Hey there!!!

Im trying to attach image upload to bootstrap card(home.php) as well place the image in gallery(gallery.php). When I hit submit Im taken to a blank page instead of seeing image displayed on home page. Here is my code:

```
   <div class="modal-body">
       <form action="upcontent.php" method="post" enctype="multipart/form-data">
  Upload Image
   <input type="file" name="image" id="image"> 
   <div>
<textarea name="comments" id="comments" style="font-family:sans-serif;font-size:1.2em;">
</textarea>
</div>  
   <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>       
  <input type="submit" value="Submit" name="submit">
</form>
<div class="row row-cols-1 row-cols-md-2 g-4">
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);     
$mysqli = new mysqli("'');
$query =  "SELECT username,comment,image FROM tbl_member ORDER BY ID DESC";
$result = $mysqli->query($query);

//  Loop thru comments and display all of them
while($row = $result->fetch_array(MYSQLI_ASSOC) ) {
    printf("%s (%s)\n", $row["username"], $row["comment"],$row["image"]); 
?>
    <div class="col">
        <a href="pro.php">
            <div class="card">
                 <img src="<?php echo $fetch['location']?>" class="card-img-top" alt="...">
	        <div class="card-body">
                    <h5 class="card-title"><?php echo $row["username"];?></h5>
                    <p class="card-text"><?php echo $row["comment"];?></p>
                </div>
            </div>
        </a>
    </div>
</div>
<?PHP
}
?>
 
```

```
<?php
	require_once 'conn.php';
	
	if(ISSET($_POST['upload'])){
		$image_name = $_FILES['image']['name'];
		$image_temp = $_FILES['image']['tmp_name'];
		$image_size = $_FILES['image']['size'];
		$ext = explode(".", $image_name);
		$end = end($ext);
		$allowed_ext = array("jpg", "jpeg", "gif", "png");
		$name = time().".".$end;
		$path = "img/".$name;
		if(in_array($end, $allowed_ext)){
			if($image_size > 5242880){
				echo "<script>alert('File too large!')</script>";
				echo "<script>window.location = 'home.php'</script>";
			}else{
				if(move_uploaded_file($image_temp, $path)){
					mysqli_query($conn, "INSERT INTO `image` VALUES('', '$name', '$path')") or die(mysqli_error());
					echo "<script>alert('Image uploaded!')</script>";
					echo "<script>window.location = 'home.php'</script>";
				}
			}
		}else{
			echo "<script>alert('Invalid image format!')</script>";
			echo "<script>window.location = 'home.php'</script>";
          echo "<script>window.location = 'gallery.php'</script>";
		}
		
		
	}
?>
```

Hey all ;) 

I took on an already made script for image gallery..goal is to have images uploaded within home page form a gallery for the user( think of FB..each member has their own pic gallery created from what was uploaded either on the dash or profile page). Again I want to make sure the images uploaed from the dropdown button not only shows up underneath on the home page but on image gallery page. 

Thank ya :) 

File upload code from Home page:
```
 <div class="dropdown">
  <button onclick="myFunction()" class="dropbtn">Upload Photo/Text</button>
  <div id="myDropdown" class="dropdown-content">
     <form action="upcontent.php" method="post" enctype="multipart/form-data">
  
  <input type="file" name="fileToUpload" id="fileToUpload">
   <br><br>     
     Words: <textarea name="comment" rows="5" cols="40"><?php echo $comment;?></textarea>
   <input type="submit" value="Submit" name="submit">
</form>
  </div>
</div> 
```
Code from gallery page
```
<div class='container'>
            <div class="gallery">
              
            <?php 
            // Image extensions
            $image_extensions = array("png","jpg","jpeg","gif");

            // Target directory
            $dir = 'img/';
            if (is_dir($dir)){
                
                if ($dh = opendir($dir)){
                    $count = 1;

                    // Read files
                    while (($file = readdir($dh)) !== false){
