<?php
require('config/config.inc.php');
$sql = "SELECT id, name, Status, Strasse, Telefon, ProblemBeschreibung, Datum FROM probleme WHERE id = 1 OR id > 1";
$result = mysqli_query($db, $sql);
if(mysqli_num_rows($result) > 0) {
// Ausgabe der Daten in einer row
echo '<table class="bordered"><thead>';
echo '<tr>';
echo '<th style="display: none;">ID</th>';
echo '<th>Name</th>';
echo '<th>Status</th>';
echo '<th>Straße</th>';
echo '<th>Telefon</th>';
echo '<th>Problembeschreibung</th>';
echo '<th>Eintragsdatum</th>';
echo '<th width="36"></th>';
echo '</tr></thead>';
echo '<tbody>';
while($adr = mysqli_fetch_assoc($result)) {
echo "<tr>
<td>" . $adr['name'] . "</td>
<td>" . $adr['Status'] . "</td>
<td>" . $adr['Strasse'] . "</td>
<td>" . $adr['Telefon'] . "</td>
<td>" . $adr['ProblemBeschreibung'] . "</td>
<td>" . $adr['Datum'] . "</td>
<td>
<div id=\"test\">
<div id=\"div1\"><form action='edit.php' method='GET'>
<input type='hidden' name='id' value='" .htmlspecialchars($adr['id'], ENT_COMPAT, 'UTF-8') . "'/>
<input type='hidden' name='name' value='".htmlspecialchars($adr['name'], ENT_COMPAT, 'UTF-8')."'/>

</form></div>
<div id=\"div2\">
<form action='delete.php' method='POST'>
<input type='hidden' name='id' value='" . htmlspecialchars($adr['id'], ENT_COMPAT, 'UTF-8') . "'/>
<input type='image' src='delete.png' height='16' width='16' name='delete' value='Löschen' onClick=\"self.location.href='delete.php?\">
</form></div>
</div>
</td>
</tr>\n";
}
echo "</tbody></table>";
} else {
echo "0 Einträge gefunden<br>Es konnten keine Einträge in der Datenbank gefunden werden.";
}
mysqli_close($db);
?>
My edit.php
<table class="bordered">
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>Status</th>
<th>Strasse</th>
<th>Telefon</th>
<th>Problembeschreibung</th>
<th>Eintragsdatum</th>
</tr>
</thead>
<?php
include('config.inc.php');
if(isset($_GET['id'])){
$id = $_GET['id'];
} else {
die('Bitte eine ?id übergeben');
}
$statement = $pdo->prepare("SELECT * FROM probleme WHERE id = ?");
$statement->execute(array($id));
while($row = $statement->fetch()){
echo "<tr>
<form method='post' action='edit1.php'>
<td><input name='id' type='text' value='".$id."'</input></td>
<td><input name='name' type='text' value='" .$row['name']."'</input></td>
<td>
<select name='Status'>
<option>".$row['Status']."</option>
<option>FINISHED</option>
</select>
</td>
<td><input name='Strasse' type='text' value='".$row['Strasse']."'</input></td>
<td><input name='Telefon' type='number' value='".$row['Telefon']."'</input></td>
<td><input name='ProblemBeschreibung' type='text' value='".$row['ProblemBeschreibung']."'</input></td>
<td>".$row['Datum']."</td>
</tr>
</table>";
echo "
<input type='submit' value='Absenden' />
</form>";
}
?>
If I change GET to POST it doesnt work too.
