Cookie Puzzle

[John_T]

Good morning.

Please don't laugh but I am still using Miva and Miva Mia for my local server. Never quite got round to catching up with the 21st Century and probably too old now to bother.

I have a couple of sites using Miva and they have been working fine for many years but sometime in the past year it seems that they have not been writing or reading cookies.

Strange thing is that cookies get read and written no problem if I use IE9 and Firefox but not if I use Chrome or Opera.

Has anybody any ideas?

Thanks in advance

Can you post a link to your website? (FYI - your first 3 posts are moderated, that's why they didn't appear)

Ah - that explains it.

There is a test page at

http://keepactive.net/scripts/test_cookie.html

If cookies are working then the count should increment with each page refresh.

Thanks for your interest.

I haven't approved your follow-on post since it doesn't appear to be a link to a Miva Merchant website.

[John_T]

You are right..

I realised after posting to this area that the correct choice would be

• MivaScript & Miva Merchant Empresa

so I posted there as I am using MIvsScript

I assume that posting is waiting to be moderated.

This is because using a Meta tag to create a cookie has been deprecated in M63, and completely removed in M65 versions of chrome. You should use javascript or create a "Create_Cookie" feature using Miva_Output_Headers() function as Miva Merchant does in the following function:

[code]
<MvFUNCTION NAME = "OutputCookies" PARAMETERS = "cookies var" STANDARDOUTPUTLEVEL = "">
<MvASSIGN NAME = "l.set_cookie_header" VALUE = "">
<MvASSIGN NAME = "l.cookie_pos" VALUE = 1>
<MvASSIGN NAME = "l.cookie_count" VALUE = "{ StructureMembers( l.cookies, l.cookie_names ) }">

<MvWHILE EXPR = "{ l.cookie_pos LE l.cookie_count }">
<MvREFERENCEARRAY NAME = "l.cookie" VARIABLE = "l.cookies">
<MvMEMBER NAME = "{ l.cookie_names[ l.cookie_pos ] }">
</MvREFERENCEARRAY>

<MvIF EXPR = "{ len( l.cookie:value ) OR l.cookie:expires }">
<MvIF EXPR = "{ len( l.set_cookie_header ) }">
<MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ asciichar( 13 ) $ asciichar( 10 ) $ 'Set-Cookie: ' }">
</MvIF>

<MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ l.cookie:name $ '=' $ l.cookie:value }">

<MvIF EXPR = "{ len( l.cookie:domain ) }"> <MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ '; domain=' $ l.cookie:domain }"> </MvIF>
<MvIF EXPR = "{ len( l.cookie:expires ) }">
<MvIF EXPR = "{ isdigit( l.cookie:expires ) }"> <MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ '; expires=' $ Format_RFC1123_DateTime( l.cookie:expires ) }">
<MvELSE> <MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ '; expires=' $ l.cookie:expires }">
</MvIF>
</MvIF>
<MvIF EXPR = "{ len( l.cookie:path ) }"> <MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ '; path=' $ l.cookie:path }"> </MvIF>
<MvIF EXPR = "{ l.cookie:secure }"> <MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ '; secure' }"> </MvIF>
<MvIF EXPR = "{ l.cookie:httponly }"> <MvASSIGN NAME = "l.set_cookie_header" VALUE = "{ l.set_cookie_header $ '; HttpOnly' }"> </MvIF>
</MvIF>

<MvASSIGN NAME = "l.cookie_pos" VALUE = "{ l.cookie_pos + 1 }">
</MvWHILE>

<MvIF EXPR = "{ ISNULL l.set_cookie_header }">
<MvFUNCTIONRETURN VALUE = 0>
</MvIF>

<MvFUNCTIONRETURN VALUE = "{ miva_output_header( 'Set-Cookie', l.set_cookie_header ) }">
</MvFUNCTION>
</code]

Bruce - many thanks for the information.

In spite of much Googling I had not seen anything about this change.

I looked at your code but my version of Miva is so old it is just not up to the job!

I searched around and came across this bit of Javascript which does the job nicely;

<script>document.cookie="c1=99"</script>

I can replace the c1 value using Miva and I can then read the cookie using a function in my version of Miva and the cookie value is then available to my script.

It is probably a crude solution but hey, it works!

Again, thank you for taking the time.

Regards

javascript is fine. the advantage to using the mivascript version is that cookie data is now available as a mivascript global variable.
