Question

I have a javascript code that calls a function of a PHP api to insert a row in my database.

var url = 'http://myapi/OfertasVentaOnline/api.php?method=update&function=categoria&id='+id+'&idCategoria='+id_categoria+'&descripcion='+descripcion+'&format=json';


    $.getJSON(url, function (data){     

    });   

a sample of this url:

"http://myapi/OfertasVentaOnline/api.php?method=create&function=categoria&id=9999&idCategoria=3&descripcion=test%new%category&format=json"

in the url i replace the spaces for % in the descripcion parameter, as shown here the url is created correctly.

then I got my api who gets the call and decodes it. in the function that i use to decode and get the parameters:

$descripcion_cool = str_replace("%"," ",$_GET['descripcion']);

echo utf8_decode($descripcion_cool);

$query = 'INSERT INTO `Categorias`(`idCamping`, `idCategoria`, `descripcion`) VALUES (
                    "'.mysql_real_escape_string($_GET['id']).'",
                    "'.mysql_real_escape_string($_GET['idCategoria']).'",
                    "'.mysql_real_escape_string($descripcion_cool).'")';

this outputs this:

test new?tegoryINSERT INTO `Categorias`(`idCamping`, `idCategoria`, `descripcion`) VALUES (
                    "9999",
                    "3",
                    "test new�tegory")null

as you can see, php add some special characters to the url parameters. What am i doing wrogn ? thanks

PD: in my php file i tried to add:

header('Content-type: text/plain; charset=utf-8');

but it keeps doing the same.

Thanks in advance

Assuming you’re sending param values having spaces, you are encoding it by replace space with % . Actually, you don’t have to do that. You can use encodeURIComponent() method if you want to encode params/quesrystings being passed over. And if you want to encode url, then use encodeURI()

 description = encodeURIComponent(description);

var url = 'http://myapi/OfertasVentaOnline/api.php?method=update&function=categoria&id='+id+'&idCategoria='+id_categoria+'&descripcion='+descripcion+'&format=json';



    $.getJSON(url, function (data){     

    });   

This will safely enocode url.
