Many to Many Join Query in CodeIgniter -

-

All previous attempts at JOIN have left me with disk or item data, which is the result of the ID, the result of the title key (

  item table field: id, headline disk table field: id, title item_date table field: item_id, disc_id  
 / code>  
 How do I create a double join so that I can use a disc related to an item. Currently I will send two different questions For a single item record, then for a single disk array.  
 In addition to being included in a query, if I ever want to get more than 1 record , I currently have to run 2 queries per item because I can not be included in my data.  
 Please help !! I think this is my last many many obstacles (though speaking very soon Dare not ).   
 
 
 Because both items and discs have column names and titles, they will overwrite each other         title as item_title, d.title as item i, disc d, item_disc as i.id = Order by m.item_id and d.id = m.disc_id i.title, d.title

for an item and its disk: 

  M. *, I.title item items, as d.title item i, disc d, item_disc m from discrete. Id = m.item_id =? And replace d.title

by the d.id = m.disc_id command? Items you want with

Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
