（编辑以提供更清晰的示例）我有文档->节->变量的cakephp模型结构
在一个表单中，我希望能够列出所有变量，但嵌套在文档和节级别中。那一点没问题。
我想要变量级别的每个项目旁边的复选框 - 以允许选择变量。
I want a checkbox at sectionlevel, that when selected will select all the checkboxes for the variables in that section.
我想要在文档级别的复选框，以便选择该文档的变量（即所有部分）。
为了方便起见，我这样命名了复选框（好吧，我已经设置了 ID）（伪代码）：
document level: id = Document id
section level id = Document id_Section id
variable level id = Document id_Section id_Variable_id
我希望如果我选择部分级别复选框，我可以通过在可变级别复选框的所有 id 开头使用 Document id_Section_id 存根来设置该部分的所有可变级别复选框......但也许我正在抓住稻草?
以下是级别中的复选框示例：（为布局道歉）
<?php
//Document level
//all of this within a ForEach loop for documents
echo "<table>";
echo "<tr><td>Collection dates</td><td>".$project_document['data_collection_dates']."</td>";
echo "<td>Select (toggle) all variables"
.$this->Form->checkbox($project_document['id'], // note that this sets the chkbox id to the value of the current document id
array('hiddenField' => false,'onclick'=> 'SelectSection(this,this.name,this.checked);'))
."</td></tr>";
echo "</table>";
foreach ($project_document['ProjectDocumentSection'] as $project_document_section):
echo "<h4>" . $project_document_section['title']. "</h4>";
echo "<table>";
echo "<tr><td>Collection Method</td><td>" . $project_document_section['method']. "</td></tr>";
echo "<tr><td>Collection objective</td><td>" . $project_document_section['objective']. "</td>";
echo "<td>Select (toggle) all section variables"
.$this->Form->checkbox($project_document['id']
."_".$project_document_section['id'] // and here the chkbox id is set to combination of document id and section is (using _ as separator)
, array('hiddenField' => false))."</td></tr>";
echo "</table>";
echo "<table><tr><th>Full text</th><th>Type</th><th>Format</th><th>Codeset</th></tr>" ; // header for variable table
foreach ($project_document_section['ProjectDocumentSectionVariable'] as $project_document_section_var):
echo"<tr><td>".$project_document_section_var['variable_type']
."</td><td>".$project_document_section_var['variable_format']
."</td><td>";
echo "<td>".$this->Form->checkbox($project_document['id']
."_".$project_document_section['id']
."_".$project_document_section_var['id'], array('hiddenField' => false))."</td></tr>";
endforeach;
echo "</table>";
endforeach;
// and later endforeach for the document itself
?>
当渲染时，它可能看起来像这样；
<td>Select (toggle) all variables
<input type="checkbox" name="data[Project][11]" onclick="SelectSection(this,this.name,this.checked);" value="1" id="Project11"/>
// note that checkbox id and name include ref to document id (11)
</td></tr>
<h4>Details of Health Workers at Facility</h4>
<table>
<tr><td>Collection Method</td><td>FW completed evaluation on paper</td></tr>
<tr><td>Collection objective</td><td>blah blah blah blah</td>
<td>Select (toggle) all section variables
<input type="checkbox" name="data[Project][11_24]" value="1" id="Project1124"/></td></tr>
// note that checkbox id and name include ref to document id (11) and section id (24)
</table>
<table>
<tr><th>Full text</th><th>Type</th><th>Format</th><th>Codeset</th></tr>
<tr><td>Site</td><td>Categorical</td><td>Quantative</td>
<td><input type="checkbox" name="data[Project][11_24_402]" value="1" id="Project1124402"/></td></tr>
// note that checkbox id and name include ref to document id (11), section id (24) and variable id (402)
<tr><td>Facility</td><td>Categorical</td><td>Quantative</td>
<td><input type="checkbox" name="data[Project][11_24_403]" value="1" id="Project1124403"/></td></tr>
<tr><td>Name</td><td>Text</td><td>Quantative</td>

<tr><td>Position of Health Worker</td><td>Text</td><td>Quantative</td>
<td><input type="checkbox" name="data[Project][11_24_405]" value="1" id="Project1124405"/></td></tr>
<tr><td>Description</td><td>Text</td><td>Quantative</td>
<td><input type="checkbox" name="data[Project][11_24_406]" value="1" id="Project1124406"/></td></tr>
<tr><td>Interviewer Code</td><td>Categorical</td><td>Quantative</td>
<td><input type="checkbox" name="data[Project][11_24_407]" value="1" id="Project1124407"/></td></tr>
<tr><td>Date of Facility Visit </td><td>Date</td><td>Quantative</td>
<td><input type="checkbox" name="data[Project][11_24_408]" value="1" id="Project1124408"/></td></tr>
</table>
有人对如何解决这个问题有任何建议吗？我敢肯定有不止一种方法可以杀死这只鸟..
谢谢
