Joomla! Menus by default show their titles. Normally this is not a desireable behaviour, particularly when there is only one menu and the "Main Menu" title is rather pointless.
To hide the menu title, go into Module Manager, click the name of your menu under the Module Name column, then in the Details section click No for Show Title.
I recently had trouble adding a foreign key on a MySQL database.
ERROR 1005 (HY000): Can't create table '.\test\b.frm' (errno: 150)
After much searching I discovered that the problem was that the columnbeing references needed to be indexed.
So then adding a foreign key, make sure;
The concept of NULL in SQL, including MySQL, is a little hard to get at first, so the NULL keyword is tough to use as well.
This blog post helps to clarify it.
This is a simple technique to extract the filename extension from a filename. It could easily be adapted to extract the filename from a path or a query string from a URL by changing the first parameter of the explode() function.
$extension = end(explode('.', $filename)); |
Sometimes the text in a form field is put there primarily for the purpose of being copied to the clipboard.
In these cases a little JavaScript will smooth the process, selecting the full contents of the field on the first click.
Place the following script in the
section of your page:1 2 3 4 5 | <script type="text/JavaScript"> function highlight(field) { field.focus(); field.select(); }</script> |
Then place onClick='highlight(this);' as an attribute to any field you want treated this way:
1 | <input type="text" name="myfield" size="20" value="mytext" onClick='highlight(this);'> |
