php - let a forum in a div reload without the page reloading -
i curious know if it's possible can have div reload window does. reason have forum don't want full page reload after 4 completed. wondering if elements in div or forum section background reload or load them self when submit button pressed.
this in file called forum information gets typed in. want not reload page stay on forum , still send data database.
<html> <body> <form action="demo.php" method="post" /> <p>input 1: <input type="text" name="firstname" /></p> <input type="submit" value="submit" /> </form> <div id = "load_results"></div> </body> </html>this sending information database want done discreetly.
<?php $servername = "localhost"; $username = "root"; $password = "root"; $dbname = "mydb"; // create connection $conn = new mysqli($servername, $username, $password, $dbname); // check connection if ($conn->connect_error) { die("connection failed: " . $conn->connect_error); } $value = $_post['firstname']; $sql = "insert myguests (firstname) values ('$value')"; if ($conn->query($sql) === true) { echo "<a href=https://twitter.com/angela_bradley>my twitter</a>"; } else { echo "error: " . $sql . "<br>" . $conn->error; } $conn->close(); ?>
yes, there way. called ajax - but, not worry, it's pretty simple.
your code this:
html:
<form action="demo.php" method="post" /> <p>input 1: <input type="text" name="firstname" /></p> <input type="submit" value="submit" /> </form> js/jquery:
$(function(){ $('form').submit(function(evt){ //next line stops form submission sending `demo.php` evt.preventdefault(); //evt stands "event" - can anything. use e.preventdefault() var fn = $('[name=firstname]').val(); $.ajax({ type: 'post', url: 'demo.php', //send data demo.php -- page stays data: 'first='+fn, success: function(d){ if (d.length) alert(d); } }); //end ajax }); //end document.ready demo.php
<?php $fn = $_post['fn']; //do database insert here //if wish, can return data ajax's success function: echo 'you submitted: ' .$fn; here posts simple ajax examples:
