Display image from MySQL using PHP not working - php

Question

I have an upload image to database code like this:
<form method="post" action="quanly.php" class="form-group justify-content-center" enctype="multipart/form-data">
<div class="custom-file mb-3">
<input type="file" class="custom-file-input" id="image" name="image">
<label class="custom-file-label" for="customFile">Choose file</label>
</div>
<div class="col text-center">
<button type="submit" name="submit" id="add_btn" class="btn btn-primary mb-2"> <i class="fas fa-plus"></i>Submit</button>
</div>
</form>
And the PHP code:
$image = addslashes($_FILES['image']['name']);
$query = "INSERT INTO tasks (image) VALUES ('$image')";
mysqli_query($db, $query); //db is the mysql connection
Everything upload works just fine, but I have some code to display image using Bootstrap 4 modal
<?php $i = 1; while ($row = mysqli_fetch_array($tasks)) { ?>
<button type="button" class="btn btn-primary btn-sm " data-toggle="modal" data-target="#imagemodal<?php echo $row['id'];?>" <?php if (empty($row['image'])) { echo "disabled"; } ?> ><i class="fas fa-image"></i></button>
<!-- IMAGE MODAL BEGIN -->
<div class="modal fade" id="imagemodal<?php echo $row['id'];?>">
<div class="modal-dialog">
<div class="modal-content">
<!-- Modal Header -->
<div class="modal-header">
<h4 class="modal-title">Xem ảnh/ đính kèm</h4>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<!-- Modal body -->
<div class="modal-body">
<?php echo '<img src="data:image/jpeg;base64,'.base64_encode( $row['image'] ).'"/>'; ?>
</div>
<!-- Modal footer -->
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<!-- IMAGE MODAL END -->
<?php $i++; } ?>
Which image of rows showing a small image square (error), when I view the image url, it's something like this: data:image/jpeg;base64,ei5wbmc=

Answer 1

Store and upload image in folder code
<?php
if(isset($_POST['but_upload'])){
$name = $_FILES['file']['name'];
$target_dir = "upload/";
$target_file = $target_dir . basename($_FILES["file"]["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
$query = "insert into images(name) values('".$name."')";
mysqli_query($con,$query);
// Upload file
move_uploaded_file($_FILES['file']['tmp_name'],$target_dir.$name);
}
}
?>
<form method="post" action="" enctype='multipart/form-data'>
<input type='file' name='file' />
<input type='submit' value='Save name' name='but_upload'>
</form>
Show in display view.
<?php
$sql = "select name from images where id=1";
$result = mysqli_query($con,$sql);
$row = mysqli_fetch_array($result);
$image = $row['name'];
$image_src = "upload/".$image;
?>
<img src='<?php echo $image_src; ?>' >
