Question

i`m just starting in php, and I was wondering how to make a sign up form. I’m not really sure on how to add the values to the database. I’m using phpMyAdmin for the databases.

I have the inputs here:

<div id="registerSpace">
 <form id="formulaireInscription2" name="formSignup" method="post" action="signUp.php">
  <div class="registerUsername"><input type="text" placeholder="Username" name="txtUserName" /><span class="textInputs"></span></div>
  <div class="registerNom"><input type="text" placeholder="First name" name="txtNom" /><span class="textInputs">First name</span></div>
  <div class="registerPrenom"><input type="text" placeholder="Last name" name="txtPrenom" /><span class="textInputs">Family name</span></div>
  <div class="registerPassword"><input type="password" placeholder="Password" name="txtPassword" /><span class="textInputs">Password</span></div>
  <div class="dropLogonContentOptions"><input type="submit" value="Sign Up" name="send" />
 </form>
</div>

I put all my code in signUp.php.
In phpMyAdmin, my database’s called jleggett_colourful, and my table (where the user, password, first name blabla) is: t_usagers.
In there, I have u_id(auto increment, numbers only), u_nom(last name), u_prenom(first name), u_courriel(mail, also username!) and u_password.

What would be the best way to add it to the database? I have this code here:

<?php 
 session_start();

 include 'inc/define.inc.php';
 include 'inc/fct.inc.php';



 if (isset($_POST["txtUserName"]) && isset($_POST["txtNom"]) && isset($_POST["txtPrenom"]) && isset($_POST["txtPassword"]))
 {
  // Ouvre une connexion au serveur MySQL
  $connection = mysql_connect(NOM_SERVEUR, USER_NOM, USER_PASSWORD) or die("Impossible de se connecter : " . mysql_error());
  if (!$connection) {
    fin_perso('Problème de connexion au serveur : '. ' ---' . NOM_SERVEUR. '- - -' . USER_NOM. '- - -' . USER_PASSWORD. '- - - '  . mysql_error(), 'erreur_bd_');
  }

  // S�lectionne une base de données MySQL
  if (!mysql_select_db(NOM_BD))
  {
     fin_perso('Problème de connexion à la base de données : ' . mysql_error(), 'erreur_bd');
  }

  $sql = "INSERT INTO t_usager (u_nom, u_prenom, u_password) VALUES ('fdfs', 'qwerty', '456789')";

 else
  echo "Please, enter all informations"
?>

I’m a bit lost here, but it should look like this! The code to connect to the database is correct, I just don’t know how to add it with the values from my form. Thx! (I have entered default values, just for testing in $sql).

Answer 1

You will change the following:

$sql = "INSERT INTO t_usager (u_nom, u_prenom, u_password) VALUES ('fdfs', 'qwerty', '456789')";

to use the values in the $_POST array (i.e. $_POST[‘txtUsername’]). And then after you build the string for your query, you will need to call mysql_query ( $sql ); in order to actually run the query.

I believe that you are also missing a pair of {} within your code because the line with $sql on it is currently not valid (with the else right after since there is no nearby if it can relate to).

Code Example:

$nom = mysql_real_escape_string ( $_POST [ 'txtNom' ] );
$preNom = mysql_real_escape_string ( $_POST [ 'txtPrenom' ] );
$pass = mysql_real_escape_string ( $_POST [ 'txtPassword' ] );
$sql = "INSERT INTO t_usager (u_nom, u_prenom, u_password) VALUES ('$nom', '$preNom', '$pass')";
