Question

noob问题在这里，我正在尝试检索编辑类别标签下面的输入表单中的类别标题，这是我能够做的（http://localhost:8080/cms/admin/categories.php?edit=10&title=Node%20JS）＆lt; - 输出后我点击编辑ahref（假设我点击身份证号码10），但当我尝试更改值并尝试使用提交时出现问题 submit_edit按钮网址就像这样http://localhost:8080/cms/admin/categories.php?cat_title=Test&submit_edit=Edit+Category+ 我无法使用_GET检索id，所以我可以编辑它。

将此内容放入您的编辑表单

<input type="hidden" name="edit" value="<?=$at_id?>">

使用GET提交表单时，url会有所不同
