phpcms v9增加类似于phpcms 2008中的关键词表,有需要学习的机友可参考一下,在model文件夹中增加一个keyword_ext_model.class.php,keyword_model实际是存在model文件夹中的,不知道为什么没有keyword这张表?
所以还是不要在这个基本上增加,也许将来这个model会用上,代码如下:
- <?php
- defined('IN_PHPCMS') or exit('No permission resources.');
- pc_base::load_sys_class('model', '', 0);
- class keyword_ext_model extends model {
- public $table_name = '';
- public function __construct() {
- $this->db_config = pc_base::load_config('database');
- $this->db_setting = 'default';
- $this->table_name = 'keyword_ext';
- parent::__construct();
- } //Vevb.com
- }
- ?>
然后创建一张表,代码如下:
- CREATE TABLE `t_v9_keyword_ext` (
- `tagid` smallint(5) unsigned NOT NULL AUTO_INCREMENT,
- `tag` char(50) NOT NULL,
- `style` char(5) NOT NULL,
- `usetimes` smallint(5) unsigned NOT NULL DEFAULT '0',
- `lastusetime` int(10) unsigned NOT NULL DEFAULT '0',
- `hits` mediumint(8) unsigned NOT NULL DEFAULT '0',
- `lasthittime` int(10) unsigned NOT NULL DEFAULT '0',
- `listorder` tinyint(3) unsigned NOT NULL DEFAULT '0',
- `modelid` smallint(6) DEFAULT '0',
- PRIMARY KEY (`tagid`),
- UNIQUE KEY `tag` (`tag`),
- KEY `usetimes` (`usetimes`,`listorder`),
- KEY `hits` (`hits`,`listorder`)
- ) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
最后一步在phpcms/modules/content/fields/keyword 中增加一个 input.inc.php,代码如下:
- function tags($field, $value)
- {
- if(!$value) return '';
- if(strpos($value, ','))
- {
- $s = ',';
- }
- else
- {
- $s = ',';
- }
- $keywords = isset($s) ? array_unique(array_filter(explode($s, $value))) : array($value);
- $keyword_db = pc_base::load_model('keyword_ext_model');
- foreach($keywords as $tag)
- {
- $tag = trim($tag);
- $keyword_db->delete(array("tag"=>$tag,"modelid"=>$this->modelid));
- $c=$this->db->count("keywords like '%".$tag."%'");
- $keyword_db->insert(array("modelid"=>$this->modelid,"tag"=>$tag,"usetimes"=>$c,"lastusetime"=>SYS_TIME),false,true);
- }
- return implode($s, $keywords);
- }
这样在文章增加关键词的时候,会自动增加到keyword_ext中一份,调用全站tags的时候直接调上这个表就行了.
