Remove quotes when reading from sessionStorage and sending to php using jquery

Question

I'm storing different values in the sessionStorage during a longer process. At the end i want to read all the data and send it to my php backend using ajax. The problem is that php seems to take every value including quotes. Here is what i got:

// Reading data from storage
var imgb = sessionStorage.getItem("img_b_id");
....
// perpare data
var oData = {
            imgb: imgb,
            ...
};

// Sending data
$.post( "../php/direct/create.php", oData).done(function(data) {
    if(data==true) {
        window.open("step5.php", "_self");
    } else {
        alert("Error: " + data.toString()); 
    }
});

This is working perfectly fine. However, php will read the value of imbg with quotes. Example:

echo $_POST['imgb'];
/* Returns "asd" instead of asd

The image below shows that my data is stored without the quotes (chrome sessionstorage screenshot)

Do you have any suggestions on how to solve this. I currently replace the quotes, but I'd love to fix this problem at it's root...

Answer 1

I have tried your code ( with Firefox and Chrome ) and

echo $_POST['imgb'];

Print the string without quotes. Consider that even if you set a number in the session storage, for example

sessionStorage.setItem("img_b_id", 100);

The value is received at server by PHP as a string so you can convert it with PHP functions intval(), floatval() etc.
