[英]Array from database to editable form
I want to make a form where I can edit information from an array I get from my database.我想制作一个表单,我可以在其中编辑从我的数据库中获取的数组中的信息。 And then put them in a form with strings so I can edit the values of each category from the database and then send the changed information to the database.
然后将它们放在带有字符串的表单中,以便我可以编辑数据库中每个类别的值,然后将更改后的信息发送到数据库。 When I use this command
当我使用这个命令时
$db = new PDO('mysql:host=mariadb.spectrogon.local;dbname=gitter;charset=utf8', 'gitter_in', 'gitter_in');
$sql = "call hämta_artikel_info('715.702.930')";
$result = $db->query($sql);
$printable = $result->fetchAll();
print_r($printable);
I get the following array back我得到以下数组
(
[artikel_nr] => 715.702.930
[0] => 715.702.930
[points] => 50x50 5
[1] => 50x50 5
[points2] => 50x50 5
[2] => 50x50 5
[scale] => 1 + 0.75
[3] => 1 + 0.75
[energy] => 70
[4] => 70
[value] => 5.000
[5] => 5.000
[nollan] =>
[6] =>
[approved_from] =>
[7] =>
[approved_to] =>
[8] =>
)
Now I would like to put all the info I've got from this array and put it in a form.现在我想把我从这个数组中得到的所有信息放在一个表单中。 Then I would be able to edit that information
然后我就可以编辑该信息
The following SQL: " call hämta_artikel_info(715.702.930)"
as far as I know should be a select
procedure以下 SQL:
" call hämta_artikel_info(715.702.930)"
据我所知应该是一个select
过程
My full code atm.我的完整代码自动取款机。
<?php
echo "test";
error_reporting(E_All);
error_reporting(E_ERROR | E_WARNING | E_PARSE);
$db = mysqli_connect('mysql:host=mariadb.spectrogon.local;dbname=gitter;charset=utf8', 'gitter_in', 'gitter_in');
$connection = new Connection;
$db = $connection->openConnection();
$stmt = $db->prepare("call hämta_artikel_info('715.702.930')");
$stmt->execute();
print_r($stmt);
echo "
while($results = $stmt->fetch()){
<form name='form' method='post' action=''>
<tbody>
<tr>
<td><input type='text' name='id' readonly class='form-control-plaintext' value=" . $results['artikel_nr'] ."></td>
<td><input type='submit' name='update' value='Update' class='form-control'></td>";
if(isset($_POST['update']))
{
$var= $_POST['var'];
if(empty($var){
echo"variable is empty ";
}
else {
$stmt = $db->prepare("UPDATE table_name SET col_name='" .$var. "'");
}
$stmt->execute();
@header("Location: stackoverflow.php");
}
}
?>
Keep in mind that I'm very new to programming so would really appreciate detailed explanations.请记住,我对编程非常陌生,因此非常感谢详细的解释。
put foreach loop like 像这样放foreach循环
foreach($printable as $data) {
echo $printabel->username;
}
define every thing alone $printable->your database fields here;
在这里定义每件事
$printable->your database fields here;
$result = $stmt->get_result();
echo "<form name='form' method='post' action =''>
<tbody>";
while ($row = $result->fetch_assoc()) {?>
<td>
<input type='text' name='id' readonly class='form-control-plaintext' value="<?php echo $row['artikel_nr'];?>">
</td>
<?php}
echo "<td>
<input type='submit' name='update' value='Update' class='form-control'>
</td>
</tbody>
</form>";
