I’m searching, unsuccessfully unfortunately, for a ThickBox replacement used in Media Uploader.
Any search fails on how to leverage Media Uploader and nothing about a script used for modal windows.
Can somebody help me? Is there a way to use the same modal as Media Uploader is using, but to put custom content in it like it was possible with ThickBox?
For what it’s worth, I have integrated the new media uploader in a plugin which allows the admin to select or upload media from the standard media dialog instead of having to copy/paste URLs, and it seems to work well.
I posted an answer here that might be what you’re looking for.
Tom McFarlin has a tuts+ series in the works as of last month.
Other links that may help:
My understanding of your question is that you want to use a popup that has contents other than Media Uploader. To achieve this follow these steps:
Add this code to include the thickbox script.
Add class=’thickbox’ to any clickable element that will show the popup.
Notice in the last code there is inlineId parameter. This will be the code to be displayed inside popup box.
I hope this helps
