jDownloads Support Forum

Hello!
I had activated the "Compact Files layout with Checkboxes 3.9" plugin to allow downloading multiple files at the same time. In this version 4.1.3, the "Select all files" button appears but doesn't select any files. How do I get it working again?
Thanks

Hi,
I reproduced your result so I tried 'ticking' each individual box (select-all-files01.png). After clicking on the Continue button it listed the set of files in a Summary View as expected (select-all-files02.png).  Next pressed the Download Button. This gave a 404 error 'Requested page cannot be found' (select-all-files03.png).

Hi, thank you for testing!
In my case I am running Joomla 5.4.5 + jD 4.1.3. The checkbox "Select all files" was not working (neither select-all nor individual checkboxes were functional), but after applying the JavaScript workaround described below, both selecting files and downloading (including the ZIP package) work correctly — no 404 error.
So it seems there are actually two separate bugs:
1.    Checkbox bug (Joomla 5 + PHP 8.x) — onclick attributes on both the toggle and individual checkboxes are malformed in the generated HTML (value onclick= instead of two separate attributes), so the handlers never fire and boxchecked stays empty.
2.    404 on Download — which you reproduced on Joomla 6.1 but I cannot reproduce on Joomla 5.4.5.
Workaround for bug #1 (add to the "User After layout" field of the active checkbox Files layout):
html
<script>
document.addEventListener('DOMContentLoaded', function () {

    window.istChecked = function(isChecked, catid) {
        var boxchecked = document.querySelector('input[name="boxchecked"]');
        if (!boxchecked) return;
        if (isChecked) {
            boxchecked.value = 1;
        } else {
            var anyChecked = document.querySelectorAll(
                'input[name="cb_arr[]"]:checked'
            ).length > 0;
            boxchecked.value = anyChecked ? 1 : 0;
        }
    };

    window.checkAlle = function() {
        var toggle = document.querySelector('input[name="toggle"]');
        if (!toggle) return;
        var isChecked = toggle.checked;
        document.querySelectorAll('input[name="cb_arr[]"]').forEach(function(cb) {
            cb.checked = isChecked;
        });
        var boxchecked = document.querySelector('input[name="boxchecked"]');
        if (boxchecked) boxchecked.value = isChecked ? 1 : 0;
    };

    document.querySelectorAll('input[name="toggle"]').forEach(function(t) {
        t.addEventListener('change', checkAlle);
    });

    document.querySelectorAll('input[name="cb_arr[]"]').forEach(function(cb) {
        cb.addEventListener('change', function() {
            istChecked(this.checked, 160);
        });
    });

});
</script>

Clearly there is some missing code.
In my opinion the code you have defined should be included within jD itself, not in the Use After Layout section of the  "Compact Files Layout with Checkboxes v3.9".  There maybe other cases in other layouts so I will look at these.
Best wishes

This is also a 'challenge' with layout "Standard Files Layout with Checkboxes" as expected.  So any correction code really does need to be in jD itself

Thank you ColinM for investigating this further and confirming the root cause. I'm glad the workaround helped identify the issue. Looking forward to the fix in a future version!
Best regards,
Lina

Have also tried with layout Standard Files Layout with Checkboxes v3.9
It has the same problem.

Thank you

Hi Lina,
thank you for reporting this and for the helpful workaround.

We were able to reproduce the problem and found two issues in the legacy checkbox download flow. Both have now been fixed for the upcoming 4.1.4 version.

I will send you a PM with a 4.1.4 test package so you can check whether both the Select all function and the download link now work correctly in your setup.

Hi Lina,
Unfortunately, the bug hasn't been fully fixed yet. Sorry about that. So you don't need to test the version I sent you. I'll send you a new one today.

Thank you, Arno

Best regards,
Lina

Hi Arno,
I cannot see any attachment or download link for version 4.1.4 in the message.
Could you please send the package or the download link?
Thanks.

Hi Lina,
I sent you that version as an attachment to a private message. Not here in this thread.

But I've already released that version in the meantime, so you can install it in the usual way.  ;)

Hi Arno,
I've already tried the new version and I don't think it's working without using the code in Use After Layout. The "Select all files" button doesn't select any files.

Either you don't have the latest version installed, or you should clear your browser cache and try again.

You're also welcome to see it working successfully for yourself on
the demo installation. See pics.

Hi Arno,
Thank you for the screenshot. I notice in your demo the layout looks different from mine.
I tested all three checkbox layouts available in jDownloads 4.1.4:

Compact Files Layout with Checkboxes v3.9
Standard Files Layout with Checkboxes v3.9
Standard Bootstrap 5 Files Layout - Minimal Compact with Checkboxes v4.1

In all three cases, the "Select all files" button appears at the top of the list (not the bottom as in your demo), and clicking it does not select any files — it only changes its own appearance.
Could you please verify if the fix in 4.1.4 covers these layouts as well?
I also checked my Content-Security-Policy headers and they only contain frame-ancestors 'self' — so CSP is not blocking inline JavaScript in my case.
Environment: Joomla 6.1.0 + PHP 8.5 + jDownloads 4.1.4.
Thank you!
Lina

Hi
I am still having the same problem as LinaG.  I have cleared my browser cache.
ColinM

Hm.. strange.
I'll try to reproduce the error.

The Select all files tick box is not working. Have tried with layouts:
Compact Files Layout with Checkboxes v3.9
Standard Files Layout with Checkboxes v3.9
Standard Bootstrap 5 Files Layout - Minimal Compact with Checkboxes v4.1

Using Joomla 6.1.0 and jDownloads 4.1.4 Stable (15-05-2026)
Aware that it does work on the Test Site

Hi,
The fact that it works on jd40 suggests that it's running on a 'clean' installation without any legacy issues or overrides, and that the checkbox logic is therefore working as expected.

Please check that you have also enabled the correct category layout. That is where the main checkbox is displayed. See screenshot.

To quickly narrow down affected installations, please check these point:
- Check in the browser DevTools which JavaScript file is actually being loaded (including path and modification time/cache status). 
you can post the results of these point here (include a short screenshot from DevTools). We can then pinpoint exactly where your installation differs.
