我有這個模式如下,我已經生成了使用symfony 的類,並使用生成的表單類創建了一對對象。條件:「未定義的偏移」

moto: 
    marca: { type: varchar(255), required: true } 
    matricula: { type: integer, required: true } 

現在我有這樣的條件:

$c = new Criteria(); 
    $c->addSelectColumn('MAX('.MotoPeer::MATRICULA.')'); 
    $max_matricula = MotoPeer::doSelect($c); 
    var_dump($max_matricula); 
    return $max_matricula; 

當我打電話的標準代碼,它工作正常,但是這三個通知如下 被顯示。

有什麼想法?

編輯:第一通知出現,因爲我沒有寫在模型的字段之前的「id:〜」。這裏有雲導致第二和第三通知書行:

/** 
    * Hydrates (populates) the object variables with values from the database resultset. 
    * 
    * An offset (0-based "start column") is specified so that objects can be hydrated 
    * with a subset of the columns in the resultset rows. This is needed, for example, 
    * for results of JOIN queries where the resultset row includes columns from two or 
    * more tables. 
    * 
    * @param  array $row The row returned by PDOStatement->fetch(PDO::FETCH_NUM) 
    * @param  int $startcol 0-based offset column which indicates which restultset column to start with. 
    * @param  boolean $rehydrate Whether this object is being re-hydrated from the database. 
    * @return  int next starting column 
    * @throws  PropelException - Any caught Exception will be rewrapped as a PropelException. 
    */ 
    public function hydrate($row, $startcol = 0, $rehydrate = false) 
    { 
     try { 

var_dump($row); 

    $this->id = ($row[$startcol + 0] !== null) ? (int) $row[$startcol + 0] : null; 
    $this->marca = ($row[$startcol + 1] !== null) ? (string) $row[$startcol + 1] : null;//184 
    $this->matricula = ($row[$startcol + 2] !== null) ? (int) $row[$startcol + 2] : null;//185 

我認爲,第二個和第三個聲明是因爲在我剛一列(maatricula)的標準顯示。但如何做到這一點?

如果使用「AddSelectColumn」的方法:

$c->addSelectColumn('MAX('.MotoPeer::MATRICULA.')'); 

你不能滋潤對象 - 你沒有選擇的所有列。因此,不叫:

MotoPeer::doSelect($c); 

而是做到這一點:

$c->addSelectColumn('MAX('.MotoPeer::MATRICULA.')'); 
$stmt = MotoPeer::doSelectStmt($c); 
$max_matricula = $stmt->fetchColumn(0); 

在這裏,您執行SQL語句並獲取你有興趣到變量$ max_matricula單值。
