• 3为多种自定义文字类型设置默认内容

在《WordPress TinyMCE 编辑器增强技巧大全》中，挖鱼源码网已经提到过为 WordPress TinyMCE编辑器设置默认文章内容的方法，今天主要是补充一下如果为自定义文章类型设置默认内容。什么是自定义文章类型？

为默认的文章类型（post）设置默认内容

回顾一下，WordPress 默认的文章类型为 post，我们可以在 functions.php 中添加下面的代码，就可以了：

1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8

add_filter<span style="color: #009900;">&#40;</span> <span style="color: #0000ff;">'default_content'</span><span style="color: #339933;">,</span> <span style="color: #0000ff;">'my_editor_content'</span> <span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #000000; font-weight: bold;">function</span> my_editor_content<span style="color: #009900;">&#40;</span> <span style="color: #000088;">$content</span> <span style="color: #009900;">&#41;</span> <span style="color: #009900;">&#123;</span> &nbsp; <span style="color: #000088;">$content</span> <span style="color: #339933;">=</span> <span style="color: #0000ff;">&quot;欢迎给 WordPress大学 投稿&quot;</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #b1b100;">return</span> <span style="color: #000088;">$content</span><span style="color: #339933;">;</span> <span style="color: #009900;">&#125;</span> 1 2 3 4 5 6 7 8 add_filter<span style="color: #009900;">&#40;</span> <span style="color: #0000ff;">'default_content'</span><span style="color: #339933;">,</span> <span style="color: #0000ff;">'my_editor_content'</span> <span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #000000; font-weight: bold;">function</span> my_editor_content<span style="color: #009900;">&#40;</span> <span style="color: #000088;">$content</span> <span style="color: #009900;">&#41;</span> <span style="color: #009900;">&#123;</span> &nbsp; <span style="color: #000088;">$content</span> <span style="color: #339933;">=</span> <span style="color: #0000ff;">&quot;欢迎给 WordPress大学 投稿&quot;</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #b1b100;">return</span> <span style="color: #000088;">$content</span><span style="color: #339933;">;</span> <span style="color: #009900;">&#125;</span>

add_filter( ‘default_content’, ‘my_editor_content’ ); function my_editor_content( $content ) { $content = "欢迎给 WordPress大学 投稿"; return $content;
}

为自定义文章类型（products）设置默认内容

那如果你有一种自定义文章类型为 product ，那你可以使用下面的代码，注意看第三行的 if 判断语句：

1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9

add_filter<span style="color: #009900;">&#40;</span> <span style="color: #0000ff;">'default_content'</span><span style="color: #339933;">,</span> <span style="color: #0000ff;">'default_products_content'</span> <span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #000000; font-weight: bold;">function</span> default_products_content<span style="color: #009900;">&#40;</span> <span style="color: #000088;">$content</span> <span style="color: #009900;">&#41;</span> <span style="color: #009900;">&#123;</span> &nbsp; <span style="color: #b1b100;">if</span><span style="color: #009900;">&#40;</span> <span style="color: #000088;">$_GET</span><span style="color: #009900;">&#91;</span><span style="color: #0000ff;">'post_type'</span><span style="color: #009900;">&#93;</span> <span style="color: #339933;">==</span> <span style="color: #0000ff;">'products'</span> <span style="color: #009900;">&#41;</span> <span style="color: #000088;">$content</span> <span style="color: #339933;">=</span> <span style="color: #0000ff;">&quot;预设文字内容&quot;</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #b1b100;">return</span> <span style="color: #000088;">$content</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #009900;">&#125;</span> 1 2 3 4 5 6 7 8 9 add_filter<span style="color: #009900;">&#40;</span> <span style="color: #0000ff;">'default_content'</span><span style="color: #339933;">,</span> <span style="color: #0000ff;">'default_products_content'</span> <span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #000000; font-weight: bold;">function</span> default_products_content<span style="color: #009900;">&#40;</span> <span style="color: #000088;">$content</span> <span style="color: #009900;">&#41;</span> <span style="color: #009900;">&#123;</span> &nbsp;     <span style="color: #b1b100;">if</span><span style="color: #009900;">&#40;</span> <span style="color: #000088;">$_GET</span><span style="color: #009900;">&#91;</span><span style="color: #0000ff;">'post_type'</span><span style="color: #009900;">&#93;</span> <span style="color: #339933;">==</span> <span style="color: #0000ff;">'products'</span> <span style="color: #009900;">&#41;</span> <span style="color: #000088;">$content</span> <span style="color: #339933;">=</span> <span style="color: #0000ff;">&quot;预设文字内容&quot;</span><span style="color: #339933;">;</span> &nbsp;     <span style="color: #b1b100;">return</span> <span style="color: #000088;">$content</span><span style="color: #339933;">;</span> &nbsp; <span style="color: #009900;">&#125;</span>

add_filter( ‘default_content’, ‘default_products_content’ ); function default_products_content( $content ) { if( $_GET[‘post_type’] == ‘products’ ) $content = "预设文字内容"; return $content; }

为多种自定义文字类型设置默认内容

上面举得例子是只给一种文章类型设置默认内容，如果你有很多种自定义文章类型，你可以使用下面的代码，更加简洁：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

add_filter<span style="color: #009900;">&#40;</span> <span style="color: #0000ff;">'default_content'</span><span style="color: #339933;">,</span> <span style="color: #0000ff;">'my_editor_content'</span><span style="color: #339933;">,</span> <span style="color: #cc66cc;">10</span><span style="color: #339933;">,</span> <span style="color: #cc66cc;">2</span> <span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span> &nbsp;

add_filter( ‘default_content’, ‘my_editor_content’, 10, 2 ); function my_editor_content( $content, $post ) { switch( $post->post_type ) {
case ‘sources’:
$content = ‘your content’;
break;
case ‘stories’:
$content = ‘your content’;
break;
case ‘pictures’:
$content = ‘your content’;
break;
default:
$content = ‘your default content’;
break;
} return $content;
}

上面的代码一共给几种文章类型（sources、stories、pictures 和 默认）设置默认内容，最后的“default:“表示除了上面的 3 种，其他的文章类型都是使用它的默认内容。
