Simple Coding Problem

[westonm]

I am thining this will be pretty simple for someone to help me with, I have been hassling with it for several hours and really feel dumb that I can't get it to work. 

Here is the problem -

I have one script wherein I have a form that passes a variable using Post method. 

I have previously assigned a value "A" to a variable $rtn

the input is:

<input name="Rtn" type="hidden" value="<?php echo $rtn; ?> />

 

In the script that I am calling I first get the value of the variable:

 

$rtn = (_POST['Rtn']);

 

then there is other stuff goin on and I come to an if stmt:

 

if ($rtn == "A" {

  do some stuff

} else {

  echo $rtn;

}

 

It will never get into the do some stuff - it always falls through to the else the output is

\'A\'

 

I have tried to use double quotes, single quotes, used stripslasches and addslashes funtions, trim, and various combination of all of these. 

Nothing I do seem to get me into the first part of the if stmt, to do some stuff.

this

$rtn = (_POST['Rtn']);

 

must be

 

$rtn = $_POST['Rtn'];

 

hope that helps

I can't type very well either - it is actually

$rtn = ($_POST['Rtn'])

Don't type code in; copy and paste it. It's near impossible to diagnose problems when it isn't the actual code.

[cssfreakie]

I can't type very well either - it is actually

$rtn = ($_POST['Rtn'])

 

well if that is the code it's missing a semicolon -> ;

it should be

$rtn = $_POST['Rtn'];

anyway are you sure you even have a $_POST value set?

In your if statement. You are missing a closing parenthesis.

Also. Please use the code tag when inserting code

Ok sorry - Am copying the code;

 

Script 1

<form action="dataProcess.php" method="POST" id="Email">

...

<input name="Rtn" type="hidden" value="<?php echo $rtn; ?>" />

 

Script 2

...

$rtn = ($_POST[Rtn]);

 

...

if ($rtn == "A") {

              header ("Location: http://www.***.com/foundation/MeetBoard.php");

              exit(0);

} else {

                echo "Fall to else ";

                echo $rtn ;

                echo gettype($rtn);

}

 

Output

Fall to else \'A\'string

 

When it works, the else clause will send me off to the home page.

 

Yes I am getting the variable to the second script - The else clause is doing the output of the three lines, showing me it is in the else clause, the value of the $rtn variable and the type.  The value of $rtn is showing the backslashes and I am thinking that is why it won't equal to the comparison value of "A". 

[wildteen88]

Where in script1 are you setting the $rtn variable

[Pikachu2000]

I'd say it looks as though magic_quotes_gpc = On in your php.ini file, which it really shouldn't. If you can disable it, you should consider doing so as long as your other code is properly written to escape data when needed for db queries. If you can't disable it, you can run incoming form data through a function to get rid of unneeded slashes.

[westonm]

Ok sorry - let me try to get this right - here is code

 

Script 1

 <form action="dataProcess.php" method="POST" id="Email">
...
<input name="Rtn" type="hidden" value="<?php echo $rtn; ?>" />

 

Script 2

...
$rtn = ($_POST[Rtn]);

...
if ($rtn == "A") {
              header ("Location: http://www.***.com/foundation/MeetBoard.php");
              exit(0); 
} else {
                 echo "Fall to else ";
                 echo $rtn ;
                 echo gettype($rtn);
}

 

The output is coming from the else clause in the if stmt. 

it reads

Fall to else\A\string

So it is getting the value of "A" but has the backslashes that I think are preventing it from compaing . 

 

 

[Pikachu2000]

If you View ---> Source the output of script 1, is there an extra set of quotes in the value attribute in here?

<input name="Rtn" type="hidden" value="<?php echo $rtn; ?>" />

[fugix]

Your rtn index needs to be in single quotes

To Pikachu2000 -

That could be the problem - All of the other pages in the site were developed with Dreamweaver and has a function to take care of it.  I haven't understood exactly what it did but I guess I need to get into that to understand what it is not doing.  I had thought the stripslasched function would do the same thing, but maybe not.  I am on a shared newtork and do not have access to change php.ini settings, so will have to live with how it is set up now. 

[Pikachu2000]

OK. If you can't change the php.ini file, you should be checking for get_magic_quotes_gpc() and if it returns TRUE, use stripslashes() on the data (and mysql_real_escape_string() if it's going into a DB query string).

[westonm]

Using the magic_quotes functions didn't help.  I think I will take another approach and use session variables - maybe I will have better luck getting them to work.  I guess we can mark this as solved.
