I'm using php. I'd like to know how can I dynamically export data to excel file (.xls). in the query below in entered the fields in the clause Select which i want to see in the excel file.
$query = "SELECT f.attendee_id as id1, f.answer as Prenom, l.answer as Nom, c1.answer as choix
FROM wp_events_answer f
JOIN wp_events_answer l ON f.attendee_id = l.attendee_id
JOIN wp_events_answer c1 ON f.attendee_id = c1.attendee_id
WHERE (f.question_id = 1) AND (l.question_id = 2) AND (c1.question_id = 28);";
And i also entered the labels of this fields:
$tbl= " <table border='1'>
<tr height='50px'><td WIDTH='50px' align='center'>ID</td><td WIDTH='50px' align='center'>Prenom</td><td WIDTH='50px'align='center'>Nom</td><td WIDTH='50px' align='center'>Choix 1</td><td WIDTH='50px' align='center'>Choix 2</td></tr>";.;
But i'd like that all this became dynamic because the user can create and modify the forms. So if the user add or modify a field the export will only works if this field is also modified in the code (Select clause).
Can you explain me how can I do this?
Thanks
MYSQL code:
SELECT f.attendee_id as id1, f.answer as Prenom, l.answer as Nom, c1.answer as choix
INTO OUTFILE '/path/to/file.csv'
FIELDS
TERMINATED BY ';'
OPTIONALLY ENCLOSED BY '"'
FROM wp_events_answer f
JOIN wp_events_answer l ON f.attendee_id = l.attendee_id
JOIN wp_events_answer c1 ON f.attendee_id = c1.attendee_id
WHERE (f.question_id = 1) AND (l.question_id = 2) AND (c1.question_id = 28);
只需将您的数据以CSV(逗号分隔)格式写入响应缓冲区或磁盘文件(以后您可能会允许用户下载或强制下载)。
