Retain checkbox value

[tinko]

My question is that first i need to create the checkboxes which i have already done and then when i set the value of any of the checkboxes as checked, it should be saved in a session after clicking on the submit button and after refresh page also.. so that next user could see the selected checkbox

<?php
if(isset($_POST['checkboxname'])) {[INDENT]$_SESSION['checkboxvalues'] = json_encode($_POST['checkboxname');[/INDENT]
}

else if(isset($_SESSION['checkboxvalues'])) {[INDENT]$checkboxValues = json_decode($_SESSION['checkboxvalues']);[/INDENT][INDENT]foreach($checkboxValues as $value) {[/INDENT][INDENT][INDENT]//iterate through, echoing checkboxes and setting checked to "checked" based on whether the array is checked[/INDENT][/INDENT][INDENT]}[/INDENT]
}

else {[INDENT]//display fresh checkboxes[/INDENT]
}
?>
