推荐答案
尝试以下方法:
<?php
require('includes/config.php');
function get_info($dbh, $name)
{
$sql = $dbh->prepare("SELECT * FROM info WHERE name = :name");
$sql->setFetchMode(PDO::FETCH_ASSOC);
$sql->execute([':name' => $name]);
if ($row = $sql->fetch()) {
return $row;
}
return false;
}
?>
<table border="0">
<tr COLSPAN=2 BGCOLOR="#6D8FFF">
<td>ID</td>
<td>Name</td>
<td>Age</td>
</tr>
<?php
if (isset($_POST['name1'])) {
if ($row = get_info($dbh, $_POST['name1'])) {
echo "<tr>" .
"<td>" . $row["id"] . "</td>" .
"<td>" . $row["name"] . "</td>" .
"<td>" . $row["age"] . "</td>" .
"</tr>";
} else {
echo "don't exist records for list on the table";
}
}
?>
</table>
