php - 如何在数据库中添加复选框值？

Question

<?php 
 if(isset($_REQUEST['submit']))
 {
        $category = mysql_real_escape_string(implode(',', $_POST['category']));

 }

$ins=mysql_query("insert into fruits (`category`) values ('$category') " ) ;

?>

<form name="form1" method="post" action="">
<input type="checkbox"    name="category[]" value="apple" >Apple
<input type="checkbox"    name="category[]" value="orange" >Orange
<input type="checkbox"    name="category[]" value="mango" >Mango
<input type="submit" name="submit" value="submit"  />
</form>

我需要像 [apple][orange][mango] 这样保存复选框值，但现在它像 apple,orange,mango 这样保存

谁能帮帮我？

使用循环创建你需要的字符串

$category = '';

foreach ( $_POST['category'] as $cat )
{
    $category .= '[' . $cat . ']';
}

$ins=mysql_query("insert into fruits (`category`) values ('$category') " ) ;
