[php75]

Hi,

     I  want to set the time first and then display  add 1 hour to time after submit the button using html form and php.How can i do this one ?Please help....

There are various functions in PHP for displaying dates/times and doing arithmetic with them.
 
Before you use any of them, make sure you have set your default timezone. You can do this in your php.ini file or by using date-default-timezone-set.

 

The easiest to use is the date function.

<?php 
$timestamp = strtotime($_GET['time_input']) + 60*60;
$time = date('H:i', $timestamp);
echo $time;
?>

$_GET['time_input'] will be the name of your textbox in your form.

<?php 
$timestamp = strtotime($_GET['time_input']) + 60*60;
$time = date('H:i', $timestamp);
echo $time;
?>

$_GET['time_input'] will be the name of your textbox in your form.

 

If the date is coming from a form most people use post for it's more secure, so it would be better to use $_POST['time_input'].  Though to be honest I have I'm still a little confused on the original poster's post and this in what the OP means set the time in the form? Does it want to be incremented one hour before being made a selection in the form (giving the user an option) or be already set?

For what it's worth, it's fairly easy to tamper with POST variables. You could just go into the code inspector for your browser and modify the source code before submitting the form.

@cyberRobot is correct, Post is no more secure than GET.

Sorry, typo - I did mean $_POST
