  1. Hello so am trying to make a hook so that all checkbox field is defaul;ty checked when making new page, soo i made hook in init.php and the contents are <?php $wire->addHookAfter("Pages::added", function($event) { $page = $event->arguments(0); // check for page template if necessary here $page->checkboxfield('check', 1); }); ?> and what i get which is weird because "table" is a repeat field where checkboxfield is nowhere present, but table repeat field and checkboxfield are in the same template, so why does it outputs error like that? any ideas ?
  2. Hi folks, i try to use a hook to change some markup inside admin, this hook works fine inside a ready.php file, but its not working inside my module: <?php namespace ProcessWire; class InputfieldPageTableExtendedGrid extends InputfieldPageTable { public static function getModuleInfo() { return array( 'title' => __('Inputfield for PageTableExtendedGrid', __FILE__), // Module Title 'summary' => __('Adds Inputfield for PageTableExtendedGrid', __FILE__), // Module Summary 'version' => 233, 'requires' => array('FieldtypePageTableExtendedGrid'), 'permanent' => false, ); } public function ready() { $this->addHookAfter('Page::render', function($event) { $value = $event->return; // Return Content $style = "<style type='text/css'>". $this->pages->get((int) wire('input')->get('id'))->style ."</style>"; // Add Style inside bottom head $event->return = str_replace("</head>", "\n\t$style</head>", $value); // Return All Changes }); } } whats wrong here?
  3. Hello Till now I hacked something with the twig template but it works no more with new PW versions so I look forward to create a module. I am working on a site in multiple languages : French, English, Italian, German, Spanish, Portuguese, Hebrew, Russian. The new posts are entered in any language with a field for language. Till now, I got twig files to get the translations with constants defined for each part of the pages. So I'd like to create a module to include theses files added according to the url /fr/en/... Have you some observations to do before I begin about the direction to take ? Thank you
  4. Hello, I have a hook in a custom method of a non autoload module and it is not calling my hook method. In the wiki I read Modules that are intended to attach hooks in the application typically should be autoload because they listen in to classes rather than have classes call upon them. If they weren't autoload, then they might never get to attach their hooks. Does this mean that hooks are only working in autoload modules? I added 'singular' => true and 'autoload' => true to getModuleInfo() but still my hook funktion does not get called. My hook call at the end of this render method $this->inlineScript = $inlineScript; $page->addHookAfter('render', $this, 'addInlineScript'); $page object is available. Also tried $this->addHookAfter('Page::render', $this, 'addInlineScript'); and my hook method public function addInlineScript($event) { exit("gbr"); // $value contains the full rendered markup of a $page $value = $event->return; $value = str_replace("</body>", $this->inlineScript . "</body>", $value); // set the modified value back to the return value $event->return = $value; } Why is this not working? Any help would be much appreciated.
  5. Hello all, wasn't sure where to put this, so it goes in General section. Ryan shows a hook that we can use to mirror files on demand from live server to development environment to be up to date with the files on the server without having to download complete site/assets/files folder. I just implemented this but had problems getting files to load from a site in development that is secured with user/password via htaccess. First I tried to use WireHttp setHeader method for basic authentication like this function mirrorFilesfromLiveServer(HookEvent $event) { $config = $event->wire('config'); $file = $event->return; if ($event->method == 'url') { // convert url to disk path $file = $config->paths->root . substr($file, strlen($config->urls->root)); } if (!file_exists($file)) { // download file from source if it doesn't exist here $src = 'http://mydomain.com/site/assets/files/'; $url = str_replace($config->paths->files, $src, $file); $http = new WireHttp(); // basic authentication $u = 'myuser'; $pw = 'mypassword'; $http->setHeader('Authorization: Basic', base64_encode("$u:$pw")); $http->download($url, $file); } } But, unfortunately this didn't work. So now I am using curl to do the download. My hook function now looks like this function mirrorFilesfromLiveServer(HookEvent $event) { $config = $event->wire('config'); $file = $event->return; if ($event->method == 'url') { // convert url to disk path $file = $config->paths->root . substr($file, strlen($config->urls->root)); } if (!file_exists($file)) { // download file from source if it doesn't exist here $src = 'http://mydomain.com/site/assets/files/'; $fp = fopen($file, 'w+'); // init file pointer $url = str_replace($config->paths->files, $src, $file); $u = 'myuser'; $pw = 'mypassword'; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_TIMEOUT, 50); // crazy high timeout just in case there are very large files curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERPWD, "$u:$pw"); // authentication curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); // authentication curl_setopt($ch, CURLOPT_FILE, $fp); // give curl the file pointer so that it can write to it curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); $data = curl_exec($ch); curl_close($ch); } } Now I can load files and images from the htaccess protected development server 🙂 If anyone knows how to get this to work with WireHttp, please let me know. Thank you.
  6. I'm trying to update certain repeater fields with a hook. This almost works, but is somehow buggy. Each repeater is supposed to represent a row: service, remarks, number of days, day-rate, row total. The last repeater should then show the grand total. I've tried this: $this->addHookAfter("Pages::saveReady", function (HookEvent $event) { $page = $event->object->getPage(); if ($page->template->id == 89 && $page->parent->parent->id == 11180) { $repeater = $page->offer_calc_repeater; $itemCount = $repeater->count(); $c = 0; $grandTotal = 0; foreach ($repeater as $rep) { if($c < ($itemCount - 1) ) { if (!empty($rep->days) && !empty($rep->daily_rate)) { $num_days = $rep->days; $day_rate = $rep->daily_rate; $row_total = $num_days * $day_rate; $rep->row_total = $row_total; $grandTotal = $grandTotal + $row_total; $page->save(); unset($num_days); unset($day_rate); unset($row_total); $c++; } } if ($c == $itemCount) { $rep->row_total = $grandTotal; } } } }); Most calculations are correct, but: The first one is empty. The second one is calculated wrong. I've tried typecasting (float), or checking with strlen instead of !empty, but that doesn't make any difference. Is the Pages::saveReady the ideal hook for such stuff? (placed in site/ready.php). Also, I get an error message: Session: Method Pages::getPage does not exist or is not callable in this context. Any ideas? Would you perhaps rather do stuff like this via JS?
  7. Hello! The only hook into 'trash' in a module runs twice, by itself, as it seems. The following code outputs: Session: Hooked 1 times on abcd Session: Hooked 2 times on abcd on the admin side when one page is deleted from it's delete tab. And it's no matter 'addHookBefore', 'addHookaAfter' or 'addHook' method is used. Why?! private $i = 0; public function init() { $this->pages->addHookBefore('trash', $this, 'test'); } public function test($event) { $page = $event->arguments('page'); $this->i++; $this->message("Hooked {$this->i} times on {$page->title}"); }
  8. I've created a simple sports league fixture generator in a template called 'League'. Teams are added as page references then a fixture list is created as a ProFields table by hooking page save to add new rows to the table. The bit I need help with is that I'm trying to check a fixture doesn't already exist before adding it to the table (e.g. if a new team is added to the league). I'm trying to do this with a PW selector to filter the fixtures table and check whether Team A vs Team B already exists in the table. Then on the next line checking no fixture was found by using count(). However as soon as I add the selector the script no longer adds any rows to the table. If I take it out, it all works fine (albeit with duplicate fixtures each time the page is saved). I've also tested the selector in a page template and it filters as expected. It's late here (UK)... I'm probably doing something stupid! Any ideas? <?php //Hook page save to generate league fixture lists $wire->addHookAfter("Pages::saved(template=league)", function ($event) { //Get which page has been saved $page = $event->arguments(0); $noFixturesAdded = 0; //For each team in league cycle through and add home fixtures foreach ($page->teams_in_league as $teamA) { foreach ($page->teams_in_league as $teamB) { //Check if fixture already exists $existingFixtures = $page->fixtures("team_a=$teamA,team_b=$teamB"); //Check team A is not the same as team B as you can't play yourself //Then add row to fixture table if ($teamB != $teamA && $existingFixtures->count() < 1 ) { $fixture = $page->fixtures->makeBlankItem(); $fixture->team_a = $teamA->id; $fixture->team_b = $teamB->id; $page->fixtures->add($fixture); $noFixturesAdded ++; } } } //Save updates to table $page->save('fixtures'); $message = "League saved. $noFixturesAdded new fixtures were added"; $this->message($message); });
  9. It's a bilingual site. There are two pages: "Artists" and "Events" each with a "Page Reference" field connecting each other. - Artists has a field where one can choose events available. - Events has a field where you can either choose artists available or create new ones. The problems: - When I create an "Artist" page and select events from the list, it doesn't update the collection of participating artists on the "Event" page. - When I create an artist from the "Event" page. The field 'artist page > settings > language' is not "Active" for the second language. When the artist page is created manually,"Active" is on by default. I know this all have to do with hooks, but I'm don't fully understand the logics.
  10. Hello forum! I started to write my first hook for Processwire but I'm pretty confused how you should write these. My idea is to hook after publishing in init.php (called before templates) for a certain template. Here's the code: Trying to reset the checkbox (ajasta) and then saving it so it shows unchecked in the admin page when publishing "article" page. But the code isn't doing anything. Not even dumping anything What seems to be the problem? And have you made a similar hook for this usage or am I doing it totally wrong? 😄 Thanks for the support in advance!
  11. In a project I had to add the attribute 'disable' to some options of a select field (page reference) to show them but make them unselectable. Since I could not find an integrated solution, I wrote a tiny module and a hook. This could also be a POC to similar needs. Install module Add the Module to InputfieldPage in the module settings to make it selectable as Inputfield for page reference fields Create a hook in ready.php to manipulate attributes of the <option> tag for specified items Module <?php namespace ProcessWire; /** * POC Inputfield Select Hook Add Option -- Replacement for InputfieldSelect * * Selection of a single value from a select pulldown. Same like InputfieldSelect * except this version provides hookable addOption() function which allows to modify * attributes of the <option> tag (i. e.

Same like InputfieldSelect. except this version provides hookable addOption() function which allows to modify attributes of the <option> tag (e.g. \'disabled\' to show items in dropdown but disallow to select', __FILE__), // Module Summary 'version' => 100, ); } /** * Hook in here to modify attributes */ public function ___addOptionAttributes($value, $label) { return array(); } /** * @see InputfieldSelect::addOption() * */ public function addOption($value, $label = null, array $attributes = null) { if (!is_array($attributes)) $attributes = array(); $attributes = array_merge($attributes, $this->addOptionAttributes($value, $label)); return parent::addOption($value, $label, $attributes); } } Hook /** * This example hook modifies the attributes of the selectable options of a Pagereference field named 'test'. * The selectable pages have the template 'test' assigned which includes a checkbox 'disallow'. * The attribute 'disabled' will be added to the selectable page if the user does not have the role 'user-extended' and 'disallow' is set. * */ $wire->addHookAfter('InputfieldSelectHookAddOption::addOptionAttributes', function($e) { // quick exit if ($e->object->name != 'test') return; if ($this->wire('user')->isSuperuser()|| $this->wire('user')->hasRole('user-extended')) return; // disable items (pages) in select $restrictedPageIDs = $this->wire('pages')->find('template=test,disallow=1')->each('id'); if (in_array($e->arguments[0], $restrictedPageIDs)) $e->return = array('disabled' => 'disabled'); });
  12. Hello, I am getting nuts trying to understand hooks and I hope someone in the community will be able to help. This is deiving me crazy ! I have tested tens of possibilities to eventually reduce my code to this : bd('outside'); $wire->addHookAfter('Page::render', function($event) { bd('inside'); }); And if someone could tell me why my bd('inside'); never triggers... I would be infinitely grateful ! EDIT : Forgot to say : this piece of code is in my _init.php included in my template (but I've also tried in my site/ready.php for no better results...)
  13. Is there a hook to do something right after cloning a page ? I want the page to be saved right after cloning it either from the button in the tree or from a lister, because saving the page triggers several calculations that are not triggered by just cloning the page. Thanks in advance !
  14. Hi! tell me, pls, how to execute this equality (from ready.php) $wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) { if($event->object->hasField == 'FIELDNAME') { ..... } } - $hasField The Field object associated with this Inputfield (from definition parent class for InputfieldPage) the left side equation is the object entity, and the right side - the string How it is?
  15. Hey, I want to hook into the 404 handling of PW at the most earliest stage. Pleas can anybody point me to the hook or file that suits this best?
  16. Hi, I have a page with a repeater called teams with two fields: team (a pageReference with a list of teams) and people (a pageReference with a list of people who likes this team). I'm trying to populate the people field in the repeater according to the value of the team field in the same repeater. So far. I'm able to get the pageArray that I want to assign to the people field, but i don't know how to "save" the value for each instance of the repeater. I hope somebody can give me a light. Thanks in advance. $wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) { if($event->object->hasField == 'people') { $repeaterField = $event->arguments('page')->teams; foreach ($repeaterField as $t) { // Is this the way to loop the instances of the repeater? $team = $t->team->id; $t->people = $event->pages->find("template=user, team={$team}"); var_dump($t->people); // This returns the values that i want to assign for each repeate instance $event->return = $t->people; // I hope this assign a custom pageArray for each repeater, but it assigns the same for all the instances of the repeater } } });
  17. Hello, I am not that experienced with hooks and was hoping if somebody could me with this task: I have a InputfieldFile in wich a single generated file will be added after checking a checkbox in the back-end and saving the page. This happens in the saveReady-hook of a page with a specific template inside a ready.php: <?php $this->addHookAfter("Pages::saveReady", function($event) { $page = $event->arguments(0); if ($page->template->name === "example") { if ($page->checkboxField) { $page->fileField->add($generatedFile); } } }); Now if a new file should be generated and there is already a file in this InputfieldFile, I would like to remove the previous file and replace it with the new one: <?php if (count($page->fileField)) { $page->fileField->removeAll(); } That works well so far. My problem is, that I want to add the new file with the same name filename.pdf. But when I remove the previous file and add the new file inside the same saveReady-hook, the previous file still exists until the page is saved and the name of the new file will be added a filename-1.pdf, because ProcessWire makes the filename unique when a file with the same name exists. My question is: Is there a hook or way to remove the previous file before the new file will be added to keep the same filename? I tried to unlink the previous file, but then the InputfieldFile doesn't always gets updated correctly and has one empty file and the new file. 😉 Regards, Andreas
  18. Hello! I apologize in advance if I missed something on the forums. I'm not yet that experienced with hooks and already tried a lot. Maybe someone else has an idea or could give me a hint in the right direction. In my ready.php file I'm creating a random generated URL slug on Pages::setupNew for a specific template. When creating a page and I type in the default language title and leave the other languages blank, the slug gets appended to the page names because the pages have the same url/slug/title but in different trees ( ex. /myarticle-myslug/ and /en/myarticle-myslug/ ) When creating a page and I enter a title for each language, the slug gets only applied to the default language and I get an error that the name for the default language already exists and it was changed to /myarticle-myslug/. The other language gets the page name /en/my-article/ applied. Additionally I noticed that the settings from Module -> Page Name (InputfieldPageName) are not applied when creating the page name using the code below. So non-ascii characters get stripped instead of sanitized Here is a simplified code snippet that I have in the ready.php file: wire()->addHookBefore('Pages::setupNew', function($event) { $page = $event->arguments('page'); if ($page->template->name == 'news-article') { $page->name = $page->title . '-myslug'; } }); I've read this topic and if this still applies, LanguageSupportPageNames isn't used on Pages::setupNew. Especially the post by @Soma looks interesting but I'm not sure how to apply it. Thank you very much in advance.
  19. Hello, I still did not solve my problem about Hebrew letters. In fact, it is ok for Russian for example to have a transliteration of characters (one to one) but in languages like Hebrew, Arabic, it is better to slugify with phonetic like here : use EasySlugger\Utf8Slugger; $slug = Utf8Slugger::slugify('日本語'); // slug = ri-ben-yu $slug = Utf8Slugger::slugify('العَرَبِيةُ‎‎'); // slug = alrbyt $slug = Utf8Slugger::slugify('עברית'); // slug = bryt So I am planning to insert https://github.com/javiereguiluz/EasySlugger Should I create a module or just add a hook ? I am a PW newbie. Thanks for your help
  20. $this->addHookBefore('InputfieldTextarea::render', function($event) { $field = $event->object; if($field->name == 'body_offer') { $del = ''; foreach($this->wire->pages->get(11229)->textblocks as $item) { $field->entityEncodeText = false; $body = str_replace(PHP_EOL, '', $item->body); $body = addslashes($body); $title = $item->title; $field->description .= $del . "<a href=\"#\" class=\"ckesnippet\" data-snippet=\"$body\">$title</a>"; $del = ' | '; } } $js = wire('config')->urls->templates . 'scripts/ckesnippets.js'; $event->return = str_replace("</html>", "\n<script type='text/javascript' src='$js'></script>\n</html>", $event->return); }); I'm trying to add custom text-blocks from repeater fields into CKEditor. I've stolen the whole idea (and code) from @bernhard Problem is: The links are actually being rendered, but the Javascript is not loaded, i.e. the $event->return line doesn't seem to work. If I inspect the HTML, my additional script-tag is nowhere to be seen. I don't get any errors either. Running latest PW dev + PHP 7.1.19.
  21. I use a PageTable field to make edits to children of pages more intuitive… To register the hooks, insert the following Snippet inside your init function in your module (or add it to your init.php file): /** * Initialize the module. * * ProcessWire calls this when the module is loaded. For 'autoload' modules, this will be called * when ProcessWire's API is ready. As a result, this is a good place to attach hooks. */ public function init() { // Prefill pageTable field $this->wire()->addHookBefore('InputfieldPageTable::render', $this, 'addChildrenToPageTableFieldsHook'); $this->wire()->addHookBefore('InputfieldPageTableAjax::checkAjax', $this, 'addChildrenToPageTableFieldsHook'); } Then, add this hook method: /** * Fill pagetable fields with children before editing…. * * @param HookEvent $event */ public function addChildrenToPageTableFieldsHook(HookEvent $event) { $field = $event->object; // on ajax, the first hook has no fieldname if (!$field->name) { return; } // get the edited backend page $editID = $this->wire('input')->get->int('id'); if (!$editID && $this->wire('process') instanceof WirePageEditor) { $editID = $this->wire('process')->getPage()->id; } $page = wire('pages')->get($editID); // disable output formating – without this, the ajax request will not populate the field $page->of(false); // you could also insert a check to only do this with sepcific field names… // $page->set($field->name, $page->children('template=DesiredTemplate')); // just specific templates $page->set($field->name, $page->children); } Now whenever there is a page-table field on your page, it gets populated with the children
  22. Hi, Thank you for the wonderful CMF. This is my first question to the PW community as I started with it. I am in the process of trying to create a module. The basic need is I want to change the content of the 404 page, if the route is something special. Eg : say the request is for http://processwire.localhost/hello and if I know the path doesn't exists I want to do something special. public function init() { $this->addHookBefore('ProcessController::execute', $this, 'someMethod'); } public function someMethod($event) { // also how do I access the $_SERVER variables from processwire point of view } Also how do I access the $_SERVER variables from a PW context. Something like $pages->get('SERVER').
  23. Hello @ all, today I am struggeling with the deletion of empty repeater items after saving in the backend. Explaination: Imagine you are adding an additional repeater item in your form in a page via the "Add button". Then you forget to fill out this item so it is empty. After submitting the form the empty repeater item is still there because you did not deleted it with the basket symbol (deletion) Goal: In theory it must be possible to create a hook that checks the repeater items for content and delete the empty items after saving. At the moment I dont know how to check if an item is empty or not. I know how to delete fields in the repeater item but not the complete item itself. Can anyone point me into the right direction? Best regards
  24. I have a hook to change the template file on a certain page. This is not working at the moment for some reason. The usual location to place templates is under /site/template. Because the template should only be available in my module, I want my template file to be in /site/modules/mymodule/view/mytemplate.php When I place my file in the usual template location, it works fine. But when I place the file in my module folder, it doesn't work. When I var_dump the $page->template->filename variable, the location of the template file is correct and maps to my module folder. So everything seems to be correct, but somehow it's not working but I can't figure out the problem. Does anyone know how to solve this?
  25. hello, I want to build a custom validator on my multilang site. I added following hook, but I get only the default language value. How can I access the values of the other languages? public function init() { $this->addHookAfter("InputfieldTextarea::processInput", $this, "validateShortlinks"); } public function validateShortlinks($event) { $field = $event->object; $text = $field->value; // only the default language, how can I get the other languages? }
