web课设 thinkphp5+mySQL 简易教学管理系统
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
教學管理系統 需求 結果展示 數據庫設計 實現 一、文件創建 二、前端界面 三、數據庫設置 四、控制器 五、前端返回信息處理
需求
有登錄界面，不同的用戶登錄后進入不同的頁面。 能完成基本數據（包括學生、教師、課程、選課）的增刪改。 根據指定要求完成查詢。 可以查詢指定姓名的學生或教師。 可以查找某位教師的授課門數。 可以查找指定學生選修的課程列表，包括課程名、任課教師、成績等。 可以查找指定所有課程的平均成績。
結果展示
登錄界面
學生界面
教師界面
管理員界面
數據庫設計

實現
一、文件創建
在thinkPHP5下的application內創建以下三個文件夾。
在controller文件夾內部新建一個php文件，作為控制器，命名為Signin.php。
二、前端界面
以登錄界面為例。
<!DOCTYPE html>
< htmllang = " en" > < head> < metacharset = " UTF-8" > < metaname = " viewport" content = " width=device-width, initial-scale=1.0" > < title> Document
</ title> </ head> < style> * { margin : 0; overflow : hidden; padding : 0; } li ul { list-style : none; } input { margin : 3px; outline : none; } input[type=text] { width : 300px; padding : 8px 20px; margin : 4px 0px 4px 0px; display : flex; border : 1px solid #ccc; border-radius : 4px; box-sizing : border-box; background : #F0F0F0; } input[type=text]:focus { width : 300px; padding : 8px 20px; margin : 4px 0px 4px 0px; display : flex; border : 1px solid #ccc; border-radius : 4px; box-sizing : border-box; background : white; } input[type=submit] { width : 300px; background-color : #A6100E; color : white; padding : 10px 20px; margin : 18px 0; border : none; border-radius : 4px; cursor : pointer; } input[type=submit]:active { width : 300px; background-color : #8D0E0C; color : #BEBEBE; padding : 10px 20px; margin : 18px 0; border : none; border-radius : 4px; outline : none; cursor : pointer; } input [type=submit]:after { outline : none; } select { width : 300px; padding : 8px 20px; margin : 4px 0px 4px 0px; border : 1px solid #ccc; border-radius : 4px; box-sizing : border-box; outline : none; } select:active { outline : none; } option { outline : none; } #header { display : flex; background : black; color : whitesmoke; flex-direction : row; } #header ul { display : flex; margin-left : 10%; } #header li { align-items : center; display : flex; font-weight : bold; font-size : 16px; } #header ul li:hover { background-color : #444444; cursor : pointer; } #header ul li:active { background-color : #656565; } #header a { display : inline-block; padding : 0 25px 0 25px; height : 60px; line-height : 60px; font-size : 16px; } #signIn { margin-top : 10%; margin-right : 10%; float : right; color : white; display : flex; flex-direction : column; } #hh { display : flex; } a { direction : none; } a:focus { cursor : pointer; }
</ style> < bodybackground = " ../../../../../TP/public/curricula/signin/img/02.jfif" > < divid = " header" > < ul> < li> < aherf = " signin" > 首頁
</ a> </ li> </ ul> </ div> < div> < formid = " signIn" method = " post" action = " {:url(' curricula/Signin/checkIdentity' )}" > < p> 用戶名
</ p> < inputtype = " text" name = " username" id = " username" placeholder = " username" /> < p> 密碼
</ p> < inputtype = " text" name = " password" id = " password" placeholder = " password" /> < p> 身份
</ p> < selectname = " identity" id = " identity" > < optionvalue = " s" > 學生
</ option> < optionvalue = " t" > 教師
</ option> < optionvalue = " a" > 尊敬的管理員
</ option> </ select> < inputtype = " submit" name = " btn1" value = " 登錄 login" /> </ form> </ div> </ body> 三、數據庫設置
數據庫建表過程略。數據庫名稱為student。
在application文件夾內有一個database.php文件，修改其中的信息，以連接mysql。
'type' = > 'mysql' , 'hostname' = > '127.0.0.1' , 'database' = > 'student' , 'username' = > 'root' , 'password' = > '168168' ,
在完成以上設置后，可以直接在表對應的model內，使用方法對完成增刪改查（以student為例）
use think\ Model ;
$M = $this ;
$sql = "要執行的SQL語句" ;
$r = $M - > execute ( $sql ) ;
$r 即為查詢的結果。
student.php
<?php namespace app\ curricula\ model ;
use think\ Model ; class Student extends Model
{ public function selStudentById ( $id ) $student = Student
: : get ( $id ) ; if ( $student ) { return true ; } else return false ; } public function addStudent ( $id , $name , $birth , $sex ) { if ( ! $this - > selStudentById ( $id ) ) { $M = $this ; $r = $M - > execute ( "insert into student values('" . ( string
) $id . "','" . ( string
) $name . "','" . ( string
) $birth . "','" . ( string
) $sex . "')" ) ; if ( $r ) return $this - > selAll ( ) ; else return false ; } else return false ; } public function delStudent ( $id ) / / $id , $name , $sex , $brith ) { if ( $this - > selStudentById ( $id ) ) { $M = $this ; $sql = "delete from student where s_id='" . ( string
) $id . "'" ; $r = $M - > execute ( $sql ) ; if ( $r ) { return $this - > selAll ( ) ; } else return false ; } else return false ; } public function uptStudent ( $id , $name , $birth , $sex ) / / $id , $name , $sex , $brith ) { $flag = false ; $M = $this ; if ( $this - > selStudentById ( $id ) ) { if ( $name && $name != '' ) { $sql = "update student set s_name='" . ( string
) $name . "'where s_id='" . ( string
) $id . "'" ; $r = $M - > execute ( $sql ) ; $flag = true ; } if ( $sex && $sex != '' ) { $sql = "update student set s_sex='" . ( string
) $sex . "'where s_id='" . ( string
) $id . "'" ; $r = $M - > execute ( $sql ) ; $flag = true ; } if ( $birth && $birth != '' ) { $sql = "update student set s_birth='" . ( string
) $birth . "'where s_id='" . ( string
) $id . "'" ; $r = $M - > execute ( $sql ) ; $flag = true ; } if ( $flag ) return $this - > selAll ( ) ; else return 2 ; } else return 1 ; } public function selStudentByName ( $name ) / / $id , $name , $sex , $brith ) { $M = $this ; $r = $M - > query ( "select * from student where s_name='" . $name . "'" ) ; if ( $r ) return $r ; else return false ; } public function selAll ( ) { $M = $this ; $r = $M - > query ( "select * from student" ) ; if ( $r ) { return $r ; } else return false ; }
}
四、控制器
注意點：
命名空間 namespace app\項目名\控制器文件夾名 必須引入幾個模型的位置， 返回時使用json()包裝數據 調用界面時使用view()函數 <?php namespace app\ curricula\ Controller ; use think\ Controller ;
use think\ Model ;
use app\ curricula\ model\ Student ;
use app\ curricula\ model\ Teacher ;
use app\ curricula\ model\ Users ;
use app\ curricula\ model\ Course ;
use app\ curricula\ model\ Score ;
use think\ migration\ command\ migrate\ Status ; define ( 'APP_DEBUG' , true ) ; class Signin extends Controller
{ public function signin ( ) { return view ( "signin" ) ; } public function student ( ) { return view ( "student" ) ; } public function teacher ( ) { return view ( "teacher" ) ; } public function admin ( ) { return view ( "admin" ) ; } public function addScore ( $id , $id2 , $s ) { return ( new \ app\ curricula\ model\ Score( ) ) - > addScore ( $id , $id2 , $s ) ; } public function checkIdentity ( ) { $username = $_POST [ 'username' ] ; $password = $_POST [ 'password' ] ; $identity = $_POST [ 'identity' ] ; $r = ( new \ app\ curricula\ model\ Users( ) ) - > check ( $username , $password , $identity ) ; $data = array ( "status" = > false , "info" = > array ( ) ) ; if ( ! $r ) { $this - > redirect ( 'signin' ) ; } if ( $identity == 's' ) $this - > redirect ( 'student' ) ; else if ( $identity == 't' ) $this - > redirect ( 'teacher' ) ; else if ( $identity == 'a' ) $this - > redirect ( 'admin' ) ; else $this - > redirect ( 'signin' ) ; } public function selScoreCT ( ) { $id = $_GET [ 'id' ] ; $r = ( new \ app\ curricula\ model\ Score( ) ) - > selScoreCT ( $id ) ; $data = array ( "status" = > false , "info" = > array ( ) ) ; if ( $data == false ) { return ( json ( $data ) ) ; } else { $data [ "status" ] = true ; $data [ "info" ] = $r ; return ( json ( $data ) ) ; } } public function deladdScore ( ) { $ch = $_GET [ "ch" ] ; $sid = $_GET [ "sid" ] ; $cid = $_GET [ "cid" ] ; if ( $ch == 'del' ) { $r = ( new \ app\ curricula\ model\ Score( ) ) - > stuDelScore ( $sid , $cid ) ; $data = array ( "status" = > false , "info" = > array ( "ERROR" ) ) ; if ( $r == - 1 ) { $data [ "status" ] = - 1 ; $data [ "info" ] = "成績已登陸，別想改啦" ; return ( json ( $data ) ) ; } if ( $r == false ) { return ( json ( $data ) ) ; } else { $data [ "status" ] = true ; $data [ "info" ] = $r ; return ( json ( $data ) ) ; } } else if ( $ch == 'add' ) { $r = ( new \ app\ curricula\ model\ Score( ) ) - > stuAddScore ( $sid , $cid ) ; $data = array ( "status" = > false , "info" = > - 1 ) ; if ( $r == - 2 ) { $data [ "status" ] = - 2 ; $data [ "info" ] = "你已選擇這門課程" ; return ( json ( $data ) ) ; } if ( $r == - 1 ) { $data [ "status" ] = - 1 ; $data [ "info" ] = "沒有這門課程" ; return ( json ( $data ) ) ; } if ( $r == - 3 ) { $data [ "status" ] = - 3 ; $data [ "info" ] = "插入失敗" ; return ( json ( $data ) ) ; } else { $data [ "status" ] = true ; $data [ "info" ] = $r ; return ( json ( $data ) ) ; } } } public function selCourseMS ( ) { $tid = $_GET [ 'tid' ] ; $r = ( new \ app\ curricula\ model\ Course( ) ) - > countCourse ( $tid ) ; $data = array ( "status" = > false , "info" = > array ( ) , "cnum" = > '0' ) ; if ( ! $r || $r [ 0 ] [ 'c_num' ] == 0 ) return json ( $data ) ; else { $data [ "cnum" ] = ( string
) $r [ 0 ] [ 'c_num' ] ; $r = ( new \ app\ curricula\ model\ Course( ) ) - > selCourse ( $tid ) ; $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function selTeacherId ( ) { $tname = $_GET [ 'name' ] ; $r = ( new \ app\ curricula\ model\ Teacher( ) ) - > selTeacherId ( $tname ) ; $data = array ( "status" = > false , "info" = > "查無此人" ) ; if ( ! $r ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function selCourseAVG ( ) { $c = $_GET [ 'cid' ] ; $cid = '' ; for ( $i = 0 ; $i < count ( $c ) ; $i ++ ) { $cid . = "'" . $c [ $i ] . "'" ; if ( $i != count ( $c ) - 1 ) { $cid . = ',' ; } } $r = ( new \ app\ curricula\ model\ Course( ) ) - > selCourseAVG ( $cid ) ; $data = array ( "status" = > false , "info" = > "無課程信息" ) ; if ( ! $r ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function uptScore ( ) { $sid = $_GET [ 'sid' ] ; $cid = $_GET [ 'cid' ] ; $sc = $_GET [ 'sc' ] ; $r = ( new \ app\ curricula\ model\ Score( ) ) - > uptScore ( $sid , $cid , $sc ) ; $data = array ( "status" = > false , "info" = > "無課程信息" ) ; if ( ! $r ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function addStudent ( $sid , $sname , $sbth , $sex ) { $r = ( new \ app\ curricula\ model\ Student( ) ) - > addStudent ( $sid , $sname , $sbth , $sex ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == false ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function delStudent ( $sid ) { $r = ( new \ app\ curricula\ model\ Student( ) ) - > delStudent ( $sid ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == false ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function uptStudent ( $id , $name , $sbth , $sex ) { $r = ( new \ app\ curricula\ model\ Student( ) ) - > uptStudent ( $id , $name , $sbth , $sex ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == 1 || $r == 2 ) { $data [ "status" ] = $r ; return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function addTeacher ( $id , $name ) { $r = ( new \ app\ curricula\ model\ Teacher( ) ) - > addTeacher ( $id , $name ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == false ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function delTeacher ( $id ) { $r = ( new \ app\ curricula\ model\ Teacher( ) ) - > delTeacher ( $id ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == false ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function uptTeacher ( $id , $name ) { $r = ( new \ app\ curricula\ model\ Teacher( ) ) - > uptTeacher ( $id , $name ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == 1 || $r == 2 ) { $data [ "status" ] = $r ; return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function addCourse ( $cid , $name , $tid ) { $r = ( new \ app\ curricula\ model\ Course( ) ) - > addCourse ( $cid , $name , $tid ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == false ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function delCourse ( $id ) { $r = ( new \ app\ curricula\ model\ Course( ) ) - > delCourse ( $id ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == false ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function uptCourse ( $cid , $name , $tid ) { $r = ( new \ app\ curricula\ model\ Course( ) ) - > uptCourse ( $cid , $name , $tid ) ; $data = array ( "status" = > false , "info" = > "失敗" ) ; if ( $r == 1 || $r == 2 ) { $data [ "status" ] = $r ; return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } } public function studentADU ( ) { $ch = $_GET [ 'ch' ] ; $sid = $_GET [ 'sid' ] ; $sname = $_GET [ 'sname' ] ; $sbth = $_GET [ 'sbth' ] ; $sex = $_GET [ 'sex' ] ; if ( $ch == 'add' ) { return $this - > addStudent ( $sid , $sname , $sbth , $sex ) ; } else if ( $ch == 'del' ) { return $this - > delStudent ( $sid ) ; } else if ( $ch == 'upt' ) { return $this - > uptStudent ( $sid , $sname , $sbth , $sex ) ; } else return $data = array ( "status" = > false , "info" = > "失敗" ) ; } public function teacherADU ( ) { $ch = $_GET [ 'ch' ] ; $id = $_GET [ 'tid' ] ; $name = $_GET [ 'tname' ] ; if ( $ch == 'add' ) { return $this - > addTeacher ( $id , $name ) ; } else if ( $ch == 'del' ) { return $this - > delTeacher ( $id ) ; } else if ( $ch == 'upt' ) { return $this - > uptTeacher ( $id , $name ) ; } else return $data = array ( "status" = > false , "info" = > "失敗" ) ; } public function courseADU ( ) { $ch = $_GET [ 'ch' ] ; $cid = $_GET [ 'cid' ] ; $name = $_GET [ 'cname' ] ; $tid = $_GET [ 'tid' ] ; if ( $ch == 'add' ) { return $this - > addCourse ( $cid , $name , $tid ) ; } else if ( $ch == 'del' ) { return $this - > delCourse ( $cid ) ; } else if ( $ch == 'upt' ) { return $this - > uptCourse ( $cid , $name , $tid ) ; } else return $data = array ( "status" = > false , "info" = > "失敗" ) ; } public function selAllCourseAVG ( ) { $r = ( new \ app\ curricula\ model\ Course( ) ) - > selAllCourseAVG ( ) ; $data = array ( "status" = > false , "info" = > "無課程信息" ) ; if ( !

$r ) { return json ( $data ) ; } else { $data [ "info" ] = $r ; $data [ "status" ] = true ; return json ( $data ) ; } }
}
五、前端返回信息處理
前端使用ajax提交并顯示數據
ajax簡單入門
//需引入jquery
< scriptsrc = " http://libs.baidu.com/jquery/2.1.4/jquery.min.js" > </ script> function func ( ) { $
. ajax ( { url
: "delXXX" , type
: 'GET' , data
: { 'sid' : $ ( "#sid" ) . val ( ) , 'cid' : $ ( "#cid" ) . val ( ) } , success
: function ( data
) { } } ) ; }
以學生按姓名查詢信息為例：
function inquiryStuByName ( ) { if ( $ ( "#sname" ) . val ( ) == '' ) { alert ( "Empty Input!" ) ; return ; } $
. ajax ( { url
: "selStudentByName" , type
: 'GET' , data
: { "sname" : $ ( "#sname" ) . val ( ) } , success
: function ( data
) { if ( ! data
. status
) alert ( "ERROR" ) ; else { var str
= style
; str
+= "<Table class='pure-table pure-table-bordered'>" ; str
+= "<tr> <td>學號</td> <td>姓名</td><td>出生日期</td><td>性別</td></tr>" ; for ( var i
= 0 ; i
< data
. info
. length
; i
++ ) { str
+= '<tr>' ; str
+= ( "<td>" + data
. info
[ i
] . s_id
+ "</td>" ) ; str
+= ( "<td>" + data
. info
[ i
] . s_name
+ "</td>" ) ; str
+= ( "<td>" + data
. info
[ i
] . s_birth
+ "</td>" ) ; str
+= ( "<td>" + data
. info
[ i
] . s_sex
+ "</td>" ) ; str
+= '</tr>' ; } str
+= "</Table>" $ ( "#show" ) . html ( str
) ; } } } ) ; }
