Namtip Posted August 31, 2010 Share Posted August 31, 2010 This is a multi page registration form. I want to check the user input from form1.php with preg_match in form2.php then return the users details back into form1 with error messages(e.g $errname) so the user doesn't need to re enter the information. Neither the error messages or the session variables are shown in form1.php's form. I've echoed out the session variables found that the value makes it to form 2. But the variables are empty when it goes back to form 1. form1.php <html> <head> <title>Register</title> <style type="text/css"> td { vertical-align: top; } .errText { font-family: Arial; font-size: 10px; color: #CC0000; text-decoration: none; font-weight: normal; } </style> </head> <body> <form action="form2.php" method="post"> <table> <tr> <td><label for="name">Username:</label></td> <td><input type="text" name="name" id="name" size="20" maxlength="20" value="<?php echo $_SESSION['name'];?>"/> <?php if(isset($_POST[$errname])) echo $errname;

I think I should buy a professional book, instead of my beginner one. Quote Link to comment Share on other sites More sharing options...
AbraCadaver Posted August 31, 2010 Share Posted August 31, 2010 You need a session_start() in form1 or else when you redirect back to it there is no session. Quote Link to comment Share on other sites More sharing options...
Namtip Posted September 1, 2010 Author Share Posted September 1, 2010 Ah! good spot! I could kiss you! That's go the sessions to pass through to form1 but my error messages still aren't coming up . Any clues? Quote Link to comment Share on other sites More sharing options...
AbraCadaver Posted September 1, 2010 Share Posted September 1, 2010 Ah! good spot! I could kiss you! That's go the sessions to pass through to form1 but my error messages still aren't coming up . Any clues? Well, I don't know all of your code, but form2 is not making any sense. I haven't tested, but this is more like what it should be I think: //let's start the session session_start(); //let's store our posted values in the session variables $_SESSION['values'] = $_POST; //let's check for errors $error = array(); if( preg_match('/^[A-Z][a-zA-Z -]{3,30}+$/',$_POST['name']) ) { $error['name'] = '<p class="errText">Name must be from letters, dashes, spaces and must not start with dash</p>'; } if( preg_match('/^[A-Z][a-zA-Z -]{3,30}+$/',$_POST['first_name']) ) { $error['first'] = '<p class="errText">Name must be from letters, dashes, spaces and must not start with dash</p>'; } if( preg_match('/^[A-Z][a-zA-Z -]{3,30}+$/',$_POST['last_name']) ) { $error['last'] = '<p class="errText">Name must be from letters, dashes, spaces and must not start with dash</p>'; } if( preg_match('/^[a-zA-Z]\w+(\.\w+)*\@\w+(\.[0-9a-zA-Z]+)*\.[a-zA-Z]{2,4}$/',$_POST['email']) ) { $error['email'] = '<p class="errText">This is not a valid email address.'; } if( preg_match('/^[a-zA-Z0-9 _.,:\"\']+$/',$_POST['address']) ) { $error['address'] = '<p class="errText">Address must be only letters, numbers or one of the following ". , : /"</p>'; } if( preg_match('/[a-zA-Z]+/',$_POST['city']) ) { $error['city'] = '<p class="errText">Your city must contain a letter.'; } if( preg_match('/[a-zA-Z]+/',$_POST['county']) ) { $error['county'] = '<p class="errText">Your county must contain a letter.'; } if( preg_match('/(GIR 0AA)|((([A-Z-[QVX]][0-9][0-9]?)|(([A-Z-[QVX]][A-Z-[iJZ]][0-9][0-9]?)|(([A-Z-[QVX]][0-9][A-HJKSTUW])|([A-Z-[QVX]][A-Z-[iJZ]][0-9][ABEHMNPRVWXY])))) [0-9][A-Z-[CIKMOV]]{2})/',$_POST['post']) ) { $error['post'] = '<p class="errText">This is not a valid UK Postcode.'; } if( preg_match('/s*\(?0\d{4}\)?(\s*|-)\d{3}(\s*|-)(\d{3}\s*)|(\s*\(?0\d{3}\)?(\s*|-)\d{3}(\s*|-)\d{4}\s*)|(\s*)(7|(\d{7}|\d{3}(\-|\s{1})\d{4})\s*/',$_POST['home']) ) { $error['home'] = '<p class="errText">This is not a valid UK local phone number.'; } if( preg_match('/^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/',$_POST['mobile']) ) { $error['mob'] = '<p class="errText">This is not a valid UK mobile phone number.'; } //if we have errors let's assign them to the session and redirect back, you could just assign to $_SESSION['error']['name'] etc.. above if(!empty($error)) { $_SESSION['error'] = $error; header("Location: form1.php"); exit; } So in form1 they would each need to look something like this: <td><label for="name">Username:</label></td> <td><input type="text" name="name" id="name" size="20" maxlength="20" value="<?php echo isset($_SESSION['values']['name']) ? $_SESSION['values']['name'] : ""; ?>"/> <?php echo isset($_SESSION['error']['name']) ? $_SESSION['error']['name'] : ""; ?></td> Quote Link to comment Share on other sites More sharing options...
Namtip Posted September 1, 2010 Author Share Posted September 1, 2010 Hmmm, Yup, that works, except its giving me error messages for the correctly entered parts of the form. I should be able to sort that out though. Hopefully. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
