php - yoast - Generar URLs amigables para SEO(slugs)

slug jquery

Question

Definición

De Wikipedia :

Un slug es la parte de una URL que identifica una página que utiliza palabras clave legibles.

Para hacer que la URL sea más fácil para los usuarios, los caracteres especiales a menudo también se eliminan o se reemplazan. Por ejemplo, los caracteres acentuados generalmente son reemplazados por letras del alfabeto inglés; Los signos de puntuación generalmente se eliminan; y los espacios (que deben codificarse como% 20 o +) se reemplazan por guiones (-) o guiones bajos (_), que son más agradables estéticamente.

Contexto

Desarrollé un sitio web para compartir fotos en el que los usuarios pueden subir, compartir y ver fotos.

Todas las páginas se generan automáticamente sin mi control sobre el título. Debido a que el título de una foto o el nombre de un usuario pueden contener caracteres o espacios acentuados, necesitaba una función para crear automáticamente las babosas y mantener las URL legibles.

Creé la siguiente función que reemplaza los caracteres acentuados (èêëçî), elimina la puntuación y los caracteres incorrectos (# @ & ~ ^!) Y transforma los espacios en guiones.

Preguntas

• ¿Qué opinas sobre esta función?
• ¿Conoces alguna otra función para crear babosas?

Algunas personas se han vinculado a "php-slugs" en google.com, pero parece que su página está un poco arruinada ahora, así que aquí está si alguien la necesita:

function my_str_split($string)

    $slen=strlen($string);
    for($i=0; $i<$slen; $i++)

    return $sArray;

Encontré esto en la red, hace exactamente lo que quiere, pero mantiene el caso.

function sluggable($p) {
    $ts = array("/[À-Å]/","/Æ/","/Ç/","/[È-Ë]/","/[Ì-Ï]/","/Ð/","/Ñ/","/[Ò-ÖØ]/","/×/","/[Ù-Ü]/","/[Ý-ß]/","/[à-å]/","/æ/","/ç/","/[è-ë]/","/[ì-ï]/","/ð/","/ñ/","/[ò-öø]/","/÷/","/[ù-ü]/","/[ý-ÿ]/");
    $tn = array("A","AE","C","E","I","D","N","O","X","U","Y","a","ae","c","e","i","d","n","o","x","u","y");
    return preg_replace($ts,$tn, $p);
}

Este grupo de funciones convierte los caracteres especiales para incluir solo az , 0-9 y - . También hace un par de cosas adicionales como convertir ampersands ( & ) a la palabra and .

 foreach($space_chars as $char){

Answer 4

Esto realmente funciona bien. Devuelve la barra de url limpia correcta.

$string = ''(1234) S*m@#ith S)&+*t `E}{xam)ple?>land   - - 1!_2)#3)(*4""5'';

// remove all non alphanumeric characters except spaces
$clean =  preg_replace(''/[^a-zA-Z0-9/s]/'', '''', strtolower($string)); 

// replace one or multiple spaces into single dash (-)
$clean =  preg_replace(''!/s+!'', ''-'', $clean); 

echo $clean; // 1234-smith-st-exampleland-12345

Answer 5

Me gusta el código php-slugs en la solución de Google Code. Pero si quieres uno más simple que funcione con UTF-8:

function format_uri( $string, $separator = ''-'' )
{
    $accents_regex = ''~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i'';
    $special_cases = array( ''&'' => ''and'', "''" => '''');
    $string = mb_strtolower( trim( $string ), ''UTF-8'' );
    $string = str_replace( array_keys($special_cases), array_values( $special_cases), $string );
    $string = preg_replace( $accents_regex, ''$1'', htmlentities( $string, ENT_QUOTES, ''UTF-8'' ) );
    $string = preg_replace("/[^a-z0-9]/u", "$separator", $string);
    $string = preg_replace("/[$separator]+/u", "$separator", $string);
    return $string;
}

Asi que

echo format_uri("#@&~^!âèêëçî");

salidas

-and-aeeeci

Por favor, comenta si encuentras algunos errores.

Answer 8

function remove_accents($string)
{
    $a = ''ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûýýþÿŔŕ'';
    $b = ''aaaaaaaceeeeiiiidnoooooouuuuybsaaaaaaaceeeeiiiidnoooooouuuyybyRr'';
    $string = strtr(utf8_decode($string), utf8_decode($a), $b);
    return utf8_encode($string);
}

function format_slug($title)
{
    $title = remove_accents($title);
    $title = trim(strtolower($title));
    $title = preg_replace(''#[^a-z0-9//-/]#i'', ''_'', $title);
    return trim(preg_replace(''/-+/'', ''-'', $title), ''-/'');
}

utilizar: echo format_slug ($ var);

function seourl($phrase, $maxLength = 100000000000000) {
        $result = strtolower($phrase);

        $result = preg_replace("~[^A-Za-z0-9-/s]~", "", $result);
        $result = trim(preg_replace("~[/s-]+~", " ", $result));
        $result = trim(substr($result, 0, $maxLength));
        $result = preg_replace("~/s~", "-", $result);

        return $result;
    }

Answer 10

    setlocale(LC_ALL, ''en_US.UTF8'');

        function slugify($text)
        {
          // replace non letter or digits by -
          $text = preg_replace(''~[^//pL/d]+~u'', ''-'', $text);

          // trim
          $text = trim($text, ''-'');

          // transliterate
          $text = iconv(''utf-8'', ''us-ascii//TRANSLIT'', $text);

          // lowercase
          $text = strtolower($text);

          // remove unwanted characters
          $text = preg_replace(''~[^-/w]+~'', '''', $text);

          if (empty($text))
          {
            return ''n-a'';
          }

          return $text;
        }


$slug = slugify($var);
