In-Depth Information
By default, the lower drop-down menus are set to
Save
(so that we make changes
to this row) and
Go
back
to
previous
page
(so that we can continue editing another
row on the previous results page). We might want to stay on the current page after
clicking on
Go
—in order to save and then continue editing—we can choose
Go
back
to
this
page
. If we want to insert yet another new row after saving the current row,
we just have to choose
Insert
another
new
row
before saving. The
Insert
as
new
row
choice (below the
Save
choice) is explained in the
Duplicating
rows
of
data
section later
in this chapter.
Moving to next field with the tab key
People who prefer to use the keyboard can use the
Tab
key to go to the next field.
Normally, the cursor goes from left to right and from top to bottom, so it would
travel into the fields in the
Function
column (more on this in a moment). However,
to ease data navigation in phpMyAdmin, the normal order of navigation has been
altered. The
Tab
key first goes through each field in the
Value
column, and then
through each one in the
Function
column.
Moving with arrows
Another way of moving between fields is with the
Ctrl
+
arrow
keys. This method
might be easier than using the
Tab
key when many fields are on screen. For this to
work, the
$cfg['CtrlArrowsMoving']
parameter must be set to
true
, which is the
default value.
In some situations, this technique cannot be used for moving between
fields. For example, the Google Chrome browser does not support
Ctrl
+
arrow
. Also, on Mac OS X 10.5 with Spaces enabled,
Ctrl
+
arrow
is the default shortcut to switch between virtual desktops.
Handling NULL values
If the table's structure permits a
NULL
value inside a column, a small checkbox
appears in the column's
Null
column. Selecting this puts a
NULL
value in the column.
Whenever data is typed into this column's
Value
, the
Null
checkbox is cleared
automatically. (This is possible in JavaScript-enabled browsers.)
