it just seems like it would be more efficient to validate the form before even $_POSTing it... that way if a user doesn't have the correct information there isn't even any need for a redirect?
-
sorry, let me be more clear. here is my code: <!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" lang="en" xml:lang="en"> <head> <title>Login</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post"> screen name: <input type="text" name="login" maxlength="25"><br> password: <input type="password" name="pword" maxlength="25"><br> <input type="submit" name="submitbtn" value = "Login!"> </form> or Signup <a href="SignUp.php">here</a> <br> <?php //validation code would be here... if(username && password are correct) { //would be code to send user to game.php } } ?> </body> </html> i'd prefer to do the validation with a script on login.php, as i understand it is more efficient. So maybe i am in need of a way to do this with out generating any output... maybe the term i am looking for is not 'redirect'. I simply need to send the user to a new page after the password and user name are varified
-
ok, then how would i go about sending a user to, lets say, randomPage.php after i have validated their info on login.php...
-
I'm validating the info on the login.php page so i don't know if header() will work... does this require that i don't output any HTML data, or just don't use any PHP outputs? how does meta refresh work?
-
what is the syntax to redirect a user to a specific page? i have a script set up for user verification and i want it to redirect to a specific page when the user name and password are correct... can't seem to find the syntax for it in the php manual
-
How exactly would i set my input value's to the $_POST variables? is there any way you could show me an example of what you mean?
-
cool. any other must see tutorials?
-
learning PHP/mySQL (if you couldn't tell by all of my posts... ) i just found this tutorial, i was wondering how useful you all found it... http://www.php-mysql-tutorial.com/
-
ok, so i have developed a script for validating user input? I want to make it so that if a user does not enter the data correctly he/she does not have to fill it all out again. How would i do this? I'm just not quite sure where to find a tutorial on this
-
solved... syntax error i hate myself... hahah how come i can't modify my old posts to say this issue was solved?
-
well, i checked out phpMyAdmin and the it appears that the table isn't even being created... here is that code that is right before the previously posted query code. $input = "CREATE TABLE fans ( realName VARCHAR( 25 ) NOT NULL , uID bigint(20) NOT NULL AUTO_INCREMENT, screenName VARCHAR( 25 ) NOT NULL , password VARCHAR( 25 ) NOT NULL , PRIMARY KEY (`uID`), )"; mysql_query($input,$link); this code does not appear to be working...
-
very true treedude... i wasn't quite sure how to format the question i wanted answered. I had a conversation with my uncle and he basically suggested the same thing as you. to have a user table, and a table with the game/info about the game as well as a table that interacts between the two. I just couldn't wrap my brain around how awesome MySQL was hahaha. thanks, you guys rock
-
sorry, new to this php/mySQL stuff... here is the query $uInput = sprintf("INSERT INTO fans (realName,screenName,password) VALUES( '%s', '%s','%s')", mysql_real_escape_string($realName), mysql_real_escape_string($screenName), mysql_real_escape_string($password)); // run the query if(!mysql_query($uInput)) { echo 'Query failed '.mysql_error(); exit(); } else { echo "welcome to Pro Moto Fan bench racing!!!"; } } i believe this is what you're looking for?
-
the error that is spat out is... "Query failed Table 'moto.fans' doesn't exist"
-
i'm completely stumped... granted i'm not all that experienced with php/mySQL but i can't figure out what exactly is wrong with my code here. i'm sure there is a bunch though. the object of this program is to take user input/varify it. then if it is valid store it into a database (moto) under the table fans... the table doesn't seem to be created correctly (obviously an issue with my code) so here it is... sorry if its sloppy... <!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" lang="en" xml:lang="en"> <head> <title>Sign Up!</title> </head> <body> <p> <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post"> <label for="name">Name: </label> <input id="name" type="text" name="realName" maxlength="25" /><br /> <label for="name">Screen Name: </label> <input id="name" type="text" name="screenName" maxlength="25" /><br /> <label for="name">Password: </label> <input id="name" type="password" name="password" maxlength="25" /><br /> <label for="name">Confirm Password: </label> <input id="name" type="password" name="cPassword" maxlength="25" /><br /> <input id="submit" type="submit" value="Sign UP!" /><br /> </p> <?php function sanityCheck($string, $type, $length){ // assign the type $type = 'is_'.$type; if(!$type($string)) { return FALSE; } // to check if there is anything in the string elseif(empty($string)) { return FALSE; } // to check how long the string is elseif(strlen($string) > $length) { return FALSE; } else { // if all is well, we return TRUE return TRUE; } } function checkSet(){ return isset($_POST['realName'], $_POST['screenName'], $_POST['password'], $_POST['cPassword']); } if(checkSet() != FALSE) { if(empty($_POST['realName'])==FALSE && sanityCheck($_POST['realName'], 'string', 25)!=FALSE && empty($_POST['screenName'])==FALSE && sanityCheck($_POST['screenName'], 'string', 25)!=FALSE && empty($_POST['password'])==FALSE && sanityCheck($_POST['password'], 'string', 25)!=FALSE) { //If all is well the value of the POST is assigned to a variable... $realName = $_POST['realName']; $screenName = $_POST['screenName']; $password = $_POST['password']; $cPassword = $_POST['cPassword']; if($password !=$cPassword) { echo 'your passwords don not match'; exit(); } $link = @mysql_connect('localhost', 'root', 'zOinks12'); if (!$link) { die('Not connected : ' . mysql_error()); } $db_selected = mysql_select_db('moto', $link); if (!$db_selected) { die ("Database not selected : " . mysql_error()); } $input = "CREATE TABLE fans ( realName VARCHAR( 25 ) NOT NULL , screenName VARCHAR( 100 ) NOT NULL , password VARCHAR( 25 ) NOT NULL , )"; mysql_query($input,$link); // Query $uInput = sprintf("INSERT INTO fans (realName,screenName,password) VALUES( '%s', '%s','%s')", mysql_real_escape_string($realName), mysql_real_escape_string($screenName), mysql_real_escape_string($password)); // run the query if(!mysql_query($uInput)) { echo 'Query failed '.mysql_error(); exit(); } else { echo "welcome to Pro Moto Fan bench racing!!!"; } } else { echo 'You did not fill out all of the fields!!'; exit(); } } else { echo "Please fill out all of the above!"; } ?> </body> </html>

so you can store array's in a database? i haven't had much time to play around with MySQL much, but its finals week so i can probably figure the best we to structure the database i need then. thanks
-
I'm a bit new to MySQL and PHP... so i think this should be a simple question/answer. I'm creating a MySQL database that needs to support MANY different users and save all of their information (for a game). I have a decent amount of experience using C++, i'm just now venturing into the php realm. I can conceptualize an array to fit the data i need quite easily, i'm just not sure how MySQL handles what would be a 'multi-dimmensional array' in C++ I'm wondering if i should create an individual table for every user or just use one table to store all users and all of their information. i picture the data base i need as follows *Username*(main table) Sub sections: Password realName game choices [needs to store 10 different choices] raceNumber Does MySQL support multi-dimmensional arrays (which i think i would need for game choices) or is there a good to tie information together. -thanks for reading my programming dilemma's
-
makes sense... cool thanks
-
makes total sense, i feel silly for asking

Hi, i'm new to the world of coding for the web. I have a good amount of C++ experience... but i'm having trouble conceptualizing how the best way to handle variables from one page to another. For example, if i am creating a game and i want to validate the input. Is there a way to handle the html form on that same page that they input it? ok so basically can i take this basic form handling script.... Form: <form action="welcome.php" method="post"> Name: <input type="text" name="name" /> Age: <input type="text" name="age" /> <input type="submit" /> </form> welcome.php: <html> <body> Welcome <?php echo $_POST["name"]; ?>.<br /> You are <?php echo $_POST["age"]; ?> years old. </body> </html> and make it do something like this... welcome.php: <html> <body> <form action="randomFunction()" method="post"> Name: <input type="text" name="name" /> Age: <input type="text" name="age" /> <input type="submit" /> </form> <?php function randomFunction() { //validate input } ?> </body> </html> I'm really asking this for efficiency sake... I'm wondering if the best approach is to create a temporary MySQL table then validate using a separate php script, proceed to store the data permanently... so if that doesn't make any sense, what is the best method to receive user input/validate and store using MySQL...

thaank you =) this has really been getting on my nerves...

[pre]Hi, i'm new to php, needless to say i'm having trouble with the admin function of MySQL for Apache friend's XAMP it gives me an odd error whenever i have the admin window open through the control pannel. "access violation at adress 10002593 in module "LIBMYSQL.DLL" read of address 00000000" I have no clue what could be going on so any insight would be great[/pre]
