Another issue is the user deletion, when I delete FOP user, it did not delete user from the fop2uttons.
So, I have edit the functions.inc.php again to look for the function statement fop2_del_user($id),
and I added a new line to delete the user from fop2buttons using the exten field.
Cheers!

function fop2_del_user($id) {
$id = intval($id);
$thisItem = fop2_get_user($id);
$exten = $thisItem['exten'];
$results = sql("DELETE FROM fop2UserGroup WHERE exten = '$exten'","query");
$results = sql("DELETE FROM fop2users WHERE id = '$id'","query");
$results = sql("DELETE FROM fop2buttons WHERE exten = '$exten'","query");[/color:3pgvj4ls]

I have finally fixed my problem by editing the PHP script in /var/www/html/admin/modules/fop2admin.
In the PHP file functions.inc.php, I comment the following statement, then ev erything is working fine for now.
Cheers!

       // fop2_del_button($boton_id_a_borrar);

<?php

function fop2admin_get_config($engine) {
// Executed on APPLY in FreePBX, we regenerate the fop2buttons if needed
global $amp_conf, $db, $active_modules;

$fopbutton        = fop2_all_freepbx_buttons();
$botonesdefinidos = fop2_list_botones();

foreach ($botonesdefinidos as $devname => $datarray) {
   if(!array_key_exists($devname,$fopbutton)) {
       $results = sql("SELECT id FROM fop2buttons WHERE device='$devname'","getRow",DB_FETCHMODE_ASSOC);
       $boton_id_a_borrar  = $results['id'];
       // fop2_del_button($boton_id_a_borrar);[/color:14yvsbpm]
   }
}

That is the "Apply Configure change" red button on top screwed up the whole thing!!! (I am running on FreePBX 2.2.1)

When I select fop2admin from Module Admin and click on "process", and then click on "confirm" button to complete the installation, I immediately login into mysql and look into table fop2buttons and I can see all the extensions are there. However, when I click on the red button "Apply configuration changes" on top, and I try view the table again, all extension are gone except the last 3 records??? how come like that?

I have run /usr/local/fop2/autoconfig_buttons_freepbx.sh both with and without fop2admin.

When the fop2admin plugin installed, I can't see any extensions except ZAP/G0 and ZAP/G1.

When the fop2admin plugin uninstalled, I can see all the extension buttons.

I looked into the shell script /usr/local/fop2/autoconfigure_buttons_freepbx.sh and I realized that the script
actually retrieve the extension buttons from the table fop2buttons when it found there is fop2admin plugin as shown below:-

mysql -ENB -u $DBUSER -p$DBPASS -h $DBHOST $DBNAME -e
"SELECT device AS channel,type,if(type<>'trunk',exten,'') AS extension,
label,mailbox,context,'$QUEUECONTEXT' as queuecontext,concat('',mailbox) AS extenvoicemail,
privacy,`group`,IF(type='trunk',IF(email<>'',concat('splitme-',email),''),email) as email,
queuechannel,originatechannel FROM fop2buttons WHERE device NOT LIKE 'USER/%' AND device<>''
ORDER BY type,exten" | sed '/**/d' | sed 's/: /=/g' | sed '/.=$/d' | while read LINEA

So, I open and view the data in the table fop2buttons, and I noticed that there only 3 records which are the
ZAP/G0, ZAP/G1 and Park/default? Where are the extensions? I can only found them in table fop2users???

Can anyone please advise me what is gone here?

Thankyou and best regards,
Chu

/usr/local/fop2/autoconfig-buttons-freepbx.sh

And look at the output.

Did you make some changes to fop2.cfg ? Did you install the fop2admin module ?
