Hiya,

I have the following code ... which only seems to result in one item ...
which is incorrect ... can anyone spot my problem?

Your subject line says "while-do" + array, following code contains a
"do-while" loop. We can't debug the script very well without a sample
input since we don't know how many times the loop "should" run. To debug
yourself, try using print_r() to see exactly what the following line of
code produces:

$options = explode(",", $armbase);

It's also useful for you to know that the list() function in your while
clause has return value void, AKA null, and so it will always be a false
statement and your loop will terminate on the first check.

Cheers,
Rob.



if ($armbase != "") {
$options = explode(",", $armbase);
$text .= '<table ><tr>';
$get_endRow = 0;
$get_columns = 8;
$get_hloopRow1 = 0;

do {
if($get_endRow == 0 && $get_hloopRow1++ != 0) {
$text .= '<tr>';
$text .= '<td valign="top" width="60">';
$text .= "<img
src='".e_BASE."images/options/armbase/".$value."'>";
$text .= '</td>';
$get_endRow++;
}
if($get_endRow >= $get_columns) {
$text .= '</tr>';
$get_endRow = 0;
}
} while(list($key,$value) = each($options));

if($get_endRow != 0) {
while ($get_endRow < $get_columns) {
$text .= '<td>&nbsp;</td>';
$get_endRow++;
}
$text .= '</tr>';
}

$text .= '</table>';

}

The purpose of the code is to create 8 colums and populate based on the
total results returned from the while-do check

Thanks in advance

Steven
