[mfaisalwarraich]

hi everybody,

I am trying to get the values in a form if back button of browser is used.

here is the code that im using:

 echo('
    <table cellpadding="3" cellspacing="2" border="1" width="75%" align="center">
    <form method="post" action="home.php">
 
    <tr>
    <td>CID No.</td><td><input type="text" name="cid" value="<?php echo $cid; ?>" /></td>
    </tr>
</form></table>');

i want to print here the value of the variable $cid what was posted by the form but it is not happening. please tell me how i can achieve this. thank you.

When that form is submitted your value should be in $_POST['cid'] in home.php page.

My I suggest some PHP tutorials. w3cschools.org is a great site to start. Google can help.

the general escape character is the backslash, though it only works in parsed strings.

Probably you can take form data into $cid=$_POST["cid"]

and do the string operation on $cid.

For this refer PHP docs.
