Attachments: how to rebuild correct order when same images names?

[axe70]

Hello guys. Sorry for my last worry about things when i posted time ago. I hope that my answers do not hurt nobody.
I will try to be smooth from now on, since i understand that often i go for my own way...
Now for the answer

I did an easy function that raw parse a post into WordPress.
It also now parse attachments.
So what i do is to extract attachments that belongs to the post but a problem have come out (i'm looking around to understand what/how phpBB do):
into this function, the code check for the [attachment=1]image.png[/attachment] placeholder, get the image name, search into array of attachments, then associate related attach to the placeholder.
But what about if the post contain more than one

Code: Select all

[attachment=1]image.png[/attachment] [attachment=2]image.png[/attachment]

that are two different images named the same?
I had hope to get the attach id somewhere into the post text, but i see that it is not stored, do not result into the post text.
So what i ask to myself, is how phpBB associate the right image.png to the right paceholder?
It is a sort of check that is done earlier against physical_filename (even i have not understand how at moment in case)?
Thank you!

May it is that ...
[attachment=1]image.png[/attachment]
belong to the image added after attach 2
[attachment=2]image.png[/attachment]
so can be checked against the attach time or id order.
Well, to rebuild things this way, should be not so easy. It require a function that check for the attachment placeholder number, then calculate times of all attachments then ... i hope what i mean is clear (and exact as possible solution).
It is what phpBB do?

P.S sorry, may this post need to be moved to Custom coding forum! move it please, sorry!

P.s
The attachment placeolder id, refer to array key as it is extracted by the attachments table.
specifically this comment made me reverse things in mind as they need to be, to know which files to display inline and correctly pairing with placeholders and so discarding from the array of remaining attachments (if there are) to show on bottom. I think this is the way phpBB manage the thing.
Cheers!

Code: Select all

	// Make sure attachments are properly ordered
	ksort($attachments);
