上载php上载页面上的类别
你好，我正在做一个有上传页面的项目，它在后台以dir/uploads/上传图片，并将其保存到用户_images表中我数据库中的url 所以，我想有一个分类画廊，但当他们上传时，我需要一个下拉菜单，让他们选择汽车、房子等 在我的图库中，我需要显示类别。我在想所有有id的类别 当我提交时，表格将是id和image_链接，在gallery页面中，我在这个div中指定我想要id=x的图像 有人能帮我吗？我会非常高兴的！ps：对不起，我的英语不好 编辑：我需要它与pdo再次感谢 upload.php上载php上载页面上的类别,php,mysql,pdo,Php,Mysql,Pdo,你好，我正在做一个有上传页面的项目，它在后台以dir/uploads/上传图片，并将其保存到用户_images表中我数据库中的url 所以，我想有一个分类画廊，但当他们上传时，我需要一个下拉菜单，让他们选择汽车、房子等 在我的图库中，我需要显示类别。我在想所有有id的类别 当我提交时，表格将是id和image_链接，在gallery页面中，我在这个div中指定我想要id=x的图像 有人能帮我吗？我会非常高兴的！ps：对不起，我的英语不好 编辑：我需要它与pdo再次感谢 upload.php

什么东西没有按预期工作？你需要什么帮助？我会在“user\u image”表中为类别id添加一个类似“category\u id”的列，并将所选类别保存在其中。然后，您可以按类别加载所有图像，从用户图像中选择图像链接，其中类别id=123，其中123是要显示的类别的id。这就是你要找的吗？
