1)我自己遇到的实际情况 是sessions表有问题 ,删掉 重新导一个空的好表就可以了
如何知道sessions有问题呢?
开启devel模块的在最下面显示sql执行语句的功能
看看哪个表执行的时间太长了,超过几千秒
肯定它有问题
(我发现了是sessions表有个insert语句 2千多秒)此时删掉
这个表 重建一个空的好表就可以了,以前也遇到其它出现问题的情况,也是
同样的方法解决的
2)我自己遇到第二个情况 Warning: MySQL server has gone away query: INSERT INTO watchdog
同时发现红色警告 Warning: MySQL server has gone away query: INSERT INTO cache_l10n_update

1)hook_validate
2)hook_nodeapi时验证
2)下面的方法是比较好的

function mymodule_form_alter(&$form, &$form_state, $form_id) {
	switch($form_id) {
		case 'artist_node_form':
			$form['#after_build'][] = 'mymodule_custom_after_build';
			break;
	}
}

function mymodule_custom_after_build($form, &$form_state) {
	$form['#validate'][] = 'mymodule_custom_validation';					
	
	return($form);
}

function mymodule_custom_validation($form, &$form_state) {
	//My custom validations went here.
}

　　在普通情况下，当用户提交节点表单后会被重定向到对应的节点页面，如果在 URL 中传入了 ?destination=path/xxx 这样的参数，提交表单后用户就会被重定向到 destination 设置的页面。

　　除此之外，开发人员还可以通过为节点表单设置重定向属性，来控制表单提交后的重定向路径。

　　下面的代码通过应用 hook_form_alter()，判断当表单ID为"story_node_form"时，设置表单的重定向属性（#redirect）
