Question

我有一长串需要插入数据库的表单值。有没有一种有效的方法将所有这些值插入到我的数据库中的单独列中？

这是我的代码：

PHP：

// I've removed most of them to simplify demonstration
$title = isset($_POST['title']) ? $_POST['title'] : "";
$name = isset($_POST['name']) ? $_POST['name'] : "";
$description = isset($_POST['description']) ? $_POST['description'] : "";
$how_hear = isset($_POST['how_hear']) ? $_POST['how_hear'] : "";

// I have to do this for every single form element:
if (!empty($title)) {
    DB::query('INSERT INTO `table` (`title`) VALUES (?);', array($title));
}

Answer 1

$usrData = array(
    "user" => "hello",
    "pass" => "pass1",
    "mail" => "test@email.com"
);

$cols = "";
$vals = "";
foreach($usrData as $col => $val) {
    $col = mysql_real_escape_string($col);
    $val = mysql_real_escape_string($val);

    $cols.= "`{$col}`, ";
    $vals.= "'{$val}', ";
}
$query = "INSERT INTO `myTable` (". rtrim($cols, ", ") .") VALUES (". rtrim($vals, ", ") .");";   
mysql_query($query);

Answer 2

尝试这样

$usrData = array(
    array(
        "user" => "hello",
        "pass" => "pass1",
        "mail" => "test@email.com"
    ),
    array(
        "user" => "user2",
        "pass" => "pass2",
        "mail" => "user2@email.com"
    )
);

$cols = "";
$bindQuery = "";
$i = 0;
foreach($usrData as $udata) {
    $vals = "";
    foreach($udata as $col => $val){    
        $col = mysql_real_escape_string($col);
        $val = mysql_real_escape_string($val);

        $vals.= "'{$val}', ";

        if($i == 0)
            $cols.= "`{$col}`, ";       
    }
    $bindQuery.= "(" . rtrim($vals, ", ") . "), ";
    $i++;
}
echo $query = "INSERT INTO `myTable` (". rtrim($cols, ", ") .") VALUES ". rtrim($bindQuery, ", ") .";";   
mysql_query($query);

Answer 3

假设

数据库字段名称和表单字段名称不相同。
应将所有数据插入数据库中的同一记录中。
即使一个或多个字段为空，也应将所有数据输入数据库。

示例发布数据

下面的代码在输出示例查询时使用以下示例数据（就好像它是通过POST方法从站点发送的）。

$_POST["title"] = "Mr.";
$_POST["name"] = "Joe Bloggs";
$_POST["description"] = "Whatever it is this field is for, presumably some text...";
$_POST["how_hear"] = "google / search engine";

代码

$column_names = array( 
// Structure:           db-field-name   => form-field-name                        
                        "title"         => "title",
                        "customer_name" => "name",          // Example: Database field name would be "customer_name" and the form field name would be "name"
                        "content"       => "description",
                        "pointer"       => "how_hear"
                    ); 

$insert_columns = "";
$insert_values  = "";

foreach($column_names as $db_name=>$ws_name){ // Loop through fields specified in $column_names

    $value           = empty($_POST[$ws_name]) ? '' : $_POST[$ws_name];

    $insert_columns .= ", `".$db_name."`"; // Backticks to denote field names
    $insert_values  .= ", '".$value."'";   // Single quotes to denote values

}

// Generate the query
// substr function removes ", " from start of strings
$insert_query = "INSERT INTO `table_name` (".substr($insert_columns, 2).") VALUES (".substr($insert_values, 2).")";



echo $insert_query; // Show example output
// INSERT INTO `table_name` (`title`, `customer_name`, `content`, `pointer`) VALUES ('Mr.', 'Joe Bloggs', 'Whatever it is this field is for, presumably some text...', 'google / search engine')

快速积分

速记if声明：

$value = empty($_POST[$ws_name]) ? '' : $_POST[$ws_name];

// Is equivalent to:

if( empty($_POST[$ws_name]) ) {
    $value = "";
}
else {
    $value = $_POST[$ws_name];
}

上述代码没有对清理输入做任何事情，所以不要忘记清理数据等。
您可以根据需要向$column_names数组添加任意数量的字段，且顺序不相关。
我已使用echo来显示代码生成的查询作为示例。您显然不会这样做...而是将查询$insert_query传递给您的数据库连接。类似的东西：
```
DB::query($insert_query);
```
当然，这可能（或者更确切地说：）会根据您连接数据库的方式而改变...
