Passing variables in PHP4

[Anon]

Hi,

I think I need some help here... after installing PHP4 my forms won't pass variables anymore.

Here is a sample code I used to check it:

<FORM ACTION="test2.php" METHOD="post">
<INPUT TYPE="TEXT" NAME="name" VALUE="">
<INPUT TYPE="PASSWORD" NAME="pass" VALUE="">
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Create Your Account"> </FORM>

In test2.php I use this to check the variables content:

echo ”<br>PASS:$pass”;

...and nothing has been submitted...

isset responds that $pass has not been set.

If anyone has any idea, please respond!

Thanks..

its because your declaring the value of the text fields to be " " (i.e. Null) in all casses, even if you type the text and submit, the argument you got in <INPUT> tag is over writing your typed text.

Just simply remove the VALUE="" from the text fields that you are using to type in from the webpage. in other words, remove the VALUE from ID & passwd fields.

Thanks for your suggestion Daarius,
but it didn't work either... I've tried several variations with the VALUE ... but nothing...

In the code underneath name is without any initial value, while pass has "NewYork". When I submit test2.php reports that there aren't any variables called $name or $pass. I.e. they aren't even set... It's not just that they're empty...

<FORM ACTION="test2.php" METHOD="post">
<INPUT TYPE="TEXT" NAME="name">
<INPUT TYPE="PASSWORD" NAME="pass" VALUE="NewYork">
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Create Your Account">
</FORM>

If you have any other suggestions please post them... this is kind of driving me crazy...

Ah, I ran into this problem the first time I worked with forms and PHP. The trick is to remember everything you pass to the script then becomes a valid variable.

<?php
if ($submit) {
// here's where you'd put what you want
// the script to do with their input
echo "My name is $name<BR>";
echo "And my password is $password";
} else {
<FORM METHOD='POST' ACTION='$PHP_SELF'>
<INPUT TYPE='text' NAME='name'>
<INPUT TYPE='password' NAME='password'>
<INPUT TYPE='Submit' NAME='submit' VALUE='Create account'>
</FORM>
}
?>

Hope that helps!

D'oh... and don't forget the echo or print statements for the form...

<?php
if ($submit) {
// here's where you'd put what you want
// the script to do with their input
echo "My name is $name<BR>";
echo "And my password is $password";
} else {
echo "<FORM METHOD='POST' ACTION='$PHP_SELF'>";
echo "<INPUT TYPE='text' NAME='name'>";
echo "<INPUT TYPE='password' NAME='password'>";
echo "<INPUT TYPE='Submit' NAME='submit' VALUE='Create account'>";
echo "</FORM>";
}
?>

Thanks Dave,

but again... it doesn't work... the form doesn't pass the variables (or the php doesn't accept them)...

When executing your example the $submit variable is not set (even though I press the submit-button in the form), and therefore nothing within the if-statement is executed...

Thanks for answering though... maybe i'd better remove php4 and install it from scratch..

Add a phpinfo(); to the bottom of the page you are passing the variables to.

Down near the bottom of the phpinfo display, it will list out any arguments that were passed into the page.

I know it's not an answer but it might help you troubleshoot what's going on.

Are you running Win32 or Linux/Unix version of PHP4 and on which webserver? (Just nice to know if you do get this figured out)

Try with Get method and see if that works first, then if it does you will at least know its to do with the POST. I doubt POST is case sensitive is it?

Thanks to all of those trying to help me!

For those who encounter the same problem I thought I'd post the solution here:

In the php.ini under "Data Handling" register_globals have to be turned On, like
"register_globals = On;"

The default was Off, and then the variables weren't passed from any forms.

I'm using the win32 version on a win98 platform.

THANK YOU!! I thought I was going insane too.

This is an extremely important find. I normally don't use PHP on Win platforms and this was driving me nuts. Why they defaulted that to off for the Windows version I don't understand. Its not that way for Unix.
