    PW 3.0.200 – New master/main version

    in News & Announcements

    Posted

    We upgraded a big multi language site to 3.0.200 and to PHP 8* + MySQL 8 a couple of days ago, several thousands pages, lots of templates and fields (120MB DB).

    The upgrade went fine, and the site is running super fast! I didn't measure with tools, but just by reaching the URLs of some complex pages and you can see it loading waaay faster. The client could not be happier.  ?

    Fantastic job, Ryan and the other contributors! 

    Thank you,

    Sergio

    Gatsby - Thoughts?

    in Dev Talk

    Posted

    Great tips from Diogo and I'd like to suggest Hugo (https://gohugo.io/) as a great SSG, specially if you want to explore alternatives to javascript-based ones for two basic reasons:

    1. You don't want to mess with a lot of javascript dependencies fatigue, specially as you go back to edit the project in a few months/years, and things start to break when you try to run the project.

    2. The project will have 100s or 1000s of pages and you want to generate it as fast as possible.

    Global field with one instance needed: Content of footer should be dynamic and changes should affect all pages at once

    Question: is it possible to have one global field in which changes the content for the footer of all pages?

    Hi Daniel! 

    It sure is. A simple way to do it is to have the field on only ONE page, like the homepage or a "settings" page and get this page's field content in your footer template. 

    For instance, if you have this field on your homepage, called "footer_text", you can get it this way: 

    // On your footer.php file

//Get the homepage reference
$homepage = $pages->get('/');

// Let's say your field is called "footer_text"
echo $homepage->footer_text;


// Docs: https://processwire.com/api/ref/pages/get/

    [SOLVED] How to manipulate page title for ONLY the default language?

    in Multi-Language Support

    It doesn't work. The title field is still empty.

    Your code seems to be missing one line: 

    $wire->addHookAfter("Pages::saveReady", function(HookEvent $event) {

  $page = $event->object; //this line

  if($page->template->name != 'mytemplate') return;

  $defaultLang = wire("languages")->get("default");

  $page->title->setLanguageValue($defaultLang, "New Value");

});

    Any suggestion for this ? 

    25,000 per hour/day/week? It all depends.

    From what you described about the app, even 25k users a day should be fine to start with a VPS with 2GB of RAM. If its usage increase a lot you can move the database to another VPS on its own AND/OR increase the VPS CPU and RAM resources very quick.  

    My advice is to keep things simple and not try to over-engineer the application performance from the start. But if you feel "adventurous" ? or think that the project will have this many users right away on day one (which I doubt) you can start with a "serverless" approach where the infrastructure is scaled on-demand, using https://vapor.laravel.com/ and you don't have to worry. There's a course about this approach that is very interesting: https://serverlesslaravelcourse.com/

    #CanWeDoThisWithProcessWire - Online Examination

    in Dev Talk

    typo

    Although doable, I'd only recommend a system like this to be implemented using ProcessWire if the rest of the project must (or already is) be highly coupled with PW and it doesn't make sense to decouple it for whatever reason. Otherwise I'd recommend you to implement it using another framework. PW shines in the content management part, and I love it, but it may present you with some limitations in its developer-experience department when you need to implement some business logic that relies heavily on integration of payment systems, user data input, generation of reports and especially tests. There's also a myriad of similar systems like this already implemented that you can use as a base, like this one https://github.com/LaravelDaily/Laravel-Test-Result-PDF (demo: https://www.youtube.com/watch?v=GmLFHGud7I8).

    Maybe you have an older version of the font installed on your Computer?

    Good call. I checked and I had Rubik installed so I disabled it but the problem remained, maybe I need to restart the computer to work, but I can't do it right now. But I also checked again the website and the only problem appears to be on 300 font-weight. 400 or more are fine ( I changed it to 400 on the Body as a test, screenshot attached).

    Created Date - how to get local timezone of browser? - Page created via API

    in API & Templates

    Hi @Sergio, just for clarity, Carbon will work with what you hand to it, right? i.e., it has no way of knowing a user's (browser client) TZ.

    Hi @kongondo, sure, but he mentioned "logged-in users can publish posts" so I think he can capture the user timezone settings on the server side, and/or, give the user to overwrite this preference on admin.

    EDIT: sorry, I misread it. You are right, @kongondo! my bad!

    Created Date - how to get local timezone of browser? - Page created via API

    in API & Templates

    Posted

    I would go with the great Carbon library and handle the timezone conversion in PHP.

    https://carbon.nesbot.com/docs/#api-timezone 

    $tz = new CarbonTimeZone('Europe/Zurich'); // instance way
$tz = CarbonTimeZone::create('Europe/Zurich'); // static way

// Get the original name of the timezone (can be region name or offset string):
echo $tz->getName();                 // Europe/Zurich
echo "\n";

// toRegionName returns the first matching region or false, if timezone was created with a region name,
// it will simply return this initial value.
echo $tz->toRegionName();            // Europe/Zurich
echo "\n";
// toOffsetName will give the current offset string for this timezone:
echo $tz->toOffsetName();            // +02:00
echo "\n";
// As with DST, this offset can change depending on the date, you may pass a date argument to specify it:
$winter = Carbon::parse('2018-01-01');
echo $tz->toOffsetName($winter);     // +01:00
echo "\n";
$summer = Carbon::parse('2018-07-01');
echo $tz->toOffsetName($summer);     // +02:00

// With no parameters, a default timezone is created:
echo new CarbonTimeZone();           // UTC
echo "\n";
echo CarbonTimeZone::create();       // UTC

     

    filter pages by date field

    in API & Templates

    Posted

    You can filter by dates like so: 

    $events = $page->children('limit=50, date<=today, sort=-date');

    Also check this thread to see more details:
      

    date_start>=today
date_start>=1365436783
date_start>=2013-04-08
date_start>=4/8/2013
date_start>=8.4.2013
date_start>="April 8, 2013"

    [SOLVED] Lost query on search pages

    in API & Templates

    Posted

    Here's my version: 

    <?php

// Cache all topics
$template = $templates->get("topics");
$topics_children = $cache->get("all_topics", $template, function($pages) {
  return $pages->get("/topics/")->children();
});

//Topic1|Topic2
$search_topics = explode("|", $input->whitelist->topic);
//Get Topics from cache
foreach($topics_children as $topic) {
  $checked = (is_array($search_topics) && in_array($topic->title, $search_topics)) ? ' checked ' : '';
  echo "<label for='{$topic->title}'><input type='checkbox' name='topic[]' $checked value='{$topic->title}' id='{$topic->title}' /> {$topic->title}</label></br>"; 
}

//On my search template
if($input->get('topic')) {
  $value = $sanitizer->selectorValue($input->get('topic'));
  $selector .= "topics=$value, "; 					
  $input->whitelist('topic', $value); 
}
?>

    Thanks @Sergio but I don't think my problem is related to pagination, infact it works correctly on my side.
    I think it's rather something to do with whitelist on multiple checkbox (eg. forme_options[] ) which I cannot get it works. Also take a look at my url in my last post above: 

    
%5B%5D // I think it's [] encoded, but then it get lost on subsequent pages

    My bad, I misread it. 

    Maybe this will help you:

    [SOLVED] Lost query on search pages

    Here's how I did it on a similar project.

    The search query: https://www.brightline.org/resources/?keywords=distributed&resource_type=Reports&topic=Blockchain&author=Blockchain+Research+Institute&submit=1

    On the page: 

    if(count($resources) > 0) {
	$segment = '';
	if($input->urlSegment1) {
		$segment = $sanitizer->selectorValue($input->urlSegment1);
		$segment .= "/";
	}			
	echo $pagination = renderPagination($resources, $segment);
}

    And on a _func.php (or any other file like _init.php) 

    function renderPagination(PageArray $items, $segment = '') {

	if(!$items->getLimit() || $items->getTotal() <= $items->getLimit()) return '';

	$next = isset($options['next']) ? $options['next'] : __('Next');
	$previous = isset($options['previous']) ? $options['previous'] : __('Previous'); 

	$page = page();
	if(!$page->template->allowPageNum) {
		return "Pagination is not enabled for this template";
	}

	// customize the MarkupPagerNav to output
	$options = array(
		'numPageLinks' => 4, //4 is a good size for mobile as we're using next and prev items
		'nextItemLabel' => $next,
		'nextItemClass' => 'js-next',
		// 'previousItemLabel' => '<span><i class="uk-icon-angle-double-left"></i></span>',
		// 'previousItemClass' => '',
		// 'lastItemClass' => '',
		// 'currentItemClass' => 'tw-bg-orange tw-font-bold',
		'separatorItemLabel' => '<span>&hellip;</span>',
		'listMarkup' => "<ul id='js-pagination' class='tw-my-8 tw-justify-center tw-text-lg tw-list-reset tw-flex'>{out}</ul>",
		'itemMarkup' => "<li class='{class} tw-mr-3'>{out}</li>",
		'linkMarkup' => "<a href='{url}' class='tw-rounded tw-bg-white tw-px-3 tw-py-2 hover:tw-bg-orange hover:tw-text-white'>{out}</a>",
		'currentLinkMarkup' => "<span class='tw-px-2 tw-py-2'>{out}</span>"
	);

	


	$pager = modules('MarkupPagerNav');
	$pager->setBaseUrl($page->url.$segment);

	return $pager->render($items, $options);
}
