Progress Update:

I'd like to drop debug mode in favor of a testing tab that I'm quite sure has been brought up before. The idea is to not have to throw your entire site in to JL debug mode just to test one thing in production. I've added this tab now, seems to work well.

Hi @Mike Rockett - just had a: PDOException: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'referrer' at row 1 #22001 in /var/www/html/site/assets/cache/FileCompiler/site/modules/ProcessJumplinks/ProcessJumplinks.module.php:534

because someone was trying to hack in with this link:


I'm not sure the best approach to preventing this exception - not sure if you should change the field type for the referrer column to support larger entries, or if you should just truncate the referrer if it's longer than allowed.

Collecting super long referrer values seems pointless (they're likely spam anyway), so truncating seems like a good approach. And the same applies to UA string as well 🙂


Edit: just checked a few log files, and I've got similar errors there... and some of these:

Exception: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'user_agent' at row 1 (in /site/modules/ProcessJumplinks/ProcessJumplinks.module.php line 534)

  • If I use the 404 monitor to fix a link the link should be removed from the 404 monitor so I do not fix it twice

@Mike Rockett has this been addressed yet? I have a customer complaining about this. Would be really nice if those 404 entries got removed. Any plans on implementing this? And thousand thanks for this great module!

@gebeer – Thanks 🙂 This hasn't been addressed in v1, as the plan was to carry the behaviour into v2 (sorry it's taken so long…) by way of the separate module. I picked up the project again recently and was giving it some thought. I might just include the 404 logger in JL v2, but am still 50/50 on it.

@teppo @adrian – You know, I should have truncated that alongside truncation of the request_uri. Going to see if I can squeeze this in over the weekend while I work on v2’s frontend.

Thanks for clarifying. Which hook would you use to trigger deletion of logger entries, ___executeEntity or ___executeCommit?

If you are using v1 of this module and you want to auto-remove entries from the 404 monitor when you create a jumplink from an entry there, you can use this simple hook in site/templates/admin.php

$this->addHookBefore('ProcessJumplinks::executeCommit', function(Hookevent $event){
    $input = $this->input->post;
    $sourcePath = $input->sourcePath;

    if($sourcePath) {
        $statement = "DELETE FROM process_jumplinks_nf WHERE request_uri = :sourcePath";
        try {
                'sourcePath' => $sourcePath
            $this->message("Eintrag '$sourcePath' wurde aus 404 Monitor Liste entfernt");
        } catch (\Throwable $th) {
            $this->error("Fehler beim Entfernen des Eintrags '$sourcePath' aus der 404- Monitor Liste: " . $th->getMessage());

and adapt the messages to your liking :-)

@a-ok Jumplinks 1 doesn't have built in support for automatically dealing with query strings. This is planned for Jumplinks 2, but I simply haven't had the time to complete it. For the time being, I'd be inclined to use the {all} wildcard on the end.

Source: chance-to-dance[/]{all}
Destination: somewhere/{all} or {!all} to skip wildcard cleaning

Hey @Mike Rockett, and sorry to bother you with this again, but just wanted to run something by you.

I've tried the solution above, but at least in my case it doesn't seem to be quite that simple. For some background, in this case the source path is "tilaukset" (orders in Finnish), and it should always link to a specific target URL. This works fine as-is, but when it's shared on Facebook, following the link from there results in 404 due to added query string.

Going step by step:

  1. If I append [/] to the end, it works with or without slash at the end — so far so good.
  2. If I also append {all} or {!all}, the redirect only seems to work if there's content there, i.e. plain "tilaukset" or "tilaukset/" no longer work.

I'm not sure if this is intentional or not, but I guess the question is if there's a way to specify that "I don't care what comes after this, it could contain nothing or it could contain content, either way ignore it"? 😄

I'm using <tilaukset|tilaukset?{all}> for now, but that seems pretty complicated when what I really want is (in terms of regex) "tilaukset.*" (or alternatively "tilaukset/?.*"). This also keeps the query string intact; I'd prefer it to be dropped, but that's not by any means a major issue.

Am I missing something?

FWIW, we needed to preserve query string parameters (mostly UTM params for campaign tracking) with a lot of permutations, and after trying a few different things, we ended up adding this bit to init.php. It seems to be working well for our particular use case.

	// Hook the 404 routine to catch valid URLs with UTM params.
	$this->addHookBefore('ProcessPageView::pageNotFound', function($event){	
		// Get the originally requested URL and its query string.
		// $_SERVER['QUERY_STRING'] is not reliable in this environment.
		$source_url = parse_url($_SERVER['REQUEST_URI']);
		$source_path = $source_url['path'];
		$source_querystring = $source_url['query'];	
		// Do nothing if there is no query string. Jumplinks can manage that.
		if(!isset($source_querystring)) return;

		// See if we have a jumplinks entry for the source path WITHOUT the query string.
		$db = wire('database');
		$source_string = trim($source_path, '/');
		$sql = "SELECT source, destination FROM process_jumplinks WHERE source = '".$source_string."/?'";
		$result = $db->query($sql);
		$match = $result->fetch(\PDO::FETCH_ASSOC);
		// If any matches are found, try redirecting to it, appending the original query string.
		$target = $match['destination'];
		if($target != ''){
			// is this a path or a page ID?
			if((strpos($target, 'page:') !== false)){
				$id = (int) ltrim($target, 'page:');
				$page = wire('pages')->get($id);
				$target_url = $page->url.'?'.$source_querystring;
				$target_url = '/'.str_replace('{!all}','',$target);
				$target_url .= '?'.$source_querystring;

			// wire('log')->save('querystrings', 'Source: '.$source_path.', Target: '.$target_url);		

Maybe others will find it helpful.

@teppo @Jason Huck – In JL1, this unfortunately requires two jumplinks – one for including the query string, and the other for excluding it. I know, it really sucks, but JL2 solves this problem by using optional parameters and a little bit of internal trickery. I do still need to add in a boolean flag on jumplinks to indicate whether or not they should even care about the query string. I would prefer to not implement this flag, but sometimes it's useful when you don't care about it so much that you'd rather not even make mention of it in the source.

Hi Folks
I wonder if I could strip with Jumplinks from certain URL's like
just the last part #prodDescription. Could also be a general thing, that whenever this #prodDescription appears, it would be removed.
The client uses those links into a tab on an other System, which means there would several hundert links to be changed.

Your help is much appreciated!

I'm pretty sure those anchor hashes never reach the server and are evaluated by the browser only.

sorry you're right they got to the browser as %23prodDescription. So we would need to strip %23prodDescription this.

I think what I meant to say was that the hash (#prodDescription) is never sent to the server. ProcessWore doesn't know about it. Any redirects that are dependent on the presence or absence of a hash need to be done in JavaScript on the client.

when you call the page with those # it opens the correct page. The Problem is, that they copied all those links with the # and use them in the CRM. So when they generate Quotes the link to this pages form a generated PDF Quote. Therefor it would be helpful if we could remove this particular part %23prodDescription of the url, then the Link would work perfectly. Else you just get an 404.

@bbeer – if you are getting URLs with the encoded %23, then I think that htaccess would be your best bet until JL2 is ready (working on it as I write this). It must be that the CRM is encoding the hash when storing the URL (bad move, CRM), which the browser then sends to the server, which sees it as part of the actual URI. The browser will never send it if it is not encoded. 

If htaccess is too messy, then you could perhaps append the source with {all}, which would catch everything after the last 'segment' – the destination could then just ignore this. Not the best solution I know, but seems like it could work for the time being…

I just installed the ProcessJumplinks module. I am trying to have one of my existing pages redirect to a separate url.

I would like to have visitors to https://www.johnsonville.org/recipes/ be redirected to https://www.johnsonville.org/docs/!recipes/doku.php

Here's what I've set as a jumplink:

Source: recipes/
Destination: https://johnsonville.org/docs/!recipes/doku.php

I'm not seeing any redirection... is this something that can be accomplished with ProcessJumplinks?

Jumplinks is only designed to kick in when a URL 404s.

Your best bet is you place the redirect in the template file that is used to display the /recipes/ page, eg:

Line 785 of ProcessJumplinks.module results in unexpected behaviour:

$this->session->redirect($convertedWildcards, !($starts || $ends));

As soon as the start time of a jumplink is set (after the first hit), the redirect wil be 302 (temporary) even if the end date is empty/not set.
I think only redirects with an end date should be temporary (302), otherwise permanent (301).

New Maintainer Needed

Jumplinks is in need of a new maintainer, as I’m simply unable to commit to continued development. As it is, Jumplinks v2 has been in the pipeline for around four years now. Whilst v1 is stable (after so long, excluding a few minor issues here and there), there are features that people would like in v2 that are not in v1, and so the idea is that a capable maintainer takes over and breathes some life back into the project as I'm unable to due to work commitments.

Current state of v2: backend is mostly functional, and the frontend was being re-written in Svelte (though whomever takes over is free to change this) after having been partially done in jQuery (I no longer use it for anything). As discussed previously, the backend side of things is powered by some Illuminate (Laravel) components, making it easier to interact with the DB and perform tasks on different models. Again, whomever takes over the project is free to change this, or even start from scratch if necessary.

If you are reading this message and are interested in taking over the development of Jumplinks, please pop me a private message and we can take it from there.

Thanks all! 🙂

Hi @Mike Rockett

Are JumpLinks to external sites generating 301 redirects?
I need to redirect most of the content of a site to an eternal site and unsure if I should use JumpLinks or a HT access 301 redirect.
Many thanks

      (once again I was surprised to see a work of mine pop up in the newsletter, this time without even listing the module on PW modules website 😅. Thx @teppo !)
      Github: https://github.com/romaincazier/FieldtypeQRCode
      Modules directory: https://processwire.com/modules/fieldtype-qrcode/
      This is a simple module I made so a client could quickly grab a QR Code of the page's url in the admin.
      There's not much to it for now, but if need be you can output anything using a hook:
      $wire->addHookAfter("FieldtypeQRCode::getQRText", function($event) { $event->return = "Your custom text"; }) You can also output the QR code on your front-end by calling the field:
      echo $page->qr_code_field; The module uses the PHP library QR Code Generator by Kazuhiko Arase. When looking for a way to generate a QR Code in PW I came across @ryan's integration in his TFA module. I'm not very familiar with fieldtype/inputfield module development so I blindly followed @bernhard (great) tutorial and his BaseFieldtypeRuntime. At some point I'll take a deeper look to make a module on my own.
      Some ideas for improvements :
      add the ability to choose what to ouput : page's url / editUrl / file(s) / image(s) / ... allow to output multiple QR codes ?

      Inspired by @bernhard's excellent work on the new customisable LESS CSS getting rolled into the core soon, I thought I would offer up the module for beta testing, if it is of interest to anyone.

      It takes a different approach to admin styling, basically using the Cascade part of CSS to over-ride default UiKit values.
      Values are stored in ModuleConfig Module creates a separate AdminThemeTweaker Folder at root, so it can link to AdminThemeTweaker.php as CSS AdminThemeTweaker.php reads the module values, constructs the CSS variables then includes the CSS framework Can be switched on and off with a click. Uninstall removes everything, thanks to bernhard's wonderful remove dir & contents function.
      It won't touch your core. It won't care if stuff is upgraded. You won't need to compile anything and you don't need to touch CSS unless you want to.

      It won't do much at all apart from read some values from your module config, work out the right CSS variables to use (auto contrast based on selected backgrounds) and throw it on your screen.
      You can configure a lot of stuff, leave it as it comes (dark and curvy), change two main colors (background and content background) or delve deep to configure custom margins, height of mastheads, and all manner of silly stuff I never use.

      Have been developing it for somewhere around 2 years now. It has been (and will continue to be) constantly tweaked over that time, as I click on something and find something else to do.
      That said, it is pretty solid and has been in constant use as my sole Admin styling option for all of those 2 years.

      If nothing else, it would be great if it can provide any assistance to @bernhard or other contributor's who may be looking to solve some of the quirkier UiKit behavior.
      Has (in my opinion) more robust and predictable handling of hidden Inputfields, data-colwidths and showIf wrappers.
      I am very keen to help out with that stuff in any way I can, though LESS (and any css frameworks/tools basically) are not my go.
      I love CSS variables and banging-rocks-together, no-dependency CSS you can write with notepad.

      I see old posts saying that repeaters are not the way to go in Custom Process Modules. If that is the case, when using forms (as I am trying to do) how would one tackle things like repeat contact fields where there can be multiple requirements for contact details with different parameters? (Like point of contact, director, etc) or even telephone numbers that have different uses?
      Just for background I am creating a process module that allows me to create types of financial applications in the admin area (no need to publish any of this, pure admin) that require a lot of personal or company information.
      Maybe I am thinking about this incorrectly?

      PageViewStatistic for ProcessWire is a module to log page visits of the CMS. The records including some basic information like IP-address, browser, operating system, requested page and originate page. Please note that this module doesn't claim to be the best or most accurate.
      One of the biggest advantage is that this module doesn't require any external service like Google Analytics or similar. You don't have to modify your templates either. There is also no Javascript or image required.
      There is only one disadvantage. This module doesn't record visits if the browser loads the page from its browser cache. To prevent the browser from loading the page from its cache, add the following meta tags to the header of your page:
      <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> How to use
      The records can be accessed via the Setup-menu of the CMS backend. The first dropdown control changes the view mode.

      Detailed records
      View mode "Detailed records" shows all visits of the selected day individually with IP-address, browser, operating system, requested page and originate page. Click the update button to see new added records.

      Cached visitor records
      View modes other than "Detailed records" are cached visitor counts which will be collected on a daily basis from the detailed records. This procedure ensures a faster display even with a large number of data records. Another advantage is that the detailed records can be deleted while the cache remains. The cache can be updated manually or automatically in a specified time period. Multiple visits from the same IP address on the same day are counted as a single visitor.

      Upgrade from older versions
      Cached visitor counts is new in version 1.0.8. If you just upgraded from an older version you might expire a delay or even an error 500 if you display cached visitor counts. The reason for this is that the cache has to be created from the records. This can take longer if your database contains many records. Sometimes it might hit the maximally execution time. Don't worry about that and keep reloading the page until the cache is completely created.
      Special Feature
      PageViewStatistic for ProcessWire can record the time a visitor viewed the page. This feature is deactivated by default. To activate open the module configuration page and activate "Record view time". If activated you will find a new column "S." in the records which means the time of view in seconds. With every page request, a Javascript code is inserted directly after the <body> tag. Every time the visitor switches to another tab or closes the tab, this script reports the number of seconds the tab was visible. The initial page request is recorded only as a hyphen (-).

      You can access the module settings by clicking the Configuration button at the bottom of the records page. The settings page is also available in the menu: Modules->Configure->ProcessPageViewStat.
      This module uses the IP2Location database from: http://www.ip2location.com. This database is required to obtain the country from the IP address. IP2Location updates this database at the begin of every month. The settings of ProcessPageViewStat offers the ability to automatically download the database monthly. Please note, that automatically download will not work if your webspace doesn't allow allow_url_fopen.
      This module uses DragScroll. A JavaScript available from: http://github.com/asvd/dragscroll. Dragscroll adds the ability in view mode "Day" to drag the records horizontally with the mouse pointer.
      This module uses the PHP class parseUserAgentStringClass available from: http://www.toms-world.org/blog/parseuseragentstring/. This class is required to filter out the browser type and operating system from the server request.
