Here is how to create a POPUP window in WordPress with a content of your choosing.
For the popup we need a Page w/o a theme, so let’s do this :
- Install the “Blank Slate” plugin.
- Create New Page
- Leave the Title empty
- Set in Page property Template=”Blank Slate”
- Add whatever content you want
- Because there is no Title, we need set a Permalink so that it is human readable, let say : your-site/blah
- Publish the page
- Go to the page you want to have the popup window show up when you click a link
- Add the following code :
<a href='' onclick='window.open("https://your-site/blah/","window-name","width=400,height=320");' target='blank'>Popup window</a>
If you have an original element to hide use this, so that it looks like the element pop up from the page :
<a href='' onclick='window.open("https://your-site/blah/","window-name","width=400,height=320");document.getElementById("orig-blah").style.display="none";' target='blank'>Popup window</a>
