[PAGINATE] cntprt [PB] cntprt [/PAGINATE]

[jsw_nz]

As part of developing a personal project, came up with a way to 'paginate' contentparts -
allows you to create multiple page articles -- the topic has been disucussed elsewhere on boards
- in fact goes back some time.

USAGE:
place code in separate html content parts. Needs opening and closing tags:
[PAGINATE] & [/PAGINATE]

then use [PB]
to create multiple page breaks

Code Scheme:

Code: Select all

[PAGINATE] contentpart_1 [PB] contentpart_2 [PB] contentpart_3 [/PAGINATE]

Here is Backend Screenshot:


Here is Frontend Screenshot:


Code:

Code: Select all

<?php
define ("REWRITE_ext", ".phtml");
/* if using rewrite two additional rules need to be placed in .htaccess -
also order is important - /subdirectory example is shown here - same would apply to rules for root
RewriteBase /subdirectory
#new
RewriteRule ^([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)_([0-9]+)\.phtml$ /subdirectory/index.php?id=$1,$2,$3,$4,$5,$6&p=$7

Name file as paginate_content.php
place in phpwcms_template/inc_script/frontend_render directory
(please note special instructions if using with rewrite = on)
beta atm - not tested in summary yet.

Just posting this as is - maybe someone will find useful.

Yes this sound good... can you give me more details ..on how to install it?

Thanks

[culda_a]

or is there a way to do this automaticly and to say after 1000 characters to create automatic a second page?

[sustia]

Hi jsw_nz, nice one

[volkman]

@ jsw_nz
wow, thats a good one, thx a lot!!

@culda_a (installation)
read the posting, its all in there

Hi jsw_nz, I don't understand well the usage with rewrite_mode.

I've putted this new rules in my .htaccess

Code: Select all

RewriteRule ^([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)_([0-9]+)\.phtml$ index.php?id=$1,$2,$3,$4,$5,$6&p=$7
RewriteRule ^([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.phtml$ index.php?id=$1,$2,$3,$4,$5,$6

I have deleted the /subdirectory/ because my installation is in the root dir, but seems it doesn't work

[jsw_nz]

Hi Sustia,

Well, while developing the rewrite code i did notice that the order of the arguments does make a wee difference - your post looks correct - other than having excluded the 'non-numeric' rules for aliased page requests. For the sake of arguement - I installed a copy of my install into the root of my localhost - and it works, at least in this environment. Here is the order I had in root level .htaccess:

Code: Select all

RewriteRule ^([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)_([0-9]+)\.phtml$ index.php?id=$1,$2,$3,$4,$5,$6&p=$7
RewriteRule ^([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)\.phtml$ index.php?id=$1,$2,$3,$4,$5,$6
RewriteRule ^(.+)_([0-9]+)\.phtml$ index.php?$1&p=$2
RewriteRule ^(.+)\.phtml$ index.php?$1

I have yet to test this in an actual online setting - i have been tasked atm - so wont be able to get to this until the weekend. I do admit the rewrite issue is a bit fuzzy. Might be other issues at stake here. Perhaps others in the community (hello DeXXus) - might offer additional advice - hope this helps - and as mentioned - the code as it is - is beta - so any improvements are welcome. Planning to include a nav bar icon scheme - like teaser reptag - at some stage.

All the best,
-john-

Hi jsw_nz, now it works perfectly, thaaaanks a lot

[tinoo]

V-E-R-Y nice one, John. Thanks! I started already thinking about where i can use this enhancement a.s.a.p....

The concept behind is very nice - but the solution sub-optimal. A pagination setting is coming for structures and articles - then you can decide to have pagination for article lists and/or for articles based on the content parts too.

Hi Oliver,

"A pagination setting is coming for structures and articles"
Sounds excellent

This advice, coming from the master himself, is well recieved !

All the best - the community is behind you

[kubens]

Normally I would also say that it make no sense to paginate one article, but of course sometimes it is necessary or the most elegant solution to solve either a problem or a customer request I solved a similar issue with custom blocks. This gaves you the ability to structure your articel in separate logical parts.

Details
Preise

Both links belongs to the same article, but pending of the parameter 'show' the template controls which custom block should rendered.

I have folow the instruction I I have use the paginate to paginate a images content part ...but is not working...in frontend it shows me like this:

[PAGINATE]

the content of the images (the images that i put in)

[PB]

the content of the images (the images that i put in)


[/PAGINATE]

any ideea why?

I have paginate_content.php
place in phpwcms_template/inc_script/frontend_render directory

do I have to do other changes?

[jsw_nz]

Hi culda_a,

As mentioned this approach is beta, until OliG provides a core method.
You are absolutely right - tried your code and got the same issue...

From what I am learning (still a student) preg_replace is a string method,
so if it encounters \n or other types of markup that OliG's code generates, it fails to return a pattern.
The workaround i created is to strip out such:

UPDATED - See OliG's post later in this thread:

Code: Select all

if( ! (strpos($content["all"],'[PAGINATE]')===false)) {
	$content["all"] = preg_replace('/\[PAGINATE\](.*?)\[\/PAGINATE\]/se', 'show_page("$1");', $content["all"]);
}

This is working on my localhost...
although page source is a wee bit harder to read
(ps - will add some \n's to the parsing function at some stage)


I updated the code (see above)
cheers,
-john-

BTW: I understand your interest in this -- wanting to create
multiple paginated image galleries - now possible
- just tested now -
thats way cool
