Question

I try to create a query getting from a formular through post function. The post function must pass a text and an int variable to create the query sent to database.

When I start execute my php script, it says: undefined index, for the int variable.

I dont understand why the int variable isn’t recognized. here is my code:

formulaire04.php

<form action="selection_jeux.php" method="post">
    <p>
    Nom
    <input type="text" name="possesseur"/>
        Prix maximum
    <input type="int" name="prixmax"/>
    <input type="submit" value="Valider"/>
    </p>
</form>

selection_jeux.php

<?php
    try
    {
        $bdd = new PDO('mysql:host=localhost;dbname=test' , 'root', '');
    }
    catch(Exception $e)
    {
        die('Erreur : '.$e->getMessage());
    }
    $req = $bdd->prepare('SELECT nomselec, prix FROM jeux_video WHERE possesseur = :possesseur AND prix <= :prixmax');
    $req->execute(array('possesseur'=> $_POST['possesseur'], 'prixmax'=> $_POST['prixmax']));

    echo '<ul>';

    while($donnees = $req->fetch())
    {
        echo '<li>'  . $donnees['nom'] . ' (' . $donnees['prix'] . ' EUR)</li>'; 
    }
    echo '<li>';

    $req->closeCursor();
?>

Answer 1

The issue is in the SQL Statement not the HTML markup

On your prepare statement you have SELECT nomselec,prix
but on your while statement you have $donnees[‘nom’] not nomselec

Could that be the issue?

To all the people saying int isn’t a valid type, this does not matter it still gets posted as normal;

Example:

<?php
if(isset($_POST))
{
    print_r($_POST);
}
?>
<form action="" method="post">
<p>
Nom
<input type="text" name="possesseur"/>
Prix maximum
<input type="int" name="prixmax"/>
<input type="submit" value="Valider"/>
</p>
</form>

Returns:

Array ( [possesseur] => test [prixmax] => 123 )
