由网站背景显示出错到标签云wp_tag_cloud源文件

今天下午6点左右，不知道我到底设置了什么，导致WP在Firefox下面的背景显示出错，找了很多方法，最终没有中我意的，只好恢复一下以前的备份，后来发表文章的时候发现，用系统自带的标签系统添加标签不行，用simple tags 的标签添加还不行，而且发表文章的时候总是提示发表不成功请重试，这让我很恼火，而且编辑文章的时候WP很慢很慢，这让我对simple tags 产生了疑问，我用这个插件很简单的理由，其实就只是想调整一下默认标签云的样式，大家都知道默认的标签云比较难看，特别是字体变大后就更不好看了，我就只想调整下字体就行了，可是按照网上说的修改模板里面sidebar.php里面的wp_tag_cloud函数里面的默认值不起作用。。。
这样我才安装了simple tags。

既然不好用，找了半天也没找到问题所在，那就只有删掉了。可删掉后默认标签云真的不好看啊。。。无奈之余我又找wp_tag_cloud相关文章，极大部分的文章都是让修改sidebar.php里面的wp_tag_cloud函数里面的默认值，对我行不通，只能另找方法，后来到了WP的官网，搜索wp_tag_cloud  后来发现了对这个函数的解释。。。其实解释我都知道的，正当我想关掉这个网页的时候发现了这个东西：

Source File

wp_tag_cloud() is located in wp-includes/category-template.php.

这是标签云函数的源文件啊，这下不愁了~~ 马上找到他，修改smallest 和largest的值，成功！！呵呵。

下面是默认的category-template

function wp_tag_cloud( $args = ” ) {
 $defaults = array(
  ‘smallest’ => 8, ‘largest’ => 22, ‘unit’ => ‘pt‘, ‘number’ => 45,
  ‘format’ => ‘flat’, ‘orderby’ => ‘name’, ‘order’ => ‘ASC’,
  ‘exclude’ => ”, ‘include’ => ”, ‘link’ => ‘view’, ‘taxonomy’ => ‘post_tag’, ‘echo’ => true
 );

这是我修改后的

function wp_tag_cloud( $args = ” ) {
 $defaults = array(
  ‘smallest’ => 13, ‘largest’ => 18, ‘unit’ => ‘px‘, ‘number’ => 45,
  ‘format’ => ‘flat’, ‘orderby’ => ‘name’, ‘order’ => ‘ASC’,
  ‘exclude’ => ”, ‘include’ => ”, ‘link’ => ‘view’, ‘taxonomy’ => ‘post_tag’, ‘echo’ => true
 );

我仅仅就修改了字体的大小还有单位。

下面是网上的中文解释

标准语法：

<?php wp_tag_cloud(”); ?>

带参数：

<?php wp_tag_cloud(’number=30&smallest=12&largest=12&unit=px’); ?>

详细参数及说明：

• smallest：标签文字最小字号，默认为8pt；
• largest：标签文字最大字号，默认为22pt；
• unit：标签文字字号的单位，默认为pt，可以为px、em、pt、百分比等；
• number：调用的标签数量，默认为45个，设置为“0”则调用所有标签；
• format：调用标签的格式，可选“flat”、“list”和“array”，默认为“flat”平铺，“list”为列表方式；
• orderby：调用标签的排序，默认为“name”按名称排序，“count”则按关联的文章数量排列；
• order：排序方式，默认为“ASC”按正序，“DESC”按倒序，“RAND”按任意顺序。
• exclude：排除部分标签，输入标签ID，并以逗号分隔，如“exclude=1,3,5,7”不显示ID为1、3、5、7的标签；
• include：包含标签，与exclude用法一样，作用相反，如“include=2,4,6,8”则只显示ID为2、4、6、8的标签。

另外再附上官网的原版英文解释

 下面是修改后的字体，只是没有原来那种两种字体大小差别很大而已。
