[Beta] Dynamic Facebook and Twitter Meta Tags

[jcocking]

I have reviewed the various suggestions.

Like Button/Meta Tags for ALL Individual Posts
This is technically feasible with a clean phpBB install. I run phpBB-SEO and this request is not feasible with this enhancement. phpBB-SEO has a URL duplicate content check feature. It will prevent duplicate content from showing up with different urls.

In order to make this work, you will have unique meta tags for each post. If your page has 10 posts, each post will have 10 different unique meta tags. The content of each page would be identical. The search engines would look at 10 pages with different URLs, but all have the same content. This is not recommended in the SEO World. I can walk some one through the logic, but I can not use this feature and do not want to dedicate the time develop and maintain at this time.

First Image/Last Image
This can be done and I will add it to the queue. This will give you the last image posted in the topic.

ACP Control/Permissions
There is only one switch at this time, so I will keep it simple with a true/false variable in the code. I like to avoid building ACP controls. This will also remove the permission options.

Multiple Images
Facebook does not support multiple images.

If I missed something, please let me know.

Nice to see that you are supporting this great mod ,thank you. And with multiple images i refer to be able to choose one image from the images that are in the topic not to post multiple images at one. For example, if I don't set dynamic meta tags, sometimes I'm able to choose one picture to be posted on the wall from 3 or 4 random pictures from that topic. Anyway ..the last image from the 1st post of the topic would be great too.

i'm thinking is it possible to let it also grab a youtube video that's posted with bbcode in the first post to share on facebook or even twitter.

bbcode:

Code: Select all

[youtube]http://youtu.be/KzI8xldVGBY[/youtube]

so the meta's would be something like this

Code: Select all

<meta property="og:type" content="video">
<meta property="og:image" content="http://i4.ytimg.com/vi/KzI8xldVGBY/hqdefault.jpg">
<meta property="og:video" content="http://youtu.be/KzI8xldVGBY">
<meta property="og:video:type" content="application/x-shockwave-flash">

Hi, still nothing about posting the last image from 1st post instead of first ?

I get this error when viewing a topic with debug on:

Review the installation instructions. Something has been missed. Without viewing your code, it is hard to understand what is at line 1423, 4772, 4774, 4775, 4776. This is like asking me to fix your car in the dark, from a distance, based on the what it see.

Other projects in the way. Always the downside of opensource software. Not forgotten, just not a priority at this time.

I wasn't sure if you'd have an idea of what's wrong from the debug error or not hence awaiting reply...But now that you ask about the code...

Review the installation instructions.

Pretty sure all is installed as it should be, have skimmed over and can't see anything done incorrectly.

I wasn't sure if you'd have an idea of what's wrong from the debug error or not hence awaiting reply...But now that you ask about the code...

Review the installation instructions.

Pretty sure all is installed as it should be, have skimmed over and can't see anything done incorrectly.

The viewtopic flags are minor. It is indicating the variables were not defined before using them. It does not impact functionality, but will fix in the next release.

The functions.php errors are caused by debug sending a result to the screen before the headers were entered. As soon as I resolve the first two, the rest go away automagically.

Spot on cheers Jeff.

New Version (0.3.0) was posted today.

Bug Fixes:

• Resolved issue with undeclared variables. $sMetaDescription and $sMetaImage.

Enhancements:

• Added support to select first or last photo to be used. Option is controlled by true/false option in code.
• Added support for [video] bbcode. Will create og:video if a video is present in post.

Moved all code to GitHub for easier download and usage.

Nice to see that you are supporting this great mod ,thank you. And with multiple images i refer to be able to choose one image from the images that are in the topic not to post multiple images at one. For example, if I don't set dynamic meta tags, sometimes I'm able to choose one picture to be posted on the wall from 3 or 4 random pictures from that topic. Anyway ..the last image from the 1st post of the topic would be great too.

The tools you are referencing are javascript tools. They are built for interactive/real time posting to Facebook. This tool is to provide the necessary meta tags for Twitter and Facebook to use.

jeff

[jcocking]

i'm thinking is it possible to let it also grab a youtube video that's posted with bbcode in the first post to share on facebook or even twitter.

bbcode:

Code: Select all

[youtube]http://youtu.be/KzI8xldVGBY[/youtube]

so the meta's would be something like this

Code: Select all

<meta property="og:type" content="video">
<meta property="og:image" content="http://i4.ytimg.com/vi/KzI8xldVGBY/hqdefault.jpg">
<meta property="og:video" content="http://youtu.be/KzI8xldVGBY">
<meta property="og:video:type" content="application/x-shockwave-flash">

Implemented with new release. We used the [video] bbcode. If you have an alternate bbcode, the code will need to be modified to look for youtube versus video. Look at the first section of code referenced for viewtopic.php. Look for [video and [/video to be replaced.

Hi Jeff,

Just installed the latest version with $first_image set to false and I get this whenever viewing page 1 of any topic: (EDIT: Setting to 'true' fixes the error)

Hi Jeff,

Just installed the latest version with $first_image set to false and I get this whenever viewing page 1 of any topic: (EDIT: Setting to 'true' fixes the error)
