Sanjib Sinha Posted February 4, 2009 Share Posted February 4, 2009 I have two pages new_user.php and another in my includes file form_functions.php code of new_user.php is as follows: <?php require_once("includes/connection.php"); ?> <?php require_once("includes/functions.php"); ?> <?php include_once("includes/form_functions.php"); // START FORM PROCESSING if (isset($_POST['submit'])) { // form has been submitted. $errors = array(); // perform validation on the form data $required_fields = array('username', 'password'); $errors = array_merge($errors, check_required_fields($required_fields, $_POST)); $fields_with_lengths = array('username' => 30, 'password' => 30); $errors = array_merge($errors, check_max_field_lengths($fields_with_lengths, $_POST)); $username = trim(mysql_prep($_POST['username'])); $password = trim(mysql_prep($_POST['password'])); $hashed_password = sha1($password); if(empty($errors)) { $query = "INSERT INTO users ( username, hashed_password ) VALUES ( '{$username}', '{$hashed_password}' )"; $result = mysql_query($query); if (mysql_affected_rows() == 1) { // Success $message = "The user was successfully created. "; } else { $message = "The user could not be created. "; $message .= "<br />" . mysql_error(); } } else { if (count($errors) == 1){ $message = "There was one error in the form."; } else { $message = "There were " . count($errors) . " errors in the form."; } } // END FORM PROCESSING } else { // form has not been submitted $username = ""; $password = ""; } ?> <?php include("includes/header.php"); ?> <table id="structure"> <tr> <td id="navigation"> <a href="staff.php">Return to Menu</a><br /> <br /> </td> <td id="page"> <h2>Create New User</h2> <?php if (!empty($message)) { echo "<p class=\"message\">" . $message . "</p>";} ?> <?php if (!empty($errors)) { display_errors($errors); } ?> <form action="new_user.php" method="post"> <table> <tr> <td>Username</td> <td><input type="text" name="username" maxlength="30" value="<?php echo htmlentities($username); ?>" /></td> </tr> <tr> <td>Pasword</td> <td><input type="password" name="pasword" maxlength="30" value="<?php echo htmlentities($password); ?>" /></td> </tr> <tr> <td colspan="2"><input type="submit" name="submit" value="Create user" /></td> </tr> </table> </form> </td> </tr> </table> And the form_functions.php code is like this: <?php function check_required_fields($required_array){ $field_errors = array(); foreach($required_array as $fieldname){ if (!isset($_POST[$fieldname]) || (empty($_POST[$fieldname]) && $_POST[$fieldname] != 0)){ $field_errors[] = $fieldname; } } return $field_errors; } function check_max_field_lengths($field_length_array){ $field_errors = array(); foreach($field_length_array as $fieldname => $maxlength){ if (strlen(trim(mysql_prep($_POST[$fieldname]))) > $maxlength){ $field_errors[] = $fieldname; } } return $field_errors; } function display_errors($error_array){ echo "<p class=\"errors\">"; echo "Please review the following fields:<br />"; foreach($error_array as $error) { echo " - " . $error . "<br />"; } echo "</p>"; } ?> Now the output comes as Notice: Undefined index: password in C:\wamp\www\Bengali_Friends\includes\form_functions.php on line 15 Notice: Undefined index: password in C:\wamp\www\Bengali_Friends\new_user.php on line 19 Why this happens? Any idea from anyone? Quote Link to comment Share on other sites More sharing options...
uniflare Posted February 4, 2009 Share Posted February 4, 2009 An index is a "Label" for an array item. eg; $test = Array( "this_is_an_index" => "this is a value", 1 => "another value, 1 is the index" ); so, echo($test['this_is_an_index']); would echo ("this is a value"); echo($test[1]); // would echo ("another value, 1 is the index");, as you can see $test['password'] would give you an "Undefined Index", or "Array item does not exist". i believe $_POST['password'] doesnt exist, try using: (anywhere, it will show you the form data available to that page). echo("<PRE>"); var_dump($_POST); echo("</PRE>"); Quote Link to comment Share on other sites More sharing options...
peranha Posted February 4, 2009 Share Posted February 4, 2009 <input type="password" name="pasword" maxlength="30" value="<?php echo htmlentities($password); ?>" /></td> should be <input type="password" name="password" maxlength="30" value="<?php echo htmlentities($password); ?>" /></td> your name only has 1 s in password, not 2 Quote Link to comment Share on other sites More sharing options...
