View Page:-查看页面：-

<form method="post" action="" enctype='multipart/form-data'>
  <input type="file" name="fileToUpload" id="fileToUpload">
                    
<div class="col-12 text-center tm-submit-container">
    <button type="submit" name="but_upload" class="btn btn-primary tm-btn-submit">Submit</button>
</div>
</form>

insertion Code:-插入代码：-

<?php
include("config.php");

if(isset($_POST['but_upload'])){
 
  $name = $_FILES['fileToUpload']['name'];
  $target_dir = "upload/";    // create a folder in a directory.
  $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

  // Select file type
  $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

  // Valid file extensions
  $extensions_arr = array("jpg","jpeg","png","gif");

  // Check extension
  if( in_array($imageFileType,$extensions_arr) ){
 
     // Insert record
     $query = "insert into images(images) values('".$name."')";
     mysqli_query($con,$query);
  
     // Upload file
     move_uploaded_file($_FILES['fileToUpload']['tmp_name'],$target_dir.$name);

  }
 
}
?>

View Image Code:-查看图片代码：-

<?php
    $sql = "select * from images";
    $result = mysqli_query($con,$sql);
    while($row = mysqli_fetch_array($result)){
          $image = $row['image'];
          $image_src = "upload/".$image; 
          <img src='<?php echo $image_src;  ?>' >;
    }
?>
