Problem with updates and meta boxes

    Hello,

    I am having a bit of an issue with updates when using meta boxes inside my theme. I have OptionTree installed as a plugin rather than inside the theme using theme mode so that clients can update OptionTree when a new version comes out. However, if the theme needs meta boxes I am using the code to load the includes/meta-boxes.php file inside the theme.

    When I do an update of OptionTree it goes through the normal process but because it gets deactivated during the update process, an error occurs when it tries to reactivate. The error is as follows:

    Fatal error: Call to undefined function ot_register_meta_box() in […]\wp-content\themes\seasonal\includes\meta-boxes.php on line 254

    The only way to overcome this problem is cancel the loading of the template file in the functions.php file, do the update and reverse the cancelled line. Or, switch to a different theme, update and then switch back. Of course, this is a problem for clients.

    I didn’t activate theme mode because the clients do their own maintenance, so I left it in plugins in order for them to do updates when needed, but the only way to use meta boxes is to integrate it into the theme.

    Anything I am missing?

    Thanks,
    Lee

    I use OptionTree as a plugin in my themes and do not have trouble upgrading when I use meta boxes, it’s likely you’re doing something wrong. Please send me your meta-boxes.php file so I can see what is causing the issue. Send it derek at valendesigns dot com.

    Hi Derek,

    I actually found the solution, but I think this needs a clearer explanation.

    I am using OptionTree in two parts, the first is the Theme Options in the standard fashion as a plugin, the second using meta boxes inside the theme as described in the Documentation, i.e. adding the meta-boxes.php file to the theme and then the line of code to the functions.php file. That line of code being:

    load_template( trailingslashit( get_template_directory() ) . 'includes/meta-boxes.php' );

    There is some method to my madness. I wanted to keep the plugin as a plugin so that the client could update it, but needed to also implement the meta boxes, so I didn’t want to activate theme mode for this reason. The problem came in when updating the plugin, during the process it deactivates the plugin and once it had updated it couldn’t reactivate because it was was giving an error due to the code for the meta boxes. So I just added some code to check if the plugin was active or not, if not, don;t do anything with the meta boxes, if it is then implement the meta boxes. This allows enough time for the plugin to deactivate, update and then activate again:

    include_once( ABSPATH . 'wp-admin/includes/plugin.php' );
if ( is_plugin_active( 'option-tree/ot-loader.php' ) ) {
  load_template( trailingslashit( get_template_directory() ) . 'includes/meta-boxes.php' );
}

    Not sure if it was you had in mind, but it does work.

    Thanks,
    Lee

    Why not just check if ot_register_meta_box exists in your meta-box.php and be done with it?

    if ( function_exists( 'ot_register_meta_box' ) ) {
  // pass ot_register_meta_box() the meta box array.
}
