## 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).

## Screenshots ##

1. Here's a screenshot of it in action

## 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
 ** ex: `title=>"My Product Reports Page"`
 * `table`: the table we wish to display / edit
 ** ex: `table=>"wp_my_custom_table"`
 * `id`: the admin interface id (defaults to table)
 ** ex: `id=>"custom_table_interface_1"`
 * `id_column`: the column in each row that names the id for the row
 ** ex: `id_column=>"id"`
 * `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.
   `dataFn` is called with the arguemnts array to add_db_table_editor;
 ** ex: `dataFn=>"myCustomInterfaceFunction"`
 * `jsFile`: the name of a registered script that will be enqueued for
   this interface
 ** ex: `jsFile=>"my-custom-interface-js"`
 * `cap`: the capability a user needs to view/edit this interface,
    defaults to edit_others_posts
 ** ex: `cap=>"edit_others_posts"`
 * `editcap`: the capability required to edit the grid, if not set
    all viewers are assumed to be editors
 ** ex: `editcap=>"edit_others_posts"`
 * `noedit`: turns off the editing abilities (same as editcap=nosuchcapability)
 ** ex: `noedit=>true`
 * `columnFilters`: Default column filters, this is an array of column->val
   to be applied as default column fitlers when the page is loaded
 ** ex: `columnFilters=>Array("Year"=>"2017")`
 * `columnNameMap`: A map of actual column names to displayed label
 ** Ex: `columnNameMap=>Array('column_name'=>'Column Alias')`
 * `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)
 ** Ex:`noedit_columns=>"data,id"` or `noedit_columns=>Array('data', 'id')`
 * `save_cb`, `delete_cb`: function names to be called with an array of data:
   the dbte, update array, column array and modified indexes array
   `call_user_func($cur->save_cb,Array('table'=>$cur, 'update'=>$up,
                  'columns'=>$cols, 'indexes'=>$idxs, 'id'=>$id));`
   `call_user_func($cur->delete_cb,$cur,$id);`
   If your call back inserts data it should fill in $data['id'] and accept data
   by reference
 * `auto_date`: should columns that appear to be datetimes, be treated as such
   This is based on the columns data type
 ** Sort of buggy but allows some different date formats than iso8601
 ** Ex:`auto_date=>true`
 * `autoHeight`: passes the autoHeight option to slickgrid (makes
   there not be a vertical scrollbar on the grid and instead in the
   window)
 ** Ex:`auto_height=>true`
 * `async_data`: request data asyncronously instead of inlining
   it. Makes slow queries "seem" faster.
 ** Ex:`async_data=>true`
 * `default_values`: an a_array of default values that new rows should have
 ** Ex:`default_values=>Array("name"=>"First M Last")`
 * `export_id_field`: the field to use when limiting the export results
 ** some sql needs a specific field - defaults to `table`.`id_col`
 ** Ex:`"export_id_field"=>"mytbl.fooid"`

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).

## Adding an Interface from a plugin ##

If you need to add an interface from a plugin, you should use the
`db_table_editor_init` action.

eg: `add_action( 'db_table_editor_init', 'my_load_tables' );`

Inside of the `my_load_tables` function you would include all the
calls to add_db_table_editor


## Custom Buttons

Buttons can be created by pushing functions into
`DBTableEditor.extraButtons`.  Each of these is a slick grid
rowButtonFormatter and should return a string of html.

eg:
   out += fn(row, cell, value, columnDef, dataContext);

The button column width can be set by setting:
DBTableEditor.buttonColumnWidth before the ready function is called


# Hooks / Actions #

 * `db_table_editor_init` is called during init so that other plugins
   can rely on this

 * `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');
```

## dbte_row_saved, dbte_row_deleted

Called after a row is deleted, updated, or inserted passes

```
add_action('dbte_row_deleted', 'my_dbte_row_deleted', 10, 2);

function my_dbte_row_deleted($currentTable, $idRemoved){
  // do things
}

add_action('dbte_row_saved', 'my_dbte_row_saved', 10);

$args = Array('table'=>$cur, 'update'=>$up,
              'columns'=>$cols, 'indexes'=>$idxs, 'id'=>$id));`
function my_dbte_row_saved($args){
  // do things
}

```

# 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!

### FAQ ###

 * I dont see any interface / nothing changed?
 ** Did you complete the installation process, including appropriate
    `add_db_table_editor` calls?
 * My delete button is missing / I Can't Edit
 ** You either dont have `editcap` or `id_column` is misconfigured

# Advanced Examples

## Custom Javascript and Buttons on the table editorcc

See: examples/custom-buttons-and-js.php
     examples/custom-buttons.js

Shows how to add custom javascript to a report page and adds a custom
load button on the grid


## CF7 DB Submit Plugin integration

See: examples/cf7dbsubmit_integration.php

This is not a fully runnable example, but should give good examples of

 * working cf7dbsubmit plugin
 * Custom save delete hooks
 * custom complex sql building with this plugin
 * sending notifications on edit of specific fields

cf7dbsubmit stores its data in a "hashtable" format of:

   form, submit_time, field_name, field_value
 
but we want to present this in a more excel fasion of each field being
a column of our spreadsheet and each row being a different submission
