Phalcon：异常：参数数量错误

Question

I want to execute a prepared insert:

<?php
function add_record($tab) {

        $champs= "";
        $value = "";
        $separateur ="";
        $ins = array();

        foreach ($tab as $k => $v){
            $champs .= $separateur . $k;
            $value .= $separateur . "?" ;
            $ins[] = $v;
            $separateur = ",";
        }
        $champs = '('.$champs.')';
        $value = '('.$value.')';

        $sSQL = "INSERT INTO facture $champs VALUES $value";

        executePreparedDML($sSQL, $ins);

    }

    function executePreparedDML($sSQL, $tab) {
    $config = array(
        "host" => SERVEUR,
        "dbname" => BDD,
        "port" => BDD_PORT,
        "username" => LOGIN_DB,
        "password" => PWS_DB);
    $connection = new \Phalcon\Db\Adapter\Pdo\Mysql($config);
    $statement = $connection->prepare($sSQL);
    $pdoResult = $connection->executePrepared($statement, $tab);
}
?>

When executing the add_record function then I got this error: Exception: Wrong number of parameters? So what is wrong ?

Answer 1

According to manual :

public PDOStatement executePrepared (PDOStatement $statement, array $placeholders, array $dataTypes)

Executes a prepared statement binding. This function uses integer indexes starting from zero

In other part of manual we can see that Phalcon allows bindings of names eg. = :email or bindings indexed as of ?0, ?1 .

As you function is serving array of [0 => 'first', 1 => 'second'] , i would test to create chain like (?0, ?1, ?2, ?3, ?4) instead of (?,?,?,?,?) .

You can also try to not prepare it the way you are doing it in question example and go straight for version from your own answer.

Also, when using models it is as easy as:

$obj = new credentialModel();
$isOk = $obj->save(array(
    'name' => 'John',
    'surname' => 'Doe'
));

and once you are using Phalcon, I would recommend to actually use it.

I wrote the sql manually but not dynamically :

$tab["fact_date"] = convertDateFormat5($tab["fact_date"]);

        $config = array(
        "host" => SERVEUR,
        "dbname" => BDD,
        "port" => BDD_PORT,
        "username" => LOGIN_DB,
        "password" => PWS_DB);

        $connection = new \Phalcon\Db\Adapter\Pdo\Mysql($config);

        $sSQL = "insert into facture(user_code,clt_id,fact_ref,fact_lib,fact_date,fact_comm) values(?,?,?,?,?,?)";

        $statement = $connection->execute($sSQL, array($tab['user_code'], $tab['clt_id'], $tab['fact_ref'], $tab["fact_lib"], $tab['fact_date'], $tab["fact_comm"]));
        $id = $connection->lastInsertId();
        $connection->close();

        return $id;

With this approach it works , so I dont understand why it doesnt when written dynamically !

just go to app/config/router.php and replace this line of code $router->handle() with $ router->handle($_SERVER['REQUEST_URI'])

Answer 4

It's a bit round about way of doing things, but considering all else in code is good, ie the $tab values, etc. the error is see is...

$sSQL = "INSERT INTO facture $champs VALUES $value"; should be $sSQL = "INSERT INTO facture " .$champs. " VALUES ". $value; $sSQL = "INSERT INTO facture " .$champs. " VALUES ". $value;
