WordPress开发中短代码的实现及相关函数使用技巧

function myName() {//短代码要处理的函数
return "My name's XiangZi !";
}
//挂载短代码
//xz为短代码名称 
//即你在编辑文章时输入[xz]就会执行 myName 函数
add_shortcode('xz', 'myName');

My name's XiangZi !

function myName($array,$content) {
var_dump($array);
var_dump($content);
}
 
add_shortcode('xz', 'myName');

[xz a="1" b="2" c="3"]这里是三个参数哦[/xz]

//$array 是一个数组，
//大体结构如下
$array = array('a'=>'1','b'=>'2','c'=>'3');
//$content 是一个字符串
$content = '这里是三个参数哦';

shortcode_atts(array(
"url" => 'http://PangBu.Com'
), $url)

  Combine user attributes with known attributes and fill in defaults when needed.
 
  The pairs should be considered to be all of the attributes which are
  supported by the caller and given as a list. The returned attributes will
  only contain the attributes in the $pairs list.
 
  If the $atts list has unsupported attributes, then they will be ignored and
  removed from the final returned list.
 
  @since 2.5
 
  @param array $pairs Entire list of supported attributes and their defaults.
  @param array $atts User defined attributes in shortcode tag.
  @return array Combined and filtered attribute list.

function shortcode_atts($pairs, $atts) {
 $atts = (array)$atts;
 $out = array();
 foreach($pairs as $name => $default) {
 if ( array_key_exists($name, $atts) )
  $out[$name] = $atts[$name];
 else
  $out[$name] = $default;
 }
 return $out;
