Todays, Summernote WYSIWYG editor is a very simple and super fast bootstrap editor. Summernote WYSIWYG editor is a javascript library and it’s provide to use their tools for file upload, text bold, color, italy font etc.

We can simply use summernote by following their website “summernote.org”. They provide docs for complete guide and we can use in a minute. They also provide file uploading options, But not more for validation like image max size should be 1mb, file mime type should be png, jpg etc. So we can’t do it that simple.

However, In this post i will show you how to add custom jquery validation for image upload. we will restrict image size while uploading the image, we will allow to upload only png, jpg and jpeg image file only. So you can do it simply by following jquery code:

Jquery Code:

$(document).ready(function() {

$('#summernote').summernote({

height: 300,

callbacks: {

onImageUpload: function(image) {

var sizeKB = image[0]['size'] / 1000;

var tmp_pr = 0;

if(sizeKB > 200){

tmp_pr = 1;

alert("pls, select less then 200kb image.");

}

if(image[0]['type'] != 'image/jpeg' && image[0]['type'] != 'image/png'){

tmp_pr = 1;

alert("pls, select png or jpg image.");

}

if(tmp_pr == 0){

var file = image[0];

var reader = new FileReader();

reader.onloadend = function() {

var image = $('<img>').attr('src', reader.result);

$('#editor').summernote("insertNode", image[0]);

}

reader.readAsDataURL(file);

}

}

}

});

});

So, above simple jquery code, you can understand how simple we write custom jquery validation and you can add your code. I also provide full example for this example so simply take bellow index.html file and see in your local:

index.html

<!DOCTYPE html>

<html>

<head>

var sizeKB = image[0]['size'] / 1000;

var tmp_pr = 0;

if(sizeKB > 200){

tmp_pr = 1;

alert("pls, select less then 200kb image.");

}

if(image[0]['type'] != 'image/jpeg' && image[0]['type'] != 'image/png'){

tmp_pr = 1;

alert("pls, select png or jpg image.");

}

if(tmp_pr == 0){

var file = image[0];

var reader = new FileReader();

reader.onloadend = function() {

var image = $('<img>').attr('src', reader.result);

$('#editor').summernote("insertNode", image[0]);

}

reader.readAsDataURL(file);

}

}

}

});

});

</script>

</html>

You can see above example and it’s pretty simple.
