$arr = array( array ( array( 'CAR_TIR', 'Tires', 100 ),
array( 'CAR_OIL', 'Oil', 10 ),
array( 'CAR_SPK', 'Spark Plugs', 4 )
),
array ( array( 'VAN_TIR', 'Tires', 120 ),
array( 'VAN_OIL', 'Oil', 12 ),
array( 'VAN_SPK', 'Spark Plugs', 5 )
),
array ( array( 'TRK_TIR', 'Tires', 150 ),
array( 'TRK_OIL', 'Oil', 15 ),
array( 'TRK_SPK', 'Spark Plugs', 6 )
)
);
function recarray($array)
{
foreach($array as $key=>$value)
{
if(is_array($value))
{
RecArray($value);
}
else
{
echo "key = $key value …我有这个简单的表单提交它将被重定向到submit.php,如果有错误,它会显示错误消息submit.php.现在我想要的是将错误消息显示回表单页面.
