twilitegxa Posted July 31, 2009 Share Posted July 31, 2009 Is there a way to write some if statements that will name a variable based on what option a user selects in the options?

I need to take the first option, and if they choose it, then take the second option value, and multiply it by a specific amount (in this case 1, but ill be other numbers in other cases), and then set that to a variable name so it can be used in a function or something later on the page. Can anyone help me write this properly? Quote Link to comment Share on other sites More sharing options...
lonewolf217 Posted July 31, 2009 Share Posted July 31, 2009 I do not think that is possible with the way you are doing it. Currently you are submitting the form via javascript and doing something (not entirely sure what) with the data. PHP would have no way of knowing the values of these options since you cannot use javascript to call php functions, and you cannot use form data in php without submitting the form. However, perhaps something like this would be possible using jquery/ajax because you can then use the javascript submit to pass data to a backend php page to process the data how you want it, and then display it on the main page Quote Link to comment Share on other sites More sharing options...
twilitegxa Posted July 31, 2009 Author Share Posted July 31, 2009 I will see if I post it to the JavaScript section and see if anyone can help. Thanks! Quote Link to comment Share on other sites More sharing options...
