Jquery window.send_to_editor

Question

Couldn\'t come up with a good title for this.

I\'ve got a build in WordPress where I have multiple image uploads using the built in WordPress media uploader. How it\

Answer 1

It sure is a hard issue to solve, not very well documented, but I think use is increasing with custom post types and all... I've imho improved somewhat on Paul Gillespie's code.

var up = null;
jQuery(document).ready(function() {
    up = new Uploader();
});
function Uploader() {
    this.storeSendToEditor = window.send_to_editor;
    this.uploadID = null;
    this.imgID = null;
}
Uploader.prototype.newSendToEditor = function(html) {
    imgurl = jQuery('img',html).attr('src');
    jQuery("#" + this.up.uploadID).val(imgurl);
    if(typeof(this.up.uploadFunc) == "function")
    this.up.uploadFunc(html, imgurl, this.up.uploadID);
    tb_remove();
    this.up.uploadID = '';
    window.send_to_editor = this.up.storeSendToEditor;
};
Uploader.prototype.upload = function(id,func){
    window.send_to_editor = this.newSendToEditor;
    this.uploadID = id;
    this.uploadFunc = func;
    tb_show('', 'media-upload.php?type=image&TB_iframe=true');
    return false;
}

Then use it by defining the custom function if you want to do more than just updating the input field for the database. I for one want to display the images within a wrapper div before uploading it.

var uploadFunc = function(html, imgurl, uploadID){
    // Do whatever you want.
};

And call it almost as before:

<input type="text" id="image_1" name="uploaded_image_1" value="" size="40" />
<input type="button" onclick="up.upload("image_1",uploadFunc);" title="Upload image" class="upload-button" id="add_image" value="Browse..."/>

Hope someone finds it useful!

This is maybe a little bit old topic but following your solutions i made my plugin work. None of the code above didn't worked completely to my solution, but combining them i made it work. I needed to be able to have 2 upload fields and one to accept video files and other images, and to be able also to post images and videos in post edit screen.

jQuery(document).ready(function() {

var orig_send_to_editor = window.send_to_editor;

 jQuery('.upload_image_button').click(function() {
     formfield = jQuery(this).prev('input');
         tb_show('Add Media', 'media-upload.php?type=file&TB_iframe=true');

         window.send_to_editor = function(html) {
             imgurl = jQuery('img',html).attr('src');
             if(jQuery(imgurl).length == 0) {
                 imgurl = jQuery(html).attr('href'); // We do this to get Links like PDF's
             }
             formfield.val(imgurl);
             tb_remove();
                    jQuery('#'+formfield.attr('name')).val(imgurl);


             window.send_to_editor = orig_send_to_editor;
         }

         return false;
     });
 });

And fields for upload are like this

    <tr>
    <td>
        <label for="image_1">Upload Thumbnail</label><br>
        <input type="text" name="image_1" id="image_1" value="" size="60" />
        <input class="upload_image_button button" type="button" value="Upload Thumbnail" />
        <br>
        You can also upload thumb from your PC using WordPress media manager(supported files are: .bmp, .BMP, .jpg, .JPG, .png, .PNG, jpeg, JPEG, .gif, .GIF).
    </td>
</tr>
<tr>
    <td>
        <label for="video_1">Upload Video</label><br>
        <input type="text" name="video_1" id="video_1" value="" size="60" />
        <input class="upload_image_button button" type="button" value="Upload Video" />
        <br>
        You can also upload video to stream directly from your website, using WordPress media manager(supported files are: .mp4, .MP4, .flv, .FLV, .f4v, .F4V).
    </td>
</tr>

This way i can upload image with thumbnail field, and video with video field, and add various images or gallery in post edit screen also.

Later with php i check if proper extensions are in proper upload fields and save them in custom fields, if not it leave the fields empty.

Maybe some will find this useful as i found your answers useful and helpful to me.

I use this to ensure other functionality works too for the editor and I also pass the id of the input field that I want the image in.

<?php
function customPostTypeUploader() {
    if(isset($_GET["post_type"])) {
?>
    <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
    <script type="text/javascript">
        var uploadID          = '';
        var storeSendToEditor = '';
        var newSendToEditor   = '';

        jQuery(document).ready(function() {
            storeSendToEditor = window.send_to_editor;
            newSendToEditor   = function(html) {
                                    imgurl = jQuery('img',html).attr('src');
                                    $("#" + uploadID.name).val(imgurl);
                                    tb_remove();
                                    window.send_to_editor = storeSendToEditor;
                                };
        });

        function Uploader(id) {
            window.send_to_editor = newSendToEditor;
            uploadID = id;
            formfield = jQuery('.upload').attr('name');
            tb_show('', 'media-upload.php?type=image&amp;TB_iframe=true');
            return false;
        }
    </script>
<?php
    }
}

add_action("admin_head", "customPostTypeUploader");
?>

Then use the input fields of a form in your meta box like this...

<input type="text" id="image_1" name="uploaded_image_1" value="" size="40" />
<input type="button" onclick="Uploader(image_1);" title="Upload image" class="upload-button" id="add_image" value="Browse..."/>

This example restores the window.send_to_editor() func by binding the tb_unload event as soju mentioned above.

var targetfield = '';
var orig_send_to_editor = window.send_to_editor;
jQuery('.fwb_uploadbtn').click(function() {
      targetfield = jQuery(this).prev('.fwb_uploadimg');
      tb_show('', 'media-upload.php?type=image&TB_iframe=true');

      //restore send_to_editor() when tb closed
      jQuery("#TB_window").bind('tb_unload', function () {
        window.send_to_editor = orig_send_to_editor;
      });

      //temporarily redefine send_to_editor()
      window.send_to_editor = function(html) {
        imgurl = jQuery('img',html).attr('src');
        jQuery(targetfield).val(imgurl);
        tb_remove();
      }
      return false;
});

Answer 5

I used this for uploading audio:

jQuery(document).ready(function($) {
    $('#upload_button').click(function() {
        tb_show('Upload a Podcast MP3 file', 'media-upload.php?referer=my-settings&type=audio&TB_iframe=true&post_id=0', false);
        return false;
    });
    window.send_to_editor = function(html) {
        console.log(html);
        var file_url = $($.parseHTML(html)).attr('href');
        console.log(file_url);
        $('#my_input_field').val(file_url);
        tb_remove();
    }
});

Answer 6

Here is my solution. This will allow you to upload any doc images, PDF's etc & will sort out the conflict issues that one will get with the text editors

var uploadID = ''; // setup the var in a global scope
var original_send_to_editor = window.send_to_editor;

jQuery('.upload-button').click(function() {
    uploadID = jQuery(this).prev('input'); // set the uploadID variable to the value of the input before the upload button
    formfield = jQuery('.upload').attr('name');
    tb_show('', 'media-upload.php?TB_iframe=true');
    uploadBAR(); // Call if needed
    return false;
});

function uploadBAR() {
    window.send_to_editor = function(html) {
    imgurl = jQuery(html).attr('href');
    uploadID.val(imgurl); /*assign the value of the image src to the input*/
    tb_remove();

    window.send_to_editor = original_send_to_editor;//restore old send to editor function
    };
}
