Trouble closing if statement and while loop in PHP - php

Question

I'm trying to display some html inside a php "if statement" and during a "While" Loop.
I keep getting unexpected end of file error and I know there are two braces missing but I can't see where to close the while loop properly.
I'm still new to coding so please be gentle... :-)
tried php syntax checker and other similar posts here
<?php include 'includes/header.php';?>
<!-- Navigation -->
<?php include 'includes/navbar.php';?>
<?php
if (isset($_GET['post'])) {
$post = $_GET['post'];
if (!is_numeric($post)) {
header("location:index.php");
}
}
else {
header('location: index.php');
}
$query = "SELECT * FROM posts WHERE id=$post";
$run_query = mysqli_query($conn, $query) or die(mysqli_error($conn)) ;
if (mysqli_num_rows($run_query) > 0 ) {
while ($row = mysqli_fetch_array($run_query)) {
$post_title = $row['title'];
$post_id = $row['id'];
$post_author = $row['author'];
$post_date = $row['postdate'];
$post_image = $row['image'];
$post_content = $row['content'];
$post_tags = $row['tag'];
$post_status = $row['status'];
$img_ext = explode(".", $post_image);

Try below:
<?php include 'includes/header.php'; ?>
<!-- Navigation -->
<?php include 'includes/navbar.php'; ?>
<?php
if (isset($_GET['post'])) {
$post = $_GET['post'];
if (!is_numeric($post)) {
header("location:index.php");
}
} else {
header('location: index.php');
}
$query = "SELECT * FROM posts WHERE id=$post";
$run_query = mysqli_query($conn, $query) or die(mysqli_error($conn));
if (mysqli_num_rows($run_query) > 0) {
while ($row = mysqli_fetch_array($run_query)) {
$post_title = $row['title'];
$post_id = $row['id'];
$post_author = $row['author'];
$post_date = $row['postdate'];
$post_image = $row['image'];
$post_content = $row['content'];
$post_tags = $row['tag'];
$post_status = $row['status'];
$img_ext = explode(".", $post_image);
?>
<!-- Page Content -->
<div class="container">
<div class="row">
<!-- Blog Post Content Column -->
<div class="col-lg-8">
<!--First Post -->
<hr>
<p>
<h2><?php echo $post_title; ?></h2></p>
<p>
<h3>by <?php echo $post_author; ?></h3></p>
<p><span class="glyphicon glyphicon-time"></span>Posted on <?php echo $post_date; ?></p>
<hr>
<?php if ($img_ext == "mp4"): ?>
<video controls width="400" height="300">
<source src="allpostpics/<?php echo $post_image; ?>" type="video/mp4">
Video tag is not supported in this browser.
</video>
<?php else : ?>
<img class="img-responsive img-rounded" src="allpostpics/<?php echo $post_image; ?>"
alt="900 * 300">
<?php endif; ?>
<hr>
<p><?php echo $post_content; ?></p>
</div>
<!-- Blog Sidebar Widgets Column -->
<div class="col-md-4">
<?php include 'includes/sidebar.php'; ?>
</div>
</div>
<!-- /.row -->
<hr>
<!-- Footer -->
<?php include 'includes/footer.php'; ?>
</div>
<!-- /.container -->
<!-- jQuery -->
<script src="js/jquery.js"></script>
<!-- Bootstrap Core JavaScript -->
<script src="js/bootstrap.min.js"></script>
</body>
</html>
<?php
} // End while
} // End if
Note: your code was missing <?php endif; ?> and two braces at the end.

PHP is syntatically more similar to C than to Python or VisualBasic. Indentation means nothing here. Code blocks need to be explicitly open and closed.
There are 2 types to quote the if-else blocks but you did neither of those.
You can either:
use brackets if { ... } else { ... }
Example:
<?php if ($img_ext=="mp4") { ?>
<video controls width="400" height="300">
<source src="allpostpics/<?php echo $post_image; ?>" type="video/mp4">
Video tag is not supported in this browser.
</video>
<?php } else { ?>
<img class="img-responsive img-rounded" src="allpostpics/<?php echo $post_image; ?>" alt="900 * 300">
<hr>
<p><?php echo $post_content; ?></p>
<?php } ?>
use colon and keyworkds if, endif
Example,
<?php if ($img_ext=="mp4"): ?>
<video controls width="400" height="300">
<source src="allpostpics/<?php echo $post_image; ?>" type="video/mp4">
Video tag is not supported in this browser.
</video>
<?php else: ?>
<img class="img-responsive img-rounded" src="allpostpics/<?php echo $post_image; ?>" alt="900 * 300">
<hr>
<p><?php echo $post_content; ?></p>
<?php endif ?>
Just chose which one to go for.
Similarly, you have to close your while-loop with either bracket } or endwhile, depends of your syntax of choice.

Answer 3

you opened the if statement and forgot to close it also while is not closed closed it after the container gets closed
