Iteration Issues

[s_ainley87]

Hello Everyone,

 

I have built session cart but I am issues iterating through it and getting the data from it I need, basically I need from the array the catergory name, product name, price and quantity but have no idea how to do it :-(, the array looks like this,

 

Array ( [cart] => Array ( [57] => Array ( [quantity] => 1 [price] => 249.99 ) [74] => Array ( [quantity] => 1 [price] => 69.99 ) ) )

 

how would I get all this data from the array using a foreach, I have no idea how to form it :-(.

 

Please Help Thanks

As u have a multidimensional array, ull need nested foreach() loops to go through each array level. Take a look at the following example:

 

<?php
$cart = array('cart' => array(57 => array('quantity' => 1, 'price' => 249.99),
		      74 => array('quantity' => 1, 'price' => 69.99)));
						  
foreach($cart as $Cval){ //loop through the 'cart' values
foreach($Cval as $Pkey => $Pval){ //loop through array(57.....
	echo 'This index: ' . $Pkey . ' has these values<br />';
	foreach($Pval as $key => $val){ //loop through array('quantity'.....
		echo $key . ': ' . $val . '<br />';
	}
	echo '<br />';
}
}
?>

thankyou, however  theses values

$cart = array('cart' => array(57 => array('quantity' => 1, 'price' => 249.99),
		      74 => array('quantity' => 1, 'price' => 69.99)));

will not also be the same how can i resolve that?

The actual values doesnt matter as long as the array has the stated structure. Otherwise u have to modify the script, by adding/removing a foreach loop, basing on the depth of the array. Guess ure not meaning that the array will have dynamic depth as it would need a recursive approach.

I am sorry i dont really understand the ins outs of it, I am new to this PHP lark.

 

What i need it to do is loop through the cart regarless and of what what is held in the cart and how many products are in it, I then need to some how get those values and hold then in hidden form fields.

Look, if u have this array:

 

$cart = array('cart' => array(57 => array('quantity' => 1, 'price' => 249.99),
		      74 => array('quantity' => 1, 'price' => 69.99)));

 

or this array:

 

$cart = array('cart' => array(57 => array('quantity' => 1, 'price' => 249.99),
		      74 => array('quantity' => 1, 'price' => 69.99)));
                                            24 => array('quantity' => 2, 'price' => 49.99)));
                                            18 => array('quantity' => 1, 'price' => 54.99)));
                                            63 => array('quantity' => 3, 'price' => 144.99)));

 

The script will still work. Assuming those 57, 74 etc are the ids of the products, guess that array structure will do the work. To pass those values in hidden inputs, consider the following but modify it for your needs:

 

<?php
echo "<form name='myForm' method='post' action='mypage.php'>";
$cart = array('cart' => array(57 => array('quantity' => 1, 'price' => 249.99),
		      74 => array('quantity' => 1, 'price' => 69.99)));
foreach($cart as $Cval){
foreach($Cval as $Pkey => $Pval){
	foreach($Pval as $key => $val){
	          echo "<input type='hidden' name='" . $Pkey . "' value='" . $val . "' />";
	}
}
}
echo '</form>';
?>

i appreciate your help, but I cannot predict what product the user will choose so how can I decide what products numbers to give the array?
