How can I pass USER_ID of the tag < a >
for a Javascript function Javascript that set a hidden field?
I tried the Javascript function showConfirm()
, but the hidden field isn't being filled. It stays null... I think the onClick attribute, of the field deleteid
, is wrote wrong.
I want fill this field by javascript. How can I?
The message of error says
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near '' at line 1
probably because the hidden field "id_action"
isn't receiving datas of the function.
Whatever, the main problem is set the function showConfirm
by paramters 'show', $row['id']
for the hidden field id_action
.
<script>
function showConfirm (action, delID) {
if (action == 'show') {
document.confirm.id_action.value = delID;
}
}
</script>
<tbody>
<?php
if (!empty($_POST)) {
if (isset($_POST['id_action'])) {
$del_id = $_POST['id_action'];
$delUser = new User;
$delUser->deletarUsuario($del_id);
unset($delUser);
}
}
$listUser = new User;
$result = $listUser->listarUsers();
if (is_array($result)) {
foreach ($result as $row) {
echo "
<tr>
<td align='right'>" . $row['id'] . "</td>
<td>". $row['name'] . " ".$row['sobrename']."</td>
<td>" . $row['email'] . "</td>
<td>" . $row['login'] . "</td>
<td>
<a data-toggle='modal' id='deleteid' data-target='#modal_delUser' onclick=\"showConfirm('show'," . $row['id'] . ")\">
Remove
</a>
</td>
</tr>";
}
}
unset($listUser);
?>
</tbody>

Here the SQL that I am generating from the query
public function deletarUsuario($id) {
$del_id = $this->db->real_escape_string(trim($id));
if ($update = $this->db->query("DELETE FROM usuario WHERE id = $del_id")) {
if ($this->db->affected_rows) {
echo "<div><p>Deleted user!</p></div>";
}
else {
echo "<div><p>Failed to delete user.</p></div>";
}
}
else {
echo "<div><p>". $this->db->error."</p></div>";
echo "<script>$('#modal_erroBD').modal('show');</script>";
}
}
