Can't import bibtex files w/ php7.

[maladd]

Is anyone else having problems importing bibtex files since upgrading to Joomla 3.9 and using php 7+?

This is the error I receive

Call to undefined function split()

The problem seems to w/ Bibtex.php

Hi @maladd, still having issues? Can you please provide your exact version of PHP?

I am using php 7.3.5 on my development server and the production server is still on 7.2.18.

I typo'd - my production server is using php5.6. The latest version of php the production server can use is 7.2.18. I can't move my site off php5 until Jresearch works.

I am developing a site design that will run on php7.2, and we use JResearch for our staff pages and publications site.

Thanks for your efforts!

I redownloaded the latest build and installed it. I made the following changes to the BibTex.php file and my bibtex file uploaded almost successfully.

administrator/components/com_jresearch/includes$ diff BibTex.php-orig BibTex.php
421c421
< $arr = split('{', $entry);

        $arr = explode('\{', $entry);

630c630
< $authorarray = split(' and ', $entry);

    $authorarray = explode(' and ', $entry);

642c642
< $tmparray = split(' |~', $author);

            $tmparray = explode(' |~', $author);

The Type appears as in the Backend as JRESEARCH_ARTICLE{CHHATWAL2019. The value for pubtype in the database is "article{chhatwal2019". The line in the BibTex file is "@Article{Chhatwal2019a,", so the process cut the tailing character off the end of the citekey, as well as failing to put in the correct field. Not a big deal, but I notice it also lowercased the citekey from the original text.

Any thoughts?

Got it. Remove the escape from line 421.

$arr = explode('{', $entry);

Pubs now upload as expected.
