我有一个来自 MySQL 的语言表,在数据库中有一行“启用”,其值为 1 或 0。1 表示启用的语言,0 表示禁用。我想用我的 html/php 表中的复选框更改这些值。
我遇到的问题是输入名称,因为它们是来自数据库的变量+选中复选框的值。
我的代码如下所示:
require_once ('../mysqli_connect.php'); // Connect to the db.
if(isset($_POST['submit']))
{
$lang_q="SELECT * FROM language";
$lang_r = @mysqli_query ($dbc, $lang_q); // Run the query.
while($lang_row = mysqli_fetch_array($lang_r, MYSQLI_ASSOC)){
$lang_code2[]=$lang_row['lang_code'];
$language[]=$lang_row['language'];
$langid2[]=$lang_row['lang_id'];
$lang_active2[]=$lang_row['enabled'];
}
$language2=$_POST[$language];
$lang_active=$_POST[$lang_active2];
$langid=$_POST[$langid2];
$m="test";
if(isset($language2)){
foreach ($lang_active as $key => $value) {
$value="1";
}
//$lang_active='1';
$m.="-uspjeh";
}
$q="UPDATE language SET enabled='$lang_active' where lang_id='$langid' ";
$r = @mysqli_query($dbc, $q); // Run the query.
if($r){
$success=true;
require_once ('includes/login_functions.inc.php');
$url = absolute_url();
$url = absolute_url("language-manager.php?success=update");
header("Location: $url");
$m.="-da";
}
else{
$s ="<br />GREŠKA UPDATE";
echo mysqli_error($r);
$m.="-ne";
}
}
$page_title = PAGE_TITLE84;
include_once('includes/header.php');?>
<?php
$lang_q="SELECT * FROM language";
$lang_r = @mysqli_query ($dbc, $lang_q); // Run the query.
echo $m.'-dadda';
echo '
<form action="language-manager.php" method="POST" name="language-manager">
<table class="languages">
<tr>
<td>'.LANGUAGE_R.'</td>
<td>'.ACTIVE_R.'</td>
</tr>
';
while($lang_row = mysqli_fetch_array($lang_r, MYSQLI_ASSOC)){
$lang_code2=$lang_row['lang_code'];
$language=$lang_row['language'];
$lang_active=$lang_row['enabled'];
$langid=$lang_row['lang_id'];
echo '<tr>
<td class="lang"><img src="../flags/'.$lang_code2.'.png" />'.$language.'</td>
<td>
<input type="checkbox" name="'.$language.'" id="'.$langid.'" value="'.$lang_active.'"';
if($lang_active=='1'){
echo ' checked="checked"';
}
echo '>
</td>
</tr>';
}
echo '</table>
<input type="submit" name="submit" value="Update" >
</form>
</div>';
mysqli_close($dbc);
