This article will explain in detail how phpcms displays category names in front of the foreground article list. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1. Open phpcms\ caches\ caches_commons\ caches_data\ category_content_1.cache.php

Return array (1 = > array ('catid' = >' 1century, 'siteid' = >' 1', 'type' = >' 1', 'modelid' = >' 01', 'parentid' = >' 01', 'arrparentid' = >' 01', 'child' = >' 1Qing, 'arrchildid' = >' 1Jing 2, 3PM 5162cm, 'catname' = >' website introduction', 'style' = >', 'image' = >'' 'description' = >', 'parentdir' = >', 'catdir' = >' about', 'url' = >' / html/about/', 'items' = >' 0mm, 'hits' = >' 01', 'setting' = >' array (\ 'ishtml\' = >\'1\',\ 'template_list\' = >\ 'default\',\ 'page_template\' = >\ 'page\',\ 'meta_title\' = >\'\' \ 'meta_keywords\' = >\'\',\ 'meta_description\' = >\'\,\ 'category_ruleid\' = >\'1\',\ 'show_ruleid\' = >\'\',\ 'repeatchargedays\' = >\'1\',)', category_content_1.cache.php

As you can see, the details of all the column categories are cached here, including what we need.

'catname' = >' website introduction'

2. Open phpcms\ modules\ content\ classes\ content_tag.class.php

/ * list page label * @ param $data * / public function lists ($data) {$catid = intval ($data ['catid']); if (! $this- > set_modelid ($catid) return false; if (isset ($data [' where'])) {$sql = $data ['where'];} else {$thumb = intval ($data [' thumb'])? " AND thumb! =''":''; if ($this- > category [$catid] ['child']) {$catids_str = $this- > category [$catid] [' arrchildid']; $pos = strpos ($catids_str,',') + 1; $catids_str = substr ($catids_str, $pos); $sql =" status=99 AND catid IN ($catids_str) ". $thumb } else {$sql = "status=99 AND catid='$catid'". $thumb;}} $order = $data ['order']; $return = $this- > db- > select ($sql,' *', $data ['limit'], $order,'', 'id'); content_tag.class.php

3. Add the following code after the above code

$TYPES = getcache ('category_content_1','commons'); / / get category cache 2 foreach ($return as $key= > $v) {$return [$key] [typename] = $TYPES [$v [' catid']] ['catname']; / / add a category field to the array returned by the lists tag}

4. The foreground calls the method

{$v [typename]} this is the end of phpcms's method of displaying category names in front of the foreground article list. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
