[Plugin: Contact Form 7 to Database Extension] No Data Submitted

It should be that simple…
Hard to say what the problem is. I suppose you didn’t see any error message when activating the CFDB plugin?

If it cannot create the table it needs to use in your database that would cause it to fail. In PHPMyAdmin check to see if the wp_cf7dbplugin_submits table exists.

You could try to see if there are error logs. You might have to set this up. You would create a file: wp-content/plugins/contact-form-7-to-database-extension/php.ini
In that file you would put something like:
error_log = /some-path/php-errors.log
then try a submission and see if the file contains anything.

Try manually creating the table:

CREATE TABLE IF NOT EXISTS wp_cf7dbplugin_submits
            submit_time DECIMAL(16,4) NOT NULL,
            form_name VARCHAR(127) CHARACTER SET utf8,
            field_name VARCHAR(127) CHARACTER SET utf8,
            field_value LONGTEXT CHARACTER SET utf8,
            field_order INTEGER,
            file LONGBLOB);

 ALTER TABLE wp_cf7dbplugin_submits ADD INDEX submit_time_idx ( submit_time);
 ALTER TABLE wp_cf7dbplugin_submits ADD INDEX form_name_idx ( form_name);
ALTER TABLE wp_cf7dbplugin_submits ADD INDEX field_name_idx ( field_name);

Try to sort out the error “‘gioitre.wp_cf7dbplugin_submits’ doesn’t exist”. Login with the same login WP uses, see if the table is there. See if you can “select * from wp_cf7dbplugin_submits”

Looks like I had a missing parenthesis. Try:

CREATE TABLE IF NOT EXISTS wp_cf7dbplugin_submits (
            submit_time DECIMAL(16,4) NOT NULL,
            form_name VARCHAR(127) CHARACTER SET utf8,
            field_name VARCHAR(127) CHARACTER SET utf8,
            field_value LONGTEXT CHARACTER SET utf8,
            field_order INTEGER,
            file LONGBLOB);

 ALTER TABLE wp_cf7dbplugin_submits ADD INDEX submit_time_idx ( submit_time);
 ALTER TABLE wp_cf7dbplugin_submits ADD INDEX form_name_idx ( form_name);
ALTER TABLE wp_cf7dbplugin_submits ADD INDEX field_name_idx ( field_name);
