Child themes

On child themes :

In MailPress 5.2,
in mp-content/themes there are now 6 folders :

• _template:
  • contains a “minimalist” mailpress theme
  • this mp theme is the parent theme of following child themes :
    • MailPress
    • nogent94
    • twentyten
  • all mp theme folders starting with ‘_’ will be hidden on all admin page lists or screens.
• MailPress : child theme of _template mp theme (see tag ‘Template’ in MailPress/style.css header).
• nogent94 : child theme of _template mp theme (see tag ‘Template’ in nogent94/style.css header).
• nohtml : theme for plaintext only mails.
• twentyten : child theme of _template mp theme (see tag ‘Template’ in twentyten/style.css header).
• plaintext : hidden default theme for plaintext part of mails. To customize this part of the mail you can copy the plaintext folder IN your mp theme folder (my_mp_theme_folder/plaintext) and adapt it to your needs.

On specific files in your parent/child mp themes :

• functions.php : are required in the child theme in following order : parent, child.
• All template files with tag ‘Template Name’ : if required, searched in following order : child, parent and required once.
• default.php : if no template file required or found (see above), searched in following order : child, parent and required once.
• style.css : if required ($this->get_stylesheet();), searched and integrated in the mail in following order : parent, child.
• style.php : style.php classes will be applied in following order : parent, child.
• special rule for plaintext part : if the searched file is not found in child, parent optional plaintext subfolder, it will be searched in plaintext folder.

On ‘child themes’ api :

• $this->get_template_part(name) : name.php searched in following order : child, parent and required once.
• $this->get_header() : equivalent to $this->get_template_part('header');
• $this->get_footer() : equivalent to $this->get_template_part('footer');
• $this->get_stylesheet() : style.css are integrated in the child theme in following order : parent, child.
• special rule for plaintext part : if the searched file is not found in child, parent optional plaintext subfolder, it will be searched in plaintext folder.

Old mailpress themes should not be impacted, however some tests are always welcomed.
Thank you for your help !
