Now when open the post in my site i see permalink like :-

www.domain.com/tesla-will-reportedly-build-its-ev--batter

But i set the permalink structure is /%postname%/.

Why its not get all post title ?

Answer 1

 sanitize_title() is the function which is restricting the number of character for permalink.

  //  remove standard hook
 remove_filter( 'sanitize_title', 'sanitize_title_with_dashes' );

  // add custom hook 
 add_filter( 'sanitize_title', 'wptris_sanitize_title_with_dashes', 10, 3 );
function wptris_sanitize_title_with_dashes( $title, $raw_title = '', $context =   'display' ) {
$title = strip_tags($title);
// Preserve escaped octets.
$title = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '---$1---', $title);
// Remove percent signs that are not part of an octet.
$title = str_replace('%', '', $title);
// Restore octets.
$title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title);

if (seems_utf8($title)) {
    if (function_exists('mb_strtolower')) {
        $title = mb_strtolower($title, 'UTF-8');
    }
    $title = utf8_uri_encode($title, 1000); // <--- here is the trick!
}

$title = strtolower($title);
$title = preg_replace('/&.+?;/', '', $title); // kill entities
$title = str_replace('.', '-', $title);

if ( 'save' == $context ) {
    // Convert nbsp, ndash and mdash to hyphens
    $title = str_replace( array( '%c2%a0', '%e2%80%93', '%e2%80%94' ), '-', $title );

        // Strip these characters entirely
        $title = str_replace( array(
        // iexcl and iquest
        '%c2%a1', '%c2%bf',
        // angle quotes
        '%c2%ab', '%c2%bb', '%e2%80%b9', '%e2%80%ba',
        // curly quotes
        '%e2%80%98', '%e2%80%99', '%e2%80%9c', '%e2%80%9d',
        '%e2%80%9a', '%e2%80%9b', '%e2%80%9e', '%e2%80%9f',
        // copy, reg, deg, hellip and trade
        '%c2%a9', '%c2%ae', '%c2%b0', '%e2%80%a6', '%e2%84%a2',
        // grave accent, acute accent, macron, caron
        '%cc%80', '%cc%81', '%cc%84', '%cc%8c',
    ), '', $title );

    // Convert times to x
    $title = str_replace( '%c3%97', 'x', $title );
}

$title = preg_replace('/[^%a-z0-9 _-]/', '', $title);
$title = preg_replace('/\s+/', '-', $title);
$title = preg_replace('|-+|', '-', $title);
$title = trim($title, '-');

return $title;

}

// first of all lets remove standard hook
remove_filter( 'sanitize_title', 'sanitize_title_with_dashes' );

// add our custom hook 
add_filter( 'sanitize_title', 'wpse8170_sanitize_title_with_dashes', 10, 3 );
function wpse8170_sanitize_title_with_dashes( $title, $raw_title = '', $context = 'display' ) {
    $title = strip_tags($title);
    // Preserve escaped octets.
    $title = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '---$1---', $title);
    // Remove percent signs that are not part of an octet.
    $title = str_replace('%', '', $title);
    // Restore octets.
    $title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title);

    if (seems_utf8($title)) {
        if (function_exists('mb_strtolower')) {
            $title = mb_strtolower($title, 'UTF-8');
        }
        $title = utf8_uri_encode($title, 1000); // <--- here is the trick!
    }
