Thanks to the great Pro module "RepeaterMatrix" I have the possibility to create complex repeater items. With it I have created a quite powerful page builder. Many different content modules, with many more possible design options. The RepeaterMatrix module supports the cloning of items, but only within the same page. Now I often have the case that very design-intensive pages and items are created. If you want to use this module on a different page (e.g. in the same design), you have to rebuild each item manually every time.
With this proof of concept I have created a module which adds the feature to copy a repeater item to the clipboard so that you can paste this item to another page with the same repeater field. The module has been developed very rudimentarily so far. It is currently not possible to copy nested items. There is also no check of Min/Max. You can also only copy items that have the same field on different pages. And surely you can solve all this more elegantly with AJAX. But personally I lack the deeper understanding of the repeaters. Also missing on the Javascript side are event triggers for the repeaters, which would make it easier. Like e.g. RepeaterItemInitReady or similar.
it would be great if @ryan would implement this functionality in the core of RepeaterMatrix. I think he has better ways to implement this. Or what do you think, Ryan?
Everybody is welcome to work on this module and improve it, if it should not be integrated into the matrix core. Therefore I put it for testing and as download on GitHub: https://github.com/FlipZoomMedia/InputfieldRepeaterMatrixDublicate

Hi,
For the purpose of learning, as shown in this photo, I created a repeater field "we", then a template, then a page.
But in /templates/testrepeater.php, I has some problem, the "foreach" part does not work as expected.
<html> <body> <?php echo "<h1>$page->title</h1><br>"; ?> <? foreach($page->we as $member); ?> <img src="<?php echo $member->images->url; ?>" alt=""> <?php echo $member->wemember; ?><br> <? endforeach;?> </body> </html> Could anybody please help point out my error?
Thanks in advance.

Hi All,
I've made a previous regarding an issue which I solved but I stumbled across a new issue :). Below again the explanation needed.
You need a short introduction for this. The company I am working for has approx. 80 products on their website and they all have their own features. The features are imported from an older system which isn't used anymore. Back then, when they changed from the old system to PW, we imported the features into the product pages as a JSON-array so the pages could load a bit faster as exploding a JSON array is a bit faster than loading in a lot of items from a table or a repeater field.
How the JSON array looks like:
{ "2": { // The ID of the group that contains the actual features "name": "Model and function", // The name of the group "features": { "43": { // Attribute ID "name": "Resolution (DPI)", // Attribute name "values": { "896": "500-1500-2000-3500" // Value ID and value name } } } } } Now we are adding a few more products to the catalog with new features and some that are already in use by other products but I am really struggling to assign the right ID's with the correct values in 7 different languages without messing up filters etc. So I decided to develop a module that lets you easily add feature groups, attributes and values as pages and connect these to the product using a repeater. This started by exporting all the current groups, attributes and values and import them as pages in the following structure:
- Features - Feature Groups - Group 1 - Group 2 - ... - Feature Attributes - Attribute 1 - Attribute 2 - ... - Feature Values - Value 1 - Value 2 - ... Secondly, I created a repeater field that I assigned to the 'Features'-page that can handle the JSON structure explained above by seeing each item of the repeater field as a group. Inside each item you can select the group page and you will find another repeater which contains 2 page selectors to select an attribute and a value. A single repeater field looks like this:
Next step was to create a module that gets this field as an Inputfield from the Features page. Once the user has finished adding groups, attributes and values he can click on save and I export all the values in the same JSON array structure as earlier but now the ID's of the groups, attributes and values are just the page ID's. This works great to add new features to new products.
BUT, sometimes the features of a product change or need to be changed and you don't want to change the JSON array manually.
So my idea was to do the same thing as adding the features, but now you grab the values from the product first and populate the items of the repeater field.
$featuresPage = wire("pages")->get("template=features"); $featureGroups = json_decode($product->features, true); foreach ($featureGroups as $featureGroupID => $featureGroup){ $row = $featuresPage->features_repeater->getNewItem(); $groupPage = wire("pages")->get($featureGroupID); $row->feature_group_selector = $groupPage; $row->save(); foreach ($featureGroup["features"] as $featureID => $feature){ $featuresRow = $row->feature_repeater->getNewItem(); $attributePage = wire("pages")->get($featureID); $valuePage = wire("pages")->get(key($feature['values'])); $featuresRow->feature_attribute_selector = $attributePage; $featuresRow->feature_value_selector = $valuePage; $featuresRow->save(); } $row->save(); } $featuresPage->save(); $f = wire('fields')->get('features_repeater'); $inputfield = $f->getInputfield($featuresPage); $form->add($inputfield); $f = $this->modules->get("InputfieldSubmit"); $f->name = 'updateFeatures'; $f->label = 'Update Features'; $f->icon = 'plus'; $f->value = 'Update Features'; $form->add($f); Then the user can change / add features, click save and done!
It is possible to update the feature attributes and values, but when I change the feature group value, it seems like PW creates a new field behind the scenes and keeps the old value as well. So let's say I have the following feature structure:
- Feature Group 1 - Feature attribute 1 - Feature value 1 Now I want to update Feature Group 1 to Feature Group 2, below is the desired result and the actual result:
// === Desired result - Feature Group 2 - Feature attribute 1 - Feature value 1 // === Actual result - Feature Group 2 - Feature attribute 1 - Feature value 1 - Feature Group 1 - Feature attribute 1 - Feature value 1
I am using the following function to update the features:
private function processForm5_UpdateFeatures(InputfieldForm $form){ $form->processInput($this->input->post); if (count($form->getErrors())) return false; $pageID = $this->session->selectedProduct; $product = wire('pages')->get($pageID); $product->of(false); $repeater = $form->get("features_repeater")->value; $languages = wire("languages"); foreach ($languages as $language) { $return_array = []; $i = 0; foreach ($repeater as $repeaterItem) { //$this->message($repeaterItem); $group = $repeaterItem->feature_group_selector; if ($group["id"] == 0) { continue; } else { $group = wire("pages")->get($group["id"]); $feature_group_name = &$return_array[$group->id]['name']; if (!isset($feature_group_name)) $feature_group_name = $group->title->getLanguageValue($language); $features = $repeaterItem->feature_repeater; foreach ($features as $feature) { $this->message($feature); $attribute = $feature->feature_attribute_selector; $value = $feature->feature_value_selector; if ($attribute["id"] == 0 || $value["id"] == 0) { continue; } else { $attribute = wire("pages")->get($attribute["id"]); $value = wire("pages")->get($value["id"]); $return_array[$group->id]['features'][$attribute->id]['name'] = $attribute->title->getLanguageValue($language); $return_array[$group->id]['features'][$attribute->id]['values'][$value->id] = $value->title->getLanguageValue($language); } } } } $product->features->setLanguageValue($language->name, json_encode($return_array, JSON_UNESCAPED_UNICODE)); } $product->save(); $featuresPage = wire("pages")->get("template=features"); $featuresPage->features_repeater->removeAll(); $featuresPage->save(); /* $this->messages("clear all"); $this->errors("clear all");*/ $this->message("Updated all features for {$product->title}"); $this->session->redirect("../"); } Is there a way to avoid the current result and get the desired result? Why is there even a new repeater page created for the new value? Anything that can help me is greatly appreciated!

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 } } });

Hi
My first use of repeaters. They seem very useful, but I'm having a strange problem with the descriptions of the images field. I can't change them after deploying from my local dev server to the live server. I have defined a repeater with one images field and one textarea (multi language) field. This works as expected when added to a template and on the page I add an image and text in 3 languages. I usually populate the image description fields with a caption text in 3 languages so that I can output a caption if required under the image. Now this all works a treat on my test localhost server, but when deployed to the live site the captions cannot be changed on these repeater image fields. If I login to the live site and change the image text in there - as soon as I hit save the text goes back to what it was before! I am logged in as superuser so can't work out what the problem is.
I had a search through the forums but couldn't find a similar problem. Any ideas where to look for some clues to what the problem may be?
I'm using ProcessWire 3.0.96
Many thanks - Paul
