How does 'CONCATENATE_SCRIPTS' work on wp-config?
提问by eyyo
The text on my wordpress text editor is white on a white background so its invisible for most people..
我的 wordpress 文本编辑器上的文本是白色背景上的白色，因此对大多数人来说是不可见的。
I searched it and the solution I found was to add the following code to wp-config.php
我搜索了一下，找到的解决方案是将以下代码添加到 wp-config.php
define('CONCATENATE_SCRIPTS', false );
It worked fine but I couldn't find what it does or why it works.
它工作正常，但我找不到它的作用或它为什么起作用。
I only found a question that asks the same thing herebut it didn't get an answer.
我只在这里找到了一个提出同样问题的问题，但没有得到答案。
Could someone explain what the code above does and why it works?
有人能解释一下上面的代码是做什么的以及它为什么起作用吗？

First of all, nice question.
首先，好问题。
CONCATENATE_SCRIPTSis the constant that tells wordpress to, well.. concatenate all of the dependencies into one URL and load it together ( to save http requests I guess ).
CONCATENATE_SCRIPTS是告诉 wordpress 的常量，好吧.. 将所有依赖项连接到一个 URL 中并将其加载在一起（我猜是为了保存 http 请求）。
As far as I know, it applies only to the Admin area ( back end ). The result is a url like
据我所知，它仅适用于管理区域（后端）。结果是一个像
<script src="http://somewordpress.site/wp-admin/load-scripts.php?c=1&load=jquery-ui-core,jquery-ui-widget,jquery-ui-mouse,jquery-ui-sortable,hoverIntent,common,jquery-color,wp-ajax-response,wp-lists,jquery-ui-resizable,quicktags,jquery-query,admin-comments,postbox,dashboard,thickbox,plugin-install,media-upload&ver=e0f647a6df61adcc7200ce17a647db7f" type="text/javascript">
This is the normal default behavior, and if you have problems with it, it is probably because of some javascriptconflict in theme or plugin.
这是正常的默认行为，如果您遇到问题，可能是因为javascript主题或插件存在冲突。
Another possible ( albeit less frequent ) is a browser problem due to TinyMCE caching. clear browser cache. ( edit : was true to Sep.2015- not verified since but still worth trying )
另一种可能（虽然不太频繁）是由于 TinyMCE 缓存导致的浏览器问题。清除浏览器缓存。（编辑：对Sep.2015- 未验证但仍然值得尝试）
If you really want to see where it is defined or what is it doing you can look here.
如果你真的想看看它是在哪里定义的或者它在做什么，你可以看看这里。
Anyhow, by defining the constant as falseyou are practically forcing WordPress to load each script on the administration page individuallyrater than collectively.
So in that case - If one script fails to load and work correctly, the others can still continue to operate correctly.
无论如何，通过定义常量，false您实际上是在强制 WordPress 在管理页面上单独加载每个脚本而不是集体加载。所以在这种情况下 - 如果一个脚本无法加载并正常工作，其他脚本仍然可以继续正常运行。
This is a recommended setting for debuggingand local development.
However, in your case, it is a symptomof a problem, and not the problem itself. you should isolate the problem and fix it ( probably a plugin like said before )
这是debugging本地开发的推荐设置。但是，就您而言，这是问题的症状，而不是问题本身。您应该隔离问题并修复它（可能是之前所说的插件）

To expand upon Obmerk's answer, in my case setting CONCATENATE_SCRIPTSto false simply enabled me to see the individual failure in the browser console as it then showed the javascript for tinymce was not loading properly. Then looking at server logs showed that wp-tinymce.phpwas not executing properly. In the end, I needed to fix the permissions of {sitepath}/wp-includes/js/tinymce/wp-tinymce.phpso that the security settings of the server I was on would allow it to run.
为了扩展 Obmerk 的答案，在我的情况下，设置CONCATENATE_SCRIPTS为 false 只是让我能够在浏览器控制台中看到单个故障，因为它随后显示 tinymce 的 javascript 未正确加载。然后查看服务器日志显示wp-tinymce.php未正确执行。最后，我需要修复 的权限，{sitepath}/wp-includes/js/tinymce/wp-tinymce.php以便我所在服务器的安全设置允许它运行。
In my case the server did not allow it to be group-writable so a chmod 755took care of it. The actual solution will vary based on your server configuration.
在我的情况下，服务器不允许它是组可写的，所以chmod 755处理了它。实际解决方案将根据您的服务器配置而有所不同。
