Selector. Where now between start date and end date or now bigger than start date and end date is emptyBy Elchin
I want select pages where now between date and end_date or now bigger than date and end_date is empty.
I have five tried variants:
$start = strtotime(date('Y-m-d') . " 00:00:00"); $results = $page->children("foo=(date<$start,date_end=''),bar=(date<$start,date_end>=$start),sort=-date,limit=12"); $start = strtotime(date('Y-m-d') . " 00:00:00"); $results = $page->children("date<$start,(date_end='',date_end>=$start),sort=-date,limit=12"); $start = strtotime(date('Y-m-d') . " 00:00:00"); $results = $page->children("date_end=''|date_end>=$start,date<$start,sort=-date,limit=12"); $start = strtotime(date('Y-m-d') . " 00:00:00"); $results = $page->children("!date_end|date_end>=$start,date<$start,sort=-date,limit=12"); $start = strtotime(date('Y-m-d') . " 00:00:00"); $results = $page->children("date_end>=$start|!date_end,date<$start,sort=-date,limit=12"); All this variants not worked for me and returned zero results.
I have a question that i can't find a way to solve.
I have following function in _uikit.php
$date = $page->get('date|createdStr'); $dateModified = $page->get('datemodified'); But I need to output the $date in to different formats.
My further function looks like this
// return the blog post article markup return " <div> <article class='uk-article blog-post $class'> <meta property='name' content='$page->title'> <meta property='author' typeof='Person' content='Arra Lifte Harmanschlag'> <meta property='dateModified' content='$dateModified'> <meta property='datePublished' content='$date'> <meta class='uk-margin-remove-adjacent' property='articleSection' content='News'> <div property='image' typeof='ImageObject'> $featuredBlogPostImage </div> $heading <ul class='mt25 uk-margin-remove-bottom uk-subnav uk-subnav-divider'> <li class='uk-article-meta'> <time datetime='$date'>$byline</time> </li> </ul> <div class='mt25' property='text'> $body </div> </article> </div> "; Now I need to output the meta property in this format 2019-03-02CET05:23:00 and then a normal date format that is displayed on the Homepage with 2. März 2019 without time.
Can anybody help me?
Thanks in advance.
Hey Ryan, hey friends,
we, Mobile Trooper a digital agency based in Germany, use ProcessWire for an Enterprise-grade Intranet publishing portal which is under heavy development for over 3 years now. Over the years not only the user base grew but also the platform in general. We introduced lots and lots of features thanks to ProcessWire's absurd flexibility. We came along many CMS (or CMFs for that matter) that don't even come close to ProcessWire. Closest we came across was Locomotive (Rails-based) and Pimcore (PHP based).
So this is not your typical ProcessWire installation in terms of size.
Currently we count:
140 Templates (Some have 1 page, some have >6000 pages)
~ 15k Users (For an intranet portal? That's heavy.)
~ 195 431 Pages (At least that's the current AUTOINCREMENT)
I think we came to a point where ProcessWire isn't as scalable anymore as it used to be. Our latest research measured over 20 seconds of load time (the time PHP spent scambling the HTML together). That's unacceptable unfortunately. We've implemented common performance strategies like:
We're running on fat machines (DB server has 32 gigs RAM, Prod Web server has 32gigs as well. Both are running on quadcores (xeons) hosted by Azure.
We have load balancing in place, but still, a single server needs up to 20 sec to respond to a single request averaging at around about 12 sec.
In our research we came across pages that sent over 1000 SQL queries with lots of JOINs. This is obviously needed because of PWs architecture (a field a table) but does this slow mySQL down much? For the start page we need to get somewhere around 60-80 pages, each page needs to be queried for ~12 fields to be displayed correctly, is this too much? There are many different fields involved like multiple Page-fields which hold tags, categories etc.
We installed Profiler Pro but it does not seem to show us the real bottleneck, it just says that everything is kinda slow and sums up to the grand total we mentioned above.
ProCache does not help us because every user is seeing something different, so we can cache some fragments but they usually measure at around 10ms. We can't spend time optimising if we can't expect an affordable benefit. Therefore we opted against ProCache and used our own module which generates these cache fragments lazily.
That speeds up the whole page rendering to ~7 sec, this is acceptable compared to 20sec but still ridiculously long.
Our page consists of mainly dynamic parts changing every 2-5 minutes. It's different across multiple users based on their location, language and other preferences.
We also have about 120 people working on the processwire backend the whole day concurrently.
What do you guys think?
Here are my questions, hopefully we can collect these in a wiki or something because I'm sure more and more people will hit that break sooner than they hoped they would:
- Should we opt for optimising the database? Since >2k per request is a lot even for a mysql server, webserver cpu is basically idling at that time.
- Do you think at this point it makes sense to use ProcessWire as a simple REST API?
- In your experience, what fieldtypes are expensive? Page? RepeaterMatrix?
- Ryan, what do you consider as the primary bottleneck of processwire?
- Is the amount of fields too much? Would it be better if we would try to reuse fields as much as possible?
- Is there an option to hook onto ProcessWires SQL builder? So we can write custom SQL for some selectors?
Thanks and lots of wishes,
Pascal from Mobile Trooper

I am trying to get the strftime format from the function convertDateFormat(). However, the output has $ signs in it which i cannot use in strftime.(example of conversion : $d/$m/%Y what strftime actually uses: %d/%m/%Y). Am I in the wrong here or is there some way to format strftime? Thank you in advance :).
I'm creating a multilingual blog for a client. I'm using Multi-language fields, and it's working great. Essentially, there are two versions of each article: one in English and one in Spanish.
Now, I've created a Datetime field with a "Date/time picker" so that they can add a publication date (no time) to their blog entries. I want the month part of the date to be displayed in whatever language the article is being displayed in. Let's take the following example:
1) "Un artículo de ejemplo", accessible via example.com/un-articulo-de-ejemplo/
2) "A sample article", accessible via example.com/en/a-sample-article/
In this example, for article number 1 I want the date to be "12 ene 2017", and for article number 2 I want it to be "12 jan 2017". In other words, the same format for both languages, but localised. And for some reason, I seem unable to do so and dates are always displayed in English.
Here's the code I'm using to display the date field:
<?= $post->publication_date; ?> How can I get this to work? Thanks.
