BB Code Enhancements - Validate matching quote BBCode tags.

Quotes Validation

I created this modification to help alleviate the need to edit posts that have invalid/mismatched QUOTE tags. For a busy forum, correcting bad QUOTE tags can become a big problem for your moderators.

Messages (new or edited) rejected by this mod will return the member to the post submission form with the phrase: "One or more of [quote] tags are missing or mismatched. All posts are required to have proper matching quotes."

I have been running it on my board for a month or so without problems. It may run on versions older then 3.8, but I have not tested that.

I have created a number of mods for my board, this is the first one I have released!

History
1.0

Initial Version

1.1
Added plugin: newpost_preview
Added setting: Auto Preview Mode.

If active, the system will automatically put you in preview mode, and display the error message in the post area, when QUOTE mismatches are found.

Added phrase: To display CSS around "in post" error message.
Bug Fix: versions v1.0 and v1.1 (Note: fix already applied to all versions)

Memory leak causes download dialog for all browsers (for large posts). Download quotes_validation_bugfix.zip (contains: class_verifyquotes.php) and upload it. Fixes all previously installed versions.

1.2
Added Option: Style (CSS) for error message
Added Option: Bad Quotes Error Message

This will let you edit the Error Message and CSS that controls the output without having to edit the phrase directly. I left the original phrase code in place so that it will not get wiped out when you upgrade. You will have to search for the phrase (vqbc_bad_quotes_error) and copy it to the new setting.

Changed the phrase that displays the "in post" error message to work with the new options.
1.3
Bug Fix: Removed recursion and complex regular expressions. These were causing issues with large posts.
Added Option: Ignored Tags (allows you to add tags to be ignored during validation, note: noparse is always ignored)

Notes
PHP 5.0+ required.

If you are still using PHP 4 (you should upgrade). Or you can edit the class_verifyquotes.php file and remove all public and private keywords (before each function). Then edit the product-vqbc_rayj2009_v1-1.xml file and remove the PHP 5.0 dependency line.

The bug fix has already been applied to both versions. So you only have to download the latest!

And... there is a new version (1.2) that added the ability to change the error message, and the CSS that controls its display, via the options.

Nice update, thanks.

If anyone is interested I'm using this CSS to make a rounded border with a slight shadow, light yellow background and dark red text... Easily edited to your needs.

There are 3 properties needed for each rounded border (radius) and shadow... -moz is for firefox browser, -webkit is for chrome browser, and the other is for IE9 and standard web browsers.

color: darkred; background: lightyellow; border: 2px  inset red; padding: 4px; margin: 2px; -moz-border-radius: 5px;  -webkit-border-radius: 5px; border-radius: 5px;  moz-box-shadow:0 0 2px darkred; -webkit-box-shadow:0 0 2px darkred; box-shadow:0 0 2px darkred;

This is a great modification, but people occasionally will have a problem with it on our site due to the length (number of characters) of the quoted text. The limit within one set of quote tags appears to be 8281. I can add another set of quote tags around a 8281 character quote and add some more text in the outer set.

[raywjohnson]

Are you using the latest version? There was an issue with large posts in the original version.

--RayJ

[ravenscape]

it is version 1.2 that I have installed.

[xorex]

will be good if mod would have setting for exclude validate quotes inside tags

example: [code] [html] [php] e.t.c

I will check that out and see what is causing the problem!

I will try to implement that.

I have looked over the code and tested various amounts of data. I posted over 16000 characters in QUOTED text, with and without proper QUOTE tags. Everything worked as expected.

Could you do me a favor? Check your forums "Maximum Characters Per Post" setting. That may be what is causing this issue. The setting is in Message Posting and Editing Options.

The max characters setting is at 50,000.

This is the maximum amount that I can post in a single quote.

I can post that in a nested quote with more text in the outer quote, so I don't think it's the max characters per post that's gonked. If I turn off the mod, then the posts we're having trouble with go through fine.

Excellent. The next thing to check is the /includes/class_verifyquotes.php file. Specifically the Parse function. It should look like this:

PHP Code:

public function Parse($text) { 

    $text = preg_replace('#\[quote.*?\]#i','[quote]',$text);
    $text = preg_replace('#\[quote\]\[\/quote\]#i','',$text);
    $text = preg_replace('#\[noparse\].*?\[\/noparse\]#si','',$text);

    $text = $this->do_parse($text);
    return preg_match('/\[quote.*?\]|\[\/quote\]/si',$text);
  } 


if not, then you are still using the original buggy version.
