推荐答案Joomla 组件对于您的需求的确切场景将很难找到.所以你有两个选择:1. 制作自己的组件2. 自定义图库组件等其他类似类型的组件
Joomla Component for the exact scenario of your requirement will be very hard to find out. So you've two options: 1. Make your own component 2. Customize other similar type of component like gallery component
如果您正在制作自己的组件,则用于从管理员上的 joomla 组件上传文件:1. 只需使用move_uploaded_file php 函数.2. 复制此代码,用于 joomla 的标准 fxn :
For uploading file from joomla component on admin if you're making your own component: 1. Just use move_uploaded_file php function. 2. copy this code, for joomla's standard fxn :
function upload($src, $dest) { jimport('joomla.client.helper'); $FTPOptions = JClientHelper::getCredentials('ftp'); $ret = false; $dest = JPath::clean($dest); $baseDir = dirname($dest); if (!file_exists($baseDir)) { jimport('joomla.filesystem.folder'); JFolder::create($baseDir); } if ($FTPOptions['enabled'] == 1) { jimport('joomla.client.ftp'); $ftp = & JFTP::getInstance($FTPOptions['host'], $FTPOptions['port'], null, $FTPOptions['user'], $FTPOptions['pass']); $dest = JPath::clean(str_replace(JPATH_ROOT, $FTPOptions['root'], $dest), '/'); if (is_uploaded_file($src) && $ftp->store($src, $dest)) { $ret = true; unlink($src); } else { JError::raiseWarning(21, JText::_('WARNFS_ERR02')); } } else { if (is_writeable($baseDir) && move_uploaded_file($src, $dest)) { // Short circuit to prevent file permission errors if (JPath::setPermissions($dest)) { $ret = true; } else { JError::raiseWarning(21, JText::_('WARNFS_ERR01')); } } else { JError::raiseWarning(21, JText::_('WARNFS_ERR02')); } } return $ret; }如果你想使用别人的组件并根据需要编辑它,下载它:prakashgobhaju.np/index.php?option=com_showcase_gallery&view=items&catid=1&Itemid=64记住它是一个画廊组件.
If you want to use other's component and edit it according to need, download it: prakashgobhaju.np/index.php?option=com_showcase_gallery&view=items&catid=1&Itemid=64 Remember it's a gallery component.
