->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;
}
?>
