Re: etc_query: all things Textpattern

Nothing to be sorry about, that helped me to fix few glitches.

Thanks!

Any advice about the use of regex to allow me to create excerpt from the boby tag properly? My code is:

<txp:etc_query data='<txp:body />' specials="" query="substring(//p[1], 0, 140)" limit="1" wraptag="p" />

…but, of course, it does not cut properly. Cutting after the last entire word before the character 140 would be better.

Edit: it’s maybe even possible to add &hellip;?

Re: etc_query: all things Textpattern

You can register any php (string) function for use with etc_query. I’m not sure this is optimal, but it should work:

<txp:etc_query data='<txp:body />' specials="" functions="preg_replace,trim" limit="1" wraptag="p"
    query="preg_replace('/\w*:::/', '&hellip;', preg_replace('/^(.{140}).+/s', '$1:::', trim(string(p[1]))))" />

Edit: but be careful if you use it inside another etc_query, you might need to protect the {140} part.

Re: etc_query: all things Textpattern

Hi,
I would like to know if there is any chance to make the following code work…
I’m looking for three comma separated image id’s in the article_image field but I can’t make REGEXP work.
Is that possible? Do I need to use the functions attribute? …

<txp:etc_query data="Image REGEXP '^((\d+,)\s*){2}\d+$'" populate="article">
	<txp:article_image />
</txp:etc_query>

Thanks…

Re: etc_query: all things Textpattern

No, but since you are in db mode here, you must use MySQL regexp notations, which are weird. Try (no warranty)

<txp:etc_query markup="db" populate="article"
	data="Image REGEXP '^(([[:digit:]]+,)[[:space:]]*){2}[[:digit:]]+$'"
>
	<txp:article_image />
</txp:etc_query>

Thanks, I’ll give it a try and learn more about MySQL regexp notations after holydays.

I can’t get it work but it is not really important. Thank you for your reply.

Re: etc_query: all things Textpattern

That works for me, but may be server-dependent.

Re: etc_query: all things Textpattern

Hi Oleg (SOLVED)

I am implementing your wonderful A-Z filter / paginated A-Z article list but I am having trouble limiting the database call to specific textpattern section.

Is there a way to adjust this call to delimit textpattern sections?
I have a section called “Books” to be specific.

<txp:etc_query wraptag="nav" break=" | " name="alphalist"
	data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 ORDER BY alpha"
>
	<a href="?alpha={alpha?}">{alpha?}</a>
</txp:etc_query>

I have tried various iterations on the call by adding AND Section = ‘books’ but with no success.

I didn’t realize there were two calls that needed to be changed so the following is the solution.

NEW Code



<!-- alpha list -->
<txp:etc_query wraptag="nav" break=" | " name="alphalist"
	data="SELECT DISTINCT UPPER(SUBSTRING(Title,1,1)) AS alpha FROM textpattern WHERE Status = 4 AND Section = 'books' ORDER BY alpha"
>
	<a href="?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>"
>
	{//nav}
	<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' ORDER BY Title" />
<txp:else />
	<txp:variable name="alphalist" />
</txp:etc_query>

<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>

Re: etc_query: all things Textpattern

Hi Leslie, glad you have solved it. For multiple sections, you can add

Section IN('books', 'news')

to the appropriate WHERE clauses. And if you have expired/future articles, you may need also

 (NOW() <= Expires OR Expires = '0000-00-00') AND Posted <= NOW()
