For each outputting once from database


AdRock

Recommended Posts

What i am trying to do is output my products from my database into a form.  Each product (itemid) has it's own form.

 

My code is supposed to loop through the list of products, look at the itemid and if there is more than one of the same itemid, put it into a select list.  If there is only one itemid, take the other branch and ignore the select list.

 

The problem is I get one form with a massive select list but it has no values.

 

What I am expecting is a load of different forms which a different product in each form and one of the forms has a select box with 4 options for S, M, L and XL

 

Here is my code that is causing the problem.

 

while ($row = $result->fetchrow()) { 
		$superitem[$row['itemid']][] = $row;
	}

	foreach($superitem AS $subitem) {
		list($prodid,$item,$description,$price) = $subitem[0];

		if ($count % NUMCOLS == 0) echo "<tr>";  # new row
		echo '<td>';

		//Your normal code up until the select box...
		echo '<form method="post" action="" class="jcart">
				<fieldset>
					<input type="hidden" name="jcartToken" value="'.$_SESSION['jcartToken'].'" />
					<input type="hidden" name="my-item-id" value="2" />
					<input type="hidden" name="my-item-price" value="19.50" />
					<input type="hidden" name="my-item-url" value="http://yahoo.com" />';

		if(count($subitem) > 1) {
			echo '<li><select name="my-item-name" id="foo">';
			foreach($subitem AS $subsubitem) {
				echo "<option value='".$subsubitem['size']."'>".$subsubitem['size']."</option>";
			}
			echo "</select></li>";
		}
		else {
			echo '<input type="hidden" name="my-item-name" value="'.$item.'" />'; 
		}
		echo'<li>Price: $<span class="price">10.00</span></li>
					<li>
						<label>Qty: <input type="text" name="my-item-qty" value="1" size="3" /></label>
					</li>
				</ul>
			   
				<input type="submit" name="my-add-button" value="add to cart" class="button" />
			</fieldset>
		</form>';

		echo '</td>';
		$count++;
		$counter++;

		if ($count % NUMCOLS == 0) echo "</tr>\n";  # end row
	}

A couple other points/questions

 

1. No need to dump the DB results into an array if you are only then going to loop through the array one time. Just process the data as you extract the results from the database and save time and memory

2. Where is the constant "NUMCOLS" defined and have you validated that it does have a value?

3. The logic for starting/closing a table row will cause invalid HTML

4. I also see a problem with this logic

while ($row = $result->fetchrow())
{ 
    $superitem[$row['itemid']][] = $row;
}

foreach($superitem AS $subitem)
{
    list($prodid, $item, $description, $price) = $subitem[0];

Based upon what I see the foreach loop will iterate over each record from the DB results and $subitem will be an array of the fields in the record. You are then trying to use list() on "$subitem[0]". but, that will only be the first value of a record - not an array.

 

Please show the query you are using and the fields you are using from the database if you use "*" in your SELECT statement.

 

 

EDIT: Scratch that last statement, I now see that you are creating a multi-dimensional array.
