session variable Q

[dadamssg]

i want to keep what a user inputs in my form in a session variable so i can transfer it over to a page where he can then check what he inputs before submitting to my database. how do i store the POST variables into a session variable to use in the next page?

this isn't working

 

$_SESSION['$_POST['$title']]= $title;

 

the name for the input field is 'title'

Don't you mean

$_SESSION['title'] = $_POST['title'];

? The other thing doesn't make sense...

[RussellReal]

$_SESSION['$_POST['$title']]= $title;

 

ok.. idk you obviously don't see whats wrong with this picture, however I'll risk losing first post in order to FULLY explain it to you lol

 

ofcourse you'd use the superglobal $_SESSION

 

but

 

you started a single quote which would denote a literal text value would follow, then terminated by another single quote..

 

E.G.

 

$_SESSION['literalTextValue']

 

however you are doing 2 things wrong here

 

literal strings do not evaluate variables for starters

 

secondly you forgot a terminating quote (')

 

My advice for you here, is to always when you're expecting to write a string, automatically write two quotes, instead of just 1 before, and 1 after.. this way you can never make this mistake again.

 

for the variable, you need to know that that will never work

 

and would probably not be the best option for you!

 

plain and simple

 

$_SESSION['title'] = $_POST['title'];

 

would do just fine..

 

please don't just copy/paste the aboev.. try and know exactly why your script wasn't working, and never make the mistake again..

 

Happy Coding

i think thats it but why am i getting another error when im trying to call that variable later? any ideas?

 

<?php

/* File: checkpost.php*/

include("caneck.inc");

session_start();

$_SESSION['title'] = $_POST['title'];
$_SESSION['description'] = $_POST['description'];
$_SESSION['event'] = $_POST['event'];



echo "<table border='7'>
       <tr>
       <td><b>Title:&nbsp</b></td><td>$_SESSION['title']</td>
       </tr>                        
       <tr>
       <td><b>Description:&nbsp</b></td><td>$_SESSION['description']</td>
       </tr>
       <tr>
       <td><b>Event Type:&nbsp</b></td><td>$_SESSION['event']</td>
       </tr>
       <tr>
       <td colspan=2><center><form action='submitpost.php' method='POST'><input type='submit' name='post' value='post'>
       </center></form>
       </td>                       
       </tr>
       </table>";
  
?>
