Issue 4293 - Make Textpattern use our current website content as template

plugin.php

-$template_data = FALSE;

Nit: I guess this should be NULL not FALSE?

[Wladimir Palant, 2016/09/28 10:14:42]

Done.

+$template_data = NULL;
 
 function get_site_template_path()
 {
   global $prefs;
   return $prefs['tempdir'].DS.'site_template';
 }
 
 function read_template_data()
 {
   global $template_data;
 
   $data = file_get_contents(get_site_template_path());
 
   $header = preg_replace('/<\\/header>.*/s', '</header>', $data);
   $header = preg_replace('/<link\b[^>]*\brel="canonical"[^>]*>/s', '', $header);
   $header = preg_replace('/<ul id="language-selector">.*?<\\/ul>/s', '', $header);
   $header = preg_replace('/<li id="language">.*?<\\/li>/s', '', $header);
-  $header = preg_replace('/<a\b[^>]*\bid="hamburger".*?<\\/a>/s', '', $header);

We don't check for the closing `>` after "hamburger"?

[Wladimir Palant, 2016/09/28 10:14:42]

Do we care about it? It is certainly there somewhere but we skip until the
closing </a>.

[kzar, 2016/09/28 10:19:11]

I guess you're right it doesn't matter too much, but in that case it should be
`.*` instead of `.*?` since there should always be at least one character after
"hambuger".

[kzar, 2016/09/28 10:28:26]

Argh, I meant `.+?`...

[Wladimir Palant, 2016/09/28 10:32:48]

You probably mean .+? (still a non-greedy regular expression but one that
requires at least one character). The input is our own code and we don't need to
validate it so the regular expressions are somewhat sloppy in order to be
simpler. I definitely prefer "skip some number of characters without caring how
many" - this way you don't need to check whether your assumption about the
number of characters is true.

[kzar, 2016/09/28 10:39:06]

Yep that's what I meant, sorry. Makes sense anyway, I guess there's no point
over-complicating it.

   $header = preg_replace('/<title>.*?<\\/title>/s', '', $header);
 
   $footer = preg_replace('/.*<footer\b/s', '<footer', $data);
 
   $template_data = array($header, $footer);
 }
 
 function abp_header($attrs, $contents)
 {
   global $template_data;
   if (!$template_data)
     read_template_data();
 
   $header = preg_replace('/<\\/head>/s', parse($contents) . '</head>', $template_data[0]);
   return $header;
 }
 
 function abp_footer()
 {
   global $template_data;
   if (!$template_data)
     read_template_data();
 
   return $template_data[1];
 }
