You run the function when you're looping through the results - not in the query itself.

I looked in /includes/functions.php and found the following lines of code:

PHP Code:
// #############################################################################
/**
* Trims a string to the specified length while keeping whole words
*
* @param    string    String to be trimmed
* @param    integer    Number of characters to aim for in the trimmed string
* @param  boolean Append "..." to shortened text
*
* @return    string
*/
function fetch_trimmed_title($title, $chars = -1, $append = true)
{
    global $vbulletin;

    if ($chars == -1)
    {
        $chars = $vbulletin->options['lastthreadchars'];
    }

    if ($chars)
    {
        // limit to 10 lines (\n{240}1234567890 does weird things to the thread preview)
        $titlearr = preg_split('#(\r\n|\n|\r)#', $title);
        $title = '';
        $i = 0;
        foreach ($titlearr AS $key)
        {
            $title .= "$key \n";
            $i++;
            if ($i >= 10)
            {
                break;
            }
        }
        $title = trim($title);
        unset($titlearr);

        if (vbstrlen($title) > $chars)
        {
            $title = vbchop($title, $chars);
            if (($pos = strrpos($title, ' ')) !== false)
            {
                $title = substr($title, 0, $pos);
            }
            if ($append)
            {
                $title .= '...';
            }
        }

        //$title = fetch_soft_break_string($title);
    }

    return $title;
}

// 

Now if I use the above code as it is in my page it doesn't work, ie. no trimming of the thread-titles. I've tried changing the value of $chars from -1 to other values like 45 but that doesn't work either. Do I need to change anything else for this code to correctly trim the thread-titles?

Can you please give an example of the code I need to use?

fetch_trimmed_title() is a function, you use it like any other function such as substr() or rand() or mysql_query() or something. It is just a user defined function, nothing special.
Quote:
fetch_trimmed_title (line 641)
Trims a string to the specified length while keeping whole words
fetch_trimmed_title (string $title, [integer $chars = -1], [boolean $append = true])
  • string $title: String to be trimmed
  • integer $chars: Number of characters to aim for in the trimmed string
  • boolean $append: Append "..." to shortened text
That tells you what variables you put into the function. (It is the same as when http://php.net/substr lists what parameters are for the substr() function)

what does the -1 in ' integer $chars = -1 ' mean?

Can someone refer me to a website / tutorial which would answer these kind of questions?

Look in the function's code - you even posted it. It's one of the first lines of the actual function.

I know it's the number of characters to aim for in the trimmed string, but I was asking specifically about the negative value, ie. why the number of characters is a negative value ( -1 ).

Dismounted meant you should read the PHP code, for the function, you yourself have already posted...

https://vborg.vbsupport.ru/showpost....8&postcount=12

(Read it line by line if you need to :p)

sparklywater 09-06-2008 08:00 AM
that doesn't answer my question, and you're not helping.

Opserty 09-06-2008 08:20 AM
Go to the 15th line of the PHP code you posted... I don't need to help you. The answer is staring you in the face. ;)

If, after you've read the 15th line (and the few lines after it) and I mean after! (No cheating :p) You still don't understand, post the 15th line and 3 lines underneath it.
