Hello fellow freaks.

Im still getting to grips with php so please go easy on me. No throwing rotton vegetables at me for silly mistakes, i beg you.

 

Im creating a registration form with php. The information added on the form is to be added into the psql database (in the users table - consisting of first name, last name, username, and password)

 

heres my code so far

 

NB: im behind the times and having to work with PHP 5, not 6 unfortunately

 

<html>
    <head><title> Register </title></head>
        <body>
        <?
                $self =         $server ['PHP_SELF'];
                $first_name =   $_post ['first_name'];
                $last_name =    $_post ['last_name'];
                $username =   $_post ['username'];
                $password =    $_post ['password'];
        
        if ( ( !$first_name ) or (!$last_name) or (!$username) or (!$password) )
            
        {
        
        $form.="Please enter your details below to register with Sporticket";
        $form.="<form action=\"$self\"";
        $form.=" method=\"post\"> First Name: ";
        $form.="<input type=\"text\" name=\"first_name\"";
        $form.=" value=\"$first_name\"><br>Last Name: ";
        $form.="<input type=\"text\" name=\"last_name\"";
        $form.=" value=\"$last_name\"><br>Username: ";
        $form.=" <input type=\"text\" name=\"username\"";
        $form.=" value=\"$username\"><br>Password: ";
        $form.=" input type=\"text\" name=\"password\"";
        $form.=" value=\"$password\"><br>";
        $form.=" <input type=\"submit\" value=\"Submit\">";
        $form.=">/form>";
        
        }
        
        else
        
        {
        
        $conn = @pg_connect(~connection details hidden~);
        
        $psql = "insert into users (first_name,last_name,username,password) values
        (\"$first_name\",\"$last_name\",\"$username\",
        password(\"$password\")  )";   
        
        $result = pg_query($conn)
        or die ("Could not execute query");
        if ( $result ) { echo ( "Congratulations, You can now log into Sporticket with the username and password you supplied" ) ; }
        
        }
        ?>
        
        </body
</html>

 

 

and im recieving these errors:

 

Notice: Undefined variable: server in /home2/webusers/07/344740/public_html/sporticket/register.php on line 5

 

Notice: Undefined variable: _post in /home2/webusers/07/344740/public_html/sporticket/register.php on line 6

 

Notice: Undefined variable: _post in /home2/webusers/07/344740/public_html/sporticket/register.php on line 7

 

Notice: Undefined variable: _post in /home2/webusers/07/344740/public_html/sporticket/register.php on line 8

 

Notice: Undefined variable: _post in /home2/webusers/07/344740/public_html/sporticket/register.php on line 9

 

Notice: Undefined variable: form in /home2/webusers/07/344740/public_html/sporticket/register.php on line 15

 

 

any help is appreciated  :D

should be:

                $self =         $_SERVER['PHP_SELF'];
                $first_name =   $_POST['first_name'];
                $last_name =    $_POST['last_name'];
                $username =   $_POST['username'];
                $password =    $_POST['password'];

Thanks alot rhodesa.

I kinda feel like im letting you do all the work for me.

Atleast i had the basic framework to begin with, as im guessing you sometimes have post that say "i want this, how do i do it" and wait for a prgrammer to come along and code the whole thing.

I am 16 and this is all new to me.

 

I've made a few more changes and the form appears with no errors.

 

when submitted i get this....

 

Warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error at or near "Resource" at character 1 in /home2/webusers/07/344740/public_html/sporticket/register2.php on line 17

Could not execute query

 

 

 

this is now my current code

 

<html>
    <head><title> Register </title></head>
        <body>
<?php
  if(isset($_POST['first_name'])){  
    $first_name =   pg_escape_string($_POST['first_name']);
    $last_name =    pg_escape_string($_POST['last_name']);
    $username =   pg_escape_string($_POST['username']);
    $password =    pg_escape_string($_POST['password']);

    if ( ( !$first_name ) or (!$last_name) or (!$username) or (!$password) ){
      die("Missing some values");
    }

    $conn = @pg_connect(===========================================);
    $psql = "INSERT INTO users (first_name,last_name,username,password) VALUES ('$first_name','$last_name','$username',password('$password'))";   
    $result = pg_query($conn) or die ("Could not execute query");
    if ( $result ) {
      echo "Congratulations, You can now log into Sporticket with the username and password you supplied";
    } else {
      echo "Failed to add user";
    }
  }else{
        
        $form ="Please enter your details below to register with Sporticket";
        $form.="<form action=\"\"";
        $form.=" method=\"post\"> First Name: ";
        $form.="<input type=\"text\" name=\"first_name\"";
        $form.=" <br>Last Name: ";
        $form.="<input type=\"text\" name=\"last_name\"";
        $form.=" <br>Username: ";
        $form.=" <input type=\"text\" name=\"username\"";
        $form.=" <br>Password: ";
        $form.=" <input type=\"text\" name=\"password\"";
        $form.=" <br>";
        $form.=" <input type=\"submit\" value=\"Submit\">";
        $form.="</form>";
     
     echo $form;
  }
?>
        </body>
</html>
