if(is_array($_POST['cbox'])) $violation_save=implode(',',$_POST['cbox']); else $violation_save=$_POST['cbox'];
mysql_query("UPDATE tblcitizen SET license ='$license_save', stickerno ='$stickerno_save', fname ='$fname_save', mname ='$mname_save', lname ='$lname_save', no ='$no_save', street ='$street_save', city ='$city_save', bdate ='$bdate_save', violationplace ='$violationplace_save', dd ='$dd_save', mm ='$mm_save', yy ='$yy_save', hh ='$hh_save', min ='$min_save', ampm ='$ampm_save', violation ='$violation_save', type ='$type_save', officer ='$officer_save', date ='$date_save', ttime ='$ttime_save' WHERE id = '$id'")

我想编辑一些已注册的帐户,如何从数据库中检索1个或多个复选框的值。
为更好的答案而编辑
if(is_array($_POST['cbox'])) $violation_save=implode(',',$_POST['cbox']); else $violation_save=$_POST['cbox'];
您的查询将使用cbox数组,如果它是一个数组(如果选中了多个复选框,则将其转换为带逗号的字符串),否则仅插入一个不带逗号的复选框值。
要获取值,只需读取字符串,然后将其与php strpos()比较即可
<?
// Get the checkboxes that were previously selected
$result = mysql_query("SELECT violation FROM tblcitizen WHERE id = '$id'") or die(mysql_error());
while ($row = mysql_fetch_assoc($result)) {
// put the string into a variable
$mystring = $row['violation'];
}
// use a ternary to determine if this checkbox exists
// if so, make the variable $checked to check the checkbox, otherwise leave it blank
$checked = (strpos($mystring, 'Jaywalking')) ? 'checked' : '';
?>
// write the checkbox to the page. and echo the contents of $checked
// if it was found with strpos() then it will be checked, otherwise it will not be
// <?= ?> is a quick way to echo a variable without the echo command
<input type='checkbox' name='cbox[]' value='Jaywalking' <?=$checked;?> />
