Re: More php trouble *pulling hair out*

At line 20 it should be:

if (!$columns || $i % $columns != 0) {
for (; $columns && $i % $columns != 0; $i++) {
echo "<td>&nbsp;</td>\n";
}
echo "</tr>\n";
}

Hi,

Here's how you can print any number of columns.

The mod (%) test tells you if the item is either the first or last
column.

[products.php]
<?

error_reporting(E_ALL | E_STRICT);

function printGrid($columns = 2)
{
$path = dirname(__FILE__) . '/list.csv';
if (($csv = fopen($path, 'r')) === false) {
trigger_error("Failed to open CSV file.", E_USER_ERROR);
} else {
$sz = 1000;
for ($i = 0; ($item = fgetcsv($csv, $sz)) !== false; $i++) {
if ($columns && $i % $columns == 0) echo "<tr>\n";
// Print the product
echo '<td>' . ($i + 1) . ". {$item[0]}</td>\n";
if ($columns && $i % $columns == $columns - 1) echo "</tr>\n";
}
fclose($csv);
for (; $columns && $i % $columns != 0; $i++) {
echo "<td>&nbsp;</td>\n";
}
}

}

?>

<h1>Products</h1>

<table cellpadding=3 cellspacing=0 border=1>
<? printGrid() ?>
</table>

Works GREAT...Except my aunt wants 2 columns instead of one. I have an
idea on how to do it, but I'm having trouble.

I'm wanting to insert a line of code that utilizes my function up
there in the head.

$maxcol=csv_entrycount($handle);

in my code towards the top of the script, you'll see where I blatantly
advertised that I wanted to place something there... that's what I
want to put there. But when I do, it makes the page...disappear.

Normally I'd think that the code was just wrong and I needed to fix
it. (and that may still be the case), but I tried the SAME bit of code
in a much less codey page for testing purposes and it WORKED. I'm so
frustrated. I've been at this for the past week now. Can anyone help?
