表格如下:
virtuemart_customfield_id___|___virtuemart_product_id___|____custom_value___
1 | 4346 | 45
2 | 4346 | 46
3 | 4347 | 45
此功能正常工作。
function getSizes($product_id){
global $mainframe;
$db = &JFactory::getDBO();
$sql = 'SELECT * FROM `#__virtuemart_product_customfields` WHERE `virtuemart_product_id` ='.$product_id.'';
$db->setQuery($sql);
$result=$db->loadObjectList();
return $result;
}
这是调用函数并从数据库中获取数据的代码,并尝试用逗号分隔我需要的值。
$records = $this->getSizes($product_id);
$product_size = '';
foreach ($records as $value){
$size = $value->custom_value;
if ($product_size == '') {
$product_size .= $size;
} else {
$product_size .= ", " .$size;
}
问题似乎出现在这段代码中,但我不知道在哪里...... 任何帮助将非常感激! 提前谢谢!

尝试这种方式(firts分配给$ size而不连接)
$records = $this->getSizes($product_id);
$product_size = '';
foreach ($records as $value){
$size = $value->custom_value;
if ($product_size == '') {
$product_size = $size;
} else {
$product_size .= ", " .$size;
}
}
