I don’t see that error on your site now. I do see many messages saying the variable `r` is not defined, which seems to be caused by the fact that you’re trying to read it on line 204 but are only writing it at line 217.

Hi Edwin . The fetch routine is failing as my artwork is not getting written please see my other thread its as if the 'c; routines fopen, fwrite etc are not working re there different alternatives on your server as my last server was Unix based. I use digital DSP to punch the sound so its rich as possible and represents in the best light.
Umm what does Gradle do please. I didn’t understand Hugs D
---
I don’t understand what is gradle too. My basic is pascal delphi c, vb.
Situation make to learn. When learn i understand much. Bcz it’s like delphi vb + c.
Not many different. Android is like them + xml + grant permissions.
file project is rearrange is commonly same. Activities manifest including gradle. Watching them as a part file structure of android project.
Gradle surgery is a nightmare. 🦍

Well I am checking through to see why its not fetching . It doesn’t seem to be running my script any ideas please as my site [http://www.deniserose.epizy.com/music\_now\_playing.php](http://www.deniserose.epizy.com/music_now_playing.php) contains
`.` This used to be ok so I am unsure why it doesn’t run now ?

Change all of those single quotes to double quotes. Single quotes in attributes are not valid HTML.
Also, check the F12 tools for any errors about that file.
---
thanks Wacky but it doesn’t seem to be running AJAX even with the double quotes in place . I even tried placing it into the main php function
```auto
InitReload() {
new Ajax.PeriodicalUpdater("track_data", "fetch_sql.php", {
method: "get", frequency: 10000, decay: 1});
}
```
It doesn’t seem to want to run it any ideas ?
As its not running here either on main page ?
Am not getting any loads in the F12 debugger either .

Does it supposed to be type=‘text/javascript’
or type=‘javascript’

Thanks but I think the problem is the page references have changed from my previous system i was on i was using
```auto
var base64file2 = $("img#np_track_artwork").attr("src", "data:image/png;base64,"+data);
```
To get the image base64 for the iage but dont think this working

Hi Edwin yes but this was all working before :
```auto
var image = document.createElement("img");
image.src = 'http://www.deniserose.epizy.com/images/nowplaying_artwork_2.png';
var base64file1;
toDataURL('/images/nowplaying_artwork_2.png', function(data) {
.then(dataUrl => {
console.log('RESULT:', dataUrl)
base64file1 = dataUrl;
});
//image.remove();
var base64file2 = $("img#np_track_artwork").attr("src", "data:image/png;base64,"+data);
```
but not now this is far as I got today 🙂

Thanks Edwin I have tried that in past without luck here I just need two base64file 1&2 for on screen and one in file. This code above no longer works on my new site . I wonder if CanvassElements are not available on this server as both in f12 debugger give void data or something about missing ) and or Uncaught SyntaxError: Unexpected token ‘.’ (at fetch\_updater.js:78:6)
---
Edwin in my js I have:
```auto
const toDataURL = url => fetch(url)
.then(response => response.blob())
.then(blob => new Promise((resolve, reject) => {
const reader = new FileReader()
reader.onloadend = () => resolve(reader.result)
reader.onerror = reject
reader.readAsDataURL(blob)
}))
```
then to handle it
…
var image = document.createElement(“img”);
image.src = ‘[http://www.deniserose.epizy.com/images/nowplaying\_artwork\_2.png](http://www.deniserose.epizy.com/images/nowplaying_artwork_2.png)’;
```
var base64file1;
toDataURL('/images/nowplaying_artwork_2.png', function(data) {
then(dataUrl => {
console.log('RESULT:', dataUrl)
base64file1 = dataUrl;
});
```
…
but this is not working as it did before in Java Script it has to be in JavaSript hugs
---
I think i got to bottom of it its a syntax error missing ‘,’ can you spot it ?
```auto
toDataURL("/images/nowplaying_artwork_2.png", function(data) {
then(dataUrl => {
console.log('RESULT:', dataUrl);
base64file1 = dataUrl;
}
});
```
