TinyMCE Custom Dialog Box Example

In this post, I'm sharing how to add a custom dialog box in the TinyMCE WYSIWYG HTML editor. Adding a dialog box will able you to input dynamic records or data to your content editor using TinyMCE. Now I will show you how to do it with simple steps. For us to go further I have a tutorial on basic how-to install TinyMCE just visit if you need it.

Okay, let's continue.

 

Using editor.ui.registry on TinyMCE we are able to add our custom dialog box with the form with specified inputs.

 

Setting up TinyMCE dialog box

Add this code below to your TinyMCE configuration.

setup: function (editor) {

}

 

Add TinyMCE Registry

Then add the code below inside the setup function:

editor.ui.registry.addButton('custom_dialog', {
    text: 'Open Custom Dialog',
    onAction: function() {
        // Open a Dialog
        editor.windowManager.open({
            title: 'Custom dialog box',
            body: {
                type: 'panel',
                items: [{
                    type: 'input',
                    name: 'custom_data',
                    label: 'Custom data',
                    flex: true
                }]
            },
            onSubmit: function (api) {
                // insert markup
                editor.insertContent('Inserted custom data: ' + api.getData().custom_data);

                // close the dialog
                api.close();
            },
            buttons: [
                {
                    text: 'Close',
                    type: 'cancel',
                    onclick: 'close'
                },
                {
                    text: 'Insert',
                    type: 'submit',
                    primary: true,
                    enabled: false
                }
            ]
        });
    }
});

 

As you can see above code we have custom_dialog that is our dialog name we will call it to our toolbar settings. See the below example:

 

Insert Custom Dialog in Toolbar

Toolbar setting without custom_dialog:

toolbar:"undo redo | fontselect styleselect fontsizeselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image | codesample action section button",

 

Toolbar settings with custom_dialog:

toolbar: "undo redo | fontselect styleselect fontsizeselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image | codesample action section button | custom_dialog",

 

As you can see above we added "| custom_dialog" once added it will display the "Open Custom Dialog" to your TinyMCE editor toolbar.

 

See the complete setup below:

setup: function (editor) {
    editor.ui.registry.addButton('custom_dialog', {
        text: 'Open Custom Dialog',
        onAction: function() {
            // Open a Dialog
            editor.windowManager.open({
                title: 'Custom dialog box',
                body: {
                    type: 'panel',
                    items: [{
                        type: 'input',
                        name: 'custom_data',
                        label: 'Custom data',
                        flex: true
                    }]
                },
                onSubmit: function (api) {
                    // insert markup
                    editor.insertContent('Inserted custom data: ' + api.getData().custom_data);

                    // close the dialog
                    api.close();
                },
                buttons: [
                    {
                        text: 'Close',
                        type: 'cancel',
                        onclick: 'close'
                    },
                    {
                        text: 'Insert',
                        type: 'submit',
                        primary: true,
                        enabled: false
                    }
                ]
            });
        }
    });
}
