892天前一：在配置中载入标签库 |
'APP_AUTOLOAD_PATH' => '@.TagLib', |
'TAGLIB_BUILD_IN' => 'Cx,Hd', //Cx是tp里的核心标签 Hd是自己写的自定义标签名 |
二：写一个自定义标签类 |
<?php |
import('TagLib'); |
/* |
*自定义标签库 |
*/ |
Class TagLibHd extends TagLib{ |
Protected $tags =array( |
'nav' => array('attr' => 'limit,order','close' => 1), //定义属性 close=>1闭合标签 |
'hot' => array('attr' => 'limit','close' => 1), |
'new' => array('attr' => 'limit','close' => 1) |
); |
Public function _nav ($attr,$content) { |
$attr = $this->parseXMLAttr($attr); |
$str = <<<str |
<?php |
\$_nav_cate = M('cate')->order("{$attr['order']}")->select(); |
import('Class.Category',APP_PATH); |
\$_nav_cate = Category::unlimitedForLayer(\$_nav_cate); |
foreach (\$_nav_cate as \$_nav_cate_v) : |
extract(\$_nav_cate_v); |
\$url = U('/c_'.$id); |
?> |
str; |
$str .= $content; |
$str .= '<?php endforeach;?>'; |
return $str; |
} |
Public function _hot ($attr,$content) { |
$attr = $this->parseXMLAttr($attr); |
$limit = $attr['limit']; |
$str = <<<str |
<?php |
\$field = array('id','title','hits'); |
\$_hot_blog = M('blog')->field(\$field)->limit({$limit})->order('hits DESC')->select(); |
foreach (\$_hot_blog as \$_hot_value) : |
extract(\$_hot_value); |
\$url = U('/'.\$id); |
?> |
str; |
$str .= $content; |
$str .= '<?php endforeach;?>'; |
return $str; |
} |
Public function _new ($attr,$content) { |
$attr = $this->parseXMLAttr($attr); |
$limit = $attr['limit']; |
$str = <<<str |
<?php |
\$field = array('id','title','time','hits'); |
\$_hot_blog = M('blog')->field(\$field)->limit({$limit})->order('time DESC')->select(); |
foreach (\$_hot_blog as \$_hot_value) : |
extract(\$_hot_value); |
\$url = U('/'.\$id); |
?> |
str; |
$str .= $content; |
$str .= '<?php endforeach;?>'; |
return $str; |
} |
} |
?> |
三：在模板中使用标签 |
