Re: [Apc-aa-coders] AA bug: _AA_CoLoN_ etc.

Hi Norbert,

Strange, it works for us well in php5, so it is probably php4 related
problem.

Special characters are not quoted (replaced by _AA_* strings) on storing
to the database. The text in database is exactly the same, as you type
to the form. The special strings we use during displaying (unaliasing)
AA string.

The unaliasing works this way:

Ex: some text {ifset:{_#HEADLINE}:<h1>_#1</h1>} here
//  say that healdline is "I'm headline (with {brackets})")

1) unalias innermost curly brackets.
It is {_#HEADLINE}, so the by unaliasing this we get:

Ex:  I'm headline (with {brackets})

But we do not want to put such string instead of {_#HEADLINE}, since
then would be the inner most curly brackets the {brackets} string. We do
not want to unalias inside headline text, so we replace all the control
characters by substitutes:

Ex: some text {ifset:I'm headline _AA_OpEnPaR_with _AA_OpEnBrAcE_brackets_AA_ClOsEbRaCe__AA_ClOsEpAr_:<h1>_#1</h1>} here

2) Then we continue with standard unaliasing for inner most curly
brackets, so we get:

Ex: some text <h1>I'm headline _AA_OpEnPaR_with _AA_OpEnBrAcE_brackets_AA_ClOsEbRaCe__AA_ClOsEpAr_</h1> here

3) after all we replace back all the substitutes:

Ex: some text <h1>I'm headline (with {brackets})</h1> here

See: /include/stringexpand.php3 - function QuoteColons()
