Attempt to assign property of non-object in...


Posted on 16th Feb 2014 07:03 pm by admin

I'm having issues with the following function in PHP 5...

function getTreeWithChildren()
{

$category_id = $this->fields['id'];
$parent_id = $this->fields['parent'];

$this->DB->build( array( 'select' => join(',', $this->getFields()),
'from' => $this->table,
'order' => $this->fields['sort']
) );
$this->DB->execute();


// create a pseudo root level object
$root = new stdClass;
$root->$category_id = 0;
$root->children = array();

$arr = array($root);

// populate array and create empty child array
while ($row = $this->DB->fetch()) {
$arr[$row->$category_id] = $row;
$arr[$row->$category_id]->children = array();
}

// build child data
foreach ($arr as $id => $row) {
if (isset($row->$parent_id))
$arr[$row->$parent_id]->children[$id] = $id;
}

return $arr;
}



I'm getting the error

QuoteAttempt to assign property of non-object in ... on line 391

which is...

$arr[$row->$category_id]->children = array();

I've tried typecasting "$this->DB->fetch()" to an object with...

while ($row = (object) $this->DB->fetch()) {

but get a maximum execution time exceeded error instead.

The code was originally written for PHP 4 so I suspect it might be a way the objects are handled and the use of stdClass()?

I'd be extremely grateful if somebody could give me pointers to make this PHP5 compatible (5.2.9)? Thanks in advance
