Title: Problems with Plugin “TablePress” Last modified: December 23, 2022 --- # Problems with Plugin “TablePress” * Resolved [reasonx](https://wordpress.org/support/users/reasonx/) * (@reasonx) * [3 years, 5 months ago](https://wordpress.org/support/topic/problems-with-plugin-tablepress/) * Tested on: - WordPress 6.1.1 - plugin load filter 4.0.12 (and older versions) - TablePress 2.0 (and older versions) * problem description: * you can not insert images into table cells because plugin load filter interferes in the ajax call. If you deactivate plugin load filter, it works fine. * Steps to reproduce: 1. install Plugin “TablePress” by Author Tobias Bäthge 2. install Plugin “plugin load filter” 3. In admin menu click on “TablePress” 4. Create a new table 5. Right Click on a table cell and choose “Insert Image” or click on the “Insert Image” button below the table. 6. The image does not get inserted throwing an PHP Error * ```wp-block-code PHP Fatal error: Uncaught TypeError: urlencode(): Argument #1 ($string) must be of type string, array given ``` * The problem is triggered in mu-plugins/plf-filter.php on line 1002 * ```wp-block-code $GLOBALS['wp']->query_posts(); ``` * which calls wp_basename() with $path as an argument which contains an array at this point, which is not right. It should be a string and not an array. It then calls urlencode() which throws the error. * If you print out the $_POST variable for the ajax request it contains something like that: * ```wp-block-code Array ( [nonce] => f8a54e0db5 [attachment] => Array ( [id] => 769070 [post_content] => [post_excerpt] => [align] => right [image-size] => full ) [html] => [post_id] => 0 [action] => send-attachment-to-editor ) ``` * Since i cant hook into your plugin because it loads first as a mu-plugin I can ´t change this behavior. * My current workaround is: * ```wp-block-code if ($_POST['action'] === 'send-attachment-to-editor') { return false; } ``` * somewhere above line 1002 in mu-plugins/plf-filter.php * Thank you very much for your help.

Does ver4.0.12 still cause an error? * Can you reproduce this by enabling only the Plugin load filter and TablePress plugins and disabling all other plugins? * It says that the urlencode() function is causing the error, but the plugin load filter plugin does not use the urlencode function directly.　It seems that the urlencode() function is used in several places in the TablePress plugin, so I think that it is necessary to deal with it as a fundamental problem * Thread Starter [reasonx](https://wordpress.org/support/users/reasonx/) * (@reasonx) * [3 years, 5 months ago](https://wordpress.org/support/topic/problems-with-plugin-tablepress/#post-16335319) * Hi, * thank you very much for your answer. I was already using version 4.0.12 of PLF. And the error also occours when switching off all plugins except tablepress & PLF. * After your answer I testet it again and I found out, that the error only occurs when using PHP 8.1. If I switch my local environment back to PHP 7.4 it works fine. That is because in PHP 7.4 PHP only throws a warning whereas in PHP 8.1 PHP throws a fatal error. Did you also test with PHP 8.1? If not, you could try again to reproduce the error. You have to create a table and then insert an image to a table cell. The Ajax call should return an PHP Error when running PHP 8.1. * In the meantime tablepress got updated to version 2.0.2 so I installed that update. Unfortunately the problem still exists. * Maybe the stacktrace is helping: * ```wp-block-code [error] FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught TypeError: urlencode(): Argument #1 ($string) must be of type string, array given in /wp-includes/formatting.php:5525 Stack trace: #0 /wp-includes/formatting.php(5525): urlencode() #1 /wp-includes/class-wp-query.php(2134): wp_basename() #2 /wp-includes/class-wp-query.php(3749): WP_Query->get_posts() #3 /wp-includes/class-wp.php(663): WP_Query->query() #4 /wp-content/mu-plugins/plf-filter.php(1020): WP->query_posts() #5 /wp-content/mu-plugins/plf-filter.php(298): Plf_filter::plf_filter() #6 /wp-includes/class-wp-hook.php(310): Plf_filter::active_plugins() #7 /wp-includes/plugin.php(205): WP_Hook->apply_filters() #8 /wp-includes/option" while reading response header from upstream, request: "POST /wp-admin/admin-ajax.php HTTP/1.1", referrer: "/wp-admin/admin.php?page=tablepress&action=edit&table_id=609" ``` * As I said my current workaround for this is to put this code * ```wp-block-code if (!empty($_POST['action']) && $_POST['action'] === 'send-attachment-to-editor') { return false; } ``` * into /mu-plugins/plf-filter.php before $GLOBALS[‘wp’]->query_posts(); * Thank you very much for your help. * Plugin Author [enomoto celtislab](https://wordpress.org/support/users/enomoto-celtislab/) * (@enomoto-celtislab) * [3 years, 5 months ago](https://wordpress.org/support/topic/problems-with-plugin-tablepress/#post-16343755) * In my environment (PHP8.1.13).
