Question

i have a list of photos like this:

<div class="upimage">
    <ul id="upimagesQueue" class="thumbs ui-sortable">
    <li id="upimagesKHGYUD">
        <a href="uploads/0002.jpg">
            <img src="uploads/0002.jpg" id="KHGYUD">
        </a>
    </li>
    <li id="upimagesNCEEKI">
        <a href="uploads/0003.jpg">
            <img src="uploads/0003.jpg" id="NCEEKI">
        </a>
    </li>
    <li id="upimagesPWSHUN">
        <a href="uploads/0003.jpg">
            <img src="uploads/0003.jpg" id="PWSHUN">
        </a>
    </li>
    <li id="upimagesOYJAQV">
        <a href="uploads/0004.jpg">
            <img src="uploads/0004.jpg" id="OYJAQV">
        </a>
    </li>
    </ul>
</div>

i want to make a function in jquery too get all the images in 1 array to be able to sent the array to php! the array i want to be in this form:

array(
    'image_id_1' => array(
        'image_src_1' => 'xyz.jpg',
    )
    'image_id_2' => array(
        'image_src_2' => 'xyz.jpg',
    )
    'image_id_3' => array(
        'image_src_3' => 'xyz.jpg',
    )
    'image_id_4' => array(
        'image_src_4' => 'xyz.jpg',
    )
)

how i can code this? thanks

Answer 1

var a = {};
$(".upimage img").each(function() {
  a[this.id] = $(this).attr("src");
});

would give you

a = {
  "KHGYUD": "uploads/0002.jpg",
  "NCEEKI": "uploads/0003.jpg",
  "PWSHUN": "uploads/0003.jpg",
  "OYJAQV": "uploads/0004.jpg"
};

Not sure why you would want a multi-dimensional array.

Answer 2

Start by using jQuery to select your images:

$('div.upimage > ul > li > a > img').each(function () { ... });

This will give you a function you can apply to each image in your markup. To make passing this array really easy, I'd recommend looking at using jQuery.param() to encode this array (the one returned by the selector) in URL parameters. That might get more than you need, though - you'll need to play around with the output.

Answer 3

var images = {};
$('.upimage li').each(function(){
  var $img   = $(this).find('img'),
      imgObj = {};

  imgObj[$img.attr('src')] = $img.attr('id');
  images[$(this).attr('id')] = imgObj;
});

// Then to send to php
$.post('url', images, function(){ /* success */ });

(it seems like you had the image src in their twice, so I just assumed you meant the li id first then the image src, either way, it's a small change)

DEMO: hhttp://jsbin.com/idovi3/6

from what you asked the jQUERY PLUGIN is ;-)

(function($) {

    $.fn.serializeImages = function() {
       //create the array...
       var toReturn    = [];
       //get the LI
       var els = $(this);
       //loop trought each LI ...
        $.each(els, function(i) {
         //get the Li id...
        var id = $(this).children().children().attr('id');
         //get the img src of the parent A parent IMG...
        var val = $(this).children().children().attr('src').split('uploads/')[1];
         //put each item in the array...
        toReturn.push( 
         // format the array...         
        id + ' => array( "image_src_' + i + '"' + ' => ' + val  + ', )'

            );           
        });   
        //join all into one single var for easy access.. 
        // \n can be whatever you want      
        var array =  toReturn.join('\n');

        return array; 
    }

})(jQuery);

  $(function () {
    var serie = $('ul li').serializeImages();
    alert(serie); 
  });

ECHO:

KHGYUD => array( "image_src_0" => 0002.jpg, )
NCEEKI => array( "image_src_1" => 0003.jpg, )
PWSHUN => array( "image_src_2" => 0003.jpg, )
OYJAQV => array( "image_src_3" => 0004.jpg, )
