What is the code that creates those rows and what is the code you are using to insert?

Just take a look at the table via PhpMyAdmin. Hopefully you have that available. * Thread Starter [mic3000](https://wordpress.org/support/users/mic3000/) * (@mic3000) * [14 years, 12 months ago](https://wordpress.org/support/topic/add-custom-field-dynamically-1/#post-2143677) * OK.

The first step is getting things to insert into the db correctly. * I know you are going to want to display the data in your metabox somewhere but its going to be hard to find and debug the problem if you don’t know what, if anything, is even in the DB. If you don’t know what is being inserted, when you try to display the data and have a problem, you won’t know if the problem is with the insert or with the display code. Therefore, watch the DB using some other tool like PhpMyAdmin so that you know what is going on there. * Thread Starter [mic3000](https://wordpress.org/support/users/mic3000/) * (@mic3000) * [14 years, 12 months ago](https://wordpress.org/support/topic/add-custom-field-dynamically-1/#post-2143680) * well, i see db, wordpress put data into db correctly, but only the first values. * If i try to add another values, wordpress save only the first line, then only the first student. * [s_ha_dum](https://wordpress.org/support/users/apljdi/) * (@apljdi) * [14 years, 12 months ago](https://wordpress.org/support/topic/add-custom-field-dynamically-1/#post-2143681) * Did you make the change I suggested? * Put `print_r($this->meta_box_students_fields);` on the line right before `foreach( $this->meta_box_students_fields...` and post that for me. * Thread Starter [mic3000](https://wordpress.org/support/users/mic3000/) * (@mic3000) * [14 years, 12 months ago](https://wordpress.org/support/topic/add-custom-field-dynamically-1/#post-2143683) * if i put this on the line right before foreach ($this->meta_box_students_fields… i dont see nothing! * [s_ha_dum](https://wordpress.org/support/users/apljdi/) * (@apljdi) * [14 years, 12 months ago](https://wordpress.org/support/topic/add-custom-field-dynamically-1/#post-2143684) * Try `var_dump($this->meta_box_students_fields);` instead.
