我试图找出如何在一个表单中的单个文本框中输入多个单词输入,每个单词用逗号(,)分隔,然后根据逗号分隔单词,并将每个单词作为单独的记录插入db
我想到的是接受输入
然后使用php的explode函数分离出单词,并存储在db中,但我不知道如何在db中存储。

我知道一堆mysql_ *函数的答案会进来,所以不好添加准备好的查询路径。
这不是完美的,但你会明白这个想法
// Get the array of words
$words = explode( ',', $formname );
// Create an array of :word1, :word2, :word3, etc for use in binding
foreach( range( 1, count( $words ) ) as $wordnumber ) {
$bind[] = ':word'.$wordnumber;
}
// Create the sql query
$sql = sprintf( "insert into table ( word ) values ( %s )", implode( '),(', $bind ) );
// Prepare the query
$stmnt = $pdo->prepare( $sql );
// Bind each word
foreach( $words as $k => $word ) {
$stmnt->bindValue( ":word" . ++$k, $word );
}
// Execute
$stmnt->execute();

你也可以用PDO做到这一点:
<?php
//Connect safely to your database
try {
$db = new PDO("mysql:host=localhost;dbname=test", 'root', 'password');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE,PDO::FETCH_ASSOC);
} catch (PDOException $e) {
die('Cannot connect to mySQL server. Details:'.$e->getMessage());
}
if ($_SERVER['REQUEST_METHOD']=='POST' && !empty($_POST['words'])) {
$sql = "INSERT INTO words_table (word) VALUES (:word)";
$stmt = $db->prepare($sql);
$stmt->bindParam(':word', $word);
foreach (explode(',', $_POST['words']) as $word) {
$word = trim($word);
if (empty($word)) {
continue;
}
$stmt->execute();
}
}
//Your form
?>
<h1>Words</h1>
<form method="POST" action="">
<input type="text" name="words"/>
<input type="submit" name="submit" value="Submit"/>
</form>

如果您需要将单词封装在引号中,这应该可以解决问题:
<?php
$myString='sometext,someothertext,and something else';
$query="insert into table1 (columnName) values (('".str_replace(',',"'),('",$myString)."'))";
echo $query;
?>
输出:
insert into table1 (columnName) values (('sometext'),('someothertext'),('and something else'))
这将根据mysql insert multiple values syntax正确插入多条记录。

$str = $_POST['words'];
$piece = explode(',',$str);
foreach($piece as $substr){
mysql_query("INSERT INTO test (words) VALUES ('".$substr."');";
}
