我已经使用下面的代码来为选中的复选框选择多个值,以便将其从数据库表中删除,但是当我是print_r时,它仅显示其不显示id值的键。如何获取php中的多个复选框的值
我使用此代码在数组中获取价值: -
<?php
echo "Hiiiiiiiiii";
include("conn.php");
$sql="select * from test ";
$res=mysql_query($sql) or die(mysql_error());
?>
<form name="form1" method="POST" action="">
<table width="578" border="1" align="center" id="menu">
<tr>
<th></th>
<th>id</th>
<th>Name</th>
<th>email</th>
<th>phno</th>
</tr>
<?php
while($row=mysql_fetch_array($res))
{
?>
<tr>
<td><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td>
<td><?php echo $row['id'];?></td>
<td><?php echo $row['name'];?></td>
<td><?php echo $row['emailid'];?></td>
<td><?php echo $row['phno'];?></td>
<?php
echo"<td><a href='update.php?id=".$row['id']."'>Update</a></td>";
?>
<?php
}
?>
<tr><td><input type="submit" name="delete" value="Delete" id="delete"></td></tr></tr></table>
<?php
// Check if delete button active, start this
$count = mysql_num_rows($res);
echo "$count";
if(isset($_POST['delete']))
{
if(count($_POST['checkbox']) !=0)
{
$array = array("checkbox" => $_POST['checkbox']);
print_r($array);
$ids = implode(',', $array);
echo "$ids";
$result = mysql_query("DELETE FROM test WHERE id IN ($ids)") or die(mysql_error());
}
}
// if successful redirect to delete_multiple.php
if($result)
{
echo "<meta http-equiv=\"refresh\" content=\"0;URL=teach_delinquent.php\">";
echo "SUCCESS";
}
?>
试试'var_dump($ _ POST);'。 – 2012-09-19 06:44:25
你不能有id =“复选框[]”,这需要设置为一个唯一的值。 – jtheman
$ _POST ['checkbox']已经是来自postdata的一个数组,所以你不需要使它变得更安全。 – jtheman
