Hi I'm recenlty studying PHP myself
and I have got a problem in passing variables to one php script from another

i have following code as index.php

Expand|Select|Wrap|Line Numbers

 
<?php

$name=HREEDN

?>

<html>

<head>

<title><?php print ("$name")?> in PHP</title>

<h1><font color=BLUE><center>WELCOME TO HREEDN</center></font></h1>

</head>

<body bgcolor=gold>

<center><table width=80%>

<tr>

<td><a href= index.php><center>Home</center></a></td>

<td><a href= search.php><center>Search Friends</center></a></td>

<td><a href= images.php><center>View Images</center></a></td>

<td><a href= contact.php><center>Contact Me</center></a></td>

</tr>

</table>

</center>

<table width=100%>

<tr>

<td width=50%>

<font size=2 face=arial>

<br>

<P>This site is currently being developed by a novice php programmer

and please help this php programmer by filling the form and commenting.

</P>

<P>

You can send the feedback to [EMAIL REMOVED]<br>

or just use the link above

</P>

</font>

</td>

<td width=50%>

<br/><br/><br/>
 
<form action="confirm.php" method="POST">

<P>

<b>

First Name: <input type="text" NAME="fname"><br/>

Last Name: <input type="text" NAME="lname"><br/>

Age: <input type="text" NAME="age"><br/>

</b>

</P>

<br/>

<input type=submit value="Done">

<input type=reset value="Clear">

</form>

</td>

</tr>

</table>

</body>

</html>

and i have a confirm.php file as

Expand|Select|Wrap|Line Numbers

 
<html>

<head>

<title>Confirm the data</title>

<h1><font color=BLUE><center>WELCOME TO HREEDN</center></font></h1>

</head>

<body bgcolor=gold>

<center><table width=80%>

<tr>

<td><a href= index.php><center>Home</center></a></td>

<td><a href= search.php><center>Search Friends</center></a></td>

<td><a href= images.php><center>View Images</center></a></td>

<td><a href= contact.php><center>Contact Me</center></a></td>

</tr>

</table>

</center>

<?php

printf ("First Name:", $_POST['fname']);

print ("\n<br/>\n");

print ("Last Name: $_POST['lname']");

print ("\n<br/>\n");

print ("Age: $_POST['age']");

print ("\n<br/>\n");

print ("Sem: $_POST['sem']");

?>

</body>

</html>

but when i try filling the form and submit
it shows a blank page
i don't know the reason
but if i use $variable instead of $_POST['variable']
and use GET method it shows a html page without the values in variable

how can i solve this problem
thanks

Hi shreedhan,

Wlecome to TSDN!

Try changing the code a little. I would replace print(....) lines with:

Expand|Select|Wrap|Line Numbers

 
echo 'First Name:' . $_POST['fname'] . '<br />';

echo 'Last Name:' . $_POST['lname'] . '<br />';

echo 'Age:' . $_POST['age'] . '<br />';

echo 'Semester:' . $_POST['sem'] . '<br />';

Give that a try and see how you get on

Also the input type=submit shoud be input type="submit" I think. So load the quotes around it. That's certainly the way I do not.

If none of this works turn on the error handling and see what comes up.

Cheers

Expand|Select|Wrap|Line Numbers

echo 'First Name:' . $_POST['fname'] . '<br />';

echo 'Last Name:' . $_POST['lname'] . '<br />';

echo 'Age:' . $_POST['age'] . '<br />';

echo 'Semester:' . $_POST['sem'] . '<br />';

print() and echo() are the EXACT same thing.

Also the input type=submit shoud be input type="submit" I think. So load the quotes around it.

Quotation marks only make a difference when the name you are using has a space in it. It is also the proper mark up, but it wouldn't be the cause of error in this case.

but when i try filling the form and submit
it shows a blank page
i don't know the reason
but if i use $variable instead of $_POST['variable']
and use GET method it shows a html page without the values in variable

It shows absolutely nothing? Not even the HTML that you already have? Be more descriptive of what you actually see.

And so you know, printf() is not the same as print() and has completely different rules for the way that it works. I'll assume you used it by accident in the first call. Fix it.

I know, I was just suggesting an alternative to get it re-written as I think there may be issues with the way the print function is being used.

Am I correct in thinking that

Expand|Select|Wrap|Line Numbers

print ("Last Name: $_POST['lname']");

should really be:

Expand|Select|Wrap|Line Numbers

print('Last Name: ' . $_POST['lname']);

I guess I was trying to ensure that the original line was re-written in accordance with something I knew for sure worked.

You are correct in stating that arrays should not be entered into the string in that manner, but I'm not sure if that would cause it to no longer work. If he removes the "f" in printf(), and suddenly that line begins to work, then the arrays would be the culprit.

Thanks both of you Volectricity and Nathj
the code is now running as I replaced
print ("Last Name: $_POST['lname']");
with
print ("Last Name:". $_POST['lname']);

and Volectricity I was using printf() function randomly to check if it works

and further when I meant blank page, it showed nothing, not even HTML code i had written.

Anyway, my problem is solved now
Thank you guys again

Yeah, on second thought, I think the only way to put arrays INTO the string is like so:

[php]$str = "foo: {$_POST['foo']}";[/php]

Thanks for your wishes.

I have one more question to ask.
I am getting values of all the variables from index1.php to confirm.php
now can I pass these values from confirm.php to some other.php file
so that I can use them to pass into database?

Thanks
