Question

我在Magento的PHP中有以下代码，它试图将特定文件中的连接值插入到一个表中

    $extencion = '.jpg';
    $test ='/small/';
    $_prodId= 1;

   $conn  = Mage::getSingleton('core/resource')->getConnection('core_write');

$sql = "update catalog_product_entity_varchar
        set value = ".$test.$_prodId.$extencion."
        where entity_id = ".$_prodId."
        and attribute_id  = 86 ";

$result = $conn->query($sql);

我试过在更新之前连接值

$concatenate = $test.$_prodId.$extencion;

但没有成功，任何想法如何解决这个问题？

Answer 1

您必须将字符串插入引号：

$sql = "update catalog_product_entity_varchar
    set value = '".$test.$_prodId.$extencion."'
    where entity_id = ".$_prodId."
    and attribute_id  = 86 ";

Answer 2

    $extencion = '.jpg';
    $test ='/small/';
    $_prodId= 1;

    $resource = Mage::getSingleton('core/resource');
    $adapter = $resource->getConnection('write');

    $bind = array(
        'value' => $test.$_prodId.$extencion
    );

    $where = array(
        'entity_id = ?'     => $_prodId,
        'attribute_id = ?'  => 86
    );

    $adapter->update($resource->getTableName('catalog_product_entity_varchar'), $bind, $where);
