adrian Posted March 4, 2019 Share Posted March 4, 2019 This is really weird - I have two site which are on the same server and are basically identical. For one site there is no problem, but the other one exhibits this weird bug. This is the version with the problem This is the one that works as expected There are no relevant hooks that I can think of. Can anyone see anything I might be missing or do we think this might be a weird bug? Link to comment Share on other sites More sharing options...
LostKobrakai Posted March 4, 2019 Share Posted March 4, 2019 Can you look at the settings of the field especially the one stateing if the field is single value or multi value? Link to comment Share on other sites More sharing options...

I have included those in the dumps above - note that outputFormat is set to "0" on both sites. This is the "Automatic (single item or null when max files set to 1, array of items otherwise)" option. It actually doesn't even help if I set the field to array or single item - the formatted version always returns null. Link to comment Share on other sites More sharing options...
Autofahrn Posted March 4, 2019 Share Posted March 4, 2019 Seems I'm not alone encountering strange issues with File fieldtype configured for single items. I'm not sure if my symptoms relate to this one, but they are similar weird (work on one site/situation, fail on others). On one multi-language site I've added a single file to the language template which holds a SVG of the flag. The SVGs retrieve correctly for one language, but exactly one SVG can't be retrieved if the user is running from another language (I can try to replicate if required). Did the same on another site (using the same code) where it works ok. This does not relate to the language setting itself, I also saw a similar behavior with the same field used on different pages (can't remember exactly). As my personal workaround I've switched those fields to always return an array, even if they only hold a single item. Happens across any PW 3 version I've encountered so far. 1 Link to comment Share on other sites More sharing options...
adrian Posted March 4, 2019 Author Share Posted March 4, 2019 Thanks for the confirmation @Autofahrn - I have had to set to return Array on other sites as well for no discernible reason. In this case, they are both multi-language sites, although in the case of the site that's not working, there is actually only one installed language - I wonder if that might be related?

Autofahrn Posted March 4, 2019 Share Posted March 4, 2019 IIRC, I also encountered this randomly on sites without language support. Link to comment Share on other sites More sharing options...
LostKobrakai Posted March 4, 2019 Share Posted March 4, 2019 It's strange that even the field by itself returns null here. It should normally be at least something. Link to comment Share on other sites More sharing options...

Agreed, and this is even weirder - look what happens when I call d($page->document_pdf->url); before the others - even the getUnformatted version is now broken.

matjazp Posted March 4, 2019 Share Posted March 4, 2019 I cant' replicate here... Sure there are no hooks on url method? 1 Link to comment Share on other sites More sharing options...
Robin S Posted March 4, 2019 Share Posted March 4, 2019 Very strange, I've never experienced such a thing before. A couple of ideas... 1. Any chance there is a name clash for "document_pdf" on $page - something setting a custom property named "document_pdf" on the $page object? 2. Does changing the field name to something different fix it? Then maybe change it back to the original name and check again. 1 Link to comment Share on other sites More sharing options...
adrian Posted March 4, 2019 Author Share Posted March 4, 2019 @matjazp - no hooks on url, but I think it's before that anyway, because even $page->document_url returns null which is very weird. @Robin S - I tried renaming but no luck. I have seen this on several sites over the years and typically don't have time / energy to post about it. I am surprised it's not reported by others more often, but I guess give that @Autofahrn has experienced it and not reported also indicates that maybe it's not that uncommon. I guess also, the maxFiles setting of 1 is not used as often as 0. Link to comment Share on other sites More sharing options...

As discussed above, I'm thinking that it is somehow related to multi-language features. I don't work on multi-language sites which might explain why I've never seen it across dozens of sites. 5 minutes ago, adrian said: I guess also, the maxFiles setting of 1 is not used as often as 0. I use this option on every site, but never with the "Automatic" option - I prefer to always set the formatted value manually to align with the max files.

Since I'm a software guy myself, I prefer reporting only if I am able to provide steps to replicate the issue. Since I couldn't find any rules for this one yet, so decided to stay quiet. Maybe not the best choice... Regarding the multi-language feature I probably can check If I had this on one of my single-language sites (easy, just check for single file fields set to return an array). 2 Link to comment Share on other sites More sharing options...

I know how this feels. I'm sure there is some core issue with the admin login that semi-regularly gives me CSRF errors when I attempt to log in but I haven't been able to isolate the conditions to reproduce it - my gut feeling is that it's something to do with an expired cookie. I'm always in a hurry when it happens so I just back button and resubmit the form. To get to the bottom of your issue I expect it could be traced by dumping within the chain of methods that get the data from the database and ultimately deliver the formatted value. But who has time for that when you're on a deadline? 2 Link to comment Share on other sites More sharing options...
adrian Posted March 5, 2019 Author Share Posted March 5, 2019 Ok, so I've done some tracing to see what is going on and it's because the files are being tagged as temporary. This is the key line: https://github.com/processwire/processwire/blob/649d2569abc10bac43e98ca98db474dd3d6603ca/wire/modules/Fieldtype/FieldtypeFile.module#L411 that is causing it to return null. When a file is added, it is initially set to temp: https://github.com/processwire/processwire/blob/649d2569abc10bac43e98ca98db474dd3d6603ca/wire/core/Pagefiles.php#L347 so I guess for some reason the file upload process didn't complete properly so the temp status (timestamp) wasn't updated. Thing is that the files are fully uploaded and there is nothing wrong with them. I just manually changed the created dates in the database, via Adminer of course ?, and now everything works as expected. @Robin S - you seem to be the expert in issue reporting these days - any thoughts on the best way to handle this to explain best to Ryan? 4 Link to comment Share on other sites More sharing options...

Aha, great that you have found the source of the issue. In terms of a bug report, I don't expect anything can be done to guarantee to always successfully remove the temp status in all circumstances - I guess there can always be upload glitches of one sort or another. But what would be helpful is to make sure that files with temp status are removed when a page is (re)loaded in Page Edit, so you are not scratching your head wondering why you can see an image in the field that isn't accessible from the API. The thing is, I thought this already happened, which is why if you upload an image then refresh without saving the image is removed from the field. So I suppose it could be a matter of working out why an image with temp status is remaining in the field and is not removed. 3 Link to comment Share on other sites More sharing options...
Autofahrn Posted March 5, 2019 Share Posted March 5, 2019 Ok, so this differs from my symptoms. I've rechecked some of my sites and saw my various workarounds and also have a single language site with single file field explicitly set to array return. On other sites I've used a different workaround, which also fixes my language flag issue. Setting output formatting on before accessing the image, otherwise the field returns PageImages array instead of PageImage, so my loop now looks like: $languages = wire('languages'); foreach($languages as $l) { $l->of(true); // ensure $l->svg_image returns a PageImage $imgUrl = $l->svg_image->url; Output formatting is obviously off for some reason for the default (first) language if current session is not on default language. Just realized that on my other site (where I use SVG flags on the language template) I've also switched the field return to Array. So maybe this is more deterministic than I thought and indeed probably related to multi language sites. Link to comment Share on other sites More sharing options...
adrian Posted March 5, 2019 Author Share Posted March 5, 2019 Well I discovered the reason for the temp status issue in this case. I recently made a change to my Custom Upload Names module to add the temp status after renaming the file - this is because a PW rename() call removes the temp status so I wanted it added back in case the page was never saved. The problem is that PW doesn't use the temp status when you have the field's "override existing files" option checked. So, I have updated my module to not add the temp status when the field uses the overwrite setting and now we're all good. The thing is though that I've seen this issue before I added this feature to that module and I've also seen it on sites where I don't use the module at all. I feel like something should still be reported, but at the moment I am not sure how to reproduce the problem without the module being the cause. Perhaps as @Robin S pointed out, temp files should be deleted on page edit, in case they weren't deleted on page save. Do you guys think that is worth a bug report / suggestion? Maybe another component to it is to ask Ryan why temporary files are included when getting unformatted - maybe that makes sense for internal needs, but I think it's confusing for the API to contain these images. Any thoughts? Link to comment Share on other sites More sharing options...

Without steps to reproduce I doubt Ryan could/would do anything about it. Might be best to wait until you notice it again in a situation where Custom Upload Names is not involved and raise an issue then. 1 hour ago, adrian said: Maybe another component to it is to ask Ryan why temporary files are included when getting unformatted - maybe that makes sense for internal needs, but I think it's confusing for the API to contain these images.

szabesz Posted March 5, 2019 Share Posted March 5, 2019 Regarding the temporary state, are we talking about this bunch of issues? https://github.com/processwire/processwire-issues/issues/650 https://github.com/processwire/processwire-issues/issues/42 https://github.com/processwire/processwire-issues/issues/41 If so, then this part of the core might need some refactoring. 1 Link to comment Share on other sites More sharing options...
adrian Posted March 5, 2019 Author Share Posted March 5, 2019 @szabesz - that is the temp status we are talking about. Given that @Robin S has started an issue on this, I will let him follow up. 1 Link to comment Share on other sites More sharing options...
cb2004 Posted March 5, 2019 Share Posted March 5, 2019 Could this be related? This is an image field set to have just 1 file. Will try getUnformatted when I get a mo. Link to comment Share on other sites More sharing options...

The Temp status column is the only thing that's new. 2 Link to comment Share on other sites More sharing options...
