Hey @allstarsft,

Were you able to get this resolved? When I visited this URL, I’m getting a 404 error now:

https://www.allstars.com.sg/display/monitor/lg-27gn600-27gn600-b-27-inch-ultragear-fhd-ips-gaming-monitor-with-amd-freesync%c2%99-premium-144hz-ips-hdr10-color-calibrated-8bits-color-srgb-99-g-sync-compatible-dp-v1-4%C3%971-hdmi-2-0x2-he/

If it’s still happening, can you send over an updated URL for us to take a look at?

Thanks!

Have not done anything yet.

The link u used is different from my original one.

https://www.allstars.com.sg/display/monitor/lg-27gn600-27gn600-b-27-inch-ultragear-fhd-ips-gaming-monitor-with-amd-freesync%c2%99-premium-144hz-ips-hdr10-color-calibrated-8bits-color-srgb-99-g-sync-compatible-dp-v1-4×1-hdmi-2-0x2-he/

Then that means all similar product pages will be the same…

Any coding guide on how to solve this?

Tried this coding but it didn’t work :

add_action('wp_insert_post_data', 'custom_process_Permalink');
/**
* Processes the permalink so we can remove any characters that may cause a problem when communicating
* with the API.
*
* @param array $data The array of information about the post.
* @return array $data The data without the malformed information in the post name for the URL.
*/
function custom_process_Permalink($data)
{
if (!in_array($data['post_status'], array('draft', 'pending', 'auto-draft'))) {
$data['post_name'] =
preg_replace(
'/(%ef%b8%8f|?|?|?|™|®|©|?|?|?)/',
'',
$data['post_name']
);
}
return $data;
}

Lets try with another product page link : This 2 items is out of stock for now, so we can have some troubleshooting with it.

https://www.allstars.com.sg/pc/pc-notebook/asus-rog-zephyrus-g14-ga401qm-rtx30601-with-anime-matrix%c2%99-warranty-2years-with-asus-sg/

Had to manually edit the earlier LG item now to remove the TM, as that is a new item with stock.

Hello @allstarsft ,

I believe you are trying to update all products having the trademark characters in their permalink so that those special characters are removed, right?

I do not have a working code available to update all permalinks and remove a specific character. However, this plugin seems to have a similar feature: Remove Special Characters From Permalinks. You might need the Pro version if you want to update all permalinks in one go.

Please note that this is a third-party plugin so we are unable to guarantee if this will be sufficient for your need. You may want to ask the plugin’s developer in their support forum: https://www.ads-software.com/support/plugin/remove-special-characters-from-permalinks/

I will keep the thread open to see if someone else can chime in with a better solution.

Thank you ??

Thanks for your reply, @rur165 .

I tried that plugin before, and seems didn’t do what I wanted.

Basically I need to remove the special characters only in the Permalinks.

Retain the Trademark / Registration (TM)/ (R) on the Product Title.

And it has to help me to remove the special characters for existing products, and also prevent future new products from including the special characters into the permalinks.

I’ve managed to remove the TM (Trademark symbol) from those Product Names’ Slug/Permalinks.

But hopefully future the above coding can help me to remove it from new Product Names.

The way I do it for these existing ones :

Someone in the Woocommerce Community Facebook group taught me this.

Use Better Search and Replace plugin. (Before that has to make sure Database is backed up in case.)

And the TM text in the links actually doesn’t show TM but this: %c2%99 — in WP_posts table, search for %c2%99 and replace field “empty”.

Somehow for (R) Registered Symbol, the permalinks already don’t have it there, so only the TM Symbol have to remove.

## Can anyone assist to confirm the coding above — can that solve future issue?

add_action('wp_insert_post_data', 'custom_process_Permalink');
/**
* Processes the permalink so we can remove any characters that may cause a problem when communicating
* with the API.
*
* @param array $data The array of information about the post.
* @return array $data The data without the malformed information in the post name for the URL.

function custom_process_Permalink($data)
{
if (!in_array($data['post_status'], array('draft', 'pending', 'auto-draft'))) {
$data['post_name'] =
preg_replace(
'/(%ef%b8%8f|?|?|?|™|®|©|?|?|?)/',
'',
$data['post_name']
);
}
return $data;
}

Hi @allstarsft,

Glad to hear that you got some insights in the Woocommerce Community Facebook group. This forum is intended to support the default functionality of WooCommerce and for this type of development-oriented questions, you’re more likely to get input by asking in the WooCommerce Developer Slack or Advanced WooCommerce Facebook group. As those communities are both frequented by developers.

However, I’m going to leave it open for a bit to see if anyone is able to chime in to help you out.

Thanks.

Hi there,

It’s been a while since we last heard back from you. I’m going to mark this thread as resolved.

Hopefully, the above information was helpful. If you have further questions, please feel free to open a new topic.

Cheers.
