php array with json_encode send jquery, then insert array values in input fields

Question

Have such php array

Array
(
[Title] => Text for title  
[Description] => Text for: description.
)

Then from php send back to jquery with echo json_encode($meta_back, JSON_HEX_QUOT|JSON_HEX_TAG|JSON_HEX_AMP|JSON_HEX_APOS);

In jquery with alert see this

{"Title":"Text for title  ","Text for: description."}

then

$.each( [ meta_from_url ], function( title, description ) {
alert( 'title_ ' + title + ' description_ ' + description );
});

And with alert see

title_ 0 description_ {"Title":"Text for title  ","Description":"Text for: description."}

What is incorrect in my code? title is 0 and whole data is in description

Have you tried using JSON.parse on the return value before attempting to loop over it? — user399666

Why loop over the properties of an object? Just access them directly

alert( 'title_ ' + meta_from_url.Title + ' description_ ' + meta_from_url.Description );

Your code is correct and is functioning properly.

$.each( [ meta_from_url ], function( title, description ) {
alert( 'title_ ' + title + ' description_ ' + description );
});

Here title is KEY and description is VALUE for the array. Your first entry has KEY value 0. Thus it is printing 0.

What you need is :

$.each( [ meta_from_url ], function( title, description ) {
alert( 'title_ ' + description.Title + ' description_ ' + description.Description );
});

Use it like this

var data = $.parseJSON( meta_from_url );
alert( 'title_ ' + data.Title + ' description_ ' + data.Description );

sorry all is ok. I was missing var meta_from_url = $.parseJSON( meta_from_url ); But in answer instead of data should be meta_from_url

The callback of your $.each expects ( index, object ) as parameters. Not two strings. That's why title_ is 0 (index) and description_ is the string representation of your whole object.
