embed database data in odt file

 the problem

In odt it is possible to insert some database data as fields in a odt file, but when you change data in phpmyadmin I get
1) a correct update in the data source view above the text,
2) not in the odt file (body: where
are the fields): the fields texts remain unchanged, even after doing the
command “update fields” (both from menu and from keyboard: F9, or
shift+ctrl+F9).

a solution

A workaround is to use insert – section to insert a part of a php file via localhost.

  1. you will see in your odt file the content of the (section=div, of the) php file, as in the picture following:
    image description
  2. insert -> section -> link -> file name “http://localhost/[path]/[filename].php” -> section (the “id” name you have chosen in php file, i.g. inserting a <div id=”biblio”>[php/mysql code]</div> the section name will “biblio”)

Of course, you must previously

  • activate a php/mysql server in local
  • and possibly have some knowledge of html/php source code.

avidemux too slow

It’s better use (one of) the following codecs for encoding

  • x264
  • libavcodec MPEG-1/MPEG-2
  • libavcodec MPEG-4
  • Xvid 

so Avidemux will be able to optizmize the CPU usage and will be much faster. And the CPU temperature will be lower.
Cfr.here.

share (embedding) text between odt documents (librewriter)

Impossible use cross-reference or dde-link for more than a paragraph.
So the only way (to share more than a paragraph) are sections:

  1. define the area you want share in the file A as a bookmark;
  2. in the file B insert -> section -> as link – choose the file and the bookmark
  3. the text boormarked in A will be visible in B

n.b.
It is not necessary a master document.

problems with “locale”

In case of problems with locale (i.g. autokey not starting, or a file with non-latin characters not opening) you can try these commands

  • export LC_ALL=”en_US.UTF-8″
  • export LC_CTYPE=”en_US.UTF-8
  • sudo dpkg-reconfigure locales

calculate age from year of birth

There are two ways:

via php

## 2. in php
You can also use php code, as in the following way
(inspired from this page (https://stackoverflow.com/questions/3776682/php-calculate-age), and _slighty modified_: 

    $dob =”$row[anno_nascita]”;
    $age = date_diff(date_create($dob), date_create(‘now’))->y;
    echo “age: $age years
“;

via mysql in phpmyadmin

1.do this sql query:
     select *,year(CURDATE())-year(anno_nascita) age from studenti__classi; 
2. save the result as view
3. and so you will have, in the view, the age (of your students, i.g.) that can work in LibreBase (to connect with that view).
