Pergunta

I have this piece of code:

if (isset($_POST['username']) && isset($_POST['email'])) {

$query = $pdo->prepare('INSERT INTO users (name, email, joined) VALUES (?, ?, ?)') or die ('Error.');
$query->bindValue(1, $_POST['username']);
$query->bindValue(2, $_POST['email']);
$query->bindValue(3, time());

$query->execute();

$sql = mysql_query('SELECT * FROM users;');

while ($row = mysql_fetch_array($sql)) {

    echo ('<div style="font-weight: bold;">' .$row['name']. '</div>');
    echo ($row['email']);
    echo ('<br>');
    echo ('Posted: ');
    echo date('F j, Y, g:i a', strtotime($row['joined']));

}

}

which it accuses this error:

mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\WebServer\htdocs\newsSite\register.php on line 21

and on another file (below), it works fine, but i don't see the difference between them: 

<body>
<?php

$query = mysql_query('SELECT * FROM posts;');

while ($row = mysql_fetch_array($query)) {

    echo ('<div style="font-weight: bold;">' .$row['title']. '</div>');
    echo ($row['post']);
    echo ('<br>');
    echo ('Posted: ');
    echo date('F j, Y, g:i a', strtotime($row['date']));

}

?>
</body>
Foi útil?

Solução

Try like this, this my code snippet I have used long before,

    // PDO
$pdo = new PDO('mysql:dbname=test;host=127.0.0.1', 'example', 'example');

print '<h3>PDO: simple select</h3>';
foreach($pdo->query( 'SELECT * FROM users;' ) as $row)
{
    //Fetching data
}

Outras dicas

The problem is (probably) that your query returns false (hence "boolean"), due to some error in the query string or logic. Try "SELECT 1" instead of your query string and if it works well, you'll know for sure that the difference (the cause) must be in the query.

put one function after this line ,

$sql = mysql_query('SELECT * FROM users;');
echo mysql_error();

you have a error into query .
