jhvn147 Posted July 13, 2012 Share Posted July 13, 2012 Hi everyone, I am new with php. I study it at Uni but have a problem. The code below is that of the 4 php files I created so far. The index takes you to the copper and steel pages, which can then take you to the cartaction page. This is a kind of shopping cart. My problem is that when I enter the values in the copper page, I can see them in the cartaction page - but if I now go to the steel page and enter values there, and then return to the cartaction page, the values from the copper page dissappeared. I have tried many combinations and I am sure you might help. Thank you. (jhvn147) Here is the code: index.php <?php session_start( ); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <link rel="stylesheet" href="styles/site.css" type="text/css" /> </head> <body> <div id="mainblock"> <table> <tr> <td> <a href="copperrange.php">C </a> </td> </tr> <tr> <td> <a href="steelrange.php">S </a> </td> </tr> </table> </div> <form method="post" action="cartaction.php"> <p> <input type="submit" name="submit" value="Show" /> <input type="hidden" name="cartaction" value="display" /> </p> </form> </body> </html> copperrange.php <?php session_start( ); if (isset($_SESSION['steelcasserole'])) { $_SESSION['steelcasserole'] = $_POST['steelcasserole']; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <title>Copper</title> <link rel="stylesheet" href="styles/site.css" type="text/css" /> </head> <body> <table> <tr><td><?php echo "CpC: " . $_SESSION["coppercasserole"];?></td></tr> <tr><td><?php echo "Csp: " . $_SESSION["coppersaucepan"]; ?></td></tr> <tr><td><?php echo "Cs : " . $_SESSION["coppersaute"]; ?></td></tr> <tr> <form action="cartaction.php" method="post"> <input type="text" name="coppercasserole" value="<?php echo $_SESSION['coppercasserole']; ?>"> <input type="submit" value="View"> <form action="cartaction.php" method="post"> <input type="text" name="coppersaucepan" value="<?php echo $_SESSION['coppersaucepan']; ?>"> <input type="submit" value="View"> <form action="cartaction.php" method="post"> <input type="text" name="coppersaute" value="<?php echo $_SESSION['coppersaute']; ?>"> <input type="submit" value="View"> </tr> </table> <div id="footer"> <form method="post" action="cartaction.php"> <input type="submit" name="submit" value="Show" /> <input type="hidden" name="cartaction" value="display" /> </form> </div> <ul class="navlist"> <li><a href="index.php">Home</a></li> </ul></body></html> steelrange.php <?php session_start( ); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <title>Steel</title> <link rel="stylesheet" href="styles/site.css" type="text/css" /> </head> <body> <table> <tr><td><?php echo "CpC: " . $_SESSION["steelcasserole"];?></td></tr> <tr><td><?php echo "Csp: " . $_SESSION["steelfrying"]; ?></td></tr> <tr> <form action="cartaction.php" method="post"> <input type="text" name="steelcasserole" value="<?php echo $_SESSION['steelcasserole']; ?>"> <input type="submit" value="View"> <form action="cartaction.php" method="post"> <input type="text" name="steelfrying" value="<?php echo $_SESSION['steelfrying']; ?>"> <input type="submit" value="View"> </tr> </table> <div id="footer"> <form method="post" action="cartaction.php"> <input type="submit" name="submit" value="Show" /> <input type="hidden" name="cartaction" value="display" /> </form> </div> <ul class="navlist"> <li><a href="index.php">Home</a></li> </ul></body></html> Quote Link to comment Share on other sites More sharing options...
