Question

这是我的代码

我可以将数据添加到表中

我无法创建删除和修改按钮

我英语不好，但我会尽力了解你的情况。

<?php 
     $cat_id = $conn->real_escape_string($_REQUEST['Cat_id']);
     $Cat_name = $conn->real_escape_string($_REQUEST['Cat_name']);
     if(isset($_REQUEST['save'])){
     $sql = "insert into category_(Cat_id,Cat_name)
             value('".$_REQUEST["Cat_id"]."','".$_REQUEST["Cat_name"]."')";
     $insert_cat = $conn->query($sql);  
}
if($_REQUEST['del']){
$sql1 = "delete from category_ where cat_id ='".$_REQUEST["Cat_id"]."' and cat_name='".$_REQUEST["Cat_name"]."' ";
$delete = $conn->query($sql1);
}   
?>

表

我无法从mycode中删除数据

我想添加一个删除选项，该选项调用另一个表单。我似乎无法使其正常工作。

请帮助我
