Re: [PHP] Updating inherited attributes without __construct()
Sorry, I probably should have included the add()
function from the parent. As well as all of the parent
constructor.
Basically the object takes an array of key=>value pairs
and parses them into a string for output. When it
takes in the array of pairs it needs to check the keys
against a list of valid keys. I have no preference on
how to store the list of valid keys other than to add
more a constructor doesn't need to be called.
class parent{
$validkeys = 'name,size';
$attributes = array();
__construct($set){
foreach($set as $key=>$value){
if(isValidKey($key)){
$this->attributes[$key] = $value;
}
}
}
__toString(){
$output = "";
foreach($this->attributes as $key=>value){
$output .= sprintf(TEMPLATE, $key, $value);
}
}
__set($key, $value){
if(isValidKey($key)){
$this->attributes[$key] = $value;
}
}
isValidKey($key){
...Something goes here...
}
}
class child extends parent{
...All this needs to do is tack on values 'color,shape'
to parent's valid keys...
}
class grandchild extends child{
...All this needs to do is tack on values
'cost,location' to child's valid keys...
}
Most sub classes won't need anything different from
their parent but the expanded list of valid keys.

i dont quite understand this reasoning.. if you want to add some valid keys,
based upon the design of the parent, it seems to me the children do have a
need for an overridden constructor. if you have accessor methods w/ a
consistent naming convention, you could omit the $validKeys array
altogether, and determine if a given field is valid based upon runtime
introspection. something like this,
/// in the parent class
protected function isFieldValid($field) {
if(method_exists($this, 'get' . ucfirst($field)))
return true;
else
return false;
}
this will work in all the child classes as well, as long as you stick to a
consistent naming convention, and you can of course add a check for a set..
method as well if you like. im not saying this technique is the holy grail
or anything, im merely offering it as an alternative to your current
solution.

[PHP] Updating inherited attributes without __construct()
I have a class that has a list of valid keys, and an
array of values. When a value is added to the array
it's key is first checked against the list of valid
keys (this is to prevent injection issues we have been
having later on in the project).
class parent{
private $validkeys = 'title,color,name';
private $values = array();
}
That class is inherited by other classes that mostly
just have an expanded list of valid keys. I would like
to be able to update the valid key list without having
to craft a constructor for child objects. I would
rather not give each child class the constructor,
__construct()
{
$this->validkeys.= ',setting,...';
parent::__construct();
}
since most child classes have no need of a unique
constructor.
I thought of defining a protected extended valid keys
variable in the parent that the child could set that
the parent constructor would combine with the valid keys.
class parent{
private $validkeys = 'title,color,name';
private $values = array();
protected $extendedkeys;
__construct(){
$this->validkeys .= $this->extendedkeys;
}
}
But the children may become parents for further child
classes. And if the sub-child classes use the
$extendedkeys variable it will overwrite the
intermediate class's version.
Is there any way to tack on extra additional data by
the child classes without creating a constructor. I am
not wedded to strings as a means, it just needs to be
able to hold a string value.
Thanks

[PHP] Problems with includes
I am trying to keep my tools and pages segregated for a variety of reasons (organization, security, etc). And I am having problems with my includes on my LAMP box. My user facing tools are not including my utility classes and files. The root directory of my web server (www.hostname.com/) is: /srv/www/html/ My utility classes and files that need to be included by many of my user tools are in subdirectories of: /srv/www/html/Tools ie /srv/www/html/Tools/tool1/tool1.php /srv/www/html/Tools/tool2/tool2.php included in these sub directories are tool testing pages (toolname-test.php) and other includes. As long as the file that is including other files is in the same directory as the files it is including, it works just fine. My user tools each have their own subdirectories off the webserver root /srv/www/html/ ie /srv/www/html/library/index.php So I would think that to include my utility files into my user tools I would start the file with something like this: require "/Tools/tool1/tool1.php"; require "/Tools/tool2/tool2.php"; But when I do I get: require(/Tools/dbtools/dbtool.php) [function.require]: failed to open stream: No such file or directory /srv/www/html/lib/index.php, line 16 require() [function.require]: Failed opening required '/Tools/dbtools/dbtool.php' (include_path='.:/usr/share/pear') /srv/www/html/lib/index.php, line 16 Am I missing something? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Variable Scope from child to parent
I am trying to get a child class to pass an array of valid keys to it's
parent when the constructor is run, and the parent appends the data to
one of it's array of valid keys. Then it walks through an array pulling
out values that have valid keys, and putting them in an array for
processing later. I have tried explicitly stating the variable scope.
abstract class parentclass
{
protected $vkeys= array('title1','title2','title3');
protected $a;
function __construct($set = NULL, $special = NULL)
{
self::$this->vkeys= array_merge(self::$this->vkeys, $special);
foreach($set as $key=>$value)
{
if (in_array($key,self::$this->vkeys))
{
$this->a[$key] = $value;
}
}
print_r(self::$this->vkeys); //output below
print_r(self::$this->a); //output below
}
}
class childclass extends parentclass
{
protected $vkeys= array('titleA', 'titleB', 'TitleC');
function __construct($set, $special = NULL)
{
parent::__construct($set, self::$this->vkeys);
unset(self::$this->vkeys);
}
}
Unfortunately it seems to duplicate the child's array instead of
appending. Explicitly stating scope does not seem to help.
print_r(self::$this->vkeys);
Array (
[0] => titleA
[1] => titleB
[2] => titleB
[3] => titleA
[4] => titleB
[5] => titleB
)
print_r(self::$this->a);
Array()
Any thoughts?

[PHP] Tracking down the elusive "expecting T_PAAMAYIM_NEKUDOTAYIM"
I have a class that is throwing the error:
syntax error, unexpected ')', expecting T_PAAMAYIM_NEKUDOTAYIM ...
It is appearing in the constructor of a parent class
abstract class parent
{
protected $titles = array('title1','title2','title3');
protected $a;
function __construct($set = NULL, $special = NULL)
{
self::$this->titles = array_merge(self::$this->titles, $special);
//error
foreach($set as $key=>value)
{
if (array_key_exists($key,$this->titles)
{
$this->a[$key] = $value;
}
}
}
}
class child extends parent
{
protected $titles = array('titleA', 'titleB', 'titleC');
function __construct($set, $special = NULL)
{
self::$this->titles = array_merge(self::$this->titles, $special);
parent::__construct($set, self::$this->titles);
unset($this->titles);
}
}
Basically parent is an extensible tool for holding data with titles that
dictate behavior later in the script. Eventually I will have a dozen or
so different child classes each using an identical API. But first I
need this constructor to work. The parent constructor just tacks the
array of titles from the $special attributes onto the end of the $titles
array.
