AJAX functions don't pass JSON with arrays properly

[lukebrookhart]

With all the AJAX functions (ie. .load, .post .get, etc) the JSON data that is sent to the server does not pass the array data properly. Due to the way arrays are passed to web servers, the names of the array variables need to be concatenated with "[]" to signal to the server that there is more than one value.

Example:

$('#property_search_results').load('search.php', {towns:['Apalachin','Owego','Binghamton']});

Web servers will first define the "town" variable with "Apalachin". It will then immediately overwrite "Apalachin" with "Owego", and then overwrite "Owego" with "Binghamton".

If we change the variable name to towns[] within the AJAX functions, web servers will know that this is an array of values and all will be well. This is same way that web browsers pass an array of values for one variable in forms and query strings.

Will look into it.

This is the change, but I think I won't be able to apply it as many people/servers don't expect this to happen.

According to ​this, the index/key shouldn't be specified.

So I'll have to close this, you can apply the diff to your file if you want, or you can just use:

{
 'towns[]':['Apalachin','Owego','Binghamton']
}

That should work as expected.
