标签: php mysql insert

我有以下功能:

function insert($database, $table, $data_array)
{
# Connect to MySQL server and select database
$mysql_connect = connect_to_database();
mysql_select_db ($database, $mysql_connect);

# Create column and data values for SQL command
foreach ($data_array as $key => $value) 
    {
    $tmp_col[] = $key;
    $tmp_dat[] = "'$value'";
    }
 $columns = join(",", $tmp_col);
 $data = join(",", $tmp_dat);

# Create and execute SQL command
$sql = "INSERT INTO ".$table."(".$columns.")VALUES(". $data.");";
$result = mysql_query($sql, $mysql_connect);

# Report SQL error, if one occured, otherwise return result
if(mysql_error($mysql_connect))
    {
    echo "MySQL Update Error: ".mysql_error($mysql_connect);
    $result = "";
    }
else
    {
    return $result;
    }
}

php中的值如下:

$content_table = "p_content";
$insert_array['title'] = $title;
    $insert_array['content'] = $content;
$insert_array['url'] = $get_source;
$insert_array['video'] = $video;
$insert_array['date'] = $date;
insert(DATABASE, $content_table, $insert_array);

所有这些的结果添加了一行id(key,autoimcrement),url和date。标题,内容和视频都是空白的。如果我回显标题我得到正确的结果,如果我var_dump标题我得到字符串(15)" blablablabla",再次正确。

现在如果我设置$ title =" asdf&#34 ;;它被正确插入。内容和视频也是如此。

表格结构

id int(8)unsigned NO PRI NULL auto_increment

title varchar(1000)YES NULL

内容longtext YES NULL

video varchar(3000)YES NULL

url varchar(300)YES NULL

日期日期YES NULL

尝试:

function insert($database, $table, $data_array)
{
    # Connect to MySQL server and select database
    $mysql_connect = connect_to_database();
    mysql_select_db($database, $mysql_connect);

    $cols = array();
    $vals = array();
    foreach ($data_array as $key => $value) {
        $cols[] = "`" . $key . "`";
        if (is_int($value) || is_float($value)) {
            $vals[] = $value;
        } else {
            $vals[] = "'" . mysql_real_escape_string($value) . "'";
        }
    }

    $sql = "INSERT INTO " . $table
         . ' (' . implode(', ', $cols) . ') '
         . 'VALUES (' . implode(', ', $vals) . ')';

    $result = mysql_query($sql, $mysql_connect);

    # Report SQL error, if one occured, otherwise return result
    if(mysql_error($mysql_connect)) {
        echo "MySQL Update Error: " . mysql_error($mysql_connect);
        $result = ""; // FIXME should probably return false here
    } else {
        return $result;
    }
}

尝试在变量中添加引号。 :-)原因是你将MYSQL列类型设置为VARCHAR。插入数据需要用引号括住插入内容。

B.T.W。如果这是新代码,我建议切换到MYSQLI或PDO库。
