Here, on bp.org, there’s a message that says:

`To display code, put it between backticks.`

On my BP install, it doesn’t exist. Backticks are ignored and I can’t paste in code (HTML tags are filtered and not escaped).

Where should I look to enable this?

[@boonebgorges Keymaster 14 years, 2 months ago]

Here’s the code that does it on buddypress.org. It’s basically repurposed from bbPress.

I had to replace the actual backtick with the phrase `[backtick]` so that it would render properly on this forum. Make sure to correct that in your version.

`// Borrowed from bbPress
function bporg_encodeit( $matches ) {
$text = trim($matches[2]);
$text = htmlspecialchars($text, ENT_QUOTES);
$text = str_replace(array(“rn”, “r”), “n”, $text);
$text = preg_replace(“|nnn+|”, “nn”, $text);
$text = str_replace(‘&’, ‘&’, $text);
$text = str_replace(‘<', '<', $text);
$text = str_replace(‘>’, ‘>’, $text);
$text = “$text“;
if ( “[backtick]” != $matches[1] )
$text = “

$text

“;
return $text;
}

// Borrowed from bbPress
function bporg_decodeit( $matches ) {
$text = $matches[2];
$trans_table = array_flip(get_html_translation_table(HTML_ENTITIES));
$text = strtr($text, $trans_table);
$text = str_replace(‘
‘, ”, $text);
$text = str_replace(‘

‘, ”, $text);
$text = str_replace(‘

‘, ”, $text);
$text = str_replace(array(‘&’,’&’), ‘&’, $text);
$text = str_replace(”’, “‘”, $text);
if ( ‘

' == $matches[1] )

$text = "n$textn";

return "`$text`";

}



// Borrowed from bbPress. Makes code in backticks work, both in forum posts and in activity updates.

function bporg_code_trick( $text ) {

$text = str_replace(array("rn", "r"), "n", $text);

$text = preg_replace_callback("|(`)(.*?)`|", 'bporg_encodeit', $text);

$text = preg_replace_callback("!(^|n)`(.*?)`!s", 'bporg_encodeit', $text);

return $text;

}

add_filter( 'bp_get_the_topic_post_content', 'bporg_code_trick', 1 );

add_filter( 'bp_get_activity_content_body', 'bporg_code_trick', 1 );`

Hi @boonebgorges

i think there is a error in function bporg_decodeit

`$text = str_replace(”’, “‘”, $text);`

i also tried this code but it doen’t work for me. I added it in bp-forums-filter.php. Probably the wrong place.

[@chouf1 Participant 14 years, 1 month ago]

No solution ?

[@boonebgorges Keymaster 14 years, 1 month ago]

It looks like some of the escaped characters got stripped. Here’s what it’s supposed to look like: http://pastebin.com/Mvyc8TYx

[@chouf1 Participant 14 years, 1 month ago]

Sorry, it’s not ok !
view here, i tried to insert with backtick and [code, but pre tags are missing in the example….

[@boonebgorges Keymaster 14 years, 1 month ago]

The code in the pastebin is exactly what’s running on bp.org, so it definitely works. If there’s a problem, it might be a theme-related conflict.

Make sure that you’re only using backticks, not [ code ]

[@chouf1 Participant 14 years, 1 month ago]

i give a try here, using backticks
`
function bporg_decodeit( $matches ) {
$text = $matches[2];
$trans_table = array_flip(get_html_translation_table(HTML_ENTITIES));
$text = strtr($text, $trans_table);
$text = str_replace(‘
‘, ”, $text);
$text = str_replace(‘

‘, ”, $text);
$text = str_replace(‘

‘, ”, $text);
$text = str_replace(array(‘&’,’&’), ‘&’, $text);
$text = str_replace(”’, “‘”, $text);
if ( ‘

' == $matches[1] )

$text = "n$textn";

return "`$text`";

}

`

on my forum it is showing this

[@chouf1 Participant 14 years, 1 month ago]

I’m using a standard BP theme as child theme , and only for translation purpose.
As you can compare with what is on pastebin, some code is wrong, also here on bp.org

the return contains $text between backstick, but they are converted to < code >

[@chouf1 Participant 14 years, 1 month ago]

it seems that i have a character conflict with backstick and UTF8/Mysql input/output
& # 96; ( the html entity) is readed as a “real” backtick in the browser,
but injecting a “real” backtick like a php code copy/paste action, is not rendered correctly.

[@boonebgorges Keymaster 14 years, 1 month ago]

Yeah, it’s not totally reliable with all different kinds of characters. I took the code directly from bbPress without any real modification. One of these days I will take a closer look to see if I can improve the way it escapes special characters.

[@chouf1 Participant 14 years, 1 month ago]

I got it at least…

What i need is the possibility to copy/paste some code in my forum posts.
The code on the pastebin is globally correct, but as boone says, “it’s not totally reliable”.

The first thing, i you want to use it, is to copy paste the given code into your child theme function.php file.
Then you add a filter to deactivate the (damned) default typographical double cote wp filter

remove_filter( ‘bp_get_the_topic_post_content’, ‘wptexturize’ );

here the code you find on pastebin

in the function bporg_decodeit, retrieve <code> in the if statement
`if ( ‘

' == $matches[1] )`

Should be

`if ( '
' == $matches[1] )`



In the function bporg_code_trick, there are 4 backticks, we have to change this a little



In the first callback, replace the FIRST backstick by & # 96 ; (without space)

In the second callback, replace the SECOND backstick by & # 96 ; (without space)



That's it ! Now you can copy most of php code with backstick and the right double cotes.
