PHP Warning: array_merge(): Argument #1 is not an array

Post by doiggl »

# perl add_device.php --description="BiPAC 7401VGPR3" --ip=192.168.1.254 --template=1 --version=2 --community="public"
PHP Notice: Undefined variable: plugins in /usr/share/cacti/include/plugins.php on line 31
PHP Warning: array_merge(): Argument #1 is not an array in /usr/share/cacti/include/plugins.php on line 31
Adding BiPAC 7401VGPR3 (192.168.1.254) as "Generic SNMP-enabled Host" using SNMP v2 with community "public"
Success - new device-id: (4)

Looks like its its complaining about this section of code. Any ideas on how to fix. Thanks Glenn ?
Software installed - cacti-0.8.7g and cacti-plugin-0.8.7g-PA-v2.8 and autom8-v0.35.

$oldplugins = read_config_option('oldplugins');
$oldplugins = explode(',', $oldplugins);
$plugins = array_merge($plugins, $oldplugins);

If possible, use PIA 2.9
To cure the error, please change function to look like

Code: Select all

/**
 * This function executes a hook.
 * @param string $name Name of hook to fire
 * @return mixed $data
 */
if (!is_array($plugins)) {
	$plugins = array();
}

$oldplugins = read_config_option('oldplugins');
if (strlen(trim($oldplugins))) {
	$oldplugins = explode(',', $oldplugins);
	$plugins    = array_merge($plugins, $oldplugins);
}

Hello,
I still continue to have issues even after changing the fuctions. My include/plugin.php looks as follows
<?php

/*
* Copyright (c) 1999-2005 The SquirrelMail Project Team (http://squirrelmail.org)
* Licensed under the GNU GPL. For full terms see the file COPYING.
*/


global $plugin_hooks, $plugins_system;
$plugin_hooks = array();
$plugins_system = array('settings', 'boost', 'dsstats');

function use_plugin ($name) {
global $config;
if (file_exists($config['base_path'] . "/plugins/$name/setup.php")) {
include_once($config['base_path'] . "/plugins/$name/setup.php");
$function = "plugin_init_$name";
if (function_exists($function)) {
$function();
}
}
}

/**
* This function executes a hook.
* @param string $name Name of hook to fire
* @return mixed $data
*/

if (!is_array($plugins)) {
$plugins = array();
}

$oldplugins = read_config_option('oldplugins');
if (strlen(trim($oldplugins))) {
$oldplugins = explode(',', $oldplugins);
$plugins = array_merge($plugins, $oldplugins);
}


/* On startup, register all plugins configured for use. */
if (isset($plugins) && is_array($plugins)) {
foreach ($plugins as $name) {
use_plugin($name);
}
}


And the error still remains.

Did you import pa.sql into cacti database?

Greetings,

Running in to the same problem even with the suggested changes to plugin.php. Did you ever get this resolved?

Thanks,
jmw

I suggest that you don't change base PIA files. The only file you need to change in Cacti 0.8.7h should be config.php.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?
