Hi For those who has commented on Help with a unexpected T_ELSE this is the subsequent thread I couldn't post int he other account because accessibility issues.

In the code above below the query there will be an if and else statement sequence that is causing a parse errror: syntax error, as it fallows Parse error: syntax error, unexpected T_ELSE. Look at the if and else statment design and what's possiblly causing this error.

if {
  for (blabla) {
    if {

    }// end of if statement inside the for loop

  } //end of for loop.

} end of if statement 
else{ // line 379


}// end of else statement

What I believe is causing the T_ELSE syntax error above as I said in the last post is the if statement inside the for loop. Php believes that the else statement is working together with the if statement inside the for loop and what I want is the if statement outside the for loop work together with the else statement. The error looks like this:

PS everything that possibly causing the parse error is below the query. thanks.

The INTENDED DISPLAY in between the if and else would look like

foreach($result as $row)
    {  
    if (table cdkb) { 
      [1]qyt         image      name          price        remove
         1            ---       marina        $18.90        remove?    
         }end of if statement
    Else table dkb {
       1]qyt            Image         Name             Price                  Remove
         1               ---         marina         Small Tray  $18.90        remove? 
                                                    Medium Tray $30.24
                                                    Large Tray  $35.90
                      } // end of else statement

                      }//end of while loop

This is the array structure behind the INTENDED display!

<?php
$result = array(
        '0' => array('cdkb_id' => 'id 1',
            'image' => 'img 1',
            'name' => 'name 1',
            'price' => 'price 1'
            ),
        '1' => array('image1' => 'img 2',
            'name1' => 'name 2',
            'dkb_id' => array('0' => array('variety' => 'variety 2-1',
                         'price3' => 'price 2-1'
                        ),
                    '1' => array('variety' => 'variety 2-2',
                         'price3' => 'price 2-2'
                        ),
                    '2' => array('variety' => 'variety 2-3',
                         'price3' => 'price 2-3'
                        )
                    )
            ),
        '2' => array('cdkb_id' => 'id 3',
            'image' => 'img 3',
            'name' => 'name 3',
            'price' => 'price 3'
            ),
        '3' => array('image1' => 'img 4',
            'name1' => 'name 4',
            'dkb_id' => array('0' => array('variety' => 'variety 4-1',
                         'price3' => 'price 4-1'
                        ),
                    '1' => array('variety' => 'variety 4-2',
                         'price3' => 'price 4-2'
                        ),
                    '2' => array('variety' => 'variety 4-3',
                         'price3' => 'price 4-3'
                        )

The only thing on the way is the T_ELSE because there is an if in between the if and else statement inside the for loop....

Thank.

Notice this bit:

<?php 
} 
?> 
<?php 
else { 
?>

Have you tried NOT splitting the ending of the if and the else into two different code blocks? I strongly doubt the parser will maintain that kind of context: the first block works to terminate the if block, and since it doesn't read an else, it assumes you're done with it. Thus, the else you have in the next block is disconnected from your if.

The idea that the else would somehow connect to the innermost if is entirely wrong. The grammar would be far too broken if that were possible.

Your code definitely needs a major cleanup. Indentation isn't something you only hear about at a dentist's office. It's used to give your code visual structure and make it much easier to see at a glance where code belongs in a series of nest brackets. You essentially have NO indentation whatsoever, except for, oddly enough, the mysql query, which is beautifully formatted.

Since PHP's spitting out an 'unexpected else', that means you've got too many or too few brackets somewhere, or have something like this:

if ($condition) {
} else {
} else {
}

Clean up your code, use proper formatting, and I'd suggest using an editor, such as VI, which can help you find missing/extra brackets (the '%' command in VI, to bounce between matched brackets).

@Mark Byers below there is a simpler version of the code above and it has three if statement two before the else one inside a for each loop and another inside the for loop I want the one at the foreach loop to pair up with the else statement.

<?php
$totalCost=0;
foreach($result as $row)
{  
if($row['ckb_id']){ if statement that will match the else statement..
// Increment the total cost of all items
$totalCost += ($row["qt_y"] * $row["price"]);

?>

<div id="cart1">
<select name="<?php echo $row["cdkb_id"];?>" onChange="UpdateQty(this)">
<?php  print($row["cdkb_id"]);?>
<?php

for($i = 1; $i <= 30; $i++)
{
echo "<option ";
if($row["qt_y"] == $i) // if statement inside the for loop
{
echo " SELECTED ";
}
echo ">" . $i . "</option>";
}
?>
</select>
