Created as simplified and lightweight alternative to other PHP frameworks

• simple and straightforward in development and maintenance
• MVC-like
  • code, data, templates are split
  • code consists of: controllers, models, framework core and optional 3rd party libs
  • uses ParsePage template engine
  • data stored by default in MySQL database using db.php
• RESTful with some practical enhancements
• integrated auth - simple flat access levels auth
• UI based on Bootstrap 5 with minimal custom CSS and themes support - it's easy to customzie or apply your own theme
• use of well-known 3rd party libraries: jQuery, jQuery Form, jGrowl, markdown libs, etc...

1. put contents of /www into your webserver's public html folder
2. edit /www/php/config.site.php (or config.localhost.php for development)
3. create database from /db/fwdatabase.sql, /db/lookups.sql and others (if needed)
4. open site in your browser and login with credentials as defined in fwdatabase.sql
5. review log in /logs/osafw.log

/db                  - initial fwdatabase.sql script and update sql scripts
/logs/osafw.log      - application log (ensure to enable write rights to /logs dir for webserver)
/www                 - application public root folder
  /php               - all the PHP code is here
    /controllers     - your controllers
    /fw              - framework core libs
    /models          - your models
    /vendor          - composer libs
    /config.*.php    - settings for db connection, mail, logging...
  /template          - all the html templates
  /upload            - upload dir for public files
  /assets            - your web frontend assets
    /css
    /fonts
    /img
    /js
  /favicon.ico       - change to your favicon!
  /robots.txt        - default robots.txt (empty)

Controllers automatically directly mapped to URLs, so developer doesn't need to write routing rules:

• GET /Controller - list view IndexAction()
• GET /Controller/ID - one record view ShowAction()
• GET /Controller/new - one record new form ShowFormAction()
• GET /Controller/ID/edit - one record edit form ShowFormAction()
• GET /Controller/ID/delete - one record delete confirmation form ShowDeleteAction()
• POST /Controller - insert new record SaveAction()
• PUT /Controller - update multiple records SaveMultiAction()
• POST/PUT /Controller/ID - update record SaveAction()
• POST/DELETE /Controller/ID - delete record (POST body should be empty) DeleteAction()
• GET/POST /Controller/(Something)[/ID] - call for arbitrary action from the controller SomethingAction()

For example GET /Products will call ProductsController.IndexAction() And this will cause rendering templates from /www/template/products/index

highlighted as bold is where you could place your code.

• FW.run()
  • FwHooks.initRequest() - place code here which need to be run on request start
• fw.dispatch() - performs REST urls matching and calls controller/action, if no controller found calls HomeController.NotFoundAction(), if no requested action found in controller - calls controller action defined in contoller's route_default_action (either "index" or "show")
  • fw._auth() - check if user can access requested controller/action, also performs basic CSRF validation
  • fw.call_controller()
    • SomeController.init() - place code here which need to be run every time request comes to this controller
    • SomeController.SomeAction() - your code for particular action
      • SomeModel.someMethod() - controllers may call model's methods, place most of your business logic in models
• fw.Finalize()

• GET /Admin/Users

  • FwHooks.initRequest()
  • AdminUsers.init()
  • AdminUsers.IndexAction()
  • then ParsePage parses templates from /template/admin/users/index/

• GET /Admin/Users/123/edit

  • FwHooks.initRequest()
  • AdminUsers.init()
  • AdminUsers.ShowFormAction(123)
    • Users.one(123)
  • then ParsePage parses templates from /template/admin/users/showform/

• POST /Admin/Users/123

  • FwHooks.initRequest()
  • AdminUsers.init()
  • AdminUsers.SaveAction(123)
    • Users.update(123)
  • fw.redirect("/Admin/Users/123/edit") //redirect back to edit screen after db updated

• GET /Admin/Users/(Custom)/123?param1=1&param2=ABC - controller's custom action (non-standard REST)

  • FwHooks.initRequest()
  • AdminUsers.init()
  • AdminUsers.CustomAction(123) - here you can get params using reqi("param1") -> 1 and reqs("params") -> "ABC"
  • then ParsePage parses templates from /template/admin/users/custom/ unless you redirect somewhere else

• POST /Admin/Users/(Custom)/123 with posted params param1=1 and param2=ABC

  • FwHooks.initRequest()
  • AdminUsers.init()
  • AdminUsers.CustomAction(123) - here you can still get params using reqi("param1") -> 1 and reqs("params") -> "ABC"
  • then ParsePage parses templates from /template/admin/users/custom/ unless you redirect somewhere else

Frequently asked details about flow for the IndexAction() (in controllers inherited from FwAdminController and FwDynamicController):

1. initFilter() - initializes this.list_filter from query string filter params &f[xxx]=..., note, filters remembered in session
2. setListSorting() - initializes this.list_orderby based on list_filter("sortby") and list_filter("sortdir"), also uses this.list_sortdef and this.list_sortmap which can be set in controller's init() or in config.json
3. setListSearch() - initializes this.list_where based on list_filter("s") and this.search_fields
4. setListSearchStatus() - add to this.list_where filtering by status field if such field defined in the controller's model
5. getListRows() - query database and save rows to this.list_rows (only current page based on this.list_filter("pagenum") and this.list_filter("pagesize")). Also sets this.list_count to total rows matched by filters and this.list_pager for pagination if there are more than one page. Uses this.list_view, this.list_where, this.list_orderby

You could either override these particular methods or whole IndexAction() in your specific controller.

The following controller fields used above can be defined in controller's init() or in config.json:

• this.list_sortdef - default list sorting in format: "sort_name[ asc|desc]"
• this.list_sortmap - mapping for sort names (from list_filter["sortby"]) to actual db fields, Hashtable sort_name => db_field_name
• this.search_fields - search fields, space-separated
• this.list_view - table/view to use in getListRows(), if empty model's table_name used

Application configuration available via fw.config->[SettingName]. Most of the global settings defined in config.*.php. But there are several caclulated settings:

In FwDynamicController controller behaviour defined by /template/CONTROLLER/config.json. Sample file can be fount at /template/admin/demosdynamic/config.json This config file allows to define/override several properties of the FwController (for example: as model, save_fields, search_fields, list_view,...) as well as define configuration of Show (show_fields) and ShowForm (showform_fields) screens. Note is_dynamic_show and is_dynamic_showform should be set to true accordingly. There are samples for the one show_fields or showform_fields element:

  //minimal setup to display the field value
  {
      "type": "plaintext",
      "field": "iname",
      "label": "Title"
  },

Renders:

<div class="form-row">
  <label class="col-form-label">Title</label>
  <div class="col">
    <p class="form-control-plaintext">FIELD_VALUE</p>
  </div>
</div>

  //more complex - displays dropdown with values from lookup model
  {
      "type": "select",
      "field": "demo_dicts_id",
      "label": "DemoDicts",
      "lookup_model": "DemoDicts",
      "is_option0": true,
      "class_contents": "col-md-3",
      "class_control": "on-refresh"
  },

Renders:

<div class="form-row">
  <label class="col-form-label">DemoDicts</label>
  <div class="col-md-3">
    <select id="demo_dicts_id" name="item[demo_dicts_id]" class="form-control on-refresh">
      <option value="0">- select -</option>
      ... select options from lookup here...
    </select>
  </div>
</div>

Main and recommended approach - use logger() function, which is globally available. Examples: logger("some string to log", var_to_dump), logger("WARN", "warning message") All logged messages and var content (complex objects will be dumped wit structure when possible) written on debug console as well as to log file (default /logs/osafw.log) You could configure log level in your config.*.php - search "LOG_LEVEL"

Another debug functions that might be helpful are:

1. rw($var) this function will work like var_dump and just dump variable structure and data to browser (with some formatting)
2. rwe($var) same as above, but immediately die to stop script

• naming conventions:
  • table name: user_lists (lowercase, underscore delimiters is optional)
  • model name: UserLists (UpperCamelCase)
  • controller name: UserListsController or AdminUserListsController (UpperCamelCase with "Controller" suffix)
  • template path: /template/userlists
• keep all paths without trailing slash, use beginning slash where necessary
• db updates:
  • first, make changes in /db/fwdatabase.sql - this file is used to create db from scratch
  • then create a file /db/updates/updYYYY-MM-DD[-123].sql with all the CREATE, ALTER, UPDATE... - this will allow to apply just this update to existing database instances
• use fw.route_redirect() if you got request to one Controller.Action, but need to continue processing in another Controller.Action
  • for example, if for a logged user you need to show detailed data and always skip list view - in the IndexAction() just use fw.routeRedirect("ShowForm")
• uploads
  • save all public-readable uploads under /www/upload (default, see "UPLOAD_DIR" in config.*.php)
  • for non-public uploads use /upload
  • or S3 model and upload to the cloud
• put all validation code into controller's Validate(). See usage example in AdminDemosController
• use logger() and review /logs/osafw.log if you stuck
  • make sure you have "LOG_LEVEL" set to "DEBUG" in your config.*.php

• all reports accessed via AdminReportsController
  • IndexAction - shows a list of all available reports (basically renders static html template with a link to specific reports)
  • ShowAction - based on passed report code calls related Report model
• base report model is FwReports, major methods (you may override in the specific report):
  • getReportFilters() - set data for the report filters
  • getReportData() - returns report data, usually based on some sql query (see Sample report)
• ReportSample model (in \www\php\models\Reports folder) is a sample report implementation, that can be used as a template to build custom reports
• basic steps to create a new report:
  • copy \www\php\models\Reports\Sample.php to \www\php\models\Reports\Cool.php (to create Cool report)
  • edit Cool.php and rename "Sample" to "Cool"
  • modify getReportFilters() to match your report filters
  • modify getReportData() to edit sql query and related post-processing
  • copy templates folder \www\template\reports\sample to \www\template\reports\cool
  • edit templates:
    • title.html - report title
    • list_filter.html - for filters
    • report_html.html - for report table/layout/appearance
  • add link to a new report to \www\template\reports\index\main.html
