Include Somtimes Doesn't Get Data

Recommended Posts

I'm working  with the include& bootstrap API in order to include content from a different PW installation in my main website.

It seems to work correctly, but sometimes (once per week) the page doesn't receive data
from processwire (All the images and text are not showing)

The only way I found to solve this is... login to the processwire admin page.

Instantly the API starts to work again.

This is the code I use:

                        function listPage($page, $level = 0) {
                            if($page->numChildren) {
                                foreach($page->children as $child) { 
                                <div class="6u">
                                    <div class="row">
                                        <div class="6u box240 boxtext bg-color-events">
                                            <h3><?php echo $child->title ?></h3>
                                            <p><?php echo $child->summary ?></p>
                                            <a class="scopri color-events" href="eventi?detail=<?php echo $child->name ?>"><span>scopri</span></a>
                                        <a href="eventi?detail=<?php echo $child->name ?>"> 
                                            <div class="6u box240 imghover color-events">
                                                    $cover = $child->cover->first();
                                                <img src="/news<?php echo $cover->url;?>" alt="Vai al dettaglio dell'evento">
                        <?php   }
                        }?> .....
Did it ever happen to you? Any ideas about the possible cause?

Hi jeve and welcome to the forums.

I really don't have much advice for you, but it would be good to know what version of PW you are running and also your PHP and MySQL versions.

Also are you using any PW caching options?

Any change you have a isLoggedin() check in the bootstrapped file that is expiring?

Could you show us all the code from your bootstrapped file. There were some selector issues in a recent dev version of PW when bootstrapped, but these have been solved in the latest version.

I am sure we can figure this out with a little more information.

In addition to what @adrian said above (it's true that without knowing how exactly your "include & bootstrap" code is set up this is very difficult to debug), you mentioned that logging in helps and things start working instantly. This really makes it sound like it could be related to caching, which is then disabled once you login.. or perhaps permissions, though those shouldn't matter at all for API use.

Just for the record, is this site hosted on your local machine or a remote server?

As a first step when debugging site issues you should always take a look at the error log files (/site/assets/logs/errors.txt) of both sites, in case that something went really wrong. Server logs (Apache logs mainly) may also uncover something of interest. Please let us know if there's anything strange there from roughly the times this has occurred.

Thanks for posting the full code. I can't see anything in there that looks like it might be causing the issues you are having, although you might want to sanitize that $_GET :)

I am curious if it ever works if you are logged out - ie are these pages all visible to guest users?

Also don't forget to less us know the PW,PHP, and MySQL versions that you are running.

the bug is visible now on the page

this is a public page available to everyone.

As you see the page now looks empty. I'm not logged in into admin but if I do it the page will work again for everyone.

PHP version 5.3.3 and Mysql

the full phpini is here http://fotosociality.it/test14/info.php

Processwire version is 2.3

About guest, what Adrian meant is that have you by any chance disabled guest view of the pages within the templates of these pages? Look under Access for the templates of the pages that are not working properly...See screenshot below..


Btw, normally not a good idea to publicly expose your php info like that :-)

I see that the html is not loaded fully since there are no </body> or </html> tags. The code seems to suddenly stop. Could it be that there is some error which is not visible on first sight, but it viewable in the source of the html?

Also the minimum requirements are: PHP 5.3.8 and MySQL 5.0.15.

@kongondo - thanks but the guest access is checked.

If I'd log in now, the page would be visible to everyone.

@arjen you are right: the page is not completely loaded, but the error log is empty. 

There are some javascript errors, I'm working to correct them.

The same errors occur when the page works correctly.

Please log-in so we can see the full page. If you want to share your details in a PM I'd be happy to take a look. From our POV it is only guessing to why the page stops loading.

      I want to make a small site, a one page site.
      And i have this idea about doing 2 to 3 diffrent template that i can load into the index / home page.

      I want to do this with an array so that i can keep creating more topics (with the template) id needed.
      <?php include('./head.inc'); // include header markup ?> <?php $children = $page->get('template=onecolmn|twocolumn, sort=sort'); foreach($children as $child) { include($child); } ?> <?php include('./foot.inc'); // include footer markup ?>  
      As you can see i have to template wish i want to control from the backend.
      I know include does not work this way, put what is my other option to make an array that loads the whole page on an other pages.

      Hi fellow developers!
      I want to implement following action:
      Admin-priviledged user uploads a spreadsheet file (with many sheets) When page is saved, back end generates repeater items from the sheets We can render spreadsheet data from the repeater field. Profit! Currently I'm trying to find a way to read the uploaded spreadsheet file. ProcessWire doesn't seem to have modules suitable for my needs, but external PHP Library PhpSpreadsheet sounds like it could do the job. However, I can't even try it, because I simply don't understand how I can refer to an external library!
      Folder structure:
      templates _func.php > where I want to refer to the library libraries PhpSpreadsheet bunch of *.php > what I want to refer to I have tried different things varying from their documentation to forum posts and PW API with no luck. I would prefer not to use Composer, since it seems kind of overkill for one library.
      Thanks in advance and have a great day!

      Hi there
      Basically I want to call code within a ProcessWire page that isn't used as a template. Example: www.mypwpage.com/myphpfile.php
      I have a working PW Website with a couple of pages like /artists, /releases, /videos etc. Now I need a page /download without any editable fields in the backend, just calling some PHP code (that was coded by another guy) containing a form that checks unique download-codes in a second database and starts the download of the desired file. The script is working fine right now as part of a static website, but since I built PW behind the site, this independent «Download Section» of the page doesn't work anymore.
      Right now I have the main file download.php as a page template on a newly created empty page called /download, so until now the form is working (wow). After sending the form containing the download-code, the file check_code.php in a subfolder /site/templates/download is called and that's where I get an error.
      Any help?
