Set selected option of select tag & fetch_array

I have this code, there is no selected yet

I want to set selected option, already tried this in red, but its selected all value

then tried this in red

the result is getting error message like this, maybe its still not correct or cant use php code inside it :
Parse error: syntax error, unexpected T_IF in /home/username/public_html/test.php on line 29




tried put echo, just for test

the result is getting error message like this, so event cant print simple echo inside it :
Parse error: syntax error, unexpected T_ECHO in /home/username/public_html/test.php on line 29



please help share your knowledge guys, what is the right code to set selected in above code

GBU for all the answering

 

Something like this should do the trick :

        
while($datas=mysql_fetch_array($rs)){
       $selected = ($datas['product'] == 'test') ? 'selected' : '';       
       $data .= "<option value='$datas[product]' " . $selected . ">$datas[product]</option>";
}

PHP:

Hope it helps !

 

And that can also be done within the output (avoiding extra variables), by doing it like this:

   
while($datas=mysql_fetch_array($rs)) { 
$data .= "<option value='$datas[product]' " .( ($datas['product'] == 'test') ? 'selected' : '') . ">$datas[product]</option>";
}
