Implementation of PHP Student management system

Recently the school opened a PHP course, by the way to write a homework, share it ...

It's a simple thing to do 、、、

Omit part of the front-end code 、、、

The first is the check for login:

<?PHPSession_Start(); $user=$_post[' UserName ']; $pass=$_post[' PassWord ']; $_session[' user '] =$user; /*$Enter = $_post[' Login_undo '); Check for administrator login*/    $flag=false; if($user= = "Admin" &&$pass= = "Root")    {        Setcookie("UserName",$user, Time() +1200); Setcookie("UserName",$pass, Time() +1200); $flag=true; Header(' location:adminpage.php?user= '.$user); }    Else        Header(' Location:login.php?login=relog '); /*//Student Login-free if ($Enter) header (' location:StuPage.php '); */            

Then is the registered checksum:

<?PHPSession_Start(); $s _id=$_post[' s_id ']; $Name=$_post[' Name ']; $IDcard=$_post[' Idcard ']; $Major=$_post[' Major ']; $sex=$_post[' Sex ']; $_session[' Student '] [$s _id[' s_id '] =$s _id; $_session[' Student '] [$s _id[' Name '] =$Name; $_session[' Student '] [$s _id[' idcard '] =$IDcard; $_session[' Student '] [$s _id[' Major '] =$Major; $_session[' Student '] [$s _id[' sex '] =$sex; Header(' location:tisi.html '); /*foreach ($_session[' student ') as $v) {if ($v = = $s _id) {header ("Location:stu_reg.php?actio n=look&msg= update &user=employee&empno= ". $empno. "&idcard=".        $idcard); } else Header ("location:stu_reg.php?action=look&msg= add &user=employee&empno=". $empno. "&idcard=".    $idcard); }*/

Graduation operation and accession history check:

<?PHPSession_Start(); $s _id=$_get[' s_id ']; $_session[' History '] [$s _id[' s_id ']=$s _id; $_session[' History '] [$s _id[' Name ']=$_session[' Student '] [$s _id[' Name ']; $_session[' History '] [$s _id[' Idcard ']=$_session[' Student '] [$s _id[' Idcard ']; $_session[' History '] [$s _id[' Sex ']=$_session[' Student '] [$s _id[' Sex ']; $_session[' History '] [$s _id[' Major ']=$_session[' Student '] [$s _id[' Major ']; unset($_session[' Student '] [$s _id]); Header(' Location:graduate.php?user=admin&action=delete ');

Any keyword query:

<?PHPSession_Start(); $search=$_post[' Search ']; unset($_session[' Search ']); /*echo ' <pre> ';    Var_dump ($_post[' search '); return;*/    foreach($_session[' Student '] as $k 1=$value) {        #code ...        if($search==$_session[' Student '] [$k 1[' s_id ']| |$search==$_session[' Student '] [$k 1[' Idcard ']| |$search==$_session[' Student '] [$k 1[' Name ']| |$search==$_session[' Student '] [$k 1[' Sex ']| |$search==$_session[' Student '] [$k 1[' Major ']){            $i= 1; $stu=$_session[' Student '] [$k 1[' s_id ']; $_session[' Search '] [$stu] =$stu; }    }    if(isset($i))        Header("Location:stu_query.php?user=admin&action=search"); Else         Header("Location:stu_query.php?user=admin&action=q_error");

Traverse Student Information:

<! DOCTYPE html>class= "Css_table" bgcolor= ' #E1E1E1 ' ><?PHPSession_Start(); $user=isset($_session[' User ']?$_session[' User ']: '; if($user= = ' Admin '){        if(isset($_session[' Student '])){            foreach($_session[' Student '] as $k 1) {             Echo"<tr>"; foreach($k 1  as $k 2=$k 3) {            Echo"<td>" ; if($k 2= = ' s_id ') {Echo"Study number:";}Else if($k 2= = ' Idcard ') {Echo"ID number:";}Else if($k 2= = ' sex ') {Echo"Sex:";}Else if($k 2= = ' Name ') {Echo"Name:";}Else if($k 2= = ' Major ') {Echo"Professional:";}; Echo"</td>"; Echo"<td>"; if($k 2= = ' s_id ')$s _id=$k 3;Echo"$k 3"; Echo"</td>"; }        }    }}?></table></body>
Update the page and verify the data:
