从多个复选框行收集 $_POST

我有一个包含多行复选框的表单，每个复选框都有一个特定的 id，使用foreach loop.

你如何抓住$_POST类似的信息？我觉得某种程度上是这样的$_POST[][]，就像一个子数组，但我不知道如何设置它：

foreach($stakholderArray as $currentEntry) {
    print "<tr class='$bgcolor'>";
    print "<td class='left'>$currentEntry[org]</td>";

    if($currentEntry['dataFound']) {  
        //if data was found for current stakeholder, display it
        print ($currentEntry['Partner']) ? '<td><input type ="checkbox" checked ="checked" /></td>' : '<td><input type ="checkbox"  /></td>';
        print ($currentEntry['Agreement']) ? '<td><input type ="checkbox" checked ="checked" /></td>' : '<td><input type ="checkbox"  /></td>';
        print ($currentEntry['Train']) ? '<td><input type ="checkbox" checked ="checked" /></td>'  : '<td><input type ="checkbox"  /></td>';
        print ($currentEntry['Meet'])  ? '<td><input type ="checkbox" checked ="checked" /></td>' : '<td><input type ="checkbox"  /></td>';
    }
    else {  //else...no stakeholder data, display empty columns
        print "<td><input type ='checkbox'/></td><td><input type ='checkbox'/></td><td><input type ='checkbox'/></td><td><input type ='checkbox'/></td><td><input type ='checkbox'/></td>";
        print "</tr>";
    }## Heading ##

和我之前回答过的一个问题有点关系：从 HTML 表单中发布数组，无需使用 javascript

• 将它们封装在表格中
• 给它们一个“数组”名称
• 提交后，它们在发布过程中最终以数组形式出现

相关项目应该是这样的：name="item[collection name][collection name][]"- 请注意与该集合相关的第一个索引（以便于定位），以及空索引意味着该集合中有一个数组（而不是单个值）。所以对于你的复选框：

<input type="checkbox" name="answers[set1][]" value="apple" />   //imagine checked
<input type="checkbox" name="answers[set1][]" value="orange" />  //imagine checked
<input type="checkbox" name="answers[set1][]" value="grape" />
<input type="checkbox" name="answers[set2][]" value="airplane" />   //imagine checked
<input type="checkbox" name="answers[set2][]" value="train" />  //imagine checked
<input type="checkbox" name="answers[set2][]" value="boat" />
<input type="checkbox" name="answers[solo]" value="boar" /> //single type value. note that there is no [] in the end

在请求数组中最终像这样（比如 POST）：

$_POST[] = array(
    'answers' => array(
        'set1' => array('apple','orange'),   //unchecked items won't be included
        'set2' => array('airplane','train'), //unchecked items won't be included
        'solo' => 'boar'
    )
);

<table>
    <?php foreach($stakeholderArray as $stakeholder): ?>
    <tr>

    <?php 

        //declare so these exist regardless of data
        $partner   = '';
        $agreement = '';
        $train     = '';
        $meet      = '';

        //if we have data, mark the boxes accordingly
        if($stakeholder['dataFound']){

            $checked = 'checked ="checked"';

            //mark as checked or blank
            $partner   = ($stakeholder['Partner'])   ? $checked: '';
            $agreement = ($stakeholder['Agreement']) ? $checked: '';
            $train     = ($stakeholder['Train'])     ? $checked: '';
            $meet      = ($stakeholder['Meet'])      ? $checked: '';

        }
    ?>

       <td><input value='partner' name="stake[<?= $stakeholder ?>][partner]" type ="checkbox" <?= $partner ?> /></td>
       <td><input value='agreement' name="stake[<?= $stakeholder ?>][agreement]" type ="checkbox" <?= $agreement ?> /></td>
       <td><input value='train' name="stake[<?= $stakeholder ?>][train]" type ="checkbox" <?= $train ?> /></td>
       <td><input value='meet' name="stake[<?= $stakeholder ?>][meet]" type ="checkbox" <?= $meet ?> /></td>

    </tr>
    <?php endforeach; ?>
</table>

他们最终应该是这样的：

$_POST[] = array(
    'stakeholder1' => array(
        'partner'=> 'partner',
        'agreement'=> 'agreement',
        'train'=> 'train',
        'meet'=> 'meet'
    ),
    'stakeholder2' => array(
        'partner'=> 'partner',
        'agreement'=> 'agreement',
        'train'=> 'train',
        'meet'=> 'meet'
    ),
);
