Hello, Thanks for this, but I am not sure why everything was marked as selected. Gordon. On Wed, 2005-03-30 at 15:05 +0200, Carl McDade wrote:

The values on both sides of = = = have to be identical. There is no conversion by PHP as when using = =. $var = "123"; $var === 123; //false $var == 123; //true

Hello,

I was just doing some work, and work some reason the form_select would select every thing.

Here is what I coded.

form_select('', 'result][' .$payment->txnid, '', array('' => t('select result'), '1' => t('cleared'), '0' => t('dishonoured'))

And for some reason every option was selected.

I changed line 1329 in common.inc from ($value == $key ? ' selected="selected"' : '')) to ($value === $key ? ' selected="selected"' : '')) and it started working.

Is my form_select call wrong, or is there some difference between == and ===

Thanks.

Hmm,

After I wrote that last post I realized that booleans may be effected also. You might check this:

0 == FALSE; //true 0 === FALSE; //false

Which is one of the main reasons for the existence of "===". Some functions, such as some of the string searches, can return zero as a real data value if they happen to match on the first character of a string, but they also return FALSE if they don't match at all. "===" provides the calling routine a way to distinguish between 0 and FALSE. It can also be used to distinguish, with some of the more complex data types such as strings, whether two reference variables are for the *same* item or for two *different* items that have the identical contents.
