Question

我想在Knowledgedetail中插入de EmployeeID和KnowledgeID。他创建了员工，但在Knowledgedetail中没有做任何事情。我现在没有代码，我尝试了很多东西，但我不知道首先在Addprofile.php中创建配置文件，至少你选择了你的知识。我的问题是，如果制作个人资料并选择知识如何获得我在知识中的ID。

表1 员工：员工ID，姓名，编制，电子邮件，电话号码，照片，说明
表2 知识：KnowledgeID，Knowledge
表3 Knowledgedetail ：KnowledgedetailID，EmployeeID KnowledgeID

EmployeeID out员工与EmployeeID有关系，知识权限和知识 KnowledgeID out Knowledge与KnowledgeID outledegedetail

有关系

这是你的代码有一个问题：

$knowledge = mysql_query($sqldetail);                                       

if ($add === false){
    echo 'Knowledge is not added';
}
else {               
    echo "Knowledge added";
}

在if声明中，您应该比较$knowledge而不是$add。所以，它应该是：

$knowledge = mysql_query($sqldetail);                                       

if ($knowledge === false){
    echo 'Knowledge is not added';
}
else {               
    echo "Knowledge added";
}

此外，每次mysql_error()失败时都会向mysql_query()添加电话：

echo "MySQL ERROR: SQL = $sql -- Error=".mysql_error()";
