Question

<html>
<form method="POST" action="insertlines.php">
<textarea name="url" rows="10" ></textarea>
<input type="submit" name="submit" value="Enter">
</form>
</html>

如何将textarea的每一行都放入MySQL行？

我想要的是我输入的内容：

John
Peter
Steven

在textarea中，我希望它们在我的数据库中各有不同的ID。

Answer 1

你必须解析文本，寻找“输入”字符：

<?php
if(isset($_POST['url'])){
    if(strpos($_POST['url'], "\n")){
        $entries = explode("\n", $_POST['url']);
    } else {
        $entries = array($_POST['url']);
    }
    // connect to DB here
    // then iterate over entries
    foreach($entries as $e){
        // build some type of Prepared Statement to protect from SQL Injection
        $q = "INSERT INTO table (col1) VALUES (?)";
        // bind $e to statements
        // Execute SQL statements
    }
    // close DB connection
}
?>

试试这个：

$textarea=$_POST['url']
$sql = 'INSERT INTO YourTable(field1,field2,name) VALUES';
foreach(explode("\n", $textarea) as $row) {
$sql.='("field1","field2",.'$row'.)';
} 
$conn->query($sql)
