pagination problem

Hello,

I have this problem.

Every article has a custom field named pagenr with for example the value 2
When I do on the page template.
<txp:custom field named=“pagenr” value=“3”>

Will the value 2 which is in the database be overwritten by the new value or will it be the old value.

Eh? There’s no such tag. You appear to have combined the if_custom_field and custom_field tags to make a fictitious hybrid :-)

Re: pagination problem

Hello Bloke,

You’re right. I combined custom field with txp:variable
The script im working is not doing what it supposed to do , so back to the drawing table.

Re: pagination problem

Hello,

I have this problem.
I have several articles in a month. Every article has a custom field with the name “pagenumber”

I use a script so every pagenumber is only displayed one time.
Now the problem.
In september 2005 I have pagination of 17 pages where only a pagination of 11 can be displayed.
So i thought I make a script which do the following.

when it’s sept 2005 which has 17 pages.
When I read pages 1 till 4 I have to see a pagination of 1 till 11
When I read pages 4 till 8 I have to see a pagination of the pagenumber -2 till that number + 10
When I read pages 9 till 17 I see a pagination of 6 till 17.

Alll the other months I have to see all the pagination.

Roelof

Can this be done ?

Re: pagination problem

I have made this script :

but on all months the url contains no pagenumber and on sept. 2005 all pagenumbers are 11.

Re: pagination problem

Tag foutmelding <txp:variable name=paginanummer /> -> Textpattern Warning: Attribuut waarden moeten tussen aanhalingstekens on line 984

I understand that you want to strip the whitespace from the page’s source code, but it makes it harder to troubleshoot your code.
My guess is that you put too many tags inside the if_different tags.

Oh, and if you post code that ends with a lot of closing tags, you’d better include the opening tags as well, otherwise it’s impossible to tell whether you closed your tags correctly.

Re: pagination problem

Thank you. Intersting code. I’ll have another look after supper if you don’t mind. Can you tell me what operator=“none” does, I’m not so familiar with smd_if.

Re: pagination problem

Hello Els,

Of course.

Operator none is wrong , it must be not.
Wierd that I get the good outcome.

But I will change it.

Re: pagination problem

Roelof, do you have two custom fields: ‘pagenr’ and ‘my_custom_field_pagenr’? What is in the second?

Re: pagination problem

Hello Els,

It’s the same.
Smd_if can only work with custom fields this way.

Re: pagination problem

Thank you. I went through the first half of your code, and I understand what you want it to do, but it’s not doing that. I put my remarks inside the code (in capitals), so don’t copy/paste it ;) What I did was writing down in ‘human’ language what the tags exactly do, that’s always a good way to check your code. If it doesn’t help you, choose a page number and try and follow how the variables, calculations and conditionals are affecting it.
Remarks are in Dutch – because it’s complex enough as it is, and I don’t expect anyone to be seriously interested in a translation ;)

I think what you have in mind can definitely be done, but I’m not going to rewrite the code for you. I hope my remarks will help you see why it doesn’t work.
