phpMyVideoBlog & PHP 7

phpMyVideoBlog (MVB) is one of those commercial scripts that are heavily maintained one year and the next their development goes to a complete halt and although you buy the script, your only hope for support is their forum system, where the developer does reply from time to time.

According to their release notes, the latest plugin version 3.3 was released in November 2015 which is roughly a year back. As I was revising one site today, I noticed that the MVB plugin was prompting me to upgrade it and I went to the forum, downloaded the latest version then deactivated and removed the old plugin so that I could upload and install the new version, but when trying to activate it I was hit with the following error:

Fatal error: Uncaught Error: Call to undefined function mysql_get_server_info() in …/wp-content/plugins/myvideoblog/mvb_main.php

(The error is truncated to include only the most important info)

Just by looking at the error I realized that I was dealing with deprecated code given that the ‘mysql_‘ extension has been considered deprecated since PHP 5.5 and completely removed in PHP 7.

To fix this, I used a dirty trick that I sometimes employ when troubleshooting so i edited the /wp-content/plugins/myvideoblog/mvb_main.php file and commented out the following lines from within which were the only ones referencing the mysql_get_server_info() function:

if ( version_compare(mysql_get_server_info(), ‘4.1.0’, ‘>=’) ) {
if ( ! empty($wpdb->charset) )
$charset_collate = “DEFAULT CHARACTER SET $wpdb->charset”;
if ( ! empty($wpdb->collate) )
$charset_collate .= ” COLLATE $wpdb->collate”;

This fixes the issue and the plugin can be installed, but the script will no longer retrieve the MySQL version in order to execute the query to select the correct charset and collation string. This works on plugin upgrades, but may fail on new installations.

To fix this on new installations there are two possible workarounds:

  1. The script uses the version comparison only to insure that the MySQL version is higher or equal with 4.1.0 so if you’re running PHP 7 you’re clearly using higher PHP versions as this “check” was only justified with PHP 4 and earlier versions of PHP 5 so the version compare if statement can be removed altogether and only the following code can remain:
    if ( ! empty($wpdb->charset) )
    $charset_collate = “DEFAULT CHARACTER SET $wpdb->charset”;
    if ( ! empty($wpdb->collate) )
    $charset_collate .= ” COLLATE $wpdb->collate”;
  2. PHP 5.5 was the version that replaced the obsolete ‘mysql_‘ extension with ‘mysqli_‘ in order to make use of the better database driver available for PHP so mysql_get_server_info() will be changed to mysqli_get_server_info() as follows:
    if ( version_compare(mysqli_get_server_info(), ‘4.1.0’, ‘>=’) ) {
    if ( ! empty($wpdb->charset) )
    $charset_collate = “DEFAULT CHARACTER SET $wpdb->charset”;
    if ( ! empty($wpdb->collate) )
    $charset_collate .= ” COLLATE $wpdb->collate”;

Well that’s pretty much about it. If you’re still wondering what phpMyVideoBlog is here’s some insight from the developer’s site:
