Get Value from PHP Codeigniter to AJAX

Question

I have a variable in php and i want to check in ajax if this variable value is word "RMA" or not.

If the variable value is "RMA" then my url ajax will change to

    url: "<?=site_url('equip_request/get_json_selected');?>",

else

url: "<?=site_url('spares/get_json_selected');?>",

Code:

$erf_header->purpose = "RMA"; // this is just an example variable and value

and this is my function in ajax

if ($.cookie("spare-items-loaded") == 1) {
                if ($.cookie("spare-items")) {

                    cookie_items = $.cookie("spare-items").split(",");

                    if (cookie_items.length > 0) {

                        var request = $.ajax({
                                url: "<?=site_url('spares/get_json_selected');?>",
                                type: "POST",
                                data: {
                                    ids: cookie_items.join(","),
                                },
                                dataType: "json",
                                success: function(data) {  

                                    var template = null;
                                    var source   = null;
                                    var result   = null;

                                    result   = jQuery.parseJSON(JSON.stringify(data));

                                    source   = $("#spare-loop-list").html();
                                    template = Handlebars.compile(source);

                                    $("#equipment-list").append(template(result));  

                                    cookie_items = jQuery.unique(cookie_items);             
                                    $("#total-spares").html(cookie_items.length);
                                }
                            });                 
                    }
                } else {
                    $("#equipment-container").hide();
                    $("#total-spares").html( 0 );               
                }
            }

First we decide which URL we'll be sending POST data to.

$url = ''; //Initialize $url as global variable

if($var === "RMA"){
    $url = "site_url('equip_request/get_json_selected')";
}else{
    $url = "site_url('spares/get_json_selected')";
}

Then parse in the $url into the ajax request.

url: "<?=$url;?>",

On a sidenote, i'd be weary when using <?=, here is why.

Additionally, by default, JS can only parse PHP if it's inline of a .php file, if it's not, see your options here.

you need to echo $url if it's in the javascript.

Jack Over a year ago

<?= is shorthand to echo.

Bryan Over a year ago

yeah, <?=$url?> would do it.
