 +This plugin redirects the current page to another page after a stipulated number of seconds. It requires the user to have JavaScript enabled in order to work to its fullest. However, a redirect link will still be displayed even without JavaScript.
 +===== Installation =====
  
-This [[plugins|plugin]] ​requires the user to have JavaScript enabled in order to work to its fullestHoweverredirect ​link will still be displayed even without JavaScript.+Search and install the plugin using the [[plugin:​extension|Extension Manager]]. Refer to [[:​Plugins]] on how to install plugins manually. 
 + 
 +The default pause time ​before the redirect, and the minimum allowable pause time can be set in the configuration manager. ​  See [[#​pause_before_redirect|below]] for further details

 You can put the GOTO string anywhere in the document, but it probably makes the most sense to put it at the top. You can put the GOTO string anywhere in the document, but it probably makes the most sense to put it at the top.
 +
   ~~GOTO>​wiki:​syntax~~   ~~GOTO>​wiki:​syntax~~
-The above will force the document to redirect to the [[:syntax]] page after the default amount of seconds. You can change the default number of seconds by editing the plugin (by default, this is 10 seconds). 
  
-You can change the number of seconds ​on the fly like so:+The above will force the document to redirect to the [[:​wiki:​syntax]] page after the default number of seconds. It comes set at three seconds. You can change the default number of seconds in the Configuration Manager.

 +It is possible to link to a subheading of the page: 
 +  ~~GOTO>​wiki:​syntax#​subheading~~ 
 +=== Pause before redirect === 
 +  
 +You can change the number of seconds ​before ​the redirect ​like so:
   ~~GOTO>​wiki:​syntax?​15~~   ~~GOTO>​wiki:​syntax?​15~~
 +
 This will redirect the page after a 15 second pause. This will redirect the page after a 15 second pause.
  
-By default, users can't set the pause length to be faster than three seconds, but this can be changed by editing ​the plugin. The reason for the minimum pause length is that if it's too fast, it becomes difficult to hit the 'Edit Page' button before the redirect happens. If you can't edit the page, then it becomes tricky to remove the redirect.+By default, users can't set the pause length to be faster than two seconds, but this can be changed ​in the Configuration Manager ​by setting a new value for the ''​minSeconds''​ option. The reason for the minimum pause length is that if it's too fast, it becomes difficult to hit the 'Edit Page' button before the redirect happens. If you can't edit the page, then it becomes tricky to remove the redirect. ​
  
 ===== Issues ===== ===== Issues =====
-  *When editing a page with the ''​GOTO''​ tag, be careful of hitting the '​Preview'​ button. The preview **will** redirect just the same as the saved page. 
-  *The viewer'​s web browser must have JavaScript enabled in order to automatically redirect. 
-  *Currently, the plugin only works correctly for internal links.

 +===== Updated Version =====
 +There is an updated version of ''​GOTO''​ which has not yet been integrated into the main distribution. It has a feature which had been asked for an several occasions, the ability to redirect to external sites. ​ It also contains an entirely new feature, which is the ability to automatically redirect to user pages on login. ​   ​

-===== Discussion ===== 
-Right now this plugin can only redirect to internal wiki pages. I'd like it to be able to redirect to external pages, but I'm a little hazy on how DokuWiki processes URLs. Any help is appreciated. ​ --- //​[[aormond@gmail.com|Allen Ormond]] 2006-06-30 22:35// 
- 
-I don't see the point of a page with a ~~GOTO~~ and then some additional content. I'd suggest that if a page contains only an internal link, make an HTTP-header (HTTP 301 response code) redirection and then show a "​Redirected from ..." in the destination page. I'm not that convinced on the subject of automatic external redirection. --- //​[[atnbueno@mundoplus.tv|Antonio Bueno]] 2006-07-28 13:25// 
->I agree, that does sound nice. However, there are a couple reasons I didn't use an http header redirection. As far as I know, it's impossible to make a simple syntax plugin to do it (or at least it's beyond my abilities). Also, if the page redirects without being seen, it would become difficult for a user to remove the redirect. Of course, I'd love to see a more elegant solution, but this is working for me for now. ^_^ --- //​[[aormond@gmail.com|Allen Ormond]] 2006-07-29 01:16// 
->>How about a parameter that disables the redirect, e.g. redirect=no?​ 
->>>​I set min and default to 0, and use the ?do=edit to stop the redirect. Granted that's not going to work for all users.. 
- 
-Sorry, but this Plugin is a Crap. Why did you not use the all Wiki Standardcode like :  
- 
-#redirect [[Articlename]] ​ 
- 
-?? 
- 
-The code you use is to complex and nobody can remember this. 
- 
- 
-> You're welcome to do better. ​ 
- 
-> If there actually existed something like an "all Wiki Standardcode",​ we would all be happy to implement and use it. But there is no such thing! 
->> Ever head of [[http://​www.wikicreole.org/​ |Wiki Creole]]? --Fabian 
- 
->>You have to now "#​redirect"​ in the same way like you have to now "​~~GOTO~~"​. 
->>Use "​\inc\lang\en\edit.txt"​ to advice the users if necessary. 
->>The only thing is, that such a basic function should by part of the basecode.

-==== Why not allow to redirect to external sites? ==== 
- 
-Specifying an URL like ''​http://​www.example.com/​path/''​ doesn'​t do what expected. 
-Is it a bug or a feature? 
- --- [[user>​jno|jno]] //​2011/​07/​08 12:27// 
- 
-==== Why not using HTTP redirects? ==== 
- 
-If you add  
- 
-  ob_start(); 
-  ob_implicit_flush(FALSE);​ 
- 
-to ''​doku.php''​ it would be possible to do HTTP redirects by using ''​header('​Location:​ ...'​);''​ , which would have some advantages: 
- 
-  - No need to enable JavaScript 
-  - No extra clicks for visitors, if they disabled JavaScript 
- 
-The issue "​editing a page may be tricky"​ is not right - you can always enter "​pagename?​do=edit"​ manually in the browser - so what's the point? 
- 
-=== User stupidity === 
- 
-Simple - You can't rely on the fact that all users will be able to know how to use the address bar correctly. If you can't access it through visual scanning and mouse clicks, assume 80% of the population will be unable to utilize the feature.

-==== Great ==== 
-Great, this plugin made my day. Only issue is that I cannot remember the syntax, #REDIRECT would have been better. 
- 
-==== Support for Anchors ==== 
-The # character is replaced by %23 in the URL, so I've made the following modification to the render function. ​ This allows the plugin to redirect to a particular section of a page. 
- 
- function render($format,​ &​$renderer,​ $data) { 
- $message = str_replace("​%d",​$renderer->​internallink($data[0],​ $data[0],'',​ true),​$data[2]);​ 
- $message = str_replace("​%s",​$data[1],​$message);​ 
- $renderer->​doc .= $message; 
- $urlArr = split('#',​ $data[0], 2); 
- $url = wl($urlArr[0]);​ 
- if (count($urlArr) > 1) { 
- $url .= '#'​.$urlArr[1];​ 
- } 
- $renderer->​doc .= '<​script>​url="'​.$url.'";​setTimeout("​location.href=url",'​.($data[1]*1000).'​);</​script>';​ 
- } 
- 
-==== Support for external pages ==== 
- 
-Minor modifications which allow: 
-  - external pages to be referenced. 
-  - doesn'​t output the javacode when looking at page preview.
