Description

This is a Wordpress plugin that allows direct excel-like editing of tables in your Wordpress database. It's goals are to provide useful, simple, flexible database table admin screens.

It supports:

  • one table per admin screen, as many admin screens as desired
  • These are organized under a new "DB Table Editor" menu item
  • excel spreadsheet like interface using SlickGrid
  • Filter and Sort results
  • Add, Edit & Delete records
  • Custom buttons extensibility
  • Custom permissions per interface for viewing and editing (defaults to: edit_others_posts)
  • editing defaults to the same permission as viewing if not specified
  • CSV exports of filtered grid
  • Custom primary key names (but must be a single value / column)

Reasons and Expectations

Previously my company had been using DB-toolkit to provide minimal database interfaces for custom tables through the Wordpress admin. While the configuration was cumbersome for what we were doing, it did work and was easier than writing anything. However, when DB-Toolkit stopped being maintained and I couldn't find a simple, but suitable replacement, I decided to tackle my goals more head on

Use of this plugin requires a basic knowledge of PHP, and SQL. It was written by a programmer to help accomplish his work and does not currently provide admin configuration screens (instead simple function calls in your theme's functions file are used to configure the screens). This was preferable to me, because my configuration is safely in source control (a problem I had when DB-toolkit would upgrade and lose all configuration).

Installation

This is installed the same way all wordpress plugins:

  • Drop the unzipped plugin directory into your wordpress install at wp-content/plugins/wp-db-table-editor

  • Activate the plugin via the Wordpress Admin > "Plugins" menu

Adding an interface

DB-Table Editor Interfaces are added by calling the add_db_table_editor function in your theme's functions.php file. This supports wp_parse_args style arguments.

  • title: what shows up in the H1 on the screen and in menues
  • table: the table we wish to display / edit
  • id: the admin interface id (defaults to table)
  • id_column: the column in each row that names the id for the row
  • dataFn: a function that returns the data to be displayed / edited, defaults to select * from {table}. This should return ARRAY_N through wpdb->get_results. Alternatively it may return a DBTE_DataTable;
  • jsFile: the name of a registered script that will be enqueued for this interface
  • cap: the capability a user needs to view/edit this interface, defaults to edit_others_posts
  • editcap: the capability required to edit the grid, if not set all viewers are assumed to be editors
  • noedit: turns off the editing abilities (same as editcap=nosuchcapability)
  • columnFilters: Default column filters, this is an array of column->val to be applied as default column fitlers when the page is loaded
  • columnNameMap: A map of actual column names to displayed label
  • noedit_columns, hide_columns: You may wish to hide some columns or prevent edit. You may do so by setting these fields to the name of columns you wish hidden or uneditable (eg: the id)
  • insert_cb,update_cb, delete_cb: function names to be called with the dbte, update array, column array and modified indexes array call_user_func($cur->insert_cb,$cur, $up, $cols, $idxs);
  • auto_date: should columns that appear to be datetimes, be treated as such This is based on the columns data type

Example:

if(function_exists('add_db_table_editor')){
  add_db_table_editor('title=Employees&table=employees');

  add_db_table_editor(array(
    'title'=>'Event Registrations',
    'table'=>'event_registrations',
    'sql'=>'SELECT * FROM event_registrations ORDER BY date_entered DESC'
  ));

}

Adding an Interface on the fly

If we go to look up a database table editor and we dont find it, but there is a function named dbte_create_$tbl that matches, we will call that function expecting it to return a dbte instance. This is useful in situations where we may not have the data for a table editor in all circumstances (EG: not every page has a member id, so only do it on that particular page).

Hooks / Actions

  • db-table-editor_enqueue_scripts is an action that will be called after enqueueing all plugin scripts and before enqueueing jsFile (if it exists)
function dbTableEditorScripts(){
  wp_register_script('employee-table-extensions-js',
    get_stylesheet_directory_uri().'/employee-table.js',
    array('db-table-editor-js'));
}
  add_action('db-table-editor_enqueue_scripts', 'dbTableEditorScripts');

Shortcodes

You can use a shortcode to include a dbte interface on a wordpress page. Please use with care.

[dbte id=table-editor-id] - (id defaults to table)

== Caveats ==

  • Dont put an editable table editor on your public facing screens using the shortcode!

== Troubleshooting ==

  • My delete button is missing / I Can't Edit
  • You either dont have editcap or id_column is misconfigured
