JSON help

[steviez]

Hi,

 

I have two select boxes on my site like this:

 

Language - Level

 

and the user can keep adding more sets of select boxes. I need the data posted to be JSON encoded like this:

 

{"LANG1":["German","Beginner"],"LANG2":["Polish","Advanced"]} etc

 

How can i make this happen?

[trq]

json_encode.

[steviez]

json_encode.

 

Sorry i should have said that i am already using this function but cant get the result i need. My code is this:

 

if(isset($_POST))
	{
	    foreach($_POST as $key => $val)
	    {
                echo json_encode(array($key => array($val['lang'], $val['level'])));
	    }
	    
	}

 

but it does not output the required:

 

{"LANG1":["German","Beginner"],"LANG2":["Polish","Advanced"]}

 

 

[trq]

What does....

 

echo '<pre>';
print_r($_POST);
echo '</pre>';

 

look like?

What does....

 

echo '<pre>';
print_r($_POST);
echo '</pre>';

 

look like?

 

well at the moment with 4 of each field selected i get:

 

Array
(
    [lang] => Array
        (
            [0] => german
            [1] => polish
            [2] => english
            [3] => blaaaa
        )

    [level] => Array
        (
            [0] => 2
            [1] => 4
            [2] => 1
            [3] => 3
        )

)

[trq]

All you need do is....

 

echo json_encode($_POST);

 

then. The array is already how you need it.

that gives me:

 

{"lang":["german","polish","english","blaaaa"],"level":["2","4","1","3"]} 

 

and i need:

 

{"german":"2","polish":"4", "english":"1","blaaaa":"3"} 

[trq]

That is not at all what your original post described.

[steviez]

That is not at all what your original post described.

 

yes it is... except i wanted the results as:

 

{"LANG1":["German","Beginner"],"LANG2":["Polish","Advanced"]}

 

I changed it as i thought it might get more complicated if not

Try something like this (I initialize the $_POST array in this code for testing only):

<?php
$_POST = Array
(
    'lang' => Array
        (
            'german',
            'polish',
            'english',
            'blaaaa'
        ),

    'level' => Array
        (
            2,4,1,3
        )

);
$tmp = array();
$i=1;
foreach($_POST['lang'] as $ind => $lang) {
        $tmp['lang'.$i] = array($lang,$_POST['level'][$ind]);
        $i++;
}
$js = json_encode($tmp);
echo $js . "<br>\n";
?>

The output is

{"lang1":["german",2],"lang2":["polish",4],"lang3":["english",1],"lang4":["blaaaa",3]}
