Post Edit History Viewer

When someone edits a post, the old message is stored in another table before the new one overwrites the old message.

Posts that have been edited will have "view edit history" displayed below the post count in the postbit.

Clicking "view edit history" allows previous versions of a post to be seen.

The postbit and postbit_legacy templates are altered using a similar method to the one used in the vbshout extension by Zero Tolerance, i.e. a search and replace. This means that no manual alterations to these templates are required.

Normally, everyone can see the post history for all the posts, however, the XML file post_hist_mods_only.xml restricts it to mods only (and the poster themselves). (Both versions should not be installed at the same time).

--------------------------------

Updated:

use post-hist_1_1b.zip

Changes

- Enable/Disable by forum
-- On/Off by forum

- Enable/Disable by usergroup
-- Can see own history: Yes/No
-- Can see everyone's history: Yes/No

- Indicates who made the edit (if it wasn't the original author)

- Workaround for unknown templates
-- Insert <<Insert Post History>> into postbit and postbit_legacy templates
-- (This is only for templates where the auto-match doesn't work)

The options are controlled by admincp.

By default, nobody can see any of the histories. At minimum, you should set the admin usergroup to see all histories.

Request

I don't know how 3.6.x products work, but if someone tries it on 3.6.x and it works, that would be good to know. I don't actually have 3.6 on our own forums, so can't test it.

Also, if you find out any bugs for < 3.6, that would be good to know too.

Install Info

The zip file contains:

bit_field_post_hist.xml -> XML for permissions
post_hist_1_1.xml -> product file

To install:

copy bit_field_post_hist.xml to /includes/xml

and install the product.

In theory, this should work as an upgrade to the previous version. However, I haven't tested that.

If you uninstall the old version and install the new version, you will lose any saved post histories.

Troubleshooting

bitfield cache
You might have to open:

yourserver.com/admincp/index.php?do=buildbitfields

This re-calculates the bitfields that have been altered. On some versions, the product installer will automatically do it.

Moderators
The postbits determine if a post is a person's own post by seeing if they have permission to edit the post. This means that if you give mods the rights to see their own post histories, then they will be able to click to see everyone elses post histories as they have the rights to edit all posts. However, the link won't have any effect as the actual viewer is restricted based on actual poster.

Usage

The XML file should add 2 options that can be set when setting up a usergroup and 1 new option for each forum.

New options for each usergroup:

Can See Post History (Yes/No)
---- Allows members of this usergroup to see all post histories

Can See Own Post History (Yes/No)
---- Allows members of this usergroup to see their own post history

New option for each forum:

Post History Displayed (Yes/No)
---- Shows post history for every post in this forum

When I restricted it to one user only this one could view the history but the link showed up for others as wellg giving them always the same version on every number...

My code looks now like

if ( $vbulletin->userinfo['usergroupid'] == 6 ) {

$vbulletin->templatecache['postbit'] =  str_replace( $insert_point,  $insert_point . $new_text , $vbulletin->templatecache['postbit'] );

$vbulletin->templatecache['postbit_legacy'] =  str_replace( $insert_point,  $insert_point . $new_text , $vbulletin->templatecache['postbit_legacy'] );

$vbulletin->templatecache['postbit'] =  str_replace( $insert_point2,  $insert_point2 . $new_text , $vbulletin->templatecache['postbit'] );

$vbulletin->templatecache['postbit_legacy'] =  str_replace( $insert_point2,  $insert_point2 . $new_text , $vbulletin->templatecache['postbit_legacy'] );
}

I meant that if you left it as default, it would have worked

The check is that those who can edit the post can also see the option.

There's definitely, some kind of problem with this hack. I just had a zillion users PM me that they could not see any posts in a thread at all!!! I disabled the plugin and everything is back to normal.

Installed and working fine for me. One minor bug: When viewing pm's it shows a linked "1" now where the "View History" is on edited posts. It does this on all pm's even before the hack was installed. It links to:

http://www.123.com/forum/showthread....editnum=1#post

Minor but could be fixed. I haven't been able to look at and fix it yet myself.

I have fixed it. The problem is that PMs use the same postbit as posts. I just had to add a check so that it doesn't display unless $post[editnums] exists.

Were you able to see the threads, or was it just other users ... it would be surprising if there was a usergroup dependant bug ?

It sounds like the postbit for showthread is broken somehow (and is crashing the postbit generator).

What version of vbulletin are you using and also have you changed the postbit template much ?

Another check that would be worth doing is to see if disabling just the plugin relating to showthread allows you to see normal threads.

If not, then check if disabling just the plugin relating to the postbit allows the you to see threads normally.

If you disable the postbit change, then it is still possible to view older versions of posts by typing in the link directly, you can use:

showthread.php?p=69841&prev_postid=69841&prev_edit num=0#post69841

to view the original version of a post that you have edited. You need to change 69841 to the postid of the post you have just edited.

It only records edited posts. Posts that aren't edited are still only stored once.
