Alright so I hate creating forms so I'm wrting a class in PHP to take care of all the dirty work for me.
I'm running into one problem.

Here's the deal I have an array of all the form elements that I want to print out into a table. I want the user to be able to decide how many columns wide the table would be (default would be 2). I'm figuring most form elements can be 1 table cell wide, however text area's need to span at least 2 of the cells (Since I'm creating this I'm figuring textareas can span all columns).

Now the hard part is that I need to figure out how to loop through the array of elements and basiclly map them to a table cell. But I need to do it so that I get a nice table and nothing breaks.

Am I making sense here?
I've got a couple of ways I'm trying to go about it but they all seem clunky.

Could you post the format of the array?

well it's actually an 2D array.

It's basically it's a numbered array of hash's

$elm[0] = array("name" => "form_field_1", "type" => "text", "value" =>"whatever");
$elm[1] = array("name" => "form_field_2", "type" => "radio", "value" =>"whatever");
$elm[2] = array("name" => "form_field_3", "type" => "textarea", "value" =>"whatever");

just to make it simple to loop through and write the form fields, if I didn't want it in a table I could just do this

foreach ($elms as $var) {
if ($var['type'] != "textarea") {
echo "<input type=\"$var['type']\" value=\"$var['value']\" name=\"$var['name']\">";
} else {
echo"<textarea name=\"$var['name']\">$var['value']</textarea>";
}
}

there's more to each hash but this should give the idea.

Are any table cells supposed to be reserved for labels?

Are the form elements supposed to get mapped into the table from left to right in the order of the array filling up cells as completely as possible? If so, what you need is a variable that keeps track of how many columns are left in the current row.

code:
//$numCols = the number of desired columns
$remaining = $numCols
foreach($elms as $element) {
$formField = FORM ELEMENT FROM YOUR EXISTING CODE
//not enough columns? Start a new row and reset column counter.
if ($remaining - $element['cols'] < 0) {
while ($remaining > 0) {
print "<td>&amp;nbsp;</td>";
}
print "\n</tr><tr>\n";
$remaining = $numCols;
}
if ($element['cols'] > 1) $colspan = ' colspan="'.$element['cols'].'"';
else $colspan = '';
print "<td$colspan>$formField</td>";
$remaining -= $element['cols'];
}



Is this kind of what you mean?

Ahh very nice, that's exactly what I mean.
I didn't think of it as how many columns left, sometimes it's all about the mindset.

Thanks!
