Troncamento dei campi personalizzati

Consulta la discussioneper Tassonomiabreve descrizione per unmodomiglioreper accorciare una stringa. Non sono a conoscenza di unafunzione WP che sta ottenendoiltroncamento corretto.

Eccoilmio codicebasato sulla discussione collegata:

 /**
 * Accorcia una stringa con codifica UTF-8 senzainterrompere leparole.
 *
 * @param string $ string stringa da accorciare
 * @paramint $max_chars lunghezzamassimain caratteri
 * @param string $ append sostituzioneperparoletroncate.
 * @return stringa
 */
funzione utf8_truncate ($ string,$max_chars=200,$ append="\ xC2 \ xA0…")
{
    $ stringa=strip_tags ($ stringa);
    $ string=html_entity_decode ($ string,ENT_QUOTES,'utf-8');
//\ xC2 \ xA0 è lo spaziono-break
    $ stringa=trim ($ stringa,"\n \ r \t .-; -,- \ xC2 \ xA0");
    $ lunghezza=strlen (utf8_decode ($ stringa));

//Niente dafare.
 if ($ length & lt; $max_chars)
    {
        restituire $ stringa;
    }

//mb_substr () èin/wp-includes/compat.php come riserva se
//latua attualeinstallazione di PHPnon ce l'ha.
    $ stringa=mb_substr ($ stringa,0,$max_chars,'utf-8');

//Nessuno spaziobianco. Unaparola lunga otesto cinese/coreano/giapponese.
 if (FALSO===strpos ($ stringa,''))
    {
        restituire $ stringa. $ append;
    }

//Evita leinterruzioni all'interno delleparole. Trova l'ultimo spaziobianco.
 if (extension_loaded ('mbstring'))
    {
        $pos=mb_strrpos ($ stringa,'','utf-8');
        $ short=mb_substr ($ stringa,0,$pos,'utf-8');
    }
    altro
    {
//Soluzione. Puòessere lento su stringhe lunghe.
        $parole=esplode ('',$ stringa);
//Lascia l'ultimaparola.
        array_pop ($parole);
        $ short=implode ('',$parole);
    }

    return $ short. $ append;
}
 

<"Test

 print utf8_truncate ('ööööö ööööö',10);
//stampa "ööööö…"
 

Aggiungi lafunzione altuo functions.php e cambiailtuo codicein:

 echo "& lt;p >" . utf8_truncate ($ desc). "& lt;/p >";
 

Puoi anche usarloper abbreviare untitolo:

 echo "& lt; h1 >" . utf8_truncate (get_the_title ()). "& lt;/h1 >";
 

See the discussion for Taxonomy Short Description for a better way to shorten a string. I’m not aware of a WP function that is getting truncation right.

Here is my code based on the linked discussion:

/**
 * Shortens an UTF-8 encoded string without breaking words.
 *
 * @param  string $string     string to shorten
 * @param  int    $max_chars  maximal length in characters
 * @param  string $append     replacement for truncated words.
 * @return string
 */
function utf8_truncate( $string, $max_chars = 200, $append = "\xC2\xA0…" )
{
    $string = strip_tags( $string );
    $string = html_entity_decode( $string, ENT_QUOTES, 'utf-8' );
    // \xC2\xA0 is the no-break space
    $string = trim( $string, "\n\r\t .-;–,—\xC2\xA0" );
    $length = strlen( utf8_decode( $string ) );

    // Nothing to do.
    if ( $length < $max_chars )
    {
        return $string;
    }

    // mb_substr() is in /wp-includes/compat.php as a fallback if
    // your the current PHP installation doesn’t have it.
    $string = mb_substr( $string, 0, $max_chars, 'utf-8' );

    // No white space. One long word or chinese/korean/japanese text.
    if ( FALSE === strpos( $string, ' ' ) )
    {
        return $string . $append;
    }

    // Avoid breaks within words. Find the last white space.
    if ( extension_loaded( 'mbstring' ) )
    {
        $pos   = mb_strrpos( $string, ' ', 'utf-8' );
        $short = mb_substr( $string, 0, $pos, 'utf-8' );
    }
    else
    {
        // Workaround. May be slow on long strings.
        $words = explode( ' ', $string );
        // Drop the last word.
        array_pop( $words );
        $short = implode( ' ', $words );
    }

    return $short . $append;
}

Test

print utf8_truncate( 'ööööö ööööö' , 10 );
// prints 'ööööö …'

Add the function to your functions.php and change your code to:

echo '<p>' . utf8_truncate( $desc ) . '</p>';

You can also use it shorten a title:

echo '<h1>' . utf8_truncate( get_the_title() ) . '</h1>';
