Re: etc_query: all things Textpattern
Hey Oleg
So far the A-Z works wonderfully and because it worked so well I was asked if it could parse for current category.
Category2 in my case has ‘‘fiction’, ‘drama’
I got as far as this.
<!-- alpha list display A-Z-->
<txp:variable name="current_category" value="<txp:category />" />
<txp:variable name="current_category" />
<txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"
data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = 'books' AND Category2 = 'drama' ORDER BY alpha"
>
<a href="<txp:site_url /><txp:section />/<txp:category />/?alpha={alpha?}">{alpha?}</a>
</txp:etc_query>
<!-- output alphalist and get articles ids when necessary -->
<txp:etc_query globals="_GET" data='<txp:variable name="alphalist" />'
query="//a[text() = '{?alpha|A}']"
replace="&=<span class='active'>{?alpha|A}</span>"
>
{//ul}
<txp:etc_query name="ids" break="," globals="_GET"
data="SELECT ID FROM textpattern WHERE UPPER(SUBSTRING(Title,1,1)) = '{?alpha|A}' AND Status = 4 AND Section = 'books' AND Category2 = 'drama' ORDER BY Title" />
<txp:else />
<txp:variable name="alphalist" />
</txp:etc_query>
<txp:hide>
<txp:if_variable name="ids">
<!-- Pagination bar -->
<txp:etc_query name="pages" data="{?ids|1|substr_count($|,).+1./2.ceil}" />
<txp:etc_pagination pgcounter="page" link="Page {*}" wraptag="nav" break=" | "
pages='<txp:variable name="pages" />' />
<!-- articles output -->
<txp:article_custom id='<txp:variable name="ids" />' limit="2"
offset='<txp:etc_offset pgcounter="page" pageby="2" />' />
</txp:if_variable>
</txp:hide>
<!-- End alpha list -->
First I couldn’t get the the <txp:variable name=“current_category” /> to work. So I tried just for the specific case ‘drama’ which still does not work the way I want.
Current code above does this:
URL…textpattern455/books/
(with code directly above shows “A-Z” and Category drama [which makes sense] but what I want is this to show all books)
URL…textpattern455/books/?alpha=B
(with code directly above shows “B” drama but what I want is this to show all “B” books)
URL…textpattern455/books/drama
(shows entire list of drama but what I want is “A-Z” drama )
URL…textpattern455/books/drama/?alpha=B
(shows entire list of drama but what I want is “B” drama)
My original code prior (listed in message above this one) was wrapped in this:
<txp:if_article_list>
<txp:if_section name=“books”>
<txp:if_category name=” “>
<txp:output_form form=“alpha_list_display” /> (links to the code in the previous message above)
</txp:if_category>
</txp:if_section>
</txp:article_list>
Now it is just this:
<txp:if_article_list>
<txp:if_section name=“books”>
<txp:output_form form=“alpha_list_display” /> (links to the code in this message)
</txp:if_section>
</txp:article_list>
I am wondering if I have to have a separate “category_alpha_list_display” and I would have to call it at this level?
<txp:if_article_list>
<txp:if_section name=“books”>
<txp:if_category name=” “>
<txp:output_form form=“alpha_list_display” />
<txp:else>
<txp:output_form form=“category_alpha_list_display” />
</txp:if_category>
</txp:if_section>
</txp:article_list>
So can I get a query that works for this “URL…textpattern455/books/drama/?alpha=B “ and does it need to be separate from the original query that worked for “URL…textpattern455/books/”
Regards
Leslie

Re: etc_query: all things Textpattern
Hi Leslie, let’s see. Textpattern has no native section/category
url mode, so I presume you are using some rewrite rule or plugin? Some of them (like gbp_permanent_links
or smd_tags
) change internal Textpattern variables and potentially can perturb others work, but let’s assume they play well here. So, <txp:category />
on books/drama
page should output “drama” (please check). If so, use single quotes in your <txp:variable />
definition:
<txp:variable name="current_category" value='<txp:category />' />
<txp:variable name="current_category" />
Now, replace Category2 = 'drama'
with
Category2 LIKE '<txp:variable name="current_category" />%'
in both db queries. That’s a bit fragile, since it will also match dramatic+art
on books/drama
page, but ok for testing. Please report back whether it fixes some points or not, and we will see the rest.

Re: etc_query: all things Textpattern
Hey Oleg
I can’t get a <txp:variable /> to work in the code. The best I have managed is this output, this case <txp:variable name=“currentcategory” /> is “fiction” [Category2 LIKE “fiction%”]:
<txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"
data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = 'books' AND Category2 LIKE "fiction%" ORDER BY alpha"
Which is produced from this code:
<txp:variable name="currentcategory" value='<txp:category />' />
<txp:variable name="currentcategory" />
<txp:variable name="ids" />
<txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"
data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = 'books' AND Category2 LIKE "<txp:variable name='currentcategory' />%" ORDER BY alpha"
I think I have tried every variation on single and double quotes, and this is the only version I have come up with that actually makes an etc_query call. They either threw back syntax errors or failed silently with no etc_query call happening at all.
If I don’t use double quotes and use single quotes like this
Category2 LIKE '<txp:variable name='currentcategory' />%'
I get this error:
Tag error: <txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"
data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = 'books' AND Category2 LIKE '<txp:variable name='currentcategory' />%' ORDER BY alpha"
and this version fails silently without etc_query even being called.
Category2 LIKE '<txp:variable name="currentcategory" />%'
Solving this variable call sure would be nice as I could hard code the category but defeats the purpose of a dynamic CMS.

Re: etc_query: all things Textpattern
Right, sorry, try to nest duplicated single quotes:
<txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"
data='SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = ''books'' AND Category2 LIKE ''<txp:variable name="currentcategory" />%'' ORDER BY alpha'>

Re: etc_query: all things Textpattern
Unfortunately duplicate single quotes fail silently.
<txp:output_form form="alpha_list_display" />
[SQL (0.000259876251221): select Form from txp_form where name='alpha_list_display']
[Form: alpha_list_display]
<txp:variable name="currentcategory" value='<txp:category />' />
[attribute 'value']
<txp:category />
[/attribute]
<txp:variable name="currentcategory" />
<txp:variable name="ids" />
[<txp:variable>: Unknown variable 'ids']
<txp:variable name="currentcategory" />
[txp:etc_query SHOULD APPEAR HERE but NOTHING everything after this point is dumped]
<txp:site_url />
<txp:section />

Re: etc_query: all things Textpattern
Oleg
Even if we can’t solve the variable issue. I thought I would point out that this works
URL …textpattern455/books/drama/?alpha=E for me when hardcoded and beautifully if I might add.
I am not using a plugin to get there, unless it is an unintended consequence (I don’t think so) and I don’t think I am using a rewrite rule, see below. But to be frank I have been piecing/adding/improving this code together for years I forget how some parts happened. At one point I noticed that instead of coding for this “http://textpattern.site/section/?c=sitemaps” I could code for this “http://textpattern.site/section/sitemaps” and it passed the category through.
I had just thought it was a new feature.
In the same way this works on textpattern tip site:
http://textpattern.tips/category/tutorials = http://textpattern.tips/?c=tutorials
Probably only when your preference for permanent link mode is /section/title (maybe/maybe not/haven’t tried)
Here is my .htaccess
#DirectoryIndex index.php index.html
#Options +FollowSymLinks
#Options -Indexes
#ErrorDocument 403 default
<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /relative/web/path/
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+) - [PT,L]
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*) index.php
RewriteCond %{HTTP:Authorization} !^$
RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]
</IfModule>

It’s different: category
has a special meaning (in English) for Textpattern, it’s not a section name. If you go to www.textpattern.tips/articles/?c=css, you will get all CSS tips from articles
section. But www.textpattern.tips/articles/css will output all articles.
Back to variables, could you post the relevant code block? Looks like a syntax error somewhere.

That’s normal, you need single quotes for tags in tags. Please try
<!-- alpha list display A-Z-->
<txp:variable name="currentcategory" value='<txp:category />' />

<txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"

Weird, it’s working for me… could it come from somewhere else? What if you comment out this code, wrapping it in <txp:hide>...</txp:hide>
?

Re: etc_query: all things Textpattern
Excluding other code.
This works:
<txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"
data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = 'books' AND Category2 LIKE 'drama' ORDER BY alpha"
>
This doesn’t:
<txp:etc_query wraptag="ul" class="pull-right breadcrumb" break="li" name="alphalist"
data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = 'books' AND Category2 LIKE ''<txp:variable name="current category" />%'' ORDER BY alpha"
>
Is there a working example of a variable txp or any other type that I can pass through with etc_query?
