I'm trying to use Jquery to pass an array to an HTML form as follows:
$('form#'+ID1+' input#myArray').val(theArray);
Then my form is as follows
<input type="hidden" id="myArray" name="myArray">
I then serialize before calling an Ajax request:
var dataString=$('form#grid1').serialize();
But on the receiving script I get:
Uninitialized string offset: 1
Any ideas?
Thanks!
Here's my best guess from what you are showing in the question.
When you call the following, the array represented by theArray is converted into a comma-separated string and placed in the hidden input element. This is the case even if theArray is a nested array.
$('form#'+ID1+' input#myArray').val(theArray);
But on the server, you are trying to treat the posted "myArray" value as an array, so you get the following error:
Uninitialized string offset: 1
The problem is that "myArray" is not an array, but is a comma-separated string.
I recommend formatting the theArray value as JSON before setting it into the hidden input element, especially if it is a nested array. You can do this:
$('form#'+ID1+' input#myArray').val(JSON.stringify(theArray));
Then parse it to an object on the server side. I'm guessing from the error message that you are using PHP, so you would do something like this:
$myArray = json_decode($_POST['myArray']);
