问题 I am trying to pull a random product thumbnail to display as an image on one of my pages. I can't seem to find a way that works, and have tried the solutions from this and this post. It would be beneficial to echo it out in a div as well. Here is what I am currently trying but I'm still unsure how to do this. functions.php: function get_random_thumbnails_for_reg(){ if(is_page(381)){ $args = array( 'tax_query' => array( array( 'taxonomy' => 'product_cat', 'field' => 'slug', 'terms' => 'allison

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I'm working with a dataset in R where the main area of interest is the date. (It has to do with army skirmishes and the date of the skirmish is recorded). I wanted to check if these were more likely to happen in a given season, or near a holiday, etc, so I want to be able to see

Category IDs for Microsoft Translator

由 ♀尐吖头ヾ 提交于 2020-01-07 06:24:19
问题 Are there other category IDs for Microsoft Translator besides tech, speech and generalnn? Where can I find them? 回答1: Valid category values are <blank> or "general", "tech", "speech", "generalnn" or a custom category identifier you copied from the Hub overview page. The result is not necessarily different for every language pair. 来源： https://stackoverflow.com/questions/44630374/category-ids-for-microsoft-translator

NSDate's initWithString: is returning nil

由 眉间皱痕 提交于 2020-01-07 04:32:14
问题 I'm using Stig Brautaset's JSON framework serialize some objects, including NSDates (which are not directly supported). I decided to use NSDate's description as the JSONFragment representation of a date (I don't care about the minor loss of precision incurred in doing so). To extend Stig Brautaset's JSON framework to include NSDates, I defined a category: @interface NSDate (NSDate_JSON) <JSONInitializer> -(NSString *) JSONFragment; @end To recreate an NSDate (and other classes) from JSON, I

Objective-C 接口编程

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1. @Protocal (协议) @protocal 是Objective-C 中普遍存在的接口定义方式，即在一个类中通过@protocal 中定义接口，在另外的类中实现该接口，这种定义方式夜晨为"delegate"模式。@protocal 声明了可以被其他任何类实现的方法，协议仅仅是定义一个接口，由其他类区负责实现。 "delegate"模式的使用共分为三个步骤： 1）接口声明:创建 一个protocal 文件T estDelegate @protocal TestDelegate<NSObject> @required -(void)doSomething; @end 2）接口回调： 定义一个类A，包含一个遵从此协议的属性CC，并定义一个方法用调用CC的方法，这样当实例化A的对象时，就可以通过delegate回调了。 @interface TestAppDelegate:NSObject { id <TestDelegate> delegate; } @property (retain) id delegate; @end @implementation TestAppDelegate -(void)doSomethingWithProtocal { [self.delegate doSomething]

由 余生颓废 提交于 2020-01-07 02:37:08
问题 In my sidebar I have two categories: 'Product' and 'News'. So I have created two category files category-product.php and category-news.php to display them in a different way. My question is: how can I create permalinks to display these separate category pages? The default permalink always displays the category.php file. Can anybody please provide some ideas? I'm very new to WordPress. 回答1: WordPress selects template based on request parse results, not only on permalink structure. When it
