<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 }} ?>

I tried this code bu it is not showing the check box我试过这段代码但它没有显示复选框

Answer 1

Use input type Checkbox field Like this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 } ?>

Answer 2

<input type="checkbox">

Correct code: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
}}
  ?>

Edit : Try with multiple attribute of <select>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>";
}
?>

You can use bootstrap-multiselect Like This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>

Answer 4

Just Try this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 }} ?>

when you will submit the form, you will get $_POST['user'] as an array of user ids's that are checked.当您提交表单时，您将获得 $_POST['user'] 作为已检查的用户 ID 数组。
