Steps to reproduce

  1. Open the Relation View of a table
  2. Save your settings

Expected behaviour

The Foreign key constraints should be saved without error.

Actual behaviour

I get a error message in phpmyadmin
Error in processing request Error code: 500 Error text: error (rejected) It seems that the connection to server has been lost. Please check your network connectivity and server status.

and an error in the nginx log
2018/02/14 11:26:34 [error] 1050#1050: *3617 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Cannot unset string offsets in /opt/phpmyadmin/libraries/classes/Table.php:2307 Stack trace: #0 /opt/phpmyadmin/libraries/classes/Controllers/Table/TableRelationController.php(252): PhpMyAdmin\Table->updateForeignKeys(Array, Array, Array, Array, Array, 'duplicity', Array) #1 /opt/phpmyadmin/libraries/classes/Controllers/Table/TableRelationController.php(126): PhpMyAdmin\Controllers\Table\TableRelationController->updateForForeignKeysAction() #2 /opt/phpmyadmin/tbl_relation.php(70): PhpMyAdmin\Controllers\Table\TableRelationController->indexAction() #3 {main} thrown in /opt/phpmyadmin/libraries/classes/Table.php on line 2307" while reading response header from upstream, client:, server:, request: "POST /tbl_relation.php HTTP/2.0", upstream: "fastcgi://unix:/run/php/php7.1-fpm.sock:", host: ""

On another server with the same setup and the phpmyadmin version 4.2.12deb2+deb8u2 it works fine without errors.

* Fixes error in foreign key sql genration, issue #14030
The destination_column_names were getting passed as a 1d array, the names when extracted gave a string. Passing it as a 2d array (see templates/table/relation/foreign_key_row.twig lines 123,133) fixes the issue.
