FAQ: Technical Questions
I created a Virthos template from an existing HTML page. Now, when I use it, the text is no longer formatted correctly. Apparently, the browser is not finding the CSS definitions. What am I doing wrong?
CSS files, like image files and JavaScript files, cannot be located in the same directory as the template file. They must be in a subdirectory of the template file's directory, so that in a relative path specification, there is at least one forward slash.
wrong: <link rel="stylesheet" type="text/css" href="styles.css">
right: <link rel="stylesheet" type="text/css" href="resources/styles.css">
I built a template that allows uploading of PDF files, using the vtFile placeholder. When I create a new page based on this template, and upload a file, by web browser (Safari) sometimes hangs. In other words, I see a "wait" notice for up to an hour. Could it be that the PDF files are too big?
There is a fundamental problem with uploading large files using a browser. Many web servers have limits on the size of the file or the maximum time. If this happens, you will usually see an error message.
The endless "wait" notice is a problem that has been reported only for Safari. It points to a communications problem with this browser that occurs not only in connection with Virthos, but with any upload operation. Even though Virthos works quite well with Safari in all other respects, we can only advise you to try another browser, such as Firefox, if you often need to upload files.
If you want to use very large files with Virthos, such as MP3 clips or digital videos, we recommend that you load these files to the servers with an FTP program, and just maintain the URL's with Virthos. This means that you will not be using the vtFile-placeholder, but an ordinary text placeholder.
How can I enter HTML tags in a text field so that they will take effect? Every time I try it, the tags appear as plain text.
Generally, whenever you enter a special character in a text field, it is converted into the corresponding HTML entity when the page is displayed. So, for example, < becomes <, and > because > and so on. Thus, HTML formatting does not work unless you take some special steps. To prevent this automatic conversion and enable HTML formatting, you must label the placeholder involved with the "raw" suffix, as in this example: {{Body:raw}} When you use this method, it becomes your responsibility to manually place
tags in the surrounding text to designate line breaks. If you need only simple text formatting, you can take advantage of Virthos' own markup language, which is easier to use than HTML tags (see the chapter "Editing Text" in Part 2 of the User Manual). To use this formatting, label the placeholder as "styled," like this: {{Body:styled}} Starting with Virthos 2.0.2, a text field with this kind of placeholder is marked with a "T"-Symbol. By clicking on the symbol, you can bring up a window showing the various possibilities for marking up the text.
