I am setting few session variables in my search controller as below:
// Add the search form values to session too
session()->put('search-keyword', $keyword);
session()->put('search-geolocation', $geoLocation);
Later,
return view('search.index', compact('profiles'));
In my search blade template, have this line:
<div style="background-image:url( '{{ $profile['_source']['picture'] }}' )"></div>
I am using 'file' session driver and the above works very well until $profile['_source']['picture'] is null. When it is null, for some reason session variable search-geolocation is never set! As checked in the session file at storage/framework/sessions: ...."search-geolocation";N;s:9....
If I change the <div> above to <img>, everything again works beautifully, regardless of whether $profile['_source']['picture'] is null or not null:
<img src="{{ $profile['_source']['picture'] }}" alt="">
This same problem never happens with the session variable search-keyword, whether $profile['_source']['picture'] is null or not null; search-keyword appears as it should in the session file.
Right after setting the session in the controller, I get correct value when I echo:
echo session()->get('search-geolocation');
Also, this problem goes away when I debug the code (XDebug) and all the values are stored correctly in the session file as expected. So, debug is not of much help.
I have already worked around this problem but I am not confident about session anymore. Therefore, want to understand what's going on here. Have tried changing the session driver without any difference.
If $profile['_source']['picture'] is not set - that might cause a PHP error, and maybe that is resulting in the session not being set?
If you are using PHP7 try this:
<div style="background-image:url( '{{ $profile['_source']['picture'] ?? null }}' )"></div>
...
Thanks Laurence, I did think about the same thing. What I realize is that for some reason a resultant output like
<div style="background-image:url( )"></div>
is tripping something (it shouldn't, but looks like it is), because the following works (btw, the variable is set) -
<div style="background-image:url( {{ empty($profile['_source']['picture']) ? 'Test' : $profile['_source']['picture'] }} )"></div>
(which in the end results into
<div style="background-image:url( Test )"></div>
for the null values).
I read somewhere that helpers like dd interrupts the session storage. Could it be something similar happening when the blade is being compiled? I don't see any errors though in the logs or otherwise. Also, it baffles me as to why <img> would work regardless and <div> not. There cannot be a connection between php and html syntax but perhaps there is something during blade compilation.
