Hello again, I have the following code that is returning the correct value for '$table_name':
| Code: | $obj = mysqli_fetch_object($result);
$table_name = $obj->items_table;
|
However, what I would like to do is this:
| Code: | define('PRODUCT_ITEMS_TABLE_HEADER', 'items_table');
.
.
$obj = mysqli_fetch_object($result);
$table_name = $obj->PRODUCT_ITEMS_TABLE_HEADER;
|
This leaves no value in $table_name. Is there a way to use a definition after '$obj->' ?
Thanks! |

I was able to solve the problem using this code:
| Code: |
define('PRODUCT_ITEMS_TABLE_HEADER', 'items_table');
.
.
$row = $result->fetch_assoc();
$table_name = $row[PRODUCT_ITEMS_TABLE_HEADER];
|
Then realized that not being able to use $obj->SOME_DEFINITION, is probably not specific to mysqli, but a general PHP error, and tried this simpler example:
| Code: | <?php
define('CLASS_PROPERTY', 'model');
class mini{
private $model;
public function __construct() {
$this->model = "cooper";
echo $this->CLASS_PROPERTY;
$error = error_get_last();
echo $error[message];
}
}
$car = new mini();
?> |
Output:
| Code: | | Undefined property: mini::$CLASS_PROPERTY |
In this context, PHP will not resolve the definition? |

Hi again. 
To use a dynamic property, you can just add braces:
$obj->{SOME_DEFINITION} |

Hello, and thank you again! I spent hours on it, when it didn't even matter anymore. Best I came up with was an ugly looking the exec() function.
I would like to say, that's it. Now I can finish my project without any more questions  . |
