Norsk.Firefox Posted February 21, 2007 Share Posted February 21, 2007 Hello Anyone have a function that clean out not-allowed HTML tags? Example: <a href="test.php"><b>Hello</a> The a-tag goes trough, but the b-tag is replaced to <b> or that the funtion ends the tag. <- This is harder...

Jessica Posted February 21, 2007 Share Posted February 21, 2007 strip_tags() allows you to select which tags to allow, which is sort of what you want. Link to comment https://forums.phpfreaks.com/topic/39511-clean-html/#findComment-190632 Share on other sites More sharing options...
Norsk.Firefox Posted February 21, 2007 Author Share Posted February 21, 2007 looks like the opposite of what I want. It strips away tags i tell it to do, + these two warnings: Because strip_tags() does not actually validate the HTML, partial, or broken tags can result in the removal of more text/data than expected. This function does not modify any attributes on the tags that you allow using allowable_tags, including the style and onmouseover attributes that a mischievous user may abuse when posting text that will be shown to other users.

Jessica Posted February 21, 2007 Share Posted February 21, 2007 If you're going to allow every tag except just a few, that's not very safe. That's why I suggested strip_tags, you can allow just the ones you want. Wordpress has a html validator which fixes missing tags, perhaps if you looked through the code for it you might get some ideas.

Ninjakreborn Posted February 21, 2007 Share Posted February 21, 2007 Well actually they were right. If you wnat to strip out all tags except a few then you want stripped tags. $variable = striptags($variable, $allowed_tags);// allowed tags being an array of the allowed tags This will clean the variable of any tags you do not specify as being "allowed".
