Just one radio button selection for a whole form??

Hi guys,

I'm trying to do a simple form, that displays and updates information about a picture list. I'm using couple arrays, to pass the information from form, into the update queries, which update the mysql database. The problem is that one of the arrays is developed by a checkbox. When the checkbox is not selected it has a null value, which is not placed in the array. So the ending result are three arrays, two are the same, and one of them is a lot smaller. This makes a big mess with the update process. I have tried to replace the checkbox with a radio button, but this also gives me errors.

while($row = mysql_fetch_array($result))
	{
...
echo "<td>Album?<br>Yes<input type=\"radio\" name=album[] value=\"Yes\" CHECKED>"
. "<br>No<input type=\"radio\" name=album[] value=\"No\"></td>";
...

Once the form is populated with 10 pictures, each has the radio button selection, but I'm able to select just one radio button for the whole form, instead of ten. Is there a way to address this issue? Thanks.

Sounds like the issue is with how your doing the processing of the results, so how about posting that code. At a guess you need to look at the array keys when you loop through the results.

This is how i'm getting the arrays into new variables. The size and filename arrays are correct length, the albumarr is a lot shorter, since it's the one with the checkboxes.

$sizearr=$_REQUEST['size'];
$albumarr=$_REQUEST['album'];
$filname=$_REQUEST['filname'];

Than this is how I display some results.

for ($ii = 0; $ii < $maxn; $ii++) {
echo "Size : $sizearr[$ii]<br>"
. "Album : !$albumarr[$ii]!<br>"
. "Filename : $filname[$ii]<br><hr>";
}

when album is not set do you want to display size and file name anyway or display nothing in album is empty ?

dagon

for($ii= 0;$ii < $maxn;$ii++){
	if(isset($albumarr[$ii])){
		echo "Size : $sizearr[$ii]<br>Album : !$albumarr[$ii]!<br>Filename : $filname[$ii]<br><hr>";
	}
}

//or

for($ii= 0;$ii < $maxn;$ii++){
	echo "Size : $sizearr[$ii]<br>";
	if(isset($albumarr[$ii])){
		echo "Album : !$albumarr[$ii]!<br>";
	}
	echo "Filename : $filname[$ii]<br><hr>";
}

I would like to display size and file name, while album being empty. What happens usually during the update, I select pic# 1, 5, 11 to have an album, I click submit, and the new data shows that pic# 1, 2, 3 has an album, while the rest doesn't.
