好的,我让它按照我想要的方式工作。
我想用我称为 'Accroche' 的额外字段替换介绍/全文。这个额外字段的 ID 为 132(有助于了解将在下面的代码中使用的 ID)。
我们将编辑 2 个文件:
/modules/mod_bt_contentslider/classes/content.php 和 /modules/mod_bt_contentslider/classes/k2.php
首先要做的是从数据库中获取外场信息:
在 /modules/mod_bt_contentslider/classes/content.php (第 77 行附近)我添加 [b]a.extra_fields,[/b] 如下
$model->setState('list.select', 'a.urls, a.images, a.fulltext, a.id, a.title, a.alias, a.introtext, a.extra_fields, a.state, a.catid, a.created, a.created_by, a.created_by_alias,' . ' a.modified, a.modified_by,a.publish_up, a.publish_down, a.attribs, a.metadata, a.metakey, a.metadesc, a.access,' . ' a.hits, a.featured,' . ' LENGTH(a.fulltext) AS readmore');
保存文件并关闭
现在让我们进入 /modules/mod_bt_contentslider/classes/k2.php (大约第 234 行),
替换此原始代码
// cut introtext
if ($limitDescriptionBy == 'word') {
$item->description = self::substrword($item->introtext, $maxDesciption, $replacer, $isStrips, $stringtags);
$item->description = self::substring($item->introtext, $maxDesciption, $replacer, $isStrips, $stringtags);
}
$item->categoryLink = urldecode(JRoute::_(K2HelperRoute::getCategoryRoute($item->catid . ':' . urlencode($item->categoryalias))));
// get author name & link
使用我评论过的这段代码,让像我这样的菜鸟可以理解;)
// REPLACE intro/full text With extra-field info
$extras = json_decode($item->extra_fields); // JSON Array we'll call extras (note final 's' : not to confuse with below variable)
foreach ($extras as $key=>$extraField): //Get values from array
if($extraField->value != ''): //If not empty
if($extraField->id == '132'): // This is ID value for extrafield I want to show --- Search your K2 extrafield's id in Joomla backoffice ->K2 ->extrafields ---
if($extraField->value != ''): // If there's content in the extrafield of that ID
$extra = $extraField->value; //Give $extra that value so we can hand it down below
endif;
endif;
endif;
endforeach;
// cut introtext
if ($limitDescriptionBy == 'word') {
// $item->description = self::substrword($item->introtext, $maxDesciption, $replacer, $isStrips, $stringtags);
$item->description = self::substrword($extra, $maxDesciption, $replacer, $isStrips, $stringtags);
} else {
// $item->description = self::substring($item->introtext, $maxDesciption, $replacer, $isStrips, $stringtags);
$item->description = self::substring($extra, $maxDesciption, $replacer, $isStrips, $stringtags) ;
}
$item->categoryLink = urldecode(JRoute::_(K2HelperRoute::getCategoryRoute($item->catid . ':' . urlencode($item->categoryalias))));
// get author name & link
正如你所看到的,我已经注释掉了介绍文本,因为我不想要它们。如果你想要 introtext 和 extrafield,你可以修改它。
如果没有上面给出的 JSON 提示,我永远不会想到这一点。谢谢大家:)
希望这可以帮助。
干杯!
