can't get 'php_self' to work

csxpcm

hello everyone,
I'm stuck with this problem, i got the example from a book, and ive tried for ages to get it to work, but just can't figure where im going wrong. I have a simple form where the user enters a user and email and this gets passed back via php_self. In the section where it should get posted back to the page, i have a print statement to help determine when it does work. However, I just cant get it to enter this section of the code. Any ideas anyone?

Any suggestions are very much appreciated.
Thanks in advance!!!

<html>
<head>
<title>Add new author</title>
</head>
<body>

<?php
if ($submit):
print("hello, we are in the database section");

// database stuff.
?>

<p><a href="<?php echo ($php_self); ?>">
add another author</a></p>

<?php
else: // allow the user to enter a new author
?>

<form action="<?php echo ($php_self); ?>" method=post>
<p>enter the new author: <br>
Name: <input type=text name="name" size=20 maxlength=100><br>
email: <input type=text name="email" size=20 maxlength=100><br>

Two things: I never use PHP SELF, so, when the form is processed by your browser, view the source and make sure the form tag is outputted as

Also, try changing

if ($submit):

if (isset($submit)):

or if register globals is off (which is a safe assumption to make)

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

or even

if ($_POST['submit']):

Hope this helps.

thanx cgraz for the suggestions, but it didnt work. One observation I did make though was upon viewing the source I got:
i.e. the form action = ""

anyone got any ideas?

<html>
<head>
<title>Add new author</title>
</head>
<body>

<form action="" method=post>
<p>enter the new author: <br>
Name: <input type=text name="name" size=20 maxlength=100><br>
email: <input type=text name="email" size=20 maxlength=100><br>

If you have register_globals on, then PHP_SELF should be all capital, not in lowe case. It should be $PHP_SELF.

If you don't have register_globals on, then try $HTTP_SERVER_VARS['PHP_SELF'] or $_SERVER['PHP_SELF']

thanx for the help guys, i now have

which I think suggests PHP_SELF is working ok, and I have global variables on?? Is that right?

Anyway, getting back to my original post, I still cant get the page to enter the section of code, whereby the test

if ($submit):

is checked. But I cant see any problems with

at the bottom of the form. Am I missing something more obvious?

i tried chagnging

if ($submit) :

if (isset($submit)):
if (isset($POST['submit']):
if ($POST['submit']):

as suggested in one of the posts, but still no joy.

p.s. - is there a php command to help me determine if the global variables are on, and other settings?

any other suggestions anyone.
Thanks for all the help up to now everyone!!

<html><head><title>Add new author</title>
</head><body>

<form action="/newauthor.php" method=post>
<p>enter the new author: <br>
Name: <input type=text name="name" size=20 maxlength=100><br>
email: <input type=text name="email" size=20 maxlength=100><br>

Well, we won't know if you have register_globals on unless you tell us which solution you used 🙂

To see which settings you have, put this in a new script:
<? phpinfo(); ?>

Then call that script through the browser and you'll get all the settings.

Back to your original post: I wouldn't suggest testing for the variable $submit, because there are instances where $submit won't be defined (e.g. when you press ENTER in IE, it will submit the form automatically and $submit won't be defined because it wasn't clicked). So try

if (isset($name))

if (isset($HTTP_POST_VARS['name']))

if (isset($_POST['name']))

You have, no doubt, caught it by now, but one of the reasons your submit issue came up was a spelling error. Your code:

<form action="" method=post>
<p>enter the new author: <br>
Name: <input type=text name="name" size=20 maxlength=100><br>
email: <input type=text name="email" size=20 maxlength=100><br>
<input type=SUBMIT name="sumbit" value="submit" </p>
</form>

Note that on the next to last line: name="sumbit"

s/b: name="submit"

I'm working with the same book and same code to develop a db maintenace app. You are a bit ahead of me but the discussion was good for me, also.
