you want to upload image so we create a js file and write some code in functions.php.
But first we create custom upload meta field.
In your function.php or where you write a code for register custom taxonomy and write this code:
First we create custom meta term field
add_action('product_categories_add_form_fields', 'add_term_image', 10, 2);
function add_term_image($taxonomy){
?>
<div class="form-field term-group">
<label for="">Upload and Image</label>
<input type="text" name="txt_upload_image" id="txt_upload_image" value="" style="width: 77%">
<input type="button" id="upload_image_btn" class="button" value="Upload an Image" />
</div>
<?php
}
Write your custom taxonomy before _add_form_fields in add_action() Like I write above"product_categories"_add_form_fields
Then we save meta term value
<?php
add_action('created_product_categories', 'save_term_image', 10, 2);
function save_term_image($term_id, $tt_id) {
if (isset($_POST['txt_upload_image']) && '' !== $_POST['txt_upload_image']){
$group = '#' . sanitize_title($_POST['txt_upload_image']);
add_term_meta($term_id, 'term_image', $group, true);
}
}
?>
Same as above write your taxonomy name after created_ in add_action Like created_product_categories
Now we create meta term field for edit
add_action('product_categories_edit_form_fields', 'edit_image_upload', 10, 2);
function edit_image_upload($term, $taxonomy) {
// get current group
$txt_upload_image = get_term_meta($term->term_id, 'term_image', true);
?>
<div class="form-field term-group">
<label for="">Upload and Image</label>
<input type="text" name="txt_upload_image" id="txt_upload_image" value="<?php echo $txt_upload_image ?>" style="width: 77%">
<input type="button" id="upload_image_btn" class="button" value="Upload an Image" />
</div>
<?php
}
Now save the edited value
add_action('edited_product_categories', 'update_image_upload', 10, 2);
function update_image_upload($term_id, $tt_id) {
if (isset($_POST['txt_upload_image']) && '' !== $_POST['txt_upload_image']){
$group = '#' . sanitize_title($_POST['txt_upload_image']);
update_term_meta($term_id, 'term_image', $group);
}
}
Now we Move to **JS File for WordPress Media Uploader**
media-uploader.js
jQuery(document).ready(function($){
// Instantiates the variable that holds the media library frame.
var meta_image_frame;
// Runs when the image button is clicked.
$('#upload_image_btn').click(function(e){
// Prevents the default action from occuring.
e.preventDefault();
// If the frame already exists, re-open it.
if ( meta_image_frame ) {
meta_image_frame.open();
return;
}
// Sets up the media library frame
meta_image_frame = wp.media.frames.meta_image_frame = wp.media({
title: meta_image.title,
button: { text: meta_image.button },
library: { type: 'image' }
});
// Runs when an image is selected.
meta_image_frame.on('select', function(){
// Grabs the attachment selection and creates a JSON representation of the model.
var media_attachment = meta_image_frame.state().get('selection').first().toJSON();
// Sends the attachment URL to our custom image input field.
$('#txt_upload_image').val(media_attachment.url);
});
// Opens the media library frame.
meta_image_frame.open();
});
});
