Re: [PHP] Multiple selections
Thanks Mike and Ernest for the info on how to handle the "var[]" Multiple Select name more sensibly in JavaScript. Not even a workaround. By definition, in JavaScript x.y is identical to x['y'], so where for a simple field you might write: document.formname.myvar.value for a field named "myvar[]" you can write: document.formname['myvar[]'].value Cheers- David -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Not even a workaround. By definition, in JavaScript x.y is identical to x['y'], so
where for a simple field you might write:
document.formname.myvar.value
for a field named "myvar[]" you can write:
document.formname['myvar[]'].value

What happens when PHP parses form data is something like: variable is named "name"[] ? yes - $_REFERENCE['name'] = array(v1, v2, v3); no - $_REFERENCE['name'] ? v1; -- >O Ernest E.

As to my knowledge it is the only way.

I believe you can do this in JavaScript:
hf = form('myform');
he = hf.elements['myselect[]');
to get a handle to the form element.

I've made quite a number of JavaScripts controlled PHP dialogs containing
the [], they all work like a charm. There's only one thing you cannot do AFAIK:
myform.myvar[].value = 0;

Re: [PHP] Multiple selections
David -
Speaking of JavaScript, is there a way to block the Enter key? If I
have two buttons, the Enter key always pushes the one with focus.
What is the accepted way to handle this? With one button it is nice to
let the user press the Enter key and depress the one button - with two,
it can be a problem.

I just had to do some work with JavaScript and forms and the "myvar[]"
name clobbered JavaScript's access to form elements by name. I had to
do some ugly form.elements[x] looping to get at the "myvar[]" control.
This kind on external language hostility is not that cool, especially
toward such a common language as JavaScript.
My apologies to PHP if the language provides a workaround :)

Re: [PHP] Multiple selections
Many thanks!! One thing I do not understand in the "types" of variables is the use and referencing of a variable with the "[]". What I usually do is define a variable as $myvar = array(); And then I use the "[]" to refer to the elements. However, if I understand you suggestion, which works like a champ, the use of the "[]" tells the interpreter to treat $myvar as an array. Todd Marco Tabini wrote: Sure!

Sure it is - just name the listbox control "myvar[]" (note the angle
brackets). PHP will recognize this being an array, and you'll end up with
$myvar = array('select1','select2');

Re: [PHP] multiple selections in list/menu field
I didn't take the time to read your code too thoroughly, but remember to
have your select name to be anything with "[]" at the end of it, from the
look of your name field you have something inside the [], you need to get
rid of the rec_pd4 and just call it "x[]" or whatever you would like to call
it as long as the "[]" is empty :) I hope that made sense!

When I submit my form to my (say) > TestProg.php -- in the Hidden Input Field I only see the value for the > *last* item I selected... how can I see all the items I selected? If you want to allow the user to select multiple items, you should append '[]' to the end of the name of your select. Now when you get the value, it will be an array of the items they selected. You may run into a problem with your hidden input type on the second page - I'm not sure how PHP will handle things because your value will now be an array. You may want to write out a hidden field for each of the users selections - like: Regards, Sean On Sun, 13 May 2001, Jason Caldwell wrote: > > Thanks. > Jason > > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > To contact the list administrators, e-mail: [EMAIL PROTECTED] > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
