I'm examining some auto-generated code in the Base class of one of my
model classes. I'm curious about the line with the $this-
>alreadyInSave. It is first set to true, and then later it is set to
false. As near as I can see, it is always set to true, and then false.
What is the point of this? If PHP was asynchronous, this would make
more sense, but PHP is procedural. Does this boolean flag exist for
dealing with Ajax requests?
protected function doSave($con)
{
$affectedRows = 0;
if (!$this->alreadyInSave) {
$this->alreadyInSave = true;
if ($this->isModified()) {
if ($this->isNew()) {
$pk = NewNewsPeer::doInsert($this,
$con);
$affectedRows += 1;
$this->setId($pk);
$this->setNew(false);
} else {
$affectedRows +=
NewNewsPeer::doUpdate($this, $con);
}
$this->resetModified();
}
$this->alreadyInSave = false;
}
return $affectedRows;
}
