I wonder if anyone can help me using session. I have two forms (create.php and modify.php) and I would like to make it one form by using function 'session'.

 

I tried to register the variables before using them but am not sure the way I declare them is correct or not. Please assist.

 

 
<?php

session_start();

//Register our session variables
session_register('id);
session_register('name');
session_register('surname');
session_register('dept');	

//Store our posted values in the session variables
$_SESSION['name'] = $_POST['id'];
$_SESSION['name'] = $_POST['name'];
$_SESSION['surname'] = $_POST['surname'];
$_SESSION['dept'] = $_POST['dept'];
....
....


?>

 

Here are the original code before using 'session' the modify.php is about the same only the SQL query need to be added but I don't know how we can use session so that we only need one form instead of two.

 

I hope someone can help me out.

Thanks.

 

create.php

<?php
    
    $id = "";
    $name = "";
    $surname = "";
    $dept= "";
    
if (isset($_POST['submit'])) {
    
        $id = $_POST['id'];
    $name = $_POST['name'];
    $surname = $_POST['surname'];
    $dept = $_POST['dept'];

            
}
?>
<html ><head></head><body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
  <div align="center">
  <table width="300" border="1">
    <h1> Modifying A User </h1>

      <tr>
        <th scope="row">Name</th>
        <td><input type="text" name="name" value="<?php echo $name;?>" /></td>
      </tr>
    
    <tr>
      <th scope="row">Surname</th>
        <td>
	<input type="text" name="surname" value="<?php echo $surname; ?>" /></td>
      </tr>

<tr>
      <th scope="row">Department</th>
        <td><input type="text" name="dept" value="<?php echo $dept_name; ?>" /></td>
      </tr>    
  
  </table>
  <br/>
  
  <a href="index.php">
<input type="button" name="back" value="Back" /></a>

    <input type="submit" name="submit" value="Modify"/>

  </div>
</form>
</body></html>

It doesn't appear to me that you need to use a session for this.  You can have one form and pass it a value in the link that is clicked to get it to tell whether it is create or modify.  Based on that run a SELECT query or not and create the form with a submit button with a value of either Add or Save.  Then when submitted check which submit was clicked and run the appropriate query, INSERT or UPDATE.

Hi AbraCadaver,

 

The thing is I have almost similar pages for create.php and modify.php and I would like to use SESSION instead of $_GET and $_POST so I can make these two forms into one only..

 

Here are both of the codes: 

modify.php

<?php
//	exit;
require 'includes/application_top.php';	

$name = "";
$surname = "";
$add = "";
$dept= "";
$mobile = "";

if (!isset($_POST['submit'])) 
{

	$q = "SELECT * FROM persons WHERE ID = $_GET[id]";

	$result = mysql_query($q) or die (mysql_error());
	$row = mysql_fetch_array($result);

	$name = $row['name'];
	$surname = $row['surname'];
	$add = $row['address'];
	$dept = $row['dept_id'];
	$mobile = $row['mobile'];
    
	}

if (isset($_POST['submit'])) 
{

	$name = $_POST['name'];
	$surname = $_POST['surname'];
	$add = $_POST['add'];
	$dept = $_POST['dept'];
	$mobile = $_POST['mobile'];

	$errormsg = "";

	if($name == "") 
		$errormsg = $errormsg. "Name<br/ >";

	if ($surname == "") 
		$errormsg = $errormsg. "Surname Please <br/ >";

	if ($mobile != "" && !is_numeric ($mobile))
		$errormsg = $errormsg. "Mobile No? <br/ >";

	 if ($errormsg != "")
		echo "Please fill the blank info: <br/ > $errormsg";

		else 
		{

			$input_field = "";

			foreach ($_POST as $key => $val)
			{

				if ($key != 'submit')
				{
				$input_field.= "<input type = 'hidden' name = '$key' value = '$val'/>";
				}
			}
?>

If you are trying to prevent duplicate form code then I agree with AbraCadaver, sessions will not help you here. His suggestion is spot on. I only wanted to add that Zend_Form in the Zend Framework, specifically the populate method, can also help you achieve what you are looking for.

I see ok, so there is no way I can use 'SESSION' instead of $_POST and $_GET in my form? As I have two almost similar form (create.php and modify.php) I would like to make it only one form call createAndmodify.php using SESSION then go to another confirmation page for these form.

 

I thought we can do that? :confused:
