[英]HTML form with checkbox for multiple value
我在 html 输入表单中有一个复选框字段。 在此值是从另一个表中获取的。我想在此复选框的帮助下 select 多个用户。我的代码有什么问题
<div class="form-group col-md-6">
<label> Supervised BY( At IUAC)<span style="color:red;">*</span></label>
<input type="checkbox" name="user" > <br>
<checkbox value=""> </checkbox>
<?php
$sql = "SELECT * from tblstaff ";
$query = $dbh -> prepare($sql);
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=1;
if($query->rowCount() > 0)
{
foreach($results as $result)
{ ?>
<option value="<?php echo htmlentities($result->id);?>"><?php echo htmlentities($result->name);?></option>
<?php }} ?>
我试过这段代码但它没有显示复选框
使用输入类型Checkbox字段像这样
<?php
foreach($results as $result)
{ ?>
<input type="checkbox" name="<?php echo $result->name; ?>" value="<?php echo $result->name; ?>"> <?php echo $result->name; ?> </br>
<?php } ?>
正确代码：
<div class="form-group col-md-6">
<label> Supervised BY( At IUAC)<span style="color:red;">*</span></label>
<?php
$sql = "SELECT * from tblstaff ";
$query = $dbh -> prepare($sql);
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=1;
if($query->rowCount() > 0)
{
foreach($results as $result)
{
?>
<input type="checkbox" name="user" value="<?php echo htmlentities($result->id);?>"><?php echo htmlentities($result->name);?><br>
<?php
}}
?>
编辑：尝试使用<select>的multiple属性
<?php
$sql = "SELECT * from tblstaff ";
$query = $dbh -> prepare($sql);
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=1;
if($query->rowCount() > 0)
{
echo "<select name='user' multiple>";
foreach($results as $result)
{
?>
<option value="<?php echo htmlentities($result->id);?>"><?php echo htmlentities($result->name);?></option>
<?php
}
echo "</select>";
}
?>
您可以像这样使用bootstrap-multiselect
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Dropdown Multi Select</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" type="text/css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-multiselect/0.9.12/css/bootstrap-multiselect.css" type="text/css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script type="text/javascript" src="https://maxcdn.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-multiselect/0.9.15/js/bootstrap-multiselect.js"></script>
</head>
<body>
<form id="formone">
<div style="padding:20px">
<select id="chkone" multiple="multiple">
<?php
$sql = "SELECT * from tblstaff ";
$query = $dbh -> prepare($sql);
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=1;
if($query->rowCount() > 0)
{
foreach($results as $result)
{ ?>
<option value="<?php echo htmlentities($result->id);?>"><?php echo htmlentities($result->name);?></option>
<?php }} ?>
</select>
</div>
</form>
</body>
<script type="text/javascript">
$(function() {
$('#chkone').multiselect({
includeSelectAllOption: true
});
});
</script>
</html>
试试这个
<div class="form-group col-md-6">
<label> Supervised BY( At IUAC)<span style="color:red;">*</span></label>
<?php
$sql = "SELECT * from tblstaff ";
$query = $dbh -> prepare($sql);
$query->execute();
$results=$query->fetchAll(PDO::FETCH_OBJ);
$cnt=1;
if($query->rowCount() > 0)
{
foreach($results as $result)
{ ?>
<input type="checkbox" name="user[]" value="<?php echo htmlentities($result->id);?>" ><?php echo htmlentities($result->name);?>
<?php }} ?>
当您提交表单时，您将获得 $_POST['user'] 作为已检查的用户 ID 数组。
反转提交时的复选框：仅在未选中复选框的情况下设置HTML表单值
[英]Invert checkbox on submit: Set HTML form value only if checkbox is unchecked
HTML复选框，多个具有相同的“名称”。 如果选中，则值为1，如果未选中，则值为0
[英]Html Checkbox, multiple with same 'name'. Value 1 if checked, Value 0 if not checked
当表单中有多个复选框时，HTML复选框验证会中断
[英]HTML checkbox validation breaks when there are multiple checkboxes in the form
Javascript document.getElementById function 未将复选框值返回到 HTML 表单
[英]Javascript document.getElementById function not returning checkbox value to HTML form
使用AJAX，PHP和MYSQL在另一个复选框中显示html表单复选框中的多个值
