I'm able to retrieve the corresponding data from the database with this code.But im having n number of images,it is not possible to create that many number of pages and i dont think it is optimal.How can i do this for multiple images???
You can put an onclick like
<img src="getimage.php?itemId=oepsv1007" alt="image" id="img1" onclick="get_detail('oepsv1007');">
then do a ajax call to get the detail using this id.
javascript function
function get_detail(id) {
// ajax call
}

Im trying to echo the information that is inserted to my database. As im pretty new to coding php im not really sure how i could manage to do this. My database name is "nyheter" and the table is "post". So i want to selecte the data from db and echo it on the page.
<?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$link = mysqli_connect("localhost", "root", "", "nyheter");
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
//get results from database
$result = mysqli_query($connection,"SELECT * FROM post");
$all_property = array(); //declare an array for saving property
?>

You're selecting everything from the database. So you've to use a loop to display the content you've selected from the database.
Write something similar to this:
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
echo "name: " . $row["name"]."<br>";
}
} else {
echo "0 results";
}
mysqli_close($conn); ?>
Hope this was helpful.
Here's what I'm trying to do. I'm trying to echo blog posts stored in my database. Simple enough, but I want them to be redirected to view_post.php to show the full post, when they click on the little preview. Here's my code:
<?php
session_start();
require_once('required/db.php');
$_SESSION['admin'] = false;
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

<link rel="ico" href="assets/favicon.ico">
</head>
<body>
<nav><h2 class="title">The Blog</h2></nav>
<?php
$sql="SELECT id,title,author,body FROM posts ORDER BY id DESC";
if ($result=mysqli_query($con,$sql))
{
// Fetch one and one row
while ($row=mysqli_fetch_row($result))
{
printf('<div class="row"><div class="row-inner"><p><strong>%s</strong> | %s |</p></div></div>', $row[0],$row[1],$row[2]);
}
// Free result set
mysqli_free_result($result);
}
mysqli_close($con);
?>
<div class="top-margin wrapper"><div class="container"><p>Administrator? Click here.</p></div></div>
</body>
</html>
How would I go about making the preview row a link dynamically (such as view_post.php?id=1)? What would I put in view_post.php?
Assumming on $row the id is contained you can create the links like this
printf('<a href="view_post.php?id='.$row['id'].'"> <----just put the id there
And on view_port use the value
<div class="row"><div class="row-inner">
<p><strong>%s</strong> | %s |</p></div></div></a>', $row[0],$row[1],$row[2]);
I want to make a page where the element will redirect the user to a random page from the database.
I made the HTML code, but I can not deal with PHP and MySQL - I was able to connect to the database, but any attempt to connect the MySQL code with the tag ended in a loss.
Can I count on help writing a PHP script and linking code with ?

Let's try this:
Put this PHP part at the top of the page;
<?php
// set a default link in case something goes wrong
$DEFAULT_LINK = "default.html";
// connect to DB
require_once "connect.php";
$conn = new mysqli($host, $db_user, $db_password, $db_name);
// set query -> get 1 result only with LIMIT 1
$sql = "SELECT link FROM randomit ORDER BY RAND() LIMIT 1";
$result = mysqli_query($conn, $sql);
if ($result !== false)
$row = mysqli_fetch_assoc($result);
else
$row = false;
// if we have a valid result => use it
// else => use the default
if ($row && isset($row["link"]))
$RANDOM_LINK = $row["link"];
else
$RANDOM_LINK = $DEFAULT_LINK;
?>
And now the HTML part:
<!DOCTYPE html>
<html>
<!-- head part... -->
<body>
<header></header>
<div class="random">

<footer></footer>
<!-- etc... -->
I am looking for a way where when a user uploads a image in PHP it shows them the URL to the file.
My current upload.php is the following:
<?php
if(!empty($_FILES)){
//database configuration
$dbHost = 'localhost';
$dbUsername = 'root';
$dbPassword = '';
$dbName = 'codexworld';
//connect with the database
$conn = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);
if($mysqli->connect_errno){
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
$targetDir = "http://wotm8.net/";
$fileName = $_FILES['file']['name'];
$targetFile = $targetDir.$fileName;
if(move_uploaded_file($_FILES['file']['tmp_name'],$targetFile)){
//insert file information into db table
$conn->query("INSERT INTO files (file_name, uploaded) VALUES('".$fileName."','".date("Y-m-d H:i:s")."')");
}
}
?>
Ignore the database. I don't use that
if you need the index file or anything else then ask.

I think your upload directory is $targetFile
You can echo it out or return it in any way you think is safe
Like after insert into database
echo $targetFile;
EDIT
Your target dir should be a absolute path, not a website link, should be something like /var/www/folder/
I doubt your upload is working in the example you posted.
after you manage to make the upload successful, just echo your domain + relative folder ( if any) + filename.
I'm trying to develop a login system in PHP which has faculty_login.php which displays faculty_login_option.inc.php which has a login form and if $_SESSION['f_id'] is set it redirects to faculty_upload_option.php. where faculty details are fetched from faculty_table using $f_id = $_SESSION['f_id'] as the primary key.but $_SESSION['f_id'] is always returning 1 and user is logging in as the user whose f_id is 1.
<?php
//faculty login page.faculty_login.php
//if logged in show upload option/show login option.
require_once 'resources/core.inc.php';//session is set here
require_once 'resources/connect.inc.php';//init db connection
if(isset($_SESSION['f_id'])&&!empty($_SESSION['f_id'])){
require_once 'faculty_upload_option.inc.php';
}
else{
require_once 'faculty_login_option.inc.php';
}
?>
<?php
/* faculty_login_db.php
* Check if the faculty can login or the credentials are wrong.
*/
require_once 'resources/core.inc.php';
require_once 'resources/connect.inc.php';
if(isset($_POST['f_username'])&&isset($_POST['f_password'])){

Are you destroying session correctly on logout? Are you setting session id before hitting the condition somewhere? What is the value before hitting the comparion condition?
