Variables in a Multiple select drop down

[scrbowler]

Help!  I'm trying to setup a form with a drop down where a person will select multiple (5 to be exact) items from the list and then submit the form.  How do I assign a specific variable to each selection on submit?

 

thank you

You can do it with an array I think, it has something to do with putting "[]" somewhere in the input element... then it will become a sub-array of the $_POST array.

 

That's all I can think of, at any rate. I've never done it before so I can't really help.

You need to create an array for these values, so here is an example.

 

HTML

<form>
   <select name="choices[]" multiple="multiple">
         <option>...</option>
         <option>...</option>
         <option>...</option>
         <option>...</option>
         <option>...</option>
         <option>...</option>
   </select>
</form>

 

Now when they submit the form, all the selected values will be in the array $_POST['choices']

How do I get a variable assigned seperately to each choice?  I need each to be handled seperately in the next stage.

Just grab them straight from the array. From the HTML example I posted above, to get the first value you would use choices[0], and so on.

 

Or you could use a foreach loop, it all depends on what your trying to do. So if this doesn't help you, explain more.

I've been giving this the ole college try and nothing seems to work for what I want when it comes to assigning a variable to the results of the form.

 

As you see in the code below I have a couple of efforts to make the variable available to the array list but I can't get it to post using the examples below.  Any help in assigning the variables to the choices will be greatly appreciated.  I'm trying to use the variables $driver1, $driver2 .... and so forth for the 5 selections from the form.

 

thanks
