php获得数据库的字段名 php获取数据库用户id

如何用ASP或PHP自动生成数据库字段名function add($name, $type, $size, $defaultvaluehttps://www.04ip.com/post/= '', $options = '', $title = '', $note = '', $formtype = '', $inputtool = '', $inputlimit = '', $enablehtml = 1, $enablelist = 1, $enablesearch = 0)
{
if(!in_array($type, $this-fieldtypes) || $this-exists($name)) return FALSE;
$size = intval($size);
$fieldsize = $type == 'varchar' ? min($size, 255) : ($type == 'int' ? min($size, 10) : 0);
$fieldtype = strtoupper($type);
if($fieldsize) $fieldtype .= "( $fieldsize )";
$this-db-query("ALTER TABLE $this-table ADD $name $fieldtype NOT NULL");
$this-db-query("INSERT INTO ".TABLE_FIELD."(tablename,name,type,size,defaultvalue,options,title,note,formtype,inputtool,inputlimit,enablehtml,enablelist,enablesearch) VALUES('$this-table','$name','$type','$size','$defaultvalue','$options','$title','$note','$formtype','$inputtool','$inputlimit','$enablehtml','$enablelist','$enablesearch')");
$result = $this-db-affected_rows();
$this-cache();
return $result;
}
function edit($fieldid, $type, $size, $defaultvaluehttps://www.04ip.com/post/= '', $options = '', $title = '', $note = '', $formtype = '', $inputtool = '', $inputlimit = '', $enablehtml = 1, $enablelist = 1, $enablesearch = 0)
{
if(!in_array($type, $this-fieldtypes)) return FALSE;
$fieldid = intval($fieldid);
$field = $this-get_info($fieldid);
$name = $field['name'];
$size = intval($size);
$fieldsize = $type == 'varchar' ? min($size, 255) : ($type == 'int' ? min($size, 10) : 0);
$fieldtype = strtoupper($type);
if($fieldsize) $fieldtype .= "( $fieldsize )";
$this-db-query("ALTER TABLE `$this-table` CHANGE `$name` `$name` $fieldtype NOT NULL");
$this-db-query("UPDATE ".TABLE_FIELD." SET title='$title',note='$note',type='$type',size='$size',defaultvalue='https://www.04ip.com/post/$defaultvalue',options='$options',formtype='$formtype',inputtool='$inputtool',inputlimit='$inputlimit',enablehtml='$enablehtml',enablelist='$enablelist',enablesearch='$enablesearch' WHERE fieldid=$fieldid");
$result = $this-db-affected_rows();
$this-cache();
return $result;
}
function delete($fieldid)
{
$fieldid = intval($fieldid);
$r = $this-db-get_one("SELECT name FROM ".TABLE_FIELD." WHERE fieldid=$fieldid");
if(!$r) return FALSE;
$name = $r['name'];
【php获得数据库的字段名 php获取数据库用户id】$this-db-query("ALTER TABLE $this-table DROP $name");
$this-db-query("DELETE FROM ".TABLE_FIELD." WHERE fieldid=$fieldid");
$result = $this-db-affected_rows();
$this-cache();
return $result;
}
db数据库类去下个phpcms里面的就是上面的是自定义字段的操作函数
PHP中怎样获取字段的名称?$con = mysql_connect('localhost','root','');
if($con){
mysql_query('use yatibang');
mysql_query('set names utf8');
}else{
echo "数据连接失败";
}
$sql = "desc app_category";
$res = mysql_query($sql);
$row = $rows = array();
while( $row = mysql_fetch_assoc($res)){
$rows[] = $row['Field'];
}
var_dump($rows);
返回结果如下php获得数据库的字段名:
php读取mysql表用户名和php获取mysql表字段名称和字段信息有三种方法 。这三种方法分别为:mysql_fetch_field方法、desc方法和SHOWFULLFIELDS方法 。php查看mysql的用户名和密码的方法,打开Navicat并找到mysql,打开mysql数据库连接,单击工具栏中的用户选项即可查看 。
php调用数据库字段这个先连接数据库,然后调用,代码如下:
$dbhost = 'localhost:3306';// mysql服务器主机地址
$dbuser = 'root';// mysql用户名
$dbpass = '123456';// mysql用户名密码
$conn = mysqli_connect($dbhost, $dbuser, $dbpass);
if(! $conn ){
die('Could not connect: ' . mysqli_error());
}
echo '数据库连接成功!';mysqli_close($conn);
$sql=mysql_query("select *from wx_agent_orders where id=1");
$row=mysql_query($conn,$sql);
while($r=mysql_fetch_array($row)){
echo $r['sendcontent']
}
这是最基础的php获取mysql方法了,希望采纳
