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
)
