我有一个包含多个复选框集的表单,其中输入的名称是动态创建的(name =“'。$ name。'[]”)。 HTML结果如下所示:
<tr>
<td><input type="checkbox" name="1[]" value="Jan"/></td>
<td><input type="checkbox" name="1[]" value="Feb"/></td>
</tr>
<tr>
<td><input type="checkbox" name="2[]" value="Jul"/></td>
<td><input type="checkbox" name="2[]" value="Sep"/></td>
<td><input type="checkbox" name="2[]" value="Dec"/></td>
</tr>
<tr>
<td><input type="checkbox" name="3[]" value="May"/></td>
<td><input type="checkbox" name="3[]" value="Aug"/></td>
</tr>
提交后,我知道它是一个多维数组,但是如何使用foreach语句获取输入名称的值?目前,我已经尝试过了,但是它没有给我输入名称的值。
foreach ($_POST as $task){
foreach ($task as $key => $month){
echo '<p>Task ID is: '. $task .' and the month check is '. $month .'';
}
}
哪个返回(如果全部选中):
Task ID is: Array and the month check is Jan
Task ID is: Array and the month check is Feb
Task ID is: Array and the month check is Jul
Task ID is: Array and the month check is Sep
Task ID is: Array and the month check is Dec
Task ID is: Array and the month check is May
Task ID is: Array and the month check is Aug
我需要输入名称作为任务ID:
Task ID is: 1 and the month check is Jan
Task ID is: 1 and the month check is Feb
Task ID is: 2 and the month check is Jul
Task ID is: 2 and the month check is Sep
Task ID is: 2 and the month check is Dec
Task ID is: 3 and the month check is May
Task ID is: 3 and the month check is Aug
非常感谢您提供任何帮助。
您的$ _POST将具有表单帖子名称作为键。因此,您将必须从第一个foreach循环中获取密钥,如下所示:
