使用php从复选框中检索数据

Question

i have send the value dynamically from check-box and when i tried to retrieve all the value dynamically using loop, it just goes on loading. my code for sending value from check-box:

while ($row=mysql_fetch_array($query))
{

   $member_id=$row["member_id"];
   <input type='checkbox' name='check' value='$member_id'>
}

// this is working. but when i try to fetch the data from checkbox from only where the tick is given it doesn't work. this is how i tried to fetch the data


while(isset($_POST['check']))
{
   echo $_POST['check']."<br>";

}

Answer 1

The trick here is, when you have multiple checkboxes with the same name and you want to get all the checked values on the server side, then you need to add [] after the name of the checkbox field in the html, eg.

<input type='checkbox' name='check[]' value='$member_id'>

if you do this, then $_POST['check'] will be an array of all the checked elements. As pointed out by others,

while(isset($_POST['check']))

represents an infinite loop. It should be

if(isset($_POST['check']))
foreach($_POST['check'] as $each_check)
 echo $each_check;

And finally, its a duplicate of an existing question. Please search before asking again :)
