Passing javascript array in the url

Question

How can I pass an array in the url in javascript?

I tried this :

http://codeigniter/index.php/AssistanceMonitoringModule/assistanceMonitoring/getReport?remarks="+stat+"&sortBy="+sortBy+"&fromDate="+fromDate+"&toDate="+toDate+"&area="+area;

which the remarks is the one being catch in PHP as an array and stat is the javascript array being supplied in the remarks. Is there any solution for that?

whenever a time catch the remarks in PHP which I use $this->input->get_post('remarks') (since im using codeigniter) i got an error 'Invalid argument supplied for foreach()'

Thans for your help. :)

• Sacho: get_post implies you're expecting a POST method? At any rate, you can encode an array for php like so: array[]=x&array[]=y...and so on.

Answer 1

You can encode the array as JSON, with JSON.stringify and decode it in PHP with json_decode. Don't forget to use encodeURIComponent for the values in the URL, otherwise you might not get the URL you expected.

• akoDwin: I already try an alternative solution, but Thanks aNyway. :) my solution, exploding the string into an array. :P Works but isnt reliable.

Answer 2

Try like this.

http://codeigniter/index.php/AssistanceMonitoringModule/assistanceMonitoring/getReport?get[remarks]="+stat+"&get[sortBy]="+sortBy+"&get[fromDate]="+fromDate+"&get[toDate]="+toDate+"&get[area]="+area;
foreach($_GET['get'] as $get){
 ....
}

• Felix Kling: That's not what the OP wants and what you propose is unnecessary in any case. If someone wanted to iterate over all query parameters in the URL, they can just do foreach($_GET as $value){. There is no need to only use a single query parameter.
• user3650948: Yeah you are right but, still answers the main questoin :D. There are many way to this question.
• Felix Kling: Not really. OP wants to send the value of remark as array. I.e. stat is an array. He doesn't want to make every parameter an element of an array.
