Delete multiple records<\/b> on a single click is very useful for the large data list. This feature provides a user-friendly way to remove multiple records from the database quickly. The user doesn’t need to click multiple times for delete multiple rows, instead of that, all records can be deleted on a single click.<\/p>\n
Multiple records deletion functionality can be easily implemented using checkboxes. You can use the checkbox to select each record in the data list and delete all the selected records from the database. Also, the Select \/ Deselect all checkboxes<\/b> feature will make it easy to select multiple records because it allows the user to check or uncheck all rows at once. In this tutorial, we will show you how to delete multiple records from database using checkbox<\/b> in CodeIgniter.<\/p>\n
The example code, the following steps will be followed to delete multiple records from database in CodeIgniter<\/b>.<\/p>\n To store the user’s data a table needs to be created in the database. The following SQL creates a The Users controller contains 2 functions, index()<\/b> –<\/p>\n The User model handles the database related works.<\/p>\n\n
