* This should be moved to another class : DB_DataObject_Validate
2008-09-30 14:38:47 +01:00
* FEEL FREE TO SEND ME YOUR VERSION FOR CONSIDERATION !!!
*
* Usage :
* if ( is_array ( $ret = $obj -> validate ())) { ... there are problems with the data ... }
*
* Logic :
* - defaults to only testing strings / numbers if numbers or strings are the correct type and null values are correct
* - validate Column methods : " validate { ROWNAME}() " are called if they are defined .
2019-04-16 00:20:20 +01:00
* These methods should return
2008-09-30 14:38:47 +01:00
* true = everything ok
* false | object = something is wrong !
2019-04-16 00:20:20 +01:00
*
2008-09-30 14:38:47 +01:00
* - This method loads and uses the PEAR Validate Class .
