helpers

问题 Does anyone know why I get undefined method `my_method' for #<MyController:0x1043a7410> when I call my_method("string") from within my ApplicationController subclass? My controller looks like class MyController < ApplicationController def show @value = my_method(params[:string]) end end and my helper module ApplicationHelper def my_method(string) return string end end and finally, ApplicationController class ApplicationController < ActionController::Base after_filter :set_content_type helper

问题 I try to follow this tutorial, but I can't get it to work: http://weierophinney.net/matthew/archives/246-Using-Action-Helpers-To-Implement-Re-Usable-Widgets.html I did everything as described, but I don't know how to make it available in my controllers.

问题 I can't figure out why the checkbox values are not saved in the database using helpers.

问题 I'm trying to search for a single filename in a bunch of directories and returning its path. I thought FileHelper::findFiles() would be a helping hand but it seems it doesn't accept a filename to search for but just a particular root directory and then it returns an array of found filenames. Anyone who knows another Yii2 helper to accomplish this? 回答1: You should simply try: $files = yii\helpers\FileHelper::findFiles('/path', [ 'only' => ['filename.ext'], 'recursive' => true, ]); Read more

问题 So I'm wanting to implement the TinyMce helper. I've followed instructions from the cakephp bakery but am still getting a error. This is the helpers array in my project controller: var $helpers = array('Form', 'Time', 'Crumb', 'Text', 'Tinymce'); This is the tinymce helper I downloaded: <?php class TinyMceHelper extends AppHelper { // Take advantage of other helpers var $helpers = array('Javascript', 'Form'); // Check if the tiny_mce.js file has been added or not var $_script = false; /** *

问题 I'm trying to determine what the best standard is for using helpers in views whether is should be echo $form->input(); or echo $this->Form->input(); In the CakePHP manual ver 1.2 the Helper class is accessed by the helper object directly, whereas in the 1.3 book the helper object is accessed through the View. Does this matter? Leo 回答1: It really only matters because of the possibility of having a collision that will "wipe out" your access to the helper. Say I had a model named Form and

问题 I'm using nested attributes, but the fields aren't loaded in my view. Someone know what I missing?

问题 I'm trying to create a function that will retrieve an order by its ID. For some reason I can't get the WooCommerce global function get_order to work. I'm passing a valid order id to the function and trying to print it out to verify that it's working. The function has been placed in my functions.php file. function getWC_order_details($id){ global $woocommerce; $order = get_order( $id ); print "<pre>"; print_r($order); print "</pre>"; } I have tested echoing other data out of the function

问题 I have the following code in my index.html.erb <%= select_tag 'team_id', options_for_select(@teams.map{|team| ["#{team.name} # {team.nick}", team.id] }) %> Where would I add a link_to helper within that block? Can I even add a link_to for select_tag? The desired link_to would go to '/Teamleader/ID_OF_OPTION_PICKED' UPDATE: To be more clear; when a user selects an option from the select tag, I want to redirect the page to the desired link (from link_to). 回答1: <%= select_tag 'team_id', options
