Inheritence Problem.. (i think?)

[trevorkavanaugh]

Hello,

 

I am new to PHP and was writing these classes to convert HTML elements into objects. Everything seems to have gone good until attempting to send the attributes to a variable parameter function, which after testing all values were passed correctly and even are valid when testing the attribute name given with the corresponding property name. These are passed as: $object->attributes("attribute1=value1","attribute2=value2"). Once the arguments have reached the parent class, they are then checked to see if the attribute value given matches any of the objects property names. If so, the value is set for the property.

 

Basically, only the type="checkbox" is being set. I set some echo's to display what my problem is

 

 

Thanks for your time

Hehe, silly me just took a shower and realized I had type set to "checkbox" in the child element. Took that off and it appears none of the real properties are being set. I think its on line 93: $$property = $val;

 

All help still greatly appreciated

[trevorkavanaugh]

Just solved it

 

had to change line 93:

 

$$property = $val;

 

to:

 

$this->{$property} = $val;
