Symfony1 标准:“;“未定义的偏移量”;
下面是这个模式,我使用symfony生成了类 并使用生成的form类创建了一对对象Symfony1 标准:“;“未定义的偏移量”;,symfony1,criteria,propel,offset,Symfony1,Criteria,Propel,Offset,下面是这个模式,我使用symfony生成了类 并使用生成的form类创建了一对对象 moto: marca: { type: varchar(255), required: true } matricula: { type: integer, required: true } 现在我有了这个标准: $c = new Criteria(); $c->addSelectColumn('MAX('.MotoPeer::MATRICULA.')'); $max_matricu
moto:
marca: { type: varchar(255), required: true }
matricula: { type: integer, required: true }
现在我有了这个标准:
$c = new Criteria();
$c->addSelectColumn('MAX('.MotoPeer::MATRICULA.')');
$max_matricula = MotoPeer::doSelect($c);
var_dump($max_matricula);
return $max_matricula;
当我调用标准代码时,它工作正常,但这三个注意事项
下面是一些例子
有什么想法吗
sf 1.4/1.4
(!)注意:未定义的偏移量:2英寸

0.2578 5953424 BaseMoto->hydrate()../BaseMotoPeer.php:408 编辑:出现第一个通知,因为我没有在模型的字段前写上“id:~”。这里是导致第二个和第三个通知的行:
/**
* 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
我认为,第二个和第三个通知是显示的,因为在标准中,我只得到一列(maatricula)。但如何做到这一点呢
Javier如果使用“AddSelectColumn”方法:
您不能为对象添加水合物-您没有选择所有列。因此,不要呼吁:
MotoPeer::doSelect($c);
而是这样做:
$c->addSelectColumn('MAX('.MotoPeer::MATRICULA.')');
$stmt = MotoPeer::doSelectStmt($c);
$max_matricula = $stmt->fetchColumn(0);
这里执行SQL语句,并将感兴趣的单个值提取到变量$max\u matricula中。如果使用“AddSelectColumn”方法:
