如何使用GET在php中检索复选框选中的值

Question

I am using Mysql PDO query to fetch the required result and it is saved in and array $newfamily. Now with the help of this array I am implementing check-box with the given code-

<form method="get" action="specific_family.php">
  <?php
    foreach($newfamily as $name)
            {
  ?>
        <input type='checkbox'<?php echo $name;?>"><?php echo $name;?></input>
 <?php
            } 
 ?>
 </select> <input type = "submit" name="submit" >
 </form>

Now in specific_family.php how can I retrieve al the selected check-box values in an array ? Also when I use back button of browser I can see previously selected values as ticked. How can I remove this ?

Please guide.

If you add the name attribute to your input thus:

 <form method="get" action="specific_family.php">
  <?php
    foreach($newfamily as $name)
            {
  ?>
                <label for="<?php echo $name?>"><?php echo $name?></label>
                <input type='checkbox' name="<?php echo $name;?>" id="<?php echo $name;?>"></input>
 <?php
            } 
 ?>
 </select> <input type = "submit" name="submit" >
 </form>

then your checkboxes will show up by name in your $_GET array.

Hope that helps :)
