This for loop displays only the last entry of the student record

This might help you You are using the same variable inside the for loop. on each iteration the last entered student get deleted and replaced with the new data. You should use an array (or any other suitable data structure for your use case) and add a new Student in the array on every iteration.
this code should work:
arr = list()
for i in range(n):
    emp=student()
    emp.read()
    arr.append(emp)

PHP,MYSQL while loop only displays the last record


Tag : php , By : Grik

will be helpful for those in need Each time you iterate, you overwrite $info variable. You have to add rows to $info array.
$dbhost = 'localhost';    
$dbuser = 'root';    
$dbpass = '';  
$dbname = 'moviefone';    
$con = mysql_connect($dbhost, $dbuser, $dbpass);  
mysql_select_db($dbname, $con);    

// Check connection    
if (mysqli_connect_errno()) {  
    echo "Failed to connect to MySQL: " . mysqli_connect_error();    
}    

$data = mysql_query("SELECT * FROM new_hindi") or die(mysql_error());
$info=array();
while ($row = mysql_fetch_array($data)){
    $info[]=$row;
}

Defining a delete(student st[], int *itemcount) function to delete a target record from the array of student objects

I wish this help you I'm trying to learn C programming so i was trying to do some practices. as you see below the search function only returns 1 or -1 and the variable index is being used to determine whether the target student exists or not. but after that it is again being used to determine whether it is the last, in the middle, or the first item in the array. how can index have that numeric value when we already assigned the returned value from the search function to it? please help me figure this out. thank you.

if (strcmp (st[i].stnumber, id) == 0)
    found = i;
. . .
return found;

Bookshelf.js - After updating record, initial page load/query displays old record. After refresh data displays correctly

wish helps you You are writing you saving data like synchronous code, so the save() may (and often will) happen AFTER the refresh(). Try changing that to:
    Table.where({id: req.param.id}).fetch()
    .catch(function (err) {
        console.log(err);
    })
    .then(function (results) {
        return results
          .set('other_column', null)
          .save();
    })
    .then(function (results) {  // results should now include the saved data
        // Redirect to orders page
        res.redirect('/landing-page');
    });

Any of those help I am working on MVC. I need to selecr list of students based on enrolled department wise and display them on different divs departmentalize, based on enrolled department in view. My database sample Schemas is as follow , You can do it like this (I implemented your issue !!):
DB Tables
public ActionResult NewStudentFeeStatus()
        {
            ViewBag.DeparmentList = db.tblDepartments.ToList();
            List<tblStdEnrollment> enrollmentList = (from p in db.tblStdDetails
                                                     join e in db.tblStdEnrollments on p.ID equals e.Stdref_id
                                                     select e).ToList();
            return View(enrollmentList);
        }
@model IEnumerable<tblStdEnrollment>    

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>NewStudentFeeStatus</title>
</head>
<body>
    <div>
        @foreach (var item in @ViewBag.DeparmentList)
        {            
            <div>@item.DepartName</div>
            foreach (var student in Model.Where(s => s.Depart_ref_id == item.ID).ToList())
            {                
                <div>@student.tblStdDetail.Name</div>
            }
        }
    </div>
</body>
</html>

PHP, mySQL, and Smarty template. while loop only displays 1 database entry


Tag : php , By : arbeitandy

wish of those help Just like what I've said in the comments, the reason why you're only getting the last row value is because every iteration inside your loop, the values gets overwritten.
A way that you can do is to create a container, then use your while loop and put them all inside first. After you're done, then ->assign() it inside the template and make your loop presentation and logic and other stuff that you need to do.
// Backend

$data = array(); // initialize a simple container
$query = "SELECT * from recipes";
$result = mysqli_query($db_server, $query);

if ($result->num_rows > 0) {
    // fetch rows
    while($row = $result->fetch_assoc()) {
        $data[] = $row; // push them inside
    }
}

// assign user information to template
$tpl->assign('values', $data);


// Front end

<div class="content">
    {foreach from=$values key=k item=value}
        <h4>{$value.title}<h4>
        <h6>{$value.submission_date}</h6>
        <p>{$value.instructions}</p>
        <p>{$value.category}</p>
    {/foreach}
</div>
