Setting the Image path in Tiny MCE

Open mind — Tue, 16 Sep 2008 07:13:15 +0000

The default for the image path of Tiny MCE is the relative url. So there may arise problems when the file is not shown in that particular server, for eg : sending a mail , so need to change some of the settings in tiny mce. This will help to do anything without any problems .
Eg: By default insert an image into tinymce like this from /test where / is the root directory tinymce seems to replace it with . The images folder is in the / (root).
So you can get rid of this by adding the below three lines
tinyMCE.init({
……
relative_urls : false,
document_base_url : “http://domainname.com/anyfolder/”,
convert_urls : false
});

The document_base_url is the relative url .
Refer to http://tinymce.moxiecode.com/examples/full.php full online examples.

Validation Class

Open mind — Wed, 21 May 2008 16:30:54 +0000

Searching for a upload progress meter , found an useful class for the form Validation. I dont think all have heard about this class and may not have worked in such a way. This class can automatically create forms with the validations that are needed with put any HTML. We just want to pass the required values.

You may be thinking , about which class I am boasting. Its none other than Manuel Lemos Forms generation and validation class. You can get the class from this link http://www.phpclasses.org/browse/package/1.html

You have to register first. Its just to send you the latest news and all. So do work with it. This class can add server side and client side form validation.
