[英]Conditional if a post in tt_news belongs to certain category
I made a custom marker for tt_news which shows the first image from the media field, OR the third if it belongs to certain category (lets say category with ID = 2). 我为tt_news创建了一个自定义标记,该标记显示了媒体字段中的第一张图像,如果它属于某个类别,则显示第三张图像(假设ID为2的类别)。 I dont know how to make that conditional.
我不知道该怎么做。 This is what I have so far:
这是我到目前为止的内容:
10 = IMAGE
10.file{
width = 550
height = 350
import = uploads/pics/
import{
field = image
listNum = 0
#If also belongs to the category "Startseite", the listNum should be 2
listNum.stdWrap.override = TEXT
listNum.stdWrap.override{
value = 0
if{
#??????
}
}
}
}
You need to write custom condition as described in doc in userFunc
section (bottom) 您需要按照
userFunc
部分(底部)中的文档所述编写自定义条件

News and categories are connected with MM relation so you just to check if MM table contains this pair... 新闻和类别与MM关系有关,因此您只需检查MM表是否包含此对...

: typo3conf/localconf.php
:
function user_newsInCategory($catUid) {
$ttNewsGet = (t3lib_div::_GP('tx_ttnews'));
$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery(
'uid_foreign',
'tt_news_cat_mm',
'uid_foreign = ' . $catUid . ' AND uid_local=' . intval($ttNewsGet['tt_news'])
);
return ($GLOBALS['TYPO3_DB']->sql_num_rows($res) > 0) ? true : false;
}
somwhere in TS after your 10 = IMAGE { ... }
block: 在您的
10 = IMAGE { ... }
块之后的TS中的某处:
[userFunc = user_newsInCategory(2)]
10.file.import.listNum = 2
[end]
edit: 编辑:
As you can see in the sample it works only if news is displayed (ie. if param &tx_ttnews[tt_news] exists in URL) 如您在示例中所看到的,它仅在显示新闻时才起作用(即,URL中存在参数&tx_ttnews [tt_news])
To check similar check per each list item you need to use custom marker via hook (as described in tt_news manual ) by using extraItemMarkerProcessor - then you can use similar condition per each $row to display different images. 要检查每需要通过钩使用自定义标记(如所描述的每个列表项目类似的检查tt_news手册中通过使用extraItemMarkerProcessor) -然后就可以使用同样的条件每每$行来显示不同的图像。
