Value Old Does Not Work Out When The Form Refreshes-CodePudding

I'm working with Laravel 5.8 and I wanted to add value old() so that when user fills out form and the form gets refreshes (if any error occured), the old value appears as value of input:

<div class="form-group">
    <label for="">Postal Code</label>
    <span class='text-danger'>*</span>
    <input type="text" class="form-control" name="post_code" value="{{ old('post_code',$member->mbr_post_code??null) }}">
</div>

But now the problem is, it does not show the Old value of user however the form input is filled once.

So how to solve this issue?

CodePudding user response：

You should use only {{ old('post_code') }} or you can update the code in this way old('post_code',$member->mbr_post_code ? $member->mbr_post_code : '') This is happening for NULL.
