在HABTM复选框旁边显示图像

本文介绍了在HABTM复选框旁边显示图像的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 甘蔗有人请给我一个想法！ 我从一个与另一个具有HABTM关系关联的表相关的表中生成多个复选框。 我想生成带有图像以及标签中文本的多个复选框。 我的两个表是项目和items_characteristics。因此，一个项目具有HasAndBelongToMany特性，而一个项目具有特性HasAndBelongToMany Items。 echo $ this-> Form-> input（'Item.ItemCharacteristic'，array（'label '=> false，'type'=>'select'，'multiple'=>'checkbox'，'options'=> $ itemCharacteristics，'selected'=> $ this-> HTML-> value（'ItemCharacteristic.ItemCharacteristic'）））; 此代码可正确生成复选框列表，并且可以正常运行：这就是我有： 这是我想拥有的： 任何人都不知道如何我可以实现吗？解决方案我假设在您的控制器中您执行了以下操作： $ this-> request-> data = $ this-> Item-> find（'first'，...）; ，以便 $ data 包含有关 编辑：我还假设 Item habtm ItemCharacteristic 然后在您看来 $ checked_characteristics = Hash :: extract（$ this-> data，'ItemCharacteristic。{n} .id'）; foreach（$ itemCharacteristics as $ id => $ itemCharacteristic） { $ checked = in_array（$ id，$ checked_characteristics）; $ img = $ this-> HTML-> image（’cake.icon.png’）; //将要显示的图标的名称 //放在此处 //根据特征 //您正在显示 echo $ this-> Form- > input（'ItemCharacteristic.ItemCharacteristic。'， array（'between'=> $ img，'label'=> $ itemCharacteristic，'value'=> $ id，'type'=>'checkbox'，'checked'=> $ checked ））; } 编辑：从您的评论中我了解到 $ itemCharacteristics 来自 find（'list'）语句。 将其更改为 find（'all'，array（'recursive'=> -1））; 现在您的代码变成 foreach（$ itemCharacteristics as $ itemCharacteristic） { $ id = $ itemCharacteristic ['ItemCharacteristic ']['ID']; $ icon_name = $ itemCharacteristic ['ItemCharacteristic'] ['icon_name']; //或在任何位置获得图标路径 $ img = $ this-> Html-> image（$ icon_name）; $ itemCharacteristicName = $ itemCharacteristic ['ItemCharacteristic'] ['name']; //与以上相同} Cane Somebody give me an ideas on this Please!I Generate multiple checkboxes from a table that is related with another table with HABTM relationship association. I would like to generate multiple checkboxes with an image along with the text in the label.My two tables are items and items_characteristics. So an Item HasAndBelongToMany characteristics, and an ItemCharacteristic HasAndBelongToMany Items. echo $this->Form->input('Item.ItemCharacteristic',array( 'label' =>false, 'type'=>'select', 'multiple'=>'checkbox', 'options' => $itemCharacteristics , 'selected' => $this->Html->value('ItemCharacteristic.ItemCharacteristic')));This code generate the list of the checkboxes properly and works perfect:This is what i have:Which is generated from DB from the table items_characteristics.And this is what i wanna have:Does Anyone have any Idea how i can achieve this Please? 解决方案 I assume that in your controller you did something like:$this->request->data = $this->Item->find('first', ... ); so that $data contains the information about selected characteristics in form of a subarray,edit: I also assume that Item habtm ItemCharacteristicthen in your view$checked_characteristics = Hash::extract($this->data, 'ItemCharacteristic.{n}.id');foreach($itemCharacteristics as $id => $itemCharacteristic ){ $checked = in_array($id, $checked_characteristics ); $img = $this->Html->image('cake.icon.png'); // put here the name // of the icon you want to show // based on the charateristic // you are displayng echo $this->Form->input( 'ItemCharacteristic.ItemCharacteristic.', array( 'between' => $img, 'label' => $itemCharacteristic, 'value' => $id, 'type' => 'checkbox', 'checked' => $checked ) );}edit: from your comment I understand that $itemCharacteristics come from a find('list') statement.change it into a find('all', array('recursive' => -1));now your code becomesforeach($itemCharacteristics as $itemCharacteristic ){ $id = $itemCharacteristic['ItemCharacteristic']['id']; $icon_name = $itemCharacteristic['ItemCharacteristic']['icon_name']; //or wherever you get your icon path $img = $this->Html->image($icon_name); $itemCharacteristicName = $itemCharacteristic['ItemCharacteristic']['name']; // same as above} 这篇关于在HABTM复选框旁边显示图像的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
