Not helpful error messages

Recommended Posts


I have received many emails with same error message and I am wandering how to change the code to get more meaningful errors. Hope someone know what could to be the reason for that exception or how to render more details in that exception. Аny help is greatly appreciated. Below is the error:

Unknown User:/?/:ProcessWire Error:Exception:

You are right that's a terrible error message! :rolleyes: But, you shouldn't get this error message if you are running the latest PW. The latest PW will give you a better error message. However, I'm familiar with this particular error and it means that the database connection failed. Your database server was down or overloaded and PW couldn't connect to it. Since Modules are the first thing it tries to load, that query failed.

      I was hoping to be able to do this entirely in PHP but was having all kind of issues getting it to see my values as numbers instead of strings (got error messages because my PW debugging is currently set to true). I currently have about 10 cards that PW is generating that include thumbnails, descriptions, donation amounts (raised amounts and goal amounts), and donate buttons. What I was trying to do was take the goal amount divide it by the raised amount (using PHP) and simply insert that value into the Progress element's Value attribute. Sounded simple enough but I couldn't get PHP to simply divide those two fields. First I tried dividing the goal value by the raised value and inserting it into the value attribute, like so:
      <? php $raised = $page->get("raisedAmount$count"); $goal = $page->get("goalAmount$count"); $percent = $goalNum / $raisedNum; ?> <progress value="<?php echo $percent; ?>" max="100"></progress> Which gave me this error message:
      Uncaught TypeError: Unsupported operand types: string / string
      Then I tried converting the two strings to integers because apparently PHP couldn't detect they were numbers and do it, like so:
      <?php $raised = $page->get("raisedAmount$count"); $goal = $page->get("goalAmount$count"); $goalNum = (int) $goal; $raisedNum = (int) $raised; if ($raisedNum != 0) : $percent = $goalNum / $raisedNum; else: $percent = 0; endif; ?> <progress value="<?php echo $percent; ?>" max="100"></progress> but all of the progress bars remain at zero percent (not shown), even when I have values in some of the $raised variables.
      Please note, if I add this code:
      <?php echo $percent; ?> below the Progress element, it shows 0 on every single card, so the $percent is never calculated (as per the $percent = $goalNum / $raisedNum;) even though $raisedNum should not equal 0 during that iteration of the loop (the original code includes a loop, which I omitted to keep the code sections above smaller, notice the $count at the end of the $raised and $goal variable declarations). When the loop goes over "raisedAmount1" there is a value in there; however, after typecasting it to an integer ($raisedNum) the value is 0 for someodd reason instead of 40,000, which is what is in the $raisedAmount1 field in Processwire...
      I'm new to relatively new to PHP and Processwire and could really use some help on this one. Thanks in advance for any helpful replies!

      I have a nested page structure that fails for users without superuser permissions:
      Works for superusers / non-superusers:
          - foo
          -- bar
          --- page (status: published)
          ---- page (status: published)
          --- page (status: published)
      Fails for non-superusers (Works for superusers):
          - foo
          -- bar
          --- page (status: published)
          ---- page (status: published)
          --- page (status: unpublished <- apparently the template structure fails when there's one unpublished page)
      <?php foreach ($page->children('include=all') as $p): #Fails for non-superusers ?> <?=$p->render()?> <?php endforeach; ?>     a) Works for non-superusers when I grant Page Edit permissions (on the template) to their assigned role/s.
          b) When I remove 'include=all' or 'include=unpublished' then it also works for non-superusers:
      <?php foreach ($page->children() as $p): #Works for non-superusers ?> <?=$p->render()?> <?php endforeach; ?> Error message (non-superusers)

      Chäs & Co is a b2b cheese trader. They love good cheese and are proud of their excellent knowledge und connections to small cheese producers. They maintain a custom made database and used to copy/paste (!) the cheese infos to the former CMS (Contao). Since substituting the database with ProcessWire was no option, they export now the database to a csv file and import it to the new website (expanded version of module ImportPagesCSV).
      From there, the pw magic begins. The staff works with the admin interface: They search and find products in notime using the build-in search field (using cheese names or id. Using ids only possible by adding hook, see this forum thread). They generate price lists easily based on a template, providing checkboxes and option buttons for some restrictions, choose i.e. the cheese origin and price audience (all implemented as page selectors). By saving the page a PDF list gets generated (using mpdf, a php pdf library).
      The visitors can sort and filter the products using a form by shuffle.js. Product details are shown in a popup (fancybox). There's also the option for generating a nice pdf data sheet. No CSS framework being used.
      Other modules used: ProcessJumpLinks, ProcessProMailer, ProcessWireUpgrade.

      Hey all. I'm having an issue with the new custom page classes feature which is a fantastic tool.
      I am running into a recursion issue when attempting to call a custom page class. I have a class called BlogPostPage.php (for blog-post.php) which contains a method called getSummary(). That method gets a summary field or truncates the body in it's absence. I've attached photos of the template code, custom page class code (which I've simplified for testing), and the PW output error.
      There is no recursion in the getSummary() method. This error occurs whether I output multiple blog posts in a loop or if I output one blog post with no looping in my template code.

      In use:
      ProcessWire 3.0.164 dev
      PHP 7.3.13

      I am also using the Template Engine Twig module which has not caused any errors or issues thus far.
      Many thanks!

      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.
      The user can enter one or more opening times per day in a UI.
      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
