tabledb

Generic class that allows managing a database table. Creates a page to perform basic operations with a table.

// METHODS // __construct() - Class Constructor // ativaCampos($ value, $ action) - Makes visible the fields to be displayed by passing the value = 1 (or not passing a value) and hides it by passing the value = 0. When value // passed is 1 the field is active (visible) and when the field is 0 the field is disabled. Action defines the behavior of seeing, new, // editing. // consultaSQL($ sql) - given a sql it returns a list of data. // determinaChave() - Analyzes the structure of the database table and determines which is the key // devolveValorDaLista($ field, $ key) - Find the value of a field for a given key where the field is the name of the field to be consulted the list of values and key is the id // of the value to be searched. // encriptar($ text, $ cipher = "md5") - encrypts a text according to a past method where text is the text to be encoded and encryption is the type of cipher used // fazHTML() - Do what is necessary to maintain the table in an html page. Lists the data and allows you to insert new ones, edit and delete records. Use a 'do' parameter to // make decisions // fazLista() - Makes an HTML table with the list of all records in the table.

Those with value will be read. // getDo() - read the 'do' parameter of the HTML form // getTextos($ key) - returns a pre-entered text where key is the name of the field we want to get the value // includes() - Set of includes necessary for the format of the list of records in the table // inputHTML($ field, $ value) - returns the appropriate html to construct a field of the type passed in the Type attribute. field is an array with the information of a // field, includes: label, Field, Type and etc and value is the default value to be included in the field // preparaSQLGeral() - Prepare a string with the table's SQL statement (of type SELECT * FROM Table).
