Temporary Solution for Ordering/Sorting Custom Fields

[Francesko]

Do this modification on your own responsibility!
Make a backup of database & (Field.php , Item.php) files in "\oc-includes\osclass\model\" before doing any changes!


NOTE: After this modification you need to edit manually the order/position for each custom field on the database! You can't do it on oc-admin!
If you add a new custom field make sure to edit the position number or it will be displayed at the top of custom fields!


Requirements:

1.Basic knowledge of PHP and SQL (MySQL).
2.Access to database, (phpmyadmin) or mysql command line.

Tasks:
1.Add a column to oc_t_meta_fields table.
2.Edit files (Field.php , Item.php) in "\oc-includes\osclass\model\"

===========================================
First you need to create a column to oc_t_meta_fields table. To do that, login to PhpMyAdmin, Select the database that you have installed Osclass, click on SQL tab and run this query:

Code: [Select]

ALTER TABLE `oc_t_meta_fields` ADD `c_position` INT(3) UNSIGNED NOT NULL DEFAULT '0' AFTER `b_searchable`;
Warning: If you have changed the default Database Table Prefix don't forget to change the oc prefix from code above! (For example: customprefix_t_meta_fields)

Go to \oc-includes\osclass\model\ and edit:

Field.php:

Find: (Line 62)

Code: [Select]

$this->setFields( array('pk_i_id', 's_name', 'e_type', 'b_required', 'b_searchable', 's_slug', 's_options') );
Replace with:

Code: [Select]

$this->setFields( array('pk_i_id', 's_name', 'e_type', 'b_required', 'b_searchable', 's_slug', 's_options', 'c_position') );

Done!


To edit order/position of the custom field go to phpmyadmin, --> osclass database, select oc_t_meta_fields table and modify the value of c_position.



Hope this helps!

This is like in opencart. You manually enter the position.
1.What happens if you leave them all to 0? It will order them by id?

2. What happens if you add more custom fields after you've made these changes?

@Francesko

I sort of understand what you are trying to say (But my inability to fully comprehend is NOT the reason I am posting here)

The reason for my posting is to compliment you on the way you have described the process !

Using red for the "before" and green for the "after" code.
Your image attachments are also very descriptive.
From the looks of things you may either be a very good orator or a great teacher - either way - very good illustrative display method !!!!

Forum should put like buttons!
Thanks, very use full Francesko
