Change pagetitle from within a plugin.

This will be my first post, I'm new to the MODx world \o/.

I am trying to build my first plugin. From within the plugin... this works:

$resource->set('alias', 'Something here');

This does not:

$resource->set('pagetitle', 'Some other stuff here');
$resource->set('longtitle', 'Some other stuff here');
$resource->set('description', 'Some other stuff here');

Why? Is there any difference?

I tried attaching to "OnDocFormSave" and "OnBeforeDocFormSave".

Thank you all

after setting the fields?

Thanks Bruno for your help on this one (and many others in this Forum).

The problem is not the "$resource->save()", this is not needed.

This line

$resource->set('alias', ...

gets applied instantly, with no need to refresh the page.

But in this one

$resource->set('pagetitle', ...

there is a need to refresh the page :S

With the save it behaves the same way.
Is this normal? Can I apply immediately without the need to refresh?

Thanks,
António

Try OnDocFormSave end add ->save() to the end.

Maybe I'm being dense, but your question is not clear to me. Are you trying to update the display on the Manager page, the data in the database, or both?

MODX used two refresh the Manager page after the user saved the resource, but it you want to do that now, it's a little tricky. You have to hijack the save button with some JS code (credit to Gary Nutting):

 $modx->regClientStartupHTMLBlock('
        <script type="text/javascript">
            Ext.override(MODx.panel.Resource, {
                originalSuccess: MODx.panel.Resource.prototype.success
                , success: function (o) {
                    this.originalSuccess(o);

                    var stageDateTv = document.getElementById("tv' . $stageDateTvId . '").value;
                    var stagedResourceTv = document.getElementById("tv' . $stagedResourceTvId . '").value;

                    if (!!stageDateTv && (!stagedResourceTv || !stagedResourceTv.length)) {
                        var url = location.href, i = url.indexOf("?") + 3;
                        MODx.loadPage(url.substr(i));
                    }

                }
            });
        </script>');

Thanks "FerX" but it's the same result: it updates the "Resource Alias" field instantly, but it does not update "Title" field.

It does update the "Title" in the database, because if I refresh the page the field changes.

Thanks a lot Bob, this code will be helpful in the future... good way to learn the "inside guts" of Modx.

But what I want is precisely to avoid the need of refresh: updating the form field "Title" instantly on plugin code execution.
The form field "Resource Alias" is updated instantly (with some JS somewhere), but "Title", "Long Title"... are only updated on the database. To view the field changes, I need to refresh the page... and I want to avoid that.

Is it a bug or a feature?
I'm using 2.5.7

I think that will be pretty difficult. Your plugin is executing on the server, but the fields you want to update are on the client's browser. You update the fields in the DB, but the browser isn't aware of that unless the page is reloaded.

To communicate with the browser, you'd have to use JavaScript, but the JS would have to be created and injected when the Manager page is loaded and rendered, not when the save button is clicked. At that point, you probably don't know the new values for the pagetitle and longtitle (if you did, you'd do everything in a earlier event like OnDocFormPrerender).

The only thing I can think of that might do it is a custom processor that you call with AJAX by registering an onClick() function for the Save button with addEventListener(). The processor would somehow get the new values (from a file written by the plugin or the DB), then return them. You'd need the processor to wait until the data was available. The AJAX call's success() function could update the fields on the screen.

It works for the alias, because the new alias is returned via the connector in the AJAX response from the resource/update processor. The pagetitle and longtitle are not returned.

I would just reload the page. wink

Thanks for the clear explanation. It makes sense now.

Yes, I will happily keep reloading, because this CMS has so many good things wink
