PHP Button onclick=“this.disabled=true” unset if page refresh

[aveeva]

I dont want unset onclick="this.disabled=true" if page refresh,

code :

 

<button type="button" class="addb btn btn-primary rounded-pill py-2 btn-block" type="submit" data-voice_sku="'.$row["voice_sku"].'" data-voice_name="'.$row["voice_name"].'" onclick="this.disabled=true">Add to Playlist</button>

 

If page refresh onclick event unset. how to prevent?

The onclick will still work after a refresh.

Are you saying that you want disabled buttons to remain disabled after a refresh?

Keep in mind that PHP is stateless. That means each time the page is output by the server it is as if it is the first time and nothing about what happened on that page previously is known. What Barand is trying to get at, is whether or not you need to use a session variable to keep track of the state of that button.
