result should this.

<script type="text/javascript"> rrapionready.push(function() {     try {         rrapi.order({             transaction: <transaction_id>,             items: [                 { id: <product_id>, qnt: <quantity>,  price: <price>},                 { id: <product_id>, qnt: <quantity>,  price: <price> }             ]         });     } catch(e) {} }) </script>

i determine variable 'order.cart.items' , trying list array 'items[i].product.id' in tutorials:

var items = order.cart.items; (var in items) { ... }

but doesn't work me put in specific formatting above. returns error uncaught syntaxerror: unexpected token for.

rrapionready.push(function() {             try {             rrapi.order({             transaction: page.ordernumber,             items: [               (var j in items) {               { id: items[j].product.id, qnt: items[j].quantity,  price: items[j].product.price },               }                         ]                     });                     } catch(e) {}                 });

can please guide me how format array in such case? in advance!

you can't use for loop inside larger structure. javascript's for loops not expressions can evaluated value. rooted in imperative programming, not functional programming.

instead, should use map, does return new collection based on input collection:

rrapi.order({   transaction: page.ordernumber,   items: items.map(function (item) {     return { id: item.product.id, qnt: item.quantity, price: item.product.price }     }) })

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
