In this post, I will show you how to implement a Media Selector jQuery plugin which enables you to select single or multiple images (or any other elements) from a gallery.

## How to use the single/multiple image selector jquery plugin?

## Step 1: Insert images
Insert images with check icons into labels of CSS class **'image-checkbox'**. Remember to assign a unique ID to each image element utilizing the **'su-media-id'** attribute.

```php
<label class="image-checkbox">
    <img su-media-id="orange"
       src="img1.jpg" />
    <i class="fa fa-check"></i>
</label>
<label class="image-checkbox">
    <img su-media-id="apple"
       src="img2.jpg" />
    <i class="fa fa-check"></i>
</label>
<label class="image-checkbox">
   <img su-media-id="grapes"
        src="img3.jpg" />
    <i class="fa fa-check"></i>
</label>
 
```

## Step 2: Add Toggle Checkbox
Add a checkbox to toggle between Single Select and Multiple Select.

```php
<input type="checkbox" class="custom-control-input" id="allowmultiple">
    <label class="custom-control-label" for="allowmultiple" style="cursor: pointer;">Select
    Multiple</label>
```

## Step 3: Set Media Preview
Make an outcome container wherein the Media Selector shows a JSON string containing the image IDs you select.

```php
<div id="selectedmediapreview"></div>
```

## Step 4: Load Styles
Load the CSS to style your image checkboxes.

```php
.image-checkbox {
    cursor: pointer;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
    border: 3px solid transparent;
    box-shadow: 0 0 4px #ccc;
    outline: 0;
    margin: 4px;
    border-radius: 12px;
}

.image-checkbox-checked {
    border-color: #2196f3;
}

img {
    border-radius: 8px;
    max-height: 160px !important;
    max-width: -webkit-fill-available;
}

.image-checkbox i {
    display: none;
    color: #2196f3;
}

.image-checkbox-checked {
    position: relative;
}

.image-checkbox-checked i {
    display: block;
    position: absolute;
    top: 10px;
    right: 10px;
}
```

## Step 5: Load the jQuery Library assets

```php
 <script src="https://code.jquery.com/jquery-3.6.0.slim.min.js" integrity="sha256-u7e5khyithlIdTpu22PHhENmPcRdFiHRjhAuHcs05RI=" crossorigin="anonymous"></script>
    <script src="assets/js/scripts.js"></script>
```

## Step 6: Load the jQuery script
Initialize the JavaScript to activate the image selector.

```php
jQuery(function ($) {
    var mediaArray = [];
    var selectedMediasId;
    var isMultipleAllowed = false;
    $('#allowmultiple').click(function () {
        isMultipleAllowed = $('#allowmultiple').is(':checked') ? true : false;
        $('.image-checkbox-checked').each(function () {
            $(this).removeClass('image-checkbox-checked');
        });
        mediaArray = [];
        $('#selectedmediapreview').html('');
    });


    $(".image-checkbox").on("click", function (e) {
        var selected = $(this).find('img').attr('su-media-id');
        //console.log(selected);
        if ($(this).hasClass('image-checkbox-checked')) {
            $(this).removeClass('image-checkbox-checked');
            // remove deselected item from array
            mediaArray = $.grep(mediaArray, function (value) {
                return value != selected;
            });
        }
        else {
            if (isMultipleAllowed == false) {
                $('.image-checkbox-checked').each(function () {
                    $(this).removeClass('image-checkbox-checked');
                });
                mediaArray = [];
                mediaArray.push(selected);
            } else {
                if (mediaArray.indexOf(selected) === -1) {
                    mediaArray.push(selected);
                }
            }
            $(this).addClass('image-checkbox-checked');
        }
        //console.log(selected);
        console.log(mediaArray);
        selectedMediasId = mediaArray.join(",");
        console.log(selectedMediasId);
        $('#selectedmediapreview').html('<div class="alert alert-success"><pre lang="js">' + JSON.stringify(mediaArray.join(", "), null, 4) + '</pre></div>');
        //console.log(isMultipleAllowed);
        e.preventDefault();
    });
});
```
