[英]How to get individual values from multiple checkbox dynamically using php?
I am trying to get the individual values from the checkbox , $mail_aspects['active']
and $mail_aspects['aspect_id']
. 我试图从复选框 $mail_aspects['active']
和$mail_aspects['aspect_id']
获取单个值。
But using the below code, I am only able to get the values whose $mail_aspects['active']=1
. 但是使用下面的代码,我只能获得$mail_aspects['active']=1
。 But I need to get both checked and unchecked values to update in DB. 但是我需要获取选中和未选中的值以在数据库中进行更新。
Can anyone help on this issue? 有人可以帮忙吗?
<form method='post' style='display: inline-block;'>
<div class="col-md-12">
<?foreach ($customer['mail_aspects'] as $mail_aspects)
{ ?>
<table>
<tr>
<td>
<label>
<input type="checkbox" name="mail_aspects[]" <?=($mail_aspects['active'] == '1') ? 'checked' : ''?>
value="<?=$mail_aspects['active']?>,<?=$mail_aspects['aspects_id']?>">
<?=$mail_aspects['aspects_name']?>
</label>
</td>
</tr>
</table>
<? }?>
</div>
<button type='submit' name='submit' value='Submit'>Save Aspects</button>
</form>
Using PHP 使用PHP
if(isset($_POST['submit'])){
$mail_aspectsdet=$_POST['mail_aspects'];
for($i=0;$i<count($mail_aspectsdet);$i++)
{
$exp=explode(',',$mail_aspectsdet[$i]);//Explode id and name
$stmt=$db->exec("UPDATE customer_preferences set active=$exp[0] where customer_id=$customerID and aspects_id=$exp[1]");
}
}
To receive unchecked checkbox values in $_POST you have to add a hidden input field with same name and null value before adding the checkbox. 要在$ _POST中接收未选中的复选框值,必须在添加复选框之前添加具有相同名称和空值的隐藏输入字段。 If a checkbox is unchecked the null value of hidden input will be submitted otherwise the value of the checkbox. 如果未选中该复选框,则将提交隐藏输入的空值,否则将提交该复选框的值。
In your case it should look like: 在您的情况下,它应类似于:
<form method='post' style='display: inline-block;'>
<div class="col-md-12">
<?foreach ($customer['mail_aspects'] as $mail_aspects)
{ ?>
<table>
<tr>
<td>
<label>
<input type="hidden" name="mail_aspects[<?=$mail_aspects['aspects_id']?>]" value="0" />
<input type="checkbox" name="mail_aspects[<?=$mail_aspects['aspects_id']?>]" <?=($mail_aspects['active'] == '1') ? 'checked' : ''?>
value="1">
<?=$mail_aspects['aspects_name']?>
</label>
</td>
</tr>
</table>
<? }?>
</div>
<button type='submit' name='submit' value='Submit'>Save Aspects</button>
</form>
Important is that the names of the hidden and the checkbox input are identically. 重要的是,隐藏和复选框输入的名称是相同的。
