->fetch()

->fetch() – fetch next row

Synopsis

boolean $DB_DataObject->fetch ( )

Description

The fetch method gets the next row and sets the objects variables to the rows data. It returns TRUE if data has been collected, and FALSE when there is no more data.

Return value

boolean - TRUE on success and FALSE on failure.

Note

This function can not be called statically.

Fetch is called by staticGet and get calls, so you can override this method in your classes, to add extra data to your object (like formated dates etc)

Example

Simple find and fetch of data based on object Vars

<?php
$person 
= new DataObjects_Person;

$person->hair 'red';
$person->has_glasses 1;

$number_of_rows $person->find();

$people = array();
while (
$person->fetch()) {
    
/* store the results in an array */
    
$people[] = clone($person);
    echo 
"GOT {$person->name}<BR>";
}
?>

Overriding fetch to add extra data.

<?php
function fetch() {

  
$ret parent::fetch();
  if (
$ret === false) {
      return 
false;
  }
  
$this->dateFormated date('d/M/Y'$this->date);
  return 
true;
}
?>
