i am having some problems posting some values into a form when i click edit. i have checked to make sure that the variables contain the values that i want however they are not posting back to the form.
here is my code below.

if ($_GET['mode'] == 'edit')
{	
	$c=$_GET['id'];
	echo"$c";
	// editing an existing entity
	
	// check for value of id
	/*if (!$_GET['coursecode'])
	{
		echo "error: no coursecode specified, <a href=\"{$_SERVER['PHP_SELF']}\">click here to continue</a>";	
		exit;
	}*/
	
	
	if (!$_POST['submit'])
	{
	
			
					
					
					
					$con = mysql_connect("$hostname","$username","$password");
					if (!$con)
					  {
					  die('Could not connect: ' . mysql_error());
					  }
					  mysql_select_db("$database", $con);
					  
					// $sql= "SELECT  * FROM rules WHERE type='prerequisite' ";
					 //$result=mysql_query($sql);
					 
						
							
				
		// first access to form
		
				// checking if the record is in the database 
				 //$sql= "SELECT  * FROM rules WHERE type='prerequisite' ";
		//$q = "SELECT first_name,last_name,password FROM students WHERE id_no='$c' ";	
		//if ($result=mysql_query($sql))
		
		
			$q = "SELECT first_name,last_name,password FROM students WHERE id_no='$c' ";
	
		
		
		
		if (!$result = mysql_query($q) )
			{
				
				//extract($row);
				//$_POST['id']=$id_no;
				
				
			echo "error: user with id {$_GET['id']} does not exist, <a href=\"{$_SERVER['PHP_SELF']}\">click here to continue							 				</a>";	
			exit;	
			}
			else
			{
			$row = mysql_fetch_array($result, MYSQL_BOTH);
			 
				if (mysql_num_rows($result)!=0) {
					echo "Found Information!";
				}else{

Why are you using both get and post while retrieving the data.

Use $_GET if your form method contains get
OR
Use $_POST if your form method contains post

i am using the get method to get the id from the url and i am using the post method in the form. i am not using the get method in any forms. it is just being used to get the id from the url and the mode of the form (ie new or edit )

0

that is unless you are using the following form action:

<form action="/?mode=edit&id=whatever" method="post">
<!-- enter form fields here -->
</form>

which is completely possible. I do it all the time and it works fine.

i am using the get method to get the id from the url and i am using the post method in the form. i am not using the get method in any forms. it is just being used to get the id from the url and the mode of the form (ie new or edit )

If you want to read anything from the query string, you need to use $_REQUEST

Otherwise follow the procedure as said by OS_dev

if i set the mode to edit then in the instance where the form is accessed for the first time the mode should be new
here is the code that i have thus far for what i am doing

<?php

include('header.php');

	{

		exit;
	}*/
	
	
	if (!$_POST['submit'])
	{
	
			
					$hostname = "localhost";

i am using the get method to get the id from the url and i am using the post method in the form. i am not using the get method in any forms. it is just being used to get the id from the url and the mode of the form (ie new or edit )

You can pass both values with post method also..

you can use hidden type to send id value..like

<input type='hidden' name='<?php echo $id ?>'>

and cn get to second page like

$id = $_POST['id'];
// and othr variables also

$name = $_POST['name'];

or if u want to use only get method then you can use it like this..

<a href='yourpage.php?id=<?php echo $id ?>'>Get ID</a>

in second page just call this id like

$id = $_GET['id'];

and can get another variable like this...

$name = $_POST['name'];

and so on..:)

hope this will help you...

<form action="{$_SERVER['PHP_SELF']}?mode={$_GET['mode']}$id" method="post">

into this line

<form action="{$_SERVER['PHP_SELF']}?mode=$id" method="post">

$id = $_GET;

// other variables like..

First you tell me that now you get value in $id or not ?? i think u got value in $id...

now your ans...:)

Yes..i told u to replace your form tag

<form action="{$_SERVER['PHP_SELF']}?mode={$_GET['mode']}$id" method="post">

with

<form action="{$_SERVER['PHP_SELF']}?mode=$id" method="post">

when u pass any variable through addressbar or link or url u not need to specify the GET method..it will automatically become get method when u pass it through url.

in your form tag u specified the GET method that's why u didnt got any result..in $id...

so just remove that GET method..and it will be working..:)

still have query ??? just ask me again ...:) i m here to help u...:)
