From Textpattern CMS User Documentation
The Advanced Preferences is where you enhance your site beyond just what is essential for basic function; for example, folder locations, custom fields, and the specifics on your publishing needs, just to name a few. All of the Advanced Preferences features are discussed on this page. (Edit: Updated to 4.2.0, but needs screenshots.)
As of Textpattern verson 4.2.0, the Advanced Preferences view is composed of six different regions. At the bottom of the view is a Save button, which should be clicked after any changes to any region are made.
The Admin section is composed of ten controls detailed in the following sections.
The root-relative URI (without opening or closing slashes) of the directory (folder) that holds images uploaded through the Images panel. By default this is "images", and you only need to change this if you have renamed and/or moved this directory.
File directory path
The full path (file path, not URI) to the directory (folder) for files uploaded via the Files panel. By default it is named "files" and is in the root directory of the website. As with the Image directory, you only need to change this if you have renamed and/or moved this directory.
Maximum file size of uploads (in bytes)
Maximim size for file uploads via the Files panel. Note that this value is also limited by the configuration of PHP on your Web server; if Textpattern detects that your PHP configuration only allows smaller downloads it will automatically correct this value downwards. If you want to allow larger file uploads via upload from the browser you have to talk with your host. (The relevant values in php.ini are
Temporary directory path
Full path (file path, not URI) for this directory, which is needed by Textpattern during uploads. By default it is named "tmp" and is at the root level of the installation. You should not need to change this.
Plugin cache directory path
Leave this empty unless you are using a plugin that requires it, or you are a plugin developer and want to test uncompiled plugins. No such directory is included by default.
SMTP envelope sender address
This preference should be left blank unless you experience problems with sending email in Textpattern (i.e., no email is sent at all). Should that problem arise, you can enter any valid email address here, although preferably one that has the same domain name as the website where you've installed Textpattern (i.e. if your website is example.com, you might use email@example.com).
Use ISO-8859-1 encoding in e-mails sent (default is UTF-8)?
For whatever reason (can someone give one?) you might want to use ISO-8859-1 character encoding for emails, but the more internationally friendly UTF-8 unicode is set by default, so why change?
Enable XML-RPC server
XML-RPC is an integral part of Textpattern, but disabled by default. To use XML-RPC for desktop publishing (publishing to your Textpattern site remotely), switch the server on by setting this to "Yes".
Default admin tab
Set this to the panel you want to appear when you log in.
Set the theme (appearance) of the admin panels. As of Textpattern 4.5, three themes are offered. "Classic" is the original theme with two rows of tabs. "Remora" is the updated Classic theme with a single row of tabs with drop-down menus. "Hive" is a modern, responsive theme and the basis of our future UI direction.
Require user's name?
If set to "Yes", people that want to comment on your blog will have to enter a name in the comment-form. They will receive an error message otherwise.
Require user's email address?
If set to "Yes", people that want to comment on your blog, will have to enter an email address in the comment-form. They will receive an error message otherwise.
Never display email address?
This setting controls whether the email address of a commenter should be shown publicly.
Apply rel="nofollow" to comments?
This will add an additional attribute to the links made in comments. It is intended to be a measure that takes away the incentive for comment-spammers and was initiated by a range of search engines and software-writers. You can find out more about it by reading Google's announcement.
Disallow user images?
With this option set to "Yes", images included in comments will be stripped out.
Allow more Textile markup in comments?
When set to "Yes", comments may contain Textile elements which would otherwise be treated as plain text:
- ordered and unordered lists
- foot notes
- extended block syntax (bc.., bq.., etc.)
For security reasons, raw HTML is transformed into regular text.
Spam blacklists (comma-separated)
The blacklist providers entered here, will be contacted when a comment is posted to your blog and the IP of the comment poster will be checked. If the IP is listed, it means there have been spamming complaints made about this IP in the past and a comment will be rejected.
You can enter a list of domain names that should be seperated by commas. Potential blacklists can be found at dmoz, but be aware that it is your responsibility to make sure you can trust those blacklist-providers before you add any.
New comment means site updated?
The database keeps track of when the last change to your site has happened. When this setting is set to "Yes", a new comment will also update this value. This value is used for example for the "Send Last-Modified header" functionality.
This region is where ten (10) custom fields can be defined. New installations of Textpattern define two custom fields for demonstration purposes: custom1 and custom2. When custom fields have names such as these, they automatically appear under the Advanced Options section of the Write panel so you can make use of them, as needed, in context of a given article.
Important notes on creating custom field names:
Custom field names may include letters (uppercase or lowercase), numbers, and under scores, but no spaces or other special characters should be used. For example, custom1, Custom1, and Custom_1 are all valid name constructs, while custom 1 and custom ! are not.
(Attention: you might find that you can use spaces in custom field names and it works in some situations. But this is not advised—and may eventually become impossible anyway—because there are instances where custom field names are used as attributes in other Textpattern tags and thus required to be non-breaking strings, e.g.,
<txp:article_custom customfieldname="value" />. In this example, "customfieldname" represents a custom field name, which must be a single string in this case to work correctly. If the defined custom field name has one or more spaces, it won't work correctly.)
Also, there are certain names reserved by Textpattern, which should not be used to name custom fields, or it could cause your code to not work as expected. Do not use the following for custom field names:
- Any other tag attribute, just in case
A symptom of a name clash is when you go to check or display the contents of a custom field and receive unexpected (or no) output. In this case, make sure your custom field names are not any of the reserved names listed above.
To remove a custom field, simply clear its name. Don't forget to save changes made in the panel.
Syndicate article excerpt only?
If this is set to "No", then feeds will always contain the full article bodies. If this is set to "Yes", feed items will contain an excerpt instead of the article body where it is available.
How many articles should be included in feeds?
This is the maximum number of current articles to be syndicated at a time, in RSS/Atom format. Recommended: a low value, such as 5 through 15
Show comment count in feeds?
When set to "Yes", this setting will append the number of comments to your article titles in your XML feeds.
Include email in Atom feeds?
This allows you to include the email address of the author (as set in their user account) of an article in the author part of your Atom feeds.
Use email address to construct feed ids (default is site URL)?
Feed items in Atom, require a unique ID. To generate IDs unique to your site, Textpattern allows you to choose between either an email address or your domain name to include in these IDs. The email address will be the first one used when creating the site. Unless you are likely going to be changing your domain name, it is probably safe to set this to "No".
Prevent widowed words in article titles?
In typesetting, a "widow" refers to the last word in a given block of text that happens to wrap to the next line by itself. Allowing widows in printed work is generally considered a visually sloppy thing to do.
By default, Textpattern prevents widow words from happening in article titles by automatically adding a no-break value between the last two words. So instead of a widow, there will be two (or more) words on the last line, or none at all, depending on your word count and the width of the containing element of your titles.
This preference allows you to turn that functionality off by saying "No". As a result, your titles will wrap without interference. This may be more preferable if your page layout is responsive, as titles with a no-break between two long words could potentially break the layout at smaller screen widths, resulting in text spilling out of the container area.
Articles use excerpts?
By choosing "No" the excerpt field will not be shown to the author on the article-editing screen.
Allow form override?
This setting allows article authors to override the form to be used when their article is rendered. If enabled, an "Override form" dropdown will be available under "Advanced Options", when editing an article.
This setting will attach a dirified version of your article-title to your URL, it is either generated automatically or can be manually overriden in the "Advanced Options" when editing an article.
This setting will only have an effect when you are using clean urls. For certain languages this may result in long and ugly URLs, in which case you probably want to set this to "No".
This setting only has an effect when "Attach titles to permalinks" is set to "Yes". When dirifying article-titles for use in URLs, you have the option of:
- Using all lowercase letters, and replacing spaces with hyphens.
- Completely removing spaces, and using CamelCase, which means that the beginning of new words will be marked by uppercase letters.
Send "Last-Modified" header?
When set, Textpattern will read a visitor's HTTP If-Modified-Since header (if one exists) and compare it to the last site update. If nothing has changed since the visitor last loaded the page (i.e., if the timestamp the browser sends is the same as the last site update), then a header is sent back instructing the visitor's browser to use its cached version of the page.
This can reduce bandwidth consumption, page load times, and reduce the load on the webserver.
Publish expired articles?
When set to "Yes", expired articles will continue to show on your site after their expiry date has elapsed. You can use if_expired to show alternate content or markup for expired articles.
When set to "No", expired articles will be removed from the public site and return a "410 Gone" HTTP status instead. Visitors hitting an expired article will be shown a custom page template named "error_410" if it's present .
Compensate for persistent connections mod_deflate bug?
Some mod_deflate versions have a bug that breaks subsequent requests when keep-alive is used. Dropping the connection is the only reliable way to fix this. Setting this preference to "Yes" will close the connection, forcing the browser to reconnect for the next request.
Whenever you publish a new article, Textpattern will send a ping to ping-o-matic. Recommended: "Yes" for live sites, "No" for sites in development.
This will send a ping to textpattern.com whenever you publish a new article. Recommended: "Yes" for live sites, "No" for sites in development.
Logs expire after how many days?
When you are using Textpattern for logging, you can set how long (in days) those logs should be kept. "7" will keep the logs available for seven days.
This setting only has an effect, when "Logging" in "Site Preferences" is turned on. Using DNS will allow you to translate IP adresses in your logs to host-names. For some servers this might subjectively slow down your site, in which case you might want to turn this off.
Maximum URL length (in characters)
This prevents URLs that are longer than specified from functioning. It could be helpful in damage limitation.
This allows you to turn off support for plugins. You might want to do this if you find strange errors happening on your site, and you want to make sure that it is not the fault of plugins.
Use admin-side plugins?
Admin-side plugins are those which can change the operation of the administration interface. They might hook into already existing actions, like editing or publishing articles, or they might add new tabs for added/extended functionality.
Allow PHP in pages?
When enabled, this setting allows PHP code within page and form templates. PHP code must be without both opening and closing PHP tags, and enclosed within php tags.
Allow PHP in articles?
When enabled, this setting will allow use of PHP within articles. The author must have sufficient privileges to do so. PHP code must be both without opening and closing PHP tags, and enclosed within php tags.
Allow raw php?
When enabled, this setting allows raw PHP code to be used. Normally this isn't allowed, and PHP code must be without both opening and closing PHP tags, and enclosed within txp:php tags. This setting is for backwards compatible purposes only, and it is recommended to be set to "No".
