PHP form

ok ive done a simple form which posts to
<?php echo $_SERVER['PHP_SELF'];?>">

ok when the page gets refreshed after the submit button has been pressed it then resends the data again, how can i stop it from resending the data once the page is resent ??

 

Have a look here and see if it helps you.

 

ermm didnt see anything in there that wld help, i just wnt it so if the page is refreshed the data doesnt get resent.

 

So the data is from the form? In the form, add a hidden input:

<input type="hidden" name="dataResend" />

Code (markup):

For PHP

<?
if{!ISSET($_POST['dataResend'])){

//Add code here for when the page is refreshed

}
else{

//Add Code here for when the form is sent.
//Refresh the page, clearing all data:
header("Location: ".$_SERVER['PHP_SELF']."");

}
?>

PHP:

 

Check with this code:

<?php
if(isset($_POST['resend']) && $_POST['resend'] == $_COOKIE['resendvalue'])
{
echo 'do insert';
setcookie('resendvalue','',time()-1000,'/');
}
$resendval = time();
setcookie('resendvalue',$resendval,time()+1000,'/');
?>

PHP:

<form method="post">
<input type="text" name="mytest">
<input type="submit" value="ok">
<input type="hidden" name="resend" value="<?php echo $resendval;?>">
</form>
