... Récupération des valeurs des formulaires

Besoin: on veut récupérer le valeur d'un champs texte, on commence par un exemple basique et après on fait un exemple plus compliqué!

On doit créer deux page, la premire peut etre HTML ou bien php et la deuxieme obligatoirement php parce qu'elle va contenir le traitement du code php.

page1.html

Code HTML:

 <html> <body> <form method="post" action="page2.php"> 
Nom : <input type="text" name="prenom" size="12"><br> <input type="submit" value="OK"> </form> </body> </html>

page2.php

Code PHP:

  <?php 

$prenom = $_REQUEST["prenom"]; 

echo "Bonjour <b>$prenom </b>"; 
?>

Alors maintenant on sait comment récupérer les valeurs des forumulaires, on essaye de faire une petite calculatrice alors

:

Calculatrice1.php

Code HTML:

 <html> <body> <form method="post" action="page2.php">
Entier1 : <input type="text" name="n1" size="12"><br>
Entier2 : <input type="text" name="n2" size="12"> <br> <label> <select name="n3"> <option selected>+</option> <option>-</option> <option>*</option> <option>/</option> </select> </label> <br> <input type="submit" value="calculer"> </form> </body> </html>

Calculatrice2.php

Code PHP:

  <?php

$entier1 = $_REQUEST["n1"];
$entier2 = $_REQUEST["n2"];
$operateur = $_REQUEST["n3"];

if ($operateur=="+") {
$resultat=$entier1+$entier2;
}
else if ($operateur=="-") {
$resultat=$entier1-$entier2;
}
else if ($operateur=="/") {
$resultat=$entier1/$entier2;
}
else  {
$resultat=$entier1*$entier2;
}

echo "Le résultat de $entier1 $operateur $entier2 est $resultat";

//calculatrice pour les chers Asslemistes :D
?>

Voilà pour Aujord'hui

, on avance dans les prochaines jours, on attaquera la base de données (MySQL), les opérateurs logiques...

I'm a lazy student of you PHP coourse, but I had a question and I didn't found where to put it...
is it possible to design a persistent form? my vision is to put something like a game of "des mots croisé" ou "Sudoku" in a forum like this, so that all the users participate and fill it up until the end, that means, that if a user fill a bracket, then it stays filled and the next player could continue playing without modifying what the previous players filled.
may be it already exists, I can imagine some kind of forms that save the actuall inputs and use it in the next session.

salam,

Yes it's possible

, Php code is executed on server, so you can save the place of words for exemples..
I don't don't know if this is already existe, but what's sure is that it's possible, with a database...
You can start and I will help you if you have somes difficulties

nothing is impossible, something like this exist as a game but it don't make use of persistens on the web, but here we are able to do it, a GUI that accepts entries and stores them in a database, use them in the next session and at the end compare them to the right values.
sounds good but the implementation isn't so
