access denied message.

    What is XMLRPC?

    The xmlrpc.php allows remote access to your WordPress site, it allows various tools and publishing applications to control and manage content from outside of the normal WordPress admin. For example, a publishing tool may allow you to write new blog posts using an alternative tool (instead of the WordPress admin).

    Do I need it?

    If you do not use any tools / services which utilise xmlrpc, then you do not need it and can apply the block in this post. For example, if you use the WordPress app to manage your website from your phone then you will need to keep XMLRPC working.

    Why block XMLRPC?

    Due to the nature of XMLRPC, it allows remote services to connect and perform actions on your website, this creates an additional security risk, and it is very common for malicious attacks to target XMLRPC with bruite-force attacks, trying to guess your password and / or access other services exposed by the XMLRPC protocol.

  • cPanel – Sender x has an outgoing mail hold. Message will be reattempted later.

    A client was having issues sending emails and receiving a number of alerts regarding delayed emails. After looking investigating a number of outbound emails where queued with a failure reason of:

    The account in question had hit the sending limits configured within cPanel and there emails where being held.

    Pre-Checks

    It is important you pre-check and make sure the hold is not legitimate such as a spam attempt / hacked site, I checked the emails being sent and due to a influx in online orders there email usage per day has significantly increased.

    1st Attempt

    Try running the following commands under sudo / root, replaceing [accountname] with the cpanel account name of the user. Then try send an email or retry sending an email in the queue.

    2nd Attempt

    The above worked for a couple accounts, but for one this did not work. There is 3 files depending on the type of block. Have a look in the following files below and remove the accountname / email address if present.

    I found my user within “/etc/outgoing_mail_suspended_users” and once removed, everything went back to normal.

    It is recommended a professional under takes these actions, please always backup existing files / configs.

  • WooCommerce admin filter products by image

    A client recently asked me to add a filter to the WooCommerce admin products list so they can filter items based on if the item had an image or not. This allowed them to easily find products which had missing images so they could correct.

    Why not take a look how to filter by on sale items?

  • WooCommerce delayed webhooks using actions scheduler

    Recently been contacted by a user who needed the ability to delay the WooCommerce webhooks by x time, this would allow other processes happening on the site to finish instead of firing the webhook straight away, for example waiting for the payment process to finalise. Delaying webhooks is not common practice, however some time special case arises!

    Take a look at actions scheduler if you wish to read more into the scheduler system used by WooCommerce.

    Code

    The following code allows you to delay several WooCommerces webhooks by a set duration (seconds) and also run in two modes.

    1. Single Webhook, creates 1 single webhook but delayed by x seconds.
    2. Multi Webhook, creates 2 webhooks, the normal webhook created by WooCommerce and a second repeat webhook which runs x seconds later.

    This code is provided as it and may require changes to work for your needs.

     

  • Fix WooCommerce webhook loop when using WooCommerce API

    Problem (Quick)

    Updating a product via the WooCommerce API would fire an update webhook, causing a loop of webhook and API activity which never ended.

    Problem

    Created a script which keeps stock levels synced between WooCommerce and a stock management system, WooCommerce WebHooks are used to set products stock levels in near real time. Using WooCommerce API new stock levels are pushed to WooCommerce, however with each API push this would trigger a product updated webhook, causing my script to reinforce the stock levels via API (causing an unlimited updating loop).

    Solution

    We can use  woocommerce_webhook_should_deliver  filter to control if a webhook should be delivered.

    The following example shows how I used the clients IP address (in this example my scripts server) to stop webhook delivery for any requests from that IP address, this allows my script to use the API and webhooks will never be delivered.

  • WooCommerce fix slow or delayed webhooks and achieve instant webhook firing

    I’ve recently been working on a project which synced data between WooCommerce and an internal warehouse system, I was utilising the WooCommerce webhooks to achieve near real time syncing between the two systems, without having the creating API scripts to poll for data on a regular basis.

    The Problem?

    There was a delay ranging from couple seconds to 1 minute, WooCommerce uses a system called actions scheduler, this is an improved wordpress cron, allowing background processing to occur within WordPress for single or recurring actions. This is great and what WooCommerce utilises for its web hook system, however it is backed by the word press cron and the next load of scheduled actions will run on the next cron run (every 1 minute).

    For this project, I needed the web hooks to fire as soon as the button was clicked, and a possible delay up to 1 minute was to long.

    Fix

    Disable async web hooks, web hooks will not fire as soon as they are created as part of the browser request.

    I would recommend you test your site after doing this change, for example order webhooks will fire when a customer creates a new order, which could lead to a slow user experience.

  • WooCommerce admin products filter by on sale

    WooCommerce admin products filter by on sale

    I needed the ability to filter the WooCommerce products list within admin by products which where on sale. This was to allow the client to easily find products they have put on offer within certain categories. The below code achieves this.

    It does need some work, as it currently ignores the on sale start and end dates, however you should be able to easily modify it for this purpose.
