Image not deleting from folder, i have two if statement but just one else statement so it looks like i am missing something but i really don't know what i am missing.
This is form:
<div class="form-group">
<label>Address</label>
<input class="form-control" type="text" name="pAddress" value="<?php echo $row1['p_address'];?>">
</div>
<div class="form-group">
<label>Thumb Image</label>
<input type="file" name="new_image" class="form-control">
<input class="form-control" type="hidden" name="pimage" value="<?php echo $row1['p_thumb_image'];?>">
<img class="float-left" src="<?php echo $row1['p_thumb_image'];?>" width="100px;"><br><br>
</div>
<div class="form-group text-center">
<input class="btn btn-primary" type="submit" name="update" value="Update">
</div>
</form>

You don't have a code that delete the files in php there's a function called unlink where you can delete a files but first you need fetch the path or filename and delete it before updating your data.
Here is the link of unlink.
