[Solved] Generate outline of a wordpress article (updated)

[Zonglars]

I’m working on a blog right now and I want to write a function that automates something I plan on doing with my articles:

– Locate all of the headers, add a unique ID to them
– Generate a nested list based on the level of each header, and each list item links to it’s respective header

I’ve already solved most of it:
– scan the content for headings
– get the level # of each heading
– get the internal text of the headings
– create a list of the links, each one linking to it’s respective heading *
– insert the unique ID into each heading

I’m not sure how to make a nested list based on the levels, that’s all that’s left.

here’s my code so far:

Code:

$post;//already declared through get_post(ID) function

//match all starting with , any character(s), then
$headpattern=”|(.+)|”;

//strip all tags from the code except the headers, since we don’t need the html tags inside the headers
$newpost=strip_tags($post,’

‘);

if(preg_match_all($headpattern,$newpost,$matches)){//find all matching patterns inside the stripped post content
//matches will return 2 arrays: the first is the full HTML match, the second is the text inside the heading tags (found through “(.+)”)
$i=0;
// get the heading level pattern
foreach($matches[0] as $html){
//get whatever number comes after the n”;//start the list
$i=1;
foreach($headings as $title){
//create a list item, with a class according to it’s level, with the title, linking to a unique ID for it’s header
//example:

Lorem Ipsum

the class is simply a last resort if it can’t be nested
echo “

“.$title[1].”

n”;
$i++;
}
echo ““;//close the list

$i=1;
// add the new IDs to the headers
foreach($headings as $title){
//insert the id tag into the headers, between the , into the original content
//should return something like this:

$replace=”$1 id=”h”.$title[0].”-“.$i.””$2”;
$post=preg_replace(‘|()|’,$replace,$post,1);
$i++;
}

echo $post;//print the original content
}else{
echo “FAIL!”;
}

So, how can I generate a nested list, preferably using the $headings nested array.

UPDATE: Nevermind, I found something that gave me an idea, here’s the code incase anyone else had trouble with this:

Code:

and write the link
if($i==1){
echo “
• “.$title[1].”“;
  //if it’s h# is less than the previous one (higher level), then it closed the previous
• &
  before opening a new
  • }elseif($title[0]<$previous){ $diff=$previous-$title[0];//how far apart the levels are (might jump from an h5 back to an h2) for($n=$diff;$n>0;$n–){//close
  • s and
    s as many times as the difference between levels
    echo “

  n

  n”;
  }
  echo “

n

• “.$title[1].”“;
  //if it’s h# is greater than the previuos one (lover level), then it opens a new
  before opening a new
  • }elseif($title[0]>$previous){//I’ll just assume nobody will jump from an h2 to an h5, so no diff check here.
    echo “n
    n
    • “.$title[1].”“;
      //finally, if it’s on the same level, it simply closes the previus
    • before opening a new
    • }else{
      echo “

    n

    • “.$title[1].”“;
      }
      $previous=$title[0];
      $i++;
      }?>

And I checked, so long as the structure is in a logical order (i.e. incrementing down the levels) it writes perfectly valid code.
