[RESOLVED] URL possibilities

[bluetonic]

I have a page for member that forget his/her password. When they input the email address, they receive an email with a new, temp password. What I would like to do is something like this:

from email:
http://domain.com/changepw.php?member_email=[e-mail]

code from changepw.php:
   <tr>
    <td width="197" height="34" class="right">Enter Email: </td>
    <td width="209"><input type="text" name="<?php echo($_GET['member_email']); ?>" id="email" /></td>
  </tr>

Obviously, I can't get it work. However, is it possible to autofill a portion of a form from a link with actually submitting an action?

You want the name attribute to be value

i.e.

<input type="text" name="member_email" value="<?php echo($_GET['member_email']); ?>" id="email" />

I added <input type="text" name="member_email" value="<?php echo($_GET['member_email']); ?>" id="email" /> to my code and get this error:
Notice: Undefined index: member_email in /Applications/MAMP/htdocs/changepw.php on line 136.

to get around this on another page, I used this style of code:
value="<?php if (!empty($member_email)) echo ($member_email); ?>"

Can you explain why the first code doesn't work?

[Kudose]

You get the error because member_email is empty (not set ... undefined) when you run the page.

In the code you posted, you assume register globals is On and it is deprecated.

You should use

if(!empty($GET['member_email'])) echo $GET['member_email'];

[bluetonic]

That means that Globals are turned off in my php.ini file?

If you can access $member_email as if it were $_GET['member_email'] without declaring it as so means your register_globals setting is On
