Hi iedereen,

Is er iemand die weet wat de oorzaak kan zijn voor het blokkeren van text/event-stream request?

In WordPress gebruik ik een plugin om demo data te importeren, maar krijg ik de foutmelding:

Undefined index: demo in ...\soo-demo-importer\soo-demo-importer.php on line 205

De ontwikkelaar van de template zegt het volgende:
Quote:
The importer uses event-stream events to import demo content. But it seems your server doesn't support them well.


de volgende PHP instellingen heb ik al gewijzigd:

display_errors=on
error_reporting=22519
max_execution_time=40000
max_file_uploads=2000
max_input_time=40000
max_input_vars=2000
memory_limit=512M
open_basedir=""
post_max_size=100M
upload_max_filesize=100M
error_log="C:\Inetpub\vhosts\s02.unveil.nl\logs\php_errors\test.s02.unveil.nl\php_error.log"

Het script dat de data importeert ziet er als volgt uit:

$_POST['demo'] bestaat niet in je formulier / POST-request.

Maak van regel 205 eens:
Code (php)
PHP script in nieuw venster Selecteer het PHP script
1
$demo = $_POST['demo'] ?? null; //"?? null" toegevoegd

Waarschijnlijk werkt dit als je alle warnings enzo uit hebt staan (WordPress ontwikkelaars kijken meestal niet zo nauw ...). In ieder geval gebeurt dan precies hetzelfde: PHP maakt van de "Undefined index" dan gewoon een null (dat is wat die "?? null" hier ook doet: indien niet bestaand, dan null - alleen nu met voorbedachte rade). Dan komt ie in ieder geval voorbij deze regel (in de initiële GET), en hopelijk gaat het dan wel goed als je uiteindelijk het formulier ook echt POST.
