The editor will share with you what the new function of WordPress2.9 is. I hope you will gain a lot after reading this article. Let's discuss it together.

1. Article thumbnail

One of the new features of WordPress 2.9 is that it provides thumbnails of articles that do not require custom fields, which will provide great convenience to users, but due to some compatibility restrictions, you have to modify the theme's function.php file to use this feature.

Add the following code to the function.php of the topic and you can use WordPress's article thumbnail feature.

If (function_exists ('add_theme_support')) {/ / check whether the WP version is version 2.9 or above add_theme_support (' post-thumbnails'); / / add article thumbnails} if the WP version meets the minimum requirements

Then add some code to the article list call to display the article thumbnail.

If ((function_exists ('has_post_thumbnail')) & & (has_post_thumbnail ()) {echo'. The_post_thumbnail (). If thumbnails of the article are supported and thumbnails exist in the article, thumbnails are displayed, otherwise the default image is displayed * / the key point to make the thumbnails of the article beautiful is the definition of the the_post_thumbnail () function, the following code provides a simple description. The_post_thumbnail (); / / with default parameters, please refer to the wp-includes/post-image-template.php file the_post_thumbnail ('thumbnail'); / / small thumbnail the_post_thumbnail (' medium'); / / medium thumbnail the_post_thumbnail ('large'); / / large thumbnail the_post_thumbnail (' medium', array ('class' = >' alignleft', 'alt' = >' alttext')) / / use medium thumbnail / / set the image resolution to 100x100 pixels, plus class= "alignleft" and description the_post_thumbnail (array (100100), array ('class' = >' alignleft', 'alt' = >' alttext')

2. Sidebar description function

The support of Widget is a successful attempt of WordPress, which gives users the flexibility to customize the content displayed in the sidebar and provides great convenience for the call of the plug-in. However, some themes support customizing multiple sidebars, which makes it difficult to install Widget correctly. The sidebar description is more likely to appear like bookmarking areas that support Widget, so users can see at a glance where the installed Widget will appear.

The way to add a sidebar description is to add the following code to the theme's function.php file.

Function register_theme_widget_areas () {/ / define the area register_sidebar where Widget can be installed (array (/ / define area parameter 'name' = >' Primary', / / sidebar name 'id' = >' primary', / / sidebar id' description' = > 'The primary widget area is used as top right sidebar.', / / sidebar description' before_widget' = >', 'after_widget' = >', 'before_title' = >'' 'after_title' = >' / * the above four lines are all styles that define the Widget Basically consistent with the old version * /)) } after reading this article, I believe you have a certain understanding of the new features of WordPress2.9, want to know more about it, welcome to follow the industry information channel, thank you for reading!
