php - Undefined variable not allowing me to insert file into database table column -
i'm uploading audio files directory , storing file name info in database. have done successfully.
next wanted create default image each audio file, use php add audio files title image , tack on unique id file name. have done successfully. learned following tutorial.
example image:
the problem i'm having getting audio files image insert database column on upload. here database image. need file name of newly created audio image go rt_file column. can echo out later.
i hoping on i'm going wrong.
the current error is: undefined variable: rt_file. don't understand why...? not define have defined above insert statement this:
$rt_file = preg_replace('/\s+/', '-', "../ringtones/rtimage/".($ringtone_image[0]['ring_name'])."-".substr(md5(microtime()),rand(0,26),5).".jpg"); i hate post code know it's frowned upon, apologize in advance, i'm not sure problem lies.
if has time through great, if not totally understand.
here code:
<?php include_once($_server['document_root'] .
