API Cheat Sheet

Here are all the functions you will be using inside your EntityCrudController's setup() method, grouped by the operation you will most likely use them for.




// Manipulate what columns are shown in the table view.
$this->crud->addColumn($column_definition_array); // add a column, at the end of the stack
$this->crud->addColumns([$column_definition_array, $another_column_definition_array]); // add multiple columns, at the end of the stack
$this->crud->modifyColumn($name, $modifs_array);
$this->crud->removeColumn('column_name'); // remove a column from the stack
$this->crud->removeColumns(['column_name_1', 'column_name_2']); // remove an array of columns from the stack
$this->crud->setColumnDetails('column_name', ['attribute' => 'value']);
$this->crud->setColumnsDetails(['column_1', 'column_2'], ['attribute' => 'value']);

$this->crud->setColumns(); // set the columns you want in the table view, either as array of column names, or multidimensional array with all columns detailed with their types

$this->crud->addColumn()->beforeColumn('name'); // will show this before the given column
$this->crud->addColumn()->afterColumn('name'); // will show this after the given column

  // will make this column the first one in the list
  // you need to also specify priority 1 in your addColumn statement for details_row or responsive expand buttons to show


// possible positions: 'beginning' and 'end'; defaults to 'beginning' for the 'line' stack, 'end' for the others;
$this->crud->addButton($stack, $name, $type, $content, $position); // add a button; possible types are: view, model_function
$this->crud->addButtonFromModelFunction($stack, $name, $model_function_name, $position); // add a button whose HTML is returned by a method in the CRUD model
$this->crud->addButtonFromView($stack, $name, $view, $position); // add a button whose HTML is in a view placed at resources\views\vendor\backpack\crud\buttons
$this->crud->removeButtonFromStack($name, $stack);


// Manipulate what filters are shown in the table view.
// Note: check out CRUD > Features > Filters in the docs to see examples of $filter_definition_array
$this->crud->addFilter($filter_definition_array, $values, $filter_logic);
$this->crud->modifyFilter($name, $modifs_array);
$this->crud->filters(); // gets all the filters

Details Row

// Shows a + sign next to each table row, so that the user can expand that row and reveal details. You are responsible for creating the view with those details.
// NOTE: you also need to do allow access to the right users: $this->crud->allowAccess('details_row');
// NOTE: you also need to do overwrite the showDetailsRow($id) method in your EntityCrudController to show whatever you'd like in the details row OR overwrite the views/backpack/crud/details_row.blade.php


Export Buttons

// Show export to PDF, CSV, XLS and Print buttons on the table view. Please note it will only export the current _page_ of results. So in order to export all entries the user needs to make the current page show "All" entries from the top-left picker.

Responsive Table


Page Length

$this->crud->setDefaultPageLength(10); // number of rows shown in list view
$this->crud->setPageLengthMenu([100, 200, 300]); // page length menu to show in the list view

Actions Column

// make the actions column (in the table view) hide when not enough space is available, by giving it an unreasonable priority

Custom / Advanced Queries

// Change what entries are shown in the table view.
// This changes all queries on the table view,
// as opposed to filters, who only change it when that filter is applied. 
$this->crud->addClause('active'); // apply local scope
$this->crud->addClause('type', 'car'); // apply local dynamic scope
$this->crud->addClause('where', 'name', '=', 'car');
$this->crud->addClause('whereName', 'car');
$this->crud->addClause('whereHas', 'posts', function($query) {

// please note it's generally a good idea to use crud->orderBy() inside "if (!$this->request->has('order')) {}"; that way, your custom order is applied ONLY IF the user hasn't forced another order (by clicking a column heading)


Use the same Columns API as for the ListEntries operation, but inside your show() method.

Create & Update Operations

// ------
// ------
// Manipulate what fields are shown in the create / update forms.
// Note: check out CRUD > Features > Field Types in the docs to see examples of $field_definition_array

$this->crud->addField($field_definition_array, 'update/create/both');
$this->crud->addField('db_column_name', 'update/create/both'); // a lazy way to add fields: let the CRUD decide what field type it is and set it automatically, along with the field label
$this->crud->addFields($array_of_fields_definition_arrays, 'update/create/both');
$this->crud->modifyField($name, $modifs_array, 'update/create/both');
$this->crud->removeField('name', 'update/create/both');
$this->crud->removeFields($array_of_names, 'update/create/both');

// Note: the last parameter is always the form - create or update; if missing, it's assumed 'both';

$this->crud->addField()->beforeField('name'); // will show this before the given field
$this->crud->addField()->afterField('name'); // will show this after the given field


// Show a reorder button in the table view, next to Add
// Provide an interface to reorder & nest elements, provided the parent_id, lft, rgt, depth columns are in the database, and fillable on the model.
$this->crud->enableReorder('label_name', 3);
// NOTE: the second parameter is the maximum nesting depth; this example will prevent the user from creating trees deeper than 3 levels;
// NOTE: you also need to do allow access to the right users: $this->crud->allowAccess('reorder');

$this->crud->isReorderEnabled(); // return true/false


// -------------------------
// REVISIONS aka Audit Trail
// -------------------------
// Tracks all changes to an entry and provides an interface to revert to a previous state.
// IMPORTANT: You also need to use \Venturecraft\Revisionable\RevisionableTrait;
// Please check out: https://backpackforlaravel.com/docs/crud-operation-revisions

All Operations

// ------ 
// ------
// Prevent or allow users from accessing different CRUD operations.

$this->crud->allowAccess(['list', 'create', 'delete']);
$this->crud->denyAccess(['list', 'create', 'delete']);

$this->crud->hasAccess('add'); // returns true/false
$this->crud->hasAccessOrFail('add'); // throws 403 error
$this->crud->hasAccessToAll(['create', 'update']); // returns true/false
$this->crud->hasAccessToAny(['create', 'update']); // returns true/false

// -------------
// -------------

// eager load a relationship

// ------------
// ------------

// use a custom view for a CRUD operation

// -------
// -------



// in your update() method, after calling parent::updateCrud()

// -------
// -------

$this->crud->getActionMethod(); // returns the method on the controller that was called by the route; ex: create(), update(), edit() etc;
$this->crud->actionIs('create'); // checks if the controller method given is the one called by the route

// ---------------------------
// CrudPanel Basic Information
// ---------------------------
// OR $this->crud->setRouteName("admin.example");
$this->crud->setEntityNameStrings("example", "examples");

// check the FormRequests used in that EntityCrudController for required fields, and add an asterisk to them in the create/edit form
$this->crud->setRequiredFields(StoreRequest::class, 'create');
$this->crud->setRequiredFields(UpdateRequest::class, 'edit');
