[SOLVED] Send Multiple Values Using Checkboxes With Same Name?

[limitphp]

I have a bunch of checkboxes in a form.

They are all named genre.

 

When I submit the form, and try to catch the value of the checkboxes on the other side with:

$genres = $_POST['genre'];

 

It only gets the value of the very last checked checkbox.

In other words, if 2 checkboxes are checked, it will only get the value of the last checked one.

change names of your checkboxes to 'genre[]'

[limitphp]

change names of your checkboxes to 'genre[]'

 

Is there another way?

 

Thats the way I had it and it does work that way, but it messes up my javascript.

 

function checkRockGenres(){
var num_genres = document.frmGenres.genre.length;
var unchecked_flag=0;

if (document.frmGenres.allrock.checked){		
	document.frmGenres.genre[0].checked=true;
	document.frmGenres.genre[1].checked=true;					
	document.frmGenres.genre[2].checked=true;
	document.frmGenres.genre[3].checked=true;
	//CHECK TO SEE IF ALL GENRES ARE CHECKED
	for (var i=0; i <= num_genres-1; i++)
	{
		if (document.frmGenres.genre[i].checked==false)
			unchecked_flag = 1;		
	}
	if (unchecked_flag==1)
		document.frmGenres.allGenres.checked=false;
	else
		document.frmGenres.allGenres.checked=true;
}
else
{					
	document.frmGenres.allGenres.checked=false;
	document.frmGenres.genre[0].checked=false;
	document.frmGenres.genre[1].checked=false;					
	document.frmGenres.genre[2].checked=false;
	document.frmGenres.genre[3].checked=false;
}
}

 

Even when i change the line to:

var num_genres = document.frmGenres.genre[].length;

 

it still doesn't work.

Javascript using the "id" attribute, so just append the number onto the string it uses. PHP will use the array in the name. If you post the code of your form, we could help you better.

It continues all the way down to name="genre" value="17"

Ignore all the

if(strstr($genres, 'Alternatve')

I need to rework that part.

 

The problem with using id instead of name is this will not work:

var num_genres = document.frmGenres.genre.length;

Right?  That .length can only be used on form objects?

[limitphp]

solved....

 

I just changed all references of :

document.frmGenres.genre[x].checked=false;

 

to

 

document.frmGenres.elements['genre[]'][x].checked=false;

 

thanks guys...
