PDOCrud allows the editing of related records of different table i.e. similar to nested table. Nested Table is a table inside a table. It is not stored in that way but similar concept is used. You can define relation between the two tables data using some binding column value.
//student table object
$pStudent = new PDOCrud();
$pStudent->multiTableRelationDisplay("tab", "Student");
//student's class object
$pStudentClass = new PDOCrud(true);
$pStudentClass->crudTableCol(array("class_id", "class_name", "code"));
$pStudentClass->dbTable("class");
//first paramater is first table(object) columnn name and 2nd parameter is 2nd object column name
$pStudent->multiTableRelation("class_id", "class_id", $pStudentClass);
$pStudentClass->multiTableRelationDisplay("tab", "Class");
//student's class object - adding one more table
$pStudentTransport = new PDOCrud(true);
$pStudentTransport->dbTable("vehicle");
//first paramater is first table(object) columnn name and 2nd parameter is 2nd object column name
$pStudent->multiTableRelation("transport_id", "vehicle_id", $pStudentTransport);
$pStudentTransport->multiTableRelationDisplay("tab", "Vehicle");
//2nd level of nesting - relating section to class(first student to class and then class to section)
$pStudentSection = new PDOCrud(true);
$pStudentSection->dbTable("section");
//first paramater is first table(object) columnn name and 2nd parameter is 2nd object column name
$pStudentClass->multiTableRelation("class_id", "class_id", $pStudentSection);
$pStudentSection->multiTableRelationDisplay("tab", "Section");
$pStudent->crudTableCol(array("student_id","first_name","last_name"));//optional
echo $pStudent->dbTable("student")->render();
