Title: AbanteCart core v.1.2.6 Cannot modify header information-headers already sent
Post by: yonghan on March 21, 2016, 07:20:22 AM

Hi admins,

I'm trying to use the upgrade my extension and I use both upgrade.sql and upgrade.php. I got this warning

2016-03-21 11:27:29 - warning:  AbanteCart core v.1.2.6 Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\testing\t126\extensions\xxx\upgrade.sql:36) in <b>C:\xampp\htdocs\testing\t126\core\engine\controller.php</b> on line <b>214</b>

I attach the upgrade process screenshot here. Did I missed something in the process? And is it possible to create a new table via upgrade.php? I tried that before but the table aren't created.Thanks

please check is output buffering enabled on your testcase. See http://php.net/manual/en/outcontrol.configuration.php for details

I want to make an upgrade routine for my extension that involves sql queries and some php routines. This is what i have in my extension config file:

Code: [Select]

<upgrade>
        <sql>upgrade.sql</sql>
<trigger>upgrade.php</trigger>
    </upgrade>

i guess you have a sql error.
Please check your compounded sql in sql editor like a Mysql Workbench (or phpMyAdmin)
