How can I use Multi Media Uploader in the WordPress Plugins?

2024/2/27 7:23:24

I try to add the multi uploading options in the wordpress plugins I repeated this code in the plugin(two times) only changing the id name.

                    <script language="JavaScript">
jQuery(document).ready(function($) {jQuery('#upload_image_button').click(function() {formfield = jQuery('#upload_image').attr('name');tb_show('', 'media-upload.php?type=image&TB_iframe=true');return false;});window.send_to_editor = function(html) {imgurl = jQuery('img', html).attr('src');jQuery('#upload_image').val(imgurl);tb_remove();};});</script>
<input id="upload_image" style=" margin-left:303px;" type="text" size="36" name="upload_image_template" value="<?php echo get_option('upload_image_template'); ?>" /><input id="upload_image_button" type="button" value="Browse" />

Whenever I try to upload a image that media frame comes and the uploading process are did successfully. But Insert Into Post fetch the correct url but pasted in different input box. For example:

1) [text box1] [browse Button]
2) [text box2] [browse button]

When I upload image with Text Box One that [insert post] that image path is shown in [text box 2] I am Not Sure Whether the Problem is mine or that script didn't support multi file upload option.

Answer

Here is the example how you can use the wordpress multimedia uploader for more than one field or as many fields. The JS code and html code looks like this

How it works

Add upload_image_button class on each upload button on the basis of this class click function triggers to fetch the wordpress multimedia uploader , see i have used the prev() property to get the previous element to the clicked one formfieldID=jQuery(this).prev().attr("id"); and then i have assigned the image url returned by uploader to formfieldID

 <input id="upload_image1" type="text" name="upload_image1" value="<?php echo $upload_image1;?>" /><input class="upload_image_button" type="button" value="Upload image 1" /><input id="upload_image2" type="text"  name="upload_image2" value="<?php echo $upload_image2;?>" /><input class="upload_image_button" type="button" value="Upload image 2" /><script type="text/javascript">//tb_show('', 'media-upload.php?TB_iframe=true');var upload_image_button=false;jQuery(document).ready(function() {jQuery('.upload_image_button').click(function() {upload_image_button =true;formfieldID=jQuery(this).prev().attr("id");formfield = jQuery("#"+formfieldID).attr('name');tb_show('', 'media-upload.php?type=image&amp;TB_iframe=true');if(upload_image_button==true){var oldFunc = window.send_to_editor;window.send_to_editor = function(html) {imgurl = jQuery('img', html).attr('src');jQuery("#"+formfieldID).val(imgurl);tb_remove();window.send_to_editor = oldFunc;}}upload_image_button=false;});})</script>

Also make sure you have included the necessary JS and CSS files of the uploader for this you have to add an action

<?php
function my_admin_uploader_scripts() {
wp_enqueue_script('media-upload');
wp_enqueue_script('thickbox');
wp_register_script('my-upload', WP_PLUGIN_URL.'/my-script.js', array('jquery','media-upload','thickbox'));
wp_enqueue_script('my-upload');
}function my_admin_uploader_styles() {
wp_enqueue_style('thickbox');
}
add_action('admin_print_scripts', 'my_admin_uploader_scripts');
add_action('admin_print_styles', 'my_admin_uploader_styles'); 
?>

Note: Also take care of one thing when you assign the uploader toyou input fields the control of uploader now assigns to the fields sowhen ever uploader will be called it assigns the image url to yourtext field , so this is the problem when you triggers the uploader youare unable to insert the images in the content area of the post forthis solution you have to store the previous control in some where andwhen you are done with uploader then reassign the control of uploaderto the previous function which i have provided in my JS code see belowhow it works

 var oldFunc = window.send_to_editor;window.send_to_editor = function(html) {imgurl = jQuery('img', html).attr('src');jQuery("#"+formfieldID).val(imgurl);tb_remove();window.send_to_editor = oldFunc;}

I have used this technique many times and it works perfect for me

Hope it makes sense
