插入文本並將其放入MYSQL數據庫之前分離

Question

我想創建一個函數，通過一個客戶端可以通過textarea（即複製和粘貼）上傳代碼代碼，並且一旦表單提交，代碼將提取每個代碼並將其放置在數據庫中擁有自己的id。

代碼示例將

GBVVVVVVV

HGBBBBBBB

Answer 1

你可以這樣做：

$vouchers = explode("\n", $textfield); 

這使變量$文本框的每行到一個數組名爲$券。

然後你可以通過數組中的所有物品，像這樣的循環：

foreach ($vouchers as &$value) { 
    // put your mysql insert here 
} 

Answer 2

你會讓一個SQL語句，像這樣：

// Replace "<table name>" with the name of your table. 
// This sets up the first part of the SQL statement. This should look very 
// familiar if you have used any flavor of SQL. 
$query = 'INSERT INTO <table name> VALUES '; 
$is_first = true; 

// Loop through each line. 
// We assume '\n' is the line separator. 
// You will need to replace "<textarea name>" with the proper value. 
foreach (explode('\n', $_POST['<textarea name>']) as &$voucher) { 
    // This determines whether or not we need a comma to separate multiple 
    // records. See note below. 
    if ($is_first) $is_first = false; else $query .= ', '; 
    // This can be unfamiliar to some who are somewhat familiar with SQL. You can 
    // insert more than one record with just one query. 
    // Note that we escape the $voucher variable to prevent SQL injections. 
    $query .= '(' . mysql_real_escape($voucher) . ')'; 
} 

然後，通過PHP將它像正常的SQL語句一樣發送出去。請注意，這假定您正在使用post方法。此外，這可能會有錯誤。我還沒有測試過它，但它肯定會引導你朝着正確的方向發展。
