buy.php:

<form action="cart.php" method="post">
<?php foreach($product['varieties'] as $variety): ?>
    <input style="width:10px; margin-left:9px; " name="price[]" type="checkbox" value="<?php echo $variety['price'] . '_' . $variety['size']; ?>"  />';
<?php end foreach; ?>
</form>

cart.php:

list($aDoor, size)  = split('_', $_POST['price']); // line 207

if(empty($aDoor)) 
{
  echo("You didn't select any buildings.");
} 
else 
{
  echo "Sum of vlues = ".array_sum($aDoor);
}

In cart.php there is the following syntax error:

syntax error, unexpected ')', expecting T_PAAMAYIM_NEKUDOTAYIM in store/cart.php on line 207

I am expecting in cart.php to receive the two index values size and price independetly so I can use it and CSS it where ever i want. I am expecting that with the function list() and split() the variables variety and $aDoor with the price value will able to separate this two variables to be use wherever I want in cart.php

Help.

Answer 1

Missing a $ :

list($aDoor, $size) = split('_', $_POST['price']); // line 207

I think you are trying to do something like:

<?php
$aDoor = array();
$size = array();

foreach ($_POST['price'] as $p)
{
  list($a, $b) = explode('_', $p);
  $aDoor[] = $a;
  $size[] = $b;
}

if(empty($aDoor)) 
{
  echo("You didn't select any buildings.");
} 
else 
{
  echo "Sum of vlues = ".array_sum($aDoor);
}

?>

See this for a good primer. And Google is your friend :)

Answer 3

It's Hebrew. It means twice colon. It also happens when you miss the $, like you have.

Answer 4

@Konforce I test your script and it works good.

Sorry I don't know what I was saying but I have to work it like this to list $size and prices $aDoor with the total below. I just have to style it now.

<?php
list($aDoor, $size) = split('_', $_POST['price']);
$aDoor = array();
$size = array();

foreach ($_POST['price'] as $p)
{
  list($a, $b) = explode('_', $p);
  $aDoor[] = $a;
  $size[] = $b;
}

   if(empty($aDoor)) 
{
  echo("You didn't select any buildings.");
} 
else 
{
   $V = count($size);

for($i=0; $i < $V; $i++)
    {

      echo($size[$i] . " ");
    } 
     $A = count($aDoor);
 for($i=0; $i < $A; $i++)
    {

      echo($aDoor[$i] . " ");
    }


  echo "Sum of vlues = ".array_sum($aDoor);
}
?>

@konforce can you see at the begining where you have set up the variable $aDoor and $size as arrays?

$aDoor = array();
$size = array();

Well now I am adding another index value that is not an array it is an string

<input style="width:10px; margin-left:9px; " name="price[]" type="checkbox" value="' . $variety['price']. '_'. $variety['variety'] '_'. $product['name'].'"  />

you see the '. $product['name'].' well how can I receive it in cart.php in cart.php you have done the script as below but those are for arrays this time this one is not an array and I am seding it through the same form input.

$aDoor = array();
$size = array();

foreach ($_POST['price'] as $p)
{
  list($a, $b) = explode('_', $p);
  $aDoor[] = $a;
  $size[] = $b;
}
