好吧,我按照自己想要的方式工作。
我想用一個叫做'Accroche'的外場替換intro/full text。該字段的ID爲132(有用於瞭解將在下面的代碼中使用的ID)。
我們將編輯兩個文件:
/modules/mod_bt_contentslider/classes/content.php 和 /modules/mod_bt_contentslider/classes/k2.php
首先要做的就是讓extrafield從數據庫信息:
在/modules/mod_bt_contentslider/classes/content.php(圍繞線77)我加入並[b] a.extra_fields,[/ b]如下
$model->setState('list.select', 'a.urls, a.images, a.fulltext, a.id, a.title, a.alias, a.introtext, a.extra_fields, a.state, a.catid, a.created, a.created_by, a.created_by_alias,' . ' a.modified, a.modified_by,a.publish_up, a.publish_down, a.attribs, a.metadata, a.metakey, a.metadesc, a.access,' . ' a.hits, a.featured,' . ' LENGTH(a.fulltext) AS readmore');
保存文件&接近
現在讓我們去/modules/mod_bt_contentslider/classes/k2.php(約234線),
替換此原代碼
// cut introtext
if ($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
有了這個代碼,我已經評論過讓像我這樣的新手可以理解的東西;)
// 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,因爲我不想要它們,所以列出了介紹文本。如果你想同時使用introtext和extrafield,你可以修改它。
如果沒有上面給出的JSON提示,我從來沒有想過這個。感謝所有:)
希望這會有所幫助。
乾杯!
這是快速和完全準確的:-)謝謝! – 2013-04-24 03:45:05
