I am creating a website that contains different movies, every movie has a specific id_movie, i have added a comment box where the user can add a comment about the movie, however, every movie i click on, they all show the same comments that have been entered, I want every movie to have its own comments, I will be happy if you can help me with that. thanks

comments.php
//add the target files URL as the form's action

//add movie to the form, that way when we insert the comment we know what its for
<input type="hidden" name="movie_id" id="movie_id" value="<?php echo $movie_id; ?>" />
//.. in your JS, add the movie id to the fetch comment call
function load_comment()
{
$.ajax({
url:"fetch_comment.php",
method:"POST",
data: {movie_id : <?php echo $movie_id; ?>},
dataType: 'json',
success:function(data){
//...
})
}
//move this below the function definition
load_comment();
add_comment.php
//add movie id here to match what is in the form above
INSERT INTO tbl_comment
(parent_comment_id, comment, comment_sender_name, movie_id)
VALUES (:parent_comment_id, :comment, :comment_sender_name, :movie_id)
// add ':movie_id' => $_POST['movie_id'] to the array you have there for
// $statement->execute([ ....]). The arrays below go the same way
//add those to $statement->execute() for there respective DB calls,
You had the movie in the FIELDS part of the insert, but not the VALUES, which is probably an SQL syntax error. You may not have seen an actual error because this is called with AJAX so it would just break on the client side. You could look in the browser debug window > network [XHR] requests and look at the response. There you would probably find it or you may simply get a 500 error from the server.
fetch_comment.php
//add movie id here to match what is in the AJAX fetch comment call
SELECT * FROM tbl_comment
WHERE parent_comment_id = :parent_comment_id AND movie_id = :movie_id
ORDER BY comment_id DESC
//for execute add
['parent_comment_id'=>0, 'movie_id'=>$_POST['movie_id']]
Important prepare this query properly
$query = "
SELECT * FROM tbl_comment WHERE parent_comment_id = '".$parent_id."'
";
So it should be like this:
$query = "SELECT * FROM tbl_comment WHERE parent_comment_id = :parent_id";
//then add this to execute ['parent_id' => $parent_id]
mainpage.php (not sure the name on this one)
In the last unnamed code chunk you are using mysqli but above your using PDO it's better to use one or the other, personally I prefer PDO, its just better API wise. You are also not preparing these (so convert these to PDO). Using both just adds unnecessary complexity to your application (I think there were 2 of theses in there):
$qry2=mysqli_query($con,"select * from tbl_movie where movie_id='".$_GET['id']."'");
$movie=mysqli_fetch_array($qry2);
It looks like you include the comments.php into that last page <?php include('comments.php'); ?> So what I would do is where the query is above that I said to fix:
require_once `db.php`; //- create a separate file to do the DB connection for you
//then you can add that to the top of all the pages you need the DB for
include 'header.php'; //no need for the ( ) for any of the include* or require* calls.
/*
require will issue an error if the included file is not found
include will fail silently, for things that are required for your
page to work and not produce errors use require (like the DB)
for things you only ever include once, also like the DB stuff use *_once
then no matter how many *_once calls are stacked from including
the other page you don't have to worry about it.
as above those simple rules give us require_once for the DB.
the other pages I am not sure which would be best.
*/
//localize the movie ID - change any use of `$_GET['id']
$movie_id = isset($_GET['id']) ? $movie_id : false;
if(!$movie_id){
//do something if someone goes to this page with no ?id= in the URL
//you could redirect the page
//you could have a default movie id etc...
}
$statement = $con->prepare('select * from tbl_movie where movie_id=:movie_id');
$statement->execute(['movie_id' => $movie_id]);
$movie = $statement->fetch();
//dont forget to fix the other DB call and remove the MySqli stuff.
Above I suggest using a single file for the DB, in your case it can be quite simple,
db.php
<?php $con = new PDO('mysql:host=localhost;dbname=db_movie', 'root', '');
That is literally all you need then, at the very top of each page you use the DB, simply add this file
require_once 'db.php';
This way if you need to change the password or something like that, you can go to one place named in way that is easy to remember and change it. How it is now, you would have to dig though all your code to change it. In that page your including a file named header.php and it looks like from your MySQLi code that it may have some connection stuff in there. I would remove any MySQLi stuff there too. You want to keep the DB file separate as you may need to include it in the AJAX backend parts and any output from header.php would mess you up.
Summery
What I showed above is a simple example of what you need to do, in that AJAX call This may not be all you need to do, these are just the things that were obvious to me.
You don't have to worry about child comment's movie ID, as they inherit it from the parent comment, which wouldn't exist (on the page) if it had the wrong ID. In your current setup, I would still save it as part of the data. It's just you dont need it to get child comments if you know the parent (which you sort of have to know). I didn't add it into one thing that looked like it was for child comment. You can add it, but as I said above, it's not really needed.
Really the question is way to broad, why isn't my code working kind of question. The only reason I took the effort was that you also took the effort to provide well organized code that is relatively minimal.
So thank you for that.
The last suggestion I would make, is clean up the extra line returns in some of the SQL, and format the TABs a bit better. But that is just a readability issue, I am very picky about formatting my code and some of that could be related to creating an question on SO as it takes a bit of getting used the markdown they use.
Hope it helps you!
Update
thanks for your answer, I really dont know what i should post here and what i shouldnt, and the thing that i dont understand is that: i have a tbl_comment which stores all comments from user and this table include movie_id, and i have another tbl_movie which has movie_id as a primary key, how can i link the movie _id with the tbl_comment so that every comment is stored for a specific movie_id
I will try to explain the flow of your application, with an example. For the sake of this example lets say the movie id is 12 and our main page is www.example.com/movies?id=12:
Inserting a comment
User goes to a url with ?id=12
everything after the ? is called the query string
PHP knows to take the query string and populate the supper global $_GET
so in the main page your movie id is now $_GET['id']
We localize this (make a local variable) at the top of the page with some basic checks. $movie_id = isset($_GET['id']) ? $movie_id : false;
if movie id is set ?id=12 then put it in $movie_id
if its not www.example.com/movies then set $movie_id to false
this avoids some errors if someone goes to the page without that set
At the bottom of the page you include this file <?php include('comments.php'); ?> think of it like pasting that code into this place
In comments.php, which runs when it's included above,
if someone inserts a new comment (submits the form) weve added that same $movie_id into the form with this line
<input type="hidden" name="movie_id" id="movie_id" value="<?php echo $movie_id; ?>" />.
-So now when the form submits to add_comment.php which you need to put in the form's action.
<form method="POST" id="comment_form" action="add_comment.php" >
It will contain the id as $_POST['movie_id'] on that page. The $_POST['movie_id'] is basically the same as $_GET['id'] but the form method tells us its post instead of get. Typically Get is used to retrieve resources, Post is used to modify them.
When PHP runs the above piece of HTML it replaces the <?php echo $movie_id; ?> with it's value of 12 so you get this
<input type="hidden" name="movie_id" id="movie_id" value="12" />
Now On add_comment.php (where the form action takes us) we can take that $_POST['movie_id'] and add that to your SQL used to Insert the comment from the form in #4. into the Database.
INSERT INTO tbl_comment
(parent_comment_id, comment, comment_sender_name, movie_id)
VALUES (:parent_comment_id, :comment, :comment_sender_name, :movie_id)
As this is a prepared statement we have the place holder :movie_id in the SQL query. In PDO we can feed that to the PDOStatment object ($statement) you get back from $statment=$conn->prepare($sql) by calling it's execute method or $statement->execute([..other stuff here..., 'movie_id'=>$_POST['movie_id']]).
The query that runs looks like this after PHP is done with it
INSERT INTO tbl_comment
(parent_comment_id, comment, comment_sender_name, movie_id)
VALUES (0, 'foo', 'ArtisticPhoenix', 12) <-- see what I did there.
So you see we took the value from the original URL request, added it to our form and then we wait for user action to submit that form with the movie id embedded in it. The when the form submits it calls our add comment page, where we take it out of the Posted data, and feed it into the DB with the rest of the form data for that comment.
The other ones are exactly the same except in those we are using AJAX to submit the data so instead of a form we just add it to the AJAX call. I will give you an example of how that executes.
Showing a comment
This is the same up to #4 above
In comments.php you call load_comment(); "After" defining the function as it doesn't exist tell you do that, so you cant call it before.
This runs your AJAX request $.ajax, for the purposes of this example think of it like a fancy way to do a form. The url is the form action the method is well the method. The data is the form data, the dataType is the type of encoding in this case JSON or Javascript Object Notation. Which is a fancy way of saying structured data, as in PHP its basically an array (or data with nested elements).
The url (action) points us to fetch_comment.php, so when that runs our data: {movie_id : <?php echo $movie_id; ?>}, becomes data: {movie_id : 12}, which gets sent back to server where PHP sees it as $_POST['movie_id']
Similar to the Insert, we use that ID in our SQL query that pulls the parent comments
SELECT * FROM tbl_comment
WHERE parent_comment_id = :parent_comment_id AND movie_id = :movie_id
ORDER BY comment_id DESC
This says "Select all columns From table tbl_comment WHERE parent_comment_id IS 0 and Movie Id is 12" So it will only return comments for movie 12 that are also parents.
in your code you have just $statement->execute(); But you had the parent_comment_id hard coded as 0. This was fin until we needed to add the movie_id Once we did that it makes more senses to make it part of the prepared statement so it reads better. But like the insert, now we have place holder in place of values so we need to take that data and add it to execute for this query.
So $statement->execute(); becomes $statement->execute(['parent_comment_id'=>0, 'movie_id' => $_POST['movie_id']]); Or when PHP is done with it $statement->execute(['parent_comment_id'=>0, 'movie_id' => 12]); which the Database knows to use the keys to match the placeholders and it completes our query.
SELECT * FROM tbl_comment
WHERE parent_comment_id = 0 AND movie_id = 12
ORDER BY comment_id DESC
Then we take the results and send them back to the success handler for the AJAX with echo and in this case add it to the page with this line $('#display_comment').html(data);
So In conclusion
Your code:
load_comment();
function load_comment()
{
$.ajax({
url:"fetch_comment.php",
method:"POST",
success:function(data)
{
$('#display_comment').html(data);
}
})
}
Correct code (what I said):
//.. in your JS, add the movie id to the fetch comment call
function load_comment()
{
$.ajax({
url:"fetch_comment.php",
method:"POST",
data: {movie_id : <?php echo $movie_id; ?>},
dataType: 'json',
success:function(data){
//...
})
}
load_comment();
What you need to do
//$movie_id = $_GET['id'] in the main page that included this file.. #2 above
function load_comment()
{
$.ajax({
url:"fetch_comment.php",
method:"POST",
data: {movie_id : <?php echo $movie_id; ?>},
dataType: 'json',
success:function(data)
{
$('#display_comment').html(data);
}
});
}
load_comment();
When PHP completes the above code it sends this to the client (using 12 from our example)
//$movie_id = $_GET['id'] in the main page that included this file.. #2 above
function load_comment()
{
$.ajax({
url:"fetch_comment.php",
method:"POST",
data: {movie_id : 12}, //PHP takes the value of $movie_id and puts it here
dataType: 'json',
success:function(data)
{
$('#display_comment').html(data);
}
});
}
load_comment();
Above is what actually runs in the browser
That is pretty much the gist of it. As I said its more beneficial to you to learn how it works. Sure I can post the complete code but I have no way to test it, no way to know if that is all the errors or not. If you learn how it works, you will be better equipped to take on those challenges yourself. I would rather spend 3 or 4 times the effort teaching you how it all works, then to post some code that you have no idea how it works.
Hope that all makes some sense.
I got this error. And I can't find what was wrong with it. I am using PHP and javascript.
I have a hidden iframe below my code:
<iframe id="hidden_form_submitter" name="hidden_form_submitter" style="width:100%;height:1px;visibility:hidden"></iframe>
And I have this line of code, an action button in which the id of a row will send as URL parameter:
<tr bgcolor="#d1ffcf" class="row-<?=$transaction['id']?>">
<td>
<a class="done-btn" data-confirm="Are you sure?" href="?action=change&status=done&transact_id=<?=$transaction['id']?>" target='hidden_form_submitter' title="Click if matched!"> Done</a>
</td>
</tr>
Then lastly I have this code on top to update the row in my database:
<?
if($_GET['action'] == 'change'){
//update query here
echo "<script>window.parent.document.getElementsByClassName('row-{$get['id']}').style.backgroundColor='green';</script>";
exit;
}
?>
No problem on the updating side in my server.
The problem is the JavaScript wherein I want to change the bgcolor of all same class without reloading the whole page.
UPDATE: Cannot change the background of every class. Example, I have this parameter to be send. ?action=change&status=done&transact_id=1608
So all element with class row-1608 should change the background color or change something style.
Try changing this:
echo "<script>window.parent.document.getElementsByClassName('row-{$get['id']}').style.backgroundColor='green';'</script>";
To this:
echo "<script>";
echo "var allRows = window.parent.document.getElementsByClassName('row-{$get['id']}');";
echo "for (var i = 0; i < allRows.length; i++) {";
echo " allRows[i].style.backgroundColor = 'green';";
echo "}";
echo "</script>";
You need to iterate allRows and set the backgroundColor on each element.
(Inspired by this example)
I know that this question has been asked before,I have read the answer,implemented it,but I am facing one small problem.
In the PHP file I am trying to make an anchor tag and then display it in the popover,but instead making it clickable,the whole content(along with the anchor tag) is displayed.
Also,once the icon is clicked,it sticks around and doesn't go away even after clicking on it or anywhere else on the page.
Here is the code:
HTML file:
<li style="margin-left: 15px;">
<a href="#" data-placement="bottom" title="notifications" data-poload="notification_list.php" id="id-wala">
<img src="assets/ring.png" width="25" height="25" data-toggle="tooltip" data-placement="bottom" title="notifications">
</a>
</li>
AJAX code
$('*[data-poload]').click(function() {
console.log('Hey');
var e=$(this);
e.off('click');
e.unbind('click')
$.get(e.data('poload'),function(d) {
console.log(d);
e.popover({content: d}).popover('show');
});
});
PHP file
<?php
#The code for connecting to the database removed for clarity.
$sql1 = "SELECT PID from post where UID = '$a'";
$result1 = mysqli_query($conn,$sql1);
$end_result = '';
while($row1 = mysqli_fetch_assoc($result1)) {
$temp = $row1["PID"];
$sql = "SELECT * from comment where status = 'unread' and PID = '$temp' ";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_assoc($result)) {
$end_result='<a href ="#" >'.'Notification from '.$row["UID"].'</a>';
echo $end_result;
echo '<br/>';
}
}
}
$conn->close();
?>
The problem is that the echo $end_result is printing <a href ="#" >Notification from 89</a> instead of Notification from 89 and making it clickable.
Please provide some suggestions on how to fix this problem.
The issue is because by default the html property on the popover is false. This means any HTML you attempt to place inside the popover content will be removed. To change this behaviour you need to set html: true.
You'll also need to use trigger: 'manual' and use the toggle option to hide/show the popover on successive clicks. Try this:
e.popover({
html: true,
trigger: 'manual',
content: d
}).popover('toggle');

I'm trying to get records from the database using a client side (Javascript) clickable list. The problem is that I want the clickable links to be sourced from the data in the database in the first place (MySQL).
I'm having problems passing the data to create the clickable list. I've tried various ideas and hit stumbling blocks to do with client side and server side programming (and briefly looked into JQuery but it appears difficult to do). I've been attempting this with HTML, PHP, Javascript, JQuery (briefly) and MySQL.
So I need to SELECT post_id, post_title FROM posts and make post_title clickable in the list but using the associated post_id to find the relevant data in the DB and post this via innerHTML into another element. Any ideas?
index.php <- List
<html>
<head>
<script src="jquery.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<?php
$sql = 'SELECT post_id AS "id", post_title AS "title" FROM posts';
$posts = $mysqli->query($sql);
?>
<ul id="post_list">
<?php
foreach ($posts as $post) {
?>
<li><a href="#" data-id="<?php echo $post['id'] ?>"><?php
echo $post['title']
?></a></li>
<?php
}
?>
</ul>
<div id="post_content"></div>
</body>
</html>
script.js <- Interactivity (requires jquery)
$(document).ready(function() {
$('#post_list').on('click', 'li a', function() {
$('#post_content').load('get_post.php?id=' + $(this).data('id'));
});
});
get_post.php <- Selected post
<?php
if (!empty($_GET['id'])) {
$sql = 'SELECT * FROM posts WHERE post_id = '.$_GET['id'].'';
$res = $mysqli->query($sql);
if (($post = $res->fetch_assoc())) {
?>
<h1><?php echo $post['post_title'] ?></h1>
<p><?php echo $post['post_body'] ?></p>

} else {

Maybe I've not understand correctly, but this can solve your problem :
You need at least 2 files (3 if you separate the Js Code)
Index.php :
$arrayItems = array()//The array containing your datas from the database
echo '<div id="listItems">';
for($i = 0; $i < count($arrayItems); $i++){
echo '<div class="item" idFromDB="'.$arrayItems[$i]['post_id'].'">'.$arrayItems[$i]['post_title'].'</div>';
}
echo '</div>';
echo '<div id="containerDetailsItem"></div>';
javascript.js : (which is more Jquery)
$(document).ready(function() {
$('.item').live('click', function(){
$('#containerDetailsItem').load('myAjax.php?idItem='+$(this).attr('idFromDB'));
});
});
and the ajax File (myAjax.php) :
if(isset($_GET['idItem']) && $_GET['idItem'] != ''){
$idItem = (int)$_GET['idItem'];
//Get the infos from the database with the ID given
echo 'datas from BDD';
}
And I think that will do what you need. This is simple PHP with Jquery and Ajax.
PS : There is just minified code. You'll need to include Jquery (from google maybe) and to make the link between index.php and Javascript.js
i have a dynamic table that has a list of records, basically for all rows of the table there is a link to click, that passes the id of that row clicked to the next page,
my question is how can i save and display the number of times each link have been clicked ?
here is my code
<table width="100%" >
<tr bgcolor="#FF3399" style="color:#FFF">
<td><h3><strong>Topic</strong></h3></td>
<td><h3>Author</h3></td>
<td><h3>Date</h3></td>
<td><strong>Replies</strong></td>
<td><strong>Views</strong></td>
</tr>
<?php do { ?>
<tr bgcolor="#009900" style="color:#FFF">
<td><h4><a style="color:#FFF" onclick="spinn();" data-ajax="false" href="send.php?id=<?php echo $row_forum['id']; ?>"><strong><?php echo $row_forum['Topic']; ?></strong></a></h4></td>
<td bgcolor="#009900"><h4><?php echo $row_forum['Author']; ?></h4></td>
<td><h4><?php echo date("g : i a, j/F/Y,",strtotime($row_forum['Date'])); ?></h4></td>
<td> <?php echo $row_forum['Replies']; ?></td>
<td><?php echo $row_forum['Views']; ?></td>
</tr>
<?php } while ($row_forum = mysql_fetch_assoc($forum)); ?>
</table>
On the page that is the target of your link, simply invoke a method which will increase your count field in the database. You can put code like this in your target page:
<?php
function increaseCount() {
// ... connect to db
mysql_query('UPDATE table SET count=count+1 WHERE id='.$id);
}
increaseCount($_GET['id']);
?>
Please note, that the above code is very trivial and dangerous and only shows the concept. It does not protect you from SQL Injection at all. Doesn't even check, if the id parameter in the address exists.
Also, don't use methods like mysql_query - they're depracated.
Alternatively, try using Ajax to change the behavior of link's click event - send an ajax request to PHP script which will increment your count field in the database, and then follow your link's href :)
XmlHttpRequest
jQuery.ajax
Edit
$topicId = $_GET['id']; // you need to change 'id' to the name of your ID-parameter in the URL
$viewsIncrementQuery = "UPDATE `topic` SET `Views` = `Views` + 1 WHERE `id` = " . $topicID;
$incremented = mysql_query($viewsIncrementQuery, $epl) or die(mysql_error());
You need to put that code somewhere close to where you extract data from the database, so probably after the $query_lin = sprintf( (...) part.
If it throws an error - show it's message.
