我有一个问题,我需要在表单提交上循环复选框的数量。循环的Foreach复选框我需要然后将数据插入数据库。 我将如何循环遍历通过表单提交传递的复选框数量?
我的代码如下:
形式:
<form action="createChallenge.php" method="post" name="chalCreate">
Challenge Name:<input type="text" name="chalName" />
<br />
Challenge Target:<input type="text" name="chalTarget"/>
<br />
End Date:<input type="text" name="chalDate">
<br />
<!-- Needs a jquery datepicker -->
Select Friends: <br />
<?php
$selFriend = $conn->prepare("SELECT * FROM Friends WHERE UserID = '$userID' AND Friend = 'y' ORDER BY FriendName ASC");
$selFriend->execute();
foreach($selFriend as $row){
?>
<input type="checkbox" name="test" value="<?php echo $row['FriendID'] ?>"><?php echo $row['FriendName'] ?><br>
<?php
}
?>
<br />
<button type="submit">Create Challenge</button>
</form>
PHP来处理表单:
<?php
if(isset($_POST['test']))
{
$i = 0;
foreach($_POST['test'] as $checked)
{
echo $friend = $checked;
$i++;
}
echo $name = $_POST['chalName'];
echo $target = $_POST['chalTarget'];
echo $date = $_POST['chalDate'];
echo $friend = $_POST['test'];
echo $setby = $_COOKIE['userID'];
$create = $conn->prepare("INSERT INTO Challenge ( chalSetBy, chalName, chalTarget, chalDate ) VALUES ('$setby', '$name', '$target', '$date') ");
$create->execute();
if($create)
{
echo "Challenge made successfully";
}
else
{
echo "There was a problem";
}
}
?>
我认为执行以下操作会回显数据,但事实并非如此,它只选择了最后一个复选框:
$i = 0;
foreach($_POST['test'] as $checked)
{
echo $friend = $checked;
$i++;
}
答案 0 :(得分:1)
在HTML页面中创建一个复选框数组,如下所示,
<form name="frm" method="post">
<input type="checkbox" value="1" name="test[]">
<input type="checkbox" value="2" name="test[]">
<input type="checkbox" value="3" name="test[]">
<input type="checkbox" value="4" name="test[]">
<input type="checkbox" value="5" name="test[]">
<input type="checkbox" value="6" name="test[]">
<input type="submit">
</form>
<?php
foreach($_POST['test'] as $key=>$value)
{
echo $value."<br>";
}
