objects within objects???

[Anon]

Hi All!

Okay, I posted this one a while back but it's still giving me a headache!

Below is a class I've set up to hold a news item:

class NewsStory
{
var $NewsID;
var $Author;
var $Headline;
var $TimeStamp;
var $NewsText;

function NewsStory($NewsID = "", $newHeadline = "", $newNewsText = "", $newAuthor = "", $newTimestamp = "")
{
    $this->Author = $newAuthor;
    $this->Headline = $newHeadline;
    $this->Timestamp = $newTimestamp;
    $this->NewsText = $newNewsText;
}

}

Then I've got another class that, along with other info and proper member functions, holds an array of these beasties:

class News
{
var $Stories;
var $StoryCount;

function News()
{
    $this->Stories = array();
    $this->StoryCount = 0;
}

function LoadFromFile($Filename)
{
    if(!file_exists($Filename))
    {
        return false;
    }

    if (!$file = fopen($Filename, "rb"))
    {
        return false;
    }

    $this = unserialize(fread($file, 1000));
    fclose($file);

    for ($count=0; $count < $this->StoryCount; $count++)
    {
        $this->Stories[$count]->NewsText = stripcslashes($this->Stories[$count]->NewsText);
        $this->Stories[$count]->Headline = stripcslashes($this->Stories[$count]->Headline);
    }

    return true;
}

function AddStory($newHeadline, $newNewsText, $newAuthor, $newTimestamp)
{
    $newNewsText = ereg_replace("\n", "<br>", $newNewsText);
    $this->Stories[] = new NewsStory($this->StoryCount, $newHeadline, $newNewsText, $newAuthor, $newTimestamp);
    $this->StoryCount++;

    return true;
}

...lots of other member functions here...

}

Okay, all it fine on my Win32 system running Apache and PHP4 but when I u/l the script to my server (Linux running PHP3) I get all sorts of parse errors.

I slowly went through the code commenting out the lines that gave me errors and I noticed a trend. All the erronous lines were similar to the following:

$this->Stories[$count]->NewsText = stripcslashes($this->Stories[$count]->NewsText);

By all like this I mean that they were all lines that took an element of the Stories array and referenced an attribute within that news object instance.

So here's my question. Can I do this in PHP3? If not is there a way of getting around it? Please help...my site is without a proper news engine at the moment!

Thanks greatly in advance!

Steve,

If you look at the PHP manual, it says 

stripcslashes

(PHP4 >= 4.0b4)

...

Note: Added in PHP4b3-dev.

So, I believe it will not work under PHP3 (the one installed under your hosting server).

What I recommend is that you create your own function named stripcslashes. I do not know what it REALLY does (the manual is kinda vague). So maybe I can helpp if you can tell me what the function needs to strip off the string.

hope this helps,

Hiya!

Thanks for your quick reply. Unfortunately I fear that this isn't the real problem! If I comment these lines out then I still get parse errors on other lines. This is a member function of the News class:

function UpdateStory($Item, $newHeadline, $newNewsText, $newAuthor, $newTimestamp)
{
    if (!isset($this->Stories[$Item]))
    {
        return false;
    }

    $newNewsText = ereg_replace("\n", "<br>", $newNewsText);

    >> $this->Stories[$Item]->Headline = $newHeadline;
    >> $this->Stories[$Item]->NewsText = $newNewsText;
    >> $this->Stories[$Item]->Author = $newAuthor;
    >> $this->Stories[$Item]->Timestamp = $newTimestamp;

    return true;
}

The lines marked with >> give me parse errors also. Is there something else wrong with my code???

hmm, its very odd. I tried nested classes under my PHP4 and it works fine. I don't have php 3 so I can't test it there.

how did you initialize the Stories array inside the class?

also, can you give me the version number of your PHP3 processor in your server?

$this->Stories[$Item]->Headline = $newHeadline;
$this->Stories[$Item]->NewsText = $newNewsText;
$this->Stories[$Item]->Author = $newAuthor;
$this->Stories[$Item]->Timestamp = $newTimestamp;

---

try this

function workAround($obj, $headline)
{
$obj->Headline = $headline;
return($obj);
}

$this->Stories[$Item] = workAround($this->Stories[$Item], $newHeadline)

hope it works
