Migration Documentation

Reported by peters@slx-online.biz | March 15th, 2015 @ 10:11 AM | in User issues

I am planning to migrate a 0.9x site to the latest version of Exponent. Before working on the live site, I have created a sub-domain to test the process and copied all of the 0.9x files across, creating a copy of the database too. The sub-domain throws a load of errors, I have searched for the old documentation but the site oldsite.exponentcms.org has disappeared. Your web page http://exponentcms.org/exponent-documentation.htm suggests it should still exist. Please advise. I tried to run the install file but that also drops back to index.php with the same errors. The errors start as follows:

Warning: Creating default object from empty value in /home/linweb37/d/devel.britishtrolley.org.uk/user/htdocs/subsystems/sessions.php on line 170

Strict Standards: Non-static method navigationmodule::levelTemplate() should not be called statically in /home/linweb37/d/devel.britishtrolley.org.uk/user/htdocs/subsystems/core.php on line 65

Strict Standards: Non-static method navigationmodule::levelTemplate() should not be called statically in /home/linweb37/d/devel.britishtrolley.org.uk/user/htdocs/modules/navigationmodule/class.php on line 342

Then a whole lot of similar errors, presumably trying to build the menus, followed by what's in the attached screen shot.

Really sorry to bother you with 0.9x stuff, but without any docs I don't know where to start, and I dare not try migration without testing and understanding the process fully.

Thank you.

    Hi Dave. I've worked out the major problem is the PHP version - it's 5.4 on the test server and needs 5.3 Have installed a local server and now working. So please ignore references to errors above.

    I've tried running the upgrade install but it says the site is down for maintenance, the database is off-line, and offers a log in option, which I can't presumably because the database isn't connected. Your migration documentation tells me to point at the 0.9x database, but I can't see where to do that, there's no config file that I can see in the install folder.

    I think the migration documentation seems to start a stage or two ahead of where I think I'm at. Am I right in assuming that I need to put the contents of Exponent 2.3.3 download into the Install folder of the site to be upgraded? Then where in the install files do I give it the database info?

    After a lot of messing about, I worked out that the documentation should have told me that migration doesn't start with the existing site, but that you have to remove the old site and install a clean copy of the latest Exponent. Then as part of the installation process you do the migration from the database etc. (My logic was that if you are migrating you start with what you have and work from there). I know it's easy to get so close to something you assume it's obvious, but please can you add this pointer to the documentation to save others the problems.

    I found a bug in framework\modules\migration\views\migration\manage_files.tpl. Line 22 is missing a } at the end of the line, which throws an error - see attached.

    When the migration process finished, I was taken to 'the home page' which was completely without any CSS formatting. During migration I selected the simple theme, although this now need considerable updating to bring the site back to where it is now at 0.9x. After a while the CSS magically returned, but I now find that the content migration process did not work, none of the pages has been populated.

    Thanks Dave. I re-ran the migration and page content is now there. I did find the theme migration page, I fear it may be more complicated than that. My site has the menu down the left hand side, repositioning seems OK moving the menu statement in index.php. I tried some of the alternative tpl files in the index file, ending up with "YUI Side Nav" as producing a left hand menu of broadly the right shape. However the CSS is defeating me, I can't seem to find what is controlling the format of the menu. I have found by experiment a number of CSS tags that affect this menu, but there must be more as it still doesn't do what I want. Where can I find a full list of the yuimenuitem tags used by Exponent that need to be modified? So far I have:

    .yuimenuitemlabel.yuimenuitemlabel-hassubmenu, .yuimenuitem.yuimenuitemlabel, .yuimenuitemlabel.yuimenuitemlabel { padding: 0 5px; }

    .yuimenuitemlabel.current, .yuimenuitemlabel {padding: 0 5px; background-color: #880b00; }

    Another one I do on a voluntary basis as well!

    Thanks Dave. That's helped so far but there's still a stubborn refusal to do what I want on a Visited link... The black text on the attached capture are the visited links. I think I may need to scrap this and build my own left hand menu, before I go insane! I couldn't find an alternative one in Exponent's various options.


    I've now imbedded my own menu, works fine. Sorry to have bothered you on that one!

    Dave. Please can you help me with the logic that builds a menu from the Exponent pages. I'm almost there but one thing refuses to cooperate.

    I have modified the "showall_YUI Side Nav.tpl" file to use the menu structure and CSS from the 0.9x site. Very simply, if a menu item has no children the class is "navlink" and if it has children the class is "navlink haschildren". If there are children, the background image in the menu has a right arrow, if not then no arrow.

    This is working fine, until you get to the last menu item in a children or grandchildren sub-menu. Although this may have no children, it always has an arrow is displayed.

    The tpl file is attached, together with a screen shot which shows the values on the menu of the two variables "$sections[$nextkey]->depth" and "$section->depth" which are used to increment and select the correct class. My assumption was that if $sections[$nextkey]->depth == $section->depth then that was the last one in the list, but looking at the screen shot the last item in the child and grandchild menus, the variable "$sections[$nextkey]->depth" is decremented by 1, thus screwing up my logic.

    Please can you explain why the last item is different to the rest. I need to be able to prevent the 'haschildren' there except where there is a further menu.

    Thank you.

    I've coded a work-around, but would still like to know the logic behind that last menu item!

    {elseif $sections[$nextkey]->depth < $sections[$key]->depth}

    Thanks Dave. My work-around does seem to work fine. Here's my CSS, it also picks up the yui stuff as if I hadn't made my own changes... Peter.
