help with i/o in text files, please

[DementedGimp]

I have a form calling below php snippet, and all it does is echo ".dat" on a blank page... what gives?

<?php
$username = $_POST[$uname];
$fname = $username . ".dat";
if (!file_exists($fname)) { //uniqueness
    chdir('data');
    copy('blank.dat',$fname);
    $handle = fopen($fnname,"a");
    fwrite($handle, $_POST[$password]);
    chdir('..');
    echo $fname;
}    
else {
echo "not unique";
}
?>

Heya, DementedGimp. Welcome to TSDN!

Looks like it's not picking up $_POST[$uname]. Did you mean:

$username = $_POST['uname']

?

[DementedGimp]

Tried that... still nothing... using Apache 1.3 & php 5

Heya, DementedGimp.

The problem is that $username has no value. Try putting this at the top to see what is being submitted with the form:

print_r($_POST);

pbmods,
all I get is ;Array()' as output!

Heya, DementedGimp.

So $_POST is empty; therefore $_POST['uname'] has no value.

pbmods,
here is the calling form:

<?php
echo "Input user info:<br>";
echo "<form method='POST' action='infoinput.php'>";
echo "<br>Please enter username: <input type='text' name='$uname'>";
echo "<br>Please enter password: <input type='text' name='$password'>";
echo "<input type='submit'>";
echo "</form>";
?>

It doesn't see $uname, i guess.....

pbmods,
here is the calling form:
<?php
echo "Input user info:<br>";
echo "<form method='POST' action='infoinput.php'>";
echo "<br>Please enter username: <input type='text' name='$uname'>";
echo "<br>Please enter password: <input type='text' name='$password'>";
echo "<input type='submit'>";
echo "</form>";
?>

It doesn't see $uname, i guess.....

Why use a variable as the name of the input?

Take away the dollar sign and then $_GET['uname'] and the same for password.

pbmods,
I striipped all the php out of the calling form, and it works... thanks pbmods

[DementedGimp]

Arrrgh, pb, it worked for two input variables, but when I added more input vars:
Input user info:[php]
<br>
<form name="userinput" method="POST" action="infoinput.php">
<br>Please enter username: <input type="text" name"$username">
<br>Please enter last name: <input type="text" name="$lastname">
<br>Please enter first name: <input type="text" name="$firstname">
<br>Please enter sex: <input type="text" name="$sex">
<br>Please enter date of birth: <input type="text" name="$dob">
<br>Please enter password: <input type="text" name="$password">
<br>Please enter address1: <input type="text" name="$address1">
<br>Please enter address2: <input type="text" name="$address2">
<br>Please enter city: <input type="text" name="$city">
<br>Please enter statte: <input type="text" name="$state">
<br>Please enter zipcode: <input type="text" name="$zipcode">
<input type="submit">
</form>
[/php]
it didn't see $username, but saw the rest. here is infoiinput.php:
[php]
<?php
print_r($_POST);
$uname = $_POST['$username'];
$pw = $_POST['$password'];
$fname = $uname . ".dat";
if (!file_exists($fname)) { //uniqueness
chdir('data');
copy('blank.dat',$fname);
$handle = fopen($fname,"a");
fputs($handle, $pw);
chdir('..');
// echo $fname;
}
else {
echo "not unique";
}
?>
[/php]
I know, you're going to ask why not mysql, but mysql just refuses to work for me.

Heya, DementedGimp.

Please use CODE tags when posting source code:

[CODE=php]
PHP code goes here.
[/CODE]

Have a look at this page.

PB,
I stripped the $ from the code, but it still does not see 'username'.... here the code:

Input user info:<br>
<form name="userinput" method="POST" action="infoinput.php">
<br>Please enter username: <input type="text" name"username">
<br>Please enter last name: <input type="text" name="lastname">
<br>Please enter first name: <input type="text" name="firstname">
<br>Please enter sex: <input type="text" name="sex">
<br>Please enter date of birth: <input type="text" name="dob">
<br>Please enter password: <input type="text" name="password">
<br>Please enter address1: <input type="text" name="address1">
<br>Please enter address2: <input type="text" name="address2">
<br>Please enter city: <input type="text" name="city">
<br>Please enter statte: <input type="text" name="state">
<br>Please enter zipcode: <input type="text" name="zipcode">
<input type="submit">
</form>
 

here's the code for infoinput.php:

<?php
print_r($_POST);
$uname = $_POST['username'];
$pw = $_POST['password'];
$fname = $uname . ".dat";
if (!file_exists($fname)) { //uniqueness
    chdir('data');
    copy('blank.dat',$fname);
    $handle = fopen($fname,"a");
    fputs($handle, $pw);
    chdir('..');
}   
else {
echo "not unique";
}
?>

Heya, DementedGimp.

What is the output of print_r($_POST) when you submit the form?

[DementedGimp]

Pb,
Everything but the first variable username, which is weird, 'cause it worked with just 2 variables.....

[DementedGimp]

Array ( [lastname] => jacques [firstname] => pages [sex] => m [dob] => 9/28/64 [password] => miki69 [address1] => dddddddddd [address2] => ssssssss [city] => ggggggg [state] => rii [zipcode] => 02842 )
