sending variables through a URL

[Anon]

Hi, i am doing a project for my software engineering class where we are making a computerized form system. what we need to do is when a submit button is pressed we need to email a specific person and in that email will be a link that will send them to the same form that was just filled out. the form should show all the info that was filled out previously. this info is stored in a DB that we created. the only problem that we are having problems setting up a link that will send them to the page and then fill in the fields that were prevoiusly filled in. so i guess my question is. how do you send variables through a link? thanks Luke

To send variables through a link it will be in the format of http://url?variablename=value seperated by &'s

Hope that helps!

yeah that help but i have one more question. how do we access those variables. we have to put the values form fields.

when u send variables in a url to a php script...
eg(http://www.domain.com/script.php?user=bob)
... the variables are accessed in the script as any variable is. For example the following code would print the user value to the screen.
<?
echo $user;
?>

hope you understand now.
if not just post another message and i will be happy to help.

Or more specific for your case. You would enter this for a text field for example if your url was (http://www.domain.com/script.php?user=bob):

<form method=post action="./script.php">
<input type=text size=20 value=$bob>
<input type=submit name=submit>
</form>

Hope that helps clear it up a little more.

Or even better if you want to keep the name of the string the same...

<form method=post action="./script.php">
<input type=text name=user size=20 value=$bob>
<input type=submit name=submit>
</form>
