valentina_field_flags()
Declaration
string valentina_field_flags ( resource result, int field_offset )
Parameters
Name | Description | |
---|---|---|
result | The result resource that is being evaluated. This result comes from a call to val_query(). | |
field_offset | The numerical field offset. The field_offset starts at 0. If field_offset does not exist, an error of level E_WARNING is also issued. |
Description
Returns the field flags of the specified field. The flags are reported as a single word per flag separated by a single space, so that you can split the returned value using explode().
Return Values
Returns a string of flags associated with the result, or FALSE on failure.
The following flags are reported, if your version of VServer is current enough to support them: “METHOD”, “not_null”, “auto_increment”, “unique_key” and “INDEXED”.
Examples
Example 1.
<?php $result = valentina_query("SELECT id,email FROM people WHERE id = '42'"); if (!$result) { echo 'Could not run query: ' . valentina_error(); exit; } $flags = valentina_field_flags($result, 0); echo $flags; print_r(explode(' ', $flags)); ?>
The above example will output something similar to:
not_null primary_key auto_increment Array ( [0] => not_null [1] => auto_increment [2] => unique_key )
