This form may be used to insert multiple set of data. Multiple set of records can be inserted at a single click in the “Submit” button. This is highly efficient in the case of bulk data entry. Here is a set of jQuery and PHP code which will perform as per the requirement.
To implement the code you have to activate jQuery first. Then you have to include the “lzmultiform” jQuery plugin (two files the .js and .css) and initialize it on document load for the form you want to activated it for. This plugin will create an interface on top of the form, by which user will be able to increase the number of field sets.
