Code: Select all
[url]http://www.photomacrography.net/forum/viewforum.php?f=29
[/url]
A more subtle form often happens to me when I'm attempting to associate a URL with some other text, for example: "Check in the Frequently Asked Questions forum."
The proper way to code this line (as it's done above) is:
Code: Select all
Check in the [url=http://www.photomacrography.net/forum/viewforum.php?f=29]Frequently Asked Questions forum[/url].
But the whole post will disappear if the line is mis-coded ever so slightly, for example by forgetting to replace ] by = :
Code: Select all
Check in the [url]http://www.photomacrography.net/forum/viewforum.php?f=29]Frequently Asked Questions forum[/url].
Code: Select all
[url]https://en.wikipedia.org/wiki/Lens_(optics)[/url]
Code: Select all
[url]https://en.wikipedia.org/wiki/Lens_%28optics%29[/url]
To clean up the visual appearance, you can jump through the additional hoop of using the original form as replacement text for the URL-encoded form:
Code: Select all
[url=https://en.wikipedia.org/wiki/Lens_%28optics%29]https://en.wikipedia.org/wiki/Lens_(optics)[/url]
(But of course if you mess up the use of that equal sign, the whole post will again print as blank!)
The erroneous blankness also shows up if you press the Preview button, so this is another good argument for always previewing your posts before submitting them.
