Lock repeater item for editing

Recommended Posts


I would like to prevent future editing of a repeater item once a checkbox in the repeater item has been checked. Either the form inputs of the repeater item should be read only or only the field values should be rendered.

Looking at the module code I can't seem to figure out where to hook for that functionality.

Any ideas would be much appreciated.

A quick&dirty piece for site/ready.php. The collapsed status still needs some working on, but it appears to also be working in ajax mode:

wire()->addHookAfter("Field::getInputfield", null, "hookGetInputfield_lockCheckedRepeaters");

function hookGetInputfield_lockCheckedRepeaters(HookEvent $event) {
	$thisPage = wire('page');
	// Only run our locking logic if we are editing the page in the backend
	if($thisPage->process != "ProcessPageEdit") return;
	// We don't want to lock the repeater itself (or do we?)
	if($event->object->type instanceOf FieldtypeRepeater) return;
	$repPage = $event->arguments(0);
	$context = $event->arguments(1);
	// The backend retrieves the field within the repeater context, otherwise something else
	// is happening we do not want any part of ;-)
	if($context != "_repeater" . $repPage->id) return;
	// Set collapsed status in the input field (the event's return), could be made a little
	// more elaborate
	$event->return->collapsed = ($event->return->collapsed === Inputfield::collapsedNo || $event->return->collapsed === Inputfield::collapsedNoLocked) ?
								Inputfield::collapsedNoLocked :

Probably obvious, but if you want to lock only repeater items that have the checkbox checked then you would add a conditional for that in the hook that BitPoet suggested.

if($repPage->your_checkbox) {
    $event->return->collapsed = ($event->return->collapsed === Inputfield::collapsedNo || $event->return->collapsed === Inputfield::collapsedNoLocked) ?
        Inputfield::collapsedNoLocked :

@BitPoet Thank you very much for the heads-up. Also to @Robin S.

I finally ended up with this hook function in a module context which does exactly what I need, also in ajax mode:

    $this->addHookAfter('Field::getInputfield', $this, "lockConfirmedItems");
    public function lockConfirmedItems(HookEvent $event) {

		if($this->user->isSuperuser() || $this->user->hasRole('certificationadmin')) return;
		$thisPage = wire('page');
		// // Only run our locking logic if we are editing a user in the backend
		if($thisPage->process != "ProcessUser") return;
		$repeaterPage = $event->arguments(0);
		$context = $event->arguments(1);
		if($context != "_repeater" . $repeaterPage->id) return;
		if(!$repeaterPage->confirmed) return;
		$event->return->collapsed = 7;


Setting collapsed with the Inputfield constants like in BitPoet's code didn't work for me.

I would like to lock a specific repeater item with the id 1553 to prevent editing from non-superusers but none of the above work. Can you please help?

	$inputfield = $event->return;
	// Only for non-superusers
	if($event->wire('user')->isSuperuser()) return;
	// Only for a particular Repeater page ID
	if($page->id !== 1553) return;
	// Set collapsed to Inputfield::collapsedNoLocked or Inputfield::collapsedHidden as suits
	$inputfield->collapsed = Inputfield::collapsedNoLocked;

      Hi 👋
      Anyone else having this problem?
      - Repeater (matrix & normal) with mutlilanguage fields (text, textarea…) 
      - Backend language set to something other than default (ie. German) 
      - Add a new repeater Item (ajax, I found no way to possible to disable it with matrix)

      (Notice how the default language tab is active instead of the backend language…)
      - Write something into the (default language) field
      - Try to save, if field is required, this will not work. If not required, then when reloading, the content will be inside the backend language field, instead of the default language field who was (presumably) active
      When  loading  a new repeater element with ajax, the default langue tab is active, but the backend language inputfield is visible (with no visual indication). When writing into the field, it will populate the backend language. When manually clicking on the default language tab (which is already active), the field will switch to the actual default language field (which is [now] empty) (that can now be populated…)
      Also Notice, the labels of the elements to be added are in default language as well instead of the translated label (images instead of Bilder)…
      ProcessWire 3.0.148, Profields 0.0.5…
      Is it my system configuration, or does anyone else have the same issue? This is a screen recording of the problem:

      ProcessWire InputfieldRepeaterMatrixDuplicate
      Thanks to the great ProModule "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 a content module on a different page (e.g. in the same design), you have to rebuild each item manually every time.
      This module extends the commercial ProModule "RepeaterMatrix" by the function to duplicate repeater items from one page to another page. The condition is that the target field is the same matrix field from which the item is duplicated. This module is currently understood as proof of concept. There are a few limitations that need to be considered. The intention of the module is that this functionality is integrated into the core of RepeaterMatrix and does not require an extra module.
      Check out the screencast
      What the module can do
      Duplicate a repeater item from one page to another No matter how complex the item is Full support for file and image fields Multilingual support Support of Min and Max settings Live synchronization of clipboard between multiple browser tabs. Copy an item and simply switch the browser tab to the target page and you will immediately see the past button Support of multiple RepeaterMatrix fields on one page Configurable which roles and fields are excluded Duplicated items are automatically pasted to the end of the target field and set to hidden status so that changes are not directly published Automatic clipboard update when other items are picked Automatically removes old clipboard data if it is not pasted within 6 hours Delete clipboard itself by clicking the selected item again Benefit: unbelievably fast workflow and content replication What the module can't do
      Before an item can be duplicated in its current version, the source page must be saved. This means that if you make changes to an item and copy this, the old saved state will be duplicated Dynamic loading is currently not possible. Means no AJAX. When pasting, the target page is saved completely No support for nested repeater items. Currently only first level items can be duplicated. Means a repeater field in a repeater field cannot be duplicated. Workaround: simply duplicate the parent item Dynamic reloading and adding of repeater items cannot be registered. Several interfaces and events from the core are missing. The initialization occurs only once after the page load event Changelog
      Bug fix: Various bug fixes and improvements in live synchronization Bug fix: Items are no longer inserted when the normal save button is clicked. Only when the past button is explicitly clicked Feature: Support of multiple repeater fields in one page Feature: Support of repeater Min/Max settings Feature: Configurable roles and fields Enhancement: Improved clipboard management Enhancement: Documentation improvement Enhancement: Corrected few typos #1 1.0.3
      Feature: Live synchronization Enhancement: Load the module only in the backend Enhancement: Documentation improvement 1.0.2
      Bug fix: Various bug fixes and improvements in JS functions Enhancement: Documentation improvement Enhancement: Corrected few typos 1.0.1

      Wouldn’t it be cool to have whole repeater items (or even repeater matrix items) language-specific. Some of my clients do have pages that are 90% identical in German and English, but there are some sections that should not appear in one or another language. I attached a concept screenshot.
      Would something like this be possible with some simple backend hooks and "hidden checkbox fields"? Or is it way more complicated?

      I've ran into an issue with adding a repeater field to a template.
      The page editor in the backend shows the fields and the data attached to the fields, including the repeater.
      However, when viewing the template in the front-end, there is no sign of a repeater field in the data set.
      ["data"]=> array(3) { ["name1189"]=> string(11) "partenaires" ["status1189"]=> string(1) "1" ["title"]=> string(8) "Partners" } } Do u have any idea what could be causing this issue?
      I've tried recreating the field and there is no caching active, but still can't get the repeater in the data set.

      Repeater Images
      Adds options to modify Repeater fields to make them convenient for "page-per-image" usage. Using a page-per-image approach allows for additional fields to be associated with each image, to record things such as photographer, date, license, links, etc.
      When Repeater Images is enabled for a Repeater field the module changes the appearance of the Repeater inputfield to be similar (but not identical) to an Images field. The collapsed view shows a thumbnail for each Repeater item, and items can be expanded for field editing.

      Install the Repeater Images module.
      Create an image field to use in the Repeater field. Recommended settings for the image field are "Maximum files allowed" set to 1 and "Formatted value" set to "Single item (null if empty)". Create a Repeater field. Add the image field to the Repeater. If you want additional fields in the Repeater create and add these also. Repeater Images configuration
      Tick the "Activate Repeater Images for this Repeater field" checkbox. In the "Image field within Repeater" dropdown select the single image field. You must save the Repeater field settings to see any newly added Image fields in the dropdown. Adjust the image thumbnail height if you want (unlike the core Images field there is no slider to change thumbnail height within Page Edit). Note: the depth option for Repeater fields is not compatible with the Repeater Images module.
      Image uploads feature
      There is a checkbox to activate image uploads. This feature allows users to quickly and easily add images to the Repeater Images field by uploading them to an adjacent "upload" field.
      To use this feature you must add the image field selected in the Repeater Images config to the template of the page containing the Repeater Images field - immediately above or below the Repeater Images field would be a good position.
      It's recommended to set the label for this field in template context to "Upload images" or similar, and set the visibility of the field to "Closed" so that it takes up less room when it's not being used. Note that when you drag images to a closed Images field it will automatically open. You don't need to worry about the "Maximum files allowed" setting because the Repeater Images module overrides this for the upload field.
      New Repeater items will be created from the images uploaded to the upload field when the page is saved. The user can add descriptions and tags to the images while they are still in the upload field and these will be retained in the Repeater items. Images are automatically deleted from the upload field when the page is saved.
      The "Use accordion mode?" option in the Repeater field settings is useful for keeping the inputfield compact, with only one image item open for editing at a time. The "Repeater item labels" setting determines what is shown in the thumbnail overlay on hover. Example for an image field named "image": {image.basename} ({image.width}x{image.height})
