Question

我想在数据库返回的每一行的底部添加一个按钮，但无法理解我将如何执行此操作。该按钮应该是一个简单的“提交”样式按钮。

include("shared.php");

class TableRows extends RecursiveIteratorIterator { 

    function __construct($it) { 

        //going through each field - lowest level
        parent::__construct($it, self::LEAVES_ONLY); 
    }

    function current() {
        return parent::key(). ": " . parent::current(). "</td>" . "<br/>";
    }

    //goes through, the first row returned
    function beginChildren() { 
        echo "  " . "<br/>"; 
    } 

    //last one
    function endChildren() { 
        echo "</tr>" . "<br/>";
    } 
} 

$database = new PDO("DATABASE CONNECTION");
$database->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$query = $database->prepare("SELECT * FROM Books"); 
$query->execute();

// set the resulting array to associative
$rows = $query->setFetchMode(PDO::FETCH_ASSOC); 

foreach(new TableRows(new RecursiveArrayIterator($query->fetchAll())) as $k=>$v) { 
    echo $v;
}

Answer 1

只需在倒数第二行的回声末尾添加按钮：

echo $v . "<button>submit</button>";

Answer 2

这是你在找什么？

foreach(new TableRows(new RecursiveArrayIterator($query->fetchAll())) as $k=>$v) {
    echo $v . '<button type="button">Submit</button>';
}

Answer 3

添加

echo $v . "<button type='submit' value='Submit'>Submit</button>" in your foreach.

使用PHP向数据库返回的每一行添加按钮
