/**
27
 * Use this ViewHelper to provide 'create new record' links.
28
 * The ViewHelper will pass the command to FormEngine.
29
 *
30
 * The table argument is mandatory, it decides what record is to be created.
31
 *
32
 * The pid argument will put the new record on this page, if ``0`` given it will
33
 * be placed to the root page.
34
 *
35
 * The uid argument accepts only negative values. If this is given, the new
36
 * record will be placed (by sorting field) behind the record with the uid.
37
 * It will end up on the same pid as this given record, so the pid must not
38
 * be given explicitly by pid argument.
39
 *
40
 * An exception will be thrown, if both uid and pid are given.
41
 * An exception will be thrown, if the uid argument is not a negative integer.
42
 *
43
 * To edit records, use the :ref:`<be:uri.editRecord> <typo3-backend-uri-editrecord>`.
44
 *
45
 * Examples
46
 * ========
47
 *
48
 * Uri to create a new record of a_table after record 17 on the same pid::
49
 *
50
 *    <be:uri.newRecord table="a_table" returnUrl="foo/bar" uid="-17"/>
51
 *
52
 * ``/typo3/index.php?route=/record/edit&edit[a_table][-17]=new&returnUrl=foo/bar``
53
 *
54
 * Uri to create a new record of a_table on root page::
55
 *
56
 *    <be:uri.newRecord table="a_table" returnUrl="foo/bar""/>
57
 *
58
 * ``/typo3/index.php?route=/record/edit&edit[a_table][]=new&returnUrl=foo/bar``
59
 *
60
 * Uri to create a new record of a_table on page 17::
61
 *
62
 *    <be:uri.newRecord table="a_table" returnUrl="foo/bar" pid="17"/>
63
 *
64
 * ``/typo3/index.php?route=/record/edit&edit[a_table][17]=new&returnUrl=foo/bar``
65
 *
66
 * Uri to create a new record of a_table on page 17 with a default value::
67
 *
68
 *    <be:uri.newRecord table="a_table" returnUrl="foo/bar" pid="17" defaultValues="{a_table: {a_field: 'value'}}"/>
