    I'm a beginner and was wondering why the code below isn't working. The issue is where ARTIST (capitalised) appears in the code for the second time. I want it to take the value from the first mention of ARTIST, but it's not doing anything. If I replace the second instance with the name of an artist, then it displays as expected. Hopefully I'm making a basic error! <!--Show artists that are related to current exhibition--> {% set ARTIST = page.exhibition_artist %} {% for artist in artist %} {{ artist.title }} <!--Show works that are related to current exhibition and belong to a given artist--> {% set work = pages.find("template=work, work_exhibition=[page.path], work_artist=[ARTIST]") %} {% for work in work %} {{ work.title }} {% endfor %} {% endfor %}

    Hi all, Currently I am working on a filter for all the products in a category. So I've set up a class and built a (PW) form in it. When the user clicks on continue the form should return a processform function which sets the variable of the form in a session. Later in the file I want to read out that session and use that variable to select which products should show up and which should be hidden. So now with code examples to make it a bit more clear for you: In my file I start with a class: class classname { public function ShowForm() { $form = $this->Form1(); if ($this->input->post->submit) { if ($this->processForm1($form)) $this->session->redirect("./"); } return $form->render(); } Then a form inside the class: protected function Form1() { $form = wire('modules')->get("InputfieldForm"); $form->description = "Fill in the fields to find the mouse which fits your wishes"; $form->label = "Mouse Selector"; $form->action = "./"; $form->method = 'post'; $f = wire('modules')->get("InputfieldRadios"); $f->name = "Hand"; $f->label = "label"; $f->addOption(1, "1"); $f->addOption(2, "2"); $form->add($f); $this->addSubmit($form, 'Continue'); return $form; } This function is called when the user submits: protected function ProcessForm1($form) { $form->processInput($this->input->post); $this->session->hand = (int)$form->get("Hand")->value; } As you see I store the variable of the submitted form in a session. After closing the class I continue with building the page and then I want to read out that variable: $value = $this->session->hand; $content .= "Value of 'Hand': " . $value; But when I execute this on my website I cannot see the value of the form. Have I done something wrong or how can I fix this? Thanks in advance, ~Harmen
  3. I extended my users-template with a lot af fields? One of them is 'instrument' The code beyond is working fine (see screenshot 1). 'instrument' is a page-select-field in the user template (the pages are violin, cello, clarinet, ...). But this is not nice and efficient coding!! // Violin $person = $users->find('instrument=violin'); echo "violin"; foreach ($person as $p) { // $user fields are shown echo $p->first_name; } // cello $person = $users->find('instrument=cello'); echo "cello"; foreach ($person as $p) { // $user fields are shown echo $p->first_name; } // clarinet $person = $users->find('instrument=clarinet'); echo "clarinet"; foreach ($person as $p) { // $user fields are shown echo $p->first_name; } // and so on With a foreach the code could me more efficient, but the find-selector givns a problem with the variable $instr. // all instrument in a foreach foreach ($user->instrument as $instr){ $person = $users->find('instrument=$instr'); // does not work, neither do find('$instr') and find($instr) echo $instr->title; foreach ($person as $p) { // $user fields are shown echo $p->first_name; } } With $person = $users-find($instr); only the value of $instr is shown (e.g. violin) but not the values of $p (e.g. first name of person. (see screenshot 2) How can I use a variable as find-selector?
  4. I’m trying to use the $template->name by declaring this in "_init.php": $cssFile = $template->name . ".css"; … and I then have this in "_main.php": // Use custom CSS-file if that file exists. <?php if(is_file($config->paths->templates . "styles/$cssFile")) { echo "<link rel='stylesheet' type='text/css' href='{$config->urls->templates}styles/$cssFile' />"; }; ?> However PW throws this notice: Notice: Undefined variable: template in /Users/claus/Sites/ProcessWire/site/templates/_init.php on line 29 Notice: Trying to get property of non-object in /Users/claus/Sites/ProcessWire/site/templates/_init.php on line 29 // Use custom CSS-file if that file exists. Do I have to define $template->name? I thought that was a built-in function?
  5. In the API section of PW website I found a comment made by Apeisa. He wrote: // If the page is editable, then output a link that takes us straight to the page edit screen: if($page->editable()) { echo "Edit"; } I'd like to use this function but the code shown above won't print a link - just a static string. How to edit this so the output would be a link leading to the exact page edit screen in admin control panel? Thanks. PS.
