I've added "Required / Not Blank / Selection Made" validation on the image field, however when validation fails I note that the file name reference disappears from screen. When I then try to submit the form, having corrected the validation error, it tells me that I must select an image?
The field is set up like this:
<label for="newsIMG1">Main Photograph</label>
<input type="file" class="form-control-file" id="newsIMG1" name="newsIMG1" tabindex="5" value="<?php echo(ValidatedField("addnews_784","newsIMG1")) ?>" required>
I've re-uploaded that (add-news.php) but also attach it for your reference.
