Form Question

Anyaer

I'm trying to implement a simple form. I've pretty much been using the format in the PHP book I bought, but everytime I submit this form, it just reloads the form again.

<p>Music Lab Login</p>
<form action="<Full URL of this file>" method="post">
<p>Username:<br />
<input type="text" name="username" size="20" maxlength="20" value="" /></p>
<p>Password:<br />
<input type="password" name="pw" size="20" maxlxength="20" value="" /></p>
<input type="submit" name="submit" value="Login" />
</form>

<?php

if(isset($_POST['submit'])) {
echo "Got it";
}

have you made sure php is properly installed on the machine you are trying to test it with? after you submit the form try to view the source and see if the php code shows up or isnt there.

Anyaer

The page is hosted by HostSave.com, so I dunno if I can do anything about the installation. For what it's worth, however, I've already done some PHP code on this same site, retrieving and inserting values from a MySQL database.

i dont think a submit button itself will turn up in your $_POST array. i usually put a hidden field in my forms and check that for submission.

add this to your form;
<input type="hidden" name="submitted" value="true">

then change your code too;

if (isset($_POST['submitted'])) { 
  echo "Got it";
}

No dice on that one either, unfortunately. Is it my action field or something? I've got it set to the absolute URL of the file, i.e http://www.blah.com/Test/formTest.php.

The submit button WILL show up, you do not need a hidden field.
You can include one if you like but its not necessary.

Anyaer is the code you posted exactly as you have it in your php file? If so I noticed

<p>Password:<br />

maybe take out the / and just have <br>..

thorpe

a <br> tag is no good if you want to be xhtml complient, which this code looks to be.

i cant see why its not working. can you post a link to this form page?

i dont know what to tell you...i copied the code as is, only changed the post url and it worked fine. i saw got it when i posted the form. so it seems more to be a problem with the server and not the code.

Type anything in the fields, nothing in the code now is doing any checking or anything with it.

i see the problem. it is php version 4.0.6. $_POST didnt exist then. use $HTTP_POST_VARS instead.

Anyaer

Eureka! Thanks a lot. I was totally lost on that.

Does this mean that the $_GET global doesn't exist either? Is 4.0.6 a pretty outdated version then (not that I really have control over them updating).

drew010

yeah $_GET wont exist either, for that its $HTTP_GET_VARS.

also note you will need to use:
$HTTP_SERVER_VARS for $SERVER
$HTTP_COOKIE_VARS for $COOKIE
$HTTP_ENV_VARS for $ENV
$HTTP_POST_FILES for $FILES
$HTTP_SESSION_VARS for $_SESSION

yeah 4.0.6 is pretty old, they are at 4.3.11 now. I think 4.0.6 came out 23-Jun-2001

Thanks again. I copied down this list to keep around.
