kik*_*ito 13 php string drupal slug
此上下文中的一个slug是一个字符串,可以安全地用作urls或css上的标识符.例如,如果您有此字符串:
I'd like to eat at McRunchies!
它的slu is将是:
i-d-like-to-eat-at-mcrunchies
我想知道是否有一种在Drupal上构建这样的字符串的标准方法(或drupal提供的php函数).更确切地说,在Drupal主题中.
上下文:我正在修改一个drupal主题,因此它生成的节点的html包括它们的分类术语作为包含div的css类.麻烦的是,其中一些术语的名称不是有效的css类名.我需要"迷恋"他们.
我读过有些人只是这样做:
str_replace(" ", "-", $term->name)
这对我来说真的不够.它不downcase代替大写字母,但更重要的是,不能取代非ASCII字符(如A或E)通过的ASCII码值.它也不会从开始和结束中删除"分隔符字符串".
有没有在Drupal 6(或PHP库)的功能,它提供了一种slugify一个字符串,并且可以在Drupal主题的template.php文件中使用吗？

您可以使用内置的Drupal函数来执行此操作.
$string = drupal_clean_css_identifier($string);
$slug = drupal_html_class($string);
函数将为你做到这一点.

我是一个快乐的Zen主题用户,因此我遇到了它附带的这个奇妙的功能:zen_id_safe http://api.lullabot.com/zen_id_safe
它不依赖于任何其他主题功能,因此您只需将其复制到您的模块或主题并使用它.它是一个非常小而简单的功能,所以我只是为了方便而粘贴在这里.
function zen_id_safe($string) {
// Replace with dashes anything that isn't A-Z, numbers, dashes, or underscores.
return strtolower(preg_replace('/[^a-zA-Z0-9-]+/', '-', $string));
}

谢谢你的回答.
我最终使用了slug这里解释的功能:http://www.drupalcoder.com/story/554-how-to-create-url-aliases-in-drupal-without-path-module(在文章的最后,你必须点击才能看到源代码).
这可以满足我的需求和更多功能,而无需包含外部模块等.
粘贴下面的代码以便日后参考:
/**
* Calculate a slug with a maximum length for a string.
*
* @param $string
* The string you want to calculate a slug for.
* @param $length
* The maximum length the slug can have.
* @return
* A string representing the slug
*/
function slug($string, $length = -1, $separator = '-') {
// transliterate
$string = transliterate($string);
// lowercase
$string = strtolower($string);
// replace non alphanumeric and non underscore charachters by separator
$string = preg_replace('/[^a-z0-9]/i', $separator, $string);
// replace multiple occurences of separator by one instance
$string = preg_replace('/'. preg_quote($separator) .'['. preg_quote($separator) .']*/', $separator, $string);
// cut off to maximum length
if ($length > -1 && strlen($string) > $length) {
$string = substr($string, 0, $length);
}
// remove separator from start and end of string
$string = preg_replace('/'. preg_quote($separator) .'$/', '', $string);
$string = preg_replace('/^'. preg_quote($separator) .'/', '', $string);
return $string;
}
/**
