I've been having a bit of a struggle converting a page reference field from Select to Autocomplete, as with Select, it's possible to hook getSelectablePages, and the actual page the inputfield is on is available to the hook, but with autocomplete, you have to hook findReady, and the page the field is on is not passed to the hook, only the name of the field, which then looks up the selector string from the field definition. None of the hook arguments include the calling page, however $event->argument(0) gives the selector string, and in the field definition it is possible to include some page fields in the selector string in the field definition. eg: The problem is, typically these will affect the pages returned, but I realised that if I added at the START of the selector string in the field definition id!=page.id that will have no influence on the pages returned, as I'm not likely to want a circular reference with a page referring to itself in a page reference field, but this will provide the actual calling page id that requested the page autocomplete. Since the selector string is just a comma delimited list, it's easy enough to convert this to an array, and if I have id!=page.id as the FIRST selector parameter it's easy to get it like so: $selector = $event->arguments(0); $selectors = explode(',', $selector); $pageSelector = explode('=', $selectors[0]); $page = wire('pages')->get($pageSelector[1]); Now that I have the actual page that the autocomplete is on, I can do things beyond what is possible with the selector string in the field definition. In my case I wanted to do this: $owner = $page->parent('template=client'); //Get ancestor page with given template and retrieve a field value from it to use in selector I can then rewrite the selector string as desired. I suppose in theory it would be possible to not use the selector string in the field definition as a selector string at all, but rather as a way of passing parameters to the hook, and then just build your own selector string in the hook. I hope this helps others who've struggled with figuring out where ProcessPageSearch::findReady is being called from. It won't necessarily work for all situations but should work when called from page autocomplete. Edit: I discovered that ProcessWire adds other selectors after the last selector in the selector string in the field definition, so it's really important that id!=page.id is the FIRST parameter in the selector string in the field defintion, unless you like searching arrays. If you make it first, you just need to explode the search string, get the first array element, explode that again, and you've got the page id.

I'm trying to get a page reference field inside a repeater working with autocomplete with dependencies on other repeater fields. I'm using the Selector String option to configure page autocomplete. Currently I have: template=moveStockItem, productVintage=page.vintage.title, sort=page.vintage.title, clientCode%=page.createdUser.clientCode page.vintage.title returns nothing, as it's a field on the repeater, not a field on the page the repeater is in.

Find Merge Adds a Pages::findMerge() method that allows multiple PageFinder selectors to be merged into an efficient paginated set of results. This can be useful when you need more sophisticated sorting of results than what would be possible using only the sort value in a single $pages->find(). Details $results = $pages->findMerge($selectors, $options); $selectors is required and must be an array of selectors. Each selector can be in string format or array format. The findMerge() method will loop over the selectors in the order supplied, adding matching pages to the final results. $options is an optional associative array of options. limit (int) Limit for pagination. start (int) Manually override the start value rather than have it be automatically calculated from the current page number. excludeExisting (bool) Whether or not to exclude pages in each selector that have already been matched by a previous selector. Default is true. keepFirst (bool) When excludeExisting is false then a page might match more than one selector in the supplied array. But each page can only appear once in the results and if keepFirst is true then the page will appear in its earliest position in the results, whereas if keepFirst is false it will appear in its latest position in the results. Default is true. As a shortcut you can supply an integer as the second argument and it will be treated as the limit for pagination. Basic usage For most use cases only a limit will be needed for the $options argument. $selectors = [ 'title%=yellow', // title contains "yellow" 'title^=z', // title starts with "z" 'title=elephant', // title equals "elephant" 'template=colour, sort=-title, limit=3', // 3 colours in reverse alphabetical order 'template=country, sort=title, limit=40', // 40 countries in alphabetical order ]; $results = $pages->findMerge($selectors, 10); if($results->count) { echo "<p>Showing results {$results->getPaginationString()}</p>"; echo "<ul>"; foreach($results as $result) { echo "<li><a href='$result->url'>$result->title</a></li>"; } echo "</ul>"; echo $results->renderPager(); } Advanced usage The following notes are only relevant to rare cases and most users can safely skip this section. In the demo example the colour page Yellow will potentially match both the 1st selector and the 4th selector. Because of this the excludeExisting and keepFirst options will have an effect on the results. excludeExisting option false Note that the 4th selector asks for 3 colour pages (limit=3). By default excludeExisting is true, which means that when the 4th selector is processed it is interpreted as saying "find 3 colour pages in reverse alphabetical order that have not already been matched in an earlier selector". We can see that there are 3 pages in the results from that selector: Violet, Red, Orange. But if excludeExisting is set to false then the results are different. The matches of the 1st selector (Yellow, Yellow Warbler) are not excluded from consideration by the 4th selector (the 4th selector matches will be Yellow, Violet, Red), and because each page can only appear once in the results this means that the 4th selector ends up only adding 2 more pages to the results. $selectors = [ 'title%=yellow', // title contains "yellow" 'title^=z', // title starts with "z" 'title=elephant', // title equals "elephant" 'template=colour, sort=-title, limit=3', // 3 colours in reverse alphabetical order 'template=country, sort=title, limit=40', // 40 countries in alphabetical order ]; $options = [ 'limit' => 10, 'excludeExisting' => false, ]; $results = $pages->findMerge($selectors, $options); keepFirst option false As described above, the Yellow page potentially matches both the 1st and 4th selector. By default Yellow will appear in its earliest position within the results, i.e. the position resulting from it being matched by the 1st selector. But if keepFirst is set to false (and excludeExisting is false) then it will appear in its latest position within the results, i.e. the position resulting from it being matched by the 4th selector. $selectors = [ 'title%=yellow', // title contains "yellow" 'title^=z', // title starts with "z" 'title=elephant', // title equals "elephant" 'template=colour, sort=-title, limit=3', // 3 colours in reverse alphabetical order 'template=country, sort=title, limit=40', // 40 countries in alphabetical order ]; $options = [ 'limit' => 10, 'excludeExisting' => false, 'keepFirst' => false, ]; $results = $pages->findMerge($selectors, $options); keepFirst has no effect when excludeExisting is true. https://github.com/Toutouwai/FindMerge https://processwire.com/modules/find-merge/

Hello, I'm getting stuck trying to build a filter between subcategories and some items. For the final Item itself, I setup a reference field and wrote following selector: If there are more entries, filtering by manufacturer (which is part of the item) would be very helpful. The problem I'm stuck: How I can get and select an existing manufacturer field, which exist here: fieldset_device.manufactor I tried a hook, just not happy with the result, I despair on: $wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) { $page = $event->arguments('page'); if($event->object->hasField == 'hardware_manfilter') { $subcat = $page->hardware_subcategory; $items = $event->pages->find("parent=$subcat"); $event->return = $items->each('fieldset_device.manufactor'); } });I I appreciate any help.

Hello, can I use the selector to extract only pages with page titles longer than 10 characters? I'm looking for a way to search directly without using the php foreach statement, as shown below. $result = $this->pages->find("template!=admin, has_parent!=2, include=all"); foreach ($result as $page) { if (strlen($page->title) > 10) { $this->table[] = $page; } }

I'm trying to build a search selector that includes a checkbox multiple option field (clinicdetails_specialisms). The whole selector works fine if I don't include the checkbox field. With it included I get errors like "Error: Exception: SQLSTATE[HY093]: Invalid parameter number: mixed named and positional parameters (in wire/core/PageFinder.php line 627)". This is the selector as it currently stands. subscription_status=active,(template=user,clinicdetails_description|clinicdetails_short_description|clinicdetails_clinic_name|clinicdetails_first_name|clinicdetails_last_name*=$query),(clinicdetails_specialisms.title=$query) I've also tried setting the specialisms field in one string rather than groups and have also tried with/without the '.title' property. Oddly the selector works if specialisms is the only field being searched. It seems to fail when mixed with other selectors. Can anyone advise what stupid mistake I'm making!

Hello! I have a weird situation going on with my selector field, which I can't really get. I create an array of titles as filter using this logic: firstname=Mike|Steve id=123|124|125 title*=Red|Blue|Green This is the field I am logging: It goes in a for loop till it looks like what you see on the screen. So, my code regarding the selector string looks like this: $output = ""; foreach ($allorganisations as $item){ $output .= "$item | "; echo "<div style='color:red;'>//output String://</div>"; echo $output; } $selector_org .= ", title=$output"; I also log the output just after the matched pages are selected to be sure: $matches = $pages->find($selector_org); echo $output; foreach ($matches as $match) { echo " <li><a href='$match->url'>$match->title</a></li>"; } But you can see that it doesn't select all four needed pages, only selects one of them. Yet when I copy this exact selector text and manually put it in my selector, it works great... I even copy extra space and "|" and all that, it is supposed to be identical. I am very confused, what is the difference between the code? foreach ($allorganisations as $item){ $output .= "Institute for Scientific Research in Cosmic Anthropoecology | Institute for Scientific Research in Cosmic Anthropoecology | Stanford Research Institute | Institute for Scientific Research in Cosmic Anthropoecology | Stanford Research Institute | Institute of Clinical and Experimental Medicine | Institute for Scientific Research in Cosmic Anthropoecology | Stanford Research Institute | Institute of Clinical and Experimental Medicine | Cosmists | "; echo "<div style='color:red;'>//output String://</div>"; echo $output; } $selector_org .= ", title=$output"; } ------> If you see where I'm going wrong, please enlighten me. I am very puzzled with this behaviour . :--) Best, Ksenia

I'm having and always have a hard time building PaginatedArrays, I never know where to put the "limit=24" selector so please enlighten me. Here's what I'm doing… $categories = $page->protable('start=0, limit=999999'); // this I need in order to retrieve the pages's "categories" and I don't know how to make use of $rows instead for that purpose because of this confusing limit-API $rows = $page->protable; // put ("limit=20") here? $custom = buildSelector($input, $rows); // this function returns an array of selectors depending on the user input $items = new PaginatedArray; // or here? // or here? $items->find("limit=20") // or like this? $items("limit=20") // or like this? $items = $items("limit=20") // or like this? $items = $items->find("limit=20") foreach ($rows as $r) : if ($custom->get('selector')->matches($r)) : $items->add($r); endif; endforeach; // or at this point? and then if ($items) { // or maybe somewhere here? echo '<span class="grey">'.$items->getPaginationString(array( 'label' => 'entries', 'zeroLabel' => '0 entries', // 3.0.127+ only 'usePageNum' => false, 'count' => count($items), 'start' => $items->getStart(), 'limit' => count($items), 'total' => $items->getTotal() )); and then of course… $pager = $modules->get("MarkupPagerNav"); echo '<div class="uk-flex uk-flex-center">'.$pager->render($items, $options).'</div>'; I'm out of ideas and confused cause it doesn't make sense to me either way. ____ The buildSelector function above returns and array… $selected = new Selectors("$letter, $searchterm, $category"); $custom = new Wirearray; $custom->set('selector', $selected); $built->set('sort', $sort); return $custom; and each of the new selectors are basically strings ("category=whatever") Also, you cannot put the "sort=title" or whatever as a selector for the Selectors function (see above). Why, I know not. I don't know if that is the proper way but selecting kind of works now as opposed to many other ways I tried. Selectors always require a lot of trial and error, it seems to have a very sensitive API, always depends on double quotes, single quotes and how you concatenate. Thanks for help!

Currently I'm facing the problem that I need to select pages by a specific relation between two field values. Is it somehow possible to do something like $result = $pages->find('template=something, field1>field2'); as it would be possible to do within an SQL query? If this isn't possible, yet, I would think about ways to implement something like this e.g. by - in case of a string value - checking if the value matches one of the matched pages' field names or - to be sure it is meant to be treated as a field name - by introducing a notation like “field1=self.field2” similar to “children.count”

I want to add a dependent SELECT field on my template page that lists pages from a parent "sub-page" in the current parent node. On /product1/page I have the field "photo" which is a SELECT field. I want the SELECT to list pages from /ROOTPARENT/photos. The idea is that I can reuse the same photo in many places - but only need to keep it update it once under /product1/photos. My page structure looks like so: /product1/page /product1/photos/photo3 (template=photos) /product2/photos/photo9 I have tried adding these Selector Strings on the Field (Setup -> Fields -> PHOTO -> Input tab -> Selectable Pages field group -> Selector String): parent=/product1/page, template=photos, sort=name WORKS (but only on children of current product). parent=page.rootParent ... parent=$page.rootParent ... parent=$page.rootParent parent=$parent ... parent=$parent1 When using a SELECT Input Field Type, the editing pages gives the fatal error "Unrecognized operator: $". parent=parent ... parent=. Returns an empty list How might I find child pages from the current "/product1/photos/ page"? Your inputs are appreciated. Thanks.

Hello, I've just upgraded to 3.0.165 (and updated my Ubuntu version as well) and on my localhost, I am facing a weird issue : all my requests having the ~= selector cause a Mysql error with this message : PDOException #HY000 SQLSTATE[HY000]: General error: 3685 Illegal argument to a regular expression. I have no idea what is going on. If I change my request from $visualizer = $pages->get("name~=visualizer"); // Triggers the error to $visualizer = $pages->get("name=visualizer"); or $visualizer = $pages->get("name~*=visualizer"); My code works fine again. Any idea ? Shall I change all my requests (but from what I understand by reading the documentation, ~= exists and fits my needs : all words in any order [though I do understand that in my example above it may be useless since I have only one word]) Thanks !

I want to allow full text search on my site. There is a very nice solution that comes right out of the box: $selector = "title|body~=$q, limit=50"; This works, but to make it even better I would want to give higher weight to pages where the search term occurs in the title, than if it just occurs in the body. After all, a page with the title "Wine from France" is probably the best match for the search "france wine". How do I accomplish this in ProcessWire? I can see three possible paths, but I am not very fond of any of them: Do a direct SQL query, circumventing the API, along these lines. But I would prefer to abstract away the database layout if at all possible. Use something like ElasticSearch, but to be honest that would be to complicated to set up and maintain in the long run. Make multiple lookups, first for matches in the title, then for matches in the body, and merge and sort in PHP. My suspicion is that this would get complicated quite quickly. For instance, how do you deal with a page that has two of the three search terms in the title and the third in the body? Is there a magic option four I should look into? Or are any of the above options better than the others? Any input is welcome!

Hi! I have two Page Reference fields: Category and Subcategory. Category is parent of Subcategory, and can have 0 to n Subcategories. Fields are selected by dropdown selection. I'm trying to achieve following logic: 1. Select Category (obviously works) 2. Change Subcategory options based on selected Category (this works) 3. Hide the Subcategory field if Category has no Subcategories (to prevent weird dropdown with nothing to select) I have tried to investigate two possible alternatives to achieve step 3: A) Make dynamic condition into Subcategory selection's "Only visible if..." field B) Make a hook that fires when Category changes, then hides Subcategory field if Category has no children So far I haven't been successful in either. Conditions I've tried always lead to hidden field, and I haven't been able to find set up a hook that fires on field change. So here's the question (finally): Is there a way to alter field visibility in API, for example in ready.php or inside a hook? In API I could loop through categories, find the ones that have children and then make a selector based on their IDs.

selectors Start operator ignored if limit is not set
schwarzdesign posted a topic in General Support
I'm working on a news feed that will show the most recent news in a full teaser grid, and all older news as a simpler archive-type list view. My selectors so far: $news_full = $page->children("template=news, limit={$page->feed_count_full}"); $news_archive = $page->children("template=news, start={$page->feed_count_full}, limit=9999"); The $page->feed_count_full field controls how many items to show in the teaser grid (I've confirmed it contains the correct value, and the $news_full selector works as intended). This works, but I don't like the limit in the second selector. Unfortunately, if I leave it out (i.e. I only specify a start, not a limit), the start is ignored and I get all news instead. Not a big problem as we will never have more than 9999 news, but it still bothers me, as semantically speaking I don't want to set a limit in this case. Is this the intended behaviour of start/limit selectors? Is there a cleaner way to specify an offset (start selector) without a limit? ProcessWire Version 3.0.123 Thanks! -
I played with the Selectors object and would like to use it for a special use case... That is a custom Selectors object with dummy data converted to an php array to see the structure (Selectors object is a WireArray with "fields" added) Array ( [0] => Array ( [0] => Array ( [field] => seg1 [value] => val1 [not] => [group] => [quote] => [forceMatch] => ) [1] => Array ( [field] => seg2 [value] => val2 [not] => [group] => [quote] => [forceMatch] => ) ) ) But instead of "seg1" the field name is "field" with value "seg1" (= my field name). So I can't search the Selectors WireArray (= custom WireArray with added Selectors objects) with PW "find('seg1=val1')", Is there a way to search with "find()" or build a simple wrapper to make the elements searchable / filterable with find()?

Hello. I'm really enjoying going into ProcessWire after using Drupal, CodeIgniter and FuelPHP for a while. Anyway my first question is with this bit of code $items = $page->siblings("template=portfolio-item, sort=random, path!={$page->path}"); As you can see, I'm trying to get siblings of the page, excluding current one. But instead it returns ONLY current page, as if there was no exclamation mark in the path selector. What's the problem here? Update: Okay, have found solution here http://processwire.com/talk/topic/1230-limit-siblings-after-removing-page/ Still curious about path selector behaviour though.

Hi there! And thanks for Processwire! It appears that i've found something interesting about PW selectors. They should only be strings! Here's an example of SQL-like syntax for selector: $my_complex_selector = " name='some name', parameter=123, other_parameter=[subparam>=subvalue] "; Trying to use this selector lead to a very buggy PW behaviour. It appears that newlines are treated in a very special manner by PW selector engine, preventing the newlined selectors from working as expected. I cannot imagine a situation when an unescaped newline could be a part of selector or selector value, so stripping newline symbols from selector could be a good idea for further PW development. And, currently, another good idea is to write complex selectors as PHP arrays: $my_complex_selector = [ "name=$name", "param1=$param1", ]; and to implode them into a single line before using find() and other functions which use selectors. Sorry if i wrote something trivial, but having this post already present at support forum could save me a couple of hours. Hope mine will save that tame for someone else ?

Apologies if this has been covered. I tried a search but didn't hit the usecase I'm after. I currently have category pages listing their children products. Someone asked me to put a product in multiple categories, so I created a Page Reference field called prod_othercategories which lets a user pick multiple product category pages. When I try to output a list of products for a category page, I came around to the following selector: $pages->find("prod_othercategories|parent=$page, template=prod_series, sort=title, prod_status_pages!=1554|1559|1560|4242"); Only the first selector item is giving me trouble, but I'm including the entire string in case something is conflicting and I'm not realizing it. The output is currently only outputting matches for "parent" and ignoring prod_othercategories. I tried listing parent first in the selector but it had no effect. Appreciate if someone could help me with this! Thanks!

I don't know if this is the right place, it's not really a tutorial, just a tip based on notes I wrote myself in a recent project to get it straight in my own head. I thought it might be useful for others in a similar situation. Scenario: Create a search function that will search for keywords "foo" and "bar" in multiple fields, but the keywords do not have to be adjacent, in order, or even all in the same field. For eample, the selector must match if "foo" is in "field_a" and "bar" is in "field_b" -- so long as both keywords are present somewhere, the page match is valid. It is possible to just split the terms and do multiple queries on each field separately and then combine the results into a single PageArray for pagination (I believe there is a module that helps with this). However, I wanted to see if it was possible to do a basic version with a single query. Not The Solution: The following selector does not work when keywords appear separately in different fields (operator '~=' - contains all the words): $selector = "title|field_a|field_b~=foo bar"; What the selector is saying: FIND BOTH "foo" AND "bar" IN title OR FIND BOTH "foo" AND "bar" IN field_a OR FIND BOTH "foo" AND "bar" IN field_b In this case, both "foo" and "bar" have to be in the same field (but not adjacent or in order) to match. The Actual Solution What we need to use is "named selectors" to let us match each individual keyword separately while still using one selector. Using the same example as before: $selector = "selector1=(title|field_a|field_b~=foo), selector2=(title|field_a|field_b~=bar)"; What the selector is saying at its most basic level: FIND BOTH selector1 AND selector2 Or, to expand on this, it is saying: (FIND "foo" IN title OR field_a OR field_b) AND (FIND "bar" IN title OR field_a OR field_b) Crucially, "foo" and "bar" do not have to be in the same field to match. Practical Method In this example code, I am actually allowing the search for phrases (using "quoted text") as well as individual terms, so a person could enter... "foo bar" baz ... and it will keep "foo bar" together aa one term and "baz" as a separate term and match them as an exact phrase. // Keywords obtained from $input->get and cleaned (multiple spaces removed)/sanitized etc. $keywords = '"foo bar" baz'; // Split into individual search terms by space (preserve spaces in quoted text) $terms = str_getcsv($keywords, " "); // array("foo bar", "baz") // Build up named selectors $ns = ""; // named selectors string $i=1; // named selector count foreach ($terms as $term) { // operator '*=' - contains the exact word or phrase $ns .= ", ns{$i}=(title|field_a|field_b*=" . trim($term) . ")"; $i++; } //$ns = ", ns1=(title|field_a|field_b*=foo bar), ns2=(title|field_a|field_b*=baz)" // Construct the whole selector (modify/add other general selectors as needed) $selector = "template=my-template, limit=20, sort=-date" . $ns; // Find pages based on selector $results = $pages->find($selector); DISCLAIMER I haven't done any tests to see if this method is more efficient than running queries on each field separately and combining the results, I just wanted to see if it was possible!

Hello girls and guys, i just saw that if I use a selector on a textarea, for example $pages->find('body%=notes') it also find that key in html classes and attributes. For example it will find <p class="text-notes">Lorem ipsum dolor sit amet cosectetur.</p> Is there a way to avoid this anche check only the texts without the html tags? Thanks!

Hi there! And thanks for Processwire! This is rather a question than a feature request, maybe there's a well known solution which i missed. So what about aggregation in selectors? Let's suppose we have a PW-powered shop where any product has a rating made by customers. Every time the user polls two data fields are updated: points and votes. The rating is calculated as this: $rating = $page->points / $page->votes; It was easy, yeah. But what about sorting products by their rating? Basically there are two ways of doing it: Creating one more field called rating and updating it after every vote. For sure it will work, but we have to create an extra data field which in fact stores data based on two another fields. Bad practice i think. Getting all products into array and applying a cutom sort function. Will work again, but this demands much more coding than using the native PW selectors. But how could it be done in the best possible way? Let's imagine this: $products = $page->children("sort=points/votes"); Or maybe this: function rating($a,$b){ return $a->points/$a->votes > $b->points/$b->votes; } $products = $page->children("sort=rating()"); Okay, let's go even deeper. Maybe we need "virtual" fields which are not stored in DB tables like other PW fields but represent the dynamically calculated values? $page->rating = function(){ return $page->points/$page->votes; } $products = $page->children("sort=rating"); Will be glad to see advice on the best practices. Thanks in advance!

Hi, I'm having problems with seatching for a value in repeater. One of pages have attached repeater called 'insight_repeater'. This repeater has h1_tag (text field) and i'm trying to search for repeater items that contains 'lor' phrase. And right now i'm trying to do simple search, looking for phrase 'lor'. I've tried many approaches, but nothins seems to work, so i want to ask what i'm doing wrong here: <?php $query = $page->get("insight_repeater")->find('h1_tag~=Lor'); ?> Thanks for help.

Hi all, I'm having an odd issue that I think is down to the selector I'm using but I can't track down the cause! I'm using front-end AJAX search form on a list of product adverts (pages) where the product is made by a certain manufacturer (vendor). The manufacturer is chosen buy the person listing the adverts from a page field list of manufacturers who's parent is id=1034. Most manufacturers are being found without an issue. The only one that's causing a problem is called 'Proj-ect" (the "-" being part of their brand name. Here's my selector code: $thisBrandProducts = $pages->find("template=advert,vendor.title~=$q,has_parent=1034,limit=20,created_users_id!=$susDealerList"); $susDealerList is a list of advertisers that are not currently live so pages should be excluded. Could the "-" in the name be the issue with those pages not being returned? If so does anyone have any ideas of how I can get around this? Thanks in advance!

Hello there! And thanks for Processwire! It may appear a noob question but what about selectors like "field1=val1||field2=val2"? I mean that the page we're looking for should have field1=val1 OR field2=val2 . There's plenty of examples for cases like "field=val1|val2" but it's another case. Practical example: frontpage uder registration. User should enter nick and email, and both of them should be unused by other registered users. It's logical to use something like $userTest = $users->get("nick={$input->post->nick}|email={$input->post->email}"); But this doesn't work. That's the best practice in this case? Thanks in advance!
