SQLite has FTT. Could it be a viable alternative database backend for PW?

Recommended Posts

SQLite would be nice, but not really needed. If possible and changes to database abstraction is needed a move to PDO would make it possible.

At the moment it would be interesting because of a small private php project which should run on cheap webhostings without extra features. So sqlite would reduce the requirements *g*
With a small private projects I would try to keep hosting cost low...

But web hostings with mysql isn't expensive today...

@WillyC Haven't checked it... Assumed it because of much work to implement sqlite. So it sounds like compatibility and testing part because pdo sqlite would be possible?

PW db / selectors are awesome and complex. So I' think it isn't an easy part with very low priority...

There are two parts to this. Connection to a database and SQL features/parity in results. Connection to the db is abstracted through PDO and most things in processwire use the PDO powered database connection. In old code you might still find things calling to the old mysqli powered processwire class. 

The part about sql features and their parity in implementation/results is another topic, which requires a good amount of knowledge of both databases. Actually PWs query engine isn't really using many fancy sql features, most stuff is just many joins + conditions, but I don't know sqlite well enough to evaluate if everything will be working there as well.

The easy portability for smaller sites sounds pretty good to me too 😌

I would love to see SQLite support in PW. It would allow me to make my PW dev environment portable. I use my perosnal laptop and work PC for development and carry projects in USB Disk. All of my Nodejs and python projects are portable because they all use portable database files (not the database server instance, the actual data files). I know MySQL allows to specify a --datadir when starting, but this is not very portable (at least not for me). I've tried containerizing php and mysql for PW developement, but didn't work out the way I wanted. It just  doesn't allow me to get started immediately.

If sqlite support is implemented we can use a lightweight portable db in development and migrate to MySQL in production.

      Hello @ all,
      I am creating a new inputfield/fieldtype to store opening hours, but I am struggeling to save values from multiple dynamic created inputfields in 1 column of the database.
      Scenario:
      The user can enter one or more opening times per day in a UI.
      Fe:
      Monday open from 08:00 to 12:00 and from 14:00 to 17:00 Tuesday open from 08:00 to 12:00 and from 14:00 to 19:00 and so on
      Via a little JavaScript you can add as much opening times as you need per day - the additional inputfield will be created dynamically.
      After form submission all the values are in the POST array -> this works (see example below):
      ProcessWire\WireInputData Object ( [openinghours_mo-0-start] => 09:00 [openinghours_mo-0-finish] => 13:00 [openinghours_mo-1-start] => 14:00 [openinghours_mo-1-finish] => 18:00 [openinghours_mo-2-start] => 21:00 [openinghours_mo-2-finish] => 23:00 [openinghours_tu-0-start] => 09:00 [openinghours_tu-0-finish] => 13:00 [openinghours_tu-1-start] => 14:00 [openinghours_tu-1-finish] => 18:00 [openinghours_we-0-start] => 09:00 [openinghours_we-0-finish] => 13:00 [openinghours_we-1-start] => 14:00 [openinghours_we-1-finish] => 18:00 [openinghours_th-0-start] => 09:00 [openinghours_th-0-finish] => 13:00 [openinghours_th-1-start] => 14:00 [openinghours_th-1-finish] => 18:00 [openinghours_fr-0-start] => 09:00 [openinghours_fr-0-finish] => 13:00 [openinghours_fr-1-start] => 14:00 [openinghours_fr-1-finish] => 18:00 [openinghours_sa-0-start] => [openinghours_sa-0-finish] => [openinghours_so-0-start] => [openinghours_so-0-finish] => ) The property name is always the name attribute of the field 😉 . If the property is empty means closed on that day.
      Now I need to combine all those values into 1 array (or json array) and store it in the database in 1 column called 'hours' in my case (see screenshot below):

      In my ___processInput(WireInputData $input) method I have tried to make it work like this:
      public function ___processInput(WireInputData $input): self { $name = $this->attr('name'); $value = $this->attr('value'); //input object includes always every input on the page, so lets filter out only inputs from this field //we need to do this, because the number of values is variable - so extract only values that starts with $name.'_' $nameAttributes = []; foreach($input as $key=>$value){ if(substr($key, 0, strlen($name.'_')) === $name.'_'){ $nameAttributes[$key] = $value; } } // loop through all inputfields of this fieldtype $time_values = []; foreach($nameAttributes as $nameAttr => $value) { $time_values[$nameAttr] = $value; } } //save it in the database $input->set('hours', serialize($time_values)); return $this; } The only important part of this code is the last part with the serialize function.
      After saving it will create a record in the database, but the value is always NULL (default value) (see below).

      Checking $time_values returns all the values, but printing out "$this" shows me that the property "hours" inside the Openinghours object is empty (see below) - so the mistake must be there, but I dont know where?!?!?!?
      [title] => Home [openinghours] => ProcessWire\OpeningHours Object ( [data] => Array ( [hours] => ) ) If I check the sleepValue() method or the sanitizeValue() - they are also empty. So it seems that the values will not reach these methods. I havent found a clear documentation of whats going on behind the saving process of an inputfield.
      As far as I know the saving process starts with the form submission. The values are in the POST array and will be processed by the processInput() method. Before they will be saved in the database they will be sanitized by the sanitizeValue() mehtod and afterwards they will be prepared for storage in the sleepValue() method.  The last step is the storage itself.
      Has someone an idea what is missing by storing values from multiple fields into 1 database column or has someone a working example of such a scenario on github to help me out.
      A clear explanation of the storage process will be also helpful.
      Thanks and best regards

      Hi Everyone 
      I've been working on Processwire for two months now. Structuring the website as needed. Unsure why but I'm getting this one now. Seems my fields has crashed. 
      I've tried googling some answers but can't seem to find a step by step guide on how to rectify this. Any advise? Practically new on this. 
      TIA.

      Hi everyone!
      I have a website in a production environment and I want to duplicate it in a local environment. I exported the content of the website (with the 'Site Profile Exporter' module) but I cannot use it actually. I've got an issue with the database. I imported this one in MAMP then.

      I also exported the pages (with the 'ProcessPagesExportImport' module), but I cannot import it to my local website because the fields don't exist. So I created this fields, but I have this error :
      How can I use the elements that already exist and are presents in my database? How can I duplicate correctly the templates, fields and pages?
      Thanks by advance
      PS: Sorry if my english is bad

      Hello guys,
      I'm trying to figure out how to sync fields and templates between staging and production environments.
      I've found Migrations module by Lostkobrakai, but with use of it all the fields and templates must be created by API, which is kind of uncomfortable.
      I also tried ProcessDatabaseBackups module which can export only certain tables, but I don't think it's the best practice to do that.
      How do you guys solve this problem? It's very annoying to setup everything three times (dev, staging, production).
      Thanks a lot :)

      Hi everybody!
      I have been reading about Multisite, but it kinda bugs me that every topic talks about having both admin and database same for multiple sites.
      I have a project where customer tests it by adding content to the site, while I still need to do some changes here and there in code, maybe some in database. If something crashes for a while, customer can't keep testing, which is a bit problematic.
      Is there any way that I could have two separate versions of one site ("production" and development) that share the same database, but are otherwise independent? Just the thought of having to migrate database every time I want to show client something new gives me anxiety 😁
